RESUMO
Objective To investigate the influence of pain on liver function recovery after hepatectomy Methods Clinical data of 257 patients with primary hepatocellular carcinoma were analyzed retrospectively. The patients were divided into effective analgesia group(NRS ≤ 3 points)and ineffective analgesia group(NRS > 3 points)according to the digital hierarchy(NRS). The serum liver function indexes including ALT,AST,TBiL, ALB and PT were compared in 2 groups. Results There was no significant difference in preoperative liver function between 2 groups but the levels of ALT ,AST ,PT and TBIL at 1st ,3rd ,5th and 7th days postoperatively were lower in effective analgesia group than those in ineffective analgesic group after surgery(P<0.05). The incidence of the delay of liver function was lower in effective analgesia group than that in ineffective analgesic group. Conclusion Effective analgesic treatment can reduce liver damage and accelerate liver function recovery.
