Comparison of IV Ergonovine With IM Carboprost, With Oxytocin IV, During Cesarean Section for Failure...

Postpartum Hemorrhage

Patients having Cesarean section after they have been in labor for many hours bleed much more, in average twice as much, as compared with patients having an elective Cesarean section. The investigators believe a simple change in practice might contribute to reduce this bleeding. This study will involve the use of oxytocin (also known as syntocinon), ergonovine (also known as ergot) and carboprost (also known as hemabate). Oxytocin is routinely used to help contract the uterus and keep it contracted after the delivery of the baby and placenta, so as to reduce the amount of blood loss. Ergonovine is also given through the intravenous line, while carboprost is given as an injection in the muscle. Although they are not routinely given in every case, these are very frequently given as rescue medications to patients who fail to respond appropriately to oxytocin. This study is designed to determine if ergonovine or carboprost given in association with oxytocin, in a preventive way, after delivery of the baby and placenta, can reduce the amount of blood loss during Cesarean sections following a trial of labour.

the Treatment of Postpartum Hemorrhage Due to Placenta Previa Complete Centralis

Placenta Previa Complete Centralis

Objective: To assess the efficacy of lower uterine compression sutures (involved bilateral uterine artery ligation and compression of the lower uterine segment at the same time with one circular stitch) as a conservative treatment for the treatment of postpartum hemorrhage in women with placenta previa complete centralis. Method: This prospective study of 50 women with postpartum hemorrhage following removal of placenta previa complete centralis during elective cesarean section. All 50 patients will have lower uterine compression sutures (involving bilateral uterine artery ligation and compression of the lower uterine segment at the same time with one circular stitch). All patients will be followed postpartum for evaluation of uterine cavity and menstrual cycles

World Maternal Antifibrinolytic Trial

Postpartum Haemorrhage

The WOMAN trial is a large pragmatic randomised double-blind, placebo controlled trial to quantify the effects of the early administration of tranexamic acid on death, hysterectomy and other relevant outcomes. 20,000 adult women, after delivery who have clinically diagnosed postpartum haemorrhage, are eligible if the responsible doctor is for any reason substantially uncertain whether or not to use an antifibrinolytic agent. Additionally, TWO nested studies will be conducted in a subset of women trial participants. The first nested study (ETAC) aims to evaluate the effect of tranexamic acid (TXA) on markers of coagulation in 400 women randomised to the WOMAN trial. The second nested study (ETAPLAT) aims to evaluate the haemostatic effect and antithrombotic effect of TXA in 128 women randomised to the WOMAN trial.

The Relaxant Effect of Nitroglycerin on Oxytocin Desensitized Human Myometrium

Postpartum Hemorrhage

Oxytocin causes myometrial contraction via the oxytocin receptor (OTR). Desensitization of the OTR after exposure to oxytocin has been demonstrated in previous studies. The resultant need for a higher oxytocin dose to cause adequate uterine contraction in vivo has also been demonstrated in laboring women having received oxytocin for labor augmentation. Achieving rapid uterine relaxation can be invaluable for maternal and fetal wellbeing in some acute obstetric emergency settings. Nitroglycerin has become a commonly used agent for achieving rapid uterine relaxation amongst obstetric anesthesiologists. Previous studies have concluded that oxytocin can be used to re-establish uterine tone following nitroglycerin mediated relaxation. However, no studies to date have looked at the effects of nitroglycerin mediated relaxation of uterine muscle that has undergone oxytocin receptor desensitization. Nor has the response to oxytocin re-exposure and return of contractility in desensitized myometrium (following nitroglycerin) been examined. The investigators hypothesize that nitroglycerin will reduce and inhibit uterine contractions in both oxytocin pre-treated myometrium, as well as untreated myometrium in a dose dependent fashion, but that myometrium that has undergone OTR desensitization will require less nitroglycerin for contractions to abate. The investigators also expect that the dose of oxytocin required to re-establish equivalent contractions will be higher in the myometrial samples which have undergone nitroglycerin mediated relaxation.

Hayman's Haemostatic Suture to Treat Severe Post-partum Haemorrhage

Postpartum Hemorrhage

Post-partum haemorrhage continues to be a leading cause of maternal mortality and morbidity, accounting for more than 125 000 deaths per year across the world. Prompt diagnosis and effective action are the cornerstones of management and are crucial to prevent fatal maternal haemorrhage. Considering that published data are extremely limited, the aim of our study will be to evaluate retrospectively the efficacy of Hayman's Haemostatic Suture for the treatment of resistant post-partum hemorrhage resistant to pharmacological therapy.

Patient Blood Management for Massive Obstetric Hemorrhage

Post Partum HemorrhageFibrinogenolysis; Hemorrhage4 more

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.

Hemostatic Assessment of Postpartum Hemorrhage Using Sonoclot Signature

Postpartum Hemorrhage

Postpartum hemorrhage is the leading cause of maternal morbidity and mortality throughout the world. Rapid diagnosis and early management improve maternal prognosis. Postpartum hemorrhage is defined by a blood loss exceeding 500 ml during the 24 h after delivery. There are many causes of postpartum hemorrhage. Most cases develop from uterine atony, which accounts for 75% of cases. Even though there are risk factors for postpartum hemorrhage, it is still an unpredictable obstetric emergency. Coagulation plays an important role in postpartum hemostasis. Primary and especially secondary coagulation disorders are risk factors for Postpartum hemorrhage. When bleeding occurs, the decrease in fibrinogen levels is the most rapid change observed among markers of coagulation. Recent studies show that fibrinogen concentration during the initial management of Postpartum hemorrhage is the most informative biological marker for the severity of the hemorrhage. Various methods are used to record coagulation profile. One of them is estimation by sonoclot. Viscoelastic hemostatic assays devices (such as sonoclot) have practical advantages as point-of-care devices for monitoring major hemorrhage including a set of parameters that assesses a global coagulation profile like fibrinogen and platelet count. Identification of coagulopathy by viscoelastic point-of-care testing can be helpful in guiding management of Postpartum hemorrhage and preventing severe maternal outcomes.
