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: (A) Minimal change in depth of anaesthesia, (B) Slower emergence from anaesthesia, (C) Faster induction of anaesthesia, (D) There is no difference
Answer is C. 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.
