rn目的评价冠脉搭桥术(CABG)前行肝素酶修正的血栓弹力图(hmTEG)检查的临床应用价值。方法 63例冠心病患者,入院时常规凝血功能检查正常,CABG前行hmTEG检查。依据hmTEG检测的凝血指数(CI)分为低凝组34例和正常组29例,比较两组hmTEG参数和相关临床指标。结果低凝组hmTEG检测的参数R值、K值大于正常组,α-角、MA值小于正常组(P“,”Objective To investigate the clinical values of heparinase-modified thromboelastography(hmTEG) before coronary artery bypass grafting(CABG).Methods hmTEG examination was performed in 63 patients before CABG,who were with normal conventional blood coagulation profiles measured on admission.According to the CI value of hmTEG,the patients were divided into two groups of A(34 cases with low coagulation status) and B(29 cases with normal coagulation status).Clinical data and hmTEG values of two groups were compared.ResultsCompared to group B,the R and k values of hmTEG were higher,while α-angle and MA value were lower in group A(P1000 ml,and longer time of tube withdrawal than those in group B(P<0.05).Conclusion hmTEG assay is valuable in evaluating the basal blood coagulation status in patients undergoing CABG.Hypocoagulation status diagnosed by hmTEG before surgery is one of the risk factors for increased intraoperative bleeding and postoperative tube drainage.
