The effects of plateletpheresis on blood conservation during cardiopulmonary bypass

Zhou Xiaoyu,Wang Chengya,Chen Yijiang,et al.First Affiliated Hospital of Nanjing Medical University,Nanjing 210029,China  
Objective To investigate the effects of plateletpheresis on blood conservation following cardiopulmonary bypass.Methods 20 patients undergoing open heart surgery were divided randomly into experiment and control groups.All patients underwent routine CPB.Plateletpheresis was performed in experiment group by using COBE SPECTRA.Other blood conservation approaches were similar in two groups.Results The number of platelets collected in experiment group exceeded 20% of total platelets of every patients.In the experiment group,less transfusion was need.The changes of Hb and Hct at every time point were similar in the two groups.Platelet counts,aggregation,and prothrombin time in the experiment group restored to preoperative levels significantly earlier than in the control group.The chest tube drainage at 2,4,8,and 16 h and the total drainage after operation were significantly lower in the experiment group than those in the control group.Conclusion By protecting platelets from destruction by extracorporeal circulation,plateletpheresis is beneficial to the recovery of haemostatic system.It is a useful blood conservation method.
