Abstract：Objective To explore the change of platelets after implanting IABP in patients with cardiac surgery and the influence on prognosis.Methods Retrospectively analyze the clinical data of 176 IABP(≥3days) patients from January 2010 to June 2015 in the department of cardiothoracic surgery,Shanghai Jiaotong University School of Medicine.Observe the change of platelets before and after implanting IABP.Analyze the relationship between the thrombocytopenia and patients' prognosis.Results The platelets declined after the application of IABP in 104 patients.Twenty two cases were in the first degree of thrombocytopenia;51 cases were in the second degree of thrombocytopenia;23 cases were in the third degree of thrombocytopenia;and 8 cases were in the fourth degree of thrombocytopenia.A total of 17 patients received platelet transfusion,but no patients occurred serious complications relate to bleeding.At discharge,149 patients survived and recovered,and other 27 patients died or were discharged automatically.Of all alive patients,the platelets returned to normal value at discharge in 141 patients,and other 8 patients still had the first or second degree of thrombocytopenia.Conclusion Thrombocytopenia is one of the complications of using IABP.As long as giving intensive care and timely treatment,patients could get a good prognosis,even if there is a third or fourth degree of thrombocytopenia.At the same time,thrombocytopenia may not be an independent risk factor for in-hospital mortality in patients with IABP,because thrombocytopenia does not cause serious complications relate to bleeding.
