Abstract
Using methoxyflurane and paying critical attention to maintenance of body temperature, tracheal aspiration and fluid replacement, guineapigs were rendered suitable for intraperitoneal operations lasting up to 3 h. Anaesthetic mortality was less than 2%. A technique of small-bowel anastomosis was developed using interrupted soluble sutures meticulously placed 1 mm apart and taking bites 1 mm deep. Survival was 95%.
