ObjectiveTo systematically evaluate the analgesic efficacy of local infiltration analgesia versus femoral nerve block for total knee arthroplasty. MethodsDatabases including PubMed, EMbase, The Cochrane Library (Issue 4, 2016), WanFang Data, CBM, and CNKI were searched to collect randomized controlled trials (RCTs) about the analgesic efficacy of local infiltration analgesia versus femoral nerve block for total knee arthroplasty from inception to April 2016. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. The meta-analysis was conducted using RevMan 5.3 software. ResultsA total of 13 RCTs involving 1 001 patients were included. The results of meta-analysis showed that: There were no significant differences in pain scores at rest (SMD=0.02, 95%CI -0.23 to 0.27, P=0.86), morphine consumption on movement (MD=-1.85, 95%CI -4.67 to 0.97, P=0.20), incidence of post-operative nausea and vomiting (RD=0.02, 95%CI -0.03 to 0.08, P=0.41) and incidence of post-operative knee infection (RD=0.01, 95%CI -0.02 to 0.03, P=0.60) between the two groups, but he local infiltration analgesia group had lower length of stay than the femoral nerve block group with statistical difference (SMD=-0.24, 95%CI -0.41 to -0.07, P=0.005). ConclusionLocal infiltration analgesia provides similar postoperative analgesia after total knee arthroplasty to femoral nerve block. However, due to the limited quantity of the included studies, the above conclusion still need to be verified by more high quality studies.
Objective To analyze the outcome of fast track surgery after intercostal nerve block (INB) during thoracoscopic resection of lung bullae. Methods We recuited 76 patients who accepted thoracoscopic resection of lung bullae from February 2013 to March 2015. They were randomly divided into two groups: an intercostal nerve block and intravenous patient-controlled analgesia (INB+IPCA) group, in which 38 patients (30 males, 8 females, with a mean age of 23.63±4.10 years) received INB intraoperatively and IPCA postoperatively, and a postoperative intravenous patient-controlled analgesia (IPCA) group, in which 38 patients (33 males, 5 females, with a mean age of 24.93±6.34 years) only received IPCA postoperatively. Their general clinical data and the postoperative pain visual analogue scale (VAS) were recorded. Analgesia-associated side effects, rate of the pulmonary infection were observed. Expenses associated with analgesia during hospital were calculated. Results The score of VAS, the incidence of nausea and vomiting, fatigue and other side effects, pulmonary atelectasis and the infection rate in the INB+IPCA group were significantly lower than those in the IPCA group. Postoperative use of analgesic drugs was significantly less than that in the IPCA group. Medical expenses did not significantly increase. Conclusion INB+IPCA is beneficial for fast track surgery after thoracoscopic resection of lung bullae.
Nevus flammeus is a skin disease caused by congenital skin capillary malformation. In recent years, photodynamic therapy (PDT) has been proved to be effective and safe for this disease, but significant pain in the treatment process is the biggest obstacle to the implementation of this therapy. This article reviews the current pain management strategies in PDT. The current pain management methods include topical anesthesia, cold air analgesia, nerve block and others. Topical anesthesia has weak analgesic effect and short duration in PDT. Cold air analgesia is simple and feasible, but there is potential risk of affecting the treatment effect. The analgesic effect of nerve block is accurate, but the application scenario is limited. For nevus flammeus patients who need PDT, individualized analgesia should be selected according to the patient’s age and treatment scenario.
Objective To compare the pain relief and rehabilitation effect of intercostal nerve block and conventional postoperative analgesia in patients undergoing thoracoscopic surgery. Methods China National Repository, Wanfang Database, VIP, China Biomedical Literature Database, Web of Science, Clinicaltrials.gov, Cochrane Library, EMbase and PubMed were searched from establishment of each database to 10 Febraray, 2022. Relevant randomized controlled trials (RCTs) of intercostal nerve block in thoracoscopic surgery were collected, and meta-analysis was conducted after data extraction and quality evaluation of the studies meeting the inclusion criteria. Results A total of 21 RCTs and one semi-randomized study were identified, including 1 542 patients. Performance bias was the main bias risk. Intercostal nerve block had a significant effect on postoperative analgesia in patients undergoing thoracoscopic surgery. The visual analogue scale (VAS) score at 12 h after surgery (MD=–1.45, 95%CI –1.88 to –1.02, P<0.000 01), VAS score at 24 h after surgery (MD=–1.28, 95%CI –1.67 to –0.89, P<0.000 01), and VAS score at 48 h after surgery significantly decreased (MD=–0.90, 95%CI –1.22 to –0.58, P<0.000 01). In exercise or cough state, VAS score at 24 h after surgery (MD=–2.40, 95%CI –2.66 to –2.14, P<0.000 01) and at 48 h after surgery decreased significantly (MD=–1.89, 95%CI –2.09 to –1.69, P<0.000 01). In the intercostal nerve block group, the number of compression of the intravenous analgesic automatic pump on the second day after surgery significantly reduced (SMD=–0.78, 95%CI –1.29 to –0.27, P=0.003). In addition to the analgesic pump, the amount of additional opioids significantly reduced (SMD=–2.05, 95%CI –3.65 to –0.45, P=0.01). Postoperative patient-controlled intravenous analgesia was reduced (SMD=–3.23, 95%CI –6.44 to –0.01, P=0.05). Patient satisfaction was significantly improved (RR=1.31, 95%CI 1.17 to 1.46, P<0.01). Chest tube indwelling time was significantly shortened (SMD=–0.64, 95%CI –0.84 to –0.45, P<0.001). The incidence of analgesia-related adverse reactions was significantly reduced (RR=0.43, 95%CI 0.33 to 0.56, P<0.000 01). Postoperative complications were significantly reduced (RR=0.28, 95%CI 0.18 to 0.44, P<0.000 01). Two studies showed that the length of hospital stay was significantly shortened in the intercostal nerve block group, which was statistically different (P≤0.05), and there was no statistical difference in one report. Conclusion The relief of acute postoperative pain and pain in the movement state is more prominent after intercostal nerve block. Intercostal nerve block is relatively safe and conforms to the concept of enhanced recovery after surgery, which can be extensively utilized in clinical practice.
Objective To compare the analgesic effect, duration and incidence of adverse reactions of liposome bupivacaine (LB) and bupivacaine hydrochloride after intercostal nerve block in single-port thoracoscopic lung surgery. Methods In Department of Thoracic Surgery of the First Affiliated Hospital of Xinxiang Medical University between September 2023 and March 2024, 228 patients who needed to undergo thoracoscopic lung surgery were selected and divided into two groups by random number table method: a group B with bupivacaine hydrochloride (n=118), and a group LB with LB (n=110). Intraoperative intercostal nerve block was performed under endoscopy, and the time of first use of analgesic drugs after surgery, cumulative use of opioids 72 h after surgery, incidence of postoperative nausea and vomiting, length of stay and other indicators were evaluated and recorded. Results Visual analogue scale (VAS) scores at 4 h, 8 h, 12 h, 24 h, 48 h and 72 h in the LB group were significantly lower than those in the group B (P<0.05). The total number of activities within 48 h after surgery in the group B was significantly lower than that in the LB group (P<0.05), and the postoperative hospitalization stay in the LB group was shorter than that in the group B, but the difference was not statistically significant. There was no statistical difference between the two groups in postoperative adverse reactions. Conclusion Intercostal nerve block with LB during single-port thoracoscopic lung surgery can significantly reduce postoperative pain, improve quality of life, and promote recovery of the patients. It is worthy of clinical application.
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 investigate the efficacy of sequential treatment with adductor canal nerve block (ACNB) and cyclooxygenase 2 (COX-2) selective inhibitor (parecoxib and celecoxib) after primary total knee arthroplasty (TKA). MethodsBetween January 2015 and December 2015, 90 osteoarthritis patients who met the inclusion criteria were treated, and randomly divided into 3 groups:ACNB+COX-2 group (group A, n=30), COX-2 group (group B, n=30), and control group (group C, n=30). There was no significant difference in gender, age, body mass index, side, and osteoarthritis duration between groups (P > 0.05), and the data were comparable. ACNB was used in group A at the end of TKA. Intravenous injection of parecoxib (40 mg per 12 hours) was administrated at the first three postoperative days, and followed by oral celecoxib (200 mg per 12 hours) until 6 weeks after operation in groups A and B; while placebo was given at the same time point in group C. Oral tramadol or intravenous morphine, as remedial measures, were introduced when patients had a visual analogue scale (VAS) score more than 4. The following indicators were compared between groups:the operative time, drainage volume at 24 hours after operation, length of hospital stay, and incidence of side effect; VAS pain scores, morphine consumption, range of motion (ROM) of the knee joint, and inflammatory cytokines levels at pre-operation and at 1 day, 2 days, 3 days, 1 week, 2 weeks, 4 weeks, and 6 weeks after operation; morphine consumption within first 24 hours and at 24 hours to 6 weeks after operation; the American Hospital for Special Surgery (HSS) score at 1, 2, 4, and 6 weeks after operation; and the serum coagulation parameters at pre-operation, and at 1, 3, and 14 days after operation. ResultsThe length of hospital stay was significantly shorter and the incidence of postoperative nausea and vomiting was significantly lower in groups A and B than group C (P < 0.05). The VAS scores at rest (VASR) of groups A and B were significantly lower than that of group C at 1, 2, and 3 days after operation (P < 0.05); difference in the VAS scores at walking (VASW) was significant between groups at 1 day after operation (P < 0.05), and group A had the lowest VASW; and the VASW of groups A and B were significantly lower than that of group C at 2 and 3 days and at 1, 2, 4, and 6 weeks after operation (P < 0.05). The difference in morphine consumption was significant between groups within the first 24 hours after operation (P < 0.05), and group A exhibited the lowest consumption; and the morphine consumption in groups A and B was significantly lower than that in group C at 24 hours to 6 weeks after operation (P < 0.05). Significant difference was found in HSS scores between groups at 1, 2, 4, and 6 weeks after operation, and group A showed the highest score (P < 0.05). At 1 and 2 days after operation, group A showed the highest ROM (P < 0.05), and ROM of groups A and B was significantly higher that of group C at 3 days, 1 week, 2 weeks, 4 weeks, and 6 weeks after operation (P < 0.05). Groups A and B were significantly lower than group C in the serum erythrocyte sedimentation rate at 2 days, 3 days, 1 week, 2 weeks, 4 weeks, and 6 weeks, in C-reactive protein levels at 1, 2, and 3 days, in interleukin 6 (IL-6) and TNF-α levels at 1 day to 6 weeks, and in IL-8 level at 2 and 3 days (P < 0.05). The drainage volume within the first 24 hours and the serum coagulation parameters within the 2 weeks after operation showed no significant difference between groups (P > 0.05). ConclusionSequential treatment with ACNB and COX-2 selective inhibitor is a safe and effective approach for postoperative pain management after primary TKA, and it can alleviate postoperative pain, promote the joint function recovery, and reduce the risk of adverse reactions.
Objectives To overview the systematic reviews/meta-analyses of safety of femoral nerve block (FNB) used as a postoperative analgesic technique in patients undergoing total knee arthroplasty (TKA). Methods We searched databases including The Cochrane Library, PubMed, EMbase, CNKI, WanFang Data, and VIP from inception to July, 2016. Two reviewers independently screened literature, extracted data and used AMSTAR to evaluate the methodological quality of the included studies. The major indexes used to evaluate the safety of FNB were the incidence rates of symptoms including nausea, vomiting, sedation, retention of urine, dizziness, pruritus, hypotension, falls, nenous thromboembolism and deep infection. Results A total of 12 systematic reviews/meta-analyses were included.They assessed the safety of FNB compared with local infiltration analgesia (LIA), periarticular multimodal drug injection (PMDI), epidural analgesia (EA), patient-controlled intravenous analgesia of opioids (PCA) and adductor canal block (ACB), respectively. The methodological quality of included studies were medium, with the scores between 3 to 10. The results of overview indicated that: FNB had lower incidence rates of nausea and vomiting compared with EA and PCA, but had higher than ACB. FNB had lower incidence rates of sedation and retention of urine compared with EA and PCA. FNB had lower incidence rates of dizziness compared with EA and PCA, and lower incidence rate of hypotension compared with EA. Conclusion Current evidence suggests that FNB is safer than EA and PCA. Due to the limited quantity and quality of the included studies, the above conclusions are needed to be verified by more high-quality studies.
ObjectiveTo evaluate the clinical efficacy and safety of the inguinal approach versus classical pubic approach for obturator nerve block (ONB) in transurethral resection of bladder tumors (TUR-BT).MethodsDatabases including PubMed, The Cochrane Library, EMbase, Web of Science, WanFang Data, CNKI and VIP databases were electronically searched to identify randomized controlled trials using ONB in TUR-BT from inception to May 2020. Two reviewers independently screened literature, extracted data, and assessed risk bias of included studies. Meta-analysis was performed by using Stata 14.2 software.ResultsA total of 7 studies involving 474 patients were included. The meta-analysis results showed that there was no significant difference between inguinal approach and pubic approach in terms of the ONB success rate (RR=1.06, 95%CI 0.96 to 1.17, P=0.23), while the one-time success rate of puncture of inguinal approach was higher than that of pubic approach (RR=1.47, 95%CI 1.01 to 2.15, P=0.04). Compared with the pubic approach, the overall complications of inguinal approach were lower (RR=0.24, 95%CI 0.08 to 0.71, P=0.01). However, no significant difference was found between the two groups in terms of subcutaneous hematoma (RR=0.46, 95%CI 0.08 to 2.66, P=0.38).ConclusionsThe current evidence indicates that the success rate of one puncture of inguinal approach is higher than that of pubic approach, and the overall complications of the inguinal approach are much lower than that of the pubic approach. However, the above conclusions are still required to be verified through more high-quality studies due to the limited quantity and quality of included studies.
Objective To compare the analgesia effect and clinical rehabilitation between continuous adductor canal block (ACB) and single shot ACB in total knee arthroplasty (TKA)． Methods Between October 2016 and February 2017, 60 patients with severe knee osteoarthritis undergoing primary unilateral TKA were prospectively recruited in the study. All the patients were randomly allocated into 2 groups and received ultrasound-guided continuous ACB (group A, n=30) or single shot ACB (group B, n=30), respectively. There was no significant difference in gender, age, body mass index, nationality, American Society of Anesthesiology (ASA) grading, and preoperative knee range of motion and quadriceps strength between 2 groups (P>0.05). After operation, the tourniquet time, postoperative drainage volume, hospitalization time, and adverse events in 2 groups were recorded. Visual analogue scale (VAS) scores at rest and during activity, the quadriceps strength, the knee range of motion, and the time of 90° knee flexion in 2 groups were also recorded and compared. Results There was no significant difference in tourniquet time, postoperative drainage volume, and incidence of adverse events between 2 groups (P>0.05). But the hospitalization time was significant shorter in group A than in group B (P<0.05). VAS scores at rest and during activity were lower in group A than in group B, with significant differences in VAS score at rest after 12 hours and in VAS score during activity after 8 hours between 2 groups (P<0.05). The quadriceps strength was higher in group A than in group B, with significant difference at 24, 48, and 72 hours (P<0.05). The knee range of motion was significantly better in group A than in group B at 24, 48, 72 hours and on discharge (P<0.05). The time of 90° knee flexion was significantly shorter in group A than in group B (t=–2.951, P=0.016). There were 4 patients in group A and 7 patients in group B requiring meperidine hydrochloride (50 mg/time) within 24 hours, and 3 patients in group A and 7 patients in group B at 24 to 48 hours, and 1 patient in group A and 3 patients in group B at 48 to 72 hours. Effusion in the catheter site occurred in 2 cases of group A, but no catheter extrusion occurred. Conclusion Continuous ACB is superior in analgesia both at rest and during activity and opioid consumption compared with single shot ACB after TKA. And the quadriceps strength could be reserved better in continuous ACB group, which can perform benefits in early rehabilitation.
