Filter by:Obstetric Hemorrhage continues to be the first cause of maternal morbidity and mortality around the world especially in middle to low income countriesThe blood components are high value resources; however, its use has been shown to be a risk factor of known complications. The aim of the study is to compare two algorithms of coagulation management in massive obstetric hemorrhage Methods A randomized prospective trial single center two arms study in patients with severe obstetric hemorrhage (PPH > 1000) 2 different transfusion protocols one guided by thromboelastometry and hemostatic drugs (protrombine complex concentrate and fibrinogen concentrate) and the second guided by standard coagulation test and hemocomponents. Sample is calculated to known variance, Analyses are intention-to-treat without imputation, with outcomes will be performed between groups using mixed-effects two level regression models. For binary outcomes, a logistic model will be used and results presented as adjusted odds ratios (ORs) alongside 95% confidence intervals (CIs). Count data will be analysed using Poisson multilevel or negative binomial models. Primary Outcome Parameter: Compare between the two protocols: Number of allogeneic blood products transfused intra-op, within 24h after screening and in-hospital (RBC, Platelets and FFP; separate and overall) Secondary Outcome Parameter: Analysis of mortality, lenth of stay admission to the ICU, hysterectomy surgical reintervencion, Transfuse associated circulatory overload, Transfusion associated Acute lung injury, health associated infection will be measured as secondary outcome.

Purpose to evaluate the effects of sublingual misoprostol with or without intravenous tranexamic acid (TA) in comparison with placebo on reducing post-partum hemorrhage in pregnant women with twin pregnancy undergoing an elective cesarean section.
Postpartum haemorrhage keeps to be the leading cause of maternal mortality in middle and low-income countries, including Iraq. Much advancement had been made in the field of treatment for postpartum haemorrhage but no much progress had been made in the field of prevention, where one of its main component is the administration of uterotonic, preferably oxytocin, immediately after birth of the baby. In many low- and middle income countries, the efficacy of oxytocin cannot be assured since access to sustained cold-chain is unavailable. Regarding the other uterotonics; ergometrine degrades when exposed to heat or light. Misoprostol degrades rapidly when exposed to Moisture. Innovation in the manufacture of carbetocin had meet the stability requirements for hot and humid climates. This study had been accomplished to evaluate the uterotonic effect of carbetocin compared with oxytocin for the prevention of postpartum haemorrhage in emergency caesarean delivery. Looking if carbetocin is superior to oxytocin in term of reduction in the need for additional uterotonic agents or the occurrence of PPH.
The aim of the study is to evaluate haemostasis and fibrinolysis in peripartum of caesarean delivery and the effect of tranexamic acid (TXA) given in prevention of post-partum haemorrhage (PPH).
Excessive bleeding after normal birth or cesarean section is defined as blood loss of 1000 mL or more (clinically estimated) within 24 hours after birth. It occurs in about 5% among postpartum women. Postpartum hemorrhage is a leading cause of morbidity and mortality among women giving birth. Postpartum hemorrhage may lead to hemorrhagic shock, renal failure, respiratory failure, need for surgical intervention, blood transfusion and hysterectomy. The cornerstone of effective treatment is rapid diagnosis and intervention in time. However, in a number of cases there is an underestimation of the volume of blood loss which may lead to delay in diagnosis and treatment. The consequences are even graver in women who delivered by a cesarean section, since unlike a normal birth in which the bleeding is external and visible, the bleeding is usually intra-abdominal, and so the delay in diagnosis may be even longer. The Inferior Vena Cava (IVC) is a flexible blood vessel sensitive to intravascular blood volume, and its diameter varies accordingly. Its diameter reflects the pressure in the right atrium, which is a measure of the cardiac preload. A number of studies have shown that the IVC diameter changes, before the variations in vital and clinical signs. Recently, IVC diameter has been assessed as an assessment of intravenous fluid balance in hemodynamically stable patients with a risk of sub-volume shock. The authors concluded that the IVC measurement is a good noninvasive method, compared to catheter insertion into the right atrium, and it is available as a bedside procedure. In obstetrics the use of IVC to determine blood loos was not widely examined and there is no information regarding the use of IVC diameter as a predictor or as a detection method of postpartum bleeding. In this study the investigators aim to examine the correlation between IVC diameter and the volume of postpartum blood loss.
98 pregnant women attending for CS will be randomized into 2 groups. Rectal misopristol group who will receive 400 microgram misoprostol rectally preoperatively with urinary catheter insertion and intrauterine misopristol group will receive 400 microgram misoprostol intrauterine (200 microgram at each cornu) intraoperatively following the delivery of the placenta. The estimated blood loss for each patient will be measured and data of both groups will be compared.
The Millennium Development Goal of reducing the maternal mortality ratio by 75 % by 2015 will remain beyond our reach unless we prioritize the prevention and treatment of postpartum hemorrhage(PPH) in low-resource countries. Consequently, the administration of uterotonic drugs during cesarean section (CS) and in the third stage of labor for vaginal delivery has become essential to diminish the risk of PPH and improve maternal safety. Oxytocin is regarded as the gold standard uterotonic agent but only has a half-life of 4-10 min; therefore, at cesarean section oxytocin must be administered as a continuous intravenous infusion to attain sustained uterotonic activity throughout the surgical procedure and immediate postpartum period. Misoprostol is a prostaglandin E1 analog proven in several randomized controlled trials to be effective in preventing PPH because of its strong uterotonic effects. In addition, misoprostol is inexpensive, stable at room temperature, and easy to administer. Misoprostol has been broadly studied in the prevention and treatment of PPH after vaginal delivery; however, its use in conjunction with CS has not been investigated as much. The buccal route is recognized as having the greatest benefit due to its rapid uptake, long-acting effect, and greatest bioavailability compared with other routes of misoprostol administration. Carbetocin is a long-acting synthetic analog of oxytocin that can be administered as a single-dose injection; intravenously administered carbetocin has a half-life of approximately 40 min. A single intravenous bolus of carbetocin produces a tetanic uterine contraction within 2 min and persists for an average of 60 min following injection. The aim of this study was to compare the effectiveness of combined buccal misoprostol and IV tranexamic acid (TA)with intravenous carbetocin for prevention of PPH in patients with risk factors during cesarean section.
Excessive bleeding at or after childbirth accounts for about half of all the post-partum maternal deaths in developing countries and is the single most important cause of maternal mortality worldwide. Post-partum hemorrhage (PPH) is the major contributor to maternal mortality worldwide representing at least 25% of the maternal deaths annually. Prevention of PPH has become a global aim to reduce maternal mortality. Uterine atony is the main cause of PPH; therefore, active management of the third stage of labor has emerged as a most actual tool in its prevention. The previous study in Egypt recorded that 88% of deaths from PPH occur within 4 hours of delivery. Tranexamic acid (TA) is an antifibrinolytic agent that blocks the lysine-binding site of plasminogen to fibrin. Misoprostol is effective when given orally, buccal, sublingually, vaginally, or rectally, so it might be used by traditional birth attendants, or self-administered, in cases of home-births occurred without the attendance of health personnel or where women are at most risk for occurrence of severe PPH. So, the current study aims to evaluate the effect of prophylactic oral TA plus buccal misoprostol in the prevention of primary PPH after routine active management of the third stage of labor in women at low risk for uterine atony in comparison with carbetocin and buccal misoprostol alone.
