[Application of vacuum-assisted venous drainage technology in minimally invasive cardiac surgery].

OBJECTIVE

To summarize the method and experience of cardiopulmonary bypass (CPB) with vacuum-assisted venous drainage technology (VAVD) in the minimally invasive cardiac surgery (MICS).

METHODS

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.

RESULTS

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).

CONCLUSION

The use of VAVD in the MICS can increase the vena cava drainage effectively, and ensure the surgery safe and successful.
