OBJECTIVE To collate evidence from randomized controlled trials (RCTs) and nonrandomized controlled trials (NCTs) on the efficacy and safety of vasopressin versus passive control (placebo/no treatment) during myomectomy. METHODS Six information sources were screened until 25-June-2022. The Cochrane Collaboration tool and Newcastle-Ottawa Scale were used to evaluate the risk of bias. Data were summarized as mean difference or risk ratio with 95% confidence interval in a random-effects model. RESULTS Eleven studies, comprising 1067 patients (vasopressin=567 and control=500) were analyzed. For RCTs (n=8), the overall quality included 'high risk' (n=4), 'low risk' (n=2), and 'some concerns' (n=2). For NCTs (n=3), the overall quality included 'good' (n=2) and 'fair' (n=1). The mean intraoperative blood loss, mean difference in hemoglobin level, mean difference in hematocrit level, rate of perioperative blood transfusion, and mean operative time were significantly reduced in favor of the vasopressin group compared with the control group. However, there was no significant difference between both groups regarding the mean hospital stay. Pertaining to safety endpoints, after omission of an outlier study, the rate of drug-related cardiovascular adverse events did not significantly differ between both groups. There was no quantitative evidence of publication bias for the endpoint of intraoperative blood loss. CONCLUSION Among patients undergoing myomectomy, prophylactic administration of vasopressin was largely safe and correlated with significant reductions in intraoperative blood loss and associated morbidities compared with a passive control intervention. Nonetheless, the conclusions should be cautiously interpreted owing to the low-evidence quality and the used doses varied greatly between studies.

OBJECTIVE To evaluate the value of intrauterine platelet-rich concentrates among patients with intrauterine adhesions (IUAs) after hysteroscopic adhesiolysis. METHODS Four different databases (PubMed, Cochrane Library, Scopus, and ISI web of science) were searched for the available studies from inception to November 2021. We selected randomized clinical trials (RCTs) that compared platelet-rich concentrates in the intervention group versus no injection of platelet-rich concentrates in the control group among women with intrauterine adhesions after operative hysteroscopy. Revman software was utilized for performing our meta-analysis. Our primary outcomes were the adhesion score and incidence of recurrence of severe intrauterine adhesions postoperatively. Our secondary outcomes were the clinical pregnancy rate, menstrual flow duration in days, and menstrual flow amount (number of pads). RESULTS Five RCTs met our inclusion criteria with a total number of 329 patients. We found that platelet-rich concentrates were linked to a significant reduction in the postoperative adhesion score (MD = -1.00, 95% CI [-1.68, -0.32], p = 0.004). Moreover, there was a significant reduction in the incidence of severe IUAs recurrence among the platelet-rich concentrates group (7.6%) compared to the control group (23.4%) after hysteroscopy (p = 0.001). The clinical pregnancy rate was significantly increased among the platelet-rich concentrates group (37.1%) in comparison with the control group (20.7%) after hysteroscopic adhesiolysis (p = 0.008). There were significant improvements in the menstrual flow duration and amount among the platelet-rich concentrates group (p < 0.001). CONCLUSIONS Intrauterine placement of platelet-rich concentrates is an effective method for the treatment of intrauterine adhesions after hysteroscopy.

To perform a systematic review and meta-analysis of all randomized controlled trials (RCTs) that evaluated the efficacy and safety of prophylactic tranexamic acid (TXA) versus a control (placebo or no treatment) during hysterectomy for benign conditions. Six databases were screened from inception to January 23, 2022. Eligible studies were assessed for risk of bias. Outcomes were summarized as weighted mean differences and risk ratios with 95% confidence intervals in a random-effects model. Five studies, comprising six arms and 911 patients were included in the study. Two and three studies had an overall unclear and low risk of bias, respectively. Estimated intraoperative blood loss, requirement for postoperative blood transfusion, and requirement for intraoperative topical hemostatic agents were significantly reduced in a prophylactic TXA group when compared with a control group. Moreover, postoperative hemoglobin level was significantly higher in the prophylactic TXA group than in the control group. Conversely, the frequency of self-limiting nausea and vomiting was significantly higher in the prophylactic TXA group than in the control group. There were no significant differences between the groups in terms of surgery duration, hospital stay, and diarrhea rate. All the RCTs reported no incidence of major adverse events in either group, such as mortality, thromboembolic events, visual disturbances, or seizures. There was no publication bias for any outcome, and leave-one-out sensitivity analyses demonstrated stability of the findings. Among patients who underwent hysterectomy for benign conditions, prophylactic TXA appeared largely safe and correlated with substantial reductions in estimated intraoperative blood loss and related morbidities.

OBJECTIVE To conduct a systematic review and meta-analysis of all randomized controlled trials (RCTs) that inspected the efficacy and safety of prophylactic TXA compared with control (placebo/no treatment) among women undergoing vaginal delivery on reducing postpartum blood loss and related morbidities. METHODS Six databases were screened from inception until 06-December-2021. The pooled data were summarized as mean difference or risk ratio, respectively, with 95% confidence interval in a fixed- or random-effects model. RESULTS Sixteen studies comprising 17 RCT treatment arms were included. There were 7075 patients; 3548 and 2537 patients were allocated to prophylactic TXA and control groups, respectively. Overall, the included RCTs had a low risk of bias. Prophylactic TXA correlated with a significant decrease in mean postpartum blood loss and mean change in hemoglobin/hematocrit. Moreover, prophylactic TXA was linked to decreased incidence rates of postpartum hemorrhage, need for blood transfusion, and need for additional uterotonic agents. Nevertheless, prophylactic TXA culminated in significantly higher incidence rates of nausea, vomiting, and diarrhea, all of which were well-tolerated. There was no increased risk of thromboembolic events. Leave-one-out sensitivity analysis confirmed the robustness of efficacy endpoints. There was no publication bias for the endpoint of mean postpartum blood loss. CONCLUSION Among patients undergoing vaginal delivery, prophylactic TXA during active management of third stage of labor (AMTSL) appeared largely safe and correlated with a significant decrease in postpartum blood loss and related morbidities compared with control intervention. Prophylactic TXA should be integrated as a "formal" component of AMTSL among women undergoing vaginal delivery.
