The Problem of Obesity in Anaesthesia for Abdominal Surgery

ALAN B. NOBLE M.D.1

1 Department of Anaesthesia, Royal Victoria Hospital, Montreal

The physiological changes responsible for the syndrome of hypoventilation in obesity are discussed. This state may be intensified during anaesthesia for abdominal surgery, and an obese person not suffering from hypoventilation may readily develop this condition when anaesthetized. Further studies are in order to establish more clearly the effects of various types of anaesthesia on the altered lung volumes and mechanics of respiration occurring in fat people. It is proposed that relaxant drugs are hazardous. It is, our unconfirmed opinion that spiiinal and epidural anaesthesia allow establishment of adequate respiratory control, with a decreased hazard of immediate postoperative respiratory insufficiency.
