Title: Management of cardiopulmonary bypass for open heart surgery with beating heart
Abstract: Objective To discuss the management methods of cardiopulmonary bypass(CPB) for patients underwent open heart surgery with beating heart.Methods The CPB management methods for 2 290 patients underwent open heart surgery with beating heart were summed-up.The left heart venting was established during the surgery and integrated sequetial de-airing procedure was conducted at the end of the surgery.The temperature of nasopharynx was maintained between 30~32 ℃,hematocrit was kept between 20%~30% and the flow was controlled between 2.4~3.2 L·m-1·min-2.α-stat blood gas strategies were applied,meanwhile conventional ultrafiltration or modified ultrafiltration was performed according to the condition.Results CPB went sucessful in all cases,the CPB time was 22~179 minutes.Ventricular fibrillation was occurred in 256 cases and 181 cases experienced automatic recovery to beating.There were 22 cases died including 15 cases of complex congenital heart disease and 7 cases of severe valvular heart disease.No complication correlated with perfusion was oberved.Conclusion Open heart sugery with beating heart under mild hypothermia by cardiopulmonary bypass is safe and feasible,meanwhile it is easy for management and it can effectively prevent ischemia reperfusion injury.
