al arterial and venous cannulae (Fr24/29) in patients for MVP. For all cases, vacuumassist venous drainage (VAVD) and continuous blood gas monitoring devices were used during ECC. RESULTS The ECC time was 98205 (177。)min and aortic crossclamp time was 50125(177。)min. Automatic cardiac resuscitation occurred in 11 patients, while other 2 cases needed external defibrillation. The postoperative intubation time were 717(177。)h, the volume of drainage in 24hs postoperations were 120680 (177。)ml. CONCLUSION The long ECC time and aortic crossclamp time are related to the operation skill . Using VAVD and continuous blood gas monitoring devices and strengthening management during ECC are extremely necessary.
