Abstract
Twenty-six patients manifesting severe pregnancy-induced (PIH) or pregnancy-aggravated (PAH) hypertension who presented for emergency Caesarean section under general anaesthesia were studied. All patients came from a previously identified high risk group—namely > 25 yr, multiparous and with diastolic arterial pressures sustained at > 120 mm Hg. Our standard accelerated induction technique for the management of severely hypertensive mothers was modified to include the use of fentanyl and droperidol before induction. This modification of the induction sequence produced a clinically significant amelioration of the reflex sympathetic hypertensive response to laryngoscopy and intubation in most mothers receiving antihypertensive therapy, without apparent deleterious effect in the immediate postoperative period to those neonates unaffected by intrauterine asphyxia.
