PloS one. 2023;18(11):e0294052
Abstract
BACKGROUND The non-pneumatic anti-shock garment (NASG) is a life-saving device that can help to avoid delays and prevent further complications in the case of obstetric hemorrhage. Although there are many fragmented primary studies on the NASG utilization in Ethiopia, the pooled utilization rate is unknown. In addition, a disagreement was observed among those studies while reporting the associated factors. Therefore, this study was intended to determine the pooled level of NASG utilization and its associated factors among obstetric care providers in Ethiopia. METHODS A total of 51 studies were retrieved from PubMed, Google Scholar, the African Journal of Online, direct open-access journals, and Ethiopian universities' institutional repositories. This study was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. The quality of studies was evaluated using the modified Newcastle-Ottawa quality assessment tool. The data were extracted by two authors independently using Microsoft Excel and analyzed by Stata version 11. A random-effects model was applied to calculate the pooled level of NASG utilization and its associated factors. The PROSPERO registration number for the review is CRD42023414043. RESULT A total of 8 studies comprising 2,575 study participants were involved in this meta-analysis. The pooled utilization rate of NASG was found to be 39.56%. Having NASG training (pooled odds ratio (OR) = 3.99, 95%CI = 2.35, 6.77), good knowledge about NASG (OR = 2.92, 95%CI = 2.04, 4.17), a positive attitude towards NASG (OR = 3.17, 95%CI = 2.10, 4.79), and having ≥ 2 NASGs in the health facility (OR = 10.59, 95%CI = 6.59, 17.01) were significantly associated with NASG utilization. CONCLUSION Utilization of NASG for the treatment of obstetric hemorrhage was low in Ethiopia. To increase its utilization, Ministry of Health should improve the accessibility of NASG at each health facility and increase the Health professionals' knowledge and attitude through in-service and pre-service training.

Abstract
BACKGROUND There is debate on whether uterine gauze packing or intrauterine balloon tamponade is safer and more effective as a surgical management option for treating postpartum hemorrhage. OBJECTIVE This study aimed to compare intra- and postoperative outcomes of intrauterine balloon tamponade and uterine gauze packing in patients with postpartum hemorrhage. STUDY DESIGN A range of databases such as Cochrane and PubMed were searched using terms including "post-partum haemorrhage," "uterine balloon tamponade," and "uterine gauze packing." All observational studies comparing intrauterine balloon tamponade with uterine gauze packing were included. Five studies were identified enrolling 821 adult patients diagnosed with postpartum hemorrhage. Primary outcomes included blood loss volume, success rates, and maternal mortality. Secondary outcomes comprised requiring additional interventions, postoperative hemoglobin levels, and requiring blood transfusions. Fixed and random models were used for analysis. RESULTS Intrauterine balloon tamponade seemed to be a superior option to uterine gauze packing. Intrauterine balloon tamponade was better in reducing intraoperative blood loss, with a statistically significant improvement (P<.0001). Cases managed with intrauterine balloon tamponade seemed to have statistically significant shorter operative time (P=.023) and hospital length of stay (P=.020) in one study. CONCLUSION Intrauterine balloon tamponade remains more effective and safer as a first-line surgical management option for postpartum hemorrhage compared with uterine gauze packing.

Abstract
To evaluate the clinical efficacy, safety, and cost-effectiveness of endometrial ablation or resection (E:A/R) compared to hysterectomy for the treatment of heavy menstrual bleeding (HMB). Literature-search was performed for all the randomized control trials (RCTs) comparing (E:A/R) versus hysterectomy for the treatment of HMB. The literature-search was last updated in November 2022. The primary outcomes were objective and subjective reduction in HMB and patient-satisfaction rates in improving the bleeding symptoms at 1-14 years. The data were analyzed using Review Manager software. Twelve RCTs with 2,028 women (hysterectomy: n=977 vs. E:A/R: n=1,051) were included. Hysterectomy was compared with endometrial ablation in 5 studies, endometrial resection in 5 studies, and both ablation and resection in 2 studies. The meta-analysis revealed that the hysterectomy group showed improved patient-reported and objective bleeding-symptoms more than those of the EA/R group with risk ratios (RR) of (MD, 0.75; 95% CI, 0.71 to 0.79) and (MD, 44.00; 95% CI, 36.09 to 51.91), respectively. The patient-satisfaction was higher post-hysterectomy up to a follow-up period of 2 years (RR, 0.90; 95% CI, 0.86 to 0.94) but this effect was absent with long term follow-up. This meta-analysis shows that E:A/R offers alternatives to hysterectomy. Although both procedures are highly effective, safe, and improve the quality of life, hysterectomy is significantly superior at improving the bleeding symptoms and patient satisfaction up to two-years. However, hysterectomy is associated with longer operating times and recovery periods and has a higher rate of postoperative complications. The initial cost of E:A/R is less than that of hysterectomy but further surgical requirements are common, therefore there is no difference in the cost for the long term follow-up.

Hafermann, J., Silas, U., Saunders, R.
Archives of gynecology and obstetrics. 2023
Abstract
PURPOSE One of the most challenging tasks in laparoscopic gynecological surgeries is suturing. Knotless barbed sutures are intended to enable faster suturing and hemostasis. We carried out a meta-analysis to compare the efficacy and safety of V-Loc(™) barbed sutures (VBS) with conventional sutures (CS) in gynecological surgeries. METHODS We systematically searched PubMed and EMBASE for studies published between 2010 and September 2021 comparing VBS to CS for OB/GYN procedures. All comparative studies were included. Primary analysis and subgroup analyses for the different surgery and suturing types were performed. Primary outcomes were operation time and suture time; secondary outcomes included post-operative complications, surgical site infections, estimated blood loss, length of stay, granulation tissue formation, and surgical difficulty. Results were calculated as weighted mean difference (WMD) or risk ratio (RR) and 95% confidence intervals (CI) with a random effects model, and a sensitivity analysis for study quality, study size, and outlier results was performed. PROSPERO registration: CRD42022363187. RESULTS In total, 25 studies involving 4452 women undergoing hysterectomy, myomectomy, or excision of endometrioma. VBS were associated with a reduction in operation time (WMD - 17.08 min; 95% CI - 21.57, - 12.59), suture time (WMD - 5.39 min; 95% CI - 7.06, - 3.71), surgical site infection (RR 0.26; 95% CI 0.09, 0.78), estimated blood loss (WMD - 44.91 ml; 95% CI - 66.01, - 23.81), granulation tissue formation (RR 0.48; 95% CI 0.25, 0.89), and surgical difficulty (WMD - 1.98 VAS score; 95% CI - 2.83, - 1.13). No difference between VBS and CS was found regarding total postoperative complications or length of stay. Many of the outcomes showed high heterogeneity, likely due to the inclusion of different surgery types and comparators. Most results were shown to be robust in the sensitivity analysis except for the reduction in granulation tissue formation. CONCLUSION This meta-analysis indicates that V-Loc(™) barbed sutures are safe and effective in gynecological surgeries as they reduce operation time, suture time, blood loss, infections, and surgical difficulty without increasing post-operative complications or length of stay compared to conventional sutures.

World journal of surgical oncology. 2023;21(1):230
Abstract
OBJECTIVE Systematic evaluation of the efficacy and safety of robotic-assisted laparoscopic myomectomy (RALM) versus laparoscopic myomectomy (LM). METHODS PubMed, Embase, The Cochrane Library, and Web of Science database were searched by computer to seek relevant literature in order to compare the efficacy and safety of RALM with that of LM from the establishment of the databases to January 2023, and Review Manager 5.4 software was utilized to perform a meta-analysis on the literature. RESULTS A total of 15 retrospective clinical controlled studies were included. There exists a total of 45,702 patients, among 11,618 patients in the RALM group and the remaining 34,084 patients in the LM group. Meta-analysis results revealed that RALM was associated with lesser intraoperative bleeding (MD = - 32.03, 95%CI - 57.24 to - 6.83, P = 0.01), lower incidence of blood transfusions (OR = 0.86, 95%CI 0.77 to 0.97, P = 0.01), shorter postoperative hospital stay (MD = - 0.11, 95%CI - 0.21 to - 0.01, P = 0.03), fewer transitions to open stomach (OR = 0.82, 95%CI 0.73 to 0.92, P = 0.0006), and lower incidence of postoperative complications (OR = 0.58, 95%CI 0.40 to 0.86, P = 0.006) than LM, whereas LM is more advantageous in terms of operative time (MD = 38.61, 95%CI 19.36 to 57.86, P < 0.0001). There was no statistical difference between the two surgical methods in terms of maximum myoma diameter (MD = 0.26, 95%CI - 0.17 to 0.70, P = 0.24). CONCLUSION In the aspects of intraoperative bleeding, lower incidence of blood transfusions, postoperative hospital stay, transit open stomach rate, and postoperative complications, RALM has a unique advantage than that of LM, while LM has advantages over RALM in terms of operative time.

Maternal and child health journal. 2023
Abstract
INTRODUCTION Literature supports numerous benefits of skin-to-skin contact for neonatal adaptation to extrauterine life and bonding/attachment, but few studies explore the effects of skin-to-skin contact on maternal outcomes. This review aims to map the evidence on skin-to-skin contact in the third stage of labor for postpartum hemorrhage prevention. METHODS Scoping review, which covered stages recommended by the Institute Joanna Briggs, including studies from the PubMed, EMBASE, CINAHL, LILACS, Web of Science, and Scopus databases, using the descriptors "Postpartum hemorrhage", "Labor stages, third", "Prevention" and "Kangaroo care/Skin-to-skin". RESULTS 100 publications on the subject found, 13 articles met the inclusion criteria, with 10,169 dyads were assessed in all studies. Publications from 2008 to 2021 were mostly written in English and designed as a randomized controlled trial. Skin-to-skin contact was effective and significant in: reducing the duration of the third stage of labor; placenta delivery; uterine contractility and physiological involution; absence of atony, decreasing blood loss with lower rates of erythrocyte and hemoglobin drop; reducing the need for synthetic oxytocin and/or ergometrine to control bleeding; and reducing changing pads per period and length of stay. DISCUSSION Skin-to-skin contact was considered an effective, low-cost, and safe strategy, with positive effects already established in the literature for infants and extremely favorable results in postpartum hemorrhage prevention cases, being highly recommended in assistance for the dyad.

Abstract
Placenta accreta spectrum (PAS) can cause complications like hysterectomy or death due to massive pelvic bleeding. We aim to evaluate the efficacy of two different arterial ligation techniques in controlling postpartum haemorrhage and minimizing bleeding complications. We searched six databases. 11 studies were finally included into our review and analysis. We graded their quality using the Cochrane tool for randomized trials and the NIH tool for retrospective studies. Our analysis showed that internal iliac artery ligation has no significant effect on bleeding control (MD = -248.60 [-1045.55, 548.35] P = 0.54), while uterine artery ligation significantly reduced the amount of blood loss and preserved the uterus (MD = -260.75, 95% CI [-333.64, -187.86], P < 0.00001). Uterine artery ligation also minimized the need for blood transfusion. Bleeding was best controlled by combining both uterine artery ligation with uterine tamponade (MD = 1694.06 [1675.34, 1712.78], P < 0.00001). This combination also showed a significant decrease in hysterectomy compared to the uterine artery ligation technique alone. Bilateral uterine artery ligation in women with placenta accreta spectrum can effectively reduce the amount of bleeding and the risk of complications. The best bleeding control tested is a combination of both, uterine artery ligation and cervical tamponade. These techniques may offer an easy and applicable way to preserve fertility in PAS patients. Larger randomized trials are needed to define the best technique.

Abstract
INTRODUCTION Placental transfusion strategies in preterm newborns have not been evaluated in low- and middle-income countries (LMICs). The objective of this systematic review was to compare placental transfusion strategies in preterm newborns in LMICs, including delayed cord clamping (DCC) for various time intervals, DCC until cord pulsations stop, umbilical cord milking, and immediate cord clamping (ICC). METHODS Medline, Embase, CINAHL, and CENTRAL were searched from inception. Observational studies and randomized controlled trials (RCTs) were included. Two authors independently extracted data for Bayesian random-effects network meta-analysis (NMA) if more than 3 interventions reported an outcome or a pairwise meta-analysis was utilized. RESULTS Among newborns <34 weeks of gestation, NMA of 9 RCTs could not rule out benefit or harm for survival from DCC 30-60 s compared to ICC: relative risk (RR) (95% credible interval) 0.96 (0.78-1.12), moderate certainty, or any included strategy compared to each other (low to very low certainty). Among late preterm newborns, DCC 120 s might be associated with improved survival: RR (95% confidence interval) 1.11 (1.01-1.22), very low certainty. We could not detect differences in the risk of intraventricular hemorrhage grade > II and bronchopulmonary dysplasia for any included intervention (low to very low certainty). DCC 60 s and 120 s might improve the hematocrit level among all preterm newborns (very low certainty), and DCC 45 s may decrease the risk of receipt of inotropes among newborns <34 weeks of gestation (low certainty). CONCLUSIONS In LMICs, DCC for 60 s and 120 s might improve hematocrit level in preterm newborns, and DCC for 45 s may decrease the risk of receipt of inotropes in newborns <34 weeks, with no conclusive effect on survival.

Techniques for managing an impacted fetal head at caesarean section: A systematic review
Gq Peak A, Barwise E, Walker KF
European journal of obstetrics, gynecology, and reproductive biology. 2022;281:12-22
Abstract
A complication arising at caesarean birth when the baby's head is deeply engaged in the pelvis and may be difficult to deliver, is known as an 'impacted fetal head'. This obstetric emergency occurs in 16% of second stage caesarean sections. Multiple techniques are described in the literature to manage the complication but there is no consensus regarding which technique results in the best maternal and neonatal outcomes. The objective of this review is to determine which technique for managing impacted fetal head at caesarean section has the best maternal and neonatal outcomes. A literature search of three electronic databases was conducted in November 2021. Studies directly comparing two methods for the management of impacted fetal head at caesarean section in the second stage were included. Systematic reviews, meta-analyses, case-control studies, and studies not fitting the search criteria were excluded. Data was extracted in Covidence and meta-analysis of the six most commonly reported outcomes was conducted using RevMan 5.4. In total, 16 studies (3344women) were included. 13 studies (2506women) compared the push method with reverse breech extraction. meta-analysis showed that risk of extension of the uterine incision, blood transfusion, bladder injury, postpartum haemorrhage, NICU admission and Apgar score <7 at 5 min were significantly higher with the push method compared with reverse breech extraction. Three studies (838women) compared the push method with Patwardhan's technique. meta-analysis of studies comparing the push method with Patwardhan's technique found no significant differences between the two groups in any of the six maternal or neonatal outcomes. Evidence derived from small, inadequately powered studies suggests reverse breech extraction is associated with better outcomes than the push method. The method which produces the best outcomes is still unknown as not all methods have been tested. Further high quality, adequately powered RCTs are warranted for definitive conclusions to be drawn and to ameliorate the paucity of evidence on how best to manage this complication.

Abstract
BACKGROUND Laparoscopic excision of endometrioma and subsequent hemostasis have detrimental effects on ovarian reserve. OBJECTIVES To evaluate which hemostatic approach after stripping cystectomy shows less damage on ovarian reserve. SEARCH STRATEGY EMBASE, MEDLINE, Scopus, Scielo.br, LILACS, Cochrane at Central, Clinicaltrials.gov, CINAHL, conference abstracts and international controlled trials registry were searched from inception until April 2022. SELECTION CRITERIA Randomized controlled trials (RCTs) of women undergoing laparoscopic endometrioma excision that compared at least two hemostatic approaches. DATA COLLECTION AND ANALYSIS Relevant data were extracted and tabulated. Network meta-analysis based on random effects model for mixed multiple treatment to rank hemostatic strategies using the surface under the cumulative ranking curve area (SUCRA) was performed. Quality assessment was performed using Cochrane criteria. Primary outcome was serum Antimullerian hormone (AMH) levels 3 months after surgery. MAIN RESULTS Ten studies, including 748 women, were selected. Suturing the ovary with barbed suture (SUCRA=82.80%) seem the most effective strategy to avoid AMH reduction. Similarly, for ultrasonographic antral follicular count, barbed (SUCRA=30.70%) and simple suture (SUCRA=30.70%) were ranked best choices. Ovarian suturing with simple suture demonstrated lower FSH levels (SUCRA=88.70%). CONCLUSIONS Suturing the ovary, with simple or barbed suture, seems the most effective approach to keep ovarian reserve higher.
