Abstract:
Objective To evaluate the myocardial protective effects of Histidine-TryptophanKetoglutarate (HTK) solution on infants with tetralogy of fallot in cardiac operation through comparison with St.Thomas Ⅱ cardioplegia(STH) and HTK cardioplegia in the operation of tetralogy of fallot.Methods Forty infants with tetralogy of fallot(TOF) were enrolled in this study.Their age ranged from 7 to 35 months,and body mass from 5.3 to 9.5 kg.The infants were randomly divided into HTK (n =20) group and STH (n =20) group who received HTK or STH solution respectively.Then 3 ml blood sample were got at 1,2,4,8,24 and 48 h after the opening of ascending aorta.The serum levels of cardiac troponin Ⅰ(cTnI),creatine kinase(CK) and creatine kinase MB(CK-MB) were measured.Results There was significant difference between two groups in terms of the level of cTnI at different time (F(inner group)=49.94,P＜0.001;F(between group) =10.23,P＜0.001;F (across group) =28.49,P＜0.001),and the level of cTnI in HTK group was lower than that of STH group at 1,2,4,8,24 and 48 h after the opening of ascending aorta (P＜0.05).There was significant difference between two groups in terms of the level of CK at different time (F(inner group) =58.85,P＜0.001;F(between group) =16.43,P＜0.001;F(across group)=18.32,P＜0.001),and the level of CK in HTK group was lower than that of STH group at 1,2,4,8,24 and 48 h after the opening of ascending aorta (P＜0.05).There was significant difference between two groups in terms of the level of CK-MB at different time (F(inner group)=34.51,P ＜0.001;F(between group)=11.03,P＜0.001;F(across group)=10.28,P＜0.001),and the level of CK-MB in HTK group was lower than that of STH group at 1,2,4,8,24 and 48 h after the opening of ascending aorta (P ＜0.05).Conclusion HTK is more valid than STK for improving the ability of anti ischemia of myocardium and cardiac function,reducing arrhythmia and ischemia reperfusion injury on infants with TOF in cardiopulmonary bypass.
