Active clinical trials for "Postpartum Hemorrhage"

Intramuscular (IM) oxytocin is the gold standard prophylactic therapy for post partum haemorrhage (PPH). However, in resource-poor settings within the developing world, the stability and therefore effectiveness of prophylactic IM oxytocin is diminished by a lack of appropriate refrigeration facilities and availability of trained health care professionals (HCPs) to administer IM injections. This study will be the first investigation of oxytocin in humans via the inhaled (IH) route and is designed to evaluate the safety and tolerability of inhaled oxytocin and the five non-pharmacologically active components in the placebo, and to establish the PK characteristics of up to four fixed escalating doses of inhaled oxytocin. In this single blind ascending dose-escalation study, the systemic exposure from up to four proposed escalating inhaled fixed-dose levels (50 micrograms [mcg], 200 mcg, 400 mcg and 600 mcg) will be compared with the systemic exposure following 10 international units (IU) of IM oxytocin in healthy premenopausal females.. A total of 15 subjects will be enrolled after screening sufficient number of healthy female subjects and the subjects will be assigned to one of the two treatment sequences. The total duration of this study is approximately 20 weeks.

Postpartum hemorrhage (PPH) is the top reason for maternal deaths in China. The four major causes of PPH include uterine atony, genital tract laceration, placenta factors and systemic medical disorders (including inherited and acquired coagulopathy). Management of PPH contains the application of uterotonic agents, using hemostasis agents, transfusion of blood component products, conservative procedures (intrauterine packing or balloon tamponade, compression sutures, vascular ligation and uterine artery embolization using sponges), and even hysterectomy. The Bakri Balloon has attained its efficacy and popularity ever since it was invented by Doctor YN. Bakri. Although it is recommended by many countries as a routine procedure for PPH management, the Bakri Balloon is not yet a first choice in China due to lack in clinical data of preventive usage. The aim of this study is to prove the efficacy and safety of the Bakri Balloon in early management of PPH.

This document defines the Clinical Investigation Protocol for a study designed to determine whether blood loss after spontaneous vaginal delivery is altered by the addition of misoprostol administration to the standard use of intravenous oxytocin after delivery. The protocol is an open-label randomized prospective trial to be carried out at Queens Hospital Center. Blood loss will be measured indirectly by comparing the maternal hemoglobin and hematocrit levels on admission in labor to those obtained within 24 hours after delivery.

The purpose of this study is to compare the ability of a sample of uterine muscle tissue to contract in the presence of various drugs. The drugs studied are typically used to contract the uterus when a pregnant patient continues to bleed after delivery. Amongst the uterotonic drugs (used to contract the uterus), namely oxytocin, ergonovine and carboprost, the most effective one to use is not known. The investigators will be testing uterine muscle samples in the presence of these drugs at various concentrations, to see what their contractility measures over time, as compared with a control sample, in which no drugs will be applied.

This study will evaluate side effects after sublingual misoprostol (600 mcg) as a first-line treatment for primary postpartum hemorrhage (PPH) due to suspected uterine atony.

This study compares the effect of starting intravenous oxytocin infusion early before uterine incision versus late after umbilical cord clamping on the blood loss during elective cesarean section

The rates of cesarean deliveries (CD) and postpartum hemorrhage (PPH) are on the rise, with failed induction and augmentation of labor as major contributing factors. Oxytocin is commonly used for labor induction, as well as during the third stage of labor to minimize the risk of primary PPH. At delivery, it is imperative that the uterus responds effectively to parenteral oxytocin. Poor response to oxytocin following delivery is commonly due to prolonged labor with oxytocin augmentation that is known to "desensitize" the myometrium. Despite the option of several second line uterotonic agents, none of them are as effective as oxytocin in controlling PPH. Given that poor uterine muscle contraction is the root cause of both failed induction or augmentation (leading to a CD in labor) and uterine atony (leading to PPH), there is an urgent and clinically important need to investigate novel methods to enhance oxytocin-induced myometrial contractions. Propranolol, a beta adrenergic receptor agonist, has the potential to improve myometrial contractions by virtue of its ability to inhibit catecholamine production. The investigators plan to investigate the effects of propranolol in both naive and desensitized myometrium, in order to better understand its potential role in improving labor induction and reducing the risk of PPH following oxytocin exposure during labor. The investigators hypothesize that propranolol is likely to potentiate the action of oxytocin upon human myometrium, to ultimately help improve the success of labor induction/augmentation and treatment of PPH.

Every six minutes a mother dies from postpartum haemorrhage (PPH) in low-resource countries, in the prime of her life and often leaving behind a young family. In many settings, when a mother dies in childbirth, her infant has less than a 20% chance of surviving past the first month. PPH, defined as a blood loss of more than 500 ml, is the leading cause of maternal death worldwide, accounting for 27% of maternal deaths. The WHO published "Recommendations for the Prevention and Treatment of Postpartum Hemorrhage" in 2012 to provide evidence-informed recommendations for managing PPH. However, adherence to these recommendations is currently limited by a number of challenges. This primary aim of this multi-country, parallel cluster randomised trial with a baseline control phase, along with mixed-methods and health economic evaluations, is to evaluate the implementation of early detection and the use of the World Health Organisation (WHO) MOTIVE 'first response' treatment bundle for postpartum haemorrhage (PPH) on clinical, implementation and resource use outcomes. The investigators will evaluate the implementation through mixed-methods and carry out a health economic evaluation from the public healthcare system perspective.

The study investigators are comparing 2 drugs (oxytocin and carbetocin) at 2 different dosages, to help prevent serious bleeding (hemorrhage) after cesarean deliveries. These drugs are used routinely to help contract the uterus and keep it contracted after the delivery of the baby and placenta; this reduces the amount of blood you might lose. At Mount Sinai Hospital, currently oxytocin is used, but its effect on the uterus is much shorter than that of carbetocin. Internationally, there is no consensus as to what the most effective drug to use is and at which dose. The Society of Obstetricians and Gynaecologists of Canada has recently revised its guidelines to suggest 100 micrograms (mcg) of carbetocin as the drug of choice at elective cesarean section. Guidelines from the United Kingdom and the United States currently suggest oxytocin at various doses as the drug of choice at elective cesarean sections. Previous studies at Mount Sinai Hospital have shown that lower doses of oxytocin, 0.35 International Units (IU), and carbetocin, 20 mcg, may be as effective as the higher recommended doses. The investigators plan to conduct a large study to confirm these findings so that they can use the most appropriate dose in the future. Furthermore, the investigators hope to demonstrate that side effects are lower with the lower dose regimens.

This randomized controlled community-based trial will assess the effectiveness of administration of 800 mcg sublingual misoprostol with standard of care vs. placebo with standard of care for postpartum hemorrhage treatment at the community level, primarily home births attended by primary health care unit (PHU) staff in Etay El Barood and Kafr El Dawar districts (El Beheira governorate), Egypt. Standard of care per national guidelines in this setting is referral to a higher level health facility.
