In the wake of developments in minimally invasive technology, the method has brought a number of new breakthroughs. We reviewed the effect of the success of splanchnicectomy.
ObjectiveTo study the analgesia and rehabilitation effect of femoral nerve block after anterior cruciate ligament reconstruction (ACLR). MethodsDuring June to September 2014, 62 patients who were scheduled to undergo ACLR were randomly divided into two groups:femoral nerve block group (n=31) and control group (n=31). All the patients were given celecoxib 200 mg (twice per day) three days before surgery. Patients in the femoral nerve block group were given a single-injection femoral nerve block (SFNB) half an hour before surgery (ropivacaine 0.75%, 30 mL), Both of the two groups underwent ice therapy after surgery. The visual analogue scale (VAS) scores, knee joint range of motion, the muscle strength of quadriceps femoris, the side effects, complications and infection rate were recorded after the operation. ResultsThe VAS scores were significantly lower in the femoral nerve block group within 2 hours to 7 days after surgery (P<0.05), and the use of morphine was less than the control group in all the time points with statistical significance (P<0.05). The muscle strength of quadriceps femoris was significantly weaker in the femoral nerve block group than the control group in the first 12 hours (P<0.05). The side effects and infection rate between the two group had no significant difference (P>0.05). ConclusionThe femoral nerve block in anterior cruciate ligament reconstruction before surgery has a good effect on postoperative analgesia and rehabilitation, which is worth popularizing and applying.
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.
Objective To compare the effect of sciatic nerve block (SNB) combined with continuted femoral nerve block (FNB) or continuted adductor canal block (ACB) on pain and motor function after total knee arthroplasty (TKA). Methods A total of 60 patients with TKA-treated osteoarthritis of the knee who met the selection criteria were enrolled between November 2020 and February 2021 and randomised allocated into the study group (SNB combined with continuted ACB) and the control group (SNB combined with continuted FNB), with 30 cases in each group. There was no significant difference in gender, age, body mass, height, body mass index, preoperative Hospital for Special Surgery (HSS) score, femoral tibial angle, and medial proximal tibial angle between the two groups (P>0.05). The operation time, the initial time to the ground, the initial walking distance, and the postoperative hospital stay were recorded. At 2, 4, 6, 12, 24, and 48 hours after operation, the numerical rating scale (NRS) score was used to evaluate the rest pain around the knee joint, the quadriceps femoris muscle strength was evaluated by the freehand muscle strength method, and the knee flexion and extension angles were measured. Results There was no significant difference in the operation time and initial walking distance between the two groups (P>0.05); the initial time to the ground and postoperative hospital stay of the study group were significantly shorter than those of the control group (P<0.05). Except for the 48-hour postoperative NRS score of the study group, which was significantly lower than that of the control group (P<0.05), there was no significant difference in the NRS scores between the two groups at the remaining time points (P>0.05). The quadriceps femoris muscle strength from 4 to 24 hours postoperatively and the knee extension angle from 2 to 6 hours postoperatively of the study group were significantly better than those of the control group (P<0.05); the differences in the quadriceps femoris muscle strength and knee extension and flexion angles between the two groups at the remaining time points were not significant (P>0.05). Conclusion SNB combined with either continuted ACB or continuted FNB can effectively relieve pain in patients after TKA, and compared with combined continuted FNB, combined continuted ACB has less effect on quadriceps femoris muscle strength, and patients have better recovery of knee flexion and extension mobility.
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 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.
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.

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.
