Infantile pyloric stenosis is the most frequently encountered infant gastrointestinal obstruction in most general hospitals. Although the primary therapy for pyloric stenosis is surgical, it is essential to realize that pyloric stenosis is a medical and not a surgical emergency. Preoperative preparation is the primary factor contributing to the low perioperative complication rates and the necessity to recognize fluid and electrolyte imbalance is the key to successful anaesthetic management. ⋯ Surgical correction was undertaken at an average age of 5.6 wk, and the average weight of the infants at the time of surgery was 4 kg. A clinical diagnosis of pyloric stenosis by history and physical examination alone was made in 73% of the infants presenting to The Hospital for Sick Children. All the infants received general anaesthesia for the surgical procedure and there were no perioperative deaths.

To ascertain the anaesthetic complications requiring post-anaesthetic respiratory support in a large obstetrical hospital, the hospital records of obstetrical patients admitted to an adjacent general intensive care unit (ICU) were studied. Obstetrical patients who required mechanical ventilation following anaesthetic complications were identified and their hospital records reviewed. In a ten-year period there were 61,435 women delivered at the Mater Mothers Hospital (MMH) in Brisbane, Queensland, Australia. ⋯ Complications included anaphylaxis, high block and failure of tracheal intubation. The incidence of a major complication of a GA causing admission to the ICU was 1 in 932 and for RA was 1 in 4177 when these were given for delivery (P less than 0.01). If a complication requiring ICU admission and mechanical ventilation is used as the criterion of safety it appears that RA is safer than a GA for delivery.
