Title: Management of Cardiopulmonary Bypass on Aged Patients with Valve Replacement Operations
Abstract: OBJECTIVE To summarize the clinical experience of cardiopulmonary bypass(CPB) in valve replacement operations on aged patients.METHODS 28 patients,range from 65 to 73 years old.They were received valve replacement surgery under hypothermic CPB after systemic anesthesia.Myocardial protection performed used blood cardioplegia.High perfusion flow 2.4L~2.8L/(m~2·min)and high mean arteria pressure 60~90mmHg during CPB.All patients were given albumin 20g in CPB prime.Ultrafiltration technique,suspend red blood cell,aprotinin and furosemide were used during CPB.RESULTS CPB time was 45~305min,aortic cross-clamp time was 25~168min.One of the patients died during surgery,the others recovered.CONCLUSION It was effective that myocardial protection performed by anterograde or by combination with anterograde and retrograde cardioplegia perfusion using 4∶1 hyperkalaemic,hypermagnesemic cold blood cardioplegia,or by warm blood anterograde cardioplegia before releasing the aortic cross-clamp.It helped to protect brain,lung and kidney that using albumin,aprotinin and furosemide during CPB.
