Estimating Blood Loss Using TritonTM in Vaginal Deliveries: A Validation Trial
Post Partum HemorrhageBlood Loss2 moreThis study will be a prospective cohort study. Patients who meet criteria for inclusion in the study will be approached for participation at same day of admission. Written informed consent will be obtained from the patients by the Co-principal investigator and by the study collaborators. If patients agree to participate, a CBC (complete blood count) will be obtained via venous puncture routine in our facility as part of the admission labs which will be around 10 cc of blood. The device will be used during the delivery in laboring room. The device will be used to assess QBL (quantitative blood loss) by the research staff only and results/ QBL assessment will be masked to the clinical team. Unmasking will only occur following study completion with purpose to perform data analysis. Patient management will be according to the clinical team without the knowledge of the QBL. All patients undergo a CBC postpartum as part of post-partum evaluation, this will also be performed by venipuncture where 10 cc of blood will be collected. The drop in Hgb (hemoglobin) between the pre and post partum CBCs will be calculated for each patient. The post-partum CBC will be collected approximately 24-30 hours from delivery as standard in our unit. The blood will be collected from each patient by the nursing staff who are experienced in withdrawing blood. Patients will be divided into quartiles of Hgb. Cases will be those patients whose Hgb is in the upper quartile, while controls will be those patients whose Hgb is in the lower 3 quartiles. We will be comparing visual EBL (estimated blood loss) by standard clinical assessment versus the QBL result from the device between cases and controls. The Triton L&D (labor and delivery) system which comprises of the device, software analysis and staff training will be supplied by the manufacturer free of charge. Research staff will be trained by the manufacturer. We will be offering our skills, fellows, midwifes and residents, who will be collecting data and we will be performing the data analysis. Results will be available to the manufacturer after results are completed. The results of this study will be presented in conferences or published in a peer-review journal. Demographic information will be obtained from the electronic medical record. The data will be kept on a password secured University of Texas Medical Branch (UTMB) computer. An encrypted USB flash drive will be used to transfer data. The data will be identified and linked to the patient using the medical record number. During data analysis, all patient identifiers will be deleted.

Mild Hypothermia During Intracranial Aneurysm Clipping
Subarachnoid HemorrhageAneurysmalThe purpose of this study is to determine whether mild hypothermia causes reduction of vasoconstriction in microcirculation after clipping of aneurysms, and affects the blood flow in small diameter arteries at operating site (ischemia-hyperemia) and occurrence of vasospasms during the period of 14 postoperative days measured by transcranial Doppler.

Prophylactic Antibiotics in Prevention of Spontaneous Bacterial Peritonitis in Compensated Liver...
Liver CirrhosisUpper Gastrointestinal Bleedingtimely short-term antibiotic prophylaxis is an essential step in the management of these patients . Prophylaxis must be instituted as early as variceal hemorrhage is suspected, and timely administration has been associated with a reduced re-bleeding rate and lower mortality . More recently, the American Association for the Study of Liver Diseases (AASLD), the Department of Veterans Affairs (VA), and the American Society for Gastrointestinal Endoscopy (ASGE) recommended antibiotic prophylaxis in all cirrhotic patients with UGIB, regardless of its source (i.e. variceal or non-variceal) or the presence of ascites.

Transient Elastography and Variceal Bleeding
BleedingTransient elastography is a new non-invasive rapid and reproducible method, allowing evaluating liver fibrosis by measurement of liver stiffness. The aim of our study is to evaluate if the liver stiffness can predict the recurrence of upper variceal bleeding in cirrhotic patients hospitalized for variceal rupture.

Effectiveness Study of the BioVac Direct Suction Device in Upper Gastrointestinal Bleeding
Gastrointestinal HemorrhageUpper endoscopy is performed for upper gastrointestinal bleeding (bleeding in the esophagus, stomach, or part of the duodenum) to identify and potentially treat the cause of bleeding. However, blood clots often make visualization difficult during endoscopy. The current practice is to try to wash off and suction up these blood clots with the endoscope. However, this is often not successful due to blood clots blocking the suction channel. A new device has been approved by Health Canada that attaches to the endoscope and helps prevent blockage. It is believed that this device will help doctors suck out blood clots and potentially improve visualization, identification of the cause of bleeding, and possibly health outcomes, although this has never been proven. The purpose of the this clinical trial is to test whether the device works and whether it can help patients with this type of bleeding.

Evaluation of Recombinant Factor VIIa in Patients With Severe Bleeding Due to Trauma
Acquired Bleeding DisorderTraumaThis trial is conducted in the United States of America (USA). The purpose of this study is to evaluate the treatment of Recombinant Faction VIIa in Patients with Severe Bleeding Due to Trauma Please note that this trial and trial F7TRAUMA-1711 (NCT00184548) have been merged.

Detection of Upper Gastrointestinal (GI) Bleeding Using a Novel Bleeding Sensor Capsule -A Pilot...
Upper Gastrointestinal BleedingThis 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).
