Anaesthesia
Question.1
Anaesthetic gas with maximum respiratory irritation
NEET PG Jan-2019
A. Halothane
B. Enflurane
C. Desflurane
D. Sevoflurane
Correct Ans: C
Explanation
Ans:C. Desflurane
◦ Desflurane and isofurane when used for induction cause respiratory irrita-
tion due to their pungent smell leading to breath holding and coughing.
◦ Halothane and sevoflurane do not cause such effects.
Question.2

lowing?

Question.3
Which of the following is not cardiodepressive?
NEET PG Jan-2019
A. Propofol
B. Thiopentone
C. Ketamine
D. Etomidate
Correct Ans: D
Explanation
Ans:D. Etomidate
Major advantage of etomidate:
◦ Cardiovascular stability after induction.
Effects of etomidate induction dose:
◦ Negligible increase in heart rate.
◦ Little decrease in blood pressure/cardiac output.
◦ Little effect on coronary perfusion pressure, while reducing myocardial O2
consumption.

of anaesthesia?
NEET PG Jan-2019
A. BIS
B. Oesophageal contractility
C. Depressed responses
D. Hypotension

Correct Ans: AAnaesthesia NEET PG Jan-2019
Explanation
Ans:A. BIS
Bispectral index:
◦ 1st scientifically validated & commercially available monitor to check depth
of anaesthesia.
◦ Utilizes many parameters (EEG signals, eye blinks) to calculate depth score.
Adequate depth:
◦ Score of 45-60.
Fully awake state:
◦ Score of 100
Completely silent brain: 0.
