Body hypothermia produced by surface cooling methods is being employed most frequently in neurosurgery to achieve the best results. Surface cooling methods in maneuvering the entire operative process have, however, disadvantages which include ; lack of precise control of the degree of temperature decline, and inability of starting the operation unless optimal body temperature is obtained. In essence too much time is required for an adequate level of hypothermia, thus, hampering the entire procedure. We recently devised a simplified method of not only obtaining optimal body temperature of 27℃ under a considerably shortened period, but also eliminating the accompanying complications by cooling the blood stream through a newly established venous-venous circuit. This circulation can be obtained easily by connecting silicone tubes from the cubital and saphenous veins, between which a heat cooling apparatus (newly devised with stainless steel tubes), plus a small one way pump is connected. As a result of this procedure, we were able to drop 1 degree of temperature within 6-7 minutes. Eleven clinical cases with this type of anesthesia are discussed and results from the various studies under animal and clinical experiments are mentioned.
