Management of extracorporeal circulation during cardiac surgery in elderly patients with renal dysfunction

Objective:To investigate the management of extracorporeal circulation (ECC)in elderly patients with renal dysfunction during cardiac surgery.Method:Retrospectively analysis was made in the clinical data of 26 elderly patients with renal dysfunction,who underwent cardiac surgery from March 2011to September 2012.The levels of BUN and creatinine were examined before and after operation.Result:There was no death in this study. Compared with preoperative,the levels of BUN and creatinine decreased after 48hours of operation (all P 0.05),but there was no difference after one week.Conclusion:Elderly patients with mild renal dysfunction can got cardiac surgery with ECC and avoid relative complications,when appropriate ECC management be used,such as higher perfusion pressures,higher hematocrit,zero-balanced ultrafiltration and shorter ECC period.
