The value of routine hemoglobin level evaluation following elective cesarean section: Is it worthwhile?

OBJECTIVE: The aim of this study was to assess the usefulness of routine hemoglobin testing following elective and urgent cesarean section (CS) in patients without primary postpartum hemorrhage (PPH). METHODS: This retrospective cohort study included women who underwent vaginal delivery (VD), elective CS, and urgent CS at Carmel Medical Center from 2015 to 2020. Data were extracted from the obstetric database, excluding deliveries with PPH. Demographic and obstetric variables were recorded. Primary outcomes were the need for packed red blood cell transfusion. RESULTS: A total of 19 446 women were included, with five (0.3%) requiring a blood transfusion in the elective CS group, 27 (0.17%) in the VD group, and eight (0.4%) in the urgent CS group. Urgent CS was associated with a higher risk of blood transfusion, but there was no significant difference between elective CS and VD. Elective CS showed the lowest rates of post-delivery hemoglobin below 7 g/dL 1 (0.1%) compared to VD 16 (0.6%) and urgent CS 13 (0.7%). CONCLUSION: Routine postoperative hemoglobin testing following elective CS in asymptomatic patients without PPH appears unnecessary. This study supports reconsidering routine hemoglobin testing following elective CS, aligning with the goal of optimizing resource utilization while maintaining patient quality.

Impact of pre-delivery medication treatment on delivery outcome in patients with primary immune thrombocytopenia: a cohort study.

BACKGROUND: Clinical research data showed a series of adverse events in the delivery period of primary immune thrombocytopenia (ITP) patients, including high cesarean section rate. Consensus report proposed that for patients with platelet count below 50 × 109/L, prednisone or intravenous immunoglobulins (IVIg) can be given to raise the platelet count in third trimester in preparation for labor. OBJECTIVES: To evaluate the effect of low-dose prednisone or IVIg therapy on delivery outcomes in patients with ITP. STUDY DESIGN: This was a cohort study that included pregnant women with ITP from January 2017 to December 2022. Patients with platelet counts of (20-50) ×109/L at the time of delivery (≥34 weeks) and who had not received any medication before were enrolled in the study. Patients were divided into the pre-delivery medication group (oral prednisone or IVIg) and untreated group according to their preferences. The differences in vaginal delivery rate, postpartum bleeding rate, and platelet transfusion volume between the two groups were compared using t-test, Wilcoxon rank-sum test, and χ2 test. Logistic regression analysis was used to identify the factors affecting vaginal delivery rate and postpartum bleeding rate, and multiple linear regression analysis was used to identify the factors affecting platelet transfusion volume. RESULTS: During the study period, a total of 96 patients with ITP were enrolled, including 70 in the pre-delivery medication group and 26 in the untreated group. The platelet count of pre-delivery medication group was 54.8 ± 34.5 × 109/L, which was significantly higher than that of untreated group 34.4 ± 9.0 × 109/L (p = .004). The vaginal delivery rate of the medication group was higher than the untreated group [60.0% (42/70) vs. 30.8% (8/26), χ2 = 6.49, p = .013]. After adjusting for the proportion of multiparous women and gestational weeks, the results showed that medication therapy during the peripartum period was associated with vaginal delivery (OR = 4.937, 95% CI: 1.511-16.136, p = .008). The postpartum bleeding rates were 22.9% (16/70) and 26.9% (7/26) in the medication group and untreated group, respectively, with no significant difference between the two groups (χ2 = 0.17, p = .789), while the platelet transfusion volume was lower in the medication group than untreated group [(1.1 ± 1.0) vs. (1.6 ± 0.8) U]. CONCLUSION: Pre-delivery medication therapy can increase vaginal delivery rate, reduce platelet transfusion volume, but does not decrease the incidence of postpartum hemorrhage.

What is the context?The high cesarean section rate has always been a prominent pregnancy issue in ITP patients. The data shows that the reason for cesarean section in most ITP patients may be related to early induced labor due to thrombocytopenia or patients' concerns of bleeding events during delivery. The study of treatment during the perinatal period is expected to further increase platelet count and prepare for safer delivery.What is new?To date, no study has focused on pre-delivery treatment for pregnant ITP patients. In this study, patients with a platelet count<50 × 109/L after 34 weeks can experience a significant increase in platelet count after receiving immunoglobulin or prednisone therapy. The results of this study preliminarily demonstrate IVIg or prednisone is a promising pre-delivery treatment for pregnant ITP patients in preparation for labor. The pre-delivery medication therapy can improve the rate of successful vaginal delivery and reduce the consumption of blood products.What is the impact?This study provides further evidence that the target threshold for platelets should be raised in late third trimester, with a platelet count above 50 × 109/L as the standard for delivery, in order to further reduce the cesarean section rate and blood product infusion in ITP patients.

Postpartum obstetric complications: a guide for radiologists.

The puerperium refers to the 6-8 weeks following delivery, and is a dynamic period in which maternal anatomy and physiology are restored to their prepregnant state. Postpartum complications can be divided into non-obstetric and obstetric. The latter are the topic of this article and can be further classified as infectious, thrombotic, hemorrhagic or cesarean-related. Transvaginal US is often the initial modality in the evaluation of puerperal disorders. CT is probably the most valuable imaging technique when life-threatening conditions are suspected. Pelvic MRI is being increasingly used in cases of inconclusive findings or if further characterization is needed, especially in the setting of postsurgical complications or placental disorders. Diagnostic and interventional radiologists play a pivotal role in the evaluation and management of a variety of puerperal complications. Many of these conditions pose a diagnostic challenge, as imaging findings often overlap with normal postpartum changes, so keeping in mind the patient's clinical information is key.

Impact of planned delivery mode on neonatal outcomes and costs in twin pregnancies in Kenya.

Background: Twin pregnancies are associated with higher risks of adverse neonatal outcomes compared to singleton pregnancies. The choice of delivery mode, when twin A presents cephalic, remains a subject of debate. In low- and middle-income countries, where healthcare resources are limited, the decision on the mode of delivery is even more critical. Objective: To evaluate the neonatal outcomes and the hospital costs of planned vaginal delivery compared to cesarean section (CS) in twin pregnancies with twin A presenting cephalic at Tenwek Hospital, Kenya. Study Design: This retrospective cohort study analyzed data from all twin deliveries at Tenwek Hospital, Kenya from, April 1, 2017, to March 30, 2023. Maternal data, mode of delivery, and neonatal data were collected from delivery logs, electronic health records, and neonatal records. Neonatal outcomes were a composite of either Appearance, Pulse, Grimace, Activity, and Respiration score less than seven at 5 minutes, neonatal intensive care unit admission, resuscitation, birth trauma, or neonatal complications, including death before discharge from the hospital. A logistic regression model was created to assess the impact of the planned mode of delivery on neonatal outcomes, controlling for antenatal care clinic visits, noncephalic presentation of twin B, and birth weight category. Results: The study included 177 twin deliveries: 129 (72.9%) were planned as vaginal deliveries and 48 (27.1%) were planned for CS. Among the planned vaginal deliveries, 66 (51.2%) experienced adverse outcomes, compared to 14 (29.2%) in the CS group (P=.009). Logistic regression showed that the odds of adverse outcomes were 0.35 times lower in the CS group compared to the planned vaginal delivery group (95% CI: 0.15-0.83; P=.017). The average total hospital costs for planned vaginal delivery were 104,608 Kenya Shillings (standard deviation 111,761) compared to 100,708 Kenya Shillings (standard deviation 75,468) for CS (P=.82). Conclusion: Planned cesarean deliveries in twin pregnancies with twin A presenting cephalic at Tenwek Hospital were associated with fewer adverse neonatal outcomes compared to planned vaginal deliveries. There was no significant difference in hospital costs. These findings raise the question of the safest mode of delivery for patients in a resource-constrained setting.

Effect of an Intrapartum Pelvic Dilator Device on Levator Ani Muscle Avulsion During Primiparous Vaginal Delivery: A Pilot Randomized Controlled Trial.

INTRODUCTION AND HYPOTHESIS: The objective was to evaluate the safety and effectiveness of an intrapartum electromechanical pelvic floor dilator designed to reduce the risk of levator ani muscle (LAM) avulsion during vaginal delivery. METHODS: A multicenter, randomized controlled trial enrolled nulliparous participants planning vaginal delivery. During the first stage of labor, participants were randomized to receive the intravaginal device or standard-of-care labor management. The primary effectiveness endpoint was the presence of full LAM avulsion on transperineal pelvic-floor ultrasound at 3 months. Three urogynecologists performed blinded interpretation of ultrasound images. The primary safety endpoint was adverse events (AEs) through 3 months. RESULTS: A total of 214 women were randomized to Device (n = 113) or Control (n = 101) arms. Of 113 Device assignees, 82 had a device placed, of whom 68 delivered vaginally. Of 101 Control participants, 85 delivered vaginally. At 3 months, 110 participants, 46 Device subjects who received full device treatment, and 64 Controls underwent ultrasound for the per-protocol analysis. No full LAM avulsions (0.0%) occurred in the Device group versus 7 out of 64 (10.9%) in the Control group (p = 0.040; two-tailed Fisher's test). A single maternal serious AE (laceration) was device related; no neonate serious AEs were device related. CONCLUSIONS: The pelvic floor dilator device significantly reduced the incidence of complete LAM avulsion in nulliparous individuals undergoing first vaginal childbirth. The dilator demonstrated an acceptable safety profile and was well received by recipients. Use of the intrapartum electromechanical pelvic floor dilator in laboring nulliparous individuals may reduce the rate of LAM avulsion, an injury associated with serious sequelae including pelvic organ prolapse.

Tranexamic Acid in Preventing Postpartum Blood Loss in Vaginal Delivery- a Double Blinded, Randomized Controlled Trial.

OBJECTIVE: To assess the effect of prophylactic tranexamic acid (1 g) in reducing postpartum blood loss and the incidence of PPH after vaginal delivery, in addition to active management of third stage of labour. METHODS: In this randomized controlled trial, 650 women with singleton pregnancies of ≥ 34 weeks gestation who were undergoing vaginal delivery were included. Eligible women were randomly assigned to receive either 1 g of tranexamic acid or placebo intravenously in addition to active management of third stage of labour. Calibrated blood collection bags were used to measure postpartum blood loss during the third and fourth stage of labour. RESULTS: Out of 886 women who were approached for the study, 650 who met the inclusion criteria were enrolled, and 320 in group A and 321 in group B were analysed. Maternal characteristics were similar in both groups. Mean blood loss did not differ significantly among the intervention and placebo groups (378.5±261.2 ml vs. 383±258.9 ml; p = 0.93). The incidence of primary postpartum hemorrhage was comparable in both groups (Group A: 15.9%, Group B: 15.3%, p = 0.814). The median (interquartile) quantitative fall in haemoglobin within 12-24 hours following delivery in group A was 0.60 g% (0.40-0.90) and group B was 0.60 g% (0.40-0.80) which were comparable in both groups (p=0.95). The most common adverse effect reported was dizziness and there were no thromboembolic events at three months follow-up in both groups. CONCLUSION: The use of tranexamic acid as a prophylactic measure along with active management of third stage of labour does not provide additional benefit in reducing the postpartum blood loss as well as incidence of PPH after vaginal delivery.

The mode of delivery after operative fixation of pelvic ring fractures-a retrospective observational study.

PURPOSE: The purpose of this study is to investigate whether retained hardware after surgical treatment for a pelvic fracture prior to pregnancy affects the choice of delivery method. The study aims to provide insights into the rates of vaginal delivery and caesarean sections, understanding whether the mode of delivery was influenced by patient preference or the recommendations of obstetricians or surgeons, and examining the rate of complications during delivery and postpartum. METHODS: All women of childbearing age who underwent surgical fixation for a pelvic ring fracture between 1994 and 2021 were identified. A questionnaire was sent about their possible pregnancies and deliveries. Of the included patients, surgical data were collected and the fracture patterns were retrospectively classified. Follow-up was a minimum of 36 months. RESULTS: A total of 168 women with a pelvic fracture were identified, of whom 13 had a pregnancy after surgical stabilization. Eleven women had combined anterior and posterior fracture patterns and two had isolated sacral fractures. Four women underwent combined anterior and posterior fixation, the others either anterior or posterior fixation. Seven women had a total of 11 vaginal deliveries, and 6 women had 6 caesarean sections. The decision for vaginal delivery was often the wish of the mother (n = 4, 57%) while the decision to opt for caesarean section was made by the surgeon or obstetrician (n = 5, 83%). One woman in the vaginal delivery group suffered a postpartum complication possibly related to her retained pelvic hardware. CONCLUSION: Women with retained hardware after pelvic ring fixation can have successful vaginal deliveries. Complications during labor or postpartum are rare. The rate of primary caesarean sections is high (46%) and is probably influenced by physician bias. Future research should focus on tools that can predict labor outcomes in this specific population, and larger multicenter studies are needed. LEVEL OF EVIDENCE: Level III.

Vaginal Delivery in a Tracheostomised Woman: A Rare Case Scenario.

Spontaneous vaginal delivery in a tracheostomised woman is rare and literature concerning the same is also very limited, hence this might help in considering vaginal delivery at term as an option in such patients when there are no medical or obstetrical contraindications for the same. We present a case of a 24 years female patient hailing from Tamil Nadu in South India, who was tracheostomised secondary to subglottic stenosis, presented to Otorhinolaryngology department at thirty-eight weeks of gestation to know the possibility of a vaginal delivery at term. Since the patient had an uneventful obstetrical history and no medical or obstetrical contraindications for a vaginal delivery, patient was advised breathing exercises including Valsalva manoeuvre and kept under close follow up. Patient went to labor at term at thirty-nine weeks and five days of gestation, and with the help of a panel of senior doctors underwent spontaneous vaginal delivery with no complications. Vaginal delivery can be attempted in tracheostomised women, in the absence of any medical or obstetrical contra indications, if the patient is motivated and we have a panel of expert doctors from all concerned departments.

Emergency Surgery for Adnexal Torsion in Late Preterm Pregnancy Causing Term Vaginal Delivery: A Case Report and Literature Review.

Adnexal cyst torsion in late preterm pregnancies is rare, but it frequently causes secondary uterine contractions. Thus, deciding on performing a simultaneous cesarean section due to the potential for early postoperative labor onset is crucial despite no obstetric indications. Here, we report a case of adnexal torsion at 34 weeks of gestation treated with emergency surgery, followed by a full-term vaginal delivery, along with a literature review. A 31-year-old primigravida at 34 weeks and four days of gestation presented to the emergency department with right lower abdominal pain. An emergency laparotomy was performed to achieve term delivery, suspecting right ovarian cyst torsion without signs of fetal distress. General anesthesia with sevoflurane was selected over spinal anesthesia, considering the incision height. The patient was placed in the left lateral decubitus position on the operating table to ensure proper visualization and maintain uterine circulation. A 4-cm transverse skin incision was made under ultrasound guidance, revealing the twisted right paratubal cyst immediately beneath. The cyst was excised, and the torsion was relieved. The postoperative course was uneventful, and spontaneous labor occurred at 39 weeks and six days of gestation, resulting in a vaginal delivery at 40 weeks. This case demonstrates that even late preterm adnexal torsion can be managed safely with appropriate surgical techniques, allowing for a subsequent term vaginal delivery.

ENhancinG vAGinal dElivery in Greece through educational and behavioral interventions among maternity care providers regarding labor management: the ENGAGE stepped-wedge randomized prospective trial protocol.

BACKGROUND: There is an emerging need to systematically investigate the causes for the increased cesarean section rates in Greece and undertake interventions so as to substantially reduce its rates. To this end, the ability of the participating Greek obstetricians to follow evidence-based guidelines and respond to other educational and behavioral interventions while managing labor will be explored, along with barriers and enablers. Herein discussed is the protocol of a stepped-wedge designed intervention trial in Greek maternity units with the aforementioned goals in mind, named ENGAGE (ENhancinG vAGinal dElivery in Greece). METHODS: Twenty-two selected maternity units in Greece will participate in a multicenter stepped-wedge randomized prospective trial involving 20,000 to 25,000 births, with two of them entering the intervention period of the study each month (stepped randomization). The maternity care units entering the study will apply the suggested interventions for a period of 8-18 months depending on the time they enter the intervention stage of the study. There will also be an initial phase of the study lasting from 8 to 18 months including observation and recording of the routine practice (cesarean section, vaginal birth, and maternal and perinatal morbidity and mortality) in the participating units. The second phase, the intervention period, will include such interventions as the application of the HSOG (the Hellenic Society of Obstetrics and Gynecology) Guidelines on labor management, training on the correct interpretation of cardiotocography, and dealing with emergencies in vaginal deliveries, while the steering committee members will be available to discuss and implement organizational and behavioral changes, answer questions, clarify relevant issues, and provide practical instructions to the participating healthcare professionals during regular visits or video conferences. Furthermore, during the study, the results will be available for the participating units in order for them to monitor their own performance while also receiving feedback regarding their rates. Τhe final 2-month phase of the study will be devoted to completing follow-up questionnaires with data concerning maternal and neonatal morbidities that occurred after the completion of the intervention period. The total duration of the study is estimated at 28 months. The primary outcome assessed will be the cesarean section rate change and the secondary outcomes will be maternal and neonatal morbidity and mortality. DISCUSSION: The study is expected to yield new information on the effects, advantages, possibilities, and challenges of consistent clinical engagement and implementation of behavioral, educational, and organizational interventions described in detail in the protocol on cesarean section practice in Greece. The results may lead to new insights into means of improving the quality of maternal and neonatal care, particularly since this represents a shared effort to reduce the high cesarean section rates in Greece and, moreover, points the way to their reduction in other countries. TRIAL REGISTRATION: NCT04504500 (ClinicalTrials.gov). The trial was prospectively registered.

How the Mode of Delivery Is Influenced by Patient's Opinions and Risk-Informed Consent in Women with a History of Caesarean Section? Is Vaginal Delivery a Real Option after Caesarean Section?

Background/Objectives: In recent years, there has been a noticeable increase in the rates of caesarean section (CS), being one of the most commonly performed surgical procedures. For the following pregnancy, the previous CS represents the backbone of the risks and complications, such as uterine scar formation, uterine rupture, massive bleeding, and serious negative outcomes for both the mother and child. Our study followed patients with a history of CS from the birth planning prenatal check-up to delivery. Methods: We reviewed the records of 125 pregnant women with previous CS who presented in the third trimester for a prenatal check-up and completed our questionnaire from March 2021 to April 2022 in the Clinic of Obstetrics and Gynecology, Diakoneo Diak Klinikum Schwäbisch Hall, Germany. Results: Before the prenatal check-up, 74 patients (59.2%) preferred vaginal delivery (VD), while 51 (40.8%) preferred CS. After discussing birth planning with the obstetrician, 72 women (57.6%) decided upon VD, while 53 (42.4%) preferred CS. Ultimately, 78 (62.4%) of women gave birth through CS (either planned or by medical necessity) and 47 (37.6%) gave birth vaginally (either natural or per vacuum extraction). Conclusions: VD for patients with CS in their medical history is a real option. The patient must be well informed about the risks and benefits of the medical situation and should be empowered and supported on their chosen mode of delivery, which should be respected.

A qualitative and quantitative cross-sectional study on the past, present, and future of vaginal delivery: Turkey.

OBJECTIVE: The current study focused on predicting future trends in obstetrics by examining obstetricians' approaches to specific challenging vaginal delivery that require special experience, such as breech presentation, macrosomic fetus, twin pregnancy, and vacuum use, compared with their residency training experience. METHODS: The cross-sectional study was conducted in two phases. The first phase was qualitative and the second phase was quantitative. The "interview" and "survey" techniques served as data collection tools. In total, 20 obstetricians participated in the interviews, and 400 obstetricians took part in the survey. Data from the interviews were analyzed using the Maxqda 2020 qualitative data analysis program, and survey data were analyzed using SPSS version 25.0. RESULTS: Over the past 2 decades, there has been a gradual shift from vaginal deliveries to cesarean deliveries in cases involving breech presentation, macrosomic fetus, twin pregnancy, and vacuum use. While medicolegal concerns are undeniable, the prevalent belief among obstetricians that cesarean delivery is safer than vaginal delivery significantly influences this trend. Comparatively, young obstetricians often complete their residency training without acquiring sufficient knowledge and skills in vaginal delivery. CONCLUSION: Young obstetricians currently lack adequate experience in managing vaginal deliveries for breech presentation, macrosomic fetus, twin pregnancy, and vacuum use. This experience is at risk of disappearing entirely within the next decade as senior obstetricians retire. Policymakers should take this into consideration when shaping future healthcare policies.

Outcomes in term breech birth according to intended mode of delivery-A Swedish prospective single-center experience of a dedicated breech birth team.

INTRODUCTION: The appropriate mode of delivery for breech babies is a topic of ongoing debate. After the publication of the Term Breech Trial in 2000, the proportion of breech babies delivered vaginally in Sweden rapidly dropped to 7% from 26%. In 2015, international guidelines changed to once again recommend offering vaginal breech deliveries in select cases. In 2017, a Swedish hospital established a dedicated Breech Team to provide safe vaginal breech deliveries according to the new guidelines. The aim of this study is to compare neonatal morbidity in the group planned for cesarean breech delivery with the group planned for vaginal breech delivery treated in accordance with the new guidelines. The study adds to the literature by providing insights into the consequences of reintroducing vaginal breech births in a high-resource health-care setting. MATERIAL AND METHODS: A prospective observational study was conducted at Södersjukhuset's maternity ward with 1067 women who gave birth to a single breech fetus at term. Outcomes were compared between the planned vaginal and planned cesarean delivery groups using intention-to-treat analysis and multivariate analysis to control for confounders. RESULTS: Out of the 1067 women, 78.9% were planned for cesarean delivery and 21.1% were planned for vaginal delivery. The planned vaginal group had a significantly greater risk for neonatal morbidity compared to the planned cesarean group (3.1% vs. 0.7%; OR 4.44, 95% CI 1.48-13.34). The risk difference remained significant after controlling for confounders. CONCLUSIONS: Planned vaginal breech delivery was associated with an increased risk of neonatal mortality and short-term morbidity compared to planned cesarean breech delivery in accordance with the new guidelines. The potential risks and benefits of planned vaginal breech delivery should be carefully weighed against those of planned cesarean delivery.

Effects of tranexamic acid preconditioning on the incidence of postpartum haemorrhage in vaginal deliveries with identified risk factors in China: a prospective, randomized, open-label, blinded endpoint trial.

OBJECTIVE: This study aimed to evaluate the effects of tranexamic acid (TXA) in preventing postpartum haemorrhage (PPH) among women with identified risk factors for PPH undergoing vaginal delivery in China. METHODS: This prospective, randomized, open-label, blinded endpoint (PROBE) trial enrolled 2258 women with one or more risk factors for PPH who underwent vaginal delivery. Participants were randomly assigned in a 1:1 ratio to receive an intravascular infusion of 1 g TXA or a placebo immediately after the delivery of the infant. The primary outcome assessed was the incidence of PPH, defined as blood loss ≥500 mL within 24 h after delivery, while severe PPH was considered as a secondary outcome and defined by total blood loss ≥1000 mL within 24 h. RESULTS: 2245 individuals (99.4%) could be followed up to their primary outcome. PPH occurred in 186 of 1128 women in the TXA group and in 215 of 1117 women in the placebo group (16.5% vs. 19.2%; RR, 0.86; 95% CI, 0.72 to 1.02; p = 0.088). Regarding secondary outcomes related to efficacy, women in the TXA group had a significant lower rate of severe PPH than those in the placebo group (2.7% vs. 5.6%; RR, 0.49; 95% CI, 0.32 to 0.74; p = 0.001; adjusted p = 0.002). Similarly, there was a significant reduction in the use of additional uterotonic agents (7.8% vs. 15.6%; RR, 0.50; 95% CI, 0.39 to 0.63; p < 0.001; adjusted p = 0.001). No occurrence of thromboembolic events and maternal deaths were reported in both groups within 30 days after delivery. CONCLUSIONS: In total population with risk factors for PPH, the administration of TXA following vaginal delivery did not result in a statistically significant reduction in the incidence of PPH compared to placebo; however, it was associated with a significantly lower incidence of severe PPH.

Prophylactic administration of TXA did not yield a statistically significant reduction in the incidence of PPH among women with risk factors in vaginal deliveries.Prophylactic use of TXA may help to reduce the incidence of severe PPH.

Incidence of obstetric anal sphincter injuries according to the type of forceps used in the Mexican population.

OBJECTIVE: This study describes the frequency of obstetric anal sphincter injuries (OASIS) in patients after instrumental delivery according to the type of forceps used. METHODS: A retrospective comparative cohort study was conducted on patients who underwent instrumental delivery from January 2017 to April 2022. The primary outcome was the presence of OASIS following delivery. Patients were categorized into Cohort A if only rotation forceps were used, Cohort B for only traction forceps, and Cohort C if both types were used sequentially. Statistical analysis was performed with SPSS (IBM, New York, NY) with χ2, Fisher's exact, and analysis of variance testing. A P-value <0.05 was considered significant. RESULTS: OASIS occurred in 45 of 328 instrumental deliveries. OASIS after rotation forceps occurred in 12.9% (n = 8) of cases, after traction forceps in 13.2% (n = 34), and after sequential use of rotation and traction forceps in 37.5% (n = 3) of cases (p = 0.141). An odds ratio (OR) of 0.91 (95% confidence interval [CI] 0.40-2.08) for OASIS was obtained with the use of rotation forceps, 0.81 (95% CI 0.38-1.70) for traction forceps, and 3.97 (95% CI 0.91-17.2) for the sequential use of rotation and traction forceps. CONCLUSION: There were no significant differences in the presence of OASIS comparing traction and rotation forceps. A non-significant trend of higher OASIS following the sequential use of traction and rotation forceps was observed.

Temporal trends and regional variations in operative vaginal deliveries in Japan: A national representative cohort study.

AIM: To analyze temporal trends and regional variations in operative vaginal delivery (OVD) in Japan. METHODS: Using the National Database of Health Insurance Claims and Specific Health Checkups of Japan from 2014 to 2021, we identified the numbers of vacuum and forceps deliveries. We analyzed annual totals and proportions of OVDs and calculated the mean age of women undergoing these deliveries. We also predicted trends in OVD for the next 20 years and compared geographical differences in the proportions of forceps deliveries among OVDs. RESULTS: During the observation period, out of 7 368 814 total births, 8.4% were through OVD, including 7.6% by vacuum and 0.8% by forceps. Both delivery methods showed an increasing trend from 2014 to 2021: vacuum deliveries rose from 7.0% to 8.7%, and forceps deliveries increased from 0.6% to 1.0%. Notably, the proportion of forceps deliveries in OVD increased from 8.1% to 10.5%. The mean age was higher for forceps deliveries than vacuum deliveries. According to our predictions, vacuum deliveries may continue to increase, but forceps deliveries may stabilize. The proportion of forceps deliveries among OVDs ranged from 0% to 38% across Japanese prefectures. CONCLUSIONS: This study shows an increase in the use of OVD in Japan from 2014 to 2021. There are large regional differences in the choice between vacuum and forceps deliveries. These findings can help us understand the practice of OVD in Japan.

Effect of anesthesia on the success rate of external cephalic version: GRADE- assessed systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: External cephalic version (ECV) is a medical procedure in which an extracorporeal manipulation is performed to render the breech presentation (BP) fetus in the cephalic position. The use of anesthesia to facilitate repositioning has been evaluated in various randomized clinical trials (RCTs), but its potential effectiveness remains controversial. METHODS: A systematic literature search was carried out in 8 electronic databases. In the meta-analysis, a random effects model was used to calculate the pooled relative risk (RR) and its 95% confidence interval (CI), and the pooled standardized mean difference (SMD) and its 95% CI, in order to systematically assess the effect of anesthesia on the success rates of ECV, vaginal delivery, cesarean delivery as well as other outcomes. Relevant subgroup analyses, publication bias test and sensitivity analyses were also conducted. RESULTS: This review included 17 RCTs. Women who received anesthesia had a significantly higher incidence of successful ECV (RR: 1.37, 95% CIs: 1.19-1.58) and vaginal delivery (RR: 1.23, 95% CIs: 1.03-1.47), and a significantly lower incidence of cesarean delivery (RR: 0.69, 95% CIs: 0.53-0.91), compared with those who did not. CONCLUSION: The administration of anesthesia not only significantly reduces maternal pain but also significantly increases the success rate of ECV in women with malpresentation at term, leading to a significant rise in the incidence of vaginal delivery. However, it may increase the incidence of maternal hypotension. SYSTEMATIC REVIEW REGISTRATION: The protocol was prospectively registered with PROSPERO, registration CRD42022381552.

A Rare Case of Broad Ligament Hematoma Following Vaginal Delivery.

This case report explores a rare complication of broad ligament hematoma post-vaginal delivery, emphasizing the importance of prompt intervention in cases of postpartum hemorrhage with atypical presentations. A 22-year-old primigravida, at 39 weeks with hypothyroidism, presented with intermittent abdominal pain and normal fetal movements. After a normal vaginal delivery with a right mediolateral episiotomy, she developed intense perineal pain and hypotension due to a broad ligament hematoma. The surgical intervention included the evacuation of the hematoma, laparotomy, and internal iliac artery ligation. The postoperative care involved treatment for a methicillin-resistant Staphylococcus aureus (MRSA) infection, and the patient received blood transfusions. The follow-up showed complete wound healing and an uneventful postnatal period, with the patient resuming normal activities after three weeks. Comparison with similar cases in the literature highlighted various etiologies and clinical presentations of broad ligament hematoma, ranging from broad ligament pregnancy to uterine perforation. Timely surgical exploration, hematoma evacuation, and arterial ligation were essential in preventing adverse maternal outcomes, underscoring the importance of multidisciplinary collaboration and vigilant postoperative monitoring. The report emphasizes the need for a high index of suspicion and prompt intervention to ensure optimal recovery and minimize complications in cases of broad ligament hematoma following vaginal delivery.

Mode of delivery predicts postpartum maternal leukocyte telomere length.

BACKGROUND: Recent studies have suggested that pregnancy accelerates biologic aging, yet little is known about how biomarkers of aging are affected by events during the peripartum period. Given that immune shifts are known to occur following surgery, we explored the relation between mode of delivery and postpartum maternal leukocyte telomere length (LTL), a marker of biologic aging. STUDY DESIGN: Postpartum maternal blood samples were obtained from a prospective cohort of term, singleton livebirths without hypertensive disorders or peripartum infections between 2012 and 2018. The primary outcome was postpartum LTLs from one blood sample drawn between postpartum week 1 and up to 6 months postpartum, measured from thawed frozen peripheral blood mononuclear cells using quantitative PCR in basepairs (bp). Multivariable linear regression models compared LTLs between vaginal versus cesarean births, adjusting for age, body mass index, and nulliparity as potential confounders. Analyses were conducted in two mutually exclusive groups: those with LTL measured postpartum week 1 and those measured up to 6 months postpartum. Secondarily, we compared multiomics by mode of delivery using machine-learning methods to evaluate whether other biologic changes occurred following cesarean. These included transcriptomics, metabolomics, microbiomics, immunomics, and proteomics (serum and plasma). RESULTS: Of 67 included people, 50 (74.6 %) had vaginal and 17 (25.4 %) had cesarean births. LTLs were significantly shorter after cesarean in postpartum week 1 (5755.2 bp cesarean versus 6267.8 bp vaginal, p = 0.01) as well as in the later draws (5586.6 versus 5945.6 bp, p = 0.04). After adjusting for confounders, these differences persisted in both week 1 (adjusted beta -496.1, 95 % confidence interval [CI] -891.1, -101.1, p = 0.01) and beyond (adjusted beta -396.8; 95 % CI -727.2, -66.4. p = 0.02). Among the 15 participants who also had complete postpartum multiomics data available, there were predictive signatures of vaginal versus cesarean births in transcriptomics (cell-free [cf]RNA), metabolomics, microbiomics, and proteomics that did not persist after false discovery correction. CONCLUSION: Maternal LTLs in postpartum week 1 were nearly 500 bp shorter following cesarean. This difference persisted several weeks postpartum, even though other markers of inflammation had normalized. Mode of delivery should be considered in any analyses of postpartum LTLs and further investigation into this phenomenon is warranted.
