In previous publications on this subject,2,3 we have reported the use of intragastric cooling as an adjunct to external blanket refrigeration in the induction of general hypothermia as used at the Northwestern University Medical Center and, more recently, at the West Virginia University Medical Center. The purpose of this paper is to report the continued successful use of an internal means of temperature control as well as to describe a refinement of our original cooling device.
Thirty-six surgical patients were cooled and rewarmed in this study. A summary of pertinent data is given in Table 1. Twenty-six craniotomies were performed for meningiomas, intracranial aneurysms, subdural hematomas, an arteriovenous fistula, a pituitary tumor, and a fibrosarcoma. The seven surgical heart lesions included: aortic stenosis, atrial septal defect, and ventricular septal defect. A carotid endarterectomy, renal endarterectomy, and a thoracic aneurysm were the three vascular disorders operated upon.
