Filter by:Postpartum hemorrhage (PPH) is a leading cause of maternal mortality and morbidity, and is most commonly caused by poor uterine tone after delivery of the baby and placenta. Currently, a lack of early identification of PPH also results in delayed treatment, with an increase in morbidity. The investigators propose that 2 non-invasive methods may provide monitoring for early and accurate detection of PPH. These methods include shock index (SI) and continuous hemoglobin (Hb) monitoring. SI is defined as heart rate divided by systolic blood pressure, and can be used as a marker to predict the severity of hypovolemic shock. Continuous Hb monitoring can now be done using a non-invasive probe that is placed on the patient's finger. It provides real-time Hb values, rather than having to draw blood and wait for a lab test. The investigators hypothesize that SI will have a stronger association with postpartum blood loss than Hb variation.
The aim is to assess the impact of tranexamic acid (TXA) for preventing postpartum hemorrhage (PPH) following a cesarean section (CS).
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.
The aim of this study is to compare the effectiveness of intraumbilical oxytocin and placental cord drainage in the management of third stage of labor. Does the use of intraumbilical vein oxytocin injection or the use of Placental cord drainage can cause a reduction of blood loss, Hb level drop, the length of the third stage of labor and the incidence of manual removal of the retained placenta during the third stage of labor in pregnant women after delivery of the infant?
postpartum hemorrhage (PPT) represents one of the major causes of maternal mortality . Tranexamic acid is used in many studies in management of PPH in combination with ecobolics. this study aims to evaluate the possible value of the use of tranexamic acid in prevention of postpartum hemorrhage .
Cesarean delivery is defined as fetal birth through incisions in the abdominal wall and the uterine wall. This definition does not include removal of the fetus from the abdominal cavity in the case of uterine rupture or in the case of an abdominal pregnancy The guidelines of the Royal College of Obstetricians and Gynaecologists on caesarean section recommend a slow intravenous bolus dose of 5 IU of oxytocin after delivery of the infant. Intravenous oxytocin has a short half life (4-10 minutes); therefore the potential advantage of an oxytocin infusion at caesarean section is in maintaining uterine contractility throughout the surgical procedure and immediate postpartum period, when most primary haemorrhage occurs
Hemorrhage remains the leading cause of maternal death worldwide. Tranexamic acid has been shown to reduce rates of hemorrhage when given prophylactically prior to cesarean delivery. It has also been shown to be an effective treatment in response to hemorrhage after a vaginal delivery. The aim of this study is to assess the impact of TXA on hemorrhage rates when given prophylactically prior to all deliveries.
Insufficient uterine tone resulting in atony can potentiate hemorrhage and adverse outcomes for the parturient. Oxytocin is the first pharmacologic agent used, followed by methylergonovine, carboprost, and misoprostol. The American Congress of Obstetricians and Gynecologists (ACOG) recommends the sequential use of oxytocin, followed by methylergonovine, carboprost, misoprostol, then surgical intervention for cases of refractory uterine atony. Many studies have examined the effect and dosage of intravenous uterotonics, including oxytocin. Although there are anecdotal reports of using intravenous bolus or rapid infusion of methylergonovine, no randomized trial has compared efficacy and side effects of these two routes of administration. Investigators hypothesize that intravenous methylergonovine reduces the time to adequate uterine tone (the tone at which the uterus is adequately contracted to prevent atony after delivery of neonate), decreases the total dose of methylergonovine to contract the uterus, and therefore produces fewer side effects of hypertension, nausea, and vomiting. Reducing the time to achieve adequate uterine tone is likely to decrease postpartum hemorrhage.
Postpartum hemorrhage is a significant contributor to maternal morbidity and mortality and is worldwide. TXA has recently been proven to reduce mortality when given to women in setting of diagnosed PPH. US obstetricians and anesthesiologists are hesitant to use TXA in the peripartum period especially for prevention of PPH due to uncertainty of an optimal dose and safety profile. The purpose of this study is to characterize the pharmacokinetics of TXA when given prophylactically at time of delivery. In addition investigators will determine the pharmacodynamics of TXA in the peripartum period.
The study aims are to evaluate the impact of supportive follow-up strategies for a novel twinned training and capacity-sustaining program among frontline health workers (providers) attending facility-based births in remote and district level health facilities in Uganda. The program is designed to improve provider competencies, provider performance and health outcomes among women giving birth and newborns.
