Q

Pre-Op care

Preparing for surgery

  • Bowl Prep: depending on the type of surgery (colon/rectal)
  • Skin Prep/ Hair
    • chlorhexidine gluconate antiseptic solution: antimicrobials to clean skin
  • Hospital gown/ Hair cap
  • No dentures/ jewelry
  • No assistive devices
  • Void immediately before
24
Q

What does the nurse complete for Pre-Op record

Study These Flashcards
A
  • Pre-Op assessment
  • plan of care
  • universal protocol / safety checklist
  • document marked surgical site
25
Completed chart to the OR includes
- Pre-op checklist - H & P - anesthetic assessment - surgical consent - Labs
26
Before induction of anesthesia checklist includes
1) confirm identity, procedure and consent 2) site marked 3) anesthesia machine and medication check completed 4) pulse ox on patient and functioning 5) allergies 6) difficult breathing/ aspiration risk 7) risk of > 500 ml blood loss
27
Before skin incision check list * with nurse, anaesthetist and surgeon
1) identify team members by name and role 2) confirm patient name, procedure, and incision location 3) antibiotic prophylaxis given w/in last 60m
28
Pre-Op: Administer any preanesthetic meds
- In bed, side rails up - observe for reactions - keep surrounding quiet - ordered at specific time it “on call to OR”
29
Pre-Op: transport to pre surgical area
- 30 to 60 min before anesthesia | - patient identification
30
Pre-op: family care
- in waiting room | - keep updated
31
Intraoperative surgical team
- surgeon - anesthesiologist - certified registered nurse anesthetist - circulating nurse and scrub nurse - registered nurse first assistant - certified surgical technicians
32
Intraoperative “Time Out”
In OR every team member verified the patient name, procedure and surgical site
33
Surgical environment zones
1) unrestricted zone: street clothes 2) semi-restricted: scrub cloths/ cap 3) restricted: scrubs/ shoe covers/ caps/ mask * no artificial nails * access limited * surgical asepsis * proper attire
34
Surgical environment
- frequent cleaning and sterilizing | - special ventilation
35
OR safety
Exposure to blood and body fluids—- double gloving !
36
Anesthesia
State of narcosis, analgesia, relaxation and reflex loss Not arousable Need assistance with patent airway and ventilators fun’s toon
37
Stages of anesthesia
Stage 1: beginning anesthesia - calm, can talk, R and pain feeling decrease Stage 2: excitement Uncontrolled movement, possible vomit, increase HR Stage 3: surgical anesthesia - eyes stop moving, muscle relax, may stop breathing w/o machine Stage 4: medullary depression
38
General anesthesia
Inhaled or IV
39
Regional anesthesia
Spinal: injected into subarachnoid space at lumbar (L4 and L5) Epidural: injected into epidural space Local blocks: specific area * awake and aware of surroundings
40
Local anesthesia
Injected into the tissue at the planned incision site Often combined with local block
41
Protecting from injury intraoperative
1) Positioning - braces/ padding - safety straps and side rails - safe transfer 2) verify information 3) check chart for completeness 4) obtain the necessary equipment - circulating RN set up suction, monitor, assist w/ vascular access insertion, comfort measures, and “counts”
42
Intraoperative complications nurses should report
- N/V - Anaphylaxis - Resp complications (hypoxia) - hypothermia • due to anesthesia, corse body temp <98 • warming should be gradual - Malignant hyperthermia - Anesthesia awareness
43
Malignant hyperthermia
Acute life threatening emergency Inherited muscle disorder caused by anesthetic agent Usually occur in the first 10-20 mins after induction but can occur 24 hr after surgery
44
Malignant hyperthermia signs and symptoms
- tachycardia ( >150) early sign - ventricular dysrhythmia - hypotension - oliguria (decrease urine) - eventually cardiac arrest - increase CO2 (early sign) - generalized muscle rigidly (early) - rise in temp is late sign • T raise 2-4 degree every 5 min until core exceed 107
45
Malignant hyperthermia treatment
- d/c anesthesia | - stop surgery
46
Post Op
- Go to PACU - may be 4-6 he depending on surgery - recover from effects of anesthesia until return of baseline cognition, stable VS and no evidence of complications
47
Post Op initial assessment
- Airway, RR/ function - HR/ function - VS and LOC - baseline assessment - Meds/ IV fluids as needed
48
Post op assessment AFTER initial
- VS - LOC - General physical status assessed and documented very 15 mins
49
Post op care Respiratory and cardiac
1) maintain patent airway - may have plastic airway in mouth to maintain patent airway - should no be removed until gag reflex is intact 2) maintaining cardiovascular stability - VS, Cardinal rhythm, Skin temp/ color and urine output
50
Post-Op complications
1) Hypotension/ shock - blood loss, hypoventilation, position changes, pooling of blood in extremity, side effect of meds 2) Hemorrhage - early s/s: anxiety/ fear, decreased cardiac output, breathing labored “air hunger” 3) Hypertension/ Arrhythmia - HTN: secondary to pain, hypoxia, bladder distention - Arrhythmia: secondary to electrolyte imbalance, pain, stress, hypothermia, altered R function, anesthetics 4) Hematoma - may need to remove large clot from wound 5) infection - care for dressing and drain - monitor VS, administer antibiotics 6) wound Dehiscence/ evisceration - prevent with abd binder - cover aseptically with moist saline dressing - notify MD immediately 7) paralytic ileus 8) adhesion - scar tissue fused two surfaces together
51
Post-op Pain & N/V management
* pain is 5th vital sign - reposition - relaxing/ diversion techniques - medications • opioids • antiemetic : drug that is effective against vomiting and nausea
52
Post Op elderly considerations
- recover slowly, longer hospital stay, greater risk for complications ``` - treats to recovery include: • pneumonia • decrease functional ability • exacerbation of comorbid conditions • pressure ulcers / Falls • decrease oral intake / GI output • post op delirium ``` - slow medication clearance
53
Post-op respiratory complications
- decrease effects of opioids - FVO: crackles - Use of IS, TCDB “turn cough deep breath” ( can splint while coughing) early ambulation
54
Post op intervention wounds
- wound healing: ongoing assessment of surgical site - drains: assessment of insertion site, proper placement/ drainage - dressing changes: fist change is by member of surgical team, follow orders after that, monitor for drainage and output on Surgical site
55
Post-op complications DVT & PE
- DVT: pain or craning in extremity, edema, red, warm, fever, chills, diaphoresis • compression device or socks • early ambulation or leg exercises - PE: sudden SOB, tachypnea, tachycardia, low grade temp, chest pain, anxiety
56
Wound dehiscence
Wound separates
57
Wound evisceration
Wound and muscle separate and organ protrude
