Filter by:Emerging studies have evaluated POCUS (Point of Care Ultrasound) for assessing of gastric content prior to anesthesia to reduce the risk of aspiration and demonstrated that POCUS can accurately identify presence of gastric food or fluid. Despite accumulating studies evaluating POCUS as a diagnostic modality to evaluate for gastric food content prior to anesthesia, there is no study to date that has evaluated the role of POCUS prior to endoscopy among patients with upper GI bleeding. Therefore, this study is to evaluate the diagnostic accuracy of POCUS for retained gastric content prior to endoscopy among patient hospitalized/admitted with upper GI bleeding. This study would take place at Loma Linda University Medical Center. Subjects will be any one who has upper GI bleed required EGD and age of greater than 18 years old. The study will plan for 1 year or reach 50 patients (whichever one comes first). In addition, subjects will be recruited from ED, ICU, Medicine ward by the PI, SubPI, and Collaborators. Subject will received ultrasound up to 6 hours prior the start of endoscopy. The location of Ultrasound would either take place at GI lab prior to scope or at the ward prior to transportation to GI lab or at ICU prior to endoscopy. The ultrasound would focus upper abdomen area and look for antrum. the result will be immediately read before endoscopy and fill out on the sheet before the endoscopy. Patient then proceed with endoscopy. At the end of the scope, the researcher will ask the endoscopist questions regarding how well they could see each part of the stomach in order to complete the study. Both results are compared between US and Endoscopy. Endoscopist is blinded in this study.
As one of the most serious forms of acute stroke, the early mortality rate of intracerebral hemorrhage(ICH) can be as high as 30-40%. The incidence of intracerebral hemorrhage increases with the increase of age. Under the circumstance of the aggravation of aging in China, intracerebral hemorrhage brings a certain burden to families and society. The results of several studies in recent years have failed to provide new therapeutic approaches for the treatment of cerebral hemorrhage. Therefore, novel therapeutic approaches is urgently needed for ICH. Primary and secondary prevention, acute inpatient care, and poststroke rehabilitation are all critical. The objective of this cohort study is to explore factors that might influence the long-term prognosis of patients with ICH and to further identify new potential targets for intervention.
This is a prospective, double-blinded, randomized placebo-controlled trial. The study will be approved by the DUHS institutional review board (IRB) and the trial will be registered at clinical trial registry. After receiving the trial information from the obstetricians during prenatal visits or from the anaesthetists during the systematic anaesthesia visit, or both the prospective women will be invited to participate in the trial. The intervention consists of administration of 1gm of tranexemic acid (TXA) or 10-mls of placebo (normal saline) intravenously, according to the randomization groups slowly over 30-60 sec, within 3 mins of the delivery of baby, after the routine prophylactic uterotonic administration and cord clamping. Administration of the prophylactic uterotonic agent (and TXA or placebo) may be followed by a two-hour oxytocin infusion, in accordance with the hospital policy. All women will be followed up at 48 hours after caeserian delivery. A venous blood sample will be obtained on day-two (D2) after delivery for outcome assessment. Adverse events will be assessed until hospital discharge and by telephone interview at 8 weeks after delivery.
There is need for a whole blood analog for use when banked blood is unavailable or undesirable. In civilian trauma, hemorrhage accounts for ~ 35% of pre-hospital deaths; moreover, ~ 20% of military casualties are in hemorrhagic shock on arrival to field hospitals and an additional 5% require urgent transfusion. A recent review concluded that hemorrhage accounted for ~ 90% of potentially survivable battlefield deaths - lives that could be saved with better hemorrhage control capabilities and improved, field-ready blood, blood components, or blood substitutes. While study of ideal composition for resuscitative fluids is ongoing, it is evident that for those in hemorrhagic shock, volume replenishment alone (without O2 carrying capacity) is insufficient. Alternatively, with massive blood loss or with ongoing bleeding from non-compressible injuries, resuscitation with an O2 carrier alone may be complicated by acquired coagulopathy (either dilutional or trauma-induced). Development of a balanced resuscitation fluid that treats both shock and coagulopathy (comprising a field-deployable O2 carrier with lyophilized humoral hemostatic components and platelets) is essential to allow on-scene treatment during the critical 'golden-hours' after injury. As such, the whole blood analog described herein could be this product, thus transforming care in both civilian and military settings.The scientific purpose of this study is to develop a combined whole blood substitute from individual artificial prototypes that have been separately developed for each blood component (i.e., combining an artificial oxygen carrier, with an artificial plasma analogue and an artificial platelet analogue). Together, these combined components will recapitulate the composition and performance of natural whole blood. Blending and combination experiments of the individual artificial prototypes will be performed to test compatibility and optimize efficacy. State of the art in vitro (bench top) assays will be performed to assess physicochemical and functional performance (hemodynamics, oxygen delivery, hemostasis), with data being compared to experiments performed on fresh and stored whole blood.
The purpose of this study is to test whether prophylactic application of haemostatic gel will reduce the rate of clinically significant bleeding requiring intervention (such as blood transfusion, admission to hospital, other blood products) following endoscopic resection of advanced duodenal neoplasia compared to standard therapy.
The goal of this clinical trial is to test if metoclopramide can improve effectiveness of endoscopic intervention in upper gastrointestinal (GI) bleeds. The main questions the investigators hope to answer is Does metoclopramide lessen the need for repeat endoscopy, interventional radiology intervention or surgery in cases of upper GI bleed? Does metoclopramide improve visibility of the GI walls in cases of upper GI bleed?
Up-to-date evidence suggests that blood transfusion initiated as early as possible reduces the likelihood of death from hemorrhagic shock, and the sooner replacement therapy with blood products is initiated, the greater the effect on mortality. Typically, the patient is transfused with one to two units of O RhD (Rh blood group D antigen) negative packed red blood cells (PRBC). Hemostasis accelerating medicines (dry plasma, tranexamic acid, calcium, fibrinogen) as well as crystalloids are also often given. Finnish Red Cross Blood Service is validating cold stored, 0 RhD positive, male donor, leucoreduced, platelet sparing, low blood group ABO antibody titer whole blood product (LTOWB). For this prospective, open, non-randomized clinical study LTOWB will be used in three prehospital emergency medical services that currently use most of prehospital blood products in Finland, while other participating prehospital emergency medical service bases provide controls. Blood transfusions will be given for clinical indication only. The primary goal is to introduce LTOWB and to analyze its feasibility in Finnish prehospital emergency medical service. Study also aims to prove safety of LTOWB, and to analyze coagulation properties of LTOWB compared to currently prehospitally used PRBC transfusions.
Tractional retinal detachment (TRD) that involves the macula and non-clearing vitreous hemorrhage are the main causes of permanent vision loss in patients with diabetic retinopathy and requires prompt surgical intervention. Macular peeling is a surgical technique used in many retinal diseases including diabetic retinal detachment. Our purpose is to determine whether retinal microcirculatory changes occur after anatomically successful diabetic vitrectomy, and whether changes in blood flow vary if ILM peeling was done and whether changes in macular perfusion affect the final visual outcome. The aim of this study is to non-invasively evaluate, with optical coherence tomography angiography (OCT-A), the anatomical changes of deep and superficial vascular density in the macula with and without macular peeling in diabetic vitrectomy.
Background Blood transfusions in pregnancy are usually urgent, unpredictable, and occur in otherwise healthy women. There is evidence of increasing rates of maternal red blood cell (RBC) transfusion around childbirth both in Europe and in US. Indeed, they are recorded in approximately 0.4-1.6% of all deliveries. Although obstetric patients use a small proportion of the blood supply overall (3-4%), however over the last years there has been a significant increase (about 30%) in the use of blood and blood products throughout pregnancy. Most available data relate to the peri-partum period, defined as those occurring from 48 hours before delivery onwards. Anemia in pregnancy is associated with increased maternal mortality and fetal intrauterine growth restriction (IUGR). The risk of these adverse effects is proportional to the severity of anemia; for instance, preterm birth and low birth weight rates are particularly high among women with a hemoglobin below 7 g/dL. The presence of anemia in at-term pregnant women is a rather frequent and unrecognized risk factor for peri-partum hemorrhage (PPH) transfusion. In a retrospective investigation, we have calculated that almost 20% of at-term pregnant women show iron deficiency anemia. It has been suggested that reduction of RBC transfusion in the context of PPH may decrease maternal mortality and, at the same time, reduce costs. Patient's Blood Management (PBM) is a well-known strategy based on 1) identification of anemia; 2) reduction of blood loss and 3) reduction of RBC transfusion. In several medical specialties, recommendations based on available evidence highlighted the concept that a restrictive RBC administration is safe and efficacious. Despite the fact that the WHO has recommended PBM early 2010, the majority of hospitals are in need of guidelines to apply PBM in daily practice. Rationale Anemia is a frequent and often unrecognized hallmark of at-term pregnancies. Systematic collection of data on transfusion practice during pregnancy and post-partum period are scarce. The application of PBM in obstetrics is expected to improve pregnancy outcome and optimize resources. Objectives Objectives of the present study are 1. To estimate: frequency of anemia in pregnancy and feto-maternal complications, distribution of haemorrhage aetiologies and transfusion indications. 2. To evaluate associations of these outcomes with gestational age, and transfusion dose.
Uncontrolled hemorrhage within 24 hours after severe trauma is the main cause of death in trauma patients. Hemorrhagic shock may be accompanied by traumatic coagulopathy in the early stages of severe trauma. Among them, the main pathogenesis of traumatic coagulation disorder is tissue injury, hypoperfusion, inflammatory response and acute neurohumoral system activation leading to the activation of endogenous protein C, increased consumption of coagulation factor, loss of coagulation factor caused by massive bleeding, low temperature and other factors aggravate the disorder of coagulation function and cause hyperfibrinolysis. Studies have shown that the fatality rate of patients with severe traumatic coagulopathy is 4-8 times higher than that of patients without coagulopathy. Active and effective injury-controlled resuscitation and surgical treatment, target-oriented supplementation of coagulation substrate and correction of coagulation function are the main measures for high-quality treatment of patients with severe trauma. Therefore, early improvement of coagulation function is the key to improve the comprehensive treatment level of patients with severe trauma. At present, four-factor prothrombin complex (4F-PCC) is a compound preparation containing coagulation factors Ⅱ, VII, IX and X separated from fresh plasma of healthy people. It is used in clinical treatment of patients with coagulation factor deficiency or bleeding complicated by taking anticoagulant drugs to achieve rapid hemostasis effect. However, large-scale, long-term observation of the efficacy and safety of the early application of cluster infusion of 4F-PCC in traumatic massive hemorrhage, correction of cocoagulation dysfunction, and improvement of clinical prognosis has not been proven. This study intends to conduct a clinical intervention study on early bunching and sufficient use of 4F-PCC in patients with severe traumatic massive hemorrhage, and evaluate its efficacy in early use of severe traumatic massive hemorrhage through a randomized controlled and open-label clinical study of multi-center, bunching use of PCC in patients with severe traumatic massive hemorrhage.
