Open Heart Surgery at Patient’s Own Temperature Without Active Cooling

Le résumé fourni par la source

BACKGROUND: Hypothermia is a method of myocardial protection in cardiac surgery. This protection occurs by decreasing the metabolic demands, however, it creates susceptibility to various problems. In this study, we investigated patients operated on under normothermia (at the patient's own temperature) and hypothermia for postoperative differences. METHODS: The study was conducted between June 2015 and September 2016 with 167 patients. The patients were divided into two groups in accordance with our routine clinical practice: the normothermic group (native temperature goup; intraoperative body temperature ≥ 34°C), and the hypothermic group intraoperative body temperature < 34°C - ≥ 28°C). Preoperative and postoperative data of patients were recorded and the two groups were compared. RESULTS: There was no significant difference between the two groups in terms of cross clamp time, cardiopulmonary bypass time, awakening and extubation times, intensive care unit and hospital stay, drainage, mean serum lactate levels, arrhytmia, all causes infection, renal insufficiency, neurologic complications, myocardial infarction, or mortality (P > .05). Inotrope and transfusion requirements were found to be statistically significantly lower in the normothermic group than the hypothermic group (P < .05). CONCLUSION: Although hypothermia is commonly used in cardiac surgery, it has harmful effects. We believe that cardiac surgery can safely be performed at a patient's own temperature without active cooling to avoid these dangers.
