Meta-Analysis
This study aimed to investigate the efficacy and safety of trigeminal parasympathetic pathway (TPP) stimulation in the treatment of dry eye. A comprehensive search for randomized clinical trials was performed in seven databases (MEDLINE, Embase, CENTRAL, etc.) up to 28 February 2023. After screening the suitable studies, the data were extracted and transformed as necessary. Data synthesis and analysis were performed using Review Manager 5.4, and the risk of bias and quality of evidence were evaluated with the recommended tools. Fourteen studies enrolling 1714 patients with two methods (electrical and chemical) of TPP stimulation were included. Overall findings indicate that TPP stimulation was effective in reducing subjective symptom score (standardized mean difference [SMD], -0.45; 95% confidence interval [CI], -0.63 to -0.28), corneal fluorescence staining (mean difference [MD], -0.78; 95% CI, -1.39 to -0.18), goblet cell area (MD, -32.10; 95% CI, -54.58 to -9.62) and perimeter (MD, -5.90; 95% CI, -10.27 to -1.53), and increasing Schirmer's test score (SMD, 0.98; 95% CI, 0.65 to 1.31) and tear film break-up time (SMD, 0.57; 95% CI, 0.19 to 0.95). Compared to inactive or low-activity stimulation controls, it has a higher incidence of adverse events. Therefore, TPP stimulation may be an effective treatment for dry eye, whether electrical or chemical. Adverse events are relatively mild and tolerable. Due to the high heterogeneity and low level of evidence, the current conclusions require to be further verified.

Meta-Analysis
OBJECTIVE
Thoracic outlet syndrome (TOS) is a complex disorder affecting the neurovascular structures of the upper extremity as they traverse from the neck and thorax to the upper extremity. This systematic review and meta-analysis focuses on pediatric TOS, offering insights into its clinical presentation, etiology, treatment modalities, and outcomes in contrast to those reported in adult TOS.
METHODS
A comprehensive search for pediatric TOS in the PubMed database using PRISMA guidelines identified 6 relevant studies published between 2008 and 2022. In total, 227 pediatric TOS cases in 216 patients were analyzed. Data categories explored for TOS in pediatric patients included study design, number of patients included, mean age and sex of patients, TOS type, laterality, bony abnormalities, time to surgery, symptoms, treatment modalities, initial surgical technique, surgical complications, percent lost to follow-up, mean follow-up period, and treatment outcome.
RESULTS
The results from the 6 studies of 216 patients show a distinct pattern in pediatric TOS, with a 1.84:1 female-to-male ratio, a mean age of 15.49 years, and a lower prevalence of neurogenic TOS (75%, 95% CI 0.41-0.93; I2 = 86%, p < 0.01) compared with the prevailing literature on adults (87.5%-99%). Venous and arterial TOS accounted for a higher proportion of cases in pediatric patients than in adults, challenging the traditional adult-oriented perspective. Right-sided presentations were more common, reflecting right-arm dominance in most individuals. Additionally, bony abnormalities were more common in adults (30%) than in children (10.65%). Treatments involved mixed methods, predominantly using combinations of muscle resection (95.26%), neurolysis (78.02%), and bone resection (72.41%). Patients had high rates of symptom improvement (89%, 95% CI 0.67-0.97; I2 = 85%, p < 0.01) following surgery, with improvement of symptoms ranging from slight to complete relief. Complications were infrequent (5.66%), and most patients reported positive outcomes. The limitations of this analysis include subjective diagnostic and reporting criteria for TOS given its broad range of presentations.
CONCLUSIONS
This systematic review and meta-analysis brings to light the distinctive characteristics of pediatric TOS and underscores the importance of recognizing these differences to ensure accurate diagnosis and effective treatment in this patient population. Further research is needed to understand the predictive value of conservative treatments, especially in pediatric TOS cases.

Review
: For more than two decades, the surgical treatment of post-stroke spastic hands has been displaced by botulinum toxin therapy and is currently underutilized. : This article aimed to assess the potential of surgery for treating a post-stroke spastic upper extremity through a systematic review of the literature on surgical approaches that are adopted in different profiles of patients and on their outcomes and complications. : Medline PubMed, Web of Science, SCOPUS, and Cochrane Library databases were searched for observational and experimental studies published in English up to November 2022. The quality of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluations (GRADE) system. : The search retrieved 501 abstracts, and 22 articles were finally selected. The GRADE-assessed quality of evidence was low or very low. The results of the reviewed studies suggest that surgery is a useful, safe, and enduring treatment for post-stroke spastic upper extremities, although most studied patients were candidates for hygienic improvements alone. Patients usually require an individualized combination of techniques. Over the past ten years, interest has grown in procedures that act on the peripheral nerve. : Despite the lack of comparative studies on the effectiveness, safety, and cost of the treatments, botulinum toxin has displaced surgery for these patients. Studies to date have found surgery to be an effective and safe approach, but their weak design yields only poor-quality evidence, and clinical trials are warranted to compare these treatment options.

Journal of Clinical Anesthesia Jun 2024To identify whether adding ketamine to the local anesthetics (LA) in the regional anesthesia could prolong the duration of analgesia. (Meta-Analysis)
Meta-Analysis
STUDY OBJECTIVE
To identify whether adding ketamine to the local anesthetics (LA) in the regional anesthesia could prolong the duration of analgesia.
DESIGN
A Systematic review and meta-analysis of randomized controlled trials.
SETTING
The major dates were obtained in the operating room and the postoperative recovery ward.
PATIENTS
A total of 1011 patients at ASA physical status I and II were included in the analysis. Procedure performed including cesarean section, orthopedic, radical mastectomy, urological or lower abdominal surgery and intracavitary brachytherapy implants insertion.
INTERVENTIONS
After an extensive search of the electronic database, patients received regional anesthesia combined or not combined general anesthesia and with or without adding ketamine to LA were included in the analysis. The regional anesthesia includes spinal anesthesia, brachial plexus block, pectoral nerve block, transversus abdominis plane block and femoral and sciatic nerve block.
MEASUREMENT
The primary outcome was the duration of analgesia. Secondary outcomes were the duration and onset time of motor and sensory block as well as the ketamine-related adverse effect. Data are expressed in mean differences in continuous data and odds ratios (OR) for dichotomous data with 95% confidence intervals. The risk of bias of the included studies was evaluated using the revised Cochrane risk of bias tool for randomized trials. The quality of evidence for each outcome was rated according to the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) Working Group system.
MAIN RESULT
Twenty randomized controlled trials were included in the analysis. When ketamine was used as an adjuvant to LA, the duration of analgesia could be prolonged(172.21 min, 95% CI, 118.20 to 226.22; P<0.00001, I = 98%), especially in the peripheral nerve block(366.96 min, 95% CI, 154.19 to 579.74; P = 0.0007, I = 98%). Secondary outcomes showed ketamine could prolong the duration of sensory block(29.12 min, 95% CI, 10.22 to 48.01; P = 0.003, I = 96%) but no effect on the motor block(6.94 min, 95% CI,-2.65 to 16.53;P = 0.16, I = 84%), the onset time of motor and sensory block (motor onset time, -1.17 min, 95% CI, -2.67 to 0.34; P = 0.13, I = 100%; sensory onset time, -0.33 min, 95% CI,-0.87 to 0.20; P = 0.23, I = 96%) as well as the ketamine-related adverse effect(OR, 1.97, 95% CI,0.93 to 4.17;P = 0.08, I = 57%).
CONCLUSION
This study indicates that ketamine could be an ideal adjuvant to local anesthetics regardless of the types of anesthesia. Overall, the quality of the evidence is low.

Review
This article aims to provide a concise overview of the best available evidence for managing post-stroke spasticity. A modified scoping review, conducted following the PRISMA guidelines and the PRISMA Extension for Scoping Reviews (PRISMA-ScR), involved an intensive search on Medline and PubMed from 1 January 2000 to 31 August 2023. The focus was placed on high-quality (GRADE A) medical, rehabilitation, and surgical interventions. In total, 32 treatments for post-stroke spasticity were identified. Two independent reviewers rigorously assessed studies, extracting data, and evaluating bias using GRADE criteria. Only interventions with GRADE A evidence were considered. The data included the study type, number of trials, participant characteristics, interventions, parameters, controls, outcomes, and limitations. The results revealed eleven treatments supported by GRADE A evidence, comprising 14 studies. Thirteen were systematic reviews and meta-analyses, and one was randomized control trial. The GRADE A treatments included stretching exercises, static stretching with positional orthosis, transcutaneous electrical nerve stimulation, extracorporeal shock wave therapy, peripheral magnetic stimulation, non-invasive brain stimulation, botulinum toxin A injection, dry needling, intrathecal baclofen, whole body vibration, and localized muscle vibration. In conclusion, this modified scoping review highlights the multimodal treatments supported by GRADE A evidence as being effective for improving functional recovery and quality of life in post-stroke spasticity. Further research and exploration of new therapeutic options are encouraged.

Meta-Analysis
STUDY OBJECTIVE
We conducted a systematic review and network meta-analysis to evaluate the comparative efficacy of peripheral nerve block types for preoperative pain management of hip fractures.
METHODS
We searched Cochrane, Central Register of Controlled Trials, MEDLINE, EMBASE, ICTRP, ClinicalTrials.gov, and Google Scholar for randomized clinical trials. We included participants aged more than 16 years with hip fractures who received peripheral nerve blocks or analgesics for preoperative pain management. The primary outcomes were defined as absolute pain score 2 hours after block placement, preoperative consumption of morphine equivalents, and length of hospital stay. We used a random-effects network meta-analysis conceptualized in the Bayesian framework. Confidence of evidence was assessed using Confidence in Network Meta-Analysis (CINeMA).
RESULTS
We included 63 randomized controlled studies (4,778 participants), of which only a few had a low risk of bias. The femoral nerve block, 3-in-1 block, fascia iliaca compartment block, and pericapsular nerve group block yielded significantly lowered pain scores at 2 hours after block placement compared with those with no block (standardized mean differences [SMD]: -1.1; 95% credible interval [CrI]: -1.7 to -0.48, [confidence of evidence: low]; SMD: -1.8; 95% CrI: -3.0 to -0.55, [low]; SMD: -1.4; 95% CrI: -2.0 to -0.72, [low]; SMD: -2.3; 95% CrI: -3.2 to -1.4, [moderate], respectively). The pericapsular nerve group block, 3-in-1 block, fascia iliaca compartment block, and femoral nerve block resulted in lower pain scores than the no-block group. Additionally, the pericapsular nerve group block yielded a lower pain score than femoral nerve block or fascia iliaca compartment block (SMD: -1.21; 95% CrI: -2.18 to -0.23, [very low]: SMD: -0.92; 95% CrI: -1.70 to -0.16, [low]). However, both the fascia iliaca compartment block and femoral nerve block did not show a reduction in morphine consumption compared with no block. To our knowledge, no studies have compared the pericapsular nerve group block with other methods regarding morphine consumption. Furthermore, no significant difference was observed between peripheral nerve blocks and no block in terms of the length of hospital stay.
CONCLUSIONS
Compared with no block, preoperative peripheral nerve blocks for hip fractures appear to reduce pain 2 hours after block placement. Comparing different blocks, pericapsular nerve group block might be superior to fascia iliaca compartment block and femoral nerve block for pain relief, though the confidence evidence was low in most comparisons because of the moderate to high risk of bias in many of the included studies and the high heterogeneity of treatment strategies across studies. Therefore, further high-quality research is needed.

Analgesic efficacy of local infiltration anaesthesia versus femoral nerve block in alleviating postoperative wound pain following total knee arthroplasty: A systematic review and meta-analysis.
Total knee arthroplasty (TKA) often involves significant postoperative pain, necessitating effective analgesia. This meta-analysis compares the analgesic efficacy of local infiltration anaesthesia (LIA) and femoral nerve block (FNB) in managing postoperative wound pain following TKA. Adhering to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, this meta-analysis was structured around the PICO framework, assessing studies that directly compared LIA and FNB in TKA patients. A comprehensive search across PubMed, Embase, Web of Science and the Cochrane Library was conducted without time restrictions. Studies were included based on specific criteria such as participant demographics, study design and outcomes like pain scores and opioid consumption. Quality assessment utilized the Cochrane Collaboration's risk of bias tool. The statistical approach was determined based on heterogeneity, with the choice of fixed- or random-effects models guided by the I statistic. Sensitivity analysis and evaluation of publication bias using funnel plots and Egger's linear regression test were also conducted. From an initial pool of 1275 articles, eight studies met the inclusion criteria. These studies conducted in various countries from 2007 to 2016. The meta-analysis showed no significant difference in resting and movement-related Visual Analogue Scale scores post-TKA between the LIA and FNB groups. However, LIA was associated with significantly lower opioid consumption. The quality assessment revealed a low risk of bias in most studies, and the sensitivity analysis confirmed the stability of these findings. There was no significant publication bias detected. Both LIA and FNB are effective in controlling postoperative pain in TKA patients, but LIA offers the advantage of lower opioid consumption. Its simplicity, cost-effectiveness and opioid-sparing nature make LIA the recommended choice for postoperative analgesia in knee replacement surgeries.

Meta-Analysis Review
BACKGROUND
Acute and chronic postoperative pain are important healthcare problems, which can be treated with a combination of opioids and regional anaesthesia. The erector spinae plane block (ESPB) is a new regional anaesthesia technique, which might be able to reduce opioid consumption and related side effects.
OBJECTIVES
To compare the analgesic effects and side effect profile of ESPB against no block, placebo block or other regional anaesthetic techniques.
SEARCH METHODS
We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase and Web of Science on 4 January 2021 and updated the search on 3 January 2022.
SELECTION CRITERIA
Randomised controlled trials (RCTs) investigating adults undergoing surgery with general anaesthesia were included. We included ESPB in comparison with no block, placebo blocks or other regional anaesthesia techniques irrespective of language, publication year, publication status or technique of regional anaesthesia used (ultrasound, landmarks or peripheral nerve stimulator). Quasi-RCTs, cluster-RCTs, cross-over trials and studies investigating co-interventions in either arm were excluded.
DATA COLLECTION AND ANALYSIS
Two review authors independently assessed all trials for inclusion and exclusion criteria, and risk of bias (RoB), and extracted data. We assessed risk of bias using the Cochrane RoB 2 tool, and we used GRADE to rate the certainty of evidence for the primary outcomes. The primary outcomes were postoperative pain at rest at 24 hours and block-related adverse events. Secondary outcomes were postoperative pain at rest (2, 48 hours) and during activity (2, 24 and 48 hours after surgery), chronic pain after three and six months, as well as cumulative oral morphine requirements at 2, 24 and 48 hours after surgery and rates of opioid-related side effects.
MAIN RESULTS
We identified 69 RCTs in the first search and included these in the systematic review. We included 64 RCTs (3973 participants) in the meta-analysis. The outcome postoperative pain was reported in 38 out of 64 studies; block-related adverse events were reported in 40 out of 64 studies. We assessed RoB as low in 44 (56%), some concerns in 24 (31%) and high in 10 (13%) of the study results. Overall, 57 studies reported one or both primary outcomes. Only one study reported results on chronic pain after surgery. In the updated literature search on 3 January 2022 we found 37 new studies and categorised these as awaiting classification. ESPB compared to no block There is probably a slight but not clinically relevant reduction in pain intensity at rest 24 hours after surgery in patients treated with ESPB compared to no block (visual analogue scale (VAS), 0 to 10 points) (mean difference (MD) -0.77 points, 95% confidence interval (CI) -1.08 to -0.46; 17 trials, 958 participants; moderate-certainty evidence). There may be no difference in block-related adverse events between the groups treated with ESPB and those receiving no block (no events in 18 trials reported, 1045 participants, low-certainty evidence). ESPB compared to placebo block ESPB probably has no effect on postoperative pain intensity at rest 24 hours after surgery compared to placebo block (MD -0.14 points, 95% CI -0.29 to 0.00; 8 trials, 499 participants; moderate-certainty evidence). There may be no difference in block-related adverse events between ESPB and placebo blocks (no events in 10 trials reported; 592 participants; low-certainty evidence). ESPB compared to other regional anaesthetic techniques Paravertebral block (PVB) ESPB may not have any additional effect on postoperative pain intensity at rest 24 hours after surgery compared to PVB (MD 0.23 points, 95% CI -0.06 to 0.52; 7 trials, 478 participants; low-certainty evidence). There is probably no difference in block-related adverse events (risk ratio (RR) 0.27, 95% CI 0.08 to 0.95; 7 trials, 522 participants; moderate-certainty evidence). Transversus abdominis plane block (TAPB) ESPB may not have any additional effect on postoperative pain intensity at rest 24 hours after surgery compared to TAPB (MD -0.16 points, 95% CI -0.46 to 0.14; 3 trials, 160 participants; low-certainty evidence). There may be no difference in block-related adverse events (RR 1.00, 95% CI 0.21 to 4.83; 4 trials, 202 participants; low-certainty evidence). Serratus anterior plane block (SAPB) The effect on postoperative pain could not be assessed because no studies reported this outcome. There may be no difference in block-related adverse events (RR 1.00, 95% CI 0.06 to 15.59; 2 trials, 110 participants; low-certainty evidence). Pectoralis plane block (PECSB) ESPB may not have any additional effect on postoperative pain intensity at rest 24 hours after surgery compared to PECSB (MD 0.24 points, 95% CI -0.11 to 0.58; 2 trials, 98 participants; low-certainty evidence). The effect on block-related adverse events could not be assessed. Quadratus lumborum block (QLB) Only one study reported on each of the primary outcomes. Intercostal nerve block (ICNB) ESPB may not have any additional effect on postoperative pain intensity at rest 24 hours after surgery compared to ICNB, but this is uncertain (MD -0.33 points, 95% CI -3.02 to 2.35; 2 trials, 131 participants; very low-certainty evidence). There may be no difference in block-related adverse events, but this is uncertain (RR 0.09, 95% CI 0.04 to 2.28; 3 trials, 181 participants; very low-certainty evidence). Epidural analgesia (EA) We are uncertain whether ESPB has an effect on postoperative pain intensity at rest 24 hours after surgery compared to EA (MD 1.20 points, 95% CI -2.52 to 4.93; 2 trials, 81 participants; very low-certainty evidence). A risk ratio for block-related adverse events was not estimable because only one study reported this outcome.
AUTHORS' CONCLUSIONS
ESPB in addition to standard care probably does not improve postoperative pain intensity 24 hours after surgery compared to no block. The number of block-related adverse events following ESPB was low. Further research is required to study the possibility of extending the duration of analgesia. We identified 37 new studies in the updated search and there are three ongoing studies, suggesting possible changes to the effect estimates and the certainty of the evidence in the future.

Review
Peripheral nerves are subjected to mechanical tension during limb movements and body postures. Nerve response to tensile stress can be assessed in vivo with shear-wave elastography (SWE). Greater tensile loads can lead to greater stiffness, which can be quantified using SWE. Therefore, this study aimed to conduct a systematic review and meta-analysis to perform an overview of the effect of joint movements on nerve mechanical properties in healthy nerves. The initial search (July 2023) yielded 501 records from six databases (PubMed, Embase, Scopus, Web of Science, Cochrane, and Science Direct). A total of 16 studies were included and assessed with a modified version of the Downs and Black checklist. Our results suggest an overall tendency for stiffness increase according to a pattern of neural tensioning. The main findings from the meta-analysis showed a significant increase in nerve stiffness for the median nerve with wrist extension (SMD [95%CI]: 3.16 [1.20, 5.12]), the ulnar nerve with elbow flexion (SMD [95%CI]: 2.91 [1.88, 3.95]), the sciatic nerve with ankle dorsiflexion (SMD [95%CI]: 1.13 [0.79, 1.47]), and the tibial nerve with both hip flexion (SMD [95%CI]: 2.14 [1.76, 2.51]) and ankle dorsiflexion (SMD [95%CI]: 1.52 [1.02, 2.02]). The effect of joint movement on nerve stiffness also depends on the nerve segment, the amount of movement of the joint mobilized, and the position of other joints comprised in the entirety of the nerve length. However, due to the limited number of studies, many aspects of nerve behavior together with the effect of using different ultrasound equipment or transducers for nerve stiffness evaluation still need to be fully investigated.

Comparative effectiveness of pericapsular nerve group block versus fascia iliac compartment block on postoperative wound pain management in patients undergoing hip fracture surgery: A systematic review and meta-analysis.
Hip fracture surgeries are challenging, with postoperative pain management being a critical component of patient care. This systematic review and meta-analysis aimed to compare the effectiveness of Pericapsular nerve group block (PENGB) and fascia iliac compartment block (FICB) in postoperative wound pain management for patients undergoing hip fracture surgery. The study followed the PRISMA guidelines and was structured around the PICO framework. Comprehensive searches were conducted across PubMed, Embase, Web of Science, and the Cochrane Library. Inclusion criteria were limited to RCTs comparing the effectiveness of PENGB and FICB in adult patients undergoing hip fracture surgery. Key outcomes included pain control effectiveness, safety, and complication incidence. The quality of studies was assessed using the Cochrane Collaboration's risk of bias tool. Statistical heterogeneity was evaluated using I statistics, and meta-analysis effect values were calculated using random-effects or fixed-effect models, depending on the degree of heterogeneity. The search identified 1095 articles, with 5 studies meeting inclusion criteria. The meta-analysis revealed that PENGB and FICB were comparable in managing postoperative pain and opioid consumption. However, PENGB significantly reduced the incidence of quadriceps muscle weakness (RR = 0.12, p < 0.05) and did not increase the risk of PONV (RR = 1.36, p = 0.51), suggesting its advantage in maintaining motor function without adding to PONV complications. No significant publication bias was detected. PENGB is comparable to FICB in pain and opioid consumption management after hip fracture surgeries. Its significant benefit lies in reducing the incidence of quadriceps muscle weakness, facilitating better postoperative mobility. Additionally, PENGB does not increase the risk of postoperative nausea and vomiting, underlining its suitability for comprehensive postoperative care in hip fracture patients.
