The electrocardiogram of dogs surviving 1.5° centigrade

Abstract The hearts of eight dogs were cooled to asystole for as long as 35 minutes by refrigeration of blood circulated by a pump-oxygenator. The hearts started to beat again upon rewarming of the blood in the extracorporeal circulation and the animals survived the experiment without any clinically detectable sequelae during a one-month observation period. Electrocardiographic recordings throughout the entire procedure and in the postoperative period showed a remarkable absence of serious arrhythmias.

Hemipelvectomy for the management of soft tissue tumors of the lower extremity

Abstract 1. 1. A clinicostudy of twelve cases of malignant soft tissue tumors of the lower extremity and pelvis treated by hemipelvectomy has been presented. 2. 2. It is concluded that hemipelvectomy is an effective and safe operation for the surgical management of soft tissue malignant tumors of the thigh and pelvis. Other than tumor size and position, emphasis is directed to the utilization of the tumors histologic and biologic behavior as a criterion for selecting patients for hemipelvectomy.
