AWABS - Day 1 SBA questions Flashcards
Anaesthetic gas with excellent anaesthetic properties
Xenon
Why is xenon not used in anaesthesia
Extremely difficult to produce and therefore extremely expensive
Oil : gas partition coefficient
The higher the oil : gas partition coefficient, the more will cross the blood brain barrier
Therefore more potent
Volatility definition
Tendency of a liquid to evaporate into a gas
Inhalation anaesthetic agents important figures
Meyer-Overton hypothesis
Potency of an anaesthetic agent is related to its lipid solubility
Lipid solubility is described in oil : gas coefficient
Blood : gas partition coefficient
Relates to solubility
Lower the blood : gas partition coefficient the faster the speed of onset
Dose of Vecuronium
0.1 mg/kg
Why does rocuronium have more rapid onset than vecuronium
Rocuronium has lower potency so higher doses increase gradients quicker and therefore faster onset time

Approach to statistical questions - cheat system
Parametric refers to normally distributed data
NB. Data is not parametric or non-parametric but rather the tests are. However helps with this cheat to think of it as such
Parametric data
Normal distribution of data
Non parametric data
All data which is not a normal distribution
