View clinical trials related to Upper Gastrointestinal Bleeding.
Filter by:Conventional supplemental oxygen therapy (COT) during upper gastrointestinal (UGI) endoscopy via nasal catheter is considered the standard practice in maintenance of oxygenation and prevention of hypoxia. However, it is still unclear if this oxygen delivery method is optimal in a prolonged (more than 15 minutes) procedure in patients admitted to the ICU. Because of shortage of data in this concern, this prospective, randomized, controlled clinical trial study will aim to evaluate and compare the efficacy of high-flow nasal cannula (HFNC) oxygen therapy versus COT in patients who will undergo prolonged either diagnostic or therapeutic UGI endoscopy in the intensive care unit (ICU) .
BACKGROUND: Data on the awareness of the need to evaluate iron status and IDA prevalence in acute UGIB are limited. OBJECTIVES: This study aimed to investigate the rate of evaluation of iron status and prevalence of iron deficiency anemia (IDA) and the associated factors in patients with anemia hospitalized for acute upper gastrointestinal bleeding (UGIB).
A prospective, randomized, double-blind study will be conducted, including all patients with upper gastrointestinal bleeding, defined as vomiting blood or black bowel movements, within 12 hours prior to admission. Patients will be randomized to receive intravenous metoclopramide 20 mg or placebo, a placebo is a look-alike substance that contains no active drug. Then endoscopy will be performed in the following 120 minutes, evaluating endoscopic visualization with the modified Avgerinos scale.
Controlled-randomized trial evaluating single-use versus reusable gastroscopes in patients with upper gastrointestinal bleeding.
This study will test the hypothesis that azythromycin is efficient and safe in cleansing the upper gastrointestinal tract for endoscopic examination in the case of acute bleeding.
More than 80% of patients with upper gastrointestinal bleeding (UGIB) are hospitalized after their visit to the emergency department (ED). However, some of these hospitalizations do not seem justified. Several clinical scores have been developed to classify patients according to their risk of death or need for therapeutic intervention. The aims of this study are: 1. to describe the characteristics of patients hospitalized for UGIB after their visit to the ED 2. to assess the predictive factors of hospital intervention or death 3. to assess the accuracy of existing prognostic scores to classify patients according their risk of death or need for therapeutic intervention (external validation) and to identify low-risk patients not requiring intervention. 4. Depending on the results, a new score could be derived to identify patients at low risk for intervention or death.
The objective of the investigation is to evaluate the feasibility of detecting blood in healthy volunteers after ingestion of autologous blood mixed with water.
This is a multi-center, prospective, non-randomized, open-label, exploratory clinical investigation performed to evaluate safety and effectiveness of the PillSense System when used for detection of blood in the stomach of patients suspected to have an Upper Gastrointestinal Bleed (UGIB).
This study is a pragmatic cluster randomized controlled trial to evaluate the effectiveness of a clinician-facing implementation strategy on the use of medication optimization (defined as either discontinuation of all antiplatelet therapy or initiation of and adherence to a proton pump inhibitor (PPI)) to reduce upper GI bleeding risk in patients prescribed anticoagulant-antiplatelet therapy (AAT) relative to usual care.
This is a prospective, non-randomized, open-label clinical investigation to evaluate feasibility, effectiveness and safety of the PillSense System, the transit of the PillSense Capsule through the GI tract, patient tolerability of the PillSense Capsule, and blood detection.
