Front Med (Lausanne) 2023; 10:1231570. [PMID: 37529243 PMCID: PMC10387543 DOI: 10.3389/fmed.2023.1231570] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2023] [Accepted: 06/22/2023] [Indexed: 08/03/2023] Open
Abstract
Objective The aim of this study was to systematically review the efficacy and safety of parecoxib and flurbiprofen axetil for perioperative analgesia in children through Bayesian network meta-analysis. Methods We systematically searched PubMed, Embase, Cochrane Library, Web of Science, Sinomed, CNKI, VIP, and Wanfang Data databases on 18 July 2022 to obtain randomized controlled trials comparing perioperative parecoxib or flurbiprofen with placebo or standard treatment for pediatric analgesia. The outcomes were the postoperative pain score and the incidence of adverse events. The Gemtc package of R-4.0.3 and Stata 17.0 were used for Bayesian network meta-analysis. Results We retrieved 942 articles and 49 randomized controlled trials involving 3,657 patients who met the inclusion criteria. Compared with children who received placebo treatment, those who received flurbiprofen axetil had lower pain sores at each time point within 24 h postoperatively, and those who received parecoxib had lower pain sores at each time point within 12 h postoperatively. Compared with children who received tramadol treatment, both the children who received flurbiprofen axetil or parecoxib had lower pain scores at 8 h postoperatively. The ranking results demonstrated that flurbiprofen axetil had significant superiority in reducing pain scores at 2, 4, and 12 h postoperatively, and parecoxib had significant superiority in reducing pain scores at 0, 0.5, 1, 6, 8, and 24 h postoperatively. In terms of safety, compared with children who received placebo, those who received flurbiprofen axetil or parecoxib had a lower incidence of total adverse events and postoperative agitation. Compared with tramadol, flurbiprofen axetil and parecoxib both significantly reduced the incidence of total adverse events and postoperative nausea and vomiting. Compared with flurbiprofen axetil or fentanyl, parecoxib significantly reduced the incidence of postoperative nausea and vomiting. The ranking results showed that parecoxib was advantageous in decreasing the incidence of total adverse events and postoperative nausea and vomiting. Conclusion Flurbiprofen axetil was most effective at reducing pain scores at 2, 4, and 12 h postoperatively. Parecoxib had an advantage in terms of reducing pain scores at 0, 0.5, 1, 6, 8, and 24 h postoperatively, as well as the incidence of total adverse events and postoperative nausea and vomiting.

Examining the efficacy of intravenous ibuprofen and meperidine for preventing post-operative shivering after laparoscopic cholecystectomy with general anesthesia. J Med Life 2023; 16:1041-1046. [PMID: 37900063 PMCID: PMC10600668 DOI: 10.25122/jml-2022-0040] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2022] [Accepted: 12/22/2022] [Indexed: 10/31/2023] Open
Abstract
Postoperative shivering is a common complication that can lead to increased postoperative complications. This study aimed to compare the effectiveness of intravenous ibuprofen and meperidine in preventing shivering following laparoscopic cholecystectomy. A total of 120 patients, aged 20-70 and classified as ASA I-II, were enrolled in this triple-blind clinical trial. The participants were randomly assigned to one of three groups: ibuprofen (800mg IV), meperidine (30 mg), or placebo (normal saline 2 ml), administered 30 minutes before the end of surgery. The occurrence of postoperative shivering was assessed and recorded at regular intervals (0, 5, 10, 15, 30, and 60 minutes after surgery). Additionally, postoperative pain levels were measured using a visual analog scale (VAS), sedation levels were evaluated using the Ramsay Sedation Scale (RSS), and the incidence of postoperative nausea and vomiting was documented. The prevalence and severity of postoperative shivering were not statistically significant between groups. The VAS was significantly lower in the meperidine group than the ibuprofen group throughout the study (p <0.001). The VAS was significantly lower in the ibuprofen group than the placebo group at 0 and 15 minutes after surgery. Although the incidence of nausea was slightly higher in the meperidine group, the difference was not statistically significant (p=0.75). Sedation scores were consistently lower in the ibuprofen group and higher in the meperidine group compared to the other groups (p<0.0001) The meperidine group had a significantly higher sedation score indicative of deep sleepiness (score of 4) than the other groups. Intravenous ibuprofen demonstrated comparable efficacy to meperidine in controlling shivering. Additionally, the incidence of nausea, vomiting, and sleepiness was lower in the intravenous ibuprofen group, suggesting it is a potential alternative to meperidine.

Abstract
BACKGROUND Inflammation plays a key role in the etiology and pathology of postoperative cognitive dysfunction (POCD). Cyclooxygenase (COX)-2 inhibitor parecoxib is used for the treatment of acute pain due to its potent anti-inflammatory and analgesic effects. Herein, we evaluated the efficacy and safety of parecoxib on early POCD in geriatric patients. OBJECTIVE This study was performed to evaluate the efficacy and safety of parecoxib for early postoperative cognitive dysfunction (POCD) in elderly patients. METHODS Comprehensive literature search based on six electronic databases was applied to retrieve all related randomized controlled trials (RCTs). Two independent reviewers screened each article for eligibility according to the predetermined inclusion criteria. The Cochrane's Tool was applied to evaluate the methodological quality of included studies. RevMan 5.3 was used to conduct meta-analysis. RESULTS Eight RCTs comprising a total of 1106 subjects prepared for orthopedic surgical operation were selected. All the identified RCTs were conducted in China. The methodological qualities of included studies were judged to be medium to high. The integrated data showed that perioperative intravenous parecoxib could remarkably reduce the incidence of POCD with improved Mini-Mental State Examination (MMSE) score. Parecoxib could significantly reduce the concentrations of interleukin-6, but results regarding the changes in tumor necrosis factor-alpha, C-reactive protein, and S100β levels remained inconsistent. CONCLUSION Perioperative parecoxib administration is effective in reducing the incidence of POCD and improving the MMSE score compared with control. However, the beneficial effect of parecoxib has been tested only in the Chinese population. Future RCTs in western countries with larger-scale and more comprehensive neurological tests are needed.

Abstract
Transarterial chemoembolization(TACE) is the palliative treatment of choice for patients with unresectable hepatocellular carcinoma (HCC). The 242 patients prospectively enrolled in this study were diagnosed with HCC and received TACE at Sun Yat-Sen University Cancer Center between October 2014 and March 2015. Patients were divided into study and control groups based on whether parecoxib sodium was administered postoperatively. Postoperative pain, body temperature, vomiting, changes in liver function, physical activity level, length of hospital stay, and tumor control were evaluated. Compared to the control group after propensity score matching, the study group presented less severe postoperative fever. The daily maximum temperatures in the study and control groups were 37.39 vs. 37.82°C on postoperative day 1 (P < 0.001), 37.10 vs. 37.51°C on day 2 (P < 0.001), and 36.90 vs. 37.41°C on day 3 (P < 0.001). The study group also exhibited greater physical activity (P < 0.05) and had shorter hospital stays (7.21 days vs. 7.92 days, P = 0.041). There were no differences in pain scores. Thus administration of parecoxib sodium to HCC patients after TACE effectively relieved fever, promoted postoperative recovery, and shortened the hospital stay.

Abstract
The aim of this study was to conduct an overview of systematic reviews that summarizes the results about efficacy and safety from randomized controlled trials involving the various strategies used for postoperative pain management in children. We searched the Cochrane Database of Systematic Reviews, CINAHL, Database of Reviews of Effect, Embase, MEDLINE, and PsycINFO from the earliest date to January 24, 2016. This overview included 45 systematic reviews that evaluated interventions for postoperative pain in children. Out of 45 systematic reviews that investigated various interventions for postoperative pain in children, 19 systematic reviews (42%) presented conclusive evidence of efficacy. Positive conclusive evidence was reported in 18 systematic reviews (40%) for the efficacy of diclofenac, ketamine, caudal analgesia, dexmedetomidine, music therapy, corticosteroid, epidural analgesia, paracetamol, and/or nonsteroidal anti-inflammatory drugs and transversus abdominis plane block. Only one systematic review reported conclusive evidence of equal efficacy that involved a comparison of dexmedetomidine vs morphine and fentanyl. Safety of interventions was reported as conclusive in 14 systematic reviews (31%), with positive conclusive evidence for dexmedetomidine, corticosteroid, epidural analgesia, transversus abdominis plane block, and clonidine. Seven systematic reviews reported equal conclusive safety for epidural infusion, diclofenac intravenous vs ketamine added to opioid analgesia, bupivacaine, ketamine, paracetamol, and dexmedetomidine vs intravenous infusions of various opioid analgesics, oral suspension and suppository of diclofenac, only opioid, normal saline, no treatment, placebo, and midazolam. Negative conclusive statement for safety was reported in one systematic review for caudal analgesia vs noncaudal regional analgesia. More than half of systematic reviews included in this overview were rated as having medium methodological quality. Of 45 included systematic reviews, 10 were Cochrane reviews and they had higher methodological quality than non-Cochrane reviews. As evidence concerning efficacy and safety is inconclusive for most of the analyzed interventions, our review points out the need for more rigorous trials concerning pain management in children.

Abstract
Objective To evaluate the effect of parecoxib on preventing postoperative shivering. Methods Main outcomes were the relative risk (odds ratio, OR) and 95% confidence interval (CI) relative to the incidence of shivering. Results Fourteen trials with 1,175 patients were analyzed. The pooled evidence suggested that parecoxib sodium, given before anesthesia or postoperatively (only 4 cases), had the potential to prevent postoperative shivering (OR = 0.21, 95% CI, 0.16, 0.29). Compared with the placebo, parecoxib sodium significantly lowered the incidence of postoperative shivering as follows: mild shivering [OR = 0.51, 95% CI (0.35, 0.74)]; moderate shivering [OR = 0.28, 95% CI (0.18, 0.45)]; severe shivering [OR = 0.18, 95% CI (0.10, 0.33)]. Compared with placebo, there was no significant association of parecoxib sodium with restlessness [OR = 0.95, 95% CI (0.59, 1.52)] or nausea/vomiting [OR = 0.24, 95% CI (0.09, 0.66)]. In addition, pethidine rescue was used significantly more often in the control group than in the parecoxib sodium group [OR = 0.22, 95% CI (0.09, 0.53)]. Conclusions Parecoxib sodium may be an effective strategy for preventing postoperative shivering.

Abstract
Acetaminophen, nonsteroidal antiinflammatory drugs (NSAIDs), and corticosteroids, historically used in perioperative management, are potent analgesic medications. They primarily inhibit the cyclooxygenase (COX) enzyme, decreasing the synthesis of prostaglandins, and modulating pain and temperature. Acetaminophen does not inhibit this synthesis at the inflammatory site. The primary mechanism of action of corticosteroids involves regulation of nuclear expression of genes involved in inflammatory pathways and other systemic effects. Metaanalyses have added purposeful perioperative indications, clarified misconceptions, and established protocols for administering these drugs. Some indications, doses, clinical considerations, and adverse effects need to be further studied.

Abstract
BACKGROUND Few pharmacokinetic (PK) and pharmacodynamic (PD) data exist for COX-2 selective inhibitors in children. We wished to characterize the PKPD of parecoxib and its active metabolite, valdecoxib, in this population. METHODS Children (n = 59) were randomized to parecoxib 0.25 mg·kg-1 , 1 mg·kg-1 , and 2 mg·kg-1 during tonsillectomy ± adenoidectomy. Samples (4-6 per child) were obtained from indwelling cannula over 6 h. A second group of inpatient children (n = 15) given 1 mg·kg-1 contributed PK data from 6 to 24 h. Pain scores and rescue medication for the first group were recorded postoperatively for up to 24 h. PK data were pooled with those (10 samples/24 h) from a published study of children (n = 38) who underwent surgery. A three-compartment parent and one-compartment metabolite model with first-order elimination was used to describe data using nonlinear mixed effects models. An EMAX model described the relationship between dose and rescue morphine equivalents during recovery. RESULTS Parecoxib PK parameter estimates were CLPARECOXIB 19.1 L·h-1 ·70 kg-1 , V1PARECOXIB 4.2 L·70 kg-1 , Q2PARECOXIB 6.29 L·h-1 ·70 kg-1 , V2PARECOXIB 130 L·70 kg-1 , Q3PARECOXIB 6.02 L·h-1 ·70 kg-1 , and V3PARECOXIB 2.03 L·70 kg-1 . We assumed all parecoxib was metabolized to valdecoxib with CLVALDECOXIB 9.53 L·h-1 ·70 kg-1 and VVALDECOXIB 51 L·70 kg-1 . There was no maturation of clearance over the age span studied. There were no differences in pain scores between groups on waking, discharge, 12 h, or 24 h. There were no differences in analgesia consumption over 24 h between groups for tramadol, fentanyl, and morphine rescue use. Fentanyl and morphine consumption, expressed as morphine equivalents (0.13 mg·kg-1 ) in the 0.25 mg·kg-1 group, was greater than that observed in the 1 or 2 mg·kg-1 groups (0.095 mg·kg-1 ) in PACU. CONCLUSIONS Parecoxib 0.9 mg·kg-1 in a 2-year-old, 0.75 mg·kg-1 in a 7-year-old, and 0.65 mg·kg-1 in a 12-year-old child achieves dose equivalence of 40 mg in a standard 70 kg person. Clearance maturation may occur in infants younger than the current cohort. Parecoxib doses above 1 mg·kg-1 add no additional analgesia.
