Strategies for optimising early detection and obstetric first response management of postpartum haemorrhage at caesarean birth: a modified Delphi-based international expert consensus.

OBJECTIVE: There are no globally agreed on strategies on early detection and first response management of postpartum haemorrhage (PPH) during and after caesarean birth. Our study aimed to develop an international expert's consensus on evidence-based approaches for early detection and obstetric first response management of PPH intraoperatively and postoperatively in caesarean birth. DESIGN: Systematic review and three-stage modified Delphi expert consensus. SETTING: International. POPULATION: Panel of 22 global experts in PPH with diverse backgrounds, and gender, professional and geographic balance. OUTCOME MEASURES: Agreement or disagreement on strategies for early detection and first response management of PPH at caesarean birth. RESULTS: Experts agreed that the same PPH definition should apply to both vaginal and caesarean birth. For the intraoperative phase, the experts agreed that early detection should be accomplished via quantitative blood loss measurement, complemented by monitoring the woman's haemodynamic status; and that first response should be triggered once the woman loses at least 500 mL of blood with continued bleeding or when she exhibits clinical signs of haemodynamic instability, whichever occurs first. For the first response, experts agreed on immediate administration of uterotonics and tranexamic acid, examination to determine aetiology and rapid initiation of cause-specific responses. In the postoperative phase, the experts agreed that caesarean birth-related PPH should be detected primarily via frequently monitoring the woman's haemodynamic status and clinical signs and symptoms of internal bleeding, supplemented by cumulative blood loss assessment performed quantitatively or by visual estimation. Postoperative first response was determined to require an individualised approach. CONCLUSION: These agreed on proposed approaches could help improve the detection of PPH in the intraoperative and postoperative phases of caesarean birth and the first response management of intraoperative PPH. Determining how best to implement these strategies is a critical next step.

Emergency cesarean section of a patient with refractory status epilepticus: A case report of challenges during anesthesia.

INTRODUCTION: Maternal epilepsy is a critical condition that can significantly affect mothers and fetuses. Notably, the admission of a laboring mother with uncontrolled refractory status epilepticus (RSE) to the operating room presents a challenging scenario for anesthesiologists. THE MAIN SYMPTOMS OF THE PATIENT AND THE IMPORTANT CLINICAL FINDINGS: A 30-year-old primigravida was transferred to the operating room for an emergency cesarean section. Cesarean section was performed after a provisional diagnosis of preeclampsia was made. THE MAIN DIAGNOSES, THERAPEUTIC INTERVENTIONS, AND OUTCOMES: Cesarean section was performed under general anesthesia. During the postoperative period, the patient exhibited no seizure activity in the brain; however, she experienced mild cognitive dysfunction for up to 6 months postdelivery. The neonate were discharged without any complications. CONCLUSION: Inducing anesthesia in pregnant women with ongoing seizure activity are challenging; however, anesthesiologists provide judgment based on the balance between the safety of the mother and fetus and the balance between patient monitoring and the progression of anesthesia. This challenge can be addressed through multidisciplinary collaboration.

Fungal-bacteria interactions provide shelter for bacteria in Caesarean section scar diverticulum.

Caesarean section scar diverticulum (CSD) is a significant cause of infertility among women who have previously had a Caesarean section, primarily due to persistent inflammatory exudation associated with this condition. Even though abnormal bacterial composition is identified as a critical factor leading to this chronic inflammation, clinical data suggest that a long-term cure is often unattainable with antibiotic treatment alone. In our study, we employed metagenomic analysis and mass spectrometry techniques to investigate the fungal composition in CSD and its interaction with bacteria. We discovered that local fungal abnormalities in CSD can disrupt the stability of the bacterial population and the entire microbial community by altering bacterial abundance via specific metabolites. For instance, Lachnellula suecica reduces the abundance of several Lactobacillus spp., such as Lactobacillus jensenii, by diminishing the production of metabolites like Goyaglycoside A and Janthitrem E. Concurrently, Clavispora lusitaniae and Ophiocordyceps australis can synergistically impact the abundance of Lactobacillus spp. by modulating metabolite abundance. Our findings underscore that abnormal fungal composition and activity are key drivers of local bacterial dysbiosis in CSD.

Surgical treatment and reproductive outcomes in caesarean scar pregnancy at a single center.

BACKGROUND: To investigate factors associated with different reproductive outcomes in patients with Caesarean scar pregnancies (CSPs). METHODS: Between May 2017 and July 2022, 549 patients underwent ultrasound-guided uterine aspiration and laparoscopic scar repair at the Gynaecology Department of Hubei Maternal and Child Health Hospital. Ultrasound-guided uterine aspiration was performed in patients with type I and II CSPs, and laparoscopic scar repair was performed in patients with type III CSP. The reproductive outcomes of 100 patients with fertility needs were followed up and compared between the groups. RESULTS: Of 100 patients, 43% had live births (43/100), 19% had abortions (19/100), 38% had secondary infertility (38/100), 15% had recurrent CSPs (RCSPs) (15/100). The reproductive outcomes of patients with CSPs after surgical treatment were not correlated with age, body mass index, time of gestation, yields, abortions, Caesarean sections, length of hospital stay, weeks of menopause during treatment, maximum diameter of the gestational sac, thickness of the remaining muscle layer of the uterine scar, type of CSP, surgical method, uterine artery embolisation during treatment, major bleeding, or presence of uterine adhesions after surgery. Abortion after treatment was the only risk factor affecting RCSPs (odds ratio 11.25, 95% confidence interval, 3.302-38.325; P < 0.01) and it had a certain predictive value for RCSP occurrence (area under the curve, 0.741). CONCLUSIONS: The recurrence probability of CSPs was low, and women with childbearing intentions after CSPs should be encouraged to become pregnant again. Abortion after CSP is a risk factor for RCSP. No significant difference in reproductive outcomes was observed between the patients who underwent ultrasound-guided uterine aspiration and those who underwent laparoscopic scar repair for CSP.

The Impact of Platelet-Rich Plasma Application during Cesarean Section on Wound Healing and Postoperative Pain: A Single-Blind Placebo-Controlled Intervention Study.

Background/Objectives: The aim of this study was to evaluate if platelet-rich plasma (PRP) application into the wound during cesarean delivery improves wound healing and reduces pain in the postoperative period. Materials and Methods: A total of 46 patients undergoing cesarean section (CS) were included in this single-blind placebo-controlled intervention study: 23 women in the PRP group and 23 in the placebo group. Every patient was asked to evaluate pain by using the Visual Analogue Scale (VAS) immediately after surgery, as well as 6 and 12 h after the surgery. The use of analgetics was also recorded. The postoperative scar was assessed using the Patient and Observer Scar Assessment Scale (POSAS). Results: There was no case of wound dehiscence in either group. Significant differences between the groups in the scar quality assessment were detected in both patient and doctor POSAS results on days 8, 30 and 90 after surgery in the favor of the PRP group. There was no difference in the pain intensity assessment on the VAS recorded after surgery, but PRP patients required fewer paracetamol doses per day than the control group. Conclusions: PRP application during CS significantly improved wound healing in both short- and long-term assessment. Although it did not influence postoperative pain intensity, it may reduce the use of analgetics after surgery.

Reducing inpatient opioid consumption after caesarean delivery: effects of an opioid stewardship programme and racial impact in a community hospital.

Caesarean section is the most common inpatient surgery in the USA, with more than 1.1 million procedures in 2020. Similar to other surgical procedures, healthcare providers rely on opioids for postoperative pain management. However, current evidence shows that postpartum patients usually experience less pain due to pregnancy-related physiological changes. Owing to the current opioid crisis, public health agencies urge providers to provide rational opioid prescriptions. In addition, a personalised postoperative opioid prescription may benefit racial minorities since research shows that this population receives fewer opioids despite greater pain levels. Our project aimed to reduce inpatient opioid consumption after caesarean delivery within 6 months of the implementation of an opioid stewardship programme.A retrospective analysis of inpatient opioid consumption after caesarean delivery was conducted to determine the baseline, design the opioid stewardship programme and set goals. The plan-do-study-act method was used to implement the programme, and the results were analysed using a controlled interrupted time-series method.After implementing the opioid stewardship programme, we observed an average of 80% reduction (ratio of geometric means 0.2; 95% CI 0.2 to 0.3; p<0.001) in inpatient opioid consumption. The institution designated as control did not experience relevant changes in inpatient opioid prescriptions during the study period. In addition, the hospital where the programme was implemented was unable to reduce the difference in inpatient opioid demand between African Americans and Caucasians.Our project showed that an opioid stewardship programme for patients undergoing caesarean delivery can effectively reduce inpatient opioid use. PDSA, as a quality improvement method, is essential to address the problem, measure the results and adjust the programme to achieve goals.

Meta-analysis comparing different ultrasound detection methods to accurately assess wound healing and scar formation after caesarean section.

The accurate assessment of wound healing post-caesarean section, especially in twin pregnancies, remains a pivotal concern in obstetrics, given its implications for maternal health and recovery. Traditional methods, including conventional abdominal ultrasonography (CU), have been challenged by the advent of transvaginal ultrasonography (TU), offering potentially enhanced sensitivity and specificity. This meta-analysis directly compares the efficacy of TU and CU in evaluating wound healing and scar formation, crucial for optimizing postoperative care. Results indicate that TU is associated with significantly better outcomes in wound healing, demonstrated by lower REEDA scores (SMD = -20.56, 95% CI: [-27.34.20, -13.77], p < 0.01), and in scar formation reduction, evidenced by lower Manchester Scar Scale scores (SMD = -25.18, 95% CI: [-29.98, -20.39], p < 0.01). These findings underscore the potential of integrating TU into routine post-caesarean evaluation protocols to enhance care quality and patient recovery.

Risk factors for relaparotomy after a cesarean delivery: a case-control study.

BACKGROUND: Relaparotomy following a cesarean delivery (CD) is an infrequent complication, with inconsistency regarding risk factors and indications for its occurrence. We therefore aimed to determine risk factors and indications for a relaparotomy following a CD at a single large tertiary center. METHODS: A retrospective case-control single-center study (2013-2023). We identified all women who had a relaparotomy up to six weeks following a CD (study group). Maternal characteristics, obstetrical and surgical data were compared to a control group in a 1:2 ratio. Controls were women with a CD before and immediately after each case in the study group, who did not undergo a relaparotomy. Included were CDs occurring after 24 gestational weeks. CD performed at different centers and indications for repeat surgery unrelated to the primary surgery (e.g., appendicitis) were excluded. Logistic regression was used to adjust for potential confounders. RESULTS: During the study period, 131,268 women delivered at our institution. Of them, 28,280 (21.5%) had a CD, and 130 patients (0.46%) underwent a relaparotomy. Relaparotomies following a CD occurred during the first 24 h, the first week, and beyond the first week, in 59.2%, 33.1%, and 7.7% of cases, respectively. In the multivariable logistic regression analysis, relaparotomy was significantly associated with Mullerian anomalies (aOR 3.33, 95%CI 1.08-10.24, p = 0.036); uterine fibroids (aOR 3.17, 95%CI 1.11-9.05,p = 0.031); multiple pregnancy (aOR 4.1, 95%CI 1.43-11.79,p = 0.009); hypertensive disorders of pregnancy (aOR 3.46, 95%CI 1.29-9.3,p = 0.014); CD during the second stage of labor (aOR 2.54, 95%CI 1.15-5.88, p = 0.029); complications during CD (aOR 1.62, 95%CI 1.09-3.21,p = 0.045); and excessive bleeding during CD or implementation of bleeding control measures (use of tranexamic acid, a hemostatic agent, or a surgical drain) (aOR 2.23, 95%CI 1.29-4.12,p = 0.012). Indications for relaparotomy differed depending on the time elapsed from the CD, with suspected intra-abdominal bleeding (36.1%) emerging as the primary indication within the initial 24 h. CONCLUSION: We detected several pregnancy, intrapartum, and intra-operative risk factors for the need for relaparotomy following a CD. Practitioners may utilize these findings to proactively identify women at risk, thereby potentially reducing their associated morbidity.

Maternal and foetal complications of pregestational and gestational diabetes: a descriptive, retrospective cohort study.

Gestational diabetes is characterized by hyperglycaemia diagnosed during pregnancy. Gestational and pregestational diabetes can have deleterious effects during pregnancy and perinatally. The baby's weight is frequently above average and might reach macrosomia (≥ 4 kg), which can reduce pregnancy time causing preterm births, and increase foetal-pelvic disproportion which often requires delivery by caesarean section. Foetal-pelvic disproportion due to the baby's weight can also cause foetal distress resulting in lower Apgar scores. To analyse the association between pregestational and gestational diabetes with maternal and foetal risk. We conducted a retrospective cohort study in women pregnant between 2012 and 2018 in the region of Lleida. Regression coefficients and 95% confidence intervals (CI) were used. The multivariate analysis showed statistically significant associations between pregestational diabetes and: prematurity (OR 2.4); caesarean section (OR 1.4); moderate (OR 1.3), high (OR 3.3) and very high (OR 1.7) risk pregnancies; and birth weight ≥ 4000 g (macrosomia) (OR 1.7). In getational diabetes the multivariate analysis show significant association with: caesarean section (OR 1.5); moderate (OR 1.7), high (OR 1.7) and very high (OR 1.8) risk pregnancies and lower 1-minuto Apgar score (OR 1.5). Pregestational and gestational diabetes increase: pregnancy risk, caesarean sections, prematurity, low Apgar scores, and macrosomia.

A combination of laparoscopy and bilateral uterine artery occlusion for the treatment of type II cesarean scar pregnancy: a retrospective analysis.

OBJECTIVE: We investigated the efficacy of a combination of laparoscopy and bilateral uterine artery occlusion (BUAO) for the treatment of type II cesarean scar pregnancy (CSP). METHODS: Patients with type II CSP underwent laparoscopy + bilateral uterine artery embolization (control group) or laparoscopy + BUAO (study group). Data regarding the duration of surgery, intraoperative hemorrhage, postoperative complications, the duration of the hospital stay, and the costs of hospitalization were retrospectively collected. One year later, the time to the return of the ß-human chorionic gonadotropin (ß-hCG) concentration to normal and to the return of menstruation were compared. RESULTS: The duration of surgery, time to the return of menstruation, and incidence of postoperative complications in the study group were significantly less than in the control group, but there was no significant difference in the time for ß-hCG to return to normal or the volume of intraoperative hemorrhage. The duration of hospitalization and costs for the control group were higher than those for the study group. CONCLUSION: Laparoscopy in combination with BUAO is associated with minimal trauma, rapid recovery, a short duration of surgery, low cost of hospitalization, and a low postoperative complication rate. Thus, it represents a useful new surgical treatment for type II CSP.

Evaluation of incision healing status after transverse uterine fundal incision for cesarean delivery and postoperative pregnancy: a ten-year single-center retrospective study.

BACKGROUND: Transverse uterine fundal incision (TUFI) is a beneficial procedure for mothers and babies at risk due to placenta previa-accreta, and has been implemented worldwide. However, the risk of uterine rupture during a subsequent pregnancy remains unclear. We therefore evaluated the TUFI wound scar to determine the approval criteria for pregnancy after this surgery. METHODS: Between April 2012 and August 2022, we performed TUFI on 150 women. Among 132 of the 150 women whose uteruses were preserved after TUFI, 84 women wished to conceive again. The wound healing status, scar thickness, and resumption of blood flow were evaluated in these women by magnetic resonance imaging (MRI) and sonohysterogram at 12 months postoperatively. Furthermore, TUFI scars were directly observed during the Cesarean sections in women who subsequently conceived. RESULTS: Twelve women were lost to follow-up and one conceived before the evaluation, therefore 71 cases were analyzed. MRI scans revealed that the "scar thickness", the thinnest part of the scar compared with the normal surrounding area, was ≥ 50% in all cases. The TUFI scars were enhanced in dynamic contrast-enhanced MRI except for four women. However, the scar thickness in these four patients was greater than 80%. Twenty-three of the 71 women conceived after TUFI and delivered live babies without notable problems until August 2022. Their MRI scans before pregnancy revealed scar thicknesses of 50-69% in two cases and ≥ 70% in the remaining 21 cases. And resumption of blood flow was confirmed in all patients except two cases whose scar thickness ≥ 90%. No evidence of scar healing failure was detected at subsequent Cesarean sections, but partial thinning was found in two patients whose scar thicknesses were 50-69%. In one woman who conceived seven months after TUFI and before the evaluation, uterine rupture occurred at 26 weeks of gestation. CONCLUSIONS: Certain criteria, including an appropriate suture method, delayed conception for at least 12 months, evaluation of the TUFI scar at 12 months postoperatively, and cautious postoperative management, must all be met in order to approve a post-TUFI pregnancy. Possible scar condition criteria for permitting a subsequent pregnancy could include the scar thickness being ≥ 70% of the surrounding area on MRI scans, at least partially resumed blood flow, and no abnormalities on the sonohysterogram. TRIAL REGISTRATION: Retrospectively registered.

Perioperative outcomes and causes of postpartum hemorrhage in patients undergoing cesarean delivery in Thailand: A comprehensive retrospective study.

BACKGROUND: This study aimed to identify the characteristics, causes, perioperative anesthetic, and obstetric outcomes of patients experiencing postpartum hemorrhage (PPH) after cesarean delivery. METHODS: We retrospectively analyzed patients who underwent cesarean delivery at the largest university hospital in Bangkok, Thailand, during a 5-year period (January 1, 2016-December 31, 2020). PPH was defined as an estimated blood loss (EBL) of ≥ 1000 ml within 24 hours postpartum. RESULTS: Of 17 187 cesarean deliveries during the study period, 649 patients were included for analysis. The mean EBL was 1774.3 ± 1564.4 ml (range: 1000-26 000 ml). Among the patients, 166 (25.6%) experienced massive PPH (blood loss > 2000 ml). Intraoperative blood transfusions were necessary for 264 patients (40.7%), while 504 individuals (77.7%) needed intraoperative vasopressors. The analysis revealed uterine atony as the leading cause of PPH in 62.7% (n = 407) of the patients, with abnormal placentation following at 29.3% (n = 190). Abnormal placentation was associated with a significantly higher mean EBL of 2345.0 ± 2303.9 ml compared to uterine atony, which had a mean EBL of 1504.0 ± 820.7 ml (P < 0.001). Abnormal placentation also significantly increased the likelihood of blood transfusions and hysterectomies (P < 0.001 for both) and led to more intensive care unit admissions (P = 0.032). The risk of EBL exceeding 2000 ml was markedly higher in patients with abnormal placentation (odds ratio [OR] 5.12, 95% confidence interval [CI] 3.45-7.57, P < 0.001) and in cases involving trauma to the internal organs (OR 2.33, 95% CI 1.16-4.71, P = 0.018) than in patients with uterine atony. The study documented three instances of perioperative cardiac arrest, one of which was fatal. CONCLUSIONS: These findings highlight the importance of comprehensive perioperative management strategies, including the ready availability of adequate blood and blood products, particularly in scenarios predisposed to significant hemorrhage. TRIAL REGISTRATION: Clinical trial registration: Clinicaltrial.gov registration number NCT04833556 (April 6, 2021).

Postoperative maternal complications of caesarean section: a cross-sectional study at the Provincial General Hospital of Kananga in the Democratic Republic of Congo.

Introduction: the maternal complications of caesarean section make it considered a riskier route of delivery than the vaginal route. The caesarean patient in fact combines the risks of giving birth and those of abdominal surgery. The objective of our study is to determine the epidemiological and therapeutic profile of postoperative maternal complications of caesarean section at the Provincial General Hospital of Kananga from January 1st, 2016 to December 31st, 2020. Methods: this is a cross-sectional study of cases of postoperative maternal complications of cesarean section, based on non-probability convenience sampling for case selection. multivariable logistic regression was used in statistical analyses. Our study sample was 302 cases. Results: the hospital frequency of postoperative complications of cesarean section is 34.12% with the annual average of 60.40 (17.21) cases per year. The postoperative infections are the most frequent complication with more than 52.98% (n=160), treatment is surgical in 59.61% (n=180), the maternal mortality rate due to postoperative complications of cesareans is 5.63% (n=17). Five factors independently associated with postoperative complications of cesarean section were identifying: prolonged labor (aOR: 3.110, 95% CI: 1.040-9.250; p=0.001), defective hygiene of patients (aOR: 1.910, 95% CI: 1.090-10.930; p=0.001), uterine overdistension before caesarean section (aOR: 4.290, 95% CI: 3.320-5.550; p=0.000), multiparity (aOR: 2.070, 95% CI: 1.010-5.210; p=0.006) and emergency cesarean section (aOR: 1.510, 95% CI: 1.250-1.910; p=0.000) in our environment and during the period of our study. Conclusion: intraoperative complications of ceasarean section constitute a real health problem. These five factors independently associated with postoperative complications of cesarean section could be used for screening of high-risk women in obstetrical consultations during pregnancy monitoring.

Neonatal outcomes in the surgical management of placenta accreta spectrum disorders: a retrospective single-center observational study from 468 Vietnamese pregnancies beyond 28 weeks of gestation.

BACKGROUND: Placenta accreta spectrum disorders (PASDs) increase the mortality rate for mothers and newborns over a decade. Thus, the purpose of the study is to evaluate the neonatal outcomes in emergency cesarean section (CS) and planned surgery as well as in Cesarean hysterectomy and the modified one-step conservative uterine surgery (MOSCUS). The secondary aim is to reveal the factors relating to poor neonatal outcomes. METHODS: This was a single-center retrospective study conducted between 2019 and 2020 at Tu Du Hospital, in the southern region of Vietnam. A total of 497 pregnant women involved in PASDs beyond 28 weeks of gestation were enrolled. The clinical outcomes concerning gestational age, birth weight, APGAR score, neonatal intervention, neonatal intensive care unit (NICU) admission, and NICU length of stay (LOS) were compared between emergency and planned surgery, between the Cesarean hysterectomy and the MOSCUS. The univariate and multivariable logistic regression were used to assess the adverse neonatal outcomes. RESULTS: Among 468 intraoperatively diagnosed PASD cases who underwent CS under general anesthesia, neonatal outcomes in the emergency CS (n = 65) were significantly poorer than in planned delivery (n = 403). Emergency CS increased the odds ratio (OR) for earlier gestational age, lower birthweight, lower APGAR score at 5 min, higher rate of neonatal intervention, NICU admission, and longer NICU LOS ≥ 7 days with OR, 95% confidence interval (CI) were 10.743 (5.675-20.338), 3.823 (2.197-6.651), 5.215 (2.277-11.942), 2.256 (1.318-3.861), 2.177 (1.262-3.756), 3.613 (2.052-6.363), and 2.298 (1.140-4.630), respectively, p < 0.05. Conversely, there was no statistically significant difference between the neonatal outcomes in Cesarean hysterectomy (n = 79) and the MOSCUS method (n = 217). Using the multivariable logistic regression, factors independently associated with the 5-min-APGAR score of less than 7 points were time duration from the skin incision to fetal delivery (min) and gestational age (week). One minute-decreased time duration from skin incision to fetal delivery contributed to reduce the risk of adverse neonatal outcome by 2.2% with adjusted OR, 95% CI: 0.978 (0.962-0.993), p = 0.006. Meanwhile, one week-decreased gestational age increased approximately two fold odds of the adverse neonatal outcome with adjusted OR, 95% CI: 1.983 (1.600-2.456), p < 0.0001. CONCLUSIONS: Among pregnancies with PASDs, the neonatal outcomes are worse in the emergency group compared to planned group of cesarean section. Additionally, the neonatal comorbidities in the conservative surgery using the MOSCUS method are similar to Cesarean hysterectomy. Time duration from the skin incision to fetal delivery and gestational age may be considered in PASD surgery. Further data is required to strengthen these findings.

Prediction of Intraperitoneal Adhesions in Repeated Cesarean Deliveries with Stria Gravidarum Scoring System: A Cross-sectional Study.

BACKGROUND: The preoperative prediction of intraperitoneal adhesion (IPA) before repeated cesarean deliveries (CD), which are becoming more prevalent, is crucial for maternal health. AIM: The aim of the study was to preoperatively predict IPA in repeated CD with the stria gravidarum (SG) scoring system. METHODS: A total of 167 patients with at least one previous CD at or beyond 37 weeks of gestation were analyzed. Preoperative SG was calculated according to the Davey scoring system: 0-2 score were defined as mild SG (Group 1; n: 94, 56.2%), and 3-8 score were defined as severe SG (Group 2; n = 73, 43.8%). Preoperative previous cesarean incision features were evaluated according to the Vancouver scar scale. IPA was evaluated according to the Nair's and modified Nair's scoring systems. RESULTS: Parity, younger age at first pregnancy, higher body mass index, number of previous CDs, rate of scar symptoms, Nair's and the modified Nair's scores were statistically significant in Group 2 (P = 0.01; P = 0.04; P = 0.007; P = 0.004; P < 0.001; P = 0.007; P = 0.02, respectively). Davey score ≥3 and Vancouver score ≥4.5 were determined as the cut-off value to predict IPA (P = 0.1 and 0.07, respectively). According to multivariate analysis, both Davey and Vancouver scores are independent factors in predicting IPA (P = 0.02 and 0.04, respectively). CONCLUSION: Evaluating the SG score through the Davey score in women with a history of previous CD may assist in predicting IPA status before the planning of a subsequent surgery.

Reflections on Postpartum Hysterectomy as a Possible Complication of Cesarean Myomectomy: A Long Debate.

Uterine fibroids are common benign tumors found in fertile women. Numerous obstetrical issues, such as dystocia during labor, fetal hypotrophy, a ruptured amniotic sac, early labor, low-birth-weight newborns, etc., are associated with fibrous pregnant uteri. Cesarean myomectomy is not a common procedure because of the possibility of postpartum hysterectomy or a potentially lethal hemorrhage. For the chosen topic, we present two instances of emergency postpartum hysterectomies following cesarean myomectomy. After a cesarean myomectomy, two women experienced a perioperative hemorrhage that required a postpartum hysterectomy without a salpingo-oophorectomy. A postpartum hysterectomy was required in every instance due to the failure of additional hemostatic techniques to control the bleeding after the cesarean myomectomy. In every case, the location and number of fibroids-rather than their size-were the primary factors leading to the postpartum hysterectomy. In order to ensure that the patient is safe and that the advantages outweigh the dangers, the current trends in cesarean myomectomy include aiming to conduct the procedure either electively or when it offers an opportunity. The treatment is still up for debate because it is unknown how dangerous a second hysterectomy is for people who have had a cesarean myomectomy.

Uterine Cesarean Scar Tissue-An Immunohistochemical Study.

Background and Objectives: Wound healing encompasses a multitude of factors and entails the establishment of interactions among components of the basement membrane. The quantification of particle concentrations can serve as valuable biomarkers for assessing biomechanical muscle properties. The objective of this study was to examine the immunoexpression and immunoconcentration of myometrial collagen type VI, elastin, alpha-smooth muscle actin, and smooth muscle myosin heavy chain, as well as the expression of platelets and clusters of differentiation 31 in the uterine scar following a cesarean section (CS). Materials and Methods: A total of 177 biopsies were procured from a cohort of pregnant women who were healthy, specifically during the surgical procedure of CS. The participants were categorized into seven distinct groups. Group 1 consisted of primiparas, with a total of 52 individuals. The subsequent groups were organized based on the duration of time that had elapsed since their previous CS. The analysis focused on the immunoexpression and immunoconcentration of the particles listed. Results: No significant variations were observed in the myometrial immunoconcentration of collagen type VI, elastin, smooth muscle myosin, and endothelial cell cluster of differentiation 31 among the analyzed groups. The concentration of alpha-smooth muscle actin in the myometrium was found to be significantly higher in patients who underwent CS within a period of less than 2 years since their previous CS, compared to those with a longer interval between procedures. Conclusions: Our findings indicate that the immunoconcentration of uterine myometrial scar collagen type VI, elastin, smooth muscle myosin heavy chain, alpha-smooth muscle actin, and endothelial cell marker cluster of differentiation 31 remains consistent regardless of the duration elapsed since the previous CS. The findings indicate that there are no significant alterations in the biomechanical properties of the uterine muscle beyond a period of 13 months following a CS.

Association between Antenatal Vaginal Bleeding and Adverse Perinatal Outcomes in Placenta Accreta Spectrum.

Background and Objectives: Placenta accreta spectrum (PAS) disorders are placental conditions associated with significant maternal morbidity and mortality. While antenatal vaginal bleeding in the setting of PAS is common, the implications of this on overall outcomes remain unknown. Our primary objective was to identify the implications of antenatal vaginal bleeding in the setting of suspected PAS on both maternal and fetal outcomes. Materials and Methods: We performed a case-control study of patients referred to our PAS center of excellence delivered by cesarean hysterectomy from 2012 to 2022. Subsequently, antenatal vaginal bleeding episodes were quantified, and components of maternal morbidity were assessed. A maternal composite of surgical morbidity was utilized, comprised of blood loss ≥ 2 L, transfusion ≥ 4 units of blood, intensive care unit (ICU) admission, and post-operative length of stay ≥ 4 days. Results: During the time period, 135 cases of confirmed PAS were managed by cesarean hysterectomy. A total of 61/135 (45.2%) had at least one episode of bleeding antenatally, and 36 (59%) of these had two or more bleeding episodes. Increasing episodes of antenatal vaginal bleeding were associated with emergent delivery (p < 0.01), delivery at an earlier gestational age (35 vs. 34 vs. 33 weeks, p < 0.01), and increased composite maternal morbidity (76, 84, and 94%, p = 0.03). Conclusions: Antenatal vaginal bleeding in the setting of PAS is associated with increased emergent deliveries, earlier gestational ages, and maternal composite morbidity. This important antenatal event may aid in not only counseling patients but also in the coordination of multidisciplinary teams caring for these complex patients.

Effect of epidural dexmedetomidine in single-dose combined with ropivacaine for cesarean section.

BACKGROUND: Dexmedetomidine has arousal sedation and analgesic effects. We hypothesize that epidural dexmedetomidine in single-dose combined with ropivacaine improves the experience of parturient undergoing cesarean section under epidural anesthesia. This study is to investigate the effect of 0.5 µg/kg epidural dexmedetomidine combined with epidural anesthesia (EA) in parturients undergoing cesarean section. METHODS: A total of 92 parturients were randomly divided into Group R (receiveing epidural ropivacaine alone) Group RD (receiveing epidural ropivacaine with 0.5 µg/kg dexmedetomidine). The primary outcome and second outcome will be intraoperative NRS pain scores and Ramsay Sedation Scale. RESULTS: All 92 parturients were included in the analysis. The NRS were significantly lower in Group RD compared to Group R at all observation timepoint (P > 0.05). Higher Ramsay Sedation Scale was found in Group RD compared to Group R (P < 0.001). No parturient has experienced sedation score of 4 and above. No significant difference regarding the incidence of hypotension, bradycardia and nausea or vomiting, Apgar scores and the overall satisfaction with anesthesia was found between Group R and Group RD (P > 0.05). CONCLUSION: Epidural dexmedetomidine of 0.5 µg/kg added slightly extra analgesic effect to ropivacaine in EA for cesarean section. The sedation of 0.5 µg/kg epidural dexmedetomidine did not cause mother-baby bonding deficit. Satisfaction with anesthesia wasn't significantly improved by epidural dexmedetomidine of 0.5 µg/kg. No additional side effect allows larger dose of epidural dexmedetomidine attempt. TRIAL REGISTRATION: This study was registered at www.chictr.org.cn (ChiCTR2000038853).
