Q

What is Surgery?

A

A procedure performed in a variety of settings including hospitals, or clinics, to treat disease, injuries, and deformities by operation and instrumentation.
The procedure relies on an interprofessional team, including the patient, nurses, doctors, and other healthcare providers to ensure continued patient safety throughout the journey. Surgery is performed for a number of reasons including:
* Diagnosis
* Cure
* Palliation
* Prevention
* Cosmetic improvement
* Exploration

Q

PREOPERATIVE PHASE

A

Regardless of where on the body the surgery will be performed, the nurse plays a pivotal role in the preoperative phase of a patient’s surgical journey. The preoperative phase is the time period between the decision to have surgery and the beginning of the surgical procedure.
To perform this role safely and with person-centred considerations, the nurse must understand:
1. The patients’ diagnosis
2. Pathophysiology of the disorder
3. What procedure is planned and what recovery is expected

Q

Patient Interview

A

Completed by the nurse, the preoperative patient interview:
* is to ensure continuity of care
* is completed either in advance or on the day of surgery
* can occur at the hospital’s pre-admissions clinic / wards / surgeon’s clinic or room

Q

Primary Purposes

A

The patient’s health information, procedure details, readiness for surgery, and postoperative support are crucial aspects of the surgical process. Supports include deep breathing exercises, mobility, pain management, fasting requirements, and preparation of the bowel and skin. Consent is obtained, and preoperative diagnostic testing is completed. Risk factors like comorbidities, allergies, smoking, obesity, nutritional status, age, and genetic factors must be considered. Patients may enter the Enhanced Recovery After Surgery (ERAS) pathway to optimize preoperative organ function and reduce complications.

Q

Preoperative Fasting

A

Nil by mouth (NBM) is a method of limiting food and fluid intake to prevent pulmonary aspiration and postoperative nausea/vomiting. Failure to follow NBM instructions can lead to procedure cancellations. Traditional NBM orders include morning and afternoon procedures, while current fasting guidelines allow light breakfast up to 6 hours before surgery and maximum 200mls of unsweetened fluids.

Overall goal
The process involves establishing baseline data, confirming patient identification, assessing psychological readiness for surgery, identifying physiological risk factors, assessing medication use, identifying cultural or religious influences, and ensuring the patient understands the procedure and has received adequate information. This helps in predicting postoperative outcomes.
26
Correct patient identification
* patient (or carer if required) verbally confirms full name, date of birth and address * 3 points of identification match patient name band and all paperwork
27
Past History
* all previous medical diagnoses * current comorbidities * any previous surgeries - including dates, any associated problems, anaesthetic concerns * menstrual history * previous pregnancies - including dates, type of delivery, any associated problems * past hospitalisations * family history * any allergies e.g. seafood, latex, iodine, tapes
28
Social History
* smoker * alcohol intake * illicit drugs * history of falls * current place of employment / role * previous role if currently unemployed * does the patient live with anyone * who is the patient's next of kin in an emergency * who will be collecting the patient from hospital * who will be caring / staying with the patient after discharge
29
Medications
* known drug allergies * known adverse effects * all prescribed medications - including ones not currently being taken * over-the counter medications - including creams * herbal / supplementary / alternative * did the patient bring their medications with them to the hospital? * any medications ceased in the last month * has the patient taken any medications on the day of surgery? * the nurse should be particularly concerned about anticoagulants, immunosuppressants, anticonvusants, narcotics, antihypertensives, sedatives, endocrine replacement medications - missed / taken doses can result in complications such seizures, haemorrhage, withdrawal
30
Physical Assessment / Examination
* baseline vital signs - HR, RR, BP, SpO2, temperature * weight * height * BGL * when assessing systems (if required), target specific questions to determine if the patient has any potential disorders i.e. hypertension, asthma, GORD, history of falls, altered sensation to limbs, incontinence, vision / hearing loss etc.
31
Diagnostics
* during the preoperative interview / assessment, it is the nurse's responsibility to ensure results of all imaging / investigations ordered preoperatively are available either in the patient's chart or online. Any abnormal results should be conveyed to the medical team prior to surgery: ○ urinalysis ○ BGL ○ ECG ○ CXR, USS, MRI ○ bloods - electrolytes, full blood count, coagulation profile, drug levels, blood type and cross match ○ BHCG (pregnancy test) ○ swabs
32
Patient identification- theatre checklist
○ confirm patient identity ○ patient have must have two ID bands on - usually wrist and ankle - white = no allergies - red = allergies
33
Consent- theatre checklist
○ ask the patient if they have signed a consent ○ confirm consent has been signed by visualising the signed document ○ if consent has not been signed then the team performing the procedure need to be informed
34
Allergies- theatre checklist
○ list all known allergies, not just medication allergies - tapes - latex - iodine - medications
35
Patient preparation- theatre checklist
○ the patient must be nil by mouth - when was the last time the patient ate - when was the last time the patient drank ○ did the patient have a pre-medication ○ has the patient taken any regular medication on the day of surgery ○ is the patient pregnant - don't assume if a female patient is of child-bearing years, a pregnancy test must/may need to be completed
36
Patient alerts- theatre checklist
○ is the patient isolating - why? ○ do spinal precautions need to be followed ○ BP restrictions - previous mastectomy - regional lymph node dissection vs lymphadenectomy
37
Prostheses- theatre checklist

41
charts - theatre checklist
○ adequate quantity of patient labels ○ all current documentation and charts ○ past history
42
Diagnostics- theatre checklist
○ results of all investigations
43
Transport to Theatre
The patient's ward nurse is informed about the theatre/operating team's readiness for the procedure. An orderly is contacted for transport, and the registered nurse escorts the patient to the operating rooms. Documentation and XRs are transported, and bed rails are lifted for safety. A blanket is provided, and handover is given to the perioperative nurse.
44
INTRAOPERATIVE PHASE Perioperative Holding Bay
* specialised waiting area adjacent to the operating rooms * often contains multiple bays for numerous patients * minor procedures can occur in this area ○ IVC / ART line insertion, removal of casts, dressings * patient's family / carer can occasionally accompany the patient into the holding bay for support and to reduce anxiety ○ young children / elderly / confused
45
INTRAOPERATIVE PHASE Handover
The perioperative nurse receives handover from the ward nurse and follows a theatre checklist. They confirm patient identification, determine allergies, confirm planned procedure, sign consent, review patient assessment, perform vital signs, determine if pre-medications are administered, and determine the patient's fasting duration. They also verify patient's full name, date of birth, and current address.
46
INTRAOPERATIVE PHASE
The intraoperative phase extends from the time the patient is admitted to the theatre holding bay until the patient is transported to the postanaesthesia care unit (PACU) for recovery.
47
INTRAOPERATIVE PHASE Medical Review
* surgeon ○ consultant or registrar will check in with the patient and provide an update on progress * anaesthetist ○ airway / respiratory assessment performed if not completed on ward / pre-admission clinic - some organisations will transport the patient to an anaesthetic holding bay ○ IVC inserted ○ IV fluids commenced ○ occasionally a sedative will be administered at this time to ensure the patient is relaxed prior to entering the operating room
48
Infection Control
* designed to minimise risk of infection, cross contamination and to ensure patient safety ○ clean equipment / stock is kept separate from dirty equipment / stock * smooth, one-way flow of patients, staff and equipment ○ clean → dirty ○ holding bay → anaesthetic bay → operating room → recovery → ward
49
Operating Room
* environmentally controlled room with restricted access to reduce the risk of infection ○ cold temperature to inhibit pathogen growth and to decrease risk of pathogen transfer ○ high-intensity lighting for precise view ○ may have ultraviolet lighting which also reduces the risk of airborne pathogen transfer ○ 50 - 60% humidity, again, to reduce growth of pathogens and to decrease static ○ dust filters ○ controlled airflow with high ventilation ○ easy to clean surfaces
50
Unrestricted zone
* central point designed for monitoring / control the flow within the theatre ○ entry / exit of staff, patients, equipment, stores / stock * includes holding bay, staff pick-up points, reception area, PACU * staff can enter this area in their everyday clothes / uniform
51
Restricted Zones
* operating / procedural rooms, scrub bays, rooms / areas for preparing sterile stock / equipment, sterile stock store room * can only be accessed through semi-restricted zones * full PPE, theatre scrubs and shoe coverings can only be worn in this area
52
Intraoperative Nursing Roles
A registered nurse plays a crucial role in the operating team, implementing patient care during the perioperative phase. They have advanced patient assessment skills, knowledge of airway management, cardiac monitoring, asepsis, surgical procedures, and anaesthetic methods.
52
Semi-restricted Zones
* support areas and corridors within the perioperative space * includes store rooms, medication room, PACU corridors that lead to restricted areas * staff can enter this area while wearing theatre scrubs or hospital gowns over everyday clothes / uniform and with shoe coverings
52
Scout Nurse
A circulating nurse, also known as a non-sterile member of the operating team, coordinates all activities in the operating room, requires advanced critical thinking skills, adapts to changes, implements nursing plans, prepares the operating room, checks supplies, supports the instrument nurse, prepares skin prep, and serves as a patient advocate, documenting all patient care and procedure count.
52
Instrument Nurse
A scrub nurse is a sterile member of the operating team, wearing surgical scrubs, gowns, gloves, and PPE. They set up and hand sterile supplies to the surgeon, maintain a close working relationship, perform surgical counts post procedure, monitor the intra-operative environment, and advocate for patient safety.
52
Anaesthetic Nurse
The nurse provides anaesthetic and post-anaesthetic nursing care, assists the anesthetist, prepares equipment for airway management, ensures medications are available, and directs patient care throughout anesthesia. They receive patients, check ID and consent, assist with airway management, monitor cardiac and hemodynamics, have advanced life support qualifications, understand surgery and complications, ensure patient comfort, and act as a patient advocate.
53
Type of Anaesthesia
Individually chosen for each patient depending on: * type of surgical procedure * is muscle relaxation required * patient's past medical history and comorbidities * current patient wellness * equipment available at venue * skills of operating team
53
Anaesthesia
A pharmacologically induced lack of sensation. Involves the complex administration of a number of medications.
53
Anaesthesia goal
To manage the biological responses to surgery while minimising patient risks
54
Classification general
* loss of sensation with loss of consciousness * combination of sedation, analgesia and muscle relaxants ○ can be combination of routes including IV, inhalation * with muscles relaxants, patient loses sympathetic nervous system reflexes ○ gag, cough, vomit * required advanced airway management ○ endotracheal intubation (ETT), laryngeal mask ○ please review this table for a review of the advantages and disadvantages of general anaesthetic
55
Classification Regional
Nerve block is a procedure where a local anesthetic is administered into a nerve bundle, resulting in long-lasting loss of movement and sensation. It is used for invasive procedures like amputations and skin grafting, and can cause long-lasting loss of sensation. Examples include spinal, epidural, caudal, and peripheral blockages. Spinal block involves a one-shot injection into the spinal fluid, while epidural block involves continuous infusion and anesthetic for 4-5 days postoperatively.
56
Dermatome levels
must be regularly assessed until full sensation has returned * the area of skin that is supplied by a single spinal nerve is known as a dermatome * our sensory fibres respond to pain, temperature, touch and pressure and are similarly affected by local anaesthetic drugs * nurses need to assess the patient to determine the level of where the patient is ‘blocked’ to * the ice test is used to check for sensation * both left and right sides must be assessed and compared
57
Bromage Score
used to assess movement ability of the lower extremities after regional anaesthesia administered * rates the patient’s ability to move their feet and legs * patient's received a score from 0 (full movement) to 3 (no movement) * motor block assessment should be conducted as per the following and until full sensation / movement has returned: ○ in the recovery room ○ on return to the ward / unit from the operating suite ○ at the start of each shift ○ prior to ambulation
58
Local
* loss of sensation without loss of consciousness * induced subcutaneously via infiltration (needle through the skin) * can be administered topically - nebulised, ointment / cream (EMLA, ANGEL cream), aerosolised * used for minimally invasive procedures e.g., removal of a skin cancer, suturing, removal of a foreign body, insertion of IVC, collection of bloods
59
Procedural Sedation
* similar to general * loss of sensation with loss of consciousness ○ sedative (e.g., propofol), analgesic, and / or anxiolytic (medication to reduce anxiety eg midazolam) * patient can usually maintain their own airway * patients may require airway management if deep sedation required to complete procedure * used for short, minor procedures e.g., joint relocations, paediatric suturing, fracture reductions, eye surgery, colonoscopy
60
Analgesia
* from beginning of induction with propofol to unconsciousness * patient has a decreased awareness of pain, and has amnesia * respirations are regular * ends with loss of consciousness
61
Excitement
* from loss of consciousness to beginning of regular respirations * patient has enhanced reflexes - they may try to talk, move around, may vomit * heart rate and BP may rise
62
Surgical Anaesthesia
four planes of anaesthesia; ○ Plane 1 – light anaesthesia ○ Plane 2 – loss of blink reflex, no longer responsive to non-painful stimuli, reflex-like responses to pain ○ Plane 3 – deep anaesthesia; no movement. Airway and breathing assistance needed ○ Plane 4 – diaphragmatic respiration only, cardiovascular and respiratory support needed
63
Medullary paralysis/overdose
* fixed and dilated pupils * cessation of breathing and circulatory collapse * death
64
Intraoperative Complications
Surgery is not without risk and a critical event can occur at any stage. This is why many safety checks are undertaken at every stage of the perioperative journey. Under anaesthesia and postoperatively, the patient is closely monitored. * cardiac arrhythmias * aspiration of stomach contents * hypoxaemia * hypovolaemia
65
POSTOPERATIVE PHASE
The final phase of the surgical journey - the postoperative period begins immediately following surgery when the patient is transferred to recovery and continues until the patient is discharged from the venue. Depending on the type of surgery that was performed, this phase can be brief, only lasting a few hours, or it can be prolonged and involve many months of rehabilitation.
66
Recovery
Post anaesthetic care unit (PACU) is a critical area providing expert nursing care after surgery. It is located near operating rooms and is designed to help patients recover from anesthesia. Key to preventing adverse events include close observation, frequent vital sign assessments, regular reassessments, early recognition of deterioration, prompt intervention, and medication administration.
67
Handover from Operating Room to PACU
* patient escorted by Anaesthetist and perioperative nurse * usually requires 100% O2 being delivered via Hudson mask * detailed clinical handover provided using ISBAR tool ○ vital sign trends ○ volume loss - blood, urine, fluid ○ temperature throughout ○ wounds / dressings / drains ○ medications administered ○ current infusions ○ any intraoperative event ○ plans
68
Initial Nursing Assessment - Primary Assessment
* DRABCD ○ danger ○ response - conscious state ○ airway - patient may require a jaw thrust to maintain airway patency, does the patient have an airway still in situ? ○ breathing - spontaneous, rate, depth, rhythm, quality, breath sounds, supplemental oxygen ○ circulation - colour and temperature of skin, HR (rhythm / rate), BP, SpO2, pulses, capillary refill, temperature ○ disability - conscious state/sedation score, orientation, BGL
69
Secondary Assessment
* systems or head-to-toe assessment * localised pain, nausea * loss of function? * evidence of blood loss? * checking for any abnormalities, wounds, dressings etc.
70
Focused Assessment
* type of focussed assessment is specific to the surgery that was performed ○ surgical site assessment - dressings, drains, incisions, blood loss ○ neurological / neurovascular assessments
71
Discharge from Recovery
The patient's readiness for discharge from PACU depends on their stability and normal vital signs. The nurse assesses the patient using various scoring tools, performing primary, secondary, and focused assessments. The findings are then transferred to ward documentation for trending assessment purposes.
72
Receiving Patient from Recovery
The receiving nurse receives a handover from the recovery nurse when the patient is 'ward ready'. If the receiving nurse is unsure about the patient's status or potential complications, they must clarify these concerns before taking responsibility for ongoing nursing care. The patient must meet discharge criteria to return to the ward. The receiving nurse must assess vital signs, ensure the patient has a patent airway, normal breathing, and no severe pain, review medication charts, and ensure all documentation is completed and the patient is comfortable.
73
First 4 hours Postop
Upon arrival, record return time and complete a full assessment, including DRABCD, vital signs, neurological, neurovascular, surgical wounds, pain, IV assessments, urine output, nausea/vomiting, and BGL. Compare findings with preoperative baseline values and document all findings. Monitor vital signs, neurological, surgical wounds, pain, IV, and urine output, and ensure emesis bag is within reach.
74
Assessments related to intraoperative anaesthetic / analgesia (additional material - not examinable)
Considerations for nursing assessment following patients who have had intrathecal morphine (ITM) and transversus abdominis plane (TAP) blocks - commonly used with abdominal surgery
75
What is ITM
Intraoperative morphine administration improves pain management in abdominal surgery patients and chronic pain patients. Complications include respiratory depression, pruritus, and nausea. Monitoring post-administration includes sedation score, respiratory rate, and oxygen saturation. Naloxone can be prescribed for respiratory depression and sedation.
76
What are TAP blocks
Transversus abdominis plane blocks are a pain management strategy for abdominal surgery patients, using local anesthetic Ropivacaine or Bupivacaine. However, local anesthetic systemic toxicity (LAST) is a concern, causing changes in the central nervous system and cardiovascular systems, necessitating immediate medical attention.
77
nursing care considerations:
The nurse reviews all documentation, including fluid balance charts, medication charts, and postoperative orders. They ensure patient comfort, including pillows, blankets, bed positions, and a buzzer. They maintain an environment controlled with adequate lighting and minimal visitors. Fluid and food reintroduced as per surgeon's orders, depending on surgery type and postoperative complications. They also assess the patient's emotional state and provide support as needed.
78
Frequency of reassessments in the first 4 hours
Reassessments will need to occur as per organisational guidelines, but is usually: * every 30 minutes until stable * then hourly for the next 4 hours * then every 4 hours for the next 24 hours
79
Immediate Potential Postoperative Complications
Complications can still occur within the first 4 hours. Prompt escalation of concerns / abnormal findings is vital when caring for a patient in the postoperative period. MET call criteria usually includes: * threatened airway * bradypnoea or tachypnoea - respiratory rate <12 or >25 bpm * hypoxaemia - SpO2 <90% * hypotension - systolic BP <90 * bradycardia or tachycardia - heart rate <45 or >100 * sudden fall in conscious state - GCS drop of >2 points * serious concern about uncontrolled pain * haemorrhage - check site of surgery / dressing for bleeding
80
Ongoing Nursing Management
Postoperative nursing care involves regular assessments, postoperative movement, leg exercises, respiratory function promotion, elimination, GIT functioning, wound healing, rest and comfort, and emotional and spiritual support. These measures aim to prevent complications like DVT, pneumonia, and pain, and promote respiratory function, elimination, and wound healing. Regular position changes and early ambulation are encouraged, and leg exercises are recommended. Proper splinting and elimination techniques are also essential. Wound healing is promoted through a healthy diet and wound assessments. Emotional and spiritual support from Pastoral Care workers can also be provided to support the patient.
81
Wound Care
Nursing interventions for surgical wounds focus on preventing complications, performing assessments, adhering to surgeon's orders, using strict aseptic technique, keeping wound dry and dressing intact, and documenting progress.
82
Nursing assessment and management of surgical wounds includes:
Wound assessments should be performed every time vital signs are assessed, including checking for swelling, bruising, and pain. Patients should be educated about the importance of pain in recovery and the potential for complications. Symptoms of infection include fever, tachycardia, increased pain, purulent drainage, and erythematous tissue. Document dressings, drainage, swelling, bruising, and wound pain.
83
Surgical wound dressings can be grouped into two main categories: Primary dressing
○ placed directly over or in the wound ○ a variety of primary dressing materials are available on the market ○ function is to absorb drainage and then wick it away from the wound edge - Cotton gauze or synthetic dressings may be used for this purpose ○ the layer of primary dressing directly contacting the wound should be non-adherent, unless debridement is desired.
84
Surgical wound dressings can be grouped into two main categories: Secondary dressings
○ placed directly over the primary dressing ○ function is to absorb excessive drainage, provide haemostasis by compression, and protect the wound from further trauma - usually accomplished with a bulky dressing, such as a combine (a pad that has a cotton filling and provides extra absorbency)

Surgical dressings may serve one or more of the following purposes:
* cushioning and protection of the wound * protection from contamination * to absorb wound drainage * to provide support to the wound (splinting/immobilization of an area of the body part or incisional area) * physical comfort for the patient * to improve aesthetic appearance * to maintain a moist environment and prevent cell dehydration * application of medications
86
Other wound management interventions
* Patients with infected wounds may require surgical wound debridement and sterile dressing changes performed under anaesthesia. * Patients also may also require wounds to be managed with a combination of surgical interventions and other treatment modalities, such as hyperbaric oxygenation (HBO), negative pressure therapy, hydrotherapy, use of engineered living skin substitutes, and the topical application of growth factors
87
Debridement
- the act of removing dead and devitalized tissue from a wound - debridement of wounds may be necessary because dead tissue in the wound provides a focus for wound infection - patients with chronic, non-healing wounds may require procedures such as grafting, flaps, and other wound coverage
88
Hyperbaric Oxygenation (HBO)
- increases the capacity of blood to carry oxygen to the tissues - the increased oxygenation assists in cellular restoration, and improves leukocyte migration and phagocytosis, as well as fibroblast function - HBO therapy is administered in a pressurized chamber with the patient breathing 100% oxygen at elevated atmospheric pressures. - benefits for chronic wounds may include reduction in inflammation, oedema, and inhibition of infection.
89
Negative-Pressure Wound Therapy (NPWT)
Negative-pressure wound therapy (VAC) is a clinical treatment used for complex wounds that don't respond to traditional methods. It uses a device to apply constant pressure to a wound filled with a drainage sponge and sealed with an occlusive dressing. The VAC system has three mechanisms: mechanical tension, macro-deformation, and micro-deformation. It's suitable for acute and traumatic wounds, pressure ulcers, chronic open wounds, meshed skin grafts, and skin flaps.
90
SURGICAL DRAINS
Surgical drains promote healing, prevent swelling, reduce the risk of infection and skin breakdown and reduce the need for dressing changes. * When surgeons anticipate large amounts of serosanguinous drainage, they insert a surgical drain ○ exit for air & fluids (serum, blood, lymph, intestinal secretions, bile, and pus) ○ inserted at the time of surgery through a separate small stab wound incision ○ drains may or may not be sutured to the skin
91
Common drain tubes include:
Penrose * penrose drains are a soft ribbon like tube that drains onto gauze or into a pouch * an open drainage system and therefore has a higher potential for infection Jackson Pratt (JP) * a closed drainage system where fluid is collected into a small soft bulb * risk of infection is reduced * commonly used for abdominal, breast and thoracic surgery * review the below patient discharge information video Redivac and Hemovac drains * closed drainage systems * a circular device connected to a tube that sits inside the body * removed fluid by creating low pressure suction in the tube - circular device is squeezed flat, as it slowly opens, creates suction * may have sutures holding the drain in place
92
Nursing Management of Surgical Drains
The postoperative instructions for drain tube requirements should be checked, and drainage should change from sanguineous to serosanguineous to serous. Accurate documentation is required, and PPE must be used for removal. Assessments should include dressing condition, suction requirements, drain clamps, suture presence, potential infection signs, and drainage fluid type. Drainage should be documented on the fluid balance chart and emptied to maintain suction.
93
Removal of Sutures / Staples
The process involves removing sutures or staples as per the surgeon's order, including education, pain explanation, wound care, and infection detection. The equipment needed includes a dressing trolley, dressing pack, saline/chlorhexidine, stitch cutter, staple remover, and steri strips. After removal, the suture line is cleaned, dried, and steri strips applied for new skin formation.
93
Removal of drain tubes
The patient's doctor records the drain tube's readiness for removal in their notes. Before the procedure, check the organization's policy on surgical drain tube removal. The necessary equipment includes dressing, gloves, and PPE. After removal, inspect the tubing for damage, notify the surgeon, and record the date and time. Record drainage on a fluid balance chart and reassess the dressing for excessive drainage.
94
Pain
* pain is whatever the person experiencing it says it is * adequate pain management is an ongoing challenge for nurses and remains a fundamental aspect of high-quality patient care. * failure to adequately manage a patient's postoperative pain can result in adverse psychological and physiological effects, both short and long term.
95

98
Pain Management
A nurse assesses pain and initiates nursing interventions to manage it. They determine the source of pain, manage pharmacological management, check medication charts, escalate to a doctor if analgesics aren't adequate, and consider a multimodal approach. They must be aware of adverse effects of medications, and consider non-pharmacological management such as position changes, support, reassurance, and patient education.
99
Nausea / Vomiting
Postoperative nausea and vomiting (PONV) is a distressing complication of surgery, affecting up to 30% of patients. It can lead to serious consequences like aspiration, fluid volume deficit, and electrolyte imbalance. Pharmacological management includes medication, while nonpharmacological management includes cool face flannel, reassurance, ice chips, and a vomit bag.
100
Nursing Management Post Vomiting
To ensure patient hygiene, wash face and hands, allow mouth rinse or brushing, offer water, monitor fluid intake, perform abdominal assessment, listen for bowel sounds, document volume on fluid balance chart, and document progress notes.
101
Paralytic Ileus
Post-surgery, temporary impairment of gastric and bowel motility can occur due to limited dietary intake, intestine handling, hypokalemia, and prolonged opioid analgesic administration. Small bowel motility usually resumes within 24 hours, while large bowel motility may be limited for 3-5 days.
102
Paralytic Ileus Nursing Management
The patient should remain NBM until peristalsis returns, perform abdominal assessment, monitor bowel sounds, encourage early ambulation, position patient on right side, pass flatus, check medication chart, and provide mouth care. Gradual reintroduction requires clear fluids, light diet, and full diet.
103
Spinal, Epidural & Caudal Anaesthetic
* assess patient for ○ severe headache ○ respiratory depression ○ hypotension ○ sensory response - dermatomes ○ motor response - bromage score * check infusion pump settings * check insertion site for ○ infection ○ swelling ○ catheter movement ○ leaking fluid
104
Other potential postoperative complications
* respiratory complications ○ hypoxaemia ○ pneumonia - secondary to aspiration during surgery ○ atelectasis * cardiovascular complications ○ hypovolaemic shock * GIT complications ○ constipation ○ abdominal distention ○ intestinal obstruction * haematology / vascular complications ○ DVT / PE ○ haemorrhage * surgical site complications ○ wound infection - not evident in the first 48 hours postoperatively ○ wound dehiscence ○ compartments syndrome * neurological complications ○ postoperative delirium ○ headache * urinary complications ○ retention ○ oliguria - urine output < 0.5ml/kg/ hr
105
Planning for Discharge from the Ward
Discharge planning is an ongoing process that begins during the preoperative phase * an informed patient will be prepared for events * the patient will gradually assume more responsibility for self-care
106
Patient / carer must have the following information:
Postoperative care involves following up with patients for symptoms such as fever, tachycardia, increased pain, and respiratory changes. It includes understanding medications, wound care, dressings, bathing requirements, and activities to avoid. Postoperative follow-up includes GP, specialist, and outpatient department. Dietary requirements, nursing support, and interprofessional team referrals are also essential. Patients seek help postoperatively for ongoing pain, wound infection, and medication advice. Written postoperative instructions and support details are provided.
107
Discharge from Day Surgery
Day surgery may include: * outpatients * same-day surgery * short-stay surgery Patients can be discharged when: * alert * mobile * vital signs must be within 20% of preoperative baseline values and stable for > 1hour * have voided * tolerating oral intake - food and fluids * minimal pain, nausea and vomiting - can be pharmacologically controlled * absent / minimal surgical site bleeding - no dressing changes required * can self-care once at home
108
Pharmacology
There are many medications used during the surgical journey. Over the coming chapters, we will take a look at the medications used during the different phases of the peri-operative journey including: 1. H2-receptor antagonists 2. Benzodiazepines 3. Anaesthetic agents 4. Opioids including patient controlled analgesia (PCAs) 5. Antiemetics 6. Anticholinergics
109
Pre-operative medications
Whilst not all patients require pre-operative medications (pre-meds), there are a number of reasons that these are given, including: * Provision of analgesia * Prevention of nausea and vomiting * Promote sedation and amnesia * Decrease anaesthetic requirements * Facilitate induction of anaesthesia * Relieve apprehension and anxiety * Prevent autonomic reflex response * Decrease respiratory and gastrointestinal secretions
110
Benzodiazepines
Diazepam is a short-term medication used to manage anxiety, agitation, alcohol withdrawal, muscle spasm, and sedation. C- It can cause respiratory depression and myasthenia gravis. P-It should be reduced in people with renal or hepatic impairment, elderly, and children. Side effects include drowsiness, oversedation, and hypersalivation. Patients should have completed surgery consent before administering this medication.
111
Midazolam
Procedural sedation, induction of anaesthesia, sedation during ventilation, premedication This medication potentiates GABA inhibitory effects in the CNS, causing various effects like anxiolytic, sedative, hypnotic, muscle relaxant, and antiepileptic effects. C- It can cause respiratory depression and myasthenia gravis. P-It should be reduced in people with renal or hepatic impairment, elderly, and children. Common side effects include hypotension, hiccups, cough, pain, erythema, and arrhythmias. Monitor closely for respiratory depression risks.
112
Ondansetron
N&V associated with cancer chemotherapy, postoperative and radiotherapy induced 5HT3 (serotonin) antagonist Blocks the transmission of 5HT3 in the GI tract thus reducing N&V. C-concomitant use with apomorphine. P-avoid use in patients with prolonged QT interval or ensure K+ and Mg2+ are corrected prior to administration Safe to use in pregnancy and breastfeeding Common – constipation, headache, dizziness Rare – hypersensitivity reactions, ECG changes Educate patients that wafers and dispersible tablets should be placed on top of the tongue to dissolve then swallowed.
113
Droperidol
Used for induction of anaesthesia and prevention of PONV OTHER: Short-term management of severe acute anxiety, agitation or disturbed behaviour, Bi-polar disorder NOTE: doses used for N&V are considerably lower (2.5-10mg) than those used for anti-psychosis (10-25mg). Dopamine antagonist – blocks dopamine receptors C-severe CNS depression, Parkinson’s disease, breast feeding, patients with prolonged QT interval. P-seek specialist advice during pregnancy Common – sedation Rare – prolonged QT interval At higher doses: Respiratory failure, hyperthyroidism, GI obstruction, extra-pyramidal side effects (EPSE) Medication generally only administered in the peri-operative period where patient can be closely monitored.
114

Educate patients regarding side effects and importance of seeking medical support if identified. Warn patient that risks of EPSE increase with prolonged use.
115
Dexamethasone
A synthetic glucocorticoid that has anti-inflammatory and immunosuppressant actions that is used for patients that are at high risk of PONV. Corticosteroid that is 25-30 times more potent than hydrocortisone.
116
Atropine
Premedication to inhibit excessive salivary and bronchial secretions and diminish risk of vagal inhibition of the heart. Bradycardia with haemodynamic compromise Block the action of acetylcholine at the muscarinic receptors of the parasympathetic nervous system (PNS). C-known hypersensitivity to anticholinergic agents, obstructive diseases of the GI tract, reflux oesophagitis, prostatic enlargement, acute angle-closure glaucoma, unstable CVS status, tachycardia P-use with extreme caution in patients with heart disease, HTN, ulcerative colitis, ileus, hepatic and renal insufficiency. Considered to be safe to use in pregnancy and breastfeeding. Tachycardia, palpitations, dry mouth, tremor, fatigue, drowsiness, ataxia, mental confusion As atropine has a short half-life patients should have no ongoing issues related to its administration. Ensure patient has provided a complete medical history prior to surgery to ensure no contraindications are present.
117
Ranitidine
Reduction of gastric pH prior to surgery Competitively blocks H2 receptors on parietal cells, reducing gastric acid secretion. C-known hypersensitivity These medications are generally well tolerated. Rare – confusion, rash, thrombocytopenia, agranulocytosis, leukopenia, hepatitis, hypersensitivity reactions. In the preoperative context, ensure patient swallows all of liquid – generally use effervescent formulation.
118

Infrequent - rash, itch, fatigue, drowsiness, insomnia, dry mouth Rare - gynaecomastia, myalgia/arthralgia, acute interstitial nephritis, peripheral oedema. Educate patient regarding need to swallow tablet whole, and potential side effects.
119
Intra-operative medications
Whilst most of you will not be involved in administering intra-operative medications, you need to be aware of the different types of medications used and their side-effects. These guide many of the assessment requirements that we undertake post-operatively. Medications used during the continuum of general anaesthesia are broken down into the following: * Pre-induction - premedication which was covered in the previous chapter * Induction * Maintenance * Emergence
120
121
Barbiturates
Ultra short-acting CNS depressant inducing hypnosis and anaesthesia. Works within 30-40 seconds Duration of action < 5 minutes Adverse cardiac effects (myocardial depression), hypotension, respiratory depression Usually have minimal postoperative effects because of short duration of action. ^incidence of nausea in patients with barbiturate sensitivity, histamine-triggered nausea and vomiting.
122
Inhalation agents
Induces hypnosis, amnesia and skeletal muscle relaxation Abolition of skeletal muscle reflexes Respiratory depression, hypotension, myocardial depression. Increase risks of PONV Limited analgesia Assess and treat pain during early anaesthesia and recovery Assess for adverse reactions – cardiopulmonary depression with hypotension and prolonged respiratory depression. Monitor for nausea and vomiting
123
Dissociative anaesthetic
General anaesthetic producing profound analgesia. Potent analgesic and amnesic Useful for brief procedures May cause hallucinations and nightmares, increased intracranial and intraocular pressure, increased HR and BP Some patients have ketamine infusions post operatively. Anticipate administration of a benzodiazepine if hallucinations and agitation occur.
124
Neuromuscular blocking agents Depolarizing agent
Mimics acetylcholine depolarising the motor end plate resulting in skeletal muscle relaxation (paralysation) Facilitates endotracheal intubation and promotes skeletal muscle relaxation to enhance access to surgical sites Apnoea related to paralysis of respiratory muscles. Hyperkalaemia occurs with the action of sux., so must not be used in patients with burn or crush injuries due to risk of cardiac arrhythmias and death. Patients with myasthenia gravis should not be given sux., as they may have an ongoing block. As these patients are unable to breathe whilst these medications are in use, full respiratory support and monitoring of haemodynamic status must be in place. Post operatively, monitoring of temperature and levels of muscle strength with temperature changes must occur. Patients may suffer from muscle pains for 24 hours post op so inform patient of this.
125
Analgesia PRINCIPLES OF PAIN MANAGEMENT
Analgesia means loss of sensation of pain (Brown et. al., 2023). Whilst this is not always completely possible, it should be our aim to provide effective pain management for individuals. In the postoperative phase, pain may be directly related to the surgical manipulation of tissue, reflex muscle spasm, positioning during the surgical procedure or the presence of catheters and tubes. Some patients may also have persistent pain from other comorbidities that needs to be considered.
126
OPIOIDS
Opioid analgesics are used for both acute and persistent pain with nociceptive (pain originating in the tissues), acute pain being more responsive to them than persistent or neuropathic (pain originating from nerve damage) pain. Each person is individual in their pain experience and this also holds true to their response to opioid analgesics. What works for one person may not work as well, or at all, for another. This individuality requires us to use different forms of opioid medications in combination with other forms of pain control, including both pharmacological and non-pharmacological until something that works is identified.
127
Morphine
Tablets – 10mg, 20mg, 30mg Oral liquid – 1- 10mg/ml Injection – 5-30mg/ml Injection intrathecal – 200-500microgs/ml Controlled release – 5-200mg tablets, 10-120mg capsules P-adjust dose in patients with renal impairment as risks of respiratory depression and delirium increase. Dose adjustment also required for elderly population and those with hepatic impairment. Monitor for side effects. Ensure controlled release medications are swallowed whole and not chewed, dissolved or crushed. Ensure that patient has antiemetic and stool softeners orders to counteract side effects.
128
Fentanyl

133
ANTIEMETICS - MEDICATIONS FOR NAUSEA AND VOMITING
Nausea is an uneasy stomach sensation often resulting in vomiting. It is a complex process involving multiple nerve pathways and neurotransmitters. It is a protective mechanism to rid the body of toxic substances. In severe cases, it can cause fluid and electrolyte disturbances. Nausea and vomiting can be distressing for patients, especially during the postoperative phase. Various causes and medications are available to manage these symptoms.
134
PATIENT CONTROLLED ANALGESIA (PCAs)
PCA is commonly used in the postoperative period to provide immediate analgesia * an effective method of pain management because it delivers a constant level of an analgesic agent * will contain schedule 8 analgesic medications (opioids) → morphine, fentanyl, tramadol are common examples
135
PATIENT CONTROLLED ANALGESIA (PCAs) Advantages
* enables the patient to receive pain relief without delay ○ increases the patient's sense of control → empowerment * opioid blood concentrations are maintained within therapeutic ranges * prompt management of pain caused by activity ○ patients are able to anticipate activities such as coughing or movement associated with increased pain and provide themselves with an opioid bolus in advance ○ enables increased patient mobility
136
PCA pump modes
1. PCA mode only → demand dose, the patient will only receive a dose of analgesia when they press the PCA button, there is a lock-out period after each bolus dose self-administered by the patient as a safety measure 2. Continuous infusion → a background infusion where the patient will receive a continuous dose of analgesia, cannot be altered by the patient 3. Continuous infusion with additional demand analgesia → the PCA is set for a continuous background infusion as per orders but the patient can self-administer an additional bolus of analgesia as required
137
Nursing Management
1. Always review the medical order, including the section on reportable observations 2. RN must have a thorough understanding of the medication being administered, including common adverse effects 3. When caring for a patient on a PCA, the following reviews / assessments should be performed hourly, unless indicated by the medical orders or organisational clinical practice guidelines: ○ vital signs ○ assess your patient for CNS effects of opioid overdose → respiratory depression, drowsiness, confusion ○ pain assessment ○ device review to ensure there are no problems such as leaking around connections / kinked tubing ○ IVC assessment ○ documentation 4. Good patient education is essential for effective management. Patient must be educated in: ○ Use of the PCA ○ When to use. Patient should not wait for severe pain ○ Explain lockout process ○ Patient must inform nurse if pain not relieved or multiple doses needed
138
Loading Dose:
Some patients will be prescribed a loading dose after the set-up of the PCA. This ensures therapeutic action of the medication is reached immediately after set-up. This is not always ordered so it is essential you check the order carefully for a loading dose.
139
Bolus Dose:
This is the amount of opioid (or other medication) that the PCA pump will deliver when the demand button is pressed.
140
Lockout Interval:
The time from the end of the delivery of one dose until the PCA pump will respond to another demand is called the “lockout” interval. This is to allow the effect of one dose to be felt before another can be given and is one of the safety features of the PCA pump.
141
Continuous Infusion Rate:
Some PCA's will have a background continuous infusion rate ordered along-side the bolus dose. The purpose of a continuous infusion is to help maintain a stable analgesic level. This may enable the patient to make less demands on the PCA. This is not always ordered so it is essential you check the order carefully to determine if a continuous infusion is also required.
142
Lockout:
This is the period of time between demands that a patient cannot exceed and is documented on the PCA order in minute increments (i.e. 5 minutes). For example, if your patient has a successful PCA demand at 1025hrs, if their lock out is 5 minutes, they will be unable to have another dose delivered until 1030hrs regardless of how many times they press the button.
143
Hourly Limit:
In addition to the lock out another safety feature of the PCA is the hourly limit. This is the maximum does that the PCA will deliver in any one hour.
144
Attempts/Demands/Bolus Dose:
This the number of times the patient has pressed the button. It is not the same as the amount/dose that has been delivered to the patient. When reading the PCA on the hour, a patient may have had 12 attempts but only 4 doses delivered in this time. This can indicate if education and/or dose increases/ other forms of analgesia are required.
145
Nursing tip
* the number of PCA demands versus dose deliveries are documented to evaluate its effectiveness ○ if the demands are high compared to the doses delivered, the patient needs reassessment → notify your buddy nurse * PCAs are only suitable for patients that have a clear understanding of the use → patient's with a cognitive impairment or are under the age of 5 will not understand the concepts of self-administering analgesia and they will not be able to comply with the instructions on how to use the device * If a patient normally uses a CPAP machine, this MUST be in place during sleep periods.
