Introduction: Hypertensive Disorders in Pregnancy (HDP), is a common complication of pregnancy leading to majority of adverse perinatal outcome. The timely diagnosis of fetal compromise, before irreversible damage, is possible by doing Cerebroplacental Ratio (CPR), on doppler ultrasonography. CPR is calculated as ratio of Pulsatility Index (PI) of Middle cerebral Artery and Umblical Artery (UA). It reflects both the circulatory insufficiency in UA along with adaptive changes in Middle cerebral Artery (MCA). Aim: To evaluate role of Cerebroplacental Ratio as predictor of Fetal Growth Restriction and perinatal outcome in singleton pregnancy with HDP at 28-41 weeks of gestation. Materials and Methods: A prospective observational cohort study was carried out in the Department of Obstetrics and Gynaecology, Vardhman Mahavir Medical College and Safdarjung Hospital, New Delhi, India. The study included 150 women with singleton pregnancy, HDP and 28-41 weeks of gestation. Doppler ultrasound was performed and CPR calculated as ratio of MCA PI and UA PI, using ultrasound study performed within two weeks of delivery. All women were followed-up till delivery and perinatal outcome i.e., birth weight, preterm birth, cesarean for fetal distress, Meconium Stained Liquor (MSL) , APGAR at 5 minutes, still birth, Neonatal Intensive Care Unit (NICU) admission and early neonatal death, were recorded. The data entry was done in the Microsoft excel spreadsheet and the final analysis was done with the use of Statistical Package for Social Sciences (SPSS) software version 21.0. Results: Out of 150 women, 20% (30) had abnormal CPR. Abnormal CPR had significant association with Low Birth Weight (LBW) (p-value=0.0001), preterm delivery (p-value=0.0001), fetal distress (p-value=0.0001), caesarean for fetal distress (p-value=0.0001), 5-minute APGAR score <7 (p-value=0.0001), NICU admission (p-value=0.0001), Meconium Stained Liquor (MSL) (p-value=0.0001) and neonatal death (p-value=0.025). CPR had 100% sensitivity and 100% Negative Predictive Value (NPV) for predicting adverse perinatal outcome with diagnostic accuracy of 47.33%. Conclusion: The CPR is an independent predictor of Fetal Growth Restriction (FGR) in women with HDP. It can also independently predict perinatal outcome in women with HDP with or without FGR. Abnormal CPR had 100% sensitivity for identifying women with high risk of adverse perinatal outcomes, whereas normal CPR, with NPV of 100%, almost excludes it.

Background: Hypertensive disorders of pregnancy (HDP) pose significant risks to maternal and fetal health, with substantial mortality and morbidity rates globally, particularly in developing countries. Pre-eclampsia (PE) accounts for a notable portion of maternal morbidity and mortality, with varied prevalence across regions within countries like India. Despite advancements, disparities in healthcare access persist, influencing outcomes. PE not only affects maternal health during pregnancy but also predisposes women to long-term cardiovascular complications, emphasizing the need for early screening and preventive measures. Methods: This prospective randomized double-blind clinical trial aims to compare the efficacy and safety of 75 mg versus 150 mg aspirin for preventing preterm pre-eclampsia in high-risk women. Screen-positive women aged 18–45 years with singleton pregnancies between 12 and 16 weeks of gestational age will be enrolled. They will be randomized in a 1:1 ratio to receive either 75 mg or 150 mg of aspirin nightly until 37 weeks of pregnancy or earlier if preterm pre-eclampsia develops. Feto-maternal outcomes, including preterm pre-eclampsia incidence and neonatal and maternal complications, will be assessed. The sample size calculation based on expected proportions of preterm pre-eclampsia in both groups indicates a total of 370 participants (185 per group) accounting for 20% attrition. Discussion: This prospective randomized double-blind clinical trial aims to compare the effectiveness and safety of two doses of aspirin (75 mg vs 150 mg) in preventing preterm pre-eclampsia in high-risk women. The potential implications of this study are significant, including the optimization of aspirin prophylaxis, the development of evidence-based guidelines, and comprehensive assessment of maternal and fetal outcomes. In conclusion, the results of this study have the potential to significantly impact clinical practice by enhancing maternal and perinatal health outcomes and contributing to evidence-based obstetric care.

Introduction: Preeclampsia and eclampsia are hypertensive disorders of pregnancy associated with significant maternal and fetal morbidity and mortality. Posterior reversible encephalopathy syndrome (PRES) is a neurological complication observed in these conditions, yet its impact on fetomaternal outcomes remains underexplored. The aim of this study is to investigate the association between PRES and fetomaternal outcomes in women with preeclampsia and eclampsia. Methods: This prospective cohort study enrolled 64 singleton pregnant women beyond 20 weeks of gestation with preeclampsia and eclampsia having neurological symptoms. Participants underwent clinical evaluation and radiological assessment, including non-contrast computed tomography (NCCT) and magnetic resonance imaging (MRI). Maternal outcomes, including high dependency unit (HDU)/intensive care unit (ICU) stay, intubation, mode of delivery and maternal mortality. Fetal outcomes, i.e., stillbirth, prematurity, and neonatal intensive care unit (NICU) stay, were recorded. Statistical analysis was performed to compare outcomes between PRES and non-PRES groups. Results: The majority (92.18%) of participants were unscheduled and (56.2%) were primigravida. PRES was diagnosed in 62.5% of cases, predominantly associated with antepartum eclampsia (47.5%). Neurological symptoms such as headache (85.9%) and blurring of vision (68.8%) were common in PRES cases. Cesarean section rate was significantly higher in PRES group (75%), along with adverse outcomes including increased HDU/ICU stay, intubation, postpartum haemorrhage (PPH), abruption, maternal mortality, stillbirth, prematurity, fetal growth restriction (FGR), meconium-stained liquor (MSL), and NICU stay, which were observed significantly higher in women with PRES ( p < 0.001) and low Appearance, Pulse, Grimace, Activity, and Respiration (APGAR) scores ( p < 0.05). However, no significant association was observed between PRES and early neonatal death (ENND). Conclusion: PRES is associated with adverse fetomaternal outcomes in women with preeclampsia/eclampsia, including higher cesarean section rate and increased maternal and neonatal morbidity. Early recognition and management of PRES are crucial for improving outcomes in these high-risk pregnancies. Further research with larger sample sizes is warranted to validate these findings and explore potential interventions.

Introduction: Preeclampsia (PE) remains a significant cause of maternal and neonatal morbidity and mortality worldwide, necessitating effective prevention strategies. Low-dose aspirin has been proposed as a preventive measure for women at high risk of developing PE, given its role in modulating platelet aggregation and improving placental perfusion. However, questions regarding optimal dosage, timing, and effectiveness across diverse populations persist. This systematic review and meta-analysis aimed to synthesize evidence from randomized controlled trials (RCTs) to evaluate the efficacy of low-dose aspirin in reducing the incidence of PE. Methods: A comprehensive search was conducted across databases and registers, identifying 850 records. After removing duplicates and excluding studies based on eligibility criteria, 33 RCTs were included. Data were extracted on aspirin dosage, timing of initiation, continuation duration, and PE outcomes. Meta-analysis was performed to evaluate the protective effect of aspirin, and study quality was assessed using bias scoring. Results: Low-dose aspirin (75–150 mg) significantly reduced PE incidence in high-risk women. Early initiation, particularly between 12–16 weeks, demonstrated enhanced efficacy. Higher doses, such as 150 mg, were associated with better outcomes compared to lower doses. Variability among studies was noted due to differences in populations, aspirin protocols, and methodological quality. Bias assessments indicated moderate quality across most studies. Conclusion: Low-dose aspirin, initiated early in pregnancy, effectively reduces PE risk in high-risk women. Findings support integrating aspirin therapy into prenatal care guidelines, with tailored dosing based on patient risk profiles. Future research should refine protocols and explore long-term maternal and neonatal outcomes.
