Abstract:
Objective To compare the severity of hepatic ischemidreperfusion(I/R)injury caused by partial hepatectomy performed under propofol-remifentanil and isoflurane-fentanyl anesthesia.Methods Thirty ASA Ⅰ or Ⅱ patients aged 41-64 yr weighing 58-86 kg undergoing elective partial hepatectomy were randomly divided into 2 groups(n=15 each):propefol-remifentanil group(PR)and isoflurane-fentanyl group(IF).Anesthesia was induced with midazolam,fentanyl,etomidate and vecuronium.The patients were mechanically ventilated after tracheal intubation.Anesthesia was maintained with TCI of propofol(Cp=3.5μg/ml)and remifentanil(Cp=4.2 ng/ml)in group PR or 1.5%-2.5% isoflurane and intermittent iv boluses of fentanyl in group IF.Muscle relaxation was maintained with intermittent iv boluses of vecuronium in both groups.Blood samples were taken before occlusion of hepatic portal(T1)immediately(T2)and 30,60 min after release of portal occlusion(T3,4)and 1 d after operation(T5),for determination of sernm levels of ALT,AST,γ-GGT,LDH,TBIL,T-SOD and MDA.Specimens were obtained from the liver left intact after partial hepatectomy for ultrastructural examination with electron microscope.ResultsSerum levels of ALT at T5,γ-GGT at T3,4,and MDA at T4,5 were significandy lower while T-SOD at T5 were significantly higher in group PR than in group IF.Electron microscopic examination showed that tissue damages were significantly aRenuated in PR group as compared with IF group.Conclusion Propofol-remifentanil anesthesia can to some extent pmtect the liver against I/R injury during partial hepatectomy by reducing oxygen free radicals.
