Filter by:The purpose of this study is to compare Floseal to our standard of care (SOC) to decrease intraoperative and immediate post-operative bleeding.
Rotational thromboelastometry (ROTEM) is reliable point of care management of coagulation disorder undergoing surgery. Recently, there are some reports about prediction of perioperative bleeding using ROTEM. But, the effectiveness of ROTEM for predict bleeding and improve outcomes is still debate. In this retrospective study, the investigators will compare immediate postoperative bleeding with ROTEM parameters using a Gray zone approach, and access the reliability of ROTEM for prediction of bleeding after cardiac surgery.
Recently, a clinical trial showed that the use of lumbar drains compared to ventricular drain in patients suffering from subarachnoid hemorrhage resulted in less delayed ischemic neurological deficits but failed to show a clinical benefit after 6 months. The underlying assumption was, that the cerebrospinal fluid (CSF) obtained from lumbar drains has a higher concentration of blood than CSF from lumbar drains. The investigators decided to test this assumption. In this study, the investigators will randomize patients to either placement of a ventricular or a lumbar drain and analyze the CSF drainage on a daily basis.
Postpartum hemorrhage is one of the most common causes of maternal mortality and serious maternal morbidity, especially in the developing world. In India, hemorrhage is a major cause of maternal mortality: A study by the Register General in 1993 showed that 23 percent of all maternal deaths in rural areas were caused by hemorrhage (Sibley, 2005). The measurement of postpartum blood loss and identification of postpartum hemorrhage are important measures in efforts to prevent and treat postpartum hemorrhage. In recent years, researchers have employed several different methods to measure blood loss in hospital and community-based birth settings. Although research has demonstrated that these laboratory measures are more accurate then visual estimation techniques, no studies have explicitly documented the systematic differences (if any) among different collection modalities. Moreover, only a few of these studies have correlated measured blood loss with changes in hemoglobin levels experienced between the antepartum and postpartum period. The aim of this study is to compare variations in the measurement of blood loss obtained using two popular measurement methods: the Excellent BRASSS-V Drape™ and a modified version of the blood collection method developed by the World Health Organization (WHO).
The main objective is to evaluate the efficacy and safety of topical Tranexamic Acid (TA) to reduce the blood transfusion rate in total knee arthroplasty. The secondary endpoints are to estimate the visible blood loss at 24 hours after surgery, and invisible blood loss through serial counting of Hb/Htc. Methodology. TRANEX1 is a phase III, unicentric, controlled, randomized, double blind clinical trial that compare efficacy and safety of topical TA versus intravenous TA in a multimodal protocol, with no-inferiority criteria(n=79).
This study will evaluate the hypothesis that the administration of intraventricular tPA reduces the rates of cerebral vasospasm and ventriculoperitoneal shunt-dependent hydrocephalus in patients with aneurysmal subarachnoid hemorrhage.
Blood loss in hepatic surgery is the main factor of postoperative morbidity. The use of the most effective possible tool for hemostasis allows a bleeding decrease during liver transection and thus could reduce postoperative morbidity. In the past decade, the improvement of techniques of transection of the hepatic parenchyma was one of the most important factors to ensure the hepatectomy safety. But the clinical performances of these technological innovations (ultrasound dissectors, monopolar radiofrequency probes and dissection devices using pressurized water) remain still unclear. The medical device of hemostasis Aquamantys® (Salient company, Innopath) use the technology of "transcollation" combining a source of radiofrequency associated with a conductive liquid (NaCl 0.9% solution). The system consists of a specific generator (Aquamantys Pump Generator®) and single-use probes (Aquamantys 2.3 BipolarSealer®). The energy of radiofrequency is delivered by two bipolar electrodes. The innovative aspect of this device consists in maintaining the tissue to a temperature of 100°C, while using a conductive liquid which acts as process of cooling and avoids the drying out of tissues, smoke, risks of electric arc and overheating met with conventional electrosurgery. This device allows the coagulation of blood vessels but also bile ducts. The Aquamantys® system could decrease the postoperative morbidity and mortality due to a decrease of blood loss and biliary leak. These clinical benefits could be translated by an improvement of the direct and indirect costs associated to the surgery. However the Aquamantys® technology has not been scientifically validated in the context of the hepatic surgery, and this technology is expensive due to the purchase of single-use bipolar probes (Aquamantys 2.3 BipolarSealer®) and to the investment in a generator (Aquamantys Pump Generator®). Consequently, it is essential to realize a study measuring the clinical and medical economic impact of the transcollation technology (Aquamantys® device) in the hepatic surgery.
Endoscopic biliary sphincterotomy is a common and important procedure for biliary access and therapy during endoscopic retrograde cholangiopancreatography (ERCP). Bleeding is one of the important complications related to sphincterotomy. This study determines the role of proton pump inhibitor (PPI) in preventing post-sphincterotomy bleeding in patients undergoing ERCP and sphincterotomy.
Lower body negative pressure (LBNP) is a laboratory model used to study hemorrhage in humans. The investigators hypothesize that the physiologic changes that occur with application of LBNP mimic those observed in bleeding and hemodynamically unstable trauma patients, and that LBNP is a truly valid model of human hemorrhage.
