Unusual excessive sweating and hypothermia during hysterectomy under general anesthesia: A case report

ABSTRACT

A 78-year-old female patient was undergone general anesthesia for total abdominal hysterectomy with bilateral salpingo-oopherectomy. Arterial blood pressure dropped 20 minutes after beginning of the surgery when uterine manipulation was started. From then, excessive sweating was found in the face and whole body and core temperature decreased to 34.3degrees C. Sweating and low body temperature were sustained despite of various aggressive warming efforts. Anticholinergic medication immediately put an end to an hour of excessive sweating and prevented further body temperature decline. Several possibilities of excessive sweating were discussed in this case: uterine manipulation during the light plane of general anesthesia, age related autonomic changes, use of intraoperative opioid and antihypertensive medications.
