During maintenance of a general inhaled anaesthetic for urgent non-obstetric surgery, one would expect this difference in the pregnant patient versus a non-pregnant patient
In pregnancy, FRC of lungs is decreased and minute ventilation is increased, which results in increase in rate of change of alveolar concentration of inhaled anaesthetic. This increases speed of induction.
Minimal change in depth of anaesthesia
Slower emergence from anaesthesia
Faster induction of anaesthesia
There is no difference
