Active clinical trials for "Hemorrhage"

Rotational thromboelastometry (ROTEM) is reliable point of care management of coagulation disorder undergoing surgery. Recently, there are some reports about prediction of perioperative bleeding using ROTEM. But, the effectiveness of ROTEM for predict bleeding and improve outcomes is still debate. In this retrospective study, the investigators will compare immediate postoperative bleeding with ROTEM parameters using a Gray zone approach, and access the reliability of ROTEM for prediction of bleeding after cardiac surgery.

Knee prothesis surgery is responsible of a risk of thrombosis and hemorrhage. To prevent thrombosis, patients have systematic anticoagulation after surgery which are responsible of hemorrhage. A local glue which improve local coagulation and have no impact of thrombosis can be a solution to limit hemorrhage. The purpose of this trial is to study the impact of a biological glue administration on the bleeding loss at five days after a total knee prosthesis surgery operation.

Extensive research has shown that the big event that leads to the initiation of vasospasm is the release of oxyhemoglobin (blood breakdown product).Depletion of NO synthase (19,20,21) was also noted after SAH.CSF is produced from choroid plexus in the ventricle. If the SAH is too dense, the blood in the subarachnoid space will not easy to be washed out.

The objectives of this study is first to asses to what extent the guidelines of the Dutch Society of Obstetrics and Gynaecology (NVOG) and the MOET (Management of Obstetric and Emergencies and Trauma) instructions for haemorrhagia postpartum have been implemented in current care in the Dutch practice. Second to study barriers and facilitators for guideline adherence and to develop and test a tailored implementation strategy, based on these findings.

According to Morgan et. al. (J Neurosurg 101:1026-1029, 2004): bilirubin as a cerebrospinal fluid marker of sentinel subarachnoid hemorrhage: a preliminary report in pigs, we're going to test the hypothesis in the cerebrospinal fluid of spontaneous subarachnoid hemorrhage patients.

To investigate the adjunctive role of "Capsule Endoscope" in continuous endoscopic monitoring and early detection of recurrent ulcer bleeding after endoscopic therapy in patients presenting with bleeding peptic ulcers

Excessive bleeding after normal birth or cesarean section is defined as blood loss of 1000 mL or more (clinically estimated) within 24 hours after birth. It occurs in about 5% among postpartum women. Postpartum hemorrhage is a leading cause of morbidity and mortality among women giving birth. Postpartum hemorrhage may lead to hemorrhagic shock, renal failure, respiratory failure, need for surgical intervention, blood transfusion and hysterectomy. The cornerstone of effective treatment is rapid diagnosis and intervention in time. However, in a number of cases there is an underestimation of the volume of blood loss which may lead to delay in diagnosis and treatment. The consequences are even graver in women who delivered by a cesarean section, since unlike a normal birth in which the bleeding is external and visible, the bleeding is usually intra-abdominal, and so the delay in diagnosis may be even longer. The Inferior Vena Cava (IVC) is a flexible blood vessel sensitive to intravascular blood volume, and its diameter varies accordingly. Its diameter reflects the pressure in the right atrium, which is a measure of the cardiac preload. A number of studies have shown that the IVC diameter changes, before the variations in vital and clinical signs. Recently, IVC diameter has been assessed as an assessment of intravenous fluid balance in hemodynamically stable patients with a risk of sub-volume shock. The authors concluded that the IVC measurement is a good noninvasive method, compared to catheter insertion into the right atrium, and it is available as a bedside procedure. In obstetrics the use of IVC to determine blood loos was not widely examined and there is no information regarding the use of IVC diameter as a predictor or as a detection method of postpartum bleeding. In this study the investigators aim to examine the correlation between IVC diameter and the volume of postpartum blood loss.

To describe the average labor curve and establish new labor progression standards. Cesarean section rates: Based on big data, the investigator will introduce the international advanced Robson class method and identify the appropriate level of cesarean section rate for each type population. Establishment of "Chinese maternal-fetal medical collaboration network" and APP to promote natural childbirth.

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.

The main aim of the biomarkers to predict Hemorrhagic transformation(HT) after endovascular treatment in Acute Ischemic Stroke Patients. The study has three main parts. During the first part, the investigators propose to conduct an enrollment of patients after thrombectomy in acute Ischemic Stroke and healthy controls. Serum biomarkers levels were analyzed (before and after) endovascular treatment patients and controls respectively. During the second part, HT was evaluated and classified on cranial computed tomography and/or MRI post- treatment and was considered as symptomatic HT (sHT) if associated with neurological deterioration. During the third part, the investigators aim to demonstrate the level of biomarkers can significant predict HT and outcomes in stroke patients undergoing revascularization.
