Analgesic Efficacy of Ropivacaine Infiltration on Early Post-Tonsillectomy Pain in Pediatrics.

OBJECTIVE: To assess the analgesic efficacy of ropivacaine infiltration in the tonsillar fossa among pediatric patients undergoing tonsillectomy. DATA SOURCES: PubMed, Scopus, Web of Science, and CENTRAL. REVIEW METHODS: Eligible randomized controlled trials (RCTs) were assessed for bias using Cochrane's risk of bias tool (version 2). Our primary outcome was postoperative pain within 24 h, and secondary outcomes included operative time, intraoperative blood loss, time to first analgesia, bleeding, and nausea/vomiting. Data were pooled as mean difference, standardized mean difference, and risk ratio with a 95% confidence interval. RESULTS: Our review included 11 RCTs, with a total of 712 patients. The quality of studies varied and included low risk (n = 8 RCTs), some concerns (n = 2 RCTs), and high risk (n = 1 RCT) of bias. The primary endpoint of postoperative pain across all time points was significantly reduced in the ropivacaine group compared with the placebo group. Trial sequential analysis (TSA) of the postoperative pain depicted conclusive evidence and unnecessity for further RCTs. The mean operative time was significantly reduced in the ropivacaine group compared with the placebo group. However, there was no significant difference between both groups regarding additional clinical (i.e., mean intraoperative blood loss and mean time to first analgesia) and safety (i.e., rates of bleeding and nausea/vomiting) outcomes. CONCLUSION: This systematic review and meta-analysis demonstrated the safety and postoperative analgesic efficacy of ropivacaine versus placebo among pediatric patients undergoing tonsillectomy. There was no significant difference between both groups regarding intraoperative blood loss, time to first analgesia, and rate of postoperative bleeding. LEVEL OF EVIDENCE: 1 Laryngoscope, 134:3018-3029, 2024.

Coblation tonsillectomy versus laser tonsillectomy: a systematic review and meta-analysis of randomized controlled trials.

AIM: This systematic review and meta-analysis of randomized controlled trials (RCTs) evaluated coblation versus laser (carbon dioxide and diode) tonsillectomy, with regard to various surgical and clinical outcomes. METHODS: We searched PubMed, CENTRAL, Scopus, and Web of Science for relevant from inception until March 2021. We evaluated risk of bias using the Cochrane Collaboration Tool. We summarized the outcomes as risk ratio (RR) or mean difference/standardized mean difference (MD/SMD) with 95% confidence interval (CI). We conducted subgroup analysis based on the day of postoperative pain (day 1, day 7, and day 14) and type of postoperative hemorrhage (reactionary and secondary). In addition, we conducted subgroup analysis according to the type of laser. RESULTS: Five RCTs were analyzed. Three and two RCTs were evaluated as having "some concerns" and "low risk of bias", respectively. Coblation tonsillectomy correlated with lower intraoperative blood loss (MD = -5.08 ml, 95% CI [- 7.33 to - 2.84], P < 0.0001) and lower operative time (MD = - 4.50 min, 95% CI [- 6.10 to - 2.90], P < 0.0001) compared with the laser tonsillectomy. However, there was no significant difference between both groups regarding the postoperative pain score (SMD = - 0.27, 95% CI [- 0.72 to 0.17], P = 0.27) and rate of postoperative hemorrhage (RR = 0.95, 95% CI [0.27-3.40], P = 0.23). Subgroup analysis reported similar insignificant difference between both groups according to the day of postoperative pain and type of postoperative hemorrhage. CONCLUSIONS: Coblation tonsillectomy correlated with a significant reduction in intraoperative blood loss and operative time compared with the laser technique. Nevertheless, these effects do not seem clinically meaningful in surgical practice.

Intraoperative local injection of uterosacral ligaments with ropivacaine during uterine surgery: A systematic review and meta-analysis of randomized controlled trials.

AIM: To perform a systematic review and meta-analysis of all randomized controlled trials that examined the efficacy of intraoperative local injection of the uterosacral ligaments with ropivacaine on postoperative pain and opioids consumption in patients undergoing uterine surgery for hysterectomy/myomectomy. METHODS: PubMed, Scopus, Web of Science and Cochrane Library databases were screened from inception to September 5th, 2020. We appraised the risk of bias using the Cochrane's risk of bias tool. Resting postoperative pain scores and cumulative consumption of postoperative opioids were regarded as continuous data, analyzed using the inverse variance method and reported as standardized mean difference (SMD) and weighted mean difference (MD), respectively, with 95 % confidence intervals (95 % CIs). RESULTS: Five studies met the inclusion criteria comprising 230 patients (117 and 113 patients received ropivacaine and placebo, respectively). The studies had an overall low risk of bias. Resting postoperative pain scores were not significantly different between both groups at 2 h (SMD = -0.30, 95 % CI [-0.70, 0.11], p = 0.15), 12 h (SMD = 0.04, 95 % CI [-0.26, 0.37], p = 0.81) and 24 h (SMD = -0.06, 95 % CI [-0.32, 0.20], p = 0.68). However, the ropivacaine group had significantly reduced cumulative opioid consumption during the first 24 h postoperatively (MD = -9.07, 95 % CI [-14.47, -3.66], p = 0.001). CONCLUSION: Intraoperative local infiltration of uterosacral ligaments with ropivacaine is technically feasible and significantly reduces postoperative opioid consumption in women undergoing gynecologic surgery of the uterus.

The Effect of Iron Supplementation on FGF23 in Chronic Kidney Disease Patients: a Systematic Review and Time-Response Meta-Analysis.

Fibroblast growth factor 23 (FGF23) gene is found to be responsible for autosomal dominant hypophosphatemic rickets, and is highly expressed in chronic kidney disease (CKD) and end-stage renal disease patients with iron deficiency anemia (IDA). We evaluated the efficacy of different iron treatments on FGF23 levels in dialysis-dependent and non-dialysis-dependent CKD patients with IDA. We performed a systematic review and meta-analysis of randomized controlled trials (RCTs) comparing different types of iron treatment versus placebo in CKD patients up to May 2020. We investigated the efficacy of iron treatment on the levels of FGF23 and C-terminal FGF23 (cFGF23) in CKD patients. We estimated weighted mean differences (WMDs) and 95% confidence intervals (CIs) using the random-effects model. Nine studies with 11 arms were included in the meta-analysis. Overall, iron treatment showed a significant reduction in FGF23 levels compared to control group (WMD: - 60.56 pg/ml, 95% CI: - 92.17, - 28.95). Compared to placebo, subgroup analysis showed that oral iron therapy (WMD: - 6.98 pg/ml, 95% CI: - 10.66, - 3.31) was more effective than intravenous (IV) iron therapy (WMD: 4.90 pg/ml, 95% CI: - 12.03, 21.83) on FGF23 levels. There was no significant change in cFGF23 levels between iron treatment and control group (WMD: - 64.72 Ru/ml, 95% CI: - 147.69, 18.25). Subgroup analysis showed that oral iron therapy resulted in a significant reduction in cFGF23 levels compared to control group (WMD: - 150.48 RU/ml, 95% CI: - 151.31, - 149.65). In conclusion, iron treatment was associated with a significant decrease in FGF23 levels in CKD patients.

Ropivacaine versus lidocaine infiltration for postpartum perineal pain: A systematic review and meta-analysis.

AIM: To systematically and meta-analytically examine the efficacy of ropivacaine versus lidocaine infiltration for controlling postpartum perineal pain secondary to spontaneous tear or selective episiotomy. METHODS: We searched four databases from inception to 20-September-2020. We included all relevant randomized and nonrandomized studies and assessed their risk of bias. We pooled data as standardized mean difference (SMD), weighted mean difference (WMD), or odds ratio (OR) with 95 % confidence intervals (95 % CIs). RESULTS: Four studies met the inclusion criteria (one and three studies were nonrandomized and randomized, respectively). There were 405 patients; 205 and 200 patients received lidocaine and ropivacaine, respectively. There was no significant difference between ropivacaine and lidocaine groups with regard to visual analogue scale (VAS) pain scores at suturing (WMD = -0.04, 95 % CI [-0.41, 0.32], P = 0.82), 2 h (SMD = -1.50, 95 % CI [-3.50, 0.50], P = 0.14), and 24 h (SMD = -0.40, 95 % CI [-1.15, 0.34], P = 0.29) post repair of perineal trauma. Proportion of patients with mild VAS pain score ≤3 at 24 h was significantly higher in the ropivacaine group (OR = 4.34, 95 % CI [2.03, 9.29], P < 0.001). Proportion of patients who did not require additional analgesia during the first 24 h post perineal repair did not significantly differ between both groups (OR = 2.44, 95 % CI [0.09, 68.21], P = 0.60). Ropivacaine group achieved higher maternal satisfaction (OR = 7.13, 95 % CI [3.63, 13.99], P < 0.001). CONCLUSIONS: During repair of postpartum perineal trauma, pain efficacy is relatively longer with ropivacaine but safety is not well investigated. High-quality and large-sized studies are needed to consolidate these findings.

Efficacy and safety of topical clascoterone cream for treatment of acne vulgaris: A systematic review and meta-analysis of randomized placebo-controlled trials.

To systematically and meta-analytically pool evidence from randomized placebo-controlled trials that examined the efficacy and safety of topical clascoterone cream in patients with acne vulgaris. Four databases were screened from inception to 10 October 2020. Included studies were assessed for risk of bias. Efficacy outcomes included investigator's global assessment (IGA) treatment success and absolute change in inflammatory lesion counts (ILCs) and noninflammatory lesion counts (NILCs). Safety outcomes included the proportion of patients with any treatment-emergent adverse event (TEAE) as well as incidence of any TEAE, serious adverse events (AEs), AEs related to study drug, AEs leading to study drug discontinuation, nasopharyngitis, headache, oropharyngeal pain, and vomiting. Dichotomous data were analyzed using the risk ratio (RR) and 95% confidence interval (95% CI) whereas continuous data were analyzed using the mean difference (MD) and 95% CI. Review Manager Software version 5.4.1 was used for statistical analysis. Five clinical trials, comprising 2457 patients (1357 and 1100 patients received clascoterone and placebo, respectively) were included. Studies revealed an overall low risk of bias. Clascoterone significantly increased IGA success rates (RR = 2.87, 95% CI [2.11, 3.89], P < .001) and decreased NILCs (MD = -5.64, 95% CI [-8.41, -2.87], P < .01) without substantially impacting the ILCs (MD = -1.82, 95% CI [-5.06, 1.43], P = .27). No significant differences were noted between both groups for all safety outcomes, except for nasopharyngitis which was significantly lower in the clascoterone group (RR = 0.47, 95% CI [0.27, 0.83], P = .01). Topical clascorterone cream is safe and effective in the treatment of acne vulgaris.
