Application of Thromboelastograph Monitoring in Perioperative Blood Transfusion in Patients Undergoing OPCABG
Objective To investigate the application of TEG monitoring in perioperative blood transfusion in patients undergoing OPCABG.Methods A total of 122 patients who were admitted to our hospital from April 2019 to April 2022 for OPCABG surgery requiring blood transfusion during the perioperative period were selected and divided into the control group and the observation group according to the random number table method,with 61 cases in each group.The control group underwent routine blood coagulation monitoring,and the observation group underwent TEG monitoring.The use of blood products,coagulation status,perioperative infusion volume,blood loss and blood transfusion volume,perioperative drug use and clinical outcomes were compared between the two groups.Results The levels of suspended red blood cells(RBC),fresh frozen plasma(FFP),mechanically collected platelets and cryoprecipitate coagulation factors in the observation group were lower than those in the control group(P all＜0.05).Compared with the same group before operation,the levels of serum platelet count(PLT),hematocrit,fibrinogen(FIB)and hemoglobin in the two groups decreased 1 h after operation,while activated partial thromboplastin time(APTT)was prolonged.The input of PLT and FFP in the observation group was less than that in the control group(P all＜0.05).However,compared with the control group before operation and 1 h after operation,there was no significant difference in blood loss,transfusion,autologous blood input,RBC input,tranexamic acid,protamine,FIB usage,intensive care unit(ICU)stay time,tracheal intubation time,hospitalization time,reoperation rate and mortality rate between the control group and the observation group(Pall＞0.05).Conclusion TEG monitoring can effectively control the use of blood products in patients with OPCABG,reduce the blood transfusion volume of patients,and has no significant impact on the bleeding volume and prognosis of patients.
