A study of profound hypothermia by surface cooling.
Profound hypothermia below 20 degrees C achieved by surface cooling using simple ice water bath equipment and deep ether anaesthesia is used with the aid of autonomic nerve blocking agents to obtain cardiac arrest for periods of over one hour for open-heart surgery. Blood levels of ether were between 40.6 mg/dl and 285.7 mg/dl during anaesthesia. No arrhythmia occurred and vital signs were quit...
متن کاملPrevention of chemotherapy-induced hair loss by scalp cooling.
BACKGROUND Chemotherapy-induced temporary hair loss is one of the most common and distressing side-effects of cancer therapy. Scalp cooling to reduce this hair loss is a controversial issue for many doctors and nurses. This may be due to inadequate knowledge. METHODS This review from 53 publications and three personal communications focuses on the efficacy of the treatment, side-effects, poss...
متن کاملInduction and maintenance of mild hypothermia by surface cooling in non-intubated subjects.
Mild induced hypothermia holds promise as an effective therapy for acute ischemic stroke. We developed a novel strategy to rapidly induce and maintain mild hypothermia in unanesthetized, non-intubated subjects as a model for the treatment of acute stroke patients. We induced and maintained mild hypothermia (tympanic membrane temperature 34 degrees C-35 degrees C) for over 5 hours in 10 healthy ...
متن کاملCooling responses in shivering and non-shivering dogs during induced hypothermia.
1. Hypothermia to a temperature of 30 degrees C was induced in both shivering and non-shivering groups of dogs. 2. There was a sustained increase in oxygen consumption in the dogs allowed to shiver and this was up to 300% greater than the oxygen consumption in the relaxed dogs. 3. The increased tissue requirement for oxygen was met both by increased cardiac output and increased oxygen extractio...
متن کاملHypothermia-induced cardioprotection using extended ischemia and early reperfusion cooling.
Optimal timing of therapeutic hypothermia for cardiac ischemia is unknown. Our prior work suggests that ischemia with rapid reperfusion (I/R) in cardiomyocytes can be more damaging than prolonged ischemia alone. Also, these cardiomyocytes demonstrate protein kinase C (PKC) activation and nitric oxide (NO) signaling that confer protection against I/R injury. Thus we hypothesized that hypothermia...
