SummaryNormal pregnancy is associated with profound alterations in the coagulation and fibrinolytic systems. While these physiological procoagulant changes are aimed to minimise intrapartum blood loss, they do increase the risk of thromboembolism during pregnancy and the post-partum period. In contrast and more rarely, haemorrhage due to an underlying inherited or acquired bleeding disorder may occur and complicatea pregnancy. Based on an analysis of the literature data, this review presents an overview of the main thrombotic and haemorrhagic disorders complicating pregnancy.

ABSTRACT Peripheral plasma levels of oestrogens1), progesterone and 17α-hydroxyprogesterone were measured during normal pregnancy in seven rhesus monkeys. The plasma concentrations of oestrogens ranged between 200 and 1300 pg/ml throughout the gestation period. Increases in the levels of oestrogens in plasma occurred several days before parturition. The plasma concentrations of progesterone ranged between 0.5 and 22 ng/ml during pregnancy. The concentrations of oestrogens decreased dramatically after parturition and remained low during the post-partum period. The concentration of progesterone decreased after parturition, but did not reach follicular phase levels during the period observed. The plasma levels of 17α-hydroxyprogesterone were low throughout the gestation period and during the post-partum period.

Introduction: Postpartum haemorrhage is one of the leading causes of maternal death worldwide and it accounts for nearly one-quarter of all maternal deaths and almost half of all postpartum deaths in low-income countries. Primary postpartum haemorrhage (PPH) is the most common form of major obstetric haemorrhage. Materials and Methods: The study protocol was comprised of Consent, Measurement of Pre-delivery Hemoglobin, Administration of the Intervention, Measurement of postpartum blood loss and Measurement of Post-delivery (24-48 hours) Hemoglobin. Blood loss was measured using a calibrated drape. The drape was placed beneath the parturient buttocks and secured around her abdomen with ties. Blood loss was monitored for a minimum of one hour and was continued in the second hour in case of persistent bleeding. The drape with the collected blood was weighed on a scale. The weight of the drape and the container in which it is placed was deducted from the total recorded weight in order to obtain the weight of the blood collected in the drape. Blood loss weight in grams was converted to milliliters by dividing the figure in grams by 1.06 (blood density in grams per milliliter). Results: The cross tabulations were used to study the demographic, obstetrical and medical factors in women with obstetrical haemorrhage. Table 1 shows the selected sociodemographic characteristics of the study population. The mean age of cases and controls are 26.333.559 and 26.853.873 respectively. On comparison, they are statistically insignificant. (p=0.324). The educational, occupational and socioeconomic status was comparable between cases and controls (p >0.05). Table 2 shows Antenatal, intra-partum and post-partum data in cases and controls. Discussion & Conclusion: It is a study done in North India comparing the Oxytocin kept at room temperature with failure of maintenance of cold chain during transport and storage and the refrigerated Oxytocin. It is the common understanding and general training that Oxytocin must be stored in the refrigerator, failing which its efficacy reduces i.e. it, will not be effective in controlling PPH. During the study we compared the mean blood loss and change in hemoglobin levels in cases and control and despite the fact that major risk factor for PPH for example past history of PPH, past history of D&C, prolonged third stage labour duration, manual removal of placenta were comparable in both cases and controls, still the mean blood loss and change in hemoglobin values was more in cases than controls. This could be attributed to usage of market oxytocin which had failed cold chain maintenance resulted in less effective oxytocin in prevention of PPH, Hence causing more blood loss and drop in hemoglobin values. This shows the need of room temperature stable uterotonic drug in LMIC’s like ours. Recently room temperature stable carbetocin shows the potential as an effective uterotonic drug for the prevention of PPH. However according to various studies carbetocin cannot be used for induction or augmentation of labour so it cannot replace oxytocin fully, rather it acts as a part of collective PPH reduction strategy.

Abstract Objectives Maternal race, marital status, and social environment impact risk of preterm delivery and size for gestational age. Although some paternal characteristics such as age are associated with pregnancy outcomes, the influence of the paternal presence, race/ethnicity and adverse life events is not well known. The objective of the study was to assess birth outcomes in mothers with a paternal presence compared to those without during the post-partum period. The secondary aim was to determine whether paternal race is associated with birth outcomes. Methods This was a cross-sectional study using parental surveys linked with birth certificate data from 2016 to 2018. Adverse birth composite outcomes (ABCO) including small for gestational age (SGA), prematurity or neonatal intensive care unit admission (NICU) were assessed. Results A total of 695 parents were analyzed (239 single mothers and 228 mother-father pairs). Compared to mothers with a father present, mothers without a father present exhibited increased odds of ABCO, prematurity and NICU. Non-Hispanic Black fathers had increased odds of ABCO and NICU compared to Non-Hispanic Whites (NHW). Hispanic fathers had increased odds of NICU compared to NHW. Conclusions Paternal absence in the post-partum period and paternal race were both independently associated with ABCO and NICU. Assessment of paternal presence and paternal race in clinical practice may help identify opportunities for additional support necessary to optimize birth outcomes.

Background: Prior studies have compared the E/e’ elevation in preeclampsia patients to normal patients, however there are no data whether this elevation persists after birth. The aim of this study is to analyze diastolic function in preeclampsia patients during pre- and post-partum period using E/e’ parameter measurement.Methods: This is a prospective cohort study of pregnant women with preeclampsia who were hospitalized and planned for pregnancy termination. Basic clinical characteristics were obtained from all samples. Echocardiography was done prepartum, 48-72 hours after termination, and 40-60 days postpartum. Post hoc analysis using least significant difference method was used to compare the results between measurements.Results: 30 subjects were enrolled in the study. Analysis on E/e’ characteristics showed statistical difference between prepartum E/e’ and 40 days postpartum E/e’ (11.87±3.184 vs 9.43±2.529, p=0.001, CI=1.123-3.751), as well as between 48 hours post-partum and 40 days post-partum period (12.12±2.754 vs 9.43±2.529, p<0.001, CI=1.615-3.771). There were no statistical differences between pre-partum E/e’ and 48 hours post-partum E/e’ (11.87±3.184 vs 12.12±2.754, p=0.633, CI=-1.345-0.832).Conclusion: This study showed diastolic dysfunction in preeclampsia patients persists up until a few days after birth, but resolves in time (40 days after birth) as measured by tissue doppler imaging.
