General Anesthesia Flashcards
1
Q
Desflurane
A
Volatile anesthetic 2nd most potent Insoluble Irritating to airways Minimal myocardial depression Fast on and off
2
Q
Isoflurane
A
Volatile anesthetic Most potent Most soluble in blood Irritating to airways Minimal myocardial depression Toxic to liver
3
Q
Nitrous Oxide
A
Volatile anesthetic Least potent Very Insoluble Adjunct to other volatile anesthetics Reduces MAC requirements Few side effects
4
Q
Sevoflurane
A
Volatile anesthetic 3rd most potent Insoluble Does NOT irritate airways Minimal myocardial depression Metabolized at higher rates Fast on and off
5
Q
Dantrolene
A
Treats malignant hyperthermia that may be caused by volatile anesthetics or succinylcholine
6
Q
Succinylcholine
A
Can cause malignant hyperthermia
7
Q
Etomidate
A
IV induction agent
Respiratory depression but no cardiovascular depression
Can’t be antagonized
8
Q
Ketamine
A
IV induction agent Phencyclidine derivative NMDA receptor antagonist Dissociative anesthetic (produces an unusual EEG) Effects: sedation, amnesia, analgesia No respiratory or cardiovascular depression Can't be antagonized Causes emergence delirium
9
Q
Methohexital
A
Oxybarbiturate
Can be used for induction
10
Q
Propofol
A
Newest anesthetic induction agent Can be used for maintenance and sedation Cardiovascular and respiratory depression Can't be antagonized GABAa beta2 receptor
11
Q
Thiopental
A
Thiobarbiturate
Can be used for induction
12
Q
Alfentanil
A
Opioid
Potent, fast onset, short duration
13
Q
Fentanyl
A
Analgesic-opioid Highly lipid soluble Very potent Fast onset Short duration Antagonized by Naloxone Reduces MAC of volatile anesthetics Respiratory depression
14
Q
Remifentanil
A
Opioid
Metabolized by plasma esterase
15
Q
Sufentanil
A
Opioid
Potent, fast onset, short duration
