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.
ABSTRACT
Objective:To investigate the influence of laparoscopic versus open hepatectomy on the stress reaction of patients.MethodsRetrospectively 30 cases who received operation of laparoscopic and open left lateral lobectomy of liver for stones in bile ducts within left lobes of lives were selected form May 2006 to September 2010.The serum level of neutrocytes (N),adrenaline (AD),cortisol (Cor),blood glucose (BG),white blood cell (WBC),Natural killer cell ( NK cell),interleukin-6 (IL-6),C-reactive protein (CRP) were detected preoperatively as well as 24 h,28 h,72 h postoperatively.ResultsAD,Cor reached their peaks after operation,and N,BG,IL-6,CRP reached their peaks in 24 h postoperatively.There were significant difference between O and L groups (P＜0.05).NK cell sank to its lowest level in 24 h postoperatively,and there were no significant difference between the two groups (P＜0.05).ConclusionLaparoscopic and open left lateral lobectomy of liver are two methods curing stones in bile ducts within left lobes of lives,the former process can result in less stress reaction of patients than the latter.
