Abstract

We have developed a blood cardioplegia delivery system for children. Essential points of a delivery system in pediatric cardiac surgery are (1) a small amount of priming volume of a delivery system, and (2) slow, steady infusion of a cardioplegic solution. We changed a heat exchanger to a smaller one for reduction of priming volume, and changed a roller pump tube to a smaller one for slow, steady infusion. Thus, priming volume of a delivery system has reduced from 180 to 100 ml, and we can infuse a cardioplegic solution at a steady rate less than 10 ml/min. Our clinical experience with this system suggests that this blood cardioplegia delivery system is useful for pediatric cardiac surgery.

摘要

我们已开发出一种用于儿童的血液停搏液输送系统。小儿心脏手术中输送系统的要点包括：（1）输送系统的预充量少；（2）缓慢、稳定地输注停搏液。我们将热交换器换成了更小的型号以减少预充量，并将滚压泵管换成了更小的型号以实现缓慢、稳定的输注。这样，输送系统的预充量从180毫升减少到了100毫升，并且我们能够以小于10毫升/分钟的稳定速率输注停搏液。我们使用该系统的临床经验表明，这种血液停搏液输送系统对小儿心脏手术很有用。
