Anaesthesia · Obstetric anaesthesia: pre-eclampsia and laryngoscopy
Sample itemA woman with severe pre-eclampsia requires general anaesthesia for an emergency caesarean section. Which drug attenuates the pressor response to laryngoscopy?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
D. Remifentanil or alfentanil given with induction
Laryngoscopy and intubation cause severe hypertension that can precipitate intracerebral haemorrhage in severe pre-eclampsia. A short-acting opioid such as remifentanil or alfentanil, or lignocaine or magnesium, blunts this response. Neonatal respiratory depression is anticipated and managed by the paediatric team.
Option by option
A. Ephedrine
Ephedrine is a vasopressor and would worsen hypertension.
B. Ergometrine
Ergometrine causes vasoconstriction and is contraindicated in hypertension.
C. Ketamine as the sole induction agent
Ketamine causes hypertension and tachycardia and is undesirable here.
D. Remifentanil or alfentanil given with induction (correct)
Correct. A potent short-acting opioid blunts the pressor response.
