Malignant hyperthermia

Autosomal dominant genetic disorder of skeletal muscles in individuals undergoing generalized anesthesia with inhaled agents and muscle relaxants, increase of free calcium produces muscle contraction, fever, tachycardia, hyperkalemia, acidosis

New cards
6

Propofol

Intravenous anesthetic, GABAA channel agonist

New cards
7

Midazolam

Short-acting benzodiazepine, GABAA channel allosteric activator, increases frequency of channel openings, preopertaive drug producing anterograde manesia, anxiolysis and sedation

New cards
8

Opiate antagonist, reversal agent

New cards
11

Etomidate

Intravenous anesthetic, minimal cardiac and respiratory depressant effects

New cards
12

Ketamine

Inhibits NMDA glutamate channels, produces dissociative anesthesia and may produce emergence phenomena

New cards
13

Emergence phenomena

Disorientation, sensory and perceptual illusions, vivid dreams following anesthesia, euphoria

New cards
14

Dissociative anesthesia

Catatonia, amnesia and analgesia without loss of consciousness

New cards
15

New cards
24

Cocaine

Local anesthetic, used topically for ear, nose and throat procedures, vasoconstriction limits bleeding

New cards
