Match the anesthetic listed in the answers below with the most appropriate description of its therapeutic application or pharmacologic effects in the items below. Answers may be used once, more than once or not at all

a) halothane
b) isoflurane
c) nitrous oxide
d) thiopental
e) fentanyl
f) ketamine
g) procaine
h) bupivacaine
i) tubocurarine

1) Short acting nonbarbiturate anesthetic which produces dissociative anesthesia
2) this gaseous general anesthetic is a halogenated ether with little negative effect on cardiovascular function
3) this gaseous general anesthetic must be used with other agents for complete surgical anesthesia
4) A synthetic barbiturate used for induction of anesthesia
5) an opioid analgesic used in balanced anesthesia










You got it right except for choice 2

Correct MAtching as follows
1) F
2) B
3) C
4) D
5) E

Halothane is a halogenated ethane that is an effective general anesthetic when administered as mixtures with air or oxygen. Its effective MAC is low (0.75%). In few pts, halothane is metabolized into hepatotoxic intermediates. Halothane can cause marked CV effects such as sensitization of heart to catecholamines
Isoflurane is a halogenated ethyl methyl ether. Its effective MAC is higher than halothane (1.15% vs 0.75%). Its use has largely supplanted halothane cuz it allows rapid adjustments of depth of anesthesia, potentiates the effects of mucle relaxants, doesnot lead to formation of hepatotoxic intermediatesm and doesnt sensitize the heart to catecholamines
Nitrous oxide is a gaseous anesthetic with extremely low solubility in blood and consequently, it results in rapid induction of and recovery from anesthesia. It is commonly used as 30% mixture with oxygen. By itself, it cnnot produce surgical anesthesia but it can be used as component of balanced anesthesia in combo with thiopental, the muscle relaxant tubocurarune, and the opiod analgesia fentanyl. It is also used in minor dental procedures cuz of its safety
In neuroleptanesthesia, the pt remains conscious. It is technique of choice when voluntary cooperation of pt is required. It involves co-administration of neuroleptic such as droperidol, an opiod analgesic such as fentanyl, and nitrous oxide/oxygen mixtures
Ketamine is short acting anesthetic which produces dissociative anesthesia. Chemically, ketamine hydrochloride is cyclohexanone. In dissociative anesthesia, pt is sedated and immobilized while experiencing analgesia, amnesia, and a peculiar sensation of dissociation from surrounding
Procaine and bupivacaine are local anesthetics. They block nerve transmission by interfering with voltage gated Na+ channels


*nitrous oxide shouldnot be used in pt's with occluded middle ear.
*Halothane is more potent than nitrous oxide.
*fentanly can be used to treat neuropathic pain in metastatic carcinoma's
*inhalation anesthetic of choice for childrens is halothane
* Iv anesthetic of choice for childrens and young adults is ketamine.






thanks to both of you since you post very good Q's and thus is helping all of us smiling face
