Methods One hundred and twenty patients aged between 18 and 65 years old with an ASA score from Ⅰ to Ⅱ who underwent elective laparoscopic cholecystectomy from June 2010 to April 2011 comprised this study. The patients were randomly divided into four groups with 30 in each group. Patients in group A had an infusion of 0.75% ropivacaine (10 mL) at the beginning of LC plus tramadol (2 mg/kg) intravenous injection at the end. Group B patients had an infusion of normal saline 0.9% (10 mL) at the beginning of LC plus tramadol (2 mg/kg) intravenous injection at the end. Patients in group C had an infusion of 0.75% ropivacaine (10 mL) at the beginning of LC plus normal saline 0.9% (10 mL) intravenous injection at the end. Group D (control group) patients had neither ropivacaine nor tramadol infusion. Pain in the right upper abdomen, right shoulder tip and abdominal incision were assessed at hour 2, 4, 6, 12, and 24 postoperatively using a visual analog score (VAS). Results Right upper abdomen and right shoulder tip pain VAS comparison: significantly lower pain scores were observed in group A and B (Plt;0.05) than in group D (Pgt;0.05). Group A had significantly lower pain scores than group B (Plt;0.05) and C (Plt;0.01) at postoperative hours 2, 4, 6, 12, and 24. Abdominal incision pain VAS comparison: VAS scores were significantly lower in group A, B and C than in group D (Plt;0.05). Group A had significantly lower pain scores than group B (Plt;0.05) and C (Plt;0.01) at postoperative hours 2, 4, 6, 12, and 24. Conclusion Preincisional ropivacaine at the beginning of LC combined with tramadol intravenous injection at the end can effectively alleviate postoperative pain after laparoscopic cholecystectomy.
Objective To evaluate the effectiveness and safety of ropivacaine in spinal anesthesia. Methods We searched PubMed (1999 to 2008), OVID (1999 to 2008), EBSCO (1999 to 2008), The Cochrane Library (2000 to 2008), and CNKI (1999 to 2008) databases to identify randomized controlled trials (RCTs) that compared ropivacaine and bupivacaine for spinal anesthesia. The quality of the included RCTs was evaluated by two reviewers independently, and meta-analysis was performed by RevMan 5.0 software. Results Six RCTs were included. The methodological quality of them were all poor. Among the six RCTs, 215 patients received ropivacaine and 215 received bupivacaine. The results of meta-analyses showed that the motor-block time to complete block of ropivacaine was significantly shorter than that of bupivacaine (WMD=2.18 min, 95%CI 0.32 to 4.03, P=0.02). The motor-block time to complete recovery of ropivacaine was significantly shorter than that of bupivacaine for cesarean delivery in spinal anesthesia (SMD= – 1.82, 95%CI – 3.05 to – 0.59, P=0.004). The incidence rate of hypotension and bradycardia in spinal anestheisa with ropivacaine was lower than that with bupivacaine (OR=0.49, 95%CI 0.31 to 0.80, P=0.004; OR=0.40, 95%CI 0.03 to 4.99, P=0.47). Conclusion Equivalent doses of ropivacaine and bupivacaine provide similar analgesia in spinal anesthesia for cesarean delivery. However, haemodynamics in spinal anesthesia with ropivacaine fluctuate lightlier than with bupivacaine. Ropivacaine is suitable for spinal anesthesia in low-abdominal operations.
Objective To evaluate the analgesic effect of intra-articular ropivacaine with lidocaine. Methods A double-blind randomized controlled trial was conducted. Ninety patients receiving selective knee arthroscopy were randomized into three groups of 30 patients. At the end of the operation, before the release of the tourniquet, an intra-articular injection was administered to each patient through arthroscope, in accordance with their random allocation: 0.9% normal saline (normal saline group); 100 mg ropivacaine (ropivacaine alone group) and 100 mg ropivacaine and 100 mg 2% lidocaine (ropivacaine with lidocaine group). Pain intensity was assessed after the operation using the 100-mm visual-analog scale (VAS), and the amount of supplemental analgesics used within the following 24 hours were recorded. Results The VAS scores of 2 hours postoperatively at rest, and 1, 2, 4, and 8 hours postoperatively at motion, were significantly higher in the normal saline group than in ropivacaine alone group (Plt;0.05). The VAS scores 0.5, 1 and 2 hours postoperatively at rest, and at the awaking moment, 0.5, 1, 4, 8, and 24 hours postoperatively at motion, were significantly higher in the normal saline group than in ropivacaine with lidocaine group (Plt;0.05). Conclusion Intra-articular ropivacaine can reduce a patient’s pain after operation. The combination of lidocaine with intra-articular ropivacaine can reduce the patient’s pain severity immediately after the operation and achieve an early analgesic effect.
【摘要】 目的 比较单次股神经阻滞和关节腔内单次注射罗哌卡因对膝关节镜检术后镇痛效果，为临床应用提供试验依据。 方法 2009年1月-2010年7月，选择美国麻醉医师协会（ASA）Ⅰ～Ⅱ级、年龄18~65岁、拟行择期单侧下肢膝关节镜手术患者180例，随机分为股神经阻滞组和关节腔内用药组，每组90例，分别于术前1 h行股神经阻滞（0.15%罗哌卡因20 mL）和手术结束时在膝关节腔内注入0.6%罗哌卡因20 mL。于术后4、8、24 h采用视觉模拟评分法（visual analog scale，VAS）行静止和运动时疼痛评分，记录术后患者满意度、不良反应发生率，术后使用镇痛药物情况。 结果 关节腔内用药组术后镇痛药物使用率（41.11%）明显高于股神经阻滞组（20.00%）（Plt;0.005）。两组患者术后24 h静止时及术后8、24 h运动时的VAS评分关节腔内用药组均明显高于股神经阻滞组（Plt;0.001），其余各时点差异无统计学意义（Pgt;0.05）。 结论 股神经阻滞可提供更加有效的术后镇痛效果，并且用药量小，安全系数高，值得临床推广。【Abstract】 Objective To compare the effect of single-injection femoral nerve block and local anesthetic intraarticular injection for analgesia after knee arthroscopy, in order to provide the experimental base for clinical application. Methods From January 2009 to July 2010, 180 American Society of Anesthesiologists (ASA) physical status I-II patients, aged from 18 to 65 years old, and scheduled for elective single knee arthroscopy were randomly divided into two groups: femoral nerve block group and local anesthetic intraarticular injection group with 90 patients in each group. For the patients in the former group, 20 mL of 0.15% ropivacaine was injected 1 hour before operation. For the latter group, 20 mL of 0.6% ropivacaine was injected into the articular cavity after operation. Pain intension scores at rest and in motion were measured 4, 8, and 24 hours after operation by visual analog scale (VAS). The degree of patients’ satisfaction, adverse reaction incidence rate and information of taking pain-killers were also recorded. Results The rate of using pain-killers in the intraarticular injection group (41.11%) was dramatically higher than the femoral nerve block group (20.00%) (Plt;0.005). The VAS scores of patients in the intraarticular injection group at rest 24 hours after operation and in motion 8 hours and 24 hours after operation were significantly higher than the femoral nerve block group (Plt;0.001), while there was no significant difference at other points between the two groups. Conclusions Femoral nerve block is more efficient for analgesia after knee arthroscopy compared with local anesthetic intraarticular injection. It is a safe procedure requiring only a relatively small dose of medicine, and is worth being popularized.

Methods Data was collected from April 2009 to November 2009. Sixty patients after cesarean section under continuous epidural anesthesia were randomly divided into three different groups.Group A was given sufentanil 0.3 μg/mL and 0.125% ropivacaine for PCEA, group B was given sufentanil 0.4 μg/mL and 0.125% ropivacaine, group C was given sufentanil 0.5 μg/mL and 0.125% ropivacaine. The analgesia effects were evaluated by the visual analogue scales (VAS). Side effects were also recorded. Results The VAS scores were significantly the highest in group A than that in group B and group C, the VAS scores in group B were higher than that in group C (Plt;0.05). The incidence of side effects, such as postoperative nausea and vomiting, lethargy, and pruritus, was not significant among the three groups (Pgt;0.05). Conclusion 0.5 μg/ mL sufentanil and 0.125% ropivacaine recommended for PCEA with background 4 mL/h is safe and effective for patients after cesarean section.
