深低温微流量体外循环下治疗动脉导管未闭的体会

Experience of Surgical Treatment in Patients with PDA under Deep Hypothermia and Low-rate Perfusion

本文报告４８例重症ＰＤＡ或合并心内畸形者在深低温微流量体外循环下进行心内直视手术的经验和体会，我们采用深低温，中深度血液稀释法，动脉导管外结扎，压迫或切开肺动脉堵塞未闭动脉导管口，高流量快速降温，使鼻咽温降至１８～２２℃，然后采用微量灌注，直视下缝闭未闭动脉管口，复温同时完成心内其它畸形矫治术，取得了良好的效果。

Fourty-eight patients of PDA combined with pulmonary hypertension or intracardiac defects were operated under deep hypothermia and low flow-rate perfusion.There were 5 deaths in the early stage of this method.It is justified to close the ductal orifice under direct vision in adult patients and in cases combined with pulmonary hypertension or other intracardiac defects with this method.The details of this method were discribed in this paper.
