The efficacy and safety of parecoxib for reducing pain and opioid consumption following total knee arthroplasty: A meta-analysis of randomized controlled trials

Erector spinae plane block level does not impact analgesic efficacy in enhanced recovery for lumbar spine surgery

BACKGROUND CONTEXT

Postoperative pain control following spine surgery can be difficult. The Enhanced Recovery After Surgery (ERAS) programs use multimodal approaches to manage postoperative pain. While an erector spinae plane block (ESPB) is commonly utilized, the ideal distance for injection from the incision, referred to as the ES (ESPB to mid-surgical level) distance, remains undetermined.

PURPOSE

We evaluated the impact of varying ES distances for ESPB on Numerical Rating Scale (NRS) measures of postoperative pain within the ERAS protocol.

STUDY DESIGN/SETTING

Retrospective observational study.

PATIENT SAMPLE

Adult patients who underwent elective lumbar spine fusion surgery.

OUTCOME MEASURES

Primary outcome measures include the comparative postoperative NRS scores across groups at immediate (T1), 24 (T2), 48 (T3), and 72 (T4) hours postsurgery. For secondary outcomes, a propensity matching analysis compared these outcomes between the ERAS and non-ERAS groups, with opioid-related recovery metrics also assessed.

METHODS

All included patients were assigned to one of three ERAS groups according to the ES distance: Group 1 (G1, ES > 3 segments), Group 2 (G2, ES = 2-3 segments), and Group 3 (G3, ES<2 segments). Each patient underwent a bilateral ultrasound-guided ESPB with 60 mL of diluted ropivacaine or bupivacaine.

RESULTS

Patients within the ERAS cohort reported mild pain (NRS < 3), with no significant NRS variation across G1 to G3 at any time. Sixty-five patients were matched across ERAS and non-ERAS groups. The ERAS group exhibited significantly lower NRS scores from T1 to T3 than the non-ERAS group. Total morphine consumption during hospitalization was 26.7 mg for ERAS and 41.5 mg for non-ERAS patients. The ERAS group resumed water and food intake sooner and had less postoperative nausea and vomiting.

CONCLUSIONS

ESPBs can be effectively administered at or near the mid-surgical level to the low thoracic region for lumbar spine surgeries. Given challenges with sonovisualization, a lumbar ESPB may be preferred to minimize the risk of inadvertent pleural injury.

Association of peri-operative prescription of non-steroidal anti-inflammatory drugs with continued prescription of opioids after total knee arthroplasty: a retrospective claims-based cohort study

Non-steroidal anti-inflammatory drugs (NSAIDs) are one of the mainstays of multimodal pain management. While effective for acute pain control, recent pre-clinical evidence has raised concerns regarding an association between NSAIDs and chronic pain and potential opioid use. Our objective was to explore the association between peri-operative use of prescription NSAIDs and the need for continued opioid prescriptions lasting 90-180 days in previously opioid-naïve patients undergoing total knee arthroplasty. A database of health claims in the USA was used to identify all opioid-naïve adult patients who underwent primary knee arthroplasty between January 2010 and October 2021. We evaluated the magnitude of association between peri-operative prescription NSAID claims and claims for opioids at 90 days postoperatively using multivariable logistic regression models. Secondary outcomes included: the magnitude of association between peri-operative NSAID prescription and claims for opioids at 180 days postoperatively; and identifying other potential factors associated with opioid claims at 90 days postoperatively. After risk adjustment using multivariable logistic regression models in the 789,736-patient cohort, the adjusted odds ratio (95%CI) for a continuous claim of opioids at 90 and 180 days postoperatively among patients with a peri-operative NSAID prescription within 30 days was 1.32 (1.30-1.35), p < 0.001; and 1.12 (1.10-1.15), p < 0.001, respectively. This estimate of effect remained robust at 90 days after accounting for known potential confounders, including pre-existing knee pain and acute postoperative pain severity. Similar analysis of other pain medications (e.g. paracetamol) did not detect such an association. This population-based cohort study suggests that peri-operative prescription NSAID use may be associated with continued opioid prescription claims at 90 and 180 days after knee arthroplasty, even after adjusting for other observed covariates for continuous opioid claims. These novel findings can inform clinical decision-making for post-surgical pain management, risk-benefit discussions with patients and future research.

The Efficacy of the Combination of Continuous Femoral Nerve Block and Intravenous Parecoxib on Rehabilitation in Patients Undergoing Total Knee Arthroplasty: A Double-Blind, Randomized Clinical Trial

BACKGROUND AND AIM

The optimal strategy for the management of postoperative pain after total knee arthroplasty (TKA) remains challenging, while its treatment is crucial to increase patients' outcomes. This study aimed to investigate the effects of parecoxib as add-on therapy, in a standard postoperative pain management protocol, represented by the continuous femoral nervous block. We studied its influence on rehabilitation indices and pain scores in patients undergoing TKA.

MATERIAL AND METHODS

This is a single-center, prospective, double-blind, randomized, placebo-controlled trial. All patients were operated with the use of subarachnoid anesthesia, and divided into two groups for postoperative analgesia. Both groups received a continuous femoral nerve block. One of the groups received intravenous parecoxib, while the other received a placebo. The primary investigated outcome was the range of motion (ROM). Recordings were noted at different times postoperatively. Bromage score (BS), visual analog scale (VAS), and the State-Trait Anxiety Inventory (STAI) were also studied.

RESULTS

A total of 90 patients were included and analyzed. ROM was significantly better (p<0.001) and pain scores were significantly lower (p=0.007) in the parecoxib group. No statistically significant difference was found with regard to BS between the two groups. A significant correlation was found between ROM and VAS pain scores at 12 hours (p=0.02), while ROM was inversely correlated with STAI postoperatively.

CONCLUSIONS

The use of intravenous parecoxib is effective in improving rehabilitation indices and provides decreased postoperative pain scores after TKA.

Association between anxiety and metabolic syndrome: An updated systematic review and meta-analysis

Objective

Previous studies have demonstrated an association between anxiety and metabolic syndrome (MetS). However, the association is still controversial. This updated meta-analysis aimed to reanalyze the association between anxiety and MetS.

Methods

We comprehensively searched PubMed, Embase and Web of Science for all related studies published before January 23, 2023. Observational studies that informed effect size with 95% confidence interval (CI) for the association between anxiety and MetS were included. According to heterogeneity between studies, fixed or random effects models were applied to calculate the pooled effect size. Publication bias was examined by funnel plots.

Results

The research included 24 cross-sectional studies: 20 studies used MetS as the dependent variable with a pooled OR of 1.07 (95% CI: 1.01-1.13) and four studies used anxiety as the dependent variable with a pooled OR of 1.14 (95% CI: 1.07-1.23). Three cohort studies were found: two studies detected the association of baseline anxiety with the risk of MetS, one of the studies demonstrated a significant association, but a similar result was not found in another study; one study showed no significant association between baseline MetS and the risk of anxiety.

Conclusion

Cross-sectional studies indicated an association between anxiety and MetS. The results from cohort studies are still inconsistent and limited. More large-scale prospective studies are needed to further reveal the causal relationship of anxiety with MetS.

The efficacy of parecoxib in improving pain after total knee or total hip arthroplasty: Systematic review and meta-analysis

BACKGROUND

The cyclooxygenase-2 (COX-2) selective inhibitor parecoxib is widely used in the treatment of pain and inflammation. Parecoxib has been adopted for use for postoperative analgesia following a range of surgical procedures (orthopedic, general, gynecological, and dental surgery). Total knee or total hip arthroplasty (THA) surgery is mostly done in older patients, so postoperative analgesics need to be used more carefully, and the safety and efficacy of parecoxib in this type of surgery need to be further verified. The aim of this study was to investigate the effects of parecoxib on patient safety, cumulative morphine consumption and was at 24 and 48 hours in the analgesic treatment of total knee or THA for meta-analysis and systematic review, with few studies in this area so far.

METHODS

We searched the Online Database Cochrane Library, PubMed, Web of Science, EMBASE, and CBM (SinoMed), CNKI, VIP, WANFANG up to January 2021. According to the value of I2, the random-effect model or fixed-effect model was supposed to combine data from studies, respectively. Publication bias was assessed through funneling plot and Beggs test. Review Manager 5.3 and Stata 16.0 software were applied to perform the statistical analyses.

RESULTS

Eleven RCTs which involved 1690 participants were included in this study. The meta-analysis indicated parecoxib sodium could not significantly reduce the incidence of adverse events after total knee or THA compared with placebo. There was no statistical significance in incidence of nausea and vomiting. 24 hours resting VAS score was statistically significant between the group. The 48-hour resting VAS scores did not indicate a significant difference between the groups.

CONCLUSION

Parecoxib can reduce the incidence of adverse events after total knee or total hip surgery to some extent but cannot reduce the incidence of nausea and vomiting. Twenty-four hour postoperative analgesia is better than placebo, but 48 hours after operation analgesia is the same as placebo.

Intravenous Parecoxib for Pain Relief after Orthopedic Surgery: A Systematic Review and Meta-analysis

INTRODUCTION

Orthopedic 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.

METHODS

PubMed, 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).

RESULTS

Twenty-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.

CONCLUSION

Low 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.

Pain management after total knee arthroplasty: PROcedure SPEcific Postoperative Pain ManagemenT recommendations

BACKGROUND

The PROSPECT (PROcedure SPEcific Postoperative Pain ManagemenT) Working Group is a global collaboration of surgeons and anaesthesiologists formulating procedure-specific recommendations for pain management after common operations. Total knee arthroplasty (TKA) is associated with significant postoperative pain that is difficult to treat. Nevertheless, pain control is essential for rehabilitation and to enhance recovery.

OBJECTIVE

To evaluate the available literature and develop recommendations for optimal pain management after unilateral primary TKA.

DESIGN

A narrative review based on published systematic reviews, using modified PROSPECT methodology.

DATA SOURCES

A literature search was performed in EMBASE, MEDLINE, PubMed and Cochrane Databases, between January 2014 and December 2020, for systematic reviews and meta-analyses evaluating analgesic interventions for pain management in patients undergoing TKA.

ELIGIBILITY CRITERIA

Each randomised controlled trial (RCT) included in the selected systematic reviews was critically evaluated and included only if met the PROSPECT requirements. Included studies were evaluated for clinically relevant differences in pain scores, use of nonopioid analgesics, such as paracetamol and nonsteroidal anti-inflammatory drugs and current clinical relevance.

RESULTS

A total of 151 systematic reviews were analysed, 106 RCTs met PROSPECT criteria. Paracetamol and nonsteroidal anti-inflammatory or cyclo-oxygenase-2-specific inhibitors are recommended. This should be combined with a single shot adductor canal block and peri-articular local infiltration analgesia together with a single intra-operative dose of intravenous dexamethasone. Intrathecal morphine (100 μg) may be considered in hospitalised patients only in rare situations when both adductor canal block and local infiltration analgesia are not possible. Opioids should be reserved as rescue analgesics in the postoperative period. Analgesic interventions that could not be recommended were also identified.

CONCLUSION

The present review identified an optimal analgesic regimen for unilateral primary TKA. Future studies to evaluate enhanced recovery programs and specific challenging patient groups are needed.

Associations of Multimodal Analgesia With Postoperative Pain Trajectories and Morphine Consumption After Hepatic Cancer Surgery

Background

This study aimed to investigate the influential factors of postoperative pain trajectories and morphine consumption after hepatic cancer surgery with a particular interest in multimodal analgesia.

Methods

Patients receiving hepatic cancer surgery at a tertiary medical center were enrolled between 2011 and 2016. Postoperative pain scores and potentially influential factors like patient characteristics and the analgesic used were collected. Latent curve analysis was conducted to investigate predictors of postoperative pain trajectories and a linear regression model was used to explore factors associated with postoperative morphine consumption.

Results

450 patients were collected, the daily pain scores during the first postoperative week ranged from 2.0 to 3.0 on average. Male and higher body weight were associated with more morphine consumption (both P < 0.001) but reduced morphine demand was noted in the elderly (P < 0.001) and standing acetaminophen users (P = 0.003). Longer anesthesia time was associated with higher baseline pain levels (P < 0.001). In contrast, male gender (P < 0.001) and standing non-steroidal anti-inflammatory drugs (NSAIDs) use (P = 0.012) were associated with faster pain resolution over time.

Conclusions

Multimodal analgesia with standing acetaminophen and NSAIDs had benefits of opioid-sparing and faster pain resolution, respectively, to patients receiving hepatic cancer surgery.

Reducing opioid usage in total knee arthroplasty postoperative pain management: a literature review and future directions

Total knee arthroplasty (TKA) is a common orthopedic surgery performed with a projected 3.5 million procedures to be done by 2030. Current postoperative pain management for TKA is insufficient, as it results in extensive opioid consumption and functional decline postoperatively. This study identifies the best practices for postoperative TKA pain management through a literature review of the last three years. Studies utilizing interventional techniques (local infiltration analgesia, nerve blocks) and pharmacologic options were reviewed on PubMed, Embase, Ovid Medline and Scopus. Primary outcomes analyzed were the effect of different analgesic approaches on pain reduction, opioid use reduction and improvements in functional mobility or quadriceps strength postoperatively. Additionally, this paper explores the use of cooled radiofrequency ablation, a minimally invasive therapy, for preoperative and postoperative TKA pain management.

Perioperative Outcomes of Patients Who Were Not Candidates for Additional Nonsteroidal Anti-inflammatory Drugs in a Multimodal Pain Control Regimen for Total Knee Arthroplasty

Backgroud

Postoperative pain following total knee arthroplasty (TKA) may hamper patients from a rapid recovery and increase perioperative blood loss and stress on the cardiovascular system. Therefore, our objective was to assess perioperative outcomes after TKA in patients who were not candidates for the additional nonsteroidal anti-inflammatory drugs (NSAIDs) in a multimodal pain control regimen.

Methods

Propensity score matching for age, sex, body mass index, American Society of Anesthesiologists class, and preoperative hemoglobin level was conducted on patients undergoing unilateral TKA, and thereby 52 patients remained in each group. The control group comprised patients who received parenteral parecoxib every 12 hours during the first 48 hours after TKA. The No-NSAIDs group did not receive NSAIDs because of known contraindications. Identical postoperative pain control including intravenous patient-controlled analgesia was applied for all patients. Visual analog scale (VAS) score for pain, knee flexion, blood loss, serum cardiac troponin-T (cTnT), and length of stay (LOS) were determined.

Results

The No-NSAIDs group had significantly higher VAS scores in 6–96 hours and consumed more morphine at 24 hours and 48 hours after the surgery than the control group. The No-NSAIDs group had significantly less knee flexion at 48 hours (p = 0.045) and tended to have more emesis and longer LOS than the control group. The blood loss of the No-NSAIDs and control group was 552.52 mL and 397.65 mL (p = 0.02), respectively, and blood transfusion rate was 23.1% and 17.3% (p = 0.63), respectively. The cTnT of the No-NSAIDs group rose over the first 48 hours and was significantly higher than that of the control group at 48 hours.

Conclusions

Patients who were not candidates for NSAIDs had significantly higher pain scores and consumed more morphine after TKA. They also tended to have greater blood loss and the rising of cardiac biomarkers during the first 48 hours after TKA. Hence, these patients may benefit from supplementary analgesia and appropriate perioperative monitoring.

A randomized controlled trial comparing the efficacies of ketorolac and parecoxib for early pain management after total knee arthroplasty

BACKGROUND

Nonsteroidal anti-inflammatory drugs (NSAIDs) are widely used to reduce pain after orthopedic surgery. Currently, selective COX-2 inhibitors can provide effective pain reduction with less platelet inhibition compared with conventional NSAIDs. We aimed to compare the analgesic effect and perioperative blood loss (PBL) after total knee arthroplasty (TKA) between ketorolac and parecoxib administration.

METHODS

We conducted a prospective randomized controlled study of 100 unilateral TKAs. The ketorolac group of 50 patients received an intraoperative periarticular injection (PAI) with 100 mg of bupivacaine and 30 mg of ketorolac. Afterwards, 30 mg of ketorolac was intravenously injected every 12 h until 48 h. In the parecoxib group of 50 patients, 20 mg of parecoxib was added to PAI, and the first intravenous dose was 20 mg followed by 40 mg every 12 h. The primary outcomes were visual analog scales (VASs) of postoperative pain, amount of morphine consumption, PBL, and blood transfusion rate.

RESULTS

The ketorolac group had a significantly lower VAS pain score than the parecoxib group at 6 h after TKA (2.38 ± 2.52 vs. 4.12 ± 2.86, P < 0.01). Thereafter, the VAS of both groups and total morphine consumption at 24 and 48 h were comparable. The PBLs of the ketorolac and parecoxib groups were 529.72 ± 263.02 and 402.40 ± 191.47 ml, respectively (P = 0.01). However, the blood transfusion rates between groups were not different.

CONCLUSION

Parecoxib provides comparable analgesic effects to ketorolac. Additionally, perioperative use of parecoxib is safe and is associated with significantly less blood loss after TKA.

The Efficacy and Safety of Nonsteroidal Anti-Inflammatory Drugs in Total Joint Arthroplasty: Systematic Review and Direct Meta-Analysis

BACKGROUND

Nonsteroidal anti-inflammatory drugs (NSAIDs) have become widely used to manage perioperative pain following total joint arthroplasty (TJA). The purpose of our study is to evaluate the efficacy and safety of NSAIDs in support of the combined clinical practice guidelines of the American Association of Hip and Knee Surgeons, American Academy of Orthopaedic Surgeons, Hip Society, Knee Society, and American Society of Regional Anesthesia and Pain Management.

METHODS

Databases including MEDLINE, EMBASE, and the Cochrane Central Registry of Controlled Trials were searched for studies published prior to November 2018 on NSAIDs in TJA. Studies included after a systematic review evaluated through direct comparisons and/or meta-analysis, including qualitative and quantitative heterogeneity testing, to evaluate effectiveness and safety of NSAIDs.

RESULTS

After critical appraisal of 2921 publications, 25 articles represented the best available evidence for inclusion in the analysis. Oral selective cyclooxygenase (COX)-2 and non-selective NSAIDs and intravenous ketorolac safely reduce postoperative pain and opioid consumption during the hospitalization for primary TJA. Administration of an oral selective COX-2 NSAID reduced postoperative opioid consumption after discharge from TKA.

CONCLUSION

Strong evidence supports the use of an oral selective COX-2 or non-selective NSAID and intravenous ketorolac as adjunctive medications to manage postoperative pain during the hospitalization for TJA. Although no safety concerns were observed, prescribers need to remain vigilant when prescribing NSAIDs.

Proximal versus distal adductor canal blocks for total knee arthroplasty: A protocol for randomized controlled trial

BACKGROUND

Currently, there remains a paucity of literature about the efficiency of proximal adductor canal block (PACB) versus distal adductor canal block (DACB) for pain management after total knee arthroplasty (TKA). The purpose of this study is to perform a randomized controlled trial to compare the efficiency of PACB versus DACB for early postoperative pain treatment after TKA.

METHODS

This study is a 2-arm, parallel-group, randomized controlled trial that is conducted at a single university hospital in China. Subjects presenting for unilateral TKA are randomized in a 1:1 ratio to either a PACB or DACB group. The primary outcome of this noninferiority study is opioid consumption within the first 24 hours following surgery. Secondary outcomes include quadriceps strength, pain scores, distance ambulated, and patient satisfaction. Continuous variables are compared using Student t test.

RESULTS

This clinical trial is expected to provide evidence of whether the PACB and DACB provide similar analgesia after TKA.

TRIAL REGISTRATION

This study protocol was registered in Research Registry (researchregistry5440).

Postoperative Pain Management in Total Knee Arthroplasty

Total knee arthroplasty (TKA) is one of the most common surgeries performed to relieve joint pain in patients with end‐stage osteoarthritis or rheumatic arthritis of the knee. However, TKA is followed by moderate to severe postoperative pain that affects postoperative rehabilitation, patient satisfaction, and overall outcomes. Historically, opioids have been widely used for perioperative pain management of TKA. However, opioids are associated with undesirable adverse effects, such as nausea, respiratory depression, and retention of urine, which limit their application in daily clinical practice. The aim of this review was to discuss the current postoperative pain management regimens for TKA. Our review of the literature demonstrated that multimodal analgesia is considered the optimal regimen for perioperative pain management of TKA and improves clinical outcomes and patient satisfaction, through a combination of several types of medications and delivery routes, including preemptive analgesia, neuraxial anesthesia, peripheral nerve blockade, patient‐controlled analgesia and local infiltration analgesia, and oral opioid/nonopioid medications. Multimodal analgesia provides superior pain relief, promotes recovery of the knee, and reduces opioid consumption and related adverse effects in patients undergoing TKA.
