To summarize the method and experience of cardiopulmonary bypass (CPB) with vacuum-assisted venous drainage technology (VAVD) in the minimally invasive cardiac surgery (MICS).
35 cases of patients undergoing MICS were achieved femoral arterial cannula and femoral venous cannula. During the course of the CPB, we used the VAVD technology. At the same time, we selected 35 cases as control group.The time of the CPB, mechanical ventilation and ICU, and the amount of the urine, blood products, and chest drainage were recorded.
The time of mechanical ventilation and ICU staying, the volume of the blood products and the volume drainage within 48 h postoperatively in the MICS group were significantly shorter and less than that in control group (P < 0.05).
The use of VAVD in the MICS can increase the vena cava drainage effectively, and ensure the surgery safe and successful.
总结在微创心脏手术（MICS）中应用真空辅助静脉引流技术（VAVD）进行体外循环（CPB）的方法及经验。
35例行MICS的患者采用股动脉插管和股静脉插管。在CPB过程中，应用VAVD技术。同时选取35例患者作为对照组。记录CPB时间、机械通气时间、ICU停留时间以及尿量、血制品用量和胸腔引流量。
MICS组的机械通气时间、ICU停留时间、术后48小时内血制品用量及引流量均明显短于和少于对照组（P<0.05）。
在MICS中应用VAVD可有效增加腔静脉引流，确保手术安全成功。
