Filter by:Upper Gastrointestinal bleeding (UGIB) is a medical emergency and the most common cause of hospitalization associated with digestive disease. Proper initial resuscitation is the first step in the management of UGIB patients. Today, modern pulmonary ultrasound is used in different clinical settings, such as intensive care, emergency medicine and/or traumatology. In the last years, the use of this has been standardized both in internal medicine and in pulmonary medicine. The primary objective is to describe the findings of pulmonary ultrasound and its relationship with severity in patients with UGIB. The investigators will include all patients with UGIB. A pulmonary and vena cava ultrasound will be performed on admission to the emergency room, 10 minutes prior to endoscopy and 24 hours after having performed the endoscopy. The use of thoracic point-of-care ultrasound (TPOCUS) has been standardized in both internal and pulmonary medicine. There is a concern about the role of TPOCUS useful as a severity prognostic tool in patients with UGIB. The team proposes that TPOCUS is a severity prognostic tool in UGIB patients. Main Outcome: To describe the findings of TPOCUS in patients with variceal and non-variceal UGIB. Secondary Objectives: 1. Correlate the presence of B-type lines on TPOCUS with mean arterial pressure in UGIB patients. 2. Correlate the inferior vena cava diameter with the Model for End-stage Liver Disease scale in UGIB patients. 3. Correlate the inferior vena cava diameter with the 48 hours post-admission mortality of UGIB patients. Authors design a prospective, longitudinal, descriptive study to identify the findings of TPOCUS in patients with variceal and non-variceal UGIB. Patients will be included in the study since May 15th through October 30th 2019, admitted to the University Hospital, "Dr. José E. González", Universidad Autónoma de Nuevo León.
This is an ambispective single-center cohort study of pediatric patients with portal hypertension and esophageal varices. The study was designed to evaluate the efficacy and safety of primary prophylaxis with endoscopic variceal ligation to prevent upper gastrointestinal bleeding compared to non-selected beta-blockers prophylaxis.
Lower gastrointestinal bleeding (LGIB) is a common presentation in the Emergency Room. It can deteriorate into severe adverse event. However some are discharged before these events occur. The Oakland-Jairath score was developed to help determine which patients can be safely discharged and which should be admitted from the ER to the hospital. The score did well in its development, but now needs to be externally validated by other independent cohorts. The limitations of the first study will be addressed in our study. The goal of this study is to perform the first prospective, multi-centered, external validation of the Oakland-Jairath risk score on an independent and diverse population who present to the emergency room with LGIB.
Spontaneous intracerebral hemorrhage (ICH) results from the rupture of small vessels damaged by chronic hypertension, amyloid angiopathy or other disease. Hematoma volume has been demonstrated to be strongly correlated with the severity of white matter injury and conditions in ICH patients. In the past decades, surgical clot evacuation and stereotactic or endoscopic clot aspiration with thrombolytic drugs have been investigated for the treatment of ICH, however, none of them have been demonstrated to be effective. As such, medical management remains the standard of care for most patients with ICH, leading to ICH as the least treatable form of stroke. Remote ischemic conditioning (RIC) has been found to have neuroprotective effects by in patients with ischemic stroke. In addition, animal studies show that RIC is safe in ICH model and it could accelerate the absorption of hematoma. Therefore, the investigators plan to undertake this study to evaluate the safety of RIC in patients with ICH, and planned for future study to determine if treatment with RIC can improve the outcome of patients with ICH. In this study, our main objectives are: 1) to evaluated the safety of RIC, by determining the treatment related adverse events, in patients with ICH; and 2) to determine the preliminary effects of RIC on hematoma absorption and cerebral edema. The investigators hypothesize that RIC is well-tolerated and has minimal serious adverse effects in patients with ICH; and that treatment with RIC will accelerate the absorption of hematoma and improve patients' functional outcomes. Results of this study can potentially bring into account new means to improve the outcomes of ICH patients.
Erythropoietin (EPO) has been shown to be neurotrophic and neuroprotective in several animal models and some clinical studies. Our hypothesis is that EPO could improve long-term neurological outcomes in very preterm infants with intraventricular hemorrhage (IVH). The aim of this study is to evaluate the long-term neuroprotective effect of repeated low-dose EPO (500 U/kg) in very preterm infants with IVH.
This pilot study will evaluate the performance of the Quantra System comprised of the Quantra Hemostasis Analyzer with the QStat Cartridge in trauma patients or patients with OB hemorrhage.
Leptospirosis is a worldwide zoonosis. The mortality of the disease is between 3,6% to 13%, and up to 48% for the severe leptospirosis. Only few studies exist on severe leptospirosis and none major multicentre on leptospirosis in intensive care units in Europe. The investigators conduct a retrospective multi centric study in metropolitan France in order to identify the characteristic, the treatments and the prognostic factors associated with mortality of sever leptospirosis.
Anti-Mullerian hormone (AMH) is a marker for ovarian reserve. There are many studies about AMH changes in ovarian surgery, but little is known for other surgeries. We seek to investigate the hormone variations before and after uterine artey ligation for postpartum hemorrage (PPH)
Postpartum hemorrhage remains a leading cause of maternal morbidity and mortality worldwide, even in high income countries. Uterine atony is estimated to cause 70-80% of postpartum hemorrhage. Prolonged labor and augmented labor are known risk factors for postpartum hemorrhage. In attempts to reduce the incidence of postpartum hemorrhage, particularly in patients with known risks factors, it is essential to optimize preventative practices in order to reduce the rates postpartum hemorrhage. Although oxytocin is considered the first line therapy for preventing and treating uterine atony, early consideration of additional prophylactic uterotonic agents may be indicated in women with prior oxytocin exposure given oxytocin receptor desensitization and down regulation. As such, investigators sought to examine whether multimodal prophylactic uterotonics (standard oxytocin + methylergonovine), in patients who are increased risk of developing postpartum hemorrhage (specifically laboring patients who ultimately require a cesarean section) would benefit from the addition of prophylactic uterotonics. The clinical rational for administration of multimodal prophylactic uterotonics at the time of cesarean delivery in laboring patients is three-fold: to decrease the incidence of uterine atony, to decrease the incidence of postpartum hemorrhage, decrease the number of uterotonics required at the time of cesarean section. The primary outcome will be to evaluate the need for additional uterotonic agents (Methylergonovine, Carboprost, Misoprostol) at the time of delivery. Secondary outcomes will include the incidence of postpartum hemorrhage (quantitative blood loss >1 liter), surgical assessment of uterine tone four minutes following delivery of the placenta, preoperative and postoperative hemoglobin, the need for a blood transfusion, intensive care unit admission, uterine infection (endometritis).
The primary objective is to obtain data to inform the design of a population pharmacokinetic study of oxytocin after administration at CD as per standard institutional practice.
