The Management of Infants for Cardiac Surgery under Deep Hypothermia

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 haemos… Show more

“…Several palliative operations were developed because corrective surgery in babies under 10 kg only became feasible about 1969 when deep hypothermia (18⁰c) and circulatory arrest became a viable option. [7] Safety was enhanced by the addition of carbon dioxide to the oxygenator gas during cooling so that the corrected CO2 remained normal and the hemoglobin -oxygen dissociation curve moved to the right. This increased oxygen release to the tissues prior to circulatory arrest.…”

“…Following resuscitation, the hypothermic one recovered normally but the other one developed cerebral palsy and died young (3). By the early 1970s, we were familiar with induced hypothermia for infant cardiac surgery (3) and neurosurgery which provided brain protection, and also with induced hypotension with sodium nitroprusside which reduced bleeding. Both these adjuncts provided added safety and were used for many years in conjunction with liver tumor surgery (2).…”
