Profound hypothermia with body-surface cooling for use in open-heart
surgery is considered a difficult anesthetic technique because of the
problems of controlling ether anesthesia. This paper describes our
hypothermia technique in detail, with emphasis on its particular usefulness
in open-heart procedures in neonates and infants. The results are based on
our experience with 281 consecutive patients. Guidelines for safe and
effective performance of this technique were established on the basis of
continuous monitoring of the electrocardiogram, electroencephalogram, and
arterial blood pressure. We conclude from our experience that open-heart
operation under profound hypothermia is a safe, effective, and extremely
promising method.
