Abstract

Deep hypothermia is now employed for open heart surgery in infants. The method of surface cooling infants to 25° C and then by-pass cooling down to 15–20° C prior to exsanguination is described. This provides a still heart and ideal operating conditions. The infants are re-warmed on by-pass. Some of the physiological effects of hypothermia and the methods employed to counteract these are discussed. The aims are to reduce temperature gradients, improve cerebral oxygen supply, avoid arrhythmias and secure haemostasis. The experience in 33 operations is outlined. Seventeen patients were under one year of age.
