本文总结我院采用深低温低流量灌注方法纠治小儿先心四联症,与常规方法比较。低流量组转流降温至肛温20℃,流量降至25ml/kg·min,灌注时间15～40分。手术效果满意。该方法不仅具有深低温停循环方法的优点,而且避免了停循环的神经系统并发症,是开展复杂先心纠治术的一种体外循环方法。 This article summarizes our hospital using deep cryogenic flow perfusion method to correct pediatric congenital heart disease, compared with conventional methods. The low-flow group was cooled to rectal temperature 20 ℃, the flow rate dropped to 25ml / kg · min, perfusion time 15 to 40 minutes. Satisfactory results. The method not only has the advantages of deep hypothermic circulatory arrest, but also avoids the circulatory complications of the nervous system. It is an extracorporeal circulation method for complicated correction of heart surgery.
