The Portex blood warming coil (200/700/000) and water bath (500/111/010) were tested by comparing the body temperatures of two groups of patients undergoing similar operations, but having transfusions of different rate and quantity. The skin and oesophageal temperatures in the massively transfused patients (5-31 units) did not differ significantly from those having minor transfusions (1-5 units). The temperatures were well maintained in both groups. The lowest mean oesophageal temperatures, during the transfusions, were 35.2 +/- 0.2 in the massively transfused patients and 35.4 +/- 0.1 (SEM) in the control group. The warming capacity of the Portex blood warmer was therefore sufficient for our patients. If, however, transfusion rates, higher than those in this study (maximum 96 ml min-1 during the rapid transfusion phase) are needed, a more effective blood warmer may be beneficial.
通过比较两组接受类似手术但输血速度和输血量不同的患者的体温，对Portex血液加温盘管（200/700/000）和水浴箱（500/111/010）进行了测试。大量输血患者（5 - 31单位）的皮肤和食管温度与少量输血患者（1 - 5单位）相比，差异无统计学意义。两组患者的体温均保持良好。输血期间，大量输血患者食管平均最低温度为35.2±0.2，对照组为35.4±0.1（标准误）。因此，Portex血液加温器的加温能力对我们的患者来说是足够的。然而，如果需要高于本研究中的输血速度（快速输血阶段最高96毫升/分钟），则使用更有效的血液加温器可能会有益。
