Q

What is something to be concerned about when using local anesthesia?

A

Many are mixed with epinephrine to decrease blood flow and therefore DELAY absorption of the anesthetic. If absorbed into the tissues or injected IV, can cause tachycardia, HTN, and sense of panic.

Q

What is another term for a regional anesthesia?

A

Block

32
Q
  • Provides loss of sensation to a region of the body without loss of consciousness

A

Regional Anesthetic

*Can be used alone or with MAC

33
Q

What are the two types of Regional Anesthetics?

A
  • Spinal Anesthesia

- Epidural Anesthesia

34
Q

Involves injection of a local anesthetic into the CSF found in the subarachnoid space, usually below the level of L2.

–> Local anesthesia mixes with CSF. Various levels of anesthesia are achieved depending on the extent of spread.

A

Spinal Anesthesia

*Causes autonomic, sensory, and motor blockade

35
Q

What are some side effects of an autonomic blockage?

A

May cause hypotension d/t vasodilation

36
Q

Involves injection of local anesthesia into the epidural space via a thoracic or lumbar approach.

–> Anesthetic does not enter the CSF; works by binding to nerve routes as they enter and exit the spinal cord.

A

Epidural Anesthesia

*sensory pathways are blocked but motor fibers remain intact

(Vasodilation may cause hypertension)

37
Q

What is an important consideration to take when giving an epidural anesthesia?

A

Monitor respiratory rate and depth

38
Q

  • Procedures may be performed outside of the OR environment
A

MAC/ conscious sedation

40
Q

such as fentanyl or meperidine (demerol)

Uses during Anesthesia: Induce & maintain anesth.,↓ stimuli, provide analgesia during surgery & recovery in PACU

A

41
Q

What are some anaphylactic reactions?

A

  • Can cause tachycardia, hypotension, bronchospasm
  • Antibiotics and latex are common causes
42
Q
  • Rare; results from exposure to certain anesthetic agents (Succinylcholine/Anectine especially with volatile inhalation agents)
  • Defect of hypermetabolism of skeletal muscle resulting from altered control of intracellular calcium
