Background: High risk pregnancies increase the maternal and fetal morbidity and mortality; and there is a need for appropriate investigation which can diagnose it early and predicts the morbidity and mortality. The objectives of this study were to compare the efficacy of Doppler velocimetry studies and NST in predicting fetal compromise in utero and compare their ability in predicting the perinatal outcome in cases of high risk pregnancies.Methods: It was a prospective cross-sectional hospital based study conducted at Central Referral Hospital (CRH) which is a teaching hospital of Sikkim Manipal Institute of Medical Sciences (SMIMS). The study was conducted over a period of eighteen months between November 2012 and April 2014. One hundred consecutive cases of high risk pregnancies were enrolled into the study and investigated with NST (non-stress test) and Doppler velocimetry and results were correlated with perinatal outcome. In all cases, accurate gestational age was established from detailed menstrual history and ultrasonographic evidence of gestational age. Detailed examination, history and investigation were undertaken in each patient. Inclusion criteria were patients with singleton pregnancy beyond 34 weeks having one or more high risk factors. In these patients antenatal surveillance was done by Doppler and NST and results of these tests were correlated with perinatal outcome. Based on the Doppler velocimetry and NST results, the study population was divided in to four groups. Pregnant women below 34 weeks, multiple pregnancy and women with no risk factors were excluded from the study.Results: Maximum (63%) patients belonged to pregnancy induced hypertension (PIH) group, followed by oligohydramnios (11%), and gestational diabetes mellitus (GDM). The study showed that patients with both NST and Doppler waveform abnormal (group D) had the highest percentage of neonatal complication, NICU admissions and perinatal deaths. Even those patients with NST normal but Doppler velocimetry abnormal (group B) had comparatively higher neonatal complications. However, in group with NST abnormal and Doppler velocimetry normal (group C) had no fetal compromise. It was observed that normal NST and normal Doppler velocimetry were not statistically different in predicting fetal compromise and prediction value was low. But abnormal Doppler had statistically significant (p value = 0.021) predictive value in detecting fetal compromise. In cases with abnormal Doppler and fetal compromise, NST was still normal showing that abnormal Doppler waveform was better in predicting the bad perinatal outcome. Three out of 100 cases had absent end diastolic flow (AEDF) and all 3 were associated with perinatal morbidity with 2 perinatal deaths. Cerebroplacental ratio was < 1.08 in seven cases and all seven had neonatal complications including 3 neonatal deaths which also had AEDF. Thus, cerebroplacental ratio was better in detecting fetal compromise as compared to NST.Conclusions: Doppler velocimetry was better in predicting fetal compromise in comparison to NST in high risk pregnancies. Normal NST and normal Doppler velocimetry were not significantly different in prediction of fetal outcome. Abnormal Doppler value was better in predicting fetal compromise in comparison to abnormal NST.

Background: Pregnancy is a unique, physiologically normal event in a women’s life. Objective of this study was to compare the efficacy of the doppler velocimetry versus non stress test in relation to perinatal outcome in high risk pregnancies.Methods: This is a prospective study conducted in the department of obstetrics and gynaecology, Narayana Medical College and Hospital. 100 women with high risk pregnancy were recruited. All were examined systematically, and Doppler velocimetry and non-stress test were done.Results: All cases were divided into four groups based on NST and doppler velocimetry of umbilical artery and middle cerebral artery. 10% of women had abnormal doppler. Middle cerebral artery doppler abnormality was noted in 3% and CPR abnormality in 3% of women in the study group. 15% had abnormal NST. In Group A, out of 88 patients 9 had fetal compromise. In Group B, out of 5 patients all had fetal compromise. In Group C, out of 4 patients none had fetal compromise. In Group D, all 3 patients had fetal compromise. In Group D, all 3 had neonatal deaths. Average birth weights in Group A was 2.7 kg, in Group B was 2 kg, in Group C was 2.5 kg, in Group D was 1.4 kg. Two (2.2%) newborn in Group A, 4 (80%) newborns in Group B, 3 (100%) in Group had Apgar < 7 at 5 minutes. 4 (4.5%) babies in Group A, 5 (100%) babies in Group B, 3 (100%) babies in Group D were admitted in NICU. Umbilical artery doppler was found to have sensitivity 46.6%, specificity - 94%, PPV - 93%, NPV - 54%. Middle cerebral artery doppler was found to have sensitivity 73.3%, specificity - 90%, PPV - 91.6%, NPV- 69.3%.Conclusions: In present study, highest percentage of perinatal complications and perinatal deaths were seen in groups with abnormal tests of NST and velocimetry. Group D had the worst perinatal outcome.

A Prospective Study

This was a prospective study conducted in pregnant patients with high risk factors who got admitted in the Department of Obstetrics and Gynaecology at Care Hospital, Jamnagar during the period from May 2018 to September 2020. Background: High-risk pregnancies causes many adverse perinatal outcomes. Doppler ultrasound is a non-invasive technique to study the feto-maternal circulation to guide the clinical management. Objective: This study aims at evaluating the role of colour Doppler in high-risk pregnancies and their perinatal outcome. Materials and Methods: This was a prospective study carried out for 29 months in the Department of Radiology with antenatal women in the age group of 18-35 years with singleton pregnancy of gestational age of <28 weeks to >35 weeks having high-risk factors considered in study. The risk factors considered were pregnancy induced hypertension (PIH), gestational diabetes, anemia, oligohydramnios, polyhydramnios and IUGR. Doppler study of umbilical artery and fetal middle cerebral artery (MCA) arteries was done and amniotic fluid index (AFI) was measured. Parameters in the form of resistive index, pulsatility index, and systolic/diastolic ratio were taken. obstetric history was taken with regular interval follow up. Results: The study was carried out with 50 patients. High-risk pregnancy was more common in the age group of 21-25 years. The most common high-risk factor in pregnancy was oligohydramnios which accounted for 30% of cases. Out of 50 high-risk pregnancies, 5 (10 %) of cases resulted in intrauterine growth restriction (IUGR). Out of 50 high-risk cases, in 36 cases, umbilical artery findings were abnormal. 3 patients had intrauterine death (IUD) and 27 patients had poor perinatal outcome. Umbilical artery abnormality showed significant sensitivity and negative predictive value for adverse (poor + IUD) perinatal. Correlation was seen between high risk pregnancy and need of emergency caesarean section and induction and associated adverse perinatal outcome. Conclusion: Combination of different arterial waveform study enhance the diagnostic accuracy in identifying those intrauterine growth restricted foetuses that were at risk. Keywords: Colour Doppler, high risk pregnancy, perinatal outcome.

Twin Pregnancies

Twin pregnancies are categorized according to three factors, zygosity, chorionicity and amnionicity. Dizygotic twins are always dichorionic and diamniotic, where each twin has its own chorionic and amniotic sac. Monozygotic twins account for 1/3 of twin pregnancies and show higher morbidity and mortality. In monozygotic twins, chorionicity and amnionicity are determined by the time of zygote division. Chorionicity and amnionicity determine the risks of twin pregnancy. Morbitidies are shown notable decreasing tendency depending on improving of high risk obstetric and neonatal care, however is still discussed the optimum labour management in twin pregnancies Vaginal delivery in twin pregnancies is possible when both have cephalic presentation and in the late weeks of pregnancy during which the risks of prematurity are minimized. The aim of this review was the assessment and evaluation the impact of the labour modus and timing of termination of twin pregnancies due to rise of their occurrence based on scientific aspects of the new published literature on perinatal outcome.

Objective To evaluate the effect of aspirin dose on the incidence of all gestational age preeclampsia and preterm preeclampsia. Data sources Electronic databases (Cochrane, PubMed, Scopus, ClinicalTrials.gov and the Web of Science) were searched for articles published between January 1985 and March 2019 with no language restrictions. Methods We followed the PRIMSA guidelines and utilized Covidence software. Articles were screened by 2 independent reviewers, with discrepancies settled by an independent 3rd party. Study selection criteria were randomized trials comparing aspirin for prevention of all gestational age and preterm preeclampsia to placebo or no antiplatelet treatment in women aged 15–55 years with moderate or high-risk factors according to the list of risk factors from American College of Obstetricians and Gynecologists and United States Preventive Services Task Force guidelines. The quality of trials was assessed using the Cochrane risk of bias tool. The data were pooled using a random-effects meta-analysis comparing aspirin at doses of <81, 81, 100, and 150 mg. Pre-specified outcomes were all gestational age and preterm preeclampsia. Results Of 1,609 articles screened, 23 randomized trials, which included 32,370 women, fulfilled the inclusion criteria. In preterm preeclampsia, women assigned at random to 150 mg experienced a significant 62% reduction in risk of preterm preeclampsia (RR = 0.38; 95% CI: 0.20–0.72; P = 0.011). Aspirin doses <150 mg produced no significant reductions. The number needed to treat with 150 mg of aspirin was 39 (95% CI: 23–100). There was a maximum 30% reduction in risk of all gestational age preeclampsia at all aspirin doses. Conclusions In this meta-analysis, based on indirect comparisons, aspirin at a dose greater than the current, recommended 81 mg was associated with the highest reduction in preterm preeclampsia. Our meta-analysis is limited due to the deficiency of homogeneous high evidence data available in the literature to date; however, it may be prudent for clinicians to consider that the optimal aspirin dose may be higher than the current guidelines advise. Future research to compare the efficacy aspirin doses greater than 81 mg is recommended. Study registration PROSPERO, CRD42019127951 (University of York, UK; http://www.crd.york.ac.uk/PROSPERO/).

Intravenous Hydration

Background: Adequate amount of amniotic fluid was required for normal growth of fetus. Oligohydramnios or reduced amount of amniotic fluid is associated with adverse maternal and perinatal outcome due to increase in induced labour and operative deliveries. Idiopathic oligohydramnios is a condition in which no other risk factors are associated with pregnancy. This study was done to compare the effect of L-arginine and IV hydration on improvement of amniotic fluid index and fetal growth.Methods: Total 50 patients were included in the study according to inclusion criteria and divided equally into two groups randomly. IV hydration was given to one group and other group received L- arginine sachet orally. The effect on AFI and fetal outcome was compared.Result: The result was compared with respect to age, gravidity, gestational age and AFI at the time of study and after giving treatment. Maternal and fetal outcome was compared which shows that L-arginine was more effective in increasing the AFI and thereby leading to favorable results in the form of increase in gestational age at time of delivery and fetal weight.Conclusion: This study shows that both IV hydration and L-arginine are useful in treatment of oligohydramnios. But L-arginine appears more advantageous over IV hydration in improving pregnancy outcome and reducing perinatal morbidity and mortality.

Background: Neonatal sepsis can cause multiorgan involvement causing neonatal morbidity and mortality. The kidneys are an important organ affected in septicemic newborns. In this study we evaluated the renal functions and its association with various risk factors along with outcome in septicemic neonates.Methods: This study was a prospective observational study conducted in a tertiary care teaching hospital. The sample size was 276 cases of septicemic new-borns and study duration was 2 years. The profile of acute renal failure (ARF) and various risk factors were studied in a sample of 276 septicemic neonates. Detailed clinical examination and investigations were done to confirm the diagnosis of neonatal sepsis and the occurrence of ARF was studied among these septicemic newborns. Risk factors like birth weight, gestational age, shock, etiological agents, DIC were studied for the occurrence of ARF and mortality in ARF patients among septicemic neonates.Results: 30.07% of septicemic neonates developed ARF. DIC (p value=0.014), shock (p value=<0.0001), gestational age (p value=0.005), birth weight (p value=0.003), were found to be analytically significant for the occurrence of ARF. Birth weight (p value=0.006), age of onset of sepsis (p value=0.019), shock (p value =<0.0001), oliguria (p value =<0.0001), and DIC (p value=0.015) were significant predictors of mortality in ARF among septicemic neonates.Conclusions: Awareness and early identification of various risk factors and ARF in septicemic neonates can prevent morbidity and mortality among neonates.

OBJECTIVE: To determine morbidity and mortality rates by risk category in accordance with the American College of Chest Physicians guidelines, to determine what role pulmonary function tests play in this categorization process, and to identify risk factors for perioperative complications (PCs). METHODS: This was a historical cohort study based on preoperative and postoperative data collected for cases of lung cancer diagnosed or suspected between 2001 and 2010. RESULTS: Of the 239 patients evaluated, only 13 (5.4%) were classified as being at high risk of PCs. Predicted postoperative FEV1 (FEV1ppo) was sufficient to define the risk level in 156 patients (65.3%); however, cardiopulmonary exercise testing (CPET) was necessary for identifying those at high risk. Lung resection was performed in 145 patients. Overall morbidity and mortality rates were similar to those reported in other studies. However, morbidity and mortality rates for patients at an acceptable risk of PCs were 31.6% and 4.3%, respectively, whereas those for patients at high risk were 83.3% and 33.3%. Advanced age, COPD, lobe resection, and lower FEV1ppo were correlated with PCs. CONCLUSIONS: Although spirometry was sufficient for risk assessment in the majority of the population studied, CPET played a key role in the identification of high-risk patients, among whom the mortality rate was seven times higher than was that observed for those at an acceptable risk of PCs. The risk factors related to PCs coincided with those reported in previous studies.
