Perinatal mortality and its predictors in Beni City, Democratic Republic of Congo: a cross-sectional study.

BACKGROUND: Globally, perinatal mortality rates have decreased considerably in the last 30 years. However, in sub-Saharan African countries perinatal mortality remains a public health burden. Therefore, this study aimed to determine the Perinatal Mortality Rate and the factors associated with perinatal mortality in Beni City, Northeastern Democratic Republic of Congo. METHODS: A hospital-based retrospective cross-sectional study was conducted among 1394 deliveries that were documented in Beni General Referral Hospital from 2 January to May 31, 2022. The study was done in the conflict-ridden Beni city of the North Kivu Province. Analysis was done using Open Epi and SPSS version 22. Binary and Multivariate logistic regression analyses were performed. Odds ratio with 95% confidence interval was used to measure strength of association. RESULTS: Findings indicate that 60.7% of 1394 participants were below the age of 21 years, and 95.1% (1325) Beni residents. The Perinatal Mortality Rate was 42.3 per 1000 live births. Majority (51) of the postpartum women who experienced perinatal mortality didn`t have a history of perinatal mortality as compared to their counterparts. Multivariable analysis revealed that birth weight (AoR = 0.082, 95% CI 0.014-0.449, p < 0.05) and Apgar score in the 10th minute (AoR = 0.082, 95% CI 0.000- 0.043, p < 0.05) were significantly associated with Perinatal mortality. CONCLUSION: The high perinatal mortality rate in Beni General Referral Hospital, approximately four in every 100 births remains a disturbing public health concern of which is attributable to low birth weight and Apgar score. This study may help policy-makers and healthcare providers to design preventive interventions.

Comparison of Apgar scores and cord blood gas parameters in fetuses with isolated congenital heart disease and healthy controls.

OBJECTIVE: This retrospective study aimed to investigate how congenital heart disease (CHD) affects early neonatal outcomes by comparing Apgar scores and umbilical cord blood gas parameters between fetuses with structural cardiac anomalies and healthy controls. Additionally, within the CHD group, the study explored the relationship between these parameters and mortality within six months. METHODS: Data from 68 cases of prenatally diagnosed CHD were collected from electronic medical records, excluding cases with missing data or additional comorbidities. Only patients delivered by elective cesarean section, without any attempt at labor, were analyzed to avoid potential confounding factors. A control group of 147 healthy newborns was matched for delivery route, maternal age, and gestational week. Apgar scores at 1, 5, and 10 minutes, as well as umbilical cord blood pH, base deficit, and lactate levels, were recorded. RESULTS: Maternal age, gestational week at delivery, and birth weight were similar between the CHD and control groups. While Apgar score distribution was significantly lower at 1st, 5th, and 10th minutes in the CHD group, umbilical cord blood gas parameters did not show significant differences between groups. Within the CHD group, lower umbilical cord blood pH and larger base deficit were associated with mortality within six months. CONCLUSION: Newborns with CHD exhibit lower Apgar scores compared to healthy controls, suggesting potential early neonatal challenges. Furthermore, umbilical cord blood pH and base deficit may serve as predictors of mortality within six months in CHD cases. Prospective studies are warranted to validate these findings and integrate them into clinical practice, acknowledging the study's retrospective design and limitations.

Development of neonatal Apgar scoring training program utilizing contactless hand tracking in immersive virtual reality.

BACKGROUND: The rapid and accurate assessment of neonatal asphyxia is critical to preventing potentially fatal outcomes. Therefore, nursing students must acquire the skills to assess newborn conditions immediately after birth and implement appropriate interventions. Virtual reality (VR) simulation education has emerged as a promising tool for nursing education, offering repetitive and customizable clinical training while ensuring patient safety and overcoming spatiotemporal limitations. AIM: This study investigated the effects of a contactless hand-tracking-based immersive VR neonatal Apgar scoring program, adapted from experiential learning theory. DESIGN: A non-randomized controlled trial with a pre-post-test, quasi-experimental design was conducted. SETTINGS: The study was conducted at two nursing schools from July to October 2023. PARTICIPANTS: Participants comprised nursing students holding bachelor's degrees in nursing, with three or four years of experience and successful completion of a neonatal nursing theory course. Additionally, individuals with at least six months of experience working in a neonatal ward or delivery room before enrolling in nursing school were eligible. METHODS: The participants were divided into three groups: the VR group (n = 27) received contactless hand-tracking-based immersive VR neonatal Apgar scoring training; the simulation group (n = 28) received face-to-face Apgar scoring simulation training; and the control group (n = 26) received instruction on the Apgar scoring criteria. Changes in scores among the VR, simulation, and control groups were statistically compared using ANOVA with SPSS-WIN 27.0. RESULTS: The VR group exhibited significant improvements in knowledge, learning satisfaction, self-confidence, immersion, and motivation compared to the simulation and control groups. Moreover, satisfaction was significantly higher in the VR group than in the simulation group. CONCLUSIONS: The hand-tracking-based immersive VR neonatal Apgar scoring program represents an innovative and effective educational tool, prioritizing the privacy and rights of mothers and infants. It can potentially replace traditional delivery-room clinical training, which is observation-based and limited.

Virginia Apgar (1909-1974): The Mother of Neonatal Resuscitation.

Dr. Virginia Apgar was an American anesthesiologist and researcher who heavily influenced the development of neonatal resuscitation in the immediate postpartum period with her simple five-point scoring system. Today, the APGAR scoring system is used around the world in delivery rooms to guide clinicians in the evaluation of newborns and to distinguish which might need urgent resuscitation. With a simple scoring system, timer, and clipboard, Dr. Virginia Apgar shifted focus from the parturient to the neonate, improving infant mortality as a result.

Enoxaparin sodium combined with magnesium sulfate in the treatment of severe preeclampsia.

Objective: To observe the treatment of severe preeclampsia in newborns with enoxaparin sodium combined with magnesium sulfate. Methods: A retrospective analysis was conducted on the clinical data of 80 patients with severe preeclampsia admitted to Hefei Second People's Hospital, China from January 2019 to December 2020. Treatment records showed that 40 cases received magnesium sulfate treatment (single group), and 40 cases received enoxaparin sodium combined with magnesium sulfate treatment (combination group). Levels of D-dimer, soluble fms-like tyrosine kinase 1 (sFlt-1), placental growth factor (PLGF), Apgar scores of newborns delivered before and after treatment were compared. Gestation weeks and incidence of adverse reactions were analyzed. Results: After treatment, levels of D-dimer, sfit-1 and adverse reactions in the combination group were significantly lower than those in the single group (P<0.05), and the level of PLGF, newborn Apgar score and length of gestation were significantly higher than those in the single group (P<0.05). Conclusion: Compared to magnesium sulfate alone, the combination of enoxaparin sodium and magnesium sulfate in the treatment of pregnant women with severe preeclampsia can more effectively regulate the cytokine level of patients, improve pregnancy outcome, and improve neonatal Apgar score. The incidence of adverse reactions is low, making it a safe and efficient treatment modality.

Maternal and perinatal health indicators in Brazil over a decade: assessing the impact of the COVID-19 pandemic and SARS-CoV-2 vaccination through interrupted time series analysis.

Background: Few studies have evaluated the effects of the Coronavirus disease 2019 (COVID-19) pandemic, caused by the SARS-CoV-2 virus, on maternal and perinatal health at a populational level. We investigated maternal and perinatal health indicators in Brazil, focusing on the effects of the COVID-19 pandemic, and SARS-CoV-2 vaccination campaign for pregnant women. Methods: Utilizing interrupted time series analysis (January 2013-December 2022), we examined Maternal Mortality Ratio, Perinatal Mortality Rate, Preterm Birth Rate, Cesarean Section Rate, and other five indicators. Interruptions occurred at the pandemic's onset (March 2020) and pregnant women's vaccination (July 2021). Results were expressed as percent changes on time series' level and slope. Findings: The COVID-19 onset led to immediate spikes in Maternal Mortality Ratio (33.37%) and Perinatal Mortality Rate (3.20%) (p < 0.05). From March 2020 to December 2022, Cesarean Section and Preterm Birth Rates exhibited upward trends, growing monthly at 0.13% and 0.23%, respectively (p < 0.05). Post start of SARS-CoV-2 vaccination (July 2021), Maternal Mortality Ratio (-34.10%) and Cesarean Section Rate (-1.87%) promptly declined (p < 0.05). Subsequently, we observed a monthly decrease of Maternal Mortality Ratio (-9.43%) and increase of Cesarean Section Rate (0.25%) (p < 0.05), while Perinatal Mortality Rate and Preterm Birth Rate showed a stationary pattern. Interpretation: The pandemic worsened all analyzed health indicators. Despite improvements in Maternal Mortality Ratio, following the SARS-CoV-2 vaccination campaign for pregnant women, the other indicators continued to sustain altered patterns from the pre-pandemic period. Funding: No funding.

Association of maternal serum vitamin D level with fetal pulmonary artery Doppler indices and neonatal respiratory distress syndrome.

PURPOSE: Respiratory distress syndrome (RDS) is potentially fatal in infants. The present study investigated the association of maternal serum vitamin D level with fetal pulmonary artery Doppler indices and neonatal RDS. METHODS: This cross-sectional-analytical study was conducted on 260 mothers admitted for delivery. The maternal serum 25-hydroxyvitamin D level was measured and fetal main pulmonary artery Doppler indices were evaluated. The neonate's weight, apgar score, RDS, Umbilical cord arterial pH and neonatal intensive care unit admission were recorded. RESULTS: There was a significant relationship between RDS and the low level of vitamin D in the mother's serum. Mothers with low vitamin D had higher fetal pulmonary artery pulsatility index (PI) and peak systolic velocity (PSV) and lower acceleration time (AT) to ejection time (ET) ratio. Also, in neonates with RDS, pulmonary artery PI was higher, and PSV and the ratio of AT to ET were significantly lower than neonates without RDS. Neonates with lower one and 5-min apgar scores were born from mothers with lower vitamin D levels. CONCLUSION: Serum levels of vitamin D in pregnant mothers as well as fetal pulmonary artery Doppler indices are correlated to RDS. There is a significant relationship between the serum level of vitamin D in pregnant mothers and fetal pulmonary artery Doppler indices.

Fetal Clinical and Paraclinical Outcomes in HIV-Positive Pregnant Women.

Background Adverse pregnancy outcomes in women with human immunodeficiency virus (HIV) infection remain significantly increased. Untreated maternal infection primarily leads to fetal complications, such as intrauterine growth restriction, stillbirth, or preterm birth. Concerning both maternal and fetal complications that can appear in pregnancy associated with HIV infection, the purpose of the study was to determine fetal and maternal demographic characteristics and the correlation between blood count parameters and poor fetal prognosis. Methods We conducted a quantitative study utilizing document review as the data collection method. This study encompassed a cohort of nine HIV-positive pregnant women who delivered at the Obstetrics and Gynecology Department of the University Emergency Hospital in Bucharest from January 1, 2021, to December 31, 2023. A comparative cohort of nine healthy pregnant women who delivered during the same period in the same facility was selected using stratified random sampling. We examined maternal and fetal demographic parameters and neonatal outcomes, reporting them to paraclinical laboratory data. Results The incidence of pregnancy-related HIV infections was 0.16%. The mean age of patients in the selected group was 29.88 ± 5.53. There was no statistically significant correlation between maternal clinical and paraclinical parameters in the HIV-positive and HIV-negative groups. Although there was a slightly negative difference in the fetal weight at birth, the 1-min APGAR (appearance, pulse, grimace, activity, and respiration) score, and the intrauterine growth restriction between the two groups, there was a statistically significant association between admission to the neonatal intensive care unit (NICU) and the neonates from HIV-positive pregnancies. In our study, we observed preterm deliveries in 22.22% of cases, and we did not record any stillbirths. The 1-min APGAR score was correlated with the value of leukocytes in peripheral blood. Vertical transmission was established to be 11.11% independent of maternal blood count parameters. Conclusion HIV infection during pregnancy leads to a higher risk of admission to the NICU. Fetal leukocytosis is indicative of a lower 1-min APGAR score. The primary emphasis of therapeutic intervention during pregnancy should center on vigilant monitoring of maternal viral load and the timely administration of antiretroviral therapy to enhance fetal outcomes.

Nine is the New Ten of Apgar Scores: An Observational Retrospective Cohort Study.

Apgar scores of 10 were once common but are now rare. We aggregated scores from US term infants from 1978 to 2021. We found that scores of 10 decreased by logarithmic decay independent of demographic changes. We hypothesize that this trend was driven by improved appreciation of transitional physiology.

SARS-CoV-2 Infection in Pregnant Women With Hypothyroidism.

Background Severe acute respiratory syndrome coronavirus 2 (SARS­CoV­2) infection has been linked to increased maternal and fetal morbidity and mortality, as evidenced by numerous studies. Given the potential exacerbation of autoimmune diseases during viral infections, maternal and fetal complications such as preterm birth, low birth weight, or preeclampsia, often observed in pregnancies involving autoimmune thyroiditis with hypothyroidism, may be further aggravated. This study seeks to ascertain whether the association between viral infection and hypothyroidism contributes to an increase in adverse pregnancy outcomes. Methods This study included a cohort of 145 pregnant women with SARS-CoV-2 infection, who delivered in the Department of Obstetrics and Gynecology of the University Emergency Hospital in Bucharest, Romania, between January 1, 2020, and December 31, 2022. The participants were divided into two groups depending on the presence of autoimmune thyroiditis with hypothyroidism. We examined the maternal and fetal demographic parameters, paraclinical laboratory parameters, and outcomes, aiming to identify disparities between the two groups. Results Among the 145 SARS-CoV-2-positive pregnant women, the prevalence of hypothyroidism was 8.96%, with 13 cases reported. In the hypothyroidism group, the mean age of coronavirus disease 2019 (COVID-19) patients was higher (34.07 ± 5.18 years vs. 29.25 ± 6.23 years), as was the number of cases of investigated pregnancies, 12 (92.31%) vs. 91 (68.94%). There was no statistically significant correlation observed between fetal weight at birth, one-minute Apgar score, neonatal intensive care unit (NICU) admission, or intrauterine growth restriction between the two groups. Nevertheless, a case of stillbirth was recorded in the hypothyroidism group. The presence of thyroid pathology did not exacerbate the progression of the viral infection, as evidenced by the absence of cases of preeclampsia, ICU admission, or SARS-CoV-2 pneumonia. Conversely, the presence of hypothyroidism in pregnant women with SARS-CoV-2 infection was associated with lower uric acid levels and a slight decrease in international normalised ratio (INR) values. Additionally, there was a significant negative association between uric acid levels and the one-minute Apgar score in the hypothyroidism group, while no such correlations were observed in the other group. Furthermore, there was a statistically significant correlation between intrauterine growth restriction and uric acid values, as well as between the one-minute Apgar score and INR parameters, in both groups. Conclusion The link between SARS-CoV-2 infection and hypothyroidism does not appear to increase the risk of preterm birth, intrauterine growth restriction, or low fetal weight at birth. However, it may be associated with a higher risk of stillbirth. The presence of hypothyroidism in pregnant women with COVID-19 correlates with lower maternal uric acid levels and a slight decrease in INR values. The one-minute Apgar score correlates with the level of uric acid in pregnant women with SARS-CoV-2 infection and hypothyroidism.

Pain control and neonatal outcomes in 211 women under epidural anesthesia during childbirth at high altitude in Qinghai, China.

Background: High altitudes are characterized by low-pressure oxygen deprivation. This is further exacerbated with increasing altitude. High altitudes can be associated with reduced oxygenation, which in turn, can affect labor, as well as maternal and fetal outcomes. Epidural anesthesia can significantly relieve labor pain. This study aimed to assess the effects of elevation gradient changes at high altitude on the analgesic effect of epidural anesthesia, labor duration, and neonatal outcomes. Methods: We divided 211 women who received epidural anesthesia into groups according to varying elevation of their residence (76 in Xining City, mean altitude 2,200 m; 63 in Haibei Prefecture, mean altitude 3,655 m; and 72 in Yushu Prefecture, mean altitude 4,493 m). The analgesic effect was assessed using a visual analog scale (VAS). Labor duration was objectively recorded. The neonatal outcome was assessed using Apgar scores and fetal umbilical artery blood pH. Results: VAS scores among the three groups did not differ significantly (p > 0.05). The neonatal Apgar scores in descending order were: Xining group > Haibei group > Yushu group (p < 0.05). The stage of labor was similar among the three groups (p > 0.05). Fetal umbilical artery blood pH in descending order were: Xining group > Haibei group > Yushu group (p < 0.05). Conclusion: Elevation gradient changes in highland areas did not affect the efficacy of epidural anesthesia or labor duration. However, neonatal outcomes were affected.

An esophagectomy surgical Apgar score-based nomogram-a risk-based postoperative triage system: a phase II randomised trial.

Background: The esophagectomy surgical Apgar score (eSAS) has been found to be a predictor of postoperative complications in esophagectomy. In our previous study, we built a graphic nomogram based on eSAS and demonstrated that it can effectively predict the risk of major morbidity after esophagectomy. In this study, we aimed to assess the benefits of using an eSAS-based nomogram model as a postoperative risk-based triage system for patients undergoing esophagectomy. Methods: We enrolled 119 patients diagnosed with esophageal carcinoma and randomly assigned them to a nomogram group (NG) or control group (CG) from January 2019 to December 2020. Patients in the NG were assigned to a low-risk group and high-risk group based on the nomogram. Patients in the high-risk group were admitted to the intensive care unit (ICU) after esophagectomy. Risk estimation in the CG patients was based on the surgeon's clinical experience. Thirty-day major complications, postoperative hospital stay, hospital costs, and quality of life (QOL) during the follow-up were compared between the two groups. Results: Baseline clinicopathological characteristics were comparable between the NG (n=58) and CG (n=61). All patients underwent esophagectomy. Postoperative complications were significantly higher in the CG (30, 49.2%) than in the NG (14, 24.1%) (P=0.008), with pneumonia being the most common (CG: 23, 37.7%; NG: 12, 20.7%; P=0.042). There was no significant difference in anastomotic leakage (NG: 1, 1.7%; CG: 6, 9.8%; P=0.12). Postoperative median hospital stay was shorter in the NG (14 days) than in the CG (16 days) (P=0.041). Hospital costs (NG: ¥60,045.1; CG: ¥63,961.5; P=0.21) and postoperative QOL did not differ significantly between groups. Conclusions: An eSAS-based nomogram as a triage system can reduce the overall occurrence of postoperative complications and shorten postoperative hospital stay without increasing hospital costs.

Determinants of low Apgar score among newborns delivered by Cesarean section in Nigist Eleni Mohammed memorial specialized hospital, Southern Ethiopia.

A variety of factors can predispose newborns to have a low Apgar score after delivery. Identification of the determinants of low Apgar scores is an important first step to take to apply the necessary precautions. This study aimed to identify the determinants of low fifth-minute Apgar score after a Cesarean section. An institutional-based case-control study was conducted among mothers who deliver their newborns by Cesarean section in Nigist Eleni Mohammed Memorial Comprehensive Specialized Hospital, Ethiopia, from July 1, 2022, to September 30, 2022. Data were collected from 70 cases and 140 controls using a semi-structured checklist. A systematic random sampling technique was used to select both charts of mothers with cases and controls. Charts of mothers with newborns Apgar score less than 7 were considered as cases; whereas a similar group of charts of mothers with newborns with fifth-minute Apgar score greater than or equal to 7 were categorized as control. Descriptive statistics and bivariable and multivariable binary logistic regression analyses were conducted to describe the mothers and newborns and identify determinants of the fifth-minute low Apgar score, respectively. Adjusted odds ratios (AOR) with their respective 95% confidence interval (CI) were used to declare the determinant factors, and the statistical significance was set at P < 0.05. In total, 140 controls and 70 cases of mothers charts were enrolled in this study. The Mean ± SD age of mothers of cases and controls were 26.9 ± 4.9 and 27.06 ± 4.1 years, respectively. General anaesthesia (AOR = 4.2; 95% CI: 1.9 ‒ 9.3), rural residence (AOR = 3.7, 95% CI, 1.7‒8.1), low birth weight (AOR = 3.2, 95% CI, 1.3‒7.8), and emergency Cesarean section (AOR = 2.6; 95% CI: 1.2 ‒ 5.8) were identified determinant factors of low fifth minute Apgar score. A fifth-minute low Apgar score was significantly associated with newborns delivered through emergency Cesarean section, low birth weight, rural residence, and delivered from mothers who had undergone Cesarean section under general anaesthesia.

Risk of Transient Tachypnea of the Newborn following Elective Cesarean Section Increases at a Gestational Age of 37 Weeks Compared to That at ≥ 38 Weeks Despite the Exclusion of Pre-Existing Risk Factors for Neonatal Respiratory Disorders.

Background: Elective cesarean sections (ECSs) for early-term pregnancies at 37 weeks of gestational age (GA) aim to reduce the risk of emergency cesarean sections due to the onset of labor or rupture of membranes. However, resultant increases in neonatal respiratory disorders, including transient tachypnea of the newborn (TTN) have been observed. However, few studies have elucidated the associated risk factors. Consequently, we aimed to determine whether differences existed in the clinical outcomes between neonates delivered via ECS at 37 weeks and those delivered at ≥ 38 weeks of GA. Methods: A retrospective analysis was conducted on 259 neonates born via ECS at Tottori University Hospital, between January 2013 and December 2019, with birthweights ≥ 2500 g and GAs > 37 weeks. The neonates were categorized into two cohorts: births at 37 and at ≥ 38 weeks of GA (37-week and 38-week cohorts). The principal clinical outcomes included the appearance, pulse, grimace, activity, and respiration (Apgar) scores, need for positive-pressure ventilation, incidence of TTN, and length of hospital stay. Results: No statistically significant differences were observed in the indications for ECS, sex, or birthweight between the two cohorts. The 37-week cohort exhibited a lower 1-min Apgar score than did the 38-week cohort, with no statistically significant differences between the two cohorts, at 5 min. Statistically significant differences were not observed in the need for positive-pressure ventilation during initial resuscitation or length of hospital stay for patients with TTN between the two cohorts. Notably, the 37-week cohort exhibited a significantly higher incidence of TTN than did the 38-week cohort. Conclusion: ECSs at 37 weeks of GA exhibited an increased risk of TTN than ECSs at ≥ 38 weeks of GA. Strategic neonatal care and adequate preparation can mitigate this risk without affecting the length of hospital stay.

Implementing a Bundle for Evidence-based Cesarean Delivery May Not Be As Beneficial as Expected: A Multi-center, Pre- and Post- Study.

BACKGROUND: Standardization of procedures improves outcomes. Though systematic reviews have summarized the evidence-based steps (EBS) of cesarean delivery (CD), their bundled implementation has not been investigated. OBJECTIVE: In this pre- and post-implementation trial, we sought to ascertain if bundled EBS of CD, compared to surgeon's preference, improves outcomes. STUDY DESIGN: A StaRI (Standards for Reporting Implementation Studies) compliant, multi-center pre- and post-implementation trial at 4 teaching hospitals was conducted. The pre-implementation period consisted of CD done based on the physicians' preferences for 3 months; educational intervention (e.g., didactics, badge cards, posters, video) occurred at the 4th month. CDs in post-implementation period employed the bundled EBS. A pre-planned 10% randomized audit of both groups assessed adherence and uptake of EBS. The primary outcome was a composite maternal morbidity (CMM), which included estimated blood loss > 1,000 mL, blood transfusion, endometritis, post-partum fever, wound complications, sepsis, thrombosis, ICU admission, hysterectomy, or death. The secondary outcome was a composite neonatal morbidity (CNM) and some of its components were 5-min Apgar score < 7, positive pressure oxygen use, hypoglycemia, or sepsis. A priori Bayesian sample size calculation indicated 700 CD in each group was needed to demonstrate 20% relative reduction (from 15% to 12%) of CMM with 75% certainty. Bayesian logistic regression with neutral priors was used to calculate likelihood of net-improvement in adjusted relative risk (aRR) with 95% credible intervals (CrI). RESULTS: A total of 1,425 consecutive CD (721 in pre- and 704 in post-implementation group) were examined. Audited data indicated that the baseline EBS utilization rate during the pre-implementation period was 79%; after the implementation bundled EBS of CD the audited adherence was 89%-an uptake of 10.0% of the EBS. In four aspects, the maternal characteristics differed significantly in the pre- and post-implementation periods: race/ethnicity, hypertensive disorder, and the relative contribution of the 4 centers to the cohorts and the gestational age at delivery, but the indications for CD and whether its duration was < versus > 60 min did not. The rates of CMM in the pre- and post-implementation groups were 26% and 22%, respectively (aRR, 0.88; 95% CrI, 0.73-1.04), with a 94 % Bayesian probability of a reduction in CMM. The CNM occurred in 37% of the pre- and in 41% of the post-implementation group (aRR, 1.12; 95% CrI 0.98-1.39), with a 95% Bayesian probability of worsening in CNM. When CMM were segregated by preterm (<37 wks) and term (> 37 weeks) CD, the improvement in maternal outcomes persisted; when CNM were segregated by gestational age subgroupsthe potential for worsening neonatal outcomes persisted as well. CONCLUSIONS: Standardization of the evidence-based bundled steps of cesarean delivery resulted in a modest reduction of the composite maternal outcome; however, a paradoxical increase in neonatal composite morbidity was noted. Although individual evidence-based steps may be of value, while awaiting additional intervention trials a formal bundling of such steps is currently not recommended.

Relationship between maternal arterial and foetal cord carbon dioxide tension and neonatal outcome in critically ill pregnant women at delivery.

Background and Aims: No studies have evaluated the relationship between maternal arterial partial pressure of carbon dioxide (mPaCO2) and umbilical cord venous partial pressure of carbon dioxide (PCO2) in critically ill pregnant women at delivery. Based on the studies in healthy pregnant women, an mPaCO2 target of ≤50 mmHg is a suggested threshold during mechanical ventilation in critically ill parturients. We evaluated the relationship between mPaCO2 and neonatal cord gases in critically ill parturients at delivery as the primary objective. The relationship between mPaCO2 and APGAR scores at delivery was also analysed as a secondary objective. Methods: Maternal and neonatal cord gas data at delivery and APGAR scores were obtained by a retrospective chart review of 25 consecutive parturients with severe respiratory compromise who were delivered during mechanical ventilation. Linear regression was used to assess the relationship between mPaCO2 and umbilical artery and vein PCO2 and between mPaCO2 and APGAR scores at 1 and 5 min. Results: There was a positive correlation between mPaCO2 and neonatal cord venous PCO2 (P = 0.013). Foetal venous PCO2 exceeded predelivery mPaCO2 by 17.5 (7.5) mmHg. There was an inverse relationship between mPaCO2 and neonatal APGAR scores at 1 and 5 min (P = 0.006 and P = 0.007, respectively). Conclusion: Foetal cord venous PCO2 can be predicted if mPaCO2 values are known. Unlike in healthy pregnant women, there was an inverse relationship between rising mPaCO2 levels and neonatal APGAR scores in critically ill pregnant women who had several associated compounding factors.

Comparison of the effect of intravenous phenylephrine and norepinephrine boluses for post-spinal hypotension on neonatal outcome in elective caesarean section: A randomised controlled trial.

Background and Aims: There is limited data on the effects of norepinephrine on neonatal outcomes and maternal complications relative to other vasopressors. The study aimed to compare neonatal outcomes and maternal complications after bolus intravenous doses of phenylephrine and norepinephrine for post-spinal hypotension in elective caesarean section women. Methods: This randomised study was done on 100 elective caesarean section women under spinal anaesthesia. Block randomisation divided women into two groups to receive intravenous phenylephrine 50 µg bolus (Group A) or norepinephrine 5 µg bolus (Group B) following post-spinal hypotension. Groups were evaluated and compared for umbilical arterial blood gas analysis, birth weight, APGAR (appearance, pulse, grimace, activity, and respiration) score, maternal haemodynamics, and complications. Kolmogorov-Smirnov and Shapiro-Wilk tests were used to verify data normality. Independent samples t-test or Mann-Whitney U test was employed to compare continuous variables based on data normality, and the Chi-square test was used to determine categorical variable associations. Results: Demographic characteristics of women were found to be comparable between groups. Umbilical arterial potential of hydrogen, partial pressure of oxygen, partial pressure of carbon dioxide, base excess, bicarbonate, birth weight, and APGAR scores were comparable across groups, showing no significant differences (P > 0.05). Groups had similar maternal haemodynamic characteristics and episodes of nausea, vomiting, and chest pain across groups without statistical significance (P > 0.05). Conclusion: No notable distinction was found between neonatal outcomes and maternal complications between phenylephrine and norepinephrine bolus regimens. Norepinephrine can be used as an alternative to phenylephrine post-spinal hypotension in women undergoing elective caesarean section.

Cerebroplacental ratio and perinatal outcomes in mild-to-moderate idiopathic polyhydramnios cases.

OBJECTIVE: This study will evaluate whether fetal cerebroplacental ratio (CPR) can predict perinatal adverse outcomes in singleton pregnancies with mild and moderate idiopathic polyhydramnios (IP). METHOD: This study was designed as a prospective case-control study between January 2023 and November 2023. Pregnant women diagnosed with mild-to-moderate IP and low-risk singleton pregnancies were included in the study. In all cases, umbilical artery (UA) and middle cerebral artery (MCA) pulsatility indices (PIs) were measured at 36-40 weeks of gestation, and CPR was calculated. The group with polyhydramnios was divided into two parts according to whether the CPR value was below 1.08 or 1.08 and above. Perinatal outcomes of all groups were compared. RESULTS: A total of 140 patients were included in the study. Seventy of these were IP cases, and 70 were low-risk pregnant women. UA PI in the IP group was not statistically different from that in the low-risk group, but MCA PI and CPR were significantly lower in the IP group (P = 0.07, P = 0.001, and P = 0.004, respectively). IP cases were divided into a low group (<1.08, n = 18) and a normal group (≥1.08, n = 52) according to the CPR value. Cesarean section rates due to fetal distress were significantly higher in the low-CPR group (n = 8 [44.4%] vs 5 [9.6%], P = 0.001). In the low-CPR group, 5-min Apgar <7, and neonatal intensive care unit (NICU) admission rates were significantly higher (P = 0.045 and P = 0.001, respectively). CONCLUSION: It is encouraging that in cases with mild-to-moderate IP, low CPR predicts emergency delivery due to fetal distress, a low Apgar score at 5 min, and NICU admission.

Maternal and neonatal effects of epidural levobupivacaine combined with fentanyl or sufentanil for elective cesarean-section in brachycephalic breeds.

The aim of this study was to compare the safety and clinical efficacy of epidural levobupivacaine combined with fentanyl or sufentanil for bitches undergoing elective cesarean-section and the impact of these anesthetic protocols on neonatal viability. The anesthetic protocol consisted of intramuscular morphine (0.2 mg/kg), followed by an intravenous bolus of propofol, in a dose sufficient to allowed the puncture of the lumbosacral space. The dogs were randomly allocated to receive 0.5 % levobupivacaine plus fentanyl (2.5 µg/kg; LF: n = 9) or sufentanil (1 µg/kg; LS; n = 11). Maternal cardiorespiratory parameters were monitored at specific time points during surgery. Intraoperative propofol supplementation was based on the presence of head and/or thoracic limb movements. Neonatal reflex responses and the Apgar score (range 0-10 points) were assessed at 5 and 60 minutes after birth. Puppy mortality rate was recorded until 24 hours after birth. Data were analyzed using two-way ANOVA, Tukey's test, Wilcoxon signed rank test, and Fisher's exact test (P < 0.05). Intraoperatively, maternal cardiorespiratory variables and propofol requirements were similar between groups, with no detection of anesthetic complications. The puppy reflex responses did not differ between groups at any time point. The medians (range) of Apgar scores were lower (P = 0.016) in the LF [5 (1-9)] at 5 minutes in comparison with LS [6 (2-9)], while no intergroup differences were recorded at 60 minutes [LF = 8 (2-10); LS = 9 (6-10]. The total mortality rate was 4.1 %. In the LS group, no puppies died, while in the LF 8 % of the puppies died in the first 24 hours after birth (P = 0.11). Epidural levobupivacaine combined with fentanyl or sufentanil provided minimal maternal and neonatal adverse effects, but neither protocol enabled the performance of a C-section in 100 % of the French and English bulldogs, without propofol supplementation.

Water birth: a systematic review and meta-analysis of maternal and neonatal outcomes.

OBJECTIVE: This systematic review and meta-analysis aimed to conduct a thorough and contemporary assessment of maternal and neonatal outcomes associated with water birth in comparison with land-based birth. DATA SOURCES: We conducted a comprehensive search of PubMed, EMBASE, CINAHL, and gray literature sources, from inception to February 28, 2023. STUDY ELIGIBILITY CRITERIA: We included randomized and nonrandomized studies that assessed maternal and neonatal outcomes in patients who delivered either conventionally or while submerged in water. METHODS: Pooled unadjusted odds ratios with 95% confidence intervals were calculated using a random-effects model (restricted maximum likelihood method). We assessed the 95% prediction intervals to estimate the likely range of future study results. To evaluate the robustness of the results, we calculated fragility indices. Maternal infection was designated as the primary outcome, whereas postpartum hemorrhage, perineal lacerations, obstetrical anal sphincter injury, umbilical cord avulsion, low Apgar scores, neonatal aspiration requiring resuscitation, neonatal infection, neonatal mortality within 30 days of birth, and neonatal intensive care unit admission were considered secondary outcomes. RESULTS: Of the 20,642 articles identified, 52 were included in the meta-analyses. Based on data from observational studies, water birth was not associated with increased probability of maternal infection compared with land birth (10 articles, 113,395 pregnancies; odds ratio, 0.93; 95% confidence interval, 0.76-1.14). Patients undergoing water birth had decreased odds of postpartum hemorrhage (21 articles, 149,732 pregnancies; odds ratio, 0.80; 95% confidence interval, 0.68-0.94). Neonates delivered while submerged in water had increased odds of cord avulsion (10 articles, 91,504 pregnancies; odds ratio, 1.75; 95% confidence interval, 1.38-2.24) and decreased odds of low Apgar scores (21 articles, 165,917 pregnancies; odds ratio, 0.69; 95% confidence interval, 0.58-0.82), neonatal infection (15 articles, 53,635 pregnancies; odds ratio, 0.64; 95% confidence interval, 0.42-0.97), neonatal aspiration requiring resuscitation (19 articles, 181,001 pregnancies; odds ratio, 0.60; 95% confidence interval, 0.43-0.84), and neonatal intensive care unit admission (30 articles, 287,698 pregnancies; odds ratio, 0.56; 95% confidence interval, 0.45-0.70). CONCLUSION: When compared with land birth, water birth does not appear to increase the risk of most maternal and neonatal complications. Like any other delivery method, water birth has its unique considerations and potential risks, which health care providers and expectant parents should evaluate thoroughly. However, with proper precautions in place, water birth can be a reasonable choice for mothers and newborns, in facilities equipped to conduct water births safely.
