Because of inadequate rewarming or equilibration of body temperature, patients who undergo cardiac surgery with hypothermia often are still hypothermic after arrival in the intensive care unit. The incidence of residual hypothermia and its hemodynamic effects were assessed in this study. Of 82 adults who underwent cardiac surgery, 41 were normothermic with core temperatures of 35.5 degrees C or higher (mean 36.0 +/- 0.1 degrees C) and 41 were hypothermic with temperatures below 35.5 degrees C (mean 34.9 +/- 0.1 degrees C) on arrival at the intensive care unit (p less than 0.005). Patients with hypothermia had significantly (1.9 +/- 0.1 versus 2.2 +/- 0.1, p less than 0.05) lower cardiac indices. Although not statistically significant, there was a trend toward higher systemic vascular resistance in the patients with hypothermia. The authors conclude that mild residual hypothermia is still common after cardiac surgery and may contribute to the depressed hemodynamic status of these patients.
由于复温不充分或体温未达到平衡，接受低温心脏手术的患者在进入重症监护病房后往往仍处于低温状态。本研究评估了残余低温的发生率及其血流动力学效应。在82例接受心脏手术的成人患者中，41例体温正常，核心温度在35.5摄氏度或更高（平均36.0±0.1摄氏度），41例体温过低，进入重症监护病房时体温低于35.5摄氏度（平均34.9±0.1摄氏度）（p<0.005）。体温过低的患者心脏指数显著降低（1.9±0.1对2.2±0.1，p<0.05）。虽然无统计学意义，但体温过低的患者全身血管阻力有升高趋势。作者得出结论，心脏手术后轻度残余低温仍然常见，可能导致这些患者血流动力学状态低下。
