Improved obstetric management after implementation of a scaled-up quality improvement intervention: A nested before-after study in three public hospitals in Nepal

BACKGROUND

We assessed the change in obstetric management after implementation of a quality improvement intervention, the Nepal Perinatal Quality Improvement Package (NePeriQIP).

METHODS

The Nepal Perinatal Quality Improvement Package was a stepped-wedge cluster-randomized controlled trial conducted in 12 public hospitals in Nepal between April 2017 and October 2018. In this study, three hospitals allocated at different time points to the intervention were selected for a nested before-after analysis. We used bivariate and multivariate analyses to compare obstetric management in the control vs intervention group.

RESULTS

There were 25 977 deliveries in the three hospitals during the study period: 10 207 (39%) in the control and 15 770 (61%) in the intervention group. After adjusting for maternal age, ethnicity, education, gestational age, stage of labor at admission, complications during labor, and birthweight, the intervention group had a higher proportion of fetal heart rate monitoring performed as per protocol (adjusted odds ratio [aOR] 1.19, 95% confidence interval [CI] 1.12-1.27), shorter time intervals between each fetal heart rate monitoring (aOR 2.09, 95% CI 1.96-2.23), a higher likelihood of abnormal fetal heart rate being detected (aOR 1.53, 95% CI 1.25-1.68), progress of labor more often being recorded immediately after per vaginal examination (aOR 2.73, 95% CI 2.55-2.93), and partograph filled as per standards (aOR 3.18, 95% CI 2.98-3.50). The cesarean birth rate was 2.5% in the control group and 8.2% in the intervention group (aOR 3.12, 95% CI 2.64-3.68).

CONCLUSIONS

The NePeriQIP intervention has potential to improve obstetric care, especially intrapartum fetal surveillance, in similar low-resource settings.

Influence on operative time of immediate skin-to-skin care in low-risk primary cesarean births for breech presentation: Retrospective cohort study

BACKGROUND

Multiple benefits for both, mother and baby have been reported from immediate skin-to-skin care (SSC). The aim of this study was to analyze the influence of SSC on operative time and blood loss in primary cesarean births for breech presentation.

METHODS

A SSC protocol for cesarean birth was implemented in our institution on February 25, 2019. In this single-center retrospective cohort study, we compared the outcomes of planned primary cesarean births for breech presentation at term before and after its implementation.

RESULTS

Data from 110 women who had a cesarean birth for breech presentation at term were analyzed, 55 in each group. Group 1 were women who had immediate SSC and Group 2 were women without immediate SSC. Maternal and surgical characteristics, and neonatal outcomes were similar in both groups. The mean operative time was 3.22 minutes shorter in the immediate SSC group compared with the not immediate SSC group (37.13 ± 12.27 vs 40.35 ± 12.23 minutes; P = 0.171).

CONCLUSIONS

In conclusion, immediate SSC following a low-risk cesarean birth for breech presentation neither prolongs the operative time nor increases blood loss during the procedure. Although we were unable to demonstrate a significant reduction in the operative time with the immediate SSC protocol, a decrease of 3 minutes was noted.

Midwifery Workforce Density Moderates the Association Between Independent Practice and Pregnancy Outcomes

INTRODUCTION

Studies comparing pregnancy outcomes before and after state transition to independent midwifery practice have found little change in primary cesarean birth and preterm birth rates. One reason may be the failure to control for midwife density. The objective was to test if the local midwife density moderates the association between state independent midwifery practice and pregnancy outcomes.

METHODS

Birth records were abstracted from the State Inpatient Databases for 6 states. The Area Health Resource File provided county variables. Midwife density was operationalized as no midwives, low midwife density (<4.5 per 1000 births), and high midwife density (≥4.5 midwives per 1000 births). Multivariate logistic regression models compared primary cesarean birth and preterm birth, controlling for maternal and county characteristics. Moderation was tested by including an interaction term (independent practice × density) to the regression models. The magnitude of association for the interaction was measured by stratifying the models.

RESULTS

The study included 875,156 women; most (79.7%) resided in a county with low midwife density. Restricted midwifery practice was associated with increased odds of both primary cesarean birth and preterm birth. The interaction term was significant for both preterm birth and primary cesarean, indicating moderation. The largest magnitude of difference was the increased odds of preterm birth in counties with a high midwife density and restricted practice (odds ratio, 3.50; 95% CI, 2.43-5.06) compared with those with high midwife density and independent practice.

DISCUSSION

Midwife density moderates the association between independent midwifery practice and primary cesarean birth and preterm birth. Moderation may explain why prior studies found small or no changes in outcomes when states adopted independent practice. Moderation models can improve testing for associations with independent practice. Both midwife independent practice and increasing midwifery workforce size can be strategies to improve state pregnancy outcomes.

Anesthetic drug concentrations and placental transfer rate in fetus between term and preterm infants, twins, and singletons

Objective: This study aims to determine the drug concentration of etomidate, remifentanil, and rocuronium bromide for general anesthesia in fetus as well as the placental transport rate between term and preterm delivery, twins, and singleton. Study design: Sixty parturients with 72 fetuses undergoing cesarean section under general anesthesia were included. According to whether the fetus was a twin or premature, parturients were divided into Group I (term singleton), Group II (premature singleton), Group III (term twins), and Group IV (premature twins). The preoperative demographic characteristics and laboratory examination of parturients, hemodynamic indicators, the Apgar score of neonates at 1, 5, and 10 min after delivery and at specific assigned values, umbilical artery blood gas analysis results, neonatal weight, and resuscitative measures were recorded. Anesthetic drug concentrations in maternal arterial (MA), umbilical arterial (UA), and umbilical venous (UV) blood were detected by Ultra Performance Liquid Chromatography Tandem Mass Spectrometry (UPLC-MS/MS). Result: No significant differences were observed in the concentrations of etomidate, remifentanil, and rocuronium bromide in MA, UV, and UA blood, or in the UV/MA and UA/UV ratios between term and preterm infants, twins, and singletons. Moreover, there was no variation in the anesthetic drug concentration among each pair of twins. Additionally, no correlation was found between the neonatal weight and the plasma concentrations of anesthetic drugs in UV and UA blood, except for remifentanil in UA blood. Conclusion: Preterm or twin deliveries do not affect the neonatal concentration of etomidate, remifentanil, and rocuronium bromide used in general anesthesia for cesarean sections.

Neonatal Outcome of Mothers With COVID-19 in King Salman Armed Forces Hospital, Tabuk, Kingdom of Saudi Arabia

OBJECTIVES

This study was conducted to assess the neonatal outcome of mothers with COVID-19 in King Salman Armed Forces Hospital, Tabuk, Saudi Arabia.

METHODS

This was a hospital record-based, retrospective cohort study. The case group included neonates born to mothers who were positive for the COVID-19 virus during pregnancy, whereas the control group included neonates born to mothers who were not infected with the COVID-19 virus during pregnancy. The data were collected from the records and were analyzed using the Statistical Package for the Social Sciences software (IBM Corp., Armonk, NY, USA).

RESULTS

This study covered the hospital records of 342 women (114 cases and 228 control). The rates of cesarean sections and small for gestational age were significantly higher among the cases compared to the controls (71.1% versus 43.4%, p < 0.001 and 24.6% versus 11.8%, p = 0.003; respectively). The mean birth weight was significantly lower among the cases group (3.0 ± 0.6 versus 3.3 ± 0.6 kg, p = 0.022). Only the case group reported the occurrence of neonatal COVID-19 infection (7.9%, p < 0.001). The study reported only a single case of intrauterine fetal death and one stillbirth in the cases group, but no neonatal deaths (p > 0.05).

CONCLUSIONS

Maternal COVID-19 may be associated with undesirable neonatal outcomes. There is a possibility of vertical transmission of COVID-19 from the mother to the neonate, but this cannot be confirmed.

Diagnosis and Management of Cesarean Scar Ectopic Pregnancy: A Case Study

A cesarean scar ectopic pregnancy (CSEP) designates an ectopic pregnancy within the myometrium of a past uterine incision. Early diagnosis through transvaginal ultrasonography is crucial as an untreated CSEP can lead to serious complications, including hemorrhage, loss of future fertility, and maternal death. We present a case of a 33-year-old female with five previous cesarean sections, who presented at seven weeks of gestation with concerns of a CSEP. Here, we highlight the importance of early diagnosis and maintaining high clinical suspicion in women with multiple previous cesarean sections who present with menstrual abnormalities. The CSEP is a serious condition and requires a high index of suspicion during diagnosis and follow-up. Ultrasound scanning and training should be readily available to quickly identify and treat this life-threatening condition.

Vaginal delivery rate by near delivery sonographic weight estimation and maternal stature among nulliparous women

BACKGROUND

We evaluated the risk for cesarean delivery among term nulliparous women, categorized by maternal stature and recent sonographic estimated fetal weight (EFW).

METHODS

A retrospective study including singleton deliveries of nulliparous women between 2011 and 2020, with sonographic EFW within 1 week of delivery. We categorized maternal height into five groups: ≤150, 151-155, 156-160, 161-165, and ≥166 cm. Fetal weight estimation was categorized into five groups as well: ≤2500 g, 2501-2999, 3000-3499, 3500-3999, and ≥4000 g.

RESULTS

Overall, 13 107 deliveries were included. The cesarean delivery rate was inversely correlated with maternal height, ranging from 41.0% in group 1 to 13.1% in group 5. The vaginal delivery rate ranged from 33.3% in maternal height group 1 with EFW of ≥4000 g to 85% in maternal height group 5 with EFW of ≤2500 g. In weight categories above 2500 g, maternal height correlated significantly with vaginal delivery rate, except in weight category ≥4000 g in which vaginal delivery rate ranged around 30% in maternal height categories 1-3 and increased significantly in groups 4-5 to 50-60%. In multivariable logistic regression analysis, EFW was independently associated with CD for EFW categories 3500-3999 and ≥4000 g [aOR 95% CI 1.49 (1.08-2.06) and 4.39 (2.97-6.50), respectively]. Maternal height was negatively associated with CD [aOR 95% CI 0.67 (0.64-0.70)] for each increase in maternal height group.

CONCLUSIONS

Cesarean delivery rate was inversely correlated with maternal height, ranging from 41.0% among women ≤150 cm to 13.1% among women ≥166 cm. Maternal height and EFW of ≥3500 g are independently associated with CD rates among term nulliparous women.

Successful Non-surgical Management of Cesarean Scar Pregnancy

Ectopic pregnancy in the scar of a previous cesarean section contributes to significant maternal morbidity in the first trimester due to a significantly higher risk of uterine rupture if left undetected. The routine scans done in the first trimester serve as an important screening tool in the detection of such an ectopic pregnancy. Early detection can aid in making a paradigm shift from a surgical to a more conservative approach for the management of such pregnancies. Here, we report a case of a cesarean scar pregnancy diagnosed in the sixth week of gestation which was managed non-surgically with methotrexate and intracardiac potassium chloride injection.

Asymptomatic Patient With Incarcerated Gravid Uterus Diagnosed in the Third Trimester: A Case Report of a Rare Potential Obstetric Emergency

Incarcerated gravid uterus (IGU) is a rare condition that occurs when a retropositioned gravid uterus becomes entrapped within the pelvic cavity. Most patients present around the 17th week of pregnancy with symptoms such as pelvic fullness, urinary incontinence, abdominal pain, constipation, and vaginal bleeding. Rarely, patients are asymptomatic throughout pregnancy, leaving IGU undiagnosed and untreated. Here, we present an asymptomatic 26-year-old female who presented at 30 weeks of gestation with severe intrauterine growth retardation (IUGR) on serial obstetric ultrasounds. Further evaluation with ultrasound and MRI revealed an incarcerated uterus. This was complicated by severe fetal IUGR, abnormal biophysical profile, and oligohydramnios. This case highlights the importance of early diagnosis and treatment of IGU in order to prevent complications associated with the condition. Clinicians should be aware that, although uncommon, patients with IGU may be asymptomatic and that diagnosis should depend primarily on imaging findings rather than symptoms.

Inter-rater agreement of CDC criteria and ASEPSIS score in assessing surgical site infections after cesarean section: a prospective observational study

Objective

To assess and compare the inter-rater agreement of the CDC criteria and the ASEPSIS score in identifying surgical site infections after cesarean section.

Methods

Prospective observational study including 110 patients subjected to a cesarean section at our institution. Surgical wounds were managed according to standard care and were photographed on the third, seventh, and thirtieth postoperative day or during any evaluation in case of complications. Three expert surgeons reviewed the prospectively gathered data and photographs and classified each wound using CDC criteria and the ASEPSIS score. The inter-rater agreements of CDC criteria and ASEPSIS score were determined with Krippendorff's Alpha with linear weights and compared with a confidence interval approach.

Results

The weighted α coefficient for CDC criteria was 0.587 (95%CI, 0.411-0.763, p < 0.001, "moderate" agreement according to Altman's interpretation of weighted agreement coefficient), while the weighted α coefficient for the ASEPSIS score was 0.856 (95%CI, 0.733-0.980, p < 0.001, "very good" agreement).

Conclusion

ASEPSIS score presents a "very good" inter-rater agreement for surgical site infections identification after cesarean, resulting in a more objective method than CDC criteria ("moderate" inter-rater agreement). ASEPSIS score could represent an objective tool for managing and monitoring surgical site infections after cesarean section, also by photographic evaluation.

SARS-CoV-2 infection during pregnancy - single-center retrospective study

OBJECTIVES

The SARS-CoV-2 virus infection has spread to almost all countries in the last two years. Pregnancy complicated with COVID-19 is a unique situation and challenge for doctors. The study aimed to evaluate obstetric results, and biochemical test results and to analyze the treatment used in pregnant patients complicated with COVID-19 infection.

MATERIAL AND METHODS

A retrospective analysis of 146 pregnant patients hospitalized at the Department of Obstetrics and Perinatology Jagiellonian University Medical College (JUMC) in Krakow was conducted from July 2020 to August 2021.

RESULTS

In the analyzed group respiratory failure occurred in 19.19% of cases and intravascular coagulation syndrome (DIC) in 1.37%. One patient died (0.68%). 16.6% of cases were transferred to the Intensive Care Unit (ICU) and required intubation. The remaining cases were mild: 39.04% were asymptomatic, 41.78% reported cough, 30.82% dyspnoea and 23.97% myalgia. In the laboratory tests increased values of CRP and IL-6 were observed with normal levels of leukocytes. Additionally, a decreased level of total protein and an increased level of d-dimers were detected. 98.63% of patients received a prophylactic dose of low molecular weight heparin. 46.58% of cases needed additional antibiotic therapy. Cesarean sections were performed in 59.59% of cases. The children were born in good general condition. Vertical transmission of SARS-CoV-2 to the newborn has not been confirmed.

CONCLUSIONS

Data from the above study show a significant effect of COVID-19 on pregnant patients. Almost one in five pregnant women occurred respiratory failure and most of them had to be transferred to the ICU department and had to be intubated.

Gynecological Fistulae-Has Anything Changed in the Diagnosis and Treatment over the Last Decade? A Narrative Literature Review

Gynecological fistulae are a rare but severe complication of radiation therapy, pelvic surgery, prolonged labor, cesarean deliveries, or inflammatory bowel diseases. A gynecological fistula is an abnormal pathway formed between the urinary and gynecological tract, most commonly located between the urinary bladder and vagina. Vesico-uterine and vesicovaginal fistulae are an important health issue, common in women of reproductive age in developing countries with limited access to obstetrical care. Various surgical techniques have been described for VVF repair, depending on the location, severity, and cause of the fistula and the surgeon's experience. The purpose of our review was to evaluate the present state of knowledge about the prevalence and treatment of gynecological fistulae. The PubMed scientific database was searched for original articles on the subject of gynecological fistulae that had been published between 2013 and 2023.

Prophylactic Administration of Tranexamic Acid Reduces Blood Products' Transfusion and Intensive Care Admission in Women Undergoing High-Risk Cesarean Sections

Postpartum hemorrhage (PPH) remains a major cause of maternal mortality. Tranexamic acid (TxA) has shown effectiveness in reducing PPH-related maternal bleeding events and deaths. We conducted a cohort study including parturient women at high risk of bleeding after undergoing a cesarean section (CS). Participants were divided into two groups: the treatment group received prophylactic 1-g TxA before surgery (n = 500), while the comparison group underwent CS without TxA treatment (n = 500). The primary outcome measured increased maternal blood loss following CS, defined as more than a 10% drop in hemoglobin concentration within 24 h post-CS and/or a drop of ≥2 g/dL in maternal hemoglobin concentration. Secondary outcomes included PPH indicators, ICU admission, hospital stay, TxA complications, and neonatal data. TxA administration significantly reduced hemoglobin decrease by more than 10%: there was a 35.4% decrease in the TxA group vs. a 59.4% decrease in the non-TxA group, p < 0.0001 and hemoglobin decreased by ≥2 g/dL (11.4% in the TxA group vs. 25.2% in non-TxA group, p < 0.0001), reduced packed red blood cell transfusion (p = 0.0174), and resulted in lower ICU admission rates (p = 0.034) and shorter hospitalization (p < 0.0001). Complication rates and neonatal outcomes did not differ significantly. In conclusion, prophylactic TxA administration during high-risk CS may effectively reduce blood loss, providing a potential intervention to improve maternal outcomes.

Impact of planned versus emergency cesarean delivery on neonatal outcomes in pregnancies complicated by abnormal placentation: A systematic review and meta-analysis

BACKGROUND

Although planned cesarean delivery (PCD) is the mainstay of management for abnormal placentation, some patients still require emergency cesarean delivery (ECD). We aimed to systematically analyze the impact of various modes of delivery on neonatal outcomes.

METHODS

This study was complied with the PRISMA guidelines and was registered in the PROSPERO (code: CRD42022379487). A systematic search was conducted on Ovid MEDLINE and Embase, Web of Science, PubMed, and the Cochrane databases. Data extracted included gestational age at delivery, birth weight, the Apgar scores at 1 and 5 minutes, numbers of newborns with low Apgar score (<7) at 5 minutes, the rates of neonatal intensive care unit admission, and the rates of neonatal mortality.

RESULTS

Fifteen cohort studies met the inclusion criteria, comprising a total of 2565 women (2567 neonates) who underwent PCD (n = 1483) or ECD (n = 1082) for prenatally diagnosed placenta accreta spectrum (PAS) and/or placenta previa (PP). Compared with the ECD group, neonates in the PCD group had significantly higher gestational ages (standardized mean difference [SMD]: 2.20; 95% confidence interval [CI]: 1.25-3.15; P < .001), birth weights (SMD: 1.64; 95% CI: 1.00-2.27; P < .001), and Apgar scores at 1 minute (SMD: 0.51; 95% CI: 0.29-0.73; P < .001) and 5 minutes (SMD: 0.47; 95% CI: 0.25-0.70; P < .001). Additionally, the PCD group had significantly lower rates of neonatal intensive care unit admission (odds ratio [OR]: 0.21; 95% CI: 0.14-0.29; P < .001), low Apgar score at 5 minutes (OR: 0.27; 95% CI: 0.11-0.69; P = .01), and neonatal mortality (OR: 0.13; 95% CI: 0.05-0.33; P < .001).

CONCLUSION

When pregnancies are complicated by abnormal placentation, PCD is linked to noticeably better neonatal outcomes than emergent delivery.

Effect of excessive gestational weight gain before and after 28 weeks on trial of labor after cesarean stratified by pre-pregnancy body mass index: a retrospective cohort study

This study aimed to assess the effect of excessive gestational weight gain (GWG) before and after 28 weeks on the mode of delivery in women who attempted a trial of labor after cesarean (TOLAC), stratified by pre-pregnancy BMI. A retrospective analysis of the outcomes of eligible women who attempted trial of labor after cesarean (TOLAC) in a Chinese hospital from January 2016 to October 2022 was performed. GWG before and after 28 weeks was categorized as 'excessive' or 'non-excessive' based on the guideline of Institute of Medicine (IOM). Multivariable logistic regression analyses were used to estimate the effect of excessive GWG before and after 28 weeks on mode of delivery in women who underwent TOLAC, stratified by pre-pregnancy BMI. Of the 512 women who underwent term trial of labor, 71.1% achieved a vaginal birth. No correlation was found between excessive GWG before 28 weeks and the rate of vaginal birth after cesarean (VBAC). Among women with or without excessive GWG before 28 weeks, excessive GWG after 28 weeks was significantly associated with a reduced rate of VBAC. When stratified by pre-pregnancy BMI, women who had excessive gestational weight gain after 28 weeks gestation had lower rates of VBAC than those who did not, regardless of being underweight, normal or overweight (aOR 0.23, 95% CI 0.06-0.88; aOR 0.42, 95% CI 0.25, 0.70; and aOR 0.12, 95% CI 0.04-0.36; respectively). Excessive weight gain after 28 weeks of pregnancy was related to decreased rates of VBAC, irrespective of pre-pregnancy weight status and weight gain before 28 weeks.

Factors affecting elective cesarean section in women with multiple pregnancy in Caruban, Indonesia

Background: Caesarean sections have become the most popular method for delivering twin babies because of the safety concerns associated with a natural birth. This study aims to identify the maternal characteristics and obstetric parameters that serve as risk factors influencing caesarean delivery in twin pregnancies by comparing women delivering via caesarean section and vaginal birth. Methods: A retrospective chart review design was used to analyse 47 women with multiple pregnancies from the medical records at a primary referral hospital in East Java, Indonesia. Women delivering vaginally were then compared with women who underwent a caesarean section to identify any differences between the groups. Results: In our study, more women delivered by caesarean section (n=35) than by vaginal birth (n=12). Women were more likely to undergo a caesarean section if they had a previous history of undergoing a caesarean section (OR 16.5; 95% CI 1.91-142.49; p=0.02). Similar to previous studies, we found that foetal malpresentation significantly increase the risk of caesarean delivery (OR 8.25; 95%CI 0.95-71.09; p=0.03), while labour augmentation decrease the likelihood of caesarean section (OR 0.20; 95% CI 0.49-0.81; p=0.03). There was also a significant older patients in the caesarean section groups (OR 1.26; 95% CI 1.09-1.45 ; p=0.00). Conclusions: The percentage of multiple pregnancies delivered via caesarean section is quite high. Other larger cohort study are warranted, since many factors were involved in the decision of caesarean section.

Maternal complications and associated factors among mothers who underwent a cesarean section at Gebretsadik Shewa general hospital: an institution based cross-sectional study

Introduction

Cesarean sections have played a major role in lowering maternal morbidity and mortality rates, but are a major concern in developing countries. This study aims to assess the magnitude of maternal complication and its associated factors among women who underwent a cesarean section at Gebretsadik Shewa general hospital, Southwest Ethiopia.

Method

A hospital-based cross-sectional study was conducted in Gebretsadik Shewa general hospital. Data were extracted from 382 mothers' medical charts, retrieved from the labor and operations theatre log book registry using systematic random sampling technique. The extracted data was coded and entered into Epi Data version 3.0, and exported to Statistical Package for Social Sciences (SPSS) version 20 for analysis. Logistic regression analysis was conducted and significance and strength association was determined considering AOR with a 95% confidence level.

Result

A total of 382 mothers' charts were reviewed; however, 368 charts were eligible for data entry. The age of the participants ranges between 16 and 42 years with mean and standard deviation of 26.1 ± 4.8 years. Maternal complication rate was 30.4% [95% CI: 25.8- 35.1]. Surgical site infection (10.3%), anemia (6.5%) and intraoperative bleeding (4.6%) were the most common. Multivariable logistic regression analysis showed that no antenatal care follow up, medical illness during pregnancy, emergency cesarean section and not receiving a prophylactic antibiotic were statistically associated with maternal complications.

Conclusion

The incidence of maternal complication following cesarean delivery was unduly high. Community based education about antenatal care follow up and its importance should be further strengthened for favorable maternal and fetal outcomes.

Eight-Year Trends in the Effect of the Great East Japan Earthquake on Obstetrics Outcomes: A Study from the Fukushima Health Management Survey

Information regarding the longitudinal effects of natural/environmental disasters on obstetrics outcomes is limited. This study aimed to analyze the longitudinal changes in obstetrics outcomes over 8 years after the Great East Japan Earthquake and the Fukushima power plant accident. We used data from the first 8 years of the Pregnancy and Birth Survey by the Fukushima prefectural government, launched in 2011. We compared data on obstetrics outcomes by year and divided Fukushima Prefecture into six districts based on administrative districts. Longitudinal changes in the occurrence of preterm birth before 37 gestational weeks, low birth weight, and anomalies in newborns were accessed using the Mantel-Haenszel test for trends in all six districts. Overall, 57,537 participants were included. In 8 years, maternal age, conception rate after sterility treatment, and cesarean section delivery incidence increased. Although significant differences were observed in preterm birth and low birth weight occurrence among districts, there was no significant trend in the occurrence of preterm birth, low birth weight, and anomalies in newborns in all six districts of Fukushima Prefecture. The Great East Japan Earthquake and Fukushima power plant accident were associated with increased cesarean section delivery incidence but had no significant adverse effects on obstetrics outcomes.

[Acute pancreatitis after cesarean section]

The prevalence of acute pancreatitis in pregnancy is low; similarly to the non-pregnant population, the outcome varies from mild to fatal forms. Occurrence of the disease in pregnancy is mostly in the third trimester or the postpartum period. The most common cause of acute pancreatitis is cholelithiasis but hypertriglyceridemia, fatty diet, obesity and alcohol consumption are further predisposing factors. A 27-year-old twin-pregnant woman developed acute severe pain 2 days after a cesarean section. Labor tests showed elevated amylase (1080 U/L) and lipase (2670 U/L) serum levels. For the purpose of pain relief, we inserted an epidural catheter and indicated an abdominal computer tomography examination. The abdominal imaging did not show morphological disorder of the pancreas or cholangial obstruction. We performed conservative therapy, early per os feeding, pain relief and fluid resuscitation. On the postpartum 7. day, the serum pancreas enzyme levels decreased to normal and the patient - with her babies - was discharged home. Though acute pancreatitis is a rare event in pregnancy, we should consider it in cases with acute, typical or non-typical pain. It is challenging to differentiate the disease from the acute syndromes of pregnancy. Orv Hetil. 2023; 164(31): 1231-1234.

Influence of Physical Activity during Pregnancy on Type and Duration of Delivery, and Epidural Use: Systematic Review and Meta-Analysis

Cesarean delivery may increase the need for anesthesia administration, thereby causing potential risks to both maternal and fetal health. This article aimed to investigate the effect of physical activity during pregnancy on the type of delivery, the duration of labor, and the use of epidurals (registration No.: CRD42022370646). Furthermore, 57 RCTs (n = 15301) were included showing that physical activity could decrease the risk of cesarean section (z = 3.22, p = 0.001; RR = 0.87, 95% CI = 0.79, 0.95, I2 = 37%, Pheterogeneity = 0.004), and 32 RCTs (n = 9468) showed significant decreases in instrumental delivery through performing physical activity (z = 3.48, p < 0.001; RR = 0.84, 95% CI = 0.76, 0.93, I2 = 0%, Pheterogeneity = 0.63). A significant decrease in the 15 RCTs' (n = 4797) duration of first stage labor was found in physically active pregnant women (z = 2.09, p = 0.04; MD = -62.26, 95% CI = -120.66, -3.85, I2 = 93%, Pheterogeneity < 0.001) compared to those not active. Prenatal physical activity could decrease the risk of cesarean section and instrumental delivery and the duration of first stage labor.

Predictive Efficacy of the Perfusion Index for Hypotension following Spinal Anesthesia in Parturient Undergoing Elective Cesarean Section: A Systematic Review and Meta-Analysis

This meta-analysis assessed the predictive efficacy of perfusion index for hypotension following spinal anesthesia (SA) in parturients undergoing elective cesarean section (CS). Electronic databases, including Google Scholar, EMBASE, Cochrane Library, and MEDLINE, were searched from inception to June 2023. The primary outcome was the diagnostic accuracy of the perfusion index in predicting the probability of perioperative hypotension following SA. The review included 12 studies involving 2009 patients, published between 2017 and 2023. The pooled sensitivity and specificity were 0.81 (95% confidence interval (CI) = 0.72-0.87) and 0.75 (95% CI = 0.67-0.82), respectively. Additionally, the pooled area under the curve (AUC) was calculated as 0.84 (95% CI = 0.81-0.87), suggesting a moderate to good accuracy of the diagnostic test. Using Fagan's nomogram plot, the positive likelihood ratio (LR) and negative LR were found to be 3 and 0.26, respectively. The results demonstrated that the perfusion index exhibited an acceptable level of accuracy in predicting perioperative hypotension after spinal anesthesia in parturients undergoing elective CS. These findings highlight the potential value of incorporating a perfusion index as a useful tool for clinicians to integrate into routine clinical practice, which necessitates further large-scale studies for verification.

The transvaginal approach represents a suitable choice for the management of isthmocele in women seeking to become pregnant.

Antenatal steroid as an independent risk factor for vitamin K2 deficiency in newborns: A Chinese single-center, retrospective study

OBJECTIVES

To identified vitamin K2 deficiency rate and risk factors among newborns in China and assess the importance of high-risk maternal intakes of vitamin K2.

METHODS

This retrospective study was performed at the Neonatology Department, the Affiliated Hospital of Guangdong Medical University, China. Routinely collected mother-neonate hospitalization data from July 2020 to January 2021 were analyzed. In total, data from 200 neonates who had completed vitamin K2 tests were utilized to assess the prevalence of vitamin K2 deficiency and identify the potential risk factors. According to the vitamin K2 level, the neonates were divided into 2 groups: cases (vitamin K2 deficiency) and controls (no vitamin K2 deficiency). The potential risk factors for vitamin K2 deficiency were evaluated by univariate and multivariate logistic regression.

RESULTS

The vitamin K2 level in 24 of the 200 neonates was undetectable (<0.05 ng/mL). The prevalence of low serum vitamin K2 (<0.1 ng/ml) was 33%. Study subjects with antenatal corticosteroids use had an approximately 5-fold greater risk of developing vitamin K2 deficiency. In the univariate analyses, small-for-gestational-age (SGA), caesarean section, maternal gestational diabetes and premature rupture of the membranes were risk factors for vitamin K2 deficiency. In the multivariate logistic regression analysis, high antenatal corticosteroids use, cesarean section, and SGA were independently associated with vitamin K2 deficiency.

CONCLUSION

The present study demonstrated that antenatal corticosteroids use is independently associated with vitamin K2 deficiency. This finding highlights the importance of routine vitamin K2 supplementation in late-stage pregnant women and neonates in China.

Analysis of Cesarean Section Rates in a Public Tertiary Hospital During Teaching and Non-teaching Periods Using the Robson Ten Group Classification System

INTRODUCTION

The rising cesarean section (CS) rate is a global concern. One of the hospital characteristics that may explain the variation in CS among hospitals is hospital teaching status. This study aims to assess the rate of CS in a tertiary hospital during the teaching and non-teaching periods and to conduct an analysis using the Robson ten-group classification system.

METHODS

This study is a retrospective cohort that assessed pregnant mothers who gave birth at a tertiary hospital in Bandar Abbas. The study population was divided into two groups: those who gave birth during the hospital's teaching period (November 1st, 2019 to October 30th, 2020) and those who gave birth after that (November 1st, 2020 to October 30th, 2021). The primary outcome was the rate of CS according to Robson's classification system. The secondary outcome was the contributions of each group of Robson to the overall CS rate. Data were extracted by trained collectors from the "Iranian Maternal and Neonatal Network (IMaN Net)," a valid national system, using electronic patient records.

RESULTS

Of the total number of births (8382), 62.9 % occurred during the teaching period and 37.1 % during the non-teaching period. A 7% increase in CS was observed during the teaching period of the hospital compared to the non-teaching period (p<0.01). CS rate in Robson groups 1,2,4,7, and 10 differs significantly between teaching and non-teaching periods. According to the findings, Groups 5, 10, and 2 were the three most significant contributors to overall CS in our hospital during the study period.

CONCLUSION

The efforts to reduce the overall CS rate should be focused on groups 2,5, and 10 of Robson.

Epidural Anesthesia for Cesarean Section in a Pregnant Woman With Acute Pulmonary Edema: A Case Report

Although rare, acute pulmonary edema is the most common cause of death in pregnant women with severe hypertension. The authors report a case involving a pregnant woman at 36 weeks of gestation with preeclampsia, who exhibited pulmonary edema and required immediate cesarean delivery. The patient had type 1 respiratory failure and needed supplemental oxygenation with a Venturi mask. The cesarean section was performed successfully under epidural anesthesia. Women with severe preeclampsia and acute pulmonary edema remain a challenge when presented for cesarean delivery, and the best anesthetic option remains controversial.

Preoperative Oral Carbohydrate (CHO) Supplementation Is Beneficial for Clinical and Biochemical Outcomes in Patients Undergoing Elective Cesarean Delivery under Spinal Anaesthesia-A Randomized Controlled Trial

BACKGROUND

Preoperative fasting and surgery cause metabolic stress, insulin resistance with ketosis, and postoperative nausea and vomiting (PONV). Oral carbohydrate loading strategy (CHO) improves outcomes in labor and general surgery. We aimed to compare the effectiveness of CHO with standard fasting in patients undergoing elective cesarean delivery (CD) under spinal anesthesia.

METHODS

A single-center, parallel, prospective randomized controlled trial (RCT) was conducted in a tertiary university obstetrics department at Pomeranian Medical University in Szczecin, Poland. Patients were randomly assigned (1:1 ratio) to the CHO group (oral carbohydrate 2 h before elective CD, n = 75) or the SF group (control-standard fasting, n = 73). The main outcome measures were incidence and severity of PONV at 6 and 24 h after CD, time to the first peristalsis, time to first bowel movement, and biochemical parameters indicating ketosis in mothers and their children.

RESULTS

A total of 148 adult females with singleton pregnancies undergoing elective CD under spinal anesthesia (ASA I and II) were included in the final analysis. At 24 h after CD, 8.0% from the CHO group vs. 20.55% reported three or more episodes of vomiting or dry retching as compared to patients in the SF group (p = 0.041). Preoperative CHO supplementation decreased preoperative feelings of hunger (p < 0.001) and thirst (p < 0.001). Laboratory results in the CHO group showed higher plasma pH (p = 0.001) and glucose (p < 0.001), lower F2-isoprostane in plasma (p = 0.049) and urine (p = 0.018), lower urine F2-isoprostane/creatinine ratio (p = 0.045) than in the SF group. HOMA-IR (p < 0.001) and lactate (p < 0.001) were higher in the CHO group than in the control group.

CONCLUSIONS

There was no significant difference in the incidence or severity of early PONV at 6 h. The incidence of vomiting or dry retching at 24 h after cesarean delivery was lower in the CHO group as compared to standard starvation, but the combined results of PONV frequency and severity on the Wengritzky scale did not differ between the two study groups. Preoperative CHO supplementation decreased preoperative feelings of hunger and thirst, enhancing the comfort of pregnant women.

Risk of Cesarean Delivery after Vaginal Inserts with Prostaglandin Analogs and Single-Balloon Catheter Used for Cervical Ripening and Induction of Labor

(1) Background: Induction of labor is currently the most frequently performed procedure in modern obstetrics, referring to more than one in five women, and it is postulated that the percentage of labor induction will increase. (2) Methods: In total, 2935 patients in uncomplicated full-term pregnancy fulfilled the study inclusion criteria and underwent induction of labor. Pregnant women were divided into three groups: IOL with Dinoprostone, Misoprostol vaginal suppositories, and Foley catheter. Outcomes, including cesarean section rates, time to delivery, and cesarean section indications, were analyzed. (3) Results: There was statistically significantly more cesarean sections within 24 h in the Misoprostol group in comparison with the Dinoprostone and Foley catheter groups (p < 0.0001). The percentage of patients who had a cesarean section due to clinically diagnosed threatened fetal asphyxia was 63% in the Dinoprostone group, 81.3% in the Misoprostol group, and 55.3% in the Foley catheter group. There were statistically significantly more cesarean deliveries due to nonreassuring fetal heart rate patterns within 24 h in the Misoprostol group in comparison with the Dinoprostone and Foley catheter groups (p = 0.0031 and p = 0.0363). (4) Conclusions: Misoprostol may cause a more turbulent and violent course of labor, with a higher rate of increased incidence of nonreassuring fetal heart rate patterns and cesarean deliveries. The use of a Dinoprostone vaginal insert or Foley catheter may provide longer labor, although still within 48 h, with a lower risk of cesarean section caused by nonreassuring fetal heart rate patterns.

Vaginal birth after cesarean section: A quantitative study exploring women's understanding and experience regarding VBAC rates in Greece

INTRODUCTION

Vaginal birth after cesarean section (VBAC) is a choice of birth that provides many advantages for women. This study presents women's VBAC experience in a Greek population. The study's aims were mainly to determine the reasons for choosing VBAC, women's feelings during pregnancy and their experience, and level of post-birth satisfaction.

METHODS

This study is sampling research which has a cross-section retrospect study design. The study was held via the internet due to a self-administered questionnaire which is comprises both open-ended and close-ended questions. Data analysis was performed in S.P.S.S. 20 and Microsoft Excel.

RESULTS

A total number of 473 women participated in this study. The findings showed that during pregnancy and childbirth over 50% of women felt very happy and satisfied, while 35% to 40% felt moderate or no fear at all. Furthermore, 96.48% of them would attempt for a VBAC birth again while 97.36% would recommend this way of delivery to other women. There was a total of 78.85% of succeeded VBAC. The main reason for women to choose VBAC for a birth option were the desire for a normal birth (23.1%), the thought of vaginal birth as the normal way of giving birth (22.4%), to avoid another surgery (14.2%) and to experience a vaginal birth (10%).

CONCLUSIONS

VBAC is an option that needs to be offered more in Greece, and needs improvement in obtaining informed consent in obstetric care services. More studies are required to draw further conclusions.

The 300 versus 300 Study-Low Volume versus High Volume Single Balloon Catheter for Induction of Labor: A Retrospective Case-Control Study

The use of a Foley catheter is one of the oldest known methods of labor induction. Therefore, protocols using different volumes of Foley catheter balloons have been developed and tested to accurately determine their effectiveness. In this study, it was decided to retrospectively evaluate two induction of labor (IOL) protocols. The last 300 eligible patients who met the criteria and underwent the low-volume balloon protocol (40-60 mL) IOL were selected. Then next, 300 patients who met the criteria and underwent high-volume balloon (80-100 mL) IOL were selected. Outcomes included time to delivery and parturition type, oxytocin augmentation, operative deliveries and application of intrapartum anesthesia. Overall, the majority of patients delivered within 24 h. Patients who received a high-volume Foley catheter had statistically significantly more vaginal deliveries. The mean-time to delivery in the high-volume catheter group was statistically significantly shorter than in the low-volume catheter group. Patients who received a high-volume Foley catheter required statistically significantly less oxytocin augmentation during induction of labor compared to patients with a low-volume Foley catheter. Regardless of the balloon volume used, the percentage of operative deliveries remained at a similar, low level (8.36% and 2.14%). Regardless of the catheter volume used, the majority of patients chose epidural over intravenous anesthesia. In conclusion, a high-volume balloon Foley catheter IOL is characterized by an increased percentage of vaginal deliveries, shortened time to delivery regardless of the type of delivery, and lower need for oxytocin augmentation.

Supreme laryngeal mask airway for cesarean section under general anesthesia: a 10-year retrospective cohort study

Background

Previous research showed the use of supraglottic airways in obstetric anesthesia. The relevant evidence of laryngeal mask airway (LMA) on maternal and neonatal outcomes is still limited. We aimed to assess the maternal and neonatal outcomes when the LMA Supreme was used for cesarean section under general anesthesia.

Methods

We included all patients who underwent general anesthesia for cesarean section between January 2010 and December 2019. Propensity score matching was used to reduce potential bias from non-random selection of airway intervention. The primary outcome was adverse maternal and neonatal outcomes defined as maternal regurgitation, aspiration, hypoxemia, and low neonatal Apgar scores. Secondary outcomes included patient admission to the intensive care unit, neonate required tracheal intubation, external cardiac massage, and admission to the neonatal intensive care unit.

Results

A total of 723 patients were included in the analysis; of whom, 221 received Supreme laryngeal mask airway (LMA group) and 502 were intubated with an endotracheal tube (ETT group). After propensity score matching, 189 patients remained in each group. No episode of regurgitation and aspiration occurred in both groups. There was no difference in the rates of Apgar score below 7 at 1 min (14.3% LMA group vs. 15.3% ETT group, OR 0.931, 95% CI 0.574 to 1.510, P = 0.772) and 5 min (3.7% vs. 4.2%, OR 0.875, 95% CI 0.324 to 2.365, P = 0.792). No difference was observed in the secondary outcomes between the two groups.

Conclusion

The LMA Supreme was not associated with higher adverse maternal and neonatal outcomes when compared to an endotracheal tube for cesarean section under general anesthesia. It might be considered an alternative to tracheal intubation in obstetric practice.

Comparison of Dural Puncture Epidural, Epidural and Combined Spinal-Epidural Anesthesia for Cesarean Delivery: A Randomized Controlled Trial

Purpose

Catheter-based techniques such as combined spinal-epidural (CSE) anesthesia which are sometimes indicated for obstetric anesthesia have a complex mechanism of action. The application of the dural puncture epidural (DPE) anesthesia for cesarean section (CS) has not been well investigated. The present study compared the relatively novel DPE technique with epidural (EA) and CSE anesthesia.

Patients and Methods

We randomly assigned 150 parturients who underwent elective CS to receive DPE, EA or CSE anesthesia. The primary outcome was the onset of sensory anesthesia to the T5 dermatome assessed using the Cox proportional hazards model. Secondary outcomes included median time to sensory block, quality of block, patient and surgeon satisfaction, APGAR scores and other side effects.

Results

For DPE anesthesia versus EA anesthesia, the onset of anesthesia was faster (hazard ratio 2.47 [95% CI 1.56 to 3.90], adjusted P < 0.001) and the median time to surgical level was shorter (16 [IQR 14-18] min versus 19 [15.5-21] min, adjusted P < 0.001); the incidence of intraoperative pain was lower (7/48 versus 17/47, adjusted P = 0.046) and the median patient satisfaction score was higher (9 [IQR 9-10] versus 8 [8-9.5], adjusted P = 0.004). In the CSE group, the onset of anesthesia was faster than in the other two but the incidence of hypotension was higher (P < 0.001) and the phenylephrine requirement was greater (P < 0.001).

Conclusion

DPE anesthesia had a faster onset and better quality of block than EA anesthesia and provided less influence to maternal hemodynamic parameters than CSE anesthesia for CS. These results suggest that the dural puncture plays a significant role in enhancing the effectiveness of epidural top-ups during CSE anesthesia and indicates enlightenment that contributes to the satisfaction of anesthetic effect in DPE technique labor analgesia transferred to CS.

Trend of pregnancy outcomes in type 1 diabetes compared to control women: a register-based analysis in 1996-2018

Introduction

In 1989, the St Vincent declaration aimed to approximate pregnancy outcomes of diabetes to that of healthy pregnancies. We aimed to compare frequency and trends of outcomes of pregnancies affected by type 1 diabetes and controls in 1996-2018.

Methods

We used anonymized records of a mandatory nation-wide registry of all deliveries between gestational weeks 24 and 42 in Hungary. We included all singleton births (4,091 type 1 diabetes, 1,879,183 controls) between 1996 and 2018. We compared frequency and trends of pregnancy outcomes between type 1 diabetes and control pregnancies using hierarchical Poisson regression.

Results

The frequency of stillbirth, perinatal mortality, large for gestational age, caesarean section, admission to neonatal intensive care unit (NICU), and low Appearance, Pulse, Grimace, Activity, and Respiration (APGAR) score was 2-4 times higher in type 1 diabetes compared to controls, while the risk of congenital malformations was increased by 51% and SGA was decreased by 42% (all p<0.05). These observations remained significant after adjustment for confounders except for low APGAR scores. We found decreasing rate ratios comparing cases and controls over time for caesarean sections, low APGAR scores (p<0.05), and for NICU admissions (p=0.052) in adjusted models. The difference between cases and controls became non-significant after 2009. No linear trends were observed for the other outcomes.

Conclusions

Although we found that the rates of SGA, NICU care, and low APGAR score improved in pregnancies complicated by type 1 diabetes, the target of the St Vincent Declaration was only achieved for the occurrence of low APGAR scores.

[Effects of auricular thumbtack needle on lactation function and TDP-43/Btn1A1/XDH pathway in primiparous women with cesarean section]

OBJECTIVE

To observe the effects of auricular thumbtack needle on breast feeding and lactation function in primiparous women with cesarean section, and to explore its mechanism of action from the perspective of lactation-related gene expression.

METHODS

One hundred cases of primiparous women with cesarean section were randomly divided into an observation group (50 cases, 3 cases dropped off) and a control group (50 cases, 2 cases were eliminated). The patients in the control group were treated with routine obstetric care. Based on the treatment of the control group, the patients in the observation group were treated with auricular thumbtack needle at Neifenmi (CO₁₈), Xiong (AH₁₀), Xiongzhui (AH₁₁), Shenmen (TF₄), and Jiaogan (AH_6a), etc., with one side of auricular point selected, only once for a total of 3 d. The lactation initiation time, lactation adequacy rate at postpartum 72 h, exclusive breastfeeding rate at postpartum 42 d, and breastfeeding score after treatment were compared between the two groups. Real-time quantitative PCR and Western blot method were used to detect the mRNA and protein expression levels of TDP-43, Btn1A1 and XDH.

RESULTS

After treatment, the lactation initiation time in the observation group was earlier than that in the control group (P<0.01), and breastfeeding score in the observation group was higher than that in the control group (P<0.01). The lactation adequacy rate at postpartum 72 h was 63.8% (30/47) in the observation group, which was higher than 41.7% (20/48) in the control group (P<0.05). The exclusive breastfeeding rate at postpartum 42 d was 72.3% (34/47) in the observation group, which was higher than 47.9% (23/48) in the control group (P<0.05). The mRNA and protein expression levels of TDP-43 and Btn1A1 in breast milk in the observation group were higher than those in the control group (P<0.01), while there was no statistically significant difference in mRNA and protein expression of XDH in breast milk between the two groups (P>0.05).

CONCLUSION

The auricular thumbtack needle in addition to routine care could promote lactation initiation, improve lactation adequacy rate and exclusive breastfeeding rate in primiparous women with cesarean section, and the action mechanism may be related to up-regulation of TDP-43 and Btn1A1 expression.

Effects of vaginal microbiota transfer on the neurodevelopment and microbiome of cesarean-born infants: A blinded randomized controlled trial

The microbiomes of cesarean-born infants differ from vaginally delivered infants and are associated with increased disease risks. Vaginal microbiota transfer (VMT) to newborns may reverse C-section-related microbiome disturbances. Here, we evaluated the effect of VMT by exposing newborns to maternal vaginal fluids and assessing neurodevelopment, as well as the fecal microbiota and metabolome. Sixty-eight cesarean-delivered infants were randomly assigned a VMT or saline gauze intervention immediately after delivery in a triple-blind manner (ChiCTR2000031326). Adverse events were not significantly different between the two groups. Infant neurodevelopment, as measured by the Ages and Stages Questionnaire (ASQ-3) score at 6 months, was significantly higher with VMT than saline. VMT significantly accelerated gut microbiota maturation and regulated levels of certain fecal metabolites and metabolic functions, including carbohydrate, energy, and amino acid metabolisms, within 42 days after birth. Overall, VMT is likely safe and may partially normalize neurodevelopment and the fecal microbiome in cesarean-delivered infants.

A Prospective Single-Center Brazilian Study Investigating the Efficacy and Safety of Prophylactic Phenylephrine Infusion for the Management of Hypotension During Cesarean Section Under Spinal Anesthesia

Background Maternal hypotension occurs in up to 80% of parturients during cesarean section (CS) under spinal anesthesia. Phenylephrine, a direct-acting α-1 agonist, has been widely recommended for the prevention of hypotension. We evaluated the efficacy and safety of phenylephrine infusion to prevent hypotension in obese and non-obese patients during cesarean section. Methods One hundred forty-one patients were included in this single-arm study. Patients received prophylactic phenylephrine infusion at a rate of 50 μg/min-1 immediately after spinal local anesthetic injection until delivery. Hypotension was defined as a systolic blood pressure <100 mmHg or <20% of baseline. The primary outcome was the incidence of hypotension. Results The incidence of hypotension was 17%. The median and interquartile range (IQR) of the number of hypotensive episodes was 0 (0-0). It was observed that 79.1% of the patients had hypotension in the first six minutes. Reactive hypertension and bradycardia occurred in 20.5 and 12.7% of the patients, respectively. In addition, there was a higher incidence of bradycardia in pregnant women with a body index mass of < 30 kg/m-2. Patients with baseline systolic blood pressure <120 mmHg had a threefold increased risk of hypotension. The incidence of nausea and vomiting was 13.4 and 2.8%, respectively. The incidence of an Apgar score <7 at the first minute was 2.8%, and no neonates presented an Apgar score <7 at the fifth minute. A pH of <7.2 occurred in 6.3% of the neonates. All neonates had no sequelae and were discharged together with their mothers. Conclusion The prophylactic infusion of phenylephrine 50 μg/min-1 is safe and demonstrates efficacy in reducing maternal hypotension providing adequate maternal hemodynamic stability during CS under spinal anesthesia.

Why do Mothers from Remote Rural Areas opt for Cesarean Delivery: An Observational Analytical Study from West Bengal, India

Background

The percentage of cesarean section (C-section) deliveries has doubled in the last two decades in India. Although C-section delivery is a life-saving intervention, multiple maternal and neonatal morbidities are often associated with this procedure, adversely affecting the quality of life of both the mother and child.

Material and Methods

This community-based cross-sectional study was conducted to assess the point of view of mothers who delivered from January 2020 to June 2021.

Results

The mean (standard deviation (SD)) age of the 866 study participants at delivery was 24.5 (4.8) years, and 60.2% were primigravidas. A total of 613 (70.8%; 95% CI: 67.8-73.8) C-sections were conducted, of which 65.9% (n = 404) were planned and 21.9% were done on maternal request. C-sections were significantly associated with private institutes (adjusted prevalence ratio (aPR) 1.90; 95% CI: 1.70-2.11), at-risk pregnancy (aPR 1.37; 95% CI: 1.26-1.49), and primigravida (aPR 1.16; 95% CI: 1.05-1.29). About 55.3%, 29.8%, and 14.9% of women considered vaginal delivery to be risky, painful, and inconvenient, respectively.

Conclusion

It is imperative to generate awareness regarding modes of delivery during antenatal care (ANC) so that mothers can make better-informed choices.

Prophylactic Fixed-Rate Phenylephrine Versus Norepinephrine Infusion in the Prevention of Post-spinal Anesthesia Hypotension During Cesarean Delivery

Background Maternal hypotension following spinal anesthesia can be actively countered by the use of vasopressors. Prophylactic infusion of vasopressors with a rescue bolus dosing was observed to be more effective for hemodynamic stability when compared to administering a bolus dose alone. Although phenylephrine is the recommended drug to treat spinal hypotension, many recent studies have focussed on the role of norepinephrine infusions during cesarean section. In this study, we compared prophylactic fixed-rate intravenous infusions of phenylephrine and norepinephrine during cesarean delivery under spinal anesthesia and the requirement of intraoperative provider-administered rescue bolus of phenylephrine needed to overcome post-spinal anesthesia hypotension. Methodology A total of 208 patients undergoing elective cesarean section under spinal anesthesia were randomly assigned to two groups (group P and group N). Group N included 104 patients who received norepinephrine infusion at a rate of 2.5 μg/minute (0.04 μg/kg/minute), and group P included 104 patients who received phenylephrine infusion at a rate of 50 μg/minute (0.8 μg/kg/minute) to treat spinal hypotension. The primary outcome of our study was to compare the reduction in the number and total dose of intraoperative provider-administered rescue bolus of phenylephrine needed to maintain systolic blood pressure. The secondary outcome of our study was to compare the neonatal outcome using umbilical venous blood gas sampling and Apgar score at one and five minutes. Results The total number of phenylephrine rescue bolus required to treat hypotension was significantly lower in group N (p = 0.0005) compared to group P. The neonatal outcome was similar between the two groups. Conclusions Prophylactic norepinephrine infusion when compared to prophylactic phenylephrine infusion is associated with a lesser requirement of rescue phenylephrine boluses.

Comparing the Effect of Phenylephrine Bolus and Phenylephrine Infusion for Maintaining Arterial Blood Pressure During Cesarean Delivery Under Spinal Anesthesia: A Randomized Prospective Study

INTRODUCTION

 Maternal hypotension is a common complication of spinal anesthesia in cesarean section and requires immediate intervention. Phenylephrine is most commonly used as a vasopressor agent for the treatment of hypotension due to subarachnoid block. Our aim was to compare the bolus dose of 50 µg of phenylephrine with a fixed infusion at 50 µg.min-1 of phenylephrine for maintaining arterial blood pressure during cesarean delivery.

MATERIALS AND METHOD

 This was a prospective, randomized comparative study. One hundred normotensive pregnant females aged 18-35 years, body mass index 18-29kg.m2, American Society of Anesthesiologists (ASA) physical status classification II scheduled to undergo cesarean section (elective/emergency) under spinal anesthesia were randomly divided into two groups of 50 each. Group PB received a bolus dose of phenylephrine 50 µg after they developed hypotension i.e., a decrease in systolic blood pressure (SBP) ≥ 20% from the baseline. Similarly, patients in Group PI were administered prophylactic infusion using a syringe pump of phenylephrine 50 µg.min-1, started just after the administration of subarachnoid block. The phenylephrine infusion was continued either till the delivery of the baby or when SBP rises >20% above the baseline. Parameters like blood pressure, heart rate, and peripheral oxygen saturation were recorded. After the delivery of the baby, the neonatal APGAR score was assessed at one minute and five minutes.

RESULTS

Demographic data were comparable in terms of demographic profile, duration of surgery, and ASA physical status classification between the groups. The heart rate was higher in Group PB compared to Group PI throughout the monitoring period (P<0.001). The fall in mean blood pressure was more in Group PB compared to Group PI till 18 minutes of surgery and was statistically significant (P<0.05). After 18 minutes of surgery, mean blood pressure stabilized and was comparable between the groups. Other variables like APGAR score at one minute and five minutes were comparable between the groups. Bradycardia and hypertension were more common in Group PI whereas hypotension, nausea, and vomiting were more common in group PB.

CONCLUSION

We concluded that during cesarean section under spinal anesthesia, phenylephrine infusion provides better hemodynamic stability and APGAR score during the perioperative period.

Analgesic efficacy of bupivacaine with or without magnesium adjunct in bilateral ilioinguinal and iliohypogastric nerve blocks following cesarean section under subarachnoid block: A randomized controlled trial

Background

Pain relief is a basic aspect of anesthesia care. Optimal post-cesarean section analgesia should minimize postoperative complications, facilitate infant care, and prevent postoperative morbidity. Bilateral ilioinguinal-iliohypogastric (IIIH) nerve block has been considered as a part of the multimodal approach. This study was designed to explore the efficacy of adding magnesium sulfate as an adjunct to bupivacaine to provide analgesia following cesarean delivery, using bilateral IIIH nerve block.

Materials And Methods

Seventy-two parturients who were scheduled for elective cesarean section were randomized into two groups of 36 patients each. Group MB patients were given bilateral IIIH nerve block with 250 mg of magnesium sulfate and 95 mg of 0.25% plain bupivacaine. Group B patients were given bilateral IIIH nerve block with 0.9% normal saline and 95 mg of 0.25% plain bupivacaine. Postoperative visual analog scale (VAS) pain scores at post-anesthesia care unit (PACU), 2, 4, 6, 12, and 24 h, both at rest and with activity were measured. Rescue doses of opioid (intravenous [IV] tramadol 50 mg) at each time point of assessment, total tramadol consumption, time to patients' first request for rescue analgesic agent, and patients' satisfaction score were recorded.

Results

The demographic and social parameters of patients in both the groups were comparable. The mean postoperative VAS pain score in group MB was significantly lesser both at rest and with movement than in group B at 12 and 24 h after surgery (P < 0.05). Total postoperative tramadol consumed over 24 h was significantly lesser in the magnesium group than in the control group (125.55 ± 20.76 vs. 160.24 ± 25.82 mg), with a P value of 0.026. The time to patient's first analgesic request was significantly prolonged in group MB compared to group B (505.2 ± 41.4 vs. 372.6 ± 88.8 min, respectively), with a P value of 0.040. However, patients in both groups expressed good satisfaction scores.

Conclusion

Magnesium sulfate as an adjunct to bupivacaine in bilateral IIIH nerve block reduced VAS pain scores, total tramadol consumption, and prolonged post-cesarean section analgesia.

Can Stria Gravidarum Predict Surgical Fluid Loss in Cesarean Section?

INTRODUCTION

Alterations in collagen subtypes and matrix can potentially cause fluid loss in surgery which is important in terms of liquid loss.

OBJECTIVES

The study aimed to analyze stria gravidarum (SG) and its severity in pregnant women who had undergone cesarean section (CS) and to evaluate surgical fluid loss (SFL) that occurred during CS operation.

METHODS

The research was designed as a prospective clinical cohort study to compare the amount of SFL in the second cesarean section with the severity of SG at 34-37 weeks pregnant (N 308). The severity of SG was evaluated in the preoperative period using the Davey scoring. All patients were defined none, mild stria and severe stria. The SFL was calculated by weighing the pre-and post-operative weights of the sponges.

RESULTS

The weight gain (P = 0.008) and body mass index (BMI, P = 0.017) gradually increased toward severe SG. In correlation analysis of SFL, a positive correlation was found with Davey (r=0.791; P = 0.0001), weight gained during pregnancy (r=0.328; P = 0.0001), BMI (r=0.453; P = 0.001) and newborn weight (r=0.139; P = 0.003). In the receiver operating characteristic for the predictability of SG severity on SFL, severe SG showed a potential for SFL with 95.1% specificity and 93.2% sensitivity at 791 cut-offs (area under the curve:0.987; P = 0.00001; 95% confidence interval: 0.977-0.997).

CONCLUSIONS

The SG severity and SFL showed a very strong relationship, which was a very important finding that would affect the approach of the surgeons to the patients with SG in terms of fluid loss in CS.

Risk factors associated with cesarean section and adverse fetal outcomes in intrahepatic cholestasis of pregnancy

Background

To determine the risk factors for cesarean section (CS) and adverse fetal outcomes (AFOs) in patients with intrahepatic cholestasis of pregnancy (ICP) based on the severity of maternal hypercholanemia.

Methods

A hospital-based retrospective cohort study was performed between January 1, 2015, and December 31, 2019. A total of 227 nulliparous women with a singleton fetus complicated by ICP were included. The patients were divided into two groups according to the levels of total bile acids, that is, mild (10 μmol/L < total bile acids < 40 μmol/L) and severe (≥40 μmol/L). The patients' clinical characteristics and fetal outcomes were assessed.

Results

Among the 227 eligible women, 177 (78.0%) were allocated to the mild group and 50 (22.0%) were in the severe group. Women with severe ICP also had a significantly higher incidence of planned and unplanned CS compared with mild ICP subjects (52.0% vs. 23.7% and 22.0% vs. 6.8%, respectively; p < 0.001). The indications for CS showed that fetal intolerance (65.4% vs. 14.3%) was higher in severe ICP compared with mild ICP (p < 0.001). Severe ICP was associated with an increased risk of preterm delivery (p < 0.001), low birthweight (p = 0.001), and neonatal intensive care unit (NICU) admission (p < 0.001). Women with severe ICP (OR 6.397, 95%CI 3.041-13.455, p < 0.001) or preeclampsia (OR 12.434, 95%CI 5.166-29.928, p < 0.001) had increased risks of AFOs compared to controls.

Conclusions

Severe ICP and preeclampsia are associated with a higher incidence of AFOs.

The Relation between Neonatal Intensive Care Units and Postpartum Post-Traumatic Stress Disorder after Cesarean Section

BACKGROUND

The experience of a neonate hospitalized in the NICU is an understandably traumatic experience for parents, especially for the mothers of neonates. This mental distress resulting from preterm birth and/or NICU hospitalization can be understood as post-traumatic symptomatology, according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-5 version). The aim of this study is to investigate the impact of the admission of a neonate to the NICU (forany reason) on the development of postpartum PTSD in a sample of women after cesarean section.

METHODS

A total of 469 women who gave birth with cesarean section from July 2019 to June 2020 participated in this study out of the original sample of 490 women who consented to participate. Data were obtained from the researcher's socio-demographic questionnaire and the post-traumatic stress checklist (PCL-5) from the Diagnostic and Statistical Manual of Mental Disorders DCM-5 version.

RESULTS

In total,11.7% of the sample experienced postpartum PTSD. There is a strong relationship between the inclusion of a neonate to the NICU due to perinatal stress, breathing difficulties, infections, and IUGR with postpartum PTSD (37.7%) in relation to the perinatal stress Criterion A (fear for the life of the neonate), the first criterion of postpartum PTSD.

CONCLUSIONS

Additional measures must be taken for mothers of children who have been admitted to the neonatal intensive care unit with psychological support interventions and a reassessment of their mental state.

Mirroring Perinatal Outcomes in a Romanian Adolescent Cohort of Pregnant Women from 2015 to 2021

Although the rates of adolescent pregnancies appear to have dropped according to the World Health Organization (WHO), the decrease in the age of the first menarche and better nutrition seems to contribute to the otherwise high rate of adolescent pregnancy worldwide, despite the efforts of different organizations to improve upon this trend. We conducted a population-based retrospective cohort study from January 2015 to December 2021 using our hospitals' database. We totaled 2.954 adolescent and 6.802 adult pregnancies. First, we compared younger adolescents' outcomes with those of older adolescents, as well as with adolescents aged between 18 and 19 years old; secondly, we compared adolescent pregnancies with adult ones. We detected higher percentages of cephalo-pelvic disproportion (43.2%), cervical dystocia (20.7%), and twin pregnancy (2.7%) in underage adolescents compared with 32%, 14.1%, and 1% in older underage adolescents, respectively, and 15.3%, 3.1%, and 0.6% in older ones. As teens became older, the likelihood of malpresentations and previous C-sections rose, whereas the likelihood of vaginal lacerations declined. When comparing adolescents with adult women, we found more cases that required episiotomy (48.1% compared with 34.6%), instrumental delivery (2.1% compared with 1%), and cervical laceration (10.7% compared with 8.4%) in the adolescent group, but the rates of malpresentation (11.4% compared with 13.5%), previous C-section (13.9% compared with 17.7%), and placenta and vasa praevia (4.5.6% compared with 14%) were higher in the adult women group. Adolescent pregnancy is prone to being associated with higher risks and complications and continues to represent a challenge for our medical system.

Content Quality of YouTube Videos About Pain Management After Cesarean Birth: Content Analysis

BACKGROUND

YouTube is an increasingly common source of health information; however, the reliability and quality of the information are inadequately understood. Several studies have evaluated YouTube as a resource during pregnancy and found the available information to be of poor quality. Given the increasing attention to postpartum health and the importance of promoting safe opioid use after birth, YouTube may be a source of information for birthing individuals. However, little is known about the available information on YouTube regarding postpartum pain.

OBJECTIVE

The purpose of this study is to systematically evaluate the quality of YouTube videos as an educational resource for postpartum cesarean pain management.

METHODS

A systematic search of YouTube videos was conducted on June 25, 2021, using 36 postpartum cesarean pain management-related keywords, which were identified by clinical experts. The search replicated a default YouTube search via a public account. The first 60 results from each keyword search were reviewed, and unique videos were analyzed. An overall content score was developed based on prior literature and expert opinion to evaluate the video's relevance and comprehensiveness. The DISCERN instrument, a validated metric to assess consumer health information, was used to evaluate the reliability of video information. Videos with an overall content score of ≥5 and a DISCERN score of ≥39 were classified as high-quality health education resources. Descriptive analysis and intergroup comparisons by video source and quality were conducted.

RESULTS

Of 73 unique videos, video sources included medical videos (n=36, 49%), followed by personal video blogs (vlogs; n=32, 44%), advertisements (n=3, 4%), and media (n=2, 3%). The average overall content score was 3.6 (SD 2.0) out of 9, and the average DISCERN score was 39.2 (SD 8.1) out of 75, indicating low comprehensiveness and fair information reliability, respectively. High-quality videos (n=22, 30%) most frequently addressed overall content regarding pain duration (22/22, 100%), pain types (20/22, 91%), return-to-activity instructions (19/22, 86%), and nonpharmacologic methods for pain control (19/22, 86%). There were differences in the overall content score (P=.02) by video source but not DISCERN score (P=.45). Personal vlogs had the highest overall content score at 4.0 (SD 2.1), followed by medical videos at 3.3 (SD 2.0). Longer video duration and a greater number of comments and likes were significantly correlated with the overall content score, whereas the number of video comments was inversely correlated with the DISCERN score.

CONCLUSIONS

Individuals seeking information from YouTube regarding postpartum cesarean pain management are likely to encounter videos that lack adequate comprehensiveness and reliability. Clinicians should counsel patients to exercise caution when using YouTube as a health information resource.

Cesarean section trends from 1992 to 2016 in Estonia and Finland: A registry-based study

INTRODUCTION

The number of cesarean sections (CSs) has grown steadily, but the underlying factors driving this increase remain unknown. Data from Medical Birth Registries were retrieved to analyze CS trends in Estonia and Finland during the period 1992-2016.

MATERIAL AND METHODS

All births in Estonia (n = 356 063) and Finland (n = 1 437 234) were included. The differences between Estonia and Finland in five-year time periods for the total CS rate, and rates in Robson 1, 2, and 5 groups (R1, R2, R5) were analyzed by logistic regression. Total CS rates were adjusted for birthweight, parity, previous CS, gestational age, singleton pregnancy, cephalic position, induction, mother's age. R1; R2; R5 rates were adjusted for birthweight and mother's age.

RESULTS

In Estonia, the proportion of CSs increased from 6.5% to 21.0% and in Finland from 15.1% to 16.8% between 1992 and 2016. In 2016, Estonia and Finland remained within the target value with their R1 + 2 (Estonia 18%; Finland 16%) and R5 (Estonia 59%; Finland 42%) values.

CONCLUSIONS

Comparing Robson groups in different countries can shed light on divergent CS rates and to improve the quality of perinatal and obstetric care.

The Experience of Women Giving Birth after Cesarean Section-A Longitudinal Observational Study

Natural childbirth after a previous cesarean section is a debated issue despite scientific research and international recommendations. This study aimed to examine the experiences of women giving birth after a previous cesarean section, their preferences, and changes in attitudes towards childbirth after labor. This longitudinal study involved 288 pregnant women who had a previous cesarean section and completed a web-based questionnaire before and after labor, including information about their obstetric history, birth beliefs, and preferred mode of delivery. Among women who preferred a vaginal birth, nearly 80% tried it and 49.78% finished delivery by this mode. Among women declaring a preference for an elective cesarean section, 30% attempted a vaginal birth. Choosing a hospital where staff supported their decision (regardless of the decision) was the most helpful factor in preparing for labor after a cesarean section (63.19%). Women's birth preferences changed after labor, with women who had a vaginal birth after a cesarean section preferring this mode of delivery in their next pregnancy (89.34%). The mode of birth did not always follow the women's preferences, with some women who preferred a natural childbirth undergoing an elective cesarean section for medical reasons. A variety of changes were noticeable among women giving birth after a cesarean section, with a large proportion preferring natural birth in their next pregnancy. Hospitals should support women's birth preferences after a cesarean section (if medically appropriate), providing comprehensive counseling, resources, and emotional support to ensure informed decisions and positive birth experiences.

Review of socioeconomic risk factors for cesarean births: a population-based study

OBJECTIVES

The reasons for increased cesarean section (CS) rates are complex and multifactorial. The goal of this study was to look at different social and economic factors that might be causing more cases of CS in the population.

STUDY DESIGN

A retrospective population-based cohort study. Data was taken from the Perinatal Neonatal Outcomes Research study in the Arabian Gulf (PEARL study) registry. Data from 60,728 live births ≥ 24 weeks of gestation were analyzed. In this study, various socioeconomic factors, such as maternal nationality, religion, educational level, employment status, parental income, consanguinity, housing, preterm birth, and tall stature, were examined for women undergoing cesarean section (CS) and their economic outcomes. Women who underwent vaginal delivery (VD) were compared. There are risks associated with pregnancy, smoking, assisted conception, and prenatal care.

RESULTS

60,728 births ≥ 24 weeks gestation were included in the analysis. 17,535 women delivered by CS (28.9%). Women with university-level -education and above were more likely to deliver by CS (61%), as compared to illiterate women or women with basic education at elementary or secondary levels (OR 0.73, CI 95%: P: <0.0001). Working women were more likely to deliver by CS (OR 1.40, CI 95%, P value <0.0001). Women living in rented houses were less likely to achieve a normal delivery (71.8%) (OR 1.40, CI 95%; P: <0.0001) as compared to women living in owned houses (74.7%). Women over 20 years old tended to achieve more VD compared to women less than 20 years old. P value <0.0001. Smoking was associated with lower chances of VD, with 42.4% of smokers delivered by CS compared to 28.3% of non-smokers (OR 1.87, CI 95%; P: <0.0001). Assisted conception was associated with higher CS rates as compared to spontaneous conceptions (OR 0.39; P: <0.0001). We found no statistically significant differences in how babies were born based on the mother's nationality, the father's job, or the mother's income.

CONCLUSIONS

Higher education, employed mothers, smoking, and living in rented houses were socioeconomic factors associated with a higher rate of CS in our population. Furthermore, women who had regular antenatal care were more at risk for delivery by cesarean section, which could be related to other comorbidities increasing the likelihood of cesarean birth rather than antenatal care itself. In our population, assisted reproduction was associated with a higher probability of cesarean delivery.

Effect of initial anesthetic technique on fetal cord blood gas pH for cesarean deliveries performed for the indication of fetal heart rate abnormalities

Background

We hypothesized that parturients who had general anesthesia as the initial anesthetic technique for cesarean deliveries performed for fetal heart rate abnormalities would have a lower fetal cord blood gas pH compared to parturients who had regional anesthesia as the initial anesthetic technique.

Methods

We searched our electronic medical record for patients who had cesarean deliveries for the indication of fetal heart rate abnormalities from July 1, 2019, to June 30, 2021, at our hospital. An obstetrics resident and a maternal fetal medicine physician determined if the fetal heart tracing was category 2 or 3.

Results

A total of 130 and 29 patients with category 2 and 3 fetal heart tracing had regional and general anesthesia as the initial anesthetic technique, respectively. Fourteen and 20 patients with a category 3 fetal heart tracing had regional and general anesthesia as the initial anesthetic techniques, respectively. There were no differences in fetal cord blood gas pH between patients who had regional or general anesthesia as the first attempted anesthetic technique when patients with category 2 and 3 tracings were evaluated separately.

Conclusion

The initial anesthetic technique attempted for cesarean delivery was not associated with a worse fetal cord blood gas pH.

The amenorrhea as a protective factor for healing of hysterotomy - a retrospective analysis one year postpartum

OBJECTIVES

The good healing of the hysterotomy after cesarean section is important for subsequent pregnancies. However, the factors which improve this healing have not been completely described, yet. In this study, we focused on factors which may affect healing of hysterotomy within one year after delivery, such as menstruation, breastfeeding, and the use of the contraception.

MATERIAL AND METHODS

Following delivery, total of 540 women were invited for three consecutive visits at six weeks, six months, and 12 months postpartum. The presence of menstruation, frequency of breastfeeding and contraception use were recorded. The scar was evaluated by vaginal ultrasound as already described. The impact of menstruation, breastfeeding, and contraception method on presence of niche was evaluated.

RESULTS

The presence of menstruation increased odds to have niche by 45% (CI 1.046-2.018, p = 0.026). Secondarily, our results demonstrated a statistically significant protective effect of breastfeeding on the incidence of niche with OR 0.703 (CI 0.517-0.955, p = 0.024). Breastfeeding decreases odds to have niche by 30%. Also, the use of gestagen contraception lowered the odds by 40% and intrauterine device (IUD) or combine oral contraceptive (COC) by 46.5%. The other possibly intervening factors were statistically controlled.

CONCLUSIONS

Amenorrhea, breast-feeding and progesterone-contraceptive decreases the risk of uterine niche within one year follow up.
