Meta-Analysis
OBJECTIVES
To evaluate the clinical value and safety of combined anesthesia of acupuncture-pharmacotherapy in pulmonary resection surgery.
METHODS
The randomized controlled trials (RCTs) related to combined anesthesia of acupuncture-pharmacotherapy in pulmonary resection surgery were searched in PubMed, EMbase, Cochrane Library, Web of Science, SinoMed, CNKI, VIP database, Wanfang database, ClinicalTrials.gov, and the Chinese Clinical Trial Registry (http://www.chictr.org.cn/) from the inception of each database up to July 12, 2022. The methodological quality of the included studies was assessed using the Cochrane risk of bias tool, and Meta-analysis was conducted using RevMan5.4.
RESULTS
A total of 33 RCTs were included, involving 2 526 participants. The Meta-analysis results showed that compared to conventional anesthesia, the patients receiving combined anesthesia of acupuncture-pharmacotherapy had more stable vital signs during surgery, reduced intraoperative fentanyl usage [=-3.73, 95%(-5.28, -2.18), =4.72, <0.000 01], decreased postoperative sufentanil consumption [=-20.85, 95%(-24.84, -16.86), =10.24, <0.000 01], reduced total/effective presses of the postoperative patient-controlled analgesia pump [=-5.70, 95% (-9.04, -2.36), =3.35, =0.000 8], lowered postoperative pain visual analogue scale (VAS) [=-1.63, 95%(-2.02, -1.23), =7.97, <0.000 01], shorter length of postoperative hospital stay [=-1.14, 95%(-1.85, -0.43), =3.15, =0.002], and higher levels of CD 4+ T lymphocytes, CD 8+ T lymphocytes, natural killer (NK) cell activity, and superoxide dismutase (SOD). Additionally, tumor necrosis factor-alpha (TNF-α), adrenaline and cortisol levels were decreased (<0.05). No adverse events related to acupuncture or electrical stimulation were reported, and the incidence of postoperative complications was lower than that of conventional anesthesia [=0.47, 95%(0.36, 0.62), =5.36, <0.000 01].
CONCLUSIONS
The combined anesthesia of acupuncture-pharmacotherapy in pulmonary resection surgery could improve anesthesia and analgesia effectiveness, reduce anesthesia drug usage, regulate immune responses, suppress stress reactions, and the safety is satisfactory. However, there is substantial heterogeneity among the included studies, and outcome measures vary widely. Further large-sample, high-quality, internationally standardized clinical trials are needed to clarify its clinical value and safety, providing reliable evidence for clinical practice.

Meta-Analysis Review
Pharmacological agents for procedural sedation and analgesia in the emergency department and intensive care unit: a systematic review and network meta-analysis of randomised trials.
BACKGROUND
We aimed to evaluate the comparative effectiveness and safety of various i.v. pharmacologic agents used for procedural sedation and analgesia (PSA) in the emergency department (ED) and ICU. We performed a systematic review and network meta-analysis to enable direct and indirect comparisons between available medications.
METHODS
We searched Medline, EMBASE, Cochrane, and PubMed from inception to 2 March 2023 for RCTs comparing two or more procedural sedation and analgesia medications in all patients (adults and children >30 days of age) requiring emergent procedures in the ED or ICU. We focused on the outcomes of sedation recovery time, patient satisfaction, and adverse events (AEs). We performed frequentist random-effects model network meta-analysis and used the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach to rate certainty in estimates.
RESULTS
We included 82 RCTs (8105 patients, 78 conducted in the ED and four in the ICU) of which 52 studies included adults, 23 included children, and seven included both. Compared with midazolam-opioids, recovery time was shorter with propofol (mean difference 16.3 min, 95% confidence interval [CI] 8.4-24.3 fewer minutes; high certainty), and patient satisfaction was better with ketamine-propofol (mean difference 1.5 points, 95% CI 0.3-2.6 points, high certainty). Regarding AEs, compared with midazolam-opioids, respiratory AEs were less frequent with ketamine (relative risk [RR] 0.55, 95% CI 0.32-0.96; high certainty), gastrointestinal AEs were more common with ketamine-midazolam (RR 3.08, 95% CI 1.15-8.27; high certainty), and neurological AEs were more common with ketamine-propofol (RR 3.68, 95% CI 1.08-12.53; high certainty).
CONCLUSION
When considering procedural sedation and analgesia in the ED and ICU, compared with midazolam-opioids, sedation recovery time is shorter with propofol, patient satisfaction is better with ketamine-propofol, and respiratory adverse events are less common with ketamine.

Meta-Analysis Review
Influence of different volumes and frequency of programmed intermittent epidural bolus in labor on maternal and neonatal outcomes: A systematic review and network meta-analysis.
STUDY OBJECTIVE
In labor, programmed intermittent epidural bolus (PIEB) can be defined as the bolus administration of epidural solution at scheduled time intervals. Compared to continuous epidural infusion (CEI) with or without patient controlled epidural analgesia (PCEA), PIEB has been associated with decreased pain scores and need for rescue analgesia and increased maternal satisfaction. The optimal volume and dosing interval of PIEB, however, has still not been determined.
DESIGN
Systematic review and network meta-analysis registered with PROSPERO (CRD42022362708).
SETTINGS
Labor.
PATIENTS
Pregnant patients.
INTERVENTIONS
Central, CINAHL, Global Health, Ovid Embase, Ovid Medline and Web of Science were searched for randomized controlled trials that examined pregnant patients in labor who received CEI or PIEB with or without a PCEA component. Network meta-analysis was performed with a frequentist method, facilitating the indirect comparison of PIEB with different volumes and dosing intervals through the common comparator of CEI and substituting or supplementing direct comparisons with these indirect ones. Continuous and dichotomous outcomes were presented as mean differences and odds ratios, respectively, with 95% confidence intervals. The risk of bias was evaluated using the Cochrane risk of bias 2 tool.
MAIN RESULTS
Overall, 30 trials were included. For the first primary endpoint, need for rescue analgesia, PIEB delivered at a volume of 4 ml and frequency of 45 min (4/45) was inferior to PIEB 8/45 (OR 3.55; 95% CI 1.12-11.33), PIEB 10/60 was superior to PIEB 2.5/15 (OR 0.36; 95% CI 0.16-0.82), PIEB 4/45 (OR 0.14; 95% CI 0.03-0.71) and PIEB 5/60 (OR 0.23; 95% CI 0.08-0.70), and PIEB 5/30 was not inferior to PIEB 10/60 (OR 0.61; 95% CI 0.31-1.19). For the second primary endpoint, maternal satisfaction, no differences were present between the various PIEB regimens. The quality of evidence for these multiple primary endpoints was low owing to the presence of serious limitations and imprecision. Importantly, PIEB 5/30 decreased the pain score at 4 h compared to PIEB 2.5/15 (MD 2.45; 95% CI 0.13-4.76), PIEB 5/60 (MD -2.28; 95% CI -4.18--0.38) and PIEB 10/60 (MD 1.73; 95% CI 0.31-3.16). Mean ranking of interventions demonstrated PIEB 10/60 followed by PIEB 5/30 to be best placed to reduce the cumulative dose of local anesthetic, and this resulted in an improved incidence of lower limb motor blockade for PIEB 10/60 in comparison to CEI (OR 0.30; 95% CI 0.14-0.67). No differences in neonatal outcomes were found. Some concerns were present for the risk of bias in two thirds of trials and the risk of bias was shown to be high in the remaining one third of trials.
CONCLUSIONS
Future research should focus on PIEB 5/30 and PIEB 10/60 and how the method of analgesia initiation, nature and concentration of local anesthetic, design of epidural catheter and rate of administration might influence outcomes related to the mother and neonate.

Review
Opioid-related fatalities are a leading cause of accidental death in the United States. Appendicitis is a common cause of abdominal pain in children and adolescents. The management of pain throughout the laparoscopic appendectomy (LA) in the pediatric population is a critical concern. This study aimed to evaluate trends in analgesic use and patient satisfaction following LA, with a focus on reducing the reliance on opioids for pain management. From 2003 to 2023, 18258 articles were filtered for all types of analgesic use with LA. The publications were screened using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, and 19 studies were included for analysis and review. The study included peer-reviewed experimental and observational studies involving individuals under 18 years. Pain management strategies varied across studies, involving a combination of analgesics, nerve blocks, and wound infiltrations. Analgesics such as acetaminophen, non-steroidal anti-inflammatory drugs (NSAIDs), and opioids were administered before and after surgery. Some studies implemented patient-controlled analgesia (PCA) pumps. Other studies explored non-pharmacological interventions like magnetic acupuncture. The results showed a reduction in the need for postoperative analgesics in patients treated with LA, particularly when using non-opioid medications and novel analgesic techniques. Pediatric patients who received gabapentin reported lower opioid use, shorter hospital stays, and high satisfaction rates. However, the reliance on opioids remained significant in some cases, particularly among patients with peritonitis who required more morphine. Pain management in pediatric patients is multifaceted, involving preoperative and postoperative analgesics, nerve blocks, and PCA pumps. Efforts to improve pain management following pediatric LA while reducing opioid reliance are essential in the context of the ongoing opioid epidemic. The findings from this study highlight the potential benefits of non-opioid analgesics, nerve blocks, and alternative methods for managing postoperative pain in <18 appendectomy patients. Further research and standardization of pain management protocols are needed to ensure optimal patient outcomes and minimize the risk of opioid-related complications.

Meta-Analysis
PURPOSE
Enhanced recovery after surgery (ERAS) was characterized as patient-centered, evidence-based, multidisciplinary team-developed routes for a surgical speciality and institution to improve postoperative recovery and attenuate the surgical stress response. However, evidence of their effectiveness in osteoarthroplasty remains sparse. This study aimed to develop an ERAS standard and evaluate the significance of ERAS interventions for postoperative outcomes after primary total hip arthroplasty (THA) or total knee arthroplasty (TKA).
METHODS
We searched Medline, Embase, Cochrane databases, and Clinicaltrials.gov for randomized controlled trials, cohort studies, and case-control studies until 24 February 2023. All relevant data were collected from studies meeting the inclusion criteria. Two reviewers independently assessed the risk of bias and extracted data. The primary outcome was the length of stay (LOS), postoperative complications, and readmission rate. The secondary outcomes included transfusion rate, mortality rate, visual analog score (VAS), the Western Ontario and McMaster University Osteoarthritis Index (WOMAC), Short Form 36 (SF-36) bodily pain (SF-36 BP), SF-36 physical function (SF-36 PF), oxford knee score, and range of motion (ROM).
RESULTS
A total of 47 studies involving 76 971 patients (ERAS group: 29 702, control group: 47 269) met the inclusion criteria and were included in the meta-analysis. The result showed that ERAS could significantly shorten the LOS (WMD = -2.65, P < .001), reduce transfusion rate (OR = 0.40, P < .001), and lower 30-day postoperative mortality (OR = 0.46, P = .01) without increasing postoperative complications or readmission rate. Apart from that, ERAS may decrease patients' VAS (WMD = -0.88, P = .01) while improving their ROM (WMD = 6.65, P = .004), SF-36 BP (WMD = 4.49, P < .001), and SF-36 PF (WMD = 3.64, P < .001) scores. However, there was no significant difference in WOMAC, oxford knee score between the ERAS and control groups.Furthermore, we determined that the following seven components of the ERAS program are highly advised: avoid bowel preparation, PONV prophylaxis, standardized anesthesia, use of local anesthetics for infiltration analgesia and nerve blocks, tranexamic acid, prevent hypothermia, and early mobilization.
CONCLUSION
Our meta-analysis suggested that the ERAS could significantly shorten the LOS, reduce transfusion rate, and lower 30-day postoperative mortality without increasing postoperative complications or readmission rate after THA and TKA. Meanwhile, ERAS could decrease the VAS of patients while improving their ROM, SF-36 BP, and SF-36 PF scores. Finally, we expect future studies to utilize the seven ERAS elements proposed in our meta-analysis to prevent increased readmission rate for patients with THA or TKA.

Meta-Analysis
INTRODUCTION
The global low survival rate among ovarian cancer patients has resulted in significant social and economic burdens. Nevertheless, previous studies have produced mixed results when exploring the link between anesthetic techniques and the prognosis of ovarian cancer. The study aims to compare the effect of epidural anesthesia with general anesthesia on survival time after cytoreductive surgery in patients with ovarian cancer.
METHODS
The PubMed (National Library of Medicine), Cochrane library, Web of science, Embase, CNKI (China National Knowledge Internet), Wanfang Med Online (China database), were systematically searched from inception to May, 2023, using the Medical Subject Headings [MeSH] of "Ovarian Neoplasm" and "Anesthesia, Epidural" and free words to identify systematic reviews or meta-analyses. The research methodology involved analyzing randomized controlled trials (RCTs), as well as prospective or retrospective cohort studies, which compared the long-term prognosis of patients with ovarian cancer under general anesthesia combined with epidural anesthesia (GEA) versus general anesthesia alone (GA). The Newcastle Ottawa Scale (NOS) was used to assess methodological quality and bias. Data extraction and assessment of study quality were conducted by two independent reviewers. A meta-analysis was then performed to calculate hazard ratios (HRs) and corresponding 95% confidence intervals (CIs). Overall survival (OS) was defined as the primary outcome, time to tumor recurrence (TTR) was the secondary outcome. Epidural anesthesia could be used intraoperatively and immediately postoperatively (EIP), or postoperatively only (EP). GEA includes EIP and EP.
RESULTS
In total, 8 retrospective cohort studies with 2036 participants met the inclusion criteria. The pooled results demonstrated that GEA could extend OS (HR 0.75, 95% CI 0.67-0.84, I = 0%, P < 0.05, fixed-effect model) when compared with GA in ovarian cancer patients undergoing cytoreductive surgery, but not TTR (sensitivity analysis revealed substantial heterogeneity among the included studies). The result of analyzing a total of 1490 patients in 4 studies was that EIP had a better prognosis on OS than GA (HR 0.68, 95%CI 0.55-0.85, I = 61%, P < 0.05, random-effect model). However, EP had no advantage in TTR (sensitivity analysis revealed it was unstable outcome). Ovarian cancer FIGO(International Federation of Gynecology and Obstetrics) stage III, stage IV compared to stage I on OS was statistically significant, HRs respectively are 3.67 (95%CI 2.25-5.98), I = 0%, fixed-effect model, P < 0.05, and 7.43 (95%CI 3.67-15.03), I = 31%, fixed-effect model, P < 0.05, but there was no statistically significant difference between stage II and stage I, HR 2.00, 95%CI0.98-4.09, I = 0%, fixed-effect model, P > 0.05. 1-10 mm tumor residuals shorten TTR compared with 0 residuals, HR 1.75, 95% CI1.50-2.04, I = 0%, fixed-effect model, P < 0.05.
CONCLUSIONS
It is hard to conclude that postoperative epidural analgesia offers greater benefits than GA. However, general anesthesia combined with epidural anesthesia (EIP) can improve overall survival in ovarian cancer patients, allowing the anesthesiologist to use anesthesia techniques to provide a favorable prognosis for the ovarian cancer patient. Tumor staging and the extent of cell reduction are also critical factors that significantly influence the long-prognosis of ovarian cancer patients.

Review
Dacryocystorhinostomy (DCR) is an effective surgical procedure for addressing lacrimal drainage problems. However, it can be a painful operation that involves incisions both inside and outside the eye, often leading to a high incidence of postoperative nausea and vomiting. Preemptive analgesics can be employed to alleviate this unrelieved pain. Nonetheless, many of the drugs used can induce a wide range of adverse effects. Therefore, the aim of this systematic review and meta-analysis is to assess the current evidence regarding the efficacy of pregabalin in managing postoperative pain following DCR surgery. We conducted a thorough search of five electronic databases, namely, PubMed, Web of Science, Scopus, Cochrane, and Google Scholar, to identify relevant randomized controlled trials (RCTs) published before September 2023. The quality of the included studies was assessed using the Cochrane Risk of Bias tool for RCTs. The outcomes we evaluated included postoperative pain, surgery duration, time to first analgesia, total pethidine consumption, and postoperative nausea and vomiting (PONV). Continues data reported as mean difference (MD), and dichotomous data reported as risk ratio (RR), with 95% confidence interval (CI). A pooled meta-analysis of three RCTs, including 240 patients in both the pregabalin and placebo groups, was conducted. The results revealed that the pooled MD in pain scores was significantly lower in patients treated with pregabalin compared to those receiving a placebo ((MD = -1.35 (95% CI: -1.83 to -0.87, p < 0.00001)). Additionally, the pooled MD of pethidine consumption was significantly lower in patients treated with pregabalin compared to those receiving a placebo (MD = -54.13 (95% CI: -103.77 to -4.50, p = 0.03)). However, there was no statistical significance between both groups in terms of time to first analgesia and duration of surgery (p > 0.05). On the other hand, the pooled RR of PONV was significantly lower in patients treated with pregabalin compared to those receiving a placebo (RR = 0.37 (95% CI: 0.24-0.57, p < 0.001)). This meta-analysis demonstrates that pregabalin is an effective and well-tolerated intervention for reducing postoperative pain and PONV following DCR surgery, without significantly affecting surgery duration or time to first analgesia. These findings support the use of pregabalin in improving patient comfort and outcomes in this surgical context.

Review
OBJECTIVE
Lumbar spine disorders have become an increasingly common health problem in recent years. Modern clinical studies have shown that perioperative analgesia at certain doses can reduce postoperative pain by inhibiting the process of peripheral sensitization and central sensitization, which is also known as "preemptive analgesia," Non-steroidal anti-inflammatory drugs (NSAIDs) are a class of drugs that achieve antipyretic and analgesic effects by inhibiting cyclooxygenase (COX) and affecting the production of prostaglandins. Our meta-analysis aimed to assess the efficacy and safety of perioperative preemptive analgesia with non-steroidal anti-inflammatory drugs in patients with lumbar spine surgery.
METHODS
We searched PubMed, ScienceDirect, the Cochrane Library, and the Web of Science for randomized controlled trials (RCTs) that met the inclusion criteria. A total of 12 clinical studies were included to assess the efficacy and safety of perioperative NSAIDs preemptive analgesia for lumbar spine surgery.
RESULT
Twelve studies, including 845 patients, met the inclusion criteria. The results showed that perioperative receipt of NSAIDs for preemptive analgesia was effective and safe. Patient's postoperative morphine consumption (P < 0.05), visual analog scale (P < 0.05), and numerical rating scale (P < 0.05) were not statistically associated with postoperative complications (P > 0.05).
CONCLUSION
Our findings suggest that NSAIDs are effective and safe for preemptive analgesia in the perioperative period of lumbar spine surgery and that more and better quality RCTs and more in-depth studies of pain mechanics are still needed.

Journal of Pain and Symptom Management Mar 2024Ketamine is a well-characterized anesthetic agent, and subanesthetic ketamine possesses analgesic effects in both acute and chronic pain. (Meta-Analysis)
Meta-Analysis Review
CONTEXT
Ketamine is a well-characterized anesthetic agent, and subanesthetic ketamine possesses analgesic effects in both acute and chronic pain.
OBJECTIVES
A systematic review was performed to ascertain the efficacy and safety of ketamine in treating pain for cancer patients.
METHODS
Eight databases were searched from the inception to March 20th, 2023 to obtain randomized controlled trials (RCTs) on ketamine for treating pain in cancer patients. Two reviewers independently screened studies, extracted the data and assessed the risk of bias of included studies; then, meta-analysis was performed by using Revman 5.3 software and Stata 14.0 software.
RESULTS
Thirty-five studies were included, involving 2279 patients with cancer pain. The results of meta-analysis showed that ketamine could significantly reduce pain intensity. Subgroup analysis revealed that, when compared with control group, ketamine decreased markedly visual analogue scale (VAS) scores in two days after the end of treatment with ketamine, and ketamine administrated by patient controlled epidural analgesia (PCEA) was effective. Meanwhile, ketamine could significantly reduce the number of patient-controlled analgesia (PCA) compressions within 24 hours and morphine dosage. Ketamine could not decrease Ramsay sedation score. Additionally, the adverse events significantly decreased in the ketamine group, including nausea and vomiting, constipation, pruritus, lethargy, uroschesis, hallucination, and respiratory depression. In addition, compared with the control group, ketamine could reduce Hamilton depression scale (HAMD) score and relieve depressive symptoms.
CONCLUSION
Ketamine may be used as an effective therapy to relieve cancer pain. However, more rigorously designed RCTs with larger sample sizes are required to verify the above conclusions.

Efficacy and Safety of Bilateral Ultrasound-Guided Erector Spinae Plane Block for Postoperative Analgesia in Spine Surgery: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.
OBJECTIVE
A meta-analysis of randomized controlled trials was conducted to assess efficacy and safety of bilateral ultrasound-guided erector spinae plane block (ESPB) for postoperative analgesia in patients receiving spine surgery.
METHODS
PubMed, Embase, and CENTRAL databases were searched by 2 reviewers independently to identify randomized controlled trials evaluating the efficacy of ultrasound-guided ESPB for pain management in patients undergoing spine surgery. For meta-analysis, mean difference (MD) and 95% confidence interval (CI) were selected for continuous data, and risk ratio (RR) and 95% CI were selected for dichotomous variables.
RESULTS
A total of 25 randomized controlled trials including 1917 patients (873 in ESPB group and 874 in control group) were eligible for inclusion. At rest, ESPB was associated with significantly lower pain intensity at 0, 2, 4, 6, 8, 12, 24, and 48 hours compared with the control group. During movement, ESPB was associated with significantly lower pain intensity at 0, 4, 6, 8, 12, 24, and 48 hours compared with the control group. Significantly reduced opioid consumption (MD = -6.29, 95% CI [-8.16, 4.41], P < 0.001), prolonged time for first rescue analgesia (MD = 7.51, 95% CI [3.47, 11.54], P < 0.001), fewer patients needing rescue analgesia (RR = 0.34, 95% CI [0.28, 0.43], P < 0.0001), improved patient satisfaction (MD = 1.34, 95% CI [0.88, 1.80], P < 0.001), and shorter length of hospital stay (MD = -0.38, [95% CI -0.50, -0.26], P < 0.001) were demonstrated after use of ESPB. Additionally, ESPB was associated with decreased risks of any adverse event (RR = 0.51, 95% CI [0.43, 0.60], P < 0.001) and postoperative nausea and vomiting events (RR = 0.39, 95% CI [0.31, 0.49], P < 0.001).
CONCLUSIONS
Ultrasound-guided ESPB is an effective adjunctive technique with good tolerability for multimodal analgesia in management of pain in patients undergoing spine surgery.
