20
Q

What is anesthesia? What is it used for?

A

– anesthesia: induced state of partial or total loss of sensation, with or without loss of consciousness

– used to block nerve impulses, suppress reflexes, relax muscles, and control level of unconsciousness

21
Q

What regions of the body does general anesthesia affect? What is the effect of general anesthesia?

A

– regions:

  • head
  • neck
  • upper torso
  • abdominal procedures

– effect – reversible loss of consciousness by use of a single agent or a combination of agents

22
Q

What are the 5 stages of general anesthesia?

A
  1. stage 1 – analgesia, sedation, relaxation
    • pt can hear everything
  2. stage 2 – excitement, delirium
    • involuntary movement of extremities
  3. stage 3 – operative anesthesia, surgical anesthesia
    • loss of reflexes, depression of vital functions, surgery is ready to move forward
  4. stage 4 – danger
    • more pronounced depression of vital functions
    • if not addressed, can result in respiratory failure or cardiac arrest
  5. emergence – recovery from anesthesia
    • pts will sometimes get sick as they come back – N/V, restlessness, shivering, rigidity, cyanotic
23
Q

What is balanced anesthesia?

A

combination of IV drugs and inhalation agents used to obtain specific effects

24
Q

What are 5 possible complications of general anesthesia?

A
  1. malignant hyperthermia
    • could result as a complication from certain agents
    • causes electrolyte disturbance
      • high calcium
      • increased muscle metabolism
      • acidosis
      • high potassium
    • can treat with dantrolene
  2. overdose
    • especially of concern in the elderly and pts with comorbidities
  3. unrecognized hypoventilation
    • hypoxia – need to check perfusion before and after procedure
  4. complications of specific anesthetic agents
  5. complications of intubation
25
Q

What is local anesthesia? How is it delivered?

A

– local anesthesia: briefly disrupts sensory nerve impulse transmission from a specific area or region; pt remains conscious

– delivered topically and by local infiltration

26
Q

What is regional anesthesia? What are the 4 types of blocks?

A

– regional anesthesia: local anesthesia that blocks multiple nerves in a specific body region

– 4 blocks:

  1. field block: blocks nerves around operative field
  2. nerve block: blocks nerves in or around one nerve or a group of nerves
  3. spinal block: blocks nerves in the CSF and subarachnoid space
  4. epidural block: blocks nerves in the epidural space
27
Q

What are the 5 possible complications of local/regional anesthesia?

A
  1. anaphylaxis
  2. incorrect delivery technique
  3. systemic absorption – can be lethal
  4. overdose – important to obtain proper H & W
  5. local complications
28
Q

What are the 5 ways to treat complications of anesthesia?

A
  1. establish an open airway
  2. give oxygen
  3. notify surgeon
  4. fast-acting barbiturate – usual treatment
  5. epinephrine – for unexplained bradycardia
29
Q

What is moderate sedation? Name some common examples of moderate sedation drugs.

A

– moderate sedation (conscious sedation): IV delivery of sedative, hypnotic, and opioid drugs to reduce LOC

  • pt maintains a patent airway
  • pt can respond to verbal commands
  • amnesia action is short
  • rapid return to ADLs

– common examples:

  • etomidate
  • diazepam
  • midazolam
  • meperidine
  • fentanyl
  • alfentanil
  • morphine sulfate
30
Q

A
  1. breathing
  2. circulation
  3. cardiac rhythms
  4. BP and HR
31
Q

What is the PACU?

A

– postanesthesia care unit

– allows for ongoing evaluation and stabilization of pts after surgery

32
Q

What are the 4 priorities of PACU nurses when caring for pts post-operatively?

A
  1. respiratory status
  2. vitals Q15 minutes– LOC, temp, SpO2, BP
  3. examination of surgical area
  4. discharge from PACU
33
Q

What is an important neurological assessment to make for pts post-operatively?

A

motor and sensory – movement of extremities and return of SNS (gradual elevation of head and monitoring for hypotension)

34
Q

How long after surgery could peristalsis be delayed?

A

24 hours

35
Q

What are the 6 reasons for NG tube insertion during surgery?

A
  1. decompress and drain stomach
  2. rest GI system
  3. heal lower GI tract
  4. enteral feeding route

36
Q

Differentiate between dehiscence and evisceration.

A

– dehiscence: partial or complete separation of outer wound layers

– evisceration: total separation of all wound layers and protrusion of internal organs through wound

37
Q

How long after surgery yields the highest incidence of hypoxia?

A

2nd day after surgery

38
Q

What is pneumonia, and how does it occur? What are 3 preventions for pneumonia?

A

– pneumonia: inflammation of alveoli

– results from accumulation of fluid, aspiration, infection, decreased cough reflex, and immobility

– 3 preventions:

  1. CDB
  2. incentive spirometry
  3. splinting of incision
39
Q

What is atelectasis? Why is it dangerous? What are some signs and symptoms?

A

– atelectasis: incomplete expansion or collapse of alveoli

– impairs gas exchange

– s/s:

  • diminished lung sounds
  • crackles
  • dyspnea
  • cyanosis
  • restlessness
  • apprehension
40
Q

What are 5 treatments for atelectasis?

A
  1. position in semi-Fowler’s

  3. CDB
  4. ambulation
  5. hydration
41
Q

What is hypovolemic shock, and what are the 2 ways it can result?

A

– hypovolemic shock: decreased circulatory blood volume

– 2 ways it can result:

  1. dehydration
  2. blood loss
    • trauma – blunt or penetrating
    • bleeding
42
Q

What is thrombophlebitis?

A

inflammation of vein associated with thrombus formation; AKA DVT

43
Q

What are treatments for thrombophlebitis?

A
  • anticoagulants
