A simple system is described that recirculates cooling fluid for topical cardiac hypothermia. This disposable system can produce a flow of 1,500 ml/min at 2 degrees to 4 degrees C. The recirculating cooler produced significantly lower myocardial temperatures than a conventional fluid-discard system in 22 patients having coronary operation. This system has been used as part of the technique of hypothermic cardioplegia in more than 600 patients. During various cardiac procedures, septal temperatures were maintained well below 20 degrees C for 60 minutes or more without the need to reinfuse the cardioplegic solution.
描述了一种用于局部心脏低温的冷却流体再循环的简单系统。这种一次性系统能够在2至4摄氏度下产生1500毫升/分钟的流量。在22例接受冠状动脉手术的患者中，该再循环冷却器产生的心肌温度明显低于传统的液体丢弃系统。该系统已在600多名患者中作为低温心脏停搏技术的一部分使用。在各种心脏手术过程中，间隔温度能在60分钟或更长时间内保持远低于20摄氏度，而无需重新注入心脏停搏液。
