Effect of monitoring and guiding blood transfusion by TEG on cardiac function and coagulation function
Objective:To analyze the effect of guiding blood transfusion on cardiac function and coagulation function.Methods:A total of 100 patients admitted to cardiac surgery in our hospital from April 2021 to May 2023 were retrospectively included as the study object.According to different guiding blood transfusion methods,they were divided into control group(routine cardiac function and coagulation function monitor guide blood trans-fusion)and research group(thrombelastogram[TEG]monitor guide blood transfusion),of the 50 patients in each group.The TEG parameters of the study group were analyzed before and 24h after transfusion.The parameters were compared between study and control groups,including cardiac function(left ventricular end-diastolic diame-ter[LVEDD],left ventricular end-systolic diameter[LVESD],left ventricular ejection fraction[LVEF])and co-agulation function(prothrombin time[PT],activated partial thromboplastin time[APTT],fibrinogen[FIB],thrombin time[TT]).Results:①The study group performed TEG for 24 h after guiding blood transfusion,lower TEG indicators K,R,a,MA,and higher CI,statistically significant difference(P＜0.05);②There was no sta-tistical significance of LVEDD,LVESD and LVEF between the study group and the control group(P＞0.05).After 24 h of blood transfusion,LVEDD and LVESD in the study group and the control group were both de-creased,LVEF were both increased,there were statistical significance between the groups(P＜0.05).However,LVEDD and LVESD in the study group were lower than those in the control group,the LVEF in the study group was higher than that in the control group,and there were statistically significant between the groups(P＜0.05).③There was no statistical significance of TT,PT,APTT and FIB between the study group and the control group(P＞0.05).After 24 h of blood transfusion,TT,PT and APTT decreased in the study and control groups,FIB both increased,and there was statistically significant difference(P＜0.05).However,TT,PT and APTT in the study group were lower than those in the control group,FIB was higher than that in the control group,and there was statistically significant between the groups(P＜0.05).Conclusion:Compared with the traditional coagulation function monitoring mode,TEG guiding blood transfusion could realize dynamic real-time monitoring,significant-ly improve the cardiac function level and coagulation function of patients,and ensure the safety of blood transfu-sion in patients after extracardiac surgery.
