Filter by:The objective of this study is to compare the effectiveness and safety of carbetocin vs. oxytocin plus sublingual misoprostol in the management of atonic postpartum hemorrhage (PPH)after vaginal delivery.
The aim of the study is to evaluate the effect of oral tranexamic acid plus, sublingual misoprostol in the management of atonic postpartum hemorrhage (PPH) after vaginal delivery
Postpartum hemorrhage (PPH) accounts for 20-25 percent of maternal deaths worldwide. Tranexamic Acid (TXA) is an antifibrinolytic agent that has been shown to reduce the estimated blood loss after delivery and is recommended by the World Health Organization for PPH treatment. However, dosing in studies ranges from 0.5g to 4g and the optimal dose of TXA in the pregnant population has not been established. Further, the effect of TXA on global coagulation assessed by rotational thromboelastometry (ROTEM®) has not been elucidated. The primary aim of this study is to evaluate the pharmacokinetics (PK) and pharmacodynamics (PD) of TXA administered after delivery in patients at risk for PPH.
The participants will be randomized into an oxytocin plus uterine massage group and an oxytocin-only group in the third stage of the labor. Women allocated to the uterine massage group will be provided with trans-abdominal uterine massage starting promptly after delivery of the fetus until delivery of the placenta. The amount of postpartum hemorrhage and placental delivery time will be recorded and compared between the groups.
The investigators prepared a novel study of tranexamic acid (TXA) designed to estimate the quantity of blood loss in women undergoing elective repeat cesarean deliveries. This is the first trial to utilize a prophylactic dose of TXA prior to incision followed by a subsequent prophylactic dose at placental delivery in obstetric patients undergoing scheduled cesareans. The purpose of this study is to quantify blood loss during uncomplicated repeat cesarean deliveries with and without TXA. The central hypothesis is that TXA administration reduces blood loss and fibrinolysis in women undergoing repeat cesarean sections.
Poor uterine tone after the birth of a baby may cause serious bleeding (called postpartum hemorrhage or PPH). This is a major cause of maternal death worldwide. In the developed world the cesarean section rate is increasing. There are two modalities for anesthesia for cesarean section; general and regional (eg. spinal anesthetic). General anesthesia has been associated with increased blood loss compared to regional and the reasons for this may be multifactorial. Some of the anesthesia gases have been studied and there is laboratory evidence to suggest that these gases may reduce the tone of the uterus and therefore cause increased blood loss due to poor uterine tone. To date there has been little study on the intravenous anesthesia agents. These agents are usually administered to anaesthetise the patient at the start of surgery (induction of anesthesia), however they can also be used instead of the gases to keep the patient asleep using a 'total intravenous anesthesia' technique. Laboratory work in rats has suggested that high doses of these intravenous drugs might reduce uterine tone, thus increasing the risk of blood loss. Interestingly, at low doses one of these drugs (ketamine) may actually increase uterine tone. Only one of these drugs has been studied in human uterine tissue. The investigators plan to compare three anaesthesia induction agents on human uterine tissue under physiological conditions in the laboratory. This study will be the first to compare these three drugs on human tissue. The investigators plan to determine the impact of these drugs on spontaneous uterine contractility and also contractilty induced by oxytocin, which is the drug most commonly administered to help contract the uterus after birth. This is important as it will help inform anesthesiologists as to the best drug to use depending on the clinical circumstance. The investigators hypothesize that the intravenous induction agents will cause a dose dependent decrease in spontaneous uterine contractility, similar to what has been described in the rat model. The investigators also expect that exposure to high concentrations of intravenous anesthesia induction agents will cause a blunted contractile response to oxytocin.
Postpartum hemorrhage (PPH) remains one of the leading causes of maternal mortality and morbidity worldwide, including in France, where it accounts for approximately 20% of maternal mortality. Although numerous studies have examined immediate PPH, very few have explored secondary (also called late) PPH. Moreover, there are no guidelines in France for the management of secondary PPH. Its frequency appears to vary from 0.2% to 3.0% of deliveries. It is, however, difficult to estimate because only severe secondary PPH will lead to hospitalization and the rare publications concern single-center studies. The cause of these secondary hemorrhages is often unknown, due to the lack of routine uterine aspiration. Nonetheless, this aspiration is not always medically justified. The principal objective of this study is thus to establish the incidence of severe late PPH in the general population.
Introduction: Obstetric hemorrhage is the most feared complication that can occur during childbirth and continues to be the leading cause of death in pregnant women worldwide, about 7 women die every hour in the world. This is defined as an accumulated loss of blood of more than 1000 mL with signs and symptoms of hypovolemia within 24 hours of the birth process. The main objective of resuscitation in these patients is precisely to reduce the deleterious effects that are generated from the depletion of volume and the altered capacity of oxygen transport. The current debate focuses on the safety and efficacy of each particular liquid during resuscitation and on improving long-term patient outcomes. At present, there is no conclusive evidence on the impact at the level of acid-base status, hydroelectrolytic balance and potential kidney injury with respect to the use of balanced solutions such as Plasma-Lyte or Ringer's Lactate. Objective: To determine the differences in the volume of liquids and blood products required with the use of balanced crystalloids (Ringer's Lactate or Plasma-Lyte) in patients with obstetric hemorrhage in the Hospital Universitario Fundación Santa Fe de Bogotá during 2018 - 2019. Design, Materials, and methods: Historical cohort analytical study. All patients over 18 years of age who present an obstetric hemorrhage defined as bleeding> 1000 mL or less associated with signs or symptoms of hemodynamic instability will be included. The most important exclusion criterion is the presence of active infection at the time of the event. Patients will be divided into two groups, those who underwent hydroelectrolytic resuscitation with Plasma-Lyte and Ringer Lactate. Results and conclusions With this study, we intend to describe the differences in the base acid status measured by arterial gases in patients with obstetric hemorrhage. The aim is to find a relationship between the different groups with clinical outcomes, such as days of ICU stay and hospitalization, blood transfusion requirement, electrolyte disorders, acute kidney injury and survival.
Cesarean delivery has become the most common surgical procedure in the US. Non-steroidal anti-inflammatory drugs (NSAIDs) have been shown to improve the quality of post-cesarean analgesia and markedly reduce opioid consumption. The effect of NSAIDs on healthy volunteers results in inhibition of platelet aggregation and prolonged bleeding time. However, in the obstetric population, the presence and degree of platelet inhibition after NSAID exposure is less clear. The investigators plan to use Platelet Aggregometry and Thromboelastography (TEG) to evaluate the effect of ketorolac on platelets.
Study aim to evaluate the efficacy and safety of a novel technique of UTERINE COOLING during repeated cesarean section (CS) in reducing blood loss, and record any adverse effects following it.
