Chapter 11 Flashcards
anesthesia
-a state of reduced neurologic function
What are the 3 types of anesthesia?
- general
- local anesthesia
- balanced anesthesia
General anesthesia
drugs that induce a state in which the CNS is altered to produce varying degrees of: pain relief depression of consciousness skeletal muscle relaxation reflex reduction
Types of general anesthesia
- Inhalational anesthetics
- volatile liquids or gases that are vaporized in oxygen and inhaled - parental anesthetics
- administered - adjunct anesthetics
Indications for general anesthesia
used during surgical procedures
adverse effects
-malignant hypothermia
What is malignany hypothermia?
- occurs during or after volatile inhaled general anesthesia or use of the neuromuscular blocking drug (NMBD) succinylcholine
- sudden elevation in body temp (greater than 104 degrees F)
- tachypnea, tachycardia, muscle rigidity
- life thretening emergency
- treated with cardiorespiratory supportive care and dantrolene (skeletal muscle relaxant)

moderate sedation
-can still breath on their own and follow basic commands, but not aware of what is happening
topical anesthesia
- applied directly to skin or mucous membranes
- creams, soulutions, ointments
parenteral anesthetics
lidocaine (xylocaine) mepicacaine procaine tetracaine others local anesthetics
Local anesthetics are used for:
-surgical, dental
local anesthetics are sometimes paired with
ephinephrine (vasoconstrictor) so that to limit bleeding and keep the local anesthetic where it should be
adverse effects
-spinal headache
neuromuscular blocking drugs
also known as NMBDs
- prevent nerve transmission in skeletal and smooth muscle, resulting in muscle paralysis
- also paralyze the skeletal muscle required for breathing
- when used, artificial mechanical ventilation is required
- do not cause sedation or pain relief
