Drugs for relief of pain in patients with sciatica: systematic review and meta-analysis.

ABSTRACT:

Objective

To investigate the efficacy and tolerability of analgesic and adjuvant pain drugs typically administered in primary care for the management of patients with sciatica.

Design

Systematic review. Data source International Pharmaceutical Abstracts, PsycINFO, Medline, Embase, Cochrane Central Register of Clinical Trials (CENTRAL), CINAHL, and LILACS.

Study selection

Randomised controlled trials assessing the efficacy and tolerability of drugs versus placebo or other treatment for sciatica.

Data extraction

Two independent reviewers extracted data and assessed methodological quality using the PEDro scale. Pain and disability outcomes were converted to a common 0 to 100 scale. Data were pooled with a random effects model, and the GRADE approach was used in summary conclusions.

Results

Twenty three published reports met the inclusion criteria. The evidence to judge the efficacy of non-steroidal anti-inflammatory drugs (NSAIDs), corticosteroids, antidepressants, anticonvulsants, muscle relaxants, and opioid analgesics ranged from moderate to low quality. Most of the pooled estimates did not favour the active treatment over placebo. The pooled results of two trials of corticosteroids (mean difference in overall and leg pain -12.2, 95% confidence interval -20.9 to -3.4) and a single trial of the anticonvulsant gabapentin for chronic sciatica (mean difference in overall pain relief -26.6, -38.3 to -14.9) showed some benefits but only in the short term. The median rate of adverse events was 17% (interquartile range 10-30%) for the active drugs and 11% (3-23%) for placebo. Trial limitations included failure to use validated outcome measures, lack of long term follow-up, and small sample size.

Conclusions

As the existing evidence from clinical trials is of low quality, the efficacy and tolerability of drugs commonly prescribed for the management of sciatica in primary care is unclear.

Project description:IntroductionOrthopedic procedures have been associated with increased pain, making perioperative analgesia a major clinical concern. We assessed the efficacy and safety of intravenous parecoxib administration during the perioperative period for postoperative pain relief after orthopedic surgery in adults.MethodsPubMed, Cochrane Library, EMBASE, and clinicaltrial.gov were searched from inception to 23 August 2021 without language restrictions. Randomized controlled trials comparing intravenous parecoxib with placebo or another active treatment for acute postoperative pain in adults after orthopedic surgery were included. The primary outcomes were the pain scores and cumulative morphine consumption. The secondary outcomes included the proportion of patients requiring rescue analgesics and the incidence of adverse events. The meta-analysis followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines and was registered on the International Prospective Register of Systematic Reviews Registration (PROSPERO).ResultsTwenty-seven trials (n = 2840) from more than 20 countries involving six types of orthopedic surgery met the inclusion criteria. Compared with placebo, intravenous parecoxib administration led to reductions in postoperative resting pain scores at 6, 12, 24, and 48 h [mean difference (MD) -0.87, 95% confidence interval [CI] -1.71 to -0.03; MD -0.86, 95% CI -1.26 to -0.46; MD -0.57, 95% CI -0.84 to -0.31; MD -0.40, 95% CI -0.69 to -0.11, respectively], postoperative movement pain scores at 24 and 48 h (MD -0.66, 95% CI -1.14 to -0.19; MD -0.78, 95% CI -1.16 to -0.39, respectively), cumulative morphine consumption (MD -11.30 mg, 95% CI -14.79 to -7.81 mg), and the proportion of patients requiring rescue analgesia (relative risk 0.83, 95% CI 0.77-0.89). There was no difference in the incidence of adverse events between groups.ConclusionLow to moderate evidence indicates that parecoxib might be an effective and safe analgesic in perioperative orthopedic settings. It relieves postoperative orthopedic pain while sparing opioid analgesic consumption without increasing the incidence of adverse events.Prospero registrationCRD42021274939.

Project description:BackgroundEffective pain control is crucial to optimise the success of medical procedures. Immersive virtual reality (VR) technology could offer an effective non-invasive, non-pharmacological option to distract patients and reduce their experience of pain. We aimed to evaluate the efficacy of Immersive virtual reality (VR) technology in reducing patient's pain perception during various medical procedures by conducting a systematic review and meta-analysis.MethodsWe searched MEDLINE, EMBASE, CENTRAL, CINAHL, and SIGLE until December 2022 for all randomised clinical trials (RCT) evaluating any type of VR in patients undergoing any medical procedure. We conducted a random effect meta-analysis summarising standardised mean differences (SMD) with 95% confidence intervals (CI). We evaluated heterogeneity using I 2 and explored it using subgroup and meta-regression analyses.ResultsIn total, we included 92 RCTs (n = 7133 participants). There was a significant reduction in pain scores with VR across all medical procedures (n = 83, SMD - 0.78, 95% CI - 1.00 to - 0.57, I 2 = 93%, p = < 0.01). Subgroup analysis showed varied reduction in pain scores across trial designs [crossover (n = 13, SMD - 0.86, 95% CI - 1.23 to - 0.49, I 2 = 72%, p = < 0.01) vs parallel RCTs (n = 70, SMD - 0.77, 95% CI - 1.01 to - 0.52, I 2 = 90%, p = < 0.01)]; participant age groups [paediatric (n = 43, SMD - 0.91, 95% CI - 1.26 to - 0.56, I 2 = 87%, p = < 0.01) vs adults (n = 40, SMD - 0.66, 95% CI - 0.94 to - 0.39, I 2 = 89%, p = < 0.01)] or procedures [venepuncture (n = 32, SMD - 0.99, 95% CI - 1.52 to - 0.46, I 2 = 90%, p = < 0.01) vs childbirth (n = 7, SMD - 0.99, 95% CI - 1.59 to - 0.38, I 2 = 88%, p = < 0.01) vs minimally invasive medical procedures (n = 25, SMD - 0.51, 95% CI - 0.79 to - 0.23, I 2 = 85%, p = < 0.01) vs dressing changes in burn patients (n = 19, SMD - 0.8, 95% CI - 1.16 to - 0.45, I 2 = 87%, p = < 0.01)]. We explored heterogeneity using meta-regression which showed no significant impact of different covariates including crossover trials (p = 0.53), minimally invasive procedures (p = 0.37), and among paediatric participants (p = 0.27). Cumulative meta-analysis showed no change in overall effect estimates with the additional RCTs since 2018.ConclusionsImmersive VR technology offers effective pain control across various medical procedures, albeit statistical heterogeneity. Further research is needed to inform the safe adoption of this technology across different medical disciplines.

Project description:IntroductionLow back pain accounts for more disability than any other musculoskeletal condition and is associated with severe economic burden. Patients commonly present with negative beliefs about low back pain and this can have detrimental effects on their health outcomes. Providing evidence-based, patient-centred education that meets patient needs could help address these negative beliefs and alleviate the substantial low back pain burden. The primary aim of this review is to investigate the effectiveness of patient education materials on immediate process, clinical and health system outcomes.Methods and analysisThe search strategy was developed in collaboration with a librarian and systematic searches will be performed in MEDLINE, EMBASE, CINAHL, PsycINFO and SPORTDiscus. We will also search trial registries and grey literature through the OpenGrey database. Study selection will include a title and abstract scan and full-text review by two authors. Only randomised controlled trials will be included in this review. Trials must include patients with low back pain or sciatica and investigate educational interventions with at least one of the following contrasts: (1) education alone versus no intervention; (2) education alone versus another intervention; (3) education in addition to another intervention versus the same intervention with no education. Data extraction, risk of bias and grading of the quality of evidence will be performed independently by two reviewers. Risk of bias will be assessed using the PEDro scale, and the quality of evidence will be assessed with the Grades of Recommendation, Assessment, Development and Evaluation approach. A random-effects model will be used for each contrast, and results will be pooled if the participants, interventions, and outcomes are homogeneous. If heterogeneity is high (I2 >75%), we will evaluate the magnitude and direction of the differences in effect sizes across studies to determine if it remains reasonable to pool the results. Analyses of acute and subacute low back pain (less than 12 weeks duration) will be performed separately from chronic low back pain (12 weeks or greater duration). Likewise, analyses of short-term (less than 6 months) and long-term (6 months or greater) follow-up will be performed separately. Subgroup analyses will be performed on non-specific low back pain, sciatica and mixed populations.Ethics and disseminationEthical approval is not required for this review. This study, along with its results, will be published in a peer-reviewed journal.
