Abstract:
Objective To investigate the effect of creatine phosphate on perioperative myocardial injury caused by living donor liver transplantation(LDLT)in adult patients.Methods Forty ASA Ⅱ -Ⅳ patients(liver function Child-Pugh grade B or C)aged 45-62 yr weighing 47-91 kg undergoing LDLT were randomly divided into 2 groups(n = 20 each): control group(group C)and creatine phosphate group(group CP).In group CP,creatine phosphate 30 mg/kg was injected intravenously at skin incision followed by creatine phosphate infusion at 4 mg· kg- 1 · h- 1 until the end of surgery.In group C,equal volume of normal saline was infused instead of creatine phosphate.HR,MAP,CVP,PCWP,CO and SvO2 were recorded immediately before skin incision,at 5 and 30 min of anhepatic phase,at 5 and 30 min of neohepatic phase and at the end of operation.Blood samples were taken from central vein immediately before skin incision(baseline,T0),at 30 min of anhepatic phase(T1),at 30min of neohepatic phase(T2),at the end of operation(T3)and at 4 and 24 h after operation(T4,5)for determination of serum cardiac troponin I(cTnI)and creatine kinase MB(CK-MB)concentrations and lactate dehydrogenase(LDH)activity.Postoperative adverse events were recorded.Results The serum cTnI and CK-MB concentrations and LDH activity were significantly increased at T2-5 as compared with the baseline value at T0 in both groups(P ＜0.05 or 0.01).MAP and CO were significantly higher from 5 min of neohepatic phase to the end of operation,the serum cTnI and CK-MB concentrations and LDH activity were significantly lower at T2-5,and the incidence of ventricular arrhythmia was significantly lower in group CP than in group C(P ＜ 0.05 or 0.01).Conclusion Creatine phosphate can attenuate perioperative myocardial injury caused by LDLT in adult patients.
