Active clinical trials for "Hemorrhage"

Bleeding peptic ulcer is a common medical emergency. Endoscopic treatment stops bleeding in those actively bleeding from their peptic ulcers, reduces further bleeding, transfusion, surgery and deaths. After initial endoscopic control of bleeding, approximately 10% of them will develop recurrent bleeding. Mortality rate in this group of patients is at least 4 fold higher. In the few who need surgery, mortality approaches 30%. Prevention of further bleeding is therefore a major treatment objective. Currently the investigators use a high dose infusion of proton pump inhibitor (PPI) for 72 hours to render gastric pH neutral. In a previous randomized trial, the investigators showed that the rate of bleeding in 30 days was around 7% with such an approach. In a small subgroup of high risk patients defined by presentation with shock and ulcers > 2 cm in size, 1 in 6 would re-bleed. An alternate strategy is to select those at especially high risk of further bleeding and repeat endoscopic treatment the next morning. The investigators have shown that persistence of major bleeding stigmata, i.e. a visible vessel, during a second endoscopy predicts further bleeding. It is therefore logical that by repeating endoscopic treatment the next morning, the investigators can prevent further bleeding and possibly surgery and deaths. The current study proposes to develop a score to identify those at risk of further bleeding after endoscopy. The investigators used a historical cohort with carefully collected clinical data to derive a risk score. In this derivation phase of 939 patients, the investigators have developed a 9 point risk score which consists of the following parameters (Age>60, Male sex, ulcer>2cm, posterior bulbar in location, spurting or Forrest Ia bleeding and admission hemoglobin of < 8 g/dl). Using AUROC and Youden J statistics, a score of 5 or above has been shown to highly predictive of further bleeding. The score will then be validated in a prospective cohort of patients with bleeding peptic ulcers. In the final phase of this study, the investigators propose a randomized controlled trial to test the hypothesis that a second look endoscopy with treatment in selected high risk patients can further reduce bleeding and improve their outcomes. After endoscopic hemostasis to their bleeding peptic ulcers, patients are risk stratified based on the score. Those with a score of 5 or more are randomized to receive the standard treatment (a high dose PPI infusion) or a second look endoscopy with treatment in addition to PPI infusion. The primary outcome to the trial is further significant clinical bleeding.

Gastrointestinal bleeding (GIB) is one of the most common conditions in the emergency department. Upper GIB is a major problem that has been decreasing over the past 20 years but still has high mortality rate. GIB usually manifests as hematemesis (vomiting of blood or coffee-ground-like material), melena (black or tarry stools), and hematochezia. UGIB appears as hematemesis in 40%-50%, and as melena or hematochezia in 90%-98%,However, patients with LGIB typically present with hematochezia, but right-sided colonic bleeding or small bowel bleeding may show as melena. Endoscopy is the standard of care in the diagnosis and treatment of UGIB. It helps to identify the source of bleeding, establish the underlying etiology ,achieve hemostasis and provide prognostic information to predict the risk of rebleeding causes of UGIB are broadly divided into variceal and nonvariceal (peptic ulcer disease, reflux esophagitis, gastroduodenal erosions, tumors, vascular ectasia, etc. EGD is the diagnostic modality of choice for UGIB with more sophisticated investigations such as computed tomographic angiography and capsule endoscopy being rarely indicated where endoscopy is inconclusive .The primary diagnostic test for upper GI bleed workup is endoscopy. Sensitivity of 92 % - 98 % and specificity of 30 % - 100 % is present for endoscopy for the diagnosis of upper GI bleed. Severity scoring system like Rockall's score, helps to identify the patients who are at higher risk for rebleed and mortality. Lower gastrointestinal ( GI ) haemorrhage is defined as bleeding distal to the ligament of Treitz. Most of the pathological lesions and haemorrhage in the lower GI tract are usually located in the rectum , sigmoid and left sided colon.It is usually suspected when patients complain of haematochezia (passage of frank bright red blood) or bloody diarrhea.Most of the bleeding from the lower GI tract stops spontaneously and patients usually have favorable outcomes compared to upper GI haemorrhage. However, morbidity and mortality tend to increase in older patients and with other pre existing co morbidities.

The aim of this study is to evaluate the impact of a rotational thromboelastometry (ROTEM®)-based transfusion protocol during postpartum hemorrhage (PPH) after vaginal or cesarean delivery. Maternal transfusion requirement, quantitative blood loss (QBL), need for intensive care unit (ICU) admission, and length of hospital stay will be evaluated. The utilization of ROTEM® for transfusion management will identify patients who develop early coagulation changes such as hypofibrinogenemia or disseminated intravascular coagulation. Our hypothesis is that earlier identification and directed therapy of such coagulation changes will lower overall transfusion requirement (packed red blood cells, fresh frozen plasma, fibrinogen concentrate, cryoprecipitate, or other product), reduce the need for ICU admission, and shorten length of hospital stay. A cost analysis will be performed.

To evaluate the feasibility of performing a cervical sympathetic block in patients with severe cerebral vasospasm involving the anterior cerebral circulation following aneurysmal SAH.

When fever is present in patients with stroke, traumatic brain injury (TBI), or brain hemorrhage, it has been associated with worse outcomes including larger areas of tissue death, increased length of stay, worse degree of coma, lower ability to function, and higher mortality. Both adult and pediatric TBI national guidelines state that maintenance of normal body temperature should be a standard of care. However, no further standards or options are presented to specifically guide practice. The current ischemic stroke guidelines state that fever should be treated with fever-reducing agents and offer "cooling devices" as an option but do not provide specifics to guide practice. Over 50% of patients in the Neurosurgical Intensive Care Unit (ICU) at Harborview Medical Center develop fever during the course of their stay. With elevated temperatures the body consumes more oxygen than if the temperature was normal, causing less oxygen to be available to the brain. This may lead to injury of the brain cells and a diminished capacity for healing. Thus, temperature management in neurologically vulnerable patients is both a prevalent and problematic challenge. Based on this information the goal of the present proposal is to evaluate if 1) A standardized, step-wise approach to temperature management using a Normothermia Protocol is successful in achieving and maintaining normal temperature in Neurosurgical ICU patients; and 2) If maintenance of normal temperature will be associated with fewer episodes of diminished responsiveness in their neurological exams as evidenced by a measure of depth of coma, as measured by the Glasgow Coma Score (GCS) compared to a control group treated according to usual care.

The occurence of a minor craniocerebral trauma in patients receiving vitamine K antagonist treatment leads to a high risk of bleeding. Current guidelines recommend to perform a CT scan, and, in case of intracranial bleeding, to reverse anticoagulation with concomitant administration of prothrombin complex concentrates (PCCs) and vitamin K. However, even if a reversion is performed, the prognostic of post-traumatic intracranial bleeding remain bad. The investigators hypothesize that, for patients admitted in an emergency department after a minor head trauma and receiving anticoagulant treatment, a systematic preventive reversion with PCCs can lead to a significant reduction of intracranial haemorrhage and can also improve the neurological prognostic of patients versus the current strategy. PREVACT will test this hypothesis, in an open label, randomized, multicentre, clinical trial involving 400 patients.

Patients presenting to the emergency room with upper gastrointestinal bleeding and a Glasgow Blatchford score of zero will be randomly assigned to further care in the inpatient vs. outpatient setting. The hypothesis of this study is that patients who are managed as outpatients will require interventions at a rate not higher than those managed as inpatients and will have lower direct healthcare costs.

The aim of study is to evaluate whether Doppler ultrasound can accurately identify patients who are at risk of recurrent bleeding, who will require endoscopic therapy, and who will fail endoscopic therapy.

A study of the effect of three different nonsurgical methods for management of abnormal uterine bleeding caused by cesarean scar niche. The study was conducted at the Obstetrics and Gynaecology department of the Saudi German Hospital in Madinah- Saudi Arabia, during the period between March 2019 to October 2022. The study protocol was in accordance with the Helsinki declaration 1964 and the later amendments. A prospective approval was granted by the human research ethics committee of the hospital and the study participants have signed an informed consent.

Carbetocin is an oxytocin receptor agonist that selectively binds to receptors in the smooth muscle of the uterus, stimulates rhythmic contractions of the uterus, increases the frequency of existing contractions, and raises the tone of the uterine musculature. Carbetocin is approved in >100 countries for the prevention of postpartum hemorrhage due to uterine atony in women following cesarean or vaginal delivery. Per regulatory requirements, the current trial will evaluate the effects of high clinical exposure of carbetocin on the QT interval corrected for heart rate (QTc) as measured by ECG in healthy men and women.
