41. Extremely Profound Hypothermia

Circulation in profound hypothermia.

HIBERNATING MAMMALS MAINTAIN effective cardiac action and circulation at temperatures of 5OC for prolonged periods of time [13, 15, 191. Nonhibernatom, on the other hand, undergo cardiac failure and expire at low body temperatures unless rewarmed and resuscitated within a short time [3, 171. Artificial circulation with a pump oxygenator has improved the tolerance of profound hypothermia and dog...

Accidental profound hypothermia.

A 3-year-old boy who had been exposed for at least 15 hours in an air temperature of approximately 0°C, was found to have a rectal temperature of 17°C about 20 minutes after he arrived at the hospital. He was rewarmed to 34°C in a bath of water at a temperature of 37-38°C during a period of 2 hours 15 minutes. He was also given large amounts of intravenous bicarbonate at the same time. Complica...

Cardiopulmonary resuscitation following profound immersion hypothermia.

A case is presented in which prolonged resuscitation and rewarming was performed following post-rescue cardiopulmonary arrest in severe immersion hypothermia. The rescue and resuscitation techniques necessary to optimise outcome in such cases are described.

Open Cardiac Surgery during Profound Hypothermia

On Tuesday, 31st January 1961, I was privileged to assist at an operation performed y Mr. Ronald Belsey at the Bristol Royal Infirmary, for closure of an atrial septal e?t (A.S.D.) under profound hypothermia. This was the first case to be allotted 0 a student dresser, although the sixth one in the profound hypothermia series in r^stol, and an account of it may be of both topical and historical ...
