ObjectiveTo explore the safety and efficacy of thoracoscopic guided thoracic paravertebral block (TPVB) in resection of lung, and to provide strategies for enhanced recovery after surgery of lung surgery. MethodsA total of 180 patients with thoracoscopic surgery of lung (including sublobar resection and lobectomy) hospitalized between May 2021 and June 2023 were included. There were 108 females and 72 males with an average age of (62.15±7.36) years. Patients were divided into 3 groups. Patients received subcutaneous injection of ropivacaine (concentration: 0.375%, dose: 2 mg/kg) on peripheral incision at chest closing were allocated into a group A. Patients received ultrasound-guided injection of ropivacaine (concentration: 0.375%, dose: 2 mg/kg) at the TPVB point after chest closing into a group B. Patients received thoracoscopic guided injection of ropivacaine (concentration: 0.375%, dose: 2 mg/kg) before chest closing at the TPVB point into a group C. The baseline data of each group were compared, and the effectiveness outcomes included perioperative adverse drug reactions, pain scores, postoperative analgesic drug use and postoperative hospital stay were compared among the 3 groups. ResultsThere were no statistical differences in the baseline data of three groups, including age, weight, gender, incidence of previous underlying diseases, operation time, number of surgical incisions, number of drainage tubes inserted, and dosage of sufentanil or propofol used during surgery (P>0.05). There were no adverse anesthesia events in the 3 groups during the operation, the frequency of self-controlled intravenous analgesia pump, the VAS score, the incidence of adverse reactions, and the rate of postoperative analgesic drug use in group C was less or lower than the other two groups (P<0.05). The hospital stay in the group C and group B were lower than that in the group A (P<0.05). ConclusionThoracoscopic guided TPVB can reduce postoperative pain without increasing postoperative side effects, which had accelerated the enhanced recovery after surgery of lung.
ObjectiveTo summarize the early postoperative pain management strategies for anterior cruciate ligament reconstruction (ACLR), and to select a reasonable and effective pain management plan to promote functional rehabilitation after ACLR. MethodsThe literature about the early postoperative pain management strategies of ACLR both domestically and internationally in recent years was extensiverly reviewed, and the effects of improving postoperative pain were reviewed. ResultsCurrently, physical therapy and oral medication have advantages such as economy and simplicity, but the effect of improving postoperative pain is not satisfactory, often requires a combination of intravenous injection or intravenous pump, which is also a common way to relieve pain. However, in order to meet the analgesic needs of patients, the amount of analgesic drugs used is often large, which increases the incidence of various adverse reactions. Local infiltration analgesia (LIA), including periarticular or intra-articular injection of drugs, can significantly improve the early postoperative pain of ACLR, and achieve similar postoperative effectiveness as nerve block. LIA can be used as an analgesic technique instead of nerve block, and avoid the corresponding weakness of innervated muscles caused by nerve block, which increases the risk of postoperative falls. Many studies have confirmed that LIA can alleviate postoperative early pain in ACLR, especially the analgesic effects of periarticular injection are more satisfactory. It can also avoid the risk of cartilage damage caused by intra-articular injection. However, the postoperative analgesic effect and timeliness still need to be improved. It is possible to consider combining multimodal mixed drug LIA (combined with intra-articular and periarticular) with other pain intervention methods to exert a synergistic effect, in order to avoid the side effects and risks brought by single drugs or single administration route. LIA is expected to become one of the most common methods for relieving postoperative early pain in ACLR. ConclusionEarly pain after arthroscopic ACLR still affects the further functional activities of patients, and all kinds of analgesic methods can achieve certain effectiveness, but there is no unified standard at present, and the advantages and disadvantages of various analgesic methods need further research.
Objective To study the neural mechanism of hypotension or shock state in acute cholangitis in severe type (ACST) and its value of clinical application. Methods A technique of blocking abdominal splanchnic nervi via right adipose capsule of kidney was carried out on 28 patients by injecting 1% lidocaine before urgent operation. Results After blocking the relevant nervi, hypotension or shock state in 23 patients were improved significantly (Ｐ＜0.05). The death rate was lower (14.3%) after having performed biliary decompressions with laparotomy. Conclusion Patients′ hypotension or shock state at the early phase of ACST is the result of neural reflex in which the splanchnic nervi is its afferent pathway. Blocking the relevant nervi before urgent operation, the valuable opportunity of emergency treatment can be obtainded and the complication and death rate are reduced significantly.
ObjectiveTo investigate the efficacy of stellate ganglion block (SGB) on postoperative palpebral edema in patients undergoing intracranial aneurysm surgery. MethodsSixty patients who were scheduled to undergo intracranial aneurysm surgery between September 2012 and Novermber 2014 were recruited, and were assigned into 2 groups randomly with 30 in each:SGB group and control group. Patients in SGB group were administered SGB by injecting 0.3% ropivacaine on the operative side under the ultrasound guidance after surgery completed, while patients in the control group received injection of saline on the operative side under the ultrasound guidance. Incidence of postoperative palpebral edema at hour 24, 48, and 72 after surgery were measured. Numerical rating scale (NRS) was used to detect the severity of uncomfortable symptoms for palpebral swelling during rest state. The severity of palpebral edema was evaluated with continuous rating scale (0-5, 0 indicated normal palpebral, and higher score indicated more serious palpebral edema). Complications related with SGB were recorded. ResultsThe overall incidence of palpebral edema at hour 24 after surgery in SGB group was lower than that in the control group (P<0.05). There was no statistically significant difference in the overall incidence of palpebral edema at hour 48 and 72 after surgery between the two groups (P>0.05). The palpebral edema rating scores of the SGB group at hour 24 after surgery were lower than those of the control group (P<0.01).The incidence of palpebral edema which was scored 3 or more at hour 24 and 48 after surgery in SGB group was lower than that in the control group (P<0.05). No statistically significant difference was found in the incidence of palpebral edema which was scored 3 or more at hour 72 after surgery between the two groups (P>0.05). No complication related with SGB was found. ConclusionSGB can safely reduce the incidence of postoperative palpebral edema in patients undergoing intracranial aneurysm surgery, and reduce the severity of palpebral edema.
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.
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 overview the systematic reviews/meta-analyses of efficacy of FNB used as a postoperative analgesic technique among patients undergoing TKR. Methods We electronically searched databases including The Cochrane Library, PubMed, EMbase, CNKI, WanFang Data and VIP from inception to July, 2016. Two reviewers independently screened literature and extracted data. AMSTAR tool was used to assess the methodological quality of included studies. The primary outcome was pain scores and the consumption of opoid medicine to evaluate the effectiveness of FNB. Results A total of 16 systematic reviews/meta-analyses were included, involving the FNBvs. LIA, PMDI, EA, PCA and ACB, respectively. The results of quality assessment indicated medium scores with 3 to 9 scores. The overviews’ results showed that: at rest, FNB was not superior to LIA at 6h after TKR; it was superior to PMDI at 12h after TKR; it was also superior to PCA and LIA, but not superior to ACB at 24h after TKR. On movement, FNB was superior to PCA and LIA at 24h after TKR; it was also superior to PCA at 48h after TKR. As to the consumption of opoid medicine, the consumption in FNB group was more than LIA group at 12h after TKR. In addition, the consumption in FNB group was less than PCA and LIA at 24h after TKR, and it was also less than PCA and ACB at 48h. The satisfaction of patients who received FNB was better than ACB, EA and PCA. Conclusion The current overview shows that FNB is more effective than PCA and LIA, the patients’ satisfaction is better. Due to the limitations of the quantity and quality of included studies, the above conclusions are needed to be verified by more studies.
Objective To assess the efficacy and safety of nerve-stimulator-guide needle placement in the peripheral nerve blockade. Methods The Cochrane Library, MEDLINE, OVID, VIP, CNKI and CBM were searched. The quality of the included studies was evaluated by three reviewers, and meta-analysis was performed. Results Twenty studies involving 1 287 participants related to needle placement in the peripheral nerve blockade were included. There were only 2 studies that described a detailed randomization method and allocation concealment and blinding, and the others were inadequate. Meta-analysis based on the included studies showed that: ① Absolute success ratio: nerve-stimulator-guide was higher than eliciting paraesthesia (OR= 4.05, 95%CI 2.57 to 6.36, Plt;0.00001) and anatomy localization (OR=30.3, 95%CI 1.73 to 532.74, P=0.02), but lower than ultrasound-guide-localization (OR=0.27, 95%CI 0.10 to 0.74, P=0.01). ② Onset time of the block: nerve-stimulator-guide was similar to eliciting paraesthesia (WMD= –1.70, 95%CI –?4.50 to 0.95, P=0.08), faster than arteriopalmus localization (WMD= 8.38, 95%CI 0.72 to 16.04, Plt;0.000 01), but slower than ultrasound-guide-localization (WMD= 8.38, 95%CI 0.72 to 16.04, P=0.04). ③ Ratio of complication associated to block: nerve-stimulator-guide was similar to eliciting paraesthesia (OR= 1.01, 95%CI 0.55 to 1.86, P=0.97), anatomy localization (WMD= 0.06, 95%CI 0.00 to 1.21, P=0.07) and arteriopalmus localization (WMD= 8.82, 95%CI 0.10 to 4.11, P=0.65), but higher than ultrasound-guide-localization (OR= 5.03, 95%CI 1.74 to 14.49, P=0.003). ④ Time to block: nerve-stimulator-guide was similar to eliciting paraesthesia (WMD=0.02, 95%CI –0.46 to 0.51, P=0.92), shorter than arteriopalmus localization (WMD= –4.00, 95%CI –5.58 to –2.42, Plt;0.000 01) and longer than ultrasound-guide-localization (WMD= 1.90, 95%CI 0.47 to 3.33, P=0.009). ⑤ Patient-accepted ratio: nerve-stimulator-guide was higher than eliciting paraesthesia (OR=2.32, 95%CI 1.02 to 5.30, P=0.05), and similar to arteriopalmus localization (OR=8.14, 95%CI 0.88 to 75.48, P=0.06). Conclusion Nerve-stimulator-guide location is a precise, effective and safe localization method. Due to moderate risk of selection bias and detection bias of included studies, the evidence is not b. Our results suggest that well-designed double-blind randomized controlled and larger-scale trials on the use of nerve stimulator in the peripheral nerve block are needed.

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.
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.
