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.
ObjectiveTo compare postoperative analgesic efficacy and motor function recovery between ultrasound guided adductor canal block (ACB) and Femoral nerve block (FNB) in patients after total knee arthroplasty (TKA). MethodsFrom March to April 2014, 40 patients chosen to receive TKA under general anesthesia were randomly allocated to FNB group and ACB group with 20 in each group. Opioids consumption during and after operation, pain score in rest and movement, the force of quadriceps femoris, activity of knee and complications after surgery were recorded. ResultsNo differences were found in opioids consumption during and after operation, pain score in rest and movement after operation. Patients of ACB group were superior to those of FNB group in motor function recovery. At hour 2, 4, 8, 12, 24, and 48 after operation, the force of quadriceps femoris was higher in patients of ACB group than those of FNB group (P<0.05). Activity of knee was higher in patients of ACB group than those of FNB group postoperatively. ConclusionACB and FNB have equal postoperative analgesic effect for TKA patients. But ACB has less influence on the force of quadriceps femoris than FNB. Therefore, patients of ACB group are superior to those of FNB group in motor function recovery, showing better activity of knee and early time of first straight leg raising.
ObjectiveTo provide references for postoperative analgesia treatment for cirrhotic patients with bone fracture. MethodsOne elderly patient with liver cirrhosis and fracture was admitted to our hospital on July 9, 2013. We obtained medical evidences by searching databases and regulated the best treatment after evaluating the patient's comprehensive conditions. And then, the whole treatment strategy was fully implemented. Finally, the consequent results were evaluated. ResultsWe identified 22 relevant articles including one clinical guideline, three cochrane reviews, five systematic reviews, seven small sample randomized controlled trials, one high quality observational study, and five quantitative reviews. We found that opioid analgesics utilization combined with non-opioid analgesics could not only reduce the occurrence of opioid drug adverse reactions, but increase analgesia safety. Cox-2 inhibitors could be used as the first choice of non-opioid drugs due to the less adverse reaction and better analgesic effectiveness. ConclusionFor femur fracture patients with liver cirrhosis, treatment decision based on evidence-based medicine is more scientific, which can ensure maximum benefit for the patients.
Objective To compare the analgesic efficiency and safety of subacromial bursa continued ropivacaine analgesia with patient-controlled intravenous analgesia for arthroscopic rotator cuff repair. Methods A total of 64 patients undergoing rotator cuff repair surgery between October 2013 and February 2015 were randomly divided into the subacromial bursa group (JFX group, 32 cases) and the patient-controlled intravenous analgesia group (JM group, 32 cases). At the end of surgery, a catheter was inserted into the subacromial bursa of the patients in JFX group under arthroscopic visualisation and fixed properly, and analgesia pump was connected after surgery; in JM group, analgesia pump was connected to the vein channel after surgery. The pain Visual Analogue Scale (VAS) (motion and rest) scores 1 hour and 12, 24, 48, 72 hours after surgery, adverse reactions, use of analgesic pump, number of additional analgesia and patients satisfaction were recorded. Results There were no differences between the two groups in the number of additional analgesia, patients satisfaction, additional use of antiemetic drugs, motion and rest VAS scores 1 hour and 12, 72 hours after surgery, and the incidence of moderate-severe pain (VAS≥4) at each time point (P>0.05). The motion and rest VAS scores 24, 48 hours after surgery in JFX group were lower than those in JM group, the analgesia times and the incidence of nausea and vomiting in JFX group were lower than those in JM group, and the differences were statistically significant (P<0.05). Conclusion Efficiency of subacromial bursa infiltration of ropivacaine sustained analgesic is slightly better than that of patient-controlled intravenous analgesia, with lower incidence of adverse reactions.
ObjectivesTo systematically review the efficacy and safety of hydromorphone and morphine in post-cesarean section analgesia.MethodsThe Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, EMbase, CNKI, WanFang Data, VIP and SinoMed databases were electronically searched to identify randomized controlled trials (RCTs) of hydromorphone vs. morphine in the treatment of postoperative analgesia after cesarean section from the inception of the database to December 2017. Two reviewers independently screened literatures, extracted data and assessed risk of bias of the included trials. The meta-analysis was conducted with RevMan 5.3 software.ResultsSeven trials with 586 post-cesarean section patients were included. The results of the meta-analysis showed that, compared with the morphine group, the hydromorphone group had lower 6 h (MD=–0.23, 95%CI –0.38 to –0.08, P=0.003), 12 h (MD=–0.56, 95%CI –1.10 to –0.02, P=0.04), 24 h (MD=–0.37, 95%CI –0.65 to –0.09, P=0.01) and 48 h (MD=–0.41, 95%CI –0.74 to –0.08, P=0.01) postoperative VAS scores the with epidural anesthesia pump (PECA). There was no statistically significant difference of the postoperative Ramsay scores between the two groups. In terms of side effects, the incidence of skin pruritus (RR=0.27, 95%CI 0.09 to 0.81. P=0.02) and vomit (RR=0.15, 95%CI 0.03 to 0.65, P=0.01) of the hydromorphone group were lower than those of the morphine group.ConclusionsThe current evidence demonstrate that, compared with morphine, hydromorphone has better postoperative analgesia performance and less risk of exhibiting skin pruritus and vomit after cesarean section. Considering of the overall quality of evidence and the relatively small pooled sample size, more well-conducted randomized controlled trials are required to verify the above conclusion.
ObjectivesTo systematically evaluate the efficacy and safety of dezocine combine with sufentanil (DS) versus sufentanil (S) for postoperative analgesia.MethodsCNKI, WanFang Data, VIP, PubMed, Wiley Online Library and ScienceDirect databases were searched online to collect randomized controlled trials (RCTs) of DS versus S for postoperative analgesia from January 2011 to July 2017. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by using Stata13.0 software.ResultsA total of 39 RCTs were included. The results of meta-analysis showed that: DS group had higher scores on VAS at 2 h, 6 h, 12 h, 24 h and 48 h points than S group at the dezocine level of 0.2 mg/kg. At the dezocine level of 0.3 mg/kg, there were no significant differences in scores on VAS at 2 h and 4 h. However, DS group had higher scores at 6 h, 12 h, 24 h and 48 h points. At the dezocine level of 10 mg/kg, there were no significant differences in scores on VAS at each time point in both groups. DS group was superior to S group in " excellent rate” and " good rate” of the analgesic satisfaction of patients. For safety, the incidence of postoperative nausea and vomiting of DS group was lower than S group.ConclusionsThe current evidence shows that dezocine combine with sufentanil have more effects of postoperative analgesia than sufentanil alone, and its incidence of adverse reactions is lower. Due to limited quality and quantity of the included studies, more high-quality studies are needed to verify above conclusions.
