2. right extremity ("yes" on R leg, "no" on L leg)
3. pause before surgery, call "time out" to go through all checks
- surgical care improvement plan (SCIP)
- surgical safety checklist
- teamSTEPPS + SBAR: communication methods
35
members of the surgical team

- surgical technologist
- speciality nurses
36
robotic assisted surgery

37
benefits of MIS (minimally invasive robotic surgery)

smaller incisions,
reduced blood loss,
faster recovery time,
less pain after surgery
38
athroscopic surgery
- surgery on shoulders, knees, hips
39
anesthesia
induced state of partial or total loss of sensation, occurring with or without loss of consciousness
40
what is anesthesia used for?
- used to block nerve impulse transmission
- suppress reflexes
- promote muscle relaxation
- achieve a controlled level of unconsciousness
41
general anesthesia
- reversible loss of consciousness induced by inhibiting neuronal impulses in several areas of the CNS
- involves a single agent or a combination of agents
- total LOC, no gag reflex, muscles relaxed
*main concern: respiratory issues
42
administration of general anesthesia
- inhalation
- IV injection
- balanced anesthesia
43
what is balanced anesthesia?
- Combination of IV drugs and inhalation agents used to obtain specific effects
- Example: Thiopental for induction, nitrous oxide for amnesia, morphine for analgesia, pancuronium for muscle relaxation
44
adjuvants to general anesthetic agents
- hypnotics
- opioid analgesics
- neuromuscular blocking agents
45
hypnotics and opioid analgesics can be used for:
- sedation before surgery,
- IV moderate sedation for short procedures, and
- as an adjunct to general anesthesia during surgery
46
neuromuscular blocking agents are used for:
- to relax the jaw and vocal cords immediately after so the endotracheal tube can be placed
47
example of local anesthesia
lidocaine, novocaine at the dentist
48
local anesthesia
- Briefly disrupts sensory nerve impulse transmission from a specific body area or region
- provides a reversible regional loss of sensation in a predetermined area of the body to reduce pain and facilitate the surgical procedure
- Delivered topically and by local infiltration
- Patient remains conscious and able to follow instructions, gag reflex is intact
49
regional anesthesia
Type of local anesthesia that blocks multiple peripheral nerves in a specific body region
- Field block
- Nerve block
- Spinal block
- Epidural block
50
what is regional anesthesia often used for?
- when pain management after surgery is desired
ie. TKR
51
regional anesthesia: field block
around operative area – dental surgery, hernia
52
regional anesthesia: nerve block
around one or several nerves for the involved area – joint replacement
sites:
- intercostals (chest and abdomen)
- brachial plexus- C5&C6 (upper arm)
- cervical plexus- C1 (btwn jaw and clavicle)
53
regional anesthesia: spinal
injection of anesthetic agent into the CSF (subarachnoid space above L3) – common for lower abdomen
- numbness from the nipples down
54
regional anesthesia: epidural blocks
injection into the epidural space (subdural space, below L3) – common for LE surgeries, or surgeries in the “saddle area”
- numbness from the hips down
- s/e: hypotension, HA
55
how is anesthesia administered?
Spinal or epidural anesthesia is administered by inserting a spinal needle between the second and third or the third and fourth lumbar vertebrae (L2-3 or L3-4). The patient is placed in the flexed lateral (fetal) position (shown here) or seated on the edge of the operating bed with the back arched and the chin tucked to the chest.
56
spinal anesthesia administration
A large needle is inserted to the surface of the dura mater, and a second, smaller needle is passed through the first to penetrate the dura mater and arachnoid mater. An anesthetic is injected, sometimes through an indwelling catheter, directly into the cerebrospinal fluid in the subarachnoid space.
57
epidural anesthesia administration
Epidural anesthesia (viewed from the side). The needle is inserted to the surface of the dura mater, and the anesthetic is injected, usually through an indwelling catheter, into the epidural space.
58
The nurse's role in providing regional anesthesia includes
- Assisting the anesthesia provider
- Positioning the patient comfortably and safely
- Offering information and reassurance
- Staying with the patient and providing emotional support
- Observing for breaks in sterile technique
- Recognizing and responding to signs and symptoms of possible reactions to the anesthetics
59
conscious sedation
- IV delivery of sedative, hypnotic, and opioid drugs to reduce the level of consciousness.
- Patient maintains a patent airway and can respond to verbal commands.
- Amnesia action is short with rapid return to ADLs.
- CANNOT DRIVE!!
- Etomidate, diazepam, midazolam, meperidine, fentanyl, alfentanil, and morphine sulfate are the most commonly used drugs.
59
preventing injury durying surgery: interventions
- proper body position (for surgery)
- prevent pressure ulcer formation (foam devices)
- prevent obstruction of circulation, respiration, nerve conduction
60
common skin closures
- interrupted sutures
- continuous sutures (interlocking stitch)
- staples
- stay (retention) sutures
- retention bridge
- tapes
61
skin closures are used to
- hold wound edges in place until wound healing is complete
- occlude blood vessels, preventing poor clotting and hemorrhage
- prevent wound contamination and infection
62
absorbable sutures
- dissolve over time by body enzymes
63
nonabsorbable sutures
- become encapsulated in the tissue during the healing process and remain in the tissue unless they are removed
- body enzymes do not affect nonabsorbable sutures
64
wound suturing involves
pulling the edges together under the skin and then closing the layers one at a time
65
postoperative phase begins with
- completion of surgery and transfer to PACU, ambulatory care unit, or ICU
66
phases of posteroperative
- phase I
- phase II
- phase III
67
PACU stands for
postanesthesia care unit
68

- Has ACLS training
- Makes knowledgeable, critical decisions if needed
- Facilitates discharge (if ambulatory care) or hands off to nurse generalist
70
post-op phase: assessment (history)
- review preoperative assessment (did the patient come in A&O, talking and moving all extremities? if patient has expressive aphasia and L sided weakness pre-op, expect it post op.)
- identify potential surgical complications (ie pupil abn size, VS abnormalities- BP, drainage, swelling, bleeding)
71
post-op phase: respiratory system assessment
- Assess for patent airway, adequate gas exchange
- Note artificial airway, if applicable
- Check oxygen delivery device, if applicable
- Check lungs every 4 hours for first 24 hours following surgery (more frequently if needed); then follow agency policy
- RR
- SPO2
- color (pink, warm or cool, cyanotic)
72
post-op: CV assessment
- Assess vitals and compare with baseline
- Report BP changes that at 25% higher or lower than baseline

73
post-op: neuro assessment
- Cerebral function and level of consciousness
- Orientation to person, place, time and situation
- Prevent post op delirium
- Motor and sensory assessment important (after general anesthesia)
- Motor function—simple commands; patient to move extremities
- Return of sympathetic nervous system tone: gradually elevate head and monitor for hypotension
74
post-op: fluid, electrolyte, acid base balance assessment
- Intake and output (I&O)
- Hydration status
- IV fluids
- Acid-base balance
- Nasogastric (NG) tube drainage (metabolic alkalosis/hypokalemia)
75
questions to consider post-op: IV fluids
* Which type of solution is infusing and with which additives?
* How much solution was remaining on arrival?
* How much solution was infused in the transport time from PACU?
* At what rate is the infusion supposed to be set? Is it?
76
questions to consider post-op: tubes/fluid losses
* Is there a nasogastric or intestinal tube?
* What is the color, consistency, and amount of drainage?
* Is suction applied to the tube if ordered? Is the suction setting correct?
* Is there a Foley catheter?
* Is the Foley draining properly?
* What is the color, clarity, and volume of urine output?
Is there wound drainage? – check drains and dressings – needs to be accounted for in I&O
77
acid-base balance is affected by:
- the patient's respiratory status;
- metabolic changes during surgery; and losses of acids or bases in drainage.
For example, NG tube drainage or vomitus causes a loss of hydrochloric acid and leads to metabolic alkalosis
