Filter by:This is a pragmatic, single center, feasibility pilot cluster randomized trial with embedded individual randomization to evaluate implementation strategies to increase the use of evidence-based practices to reduce upper gastrointestinal bleeding risk in patients using combination antithrombotic therapy (including warfarin) and that are managed by the Michigan Medicine anticoagulation monitoring service.
Postpartum haemorrhage (PPH) remains an important cause of maternal morbidity and mortality and it accounts for approximately 25% of all deaths worldwide. Drugs such as oxytocin, carbetocin, misoprostol, prostaglandin F2a and methylergonovine have been tested for bleeding control during and after cesarean section. Oxytocin is the most widely used agent for the prevention of postpartum hemorrhage.The primary aim of this study is to reduce the mean blood loss during cesarean section.In this study, the investigators planned to compare peroperative and postoperative blood loss levels by giving oxytocin alone to the 1st group, oxytocin and intrauterine misoprostol to the 2nd group, and carbetocin to the 3rd group of patients who were randomly divided into 3 groups.In this study, we aimed to compare the efficacy of oxytocin, misoprostol and carbetocin in preventing uterine blood loss during cesarean section.
Covid-19 vaccines offered a good opportunity to counteract the spread of Sars-Cov-2 infection among the general population, reducing significantly both morbidity and mortality. Nevertheless, after the first and second doses of vaccination (regardless of the type of vaccine used) several women required gynaecological visits claiming menstrual Irregularities or abnormal uterine bleeding. Considering this anecdotal evidence, a questionnaire was designed to investigate systematically whether menstrual Irregularities or abnormal uterine bleeding occurred in a significant percentage of women undergoing first and second doses of covid-19 vaccination.
The study will examine the resting energy need (REE) in patients suffering from brain damage. For the measurement of REE will be used a metabolic computer (which with continuous recording of breath-to-breath volume (Vt), respiratory rate (RR) of ventilation per minute volume (MV) ), of inhaled and exhaled gases (O2 and CO2) has the ability to calculate the values of VO2, VCO2 and with the help of equations the values of REE and RQ.
The aim of the study was to evaluate the relationship between superior vena cava (SVC) flow measurements within the first 24 hours of life and development of intraventricular hemorrhage in preterm born infants.
during PCNL; A few milliliters of nor-epinephrine is injected into the intended tract after puncture of pelvicalyceal system and before its dilatation compared to injection of saline (placebo). hemoglobin change & blood loss is estimated and will compared.
Postpartum hemorrhage (PPH) is the leading cause of maternal morbidity and mortality worldwide. Up to 80% of PPH is caused by uterine atony, the failure of the uterine smooth muscle to contract and compress the uterine vasculature after delivery. Laboratory and epidemiological studies show that low extracellular and serum calcium levels, respectively, decrease uterine contractility. A pilot study performed by the investigators supports the hypothesis that intravenous calcium chloride is well tolerated and may have utility in preventing uterine atony. The proposed research will establish the relationship between uterine tone and calcium through a clinical trial with an incorporated pharmacokinetic and pharmacodynamic (PK/PD) study. In a randomized, placebo-controlled, double-blind trial, investigators will establish the effect of 1 gram of intravenous calcium chloride upon quantitative blood loss and uterine tone during cesarean delivery in parturients with high risk of uterine atony. Investigators will concurrently collect serial venous blood samples to measure calcium for PK/PD modeling in this pregnant study cohort. High-quality clinical research and development of novel therapeutics to manage uterine atony are critical to reduce the high maternal morbidity and mortality from PPH.
The quality of the reversion of these serious hemorrhagic accidents under oral anticoagulants depends on the adequate use of reversion products but also on the speed of obtaining hemostasis data allowing to evaluate the effectiveness of this "chemical" hemostasis. . Clot formation can be studied using different visco-elastic methodologies (thromboelastography or thromboelastometry) with a detectable change in clot formation with oral anticoagulants. These techniques have been proven in patients who are often unstable and present with severe trauma with hemorrhagic shock, thus making it possible to guide the transfusion protocol. However, the level of recommendations in these patients, who are often polyhydrated and poly-transfused, is grade 1c due to small-scale studies with difficulty in analyzing the values of the visco-elasticity parameters in these patients. In addition, these methods are little used in current practice because of their difficult reading. The use of visco-elastic methods in patients on oral anticoagulants has been little studied. However, taking an oral anticoagulant mainly causes coagulation disorders. The use of these methods would make it possible to assess the impact of the anticoagulant on hemostasis and to verify the correct reversion of hemostasis parameters. Quantra®, one of the visco-elastic methods, would make it possible to speed up the evaluation in the context of biology relocated to the patient's bed with a simplified reading of the factors involved in the formation of the clot in order to allow an immediate evaluation the quality of the reversion performed which may have an impact on the re-administration of reversion products or even an adaptation of the dose of reversion products according to the initial parameters at the time of severe bleeding before reversion. The objective of this pilot study is to study the metrological evolution, before and after reversion, of the hemostasis parameters evaluated by the Quantra® system from HemoSonics in a patient being his own control in the context of a severe hemorrhage occurring on oral anticoagulants (VKA or DOA).
Subarachnoid hemorrhage (SAH) is the extravasation of blood into the subarachnoid space from traumatic or nontraumatic origin. There is a paucity of data on the burden of SAH in African countries. In this study, we analyzed data from patients in the largest neurovascular center in Senegal to determine the sex- and age-adjusted burden of SAH in Senegal.
To analyze the characteristics, related risk factors, and prognosis of suprachoroidal hemorrhage (SCH) associated with pars plana vitrectomy (PPV).
