Standard departmental protocol for caesarean delivery
under general anaesthesia was used with metoclopramide
and ranitidine administered orally for aspiration
prevention. After preoxygenation, general anaesthesia
was induced using i.v. thiopentone 5 mg/kg followed by
succinylcholine 1.25 mg/kg, and, until delivery, maintained
with sevoflurane at an expired concentration of
0.5-0.7% in a 50% gas mixture of nitrous oxide/oxygen.
After ligation of the umbilical cord, sufentanil 0.5 μg/kg
and atracurium 0.35 mg/kg were administered for analgesia
and muscle relaxation and sevoflurane was increased
to 1%.
