Early TIPS With Polytetrafluoroethylene (PTFE) Covered Stents for Acute Variceal Bleeding in Patients...
Decompensated CirrhosisBleeding VaricesThe purpose of this study is to determine whether early use of transjugular intrahepatic portosystemic shunt (TIPS) with Polytetrafluoroethylene (PTFE) covered stents is able to prolong the survival in patients with advanced cirrhosis and acute variceal bleeding.

Evaluating Perioperative Dexamethasone and the Risk of Bleeding in Tonsillectomy
Post-operative HemorrhageTonsillectomy (removal of the tonsils) is a very common surgery in children. Bleeding after tonsillectomy is one of the risks of this surgery and can be more dangerous in children since they have less blood volume than adults. In order to improve recovery after tonsillectomy, steroids (medication that is a strong anti-inflammatory) are often given during the surgery. Recently, a study showed steroids given at the time of tonsillectomy increase the risk of bleeding significantly over children who did not receive steroids. This finding has raised concerns in the Ear, Nose, and Throat (ENT) community since most ENT's use steroids during tonsillectomy in children. The investigators look to explore this question further. To answer the question of whether perioperative steroid administration significantly affects the rate of post-tonsillectomy bleeding, the investigators propose to test the following hypotheses in a prospective, randomized, blinded placebo-controlled trial: dexamethasone does not cause an increase in post-operative bleeding rate in tonsillectomy.

Anticoagulant After Implantation of Biological Aortic Valve Comparing With Aspirin
ThromboembolismBleedingThe optimal medical strategy for prevention of thromboembolic events after bioprosthetic aorta valve replacement (BAVR) remains controversial. The aim of this trial was to compare warfarin therapy (target INR of 2.0 to 3.0) against aspirin 150mg daily as antithrombotic therapy for the first three months after BAVR with or without concomitant coronary artery bypass grafting (CABG). The aim was to evaluate thromboembolic complications, bleeding complications and death.

Diabetic Retinopathy Vitrectomy Study (DRVS)
Diabetic RetinopathyRetinal Detachment1 moreTo compare two therapies, early vitrectomy and conventional management, for recent severe vitreous hemorrhage secondary to diabetic retinopathy. Conventional management includes vitrectomy if hemorrhage fails to clear during a waiting period of 6 to 12 months or if retinal detachment involving the center of the macula develops at any time. To compare early vitrectomy and conventional management in eyes that have good vision but a poor prognosis because they are threatened with hemorrhage or retinal detachment from very severe proliferative retinopathy. To study the natural history of severe proliferative diabetic retinopathy.

The PPHgb Study: Non-Invasive Hemoglobin Measurement
Postpartum HemorrhageThis project is a prospective observational study aimed to assess the use of non-invasive hemoglobin measurement in anticipating postpartum hemorrhage and predicting estimated blood loss. The non-invasive hemoglobin device is the Radical-7 Pulse CO-Oximeter which is a spectrophotometer manufactured by Masimo, Inc. Participants in the study will be undergoing a cesarean delivery at the George Washington University Hospital and during delivery the patient will wear the device on their fingertip so that hemoglobin measurements can be continuously recorded. No changes from routine medical management will occur during the study.

SMCV Assessment on Brain Swelling in Patients With SAH
AneurysmSubarachnoid Hemorrhage1 moreCerebral swelling is a major complication following aneurysmal subarachnoid hemorrhage.This study is a retrospective cohort aimed to predict the extent of brain swelling. Cerebral venous assessment can identify the risk of brain swelling and improve surgical outcomes.

PCC vs. FFP for Post Cardiopulmonary Bypass Coagulopathy and Bleeding
BleedingBlood Loss4 moreThis will be the first prospective randomized controlled clinical trial directly comparing Prothrombin Complex Concentrate (PCC) Compared to Fresh Frozen Plasma (FFP) for post cardiopulmonary bypass microvascular bleeding and factor-mediated coagulopathy. Is there a difference in bleeding and transfusion requirements in patients received PCC versus FFP?

Pancreatoduodenectomy With or Without Ligamentum Teres Wrap Around Gastroduodenal Artery Stump for...
PancreatoduodenectomyTo investigate, whether a prophylactic wrapping of the gastroduodenal artery stump with the ligamentum teres or falciform hepatic (embryological structures, covered with peritoneum that do not have relevant meaning for adults) can reduce the incidence of arrosion bleeding during surgery. Thus a surgical technique is evaluated prospectively.

Intrauterine Balloon Tamponade in the Management of Postpartum Hemorrhage
Postpartum HemorrhageIntrauterine balloon tamponade in the management of postpartum hemorrhage in the obstetrics emergency ward in menoufiya university hospitals as a low resource setting.Guidelines for the management of postpartum hemorrhage involve a stepwise approach including the exclusion of retained products and genital tract trauma. Uterine atony, which is the most common cause, is dealt with uterine rubbing and various uterotonic agents. Among the new modalities introduced to arrest the bleeding is the uterine tamponade using various balloons and catheters. The condom catheter uses a sterile rubber catheter fitted with a condom for uterine tamponade .
