Ropivacaine wound infiltration:a fast-track approach in patients with hepatocellular carcinoma undergo-ing open hepatectomy / 临床麻醉学杂志

ABSTRACT

Objective To investigate the effectiveness and safety of wound infiltration with rop-ivacaine for postoperative analgesia as a fast-track approach in patients undergoing open hepatectomy. Methods Fifty-two patients with hepatocellular carcinoma,32 males,20 females,aged 18-70 years, scheduled for selective open hepatectomy were enrolled in this trible-blind,randomized,controlled study.Patients were randomized to receive 0.75% ropivacaine (group ROP)or 0.9% normal saline (group NS)wound infiltration before incision closures at a total volume of 10 ml.Numerical rating score (NRS)at 6,12,24 and 48 hours after surgery,length of hospital stay,time to bowel recovery,ambulation and drainage tube extraction were recorded.Side effects, including post-operative liver and renal function,allergic reaction,nausea and vomiting,and wound infection,were also assessed.Results NRS was significantly decreased at 6 [(3.85±1.29)scores vs.(5.30±1.76) scores],12 [(3.38±0.85)scores vs.(5.69 ±1.38)scores]and 24 hours [(3.69 ±0.74)scores vs. (4.42±1.13)scores]after surgery in group ROP compared to group NS (P <0.05).Group ROP al-so showed shorter postoperative hospital stays [(1 7.92±1.97)d vs.(1 9.53±2.42)d],earlier anal exsufflation [(48.07±7.49)h vs.(53.42±10.38)h]and ambulation [(2.34±0.62)d vs.(2.80± 0.84)d](P <0.05).However,there were no significant differences between the two groups in re-garding post-operative liver and renal function.The incidence of nausea and vomiting was 1 5% (4 ca-ses)and 1 9%(5 cases)in group NS and group ROP,respectively.No allergic reactions occurred in either group.Conclusion The present study shows that ropivacaine wound infiltration could effectively release post-operative pain,and could be a safe and effective fast-track approach for patients undergoing open hepatectomy.
