Title: Management of Cardiopulmonary Bypass on Patients Undergoing Double Valve Replacement Operations
Abstract: Objective To summarize the clinical experience of cardiopulmonary bypass(CPB) in valve replacement operations for rheumatic heart disease.Methods 102 patients,male 47,female 55,aged from 24 to 71 yrs,received valve replacement surgery under hypothermic CPB.The membrane oxygenator was selected.The human albumin,fresh-frozen plasma and artificial colloids were primed and added during CPB if necessary.Myocardial protection performed with blood crystalloids(4:1) hyperkalemia cardioplegia and high perfusion flow 50 ~ 100 ml/kg and high mean arteria pressure 50 ~ 90 mm Hg during CPB.Ultrafiltration technique,suspend red blood cell,and furosemide were used for the raise of Hct during latter CPB.Results CPB time was 69 ~ 254 min(165.7 ± 68.0),aortic cross-clamp time was36 ~ 168 min(99.5 ± 54.9).The incidence of automatic heart resuscitation was 84.4%(86/102).None of the patients died during surgery.All were emerged successfully from CPB.Conclusion Management of cardiopulmonary bypass on rheumatic patients with valve replacement operations should focus on the raise of blood colloids pressure,the myocardial protection,the control of HCT and the correcting the hyperkalemia,hypokalemia,hyponatremia and acidemia during CPB.
