Methods Sixty-seven cases of adult patients undergoing valves replacement were randomized into modified ultrafiltration group (n=33) and control group (n=34). Blood gas parameter such as PO2, PCO2 were measured at pre-cardiopulmonary bypass, end CPB, and post MUF (or 20 min post CPB in control group). Ventilatory support time, usage time and amount of vasoactive drug and ejection fraction of left ventricular were also measured in the early period of operation.
