Summary

SIMPLE HYPOTHERMIA WITHOUT EXTRACORPOREAL CIRCULATION IS USEFUL IN OPEN CARDIAC SURGERY FOR THE CONGENITAL CARDIAC DISEASE IN INFANTS AND NEONATUS. HYPOTHERMIA WAS INDUCED BY IMMERSION TECHNIQUES UNDER DEEP ETHER ANESTHESIA COMBINED WITH THE USE OF LARGE QUANTITIES OF GANGLION BLOCKING AGENTS. THE METABOLIC RATE DECREASED IN PARALLEL WITH THE DECREASE OF THE BODY TEMPERATURE, AND OXYGEN CONSUMPTION WAS REDUCED TO 70% AT 303 K (30 DEG C), 50% AT 298 K (25 DEG C) AND 20% OF THE NORMAL AT 293 K (20 DEG C). THIS METHOD HAS MADE IT POSSIBLE TO DECREASE THE BODY TEMPERATURE TO 293 K ALLOWING CIRCULATORY OCCLUSION FOR 60 MINUTES. IT IS BELIEVED THAT SURFACE COOLING HYPOTHERMIA IS NOT ONLY SAFER AND SIMPLER BUT ALSO WIDENS THE APPLICATION OF OPEN HEART SURGERY IN SMALL INFANTS.
