Active clinical trials for "Hemorrhage"

Patients with active gastrointestinal bleeding can be included. 5ml of SerasealTM/Fastact (Wortham Laboratories, Chattanooga, USA), a CE-certified medical product for in human intraoperative use as hemostatic agent, is topically applied via catheters to the bleeding site. In group A, Seraseal is applied as initial method for hemostasis. In group B, Seraseal is applied after an initial failure of the institutional standard method. Homeostatic success is determined by 5 min without bleeding at gastrointestinal site. after application of Seraseal.

The main hypothesis of this clinical trial is that the use of intra-articular tranexamic acid and the fibrin glue plus usual hemostasis will reduce at least a 25% the postoperative blood loss with respect to usual hemostasis in patients undergoing subcapital femoral fractures.

Gastro-oesophageal varices (swollen veins in the gullet and stomach) are present in 50% of patients with liver cirrhosis and are its most serious complication as their rupture results in potentially life threatening bleeding. Bleeding from these veins occurs in up to one third of patients with varices. This is associated with 20% mortality at 6 weeks. In the event of bleeding from these veins the current UK guidelines recommend certain drugs followed by early endoscopic treatment with variceal band ligation (rubber bands placed over the veins to stop them bleeding). The use of a shunt inside the liver ("TIPSS" transjugular intrahepatic portosystemic shunt) is largely reserved for cases of uncontrolled bleeding from these swollen veins. A recent randomised multicenter study carried out by Garcia Pagan and colleagues reported improved survival with early TIPSS in patients with bleeding from these swollen veins in advanced liver disease. From these guideline international guidelines now recommend consideration of early TIPSS for all high-risk patients presenting with variceal bleeding. This practice clearly has significant cost implications. To validate the findings a further randomised control trial is needed. This is a multi-center parallel-group randomized controlled trial. Both hospitals taking part in the trial will have a TIPSS service. Patients who consent to enter the trial will be randomized to either: (1) Endoscopic treatment (standard care) or (2) early TIPSS. Potential participants will be all patients with a diagnosis of liver cirrhosis presenting with an acute variceal bleed to a participating hospital who do not fulfill an exclusion criteria. All causes of cirrhosis will be included. Participants will be reviewed during their regular hepatology clinic appointments at their respective hospitals on 3 occasions over a one-year period.

The aim of the study is to test if intracerebral haemorrhage (ICH) patients who have contrast extravasation on computed tomography angiography, the "spot sign", have lower rates of haematoma growth when treated with tranexamic acid within 4.5 hours of stroke onset, compared to placebo.

Currently, there is very little research to identify ways to decrease blood loss during D&E (dilation and evacuation) procedures. The objective is to determine whether routine use of intravenous oxytocin will improve bleeding outcomes at the time of D&E at 18-24-weeks gestation. To evaluate the hypothesis, investigators will perform a randomized, double-blinded, placebo-controlled trial. The patient will be followed until discharged from the postoperative care unit during which time patient satisfaction, pain score and postoperative bleeding will be assessed.

Hysteroscopic endometrial biopsy is usually performed through the classic spoon grasper. Recently, a new hysteroscopic grasper with knurled terminal end and cutting jaws was designed, in order to improve feasibility of the procedure, reduce its duration and the discomfort for the patients. This study aims to compare the outcomes of the three hysteroscopic graspers for endometrial biopsy in post-menopausal patients.

Poor uterine tone after the birth of a baby may cause serious bleeding (called postpartum hemorrhage or PPH). This is a major cause of maternal death worldwide. In the developed world the cesarean section rate is increasing. There are two modalities for anesthesia for cesarean section; general and regional (eg. spinal anesthetic). General anesthesia has been associated with increased blood loss compared to regional and the reasons for this may be multifactorial. Some of the anesthesia gases have been studied and there is laboratory evidence to suggest that these gases may reduce the tone of the uterus and therefore cause increased blood loss due to poor uterine tone. To date there has been little study on the intravenous anesthesia agents. These agents are usually administered to anaesthetise the patient at the start of surgery (induction of anesthesia), however they can also be used instead of the gases to keep the patient asleep using a 'total intravenous anesthesia' technique. Laboratory work in rats has suggested that high doses of these intravenous drugs might reduce uterine tone, thus increasing the risk of blood loss. Interestingly, at low doses one of these drugs (ketamine) may actually increase uterine tone. Only one of these drugs has been studied in human uterine tissue. The investigators plan to compare three anaesthesia induction agents on human uterine tissue under physiological conditions in the laboratory. This study will be the first to compare these three drugs on human tissue. The investigators plan to determine the impact of these drugs on spontaneous uterine contractility and also contractilty induced by oxytocin, which is the drug most commonly administered to help contract the uterus after birth. This is important as it will help inform anesthesiologists as to the best drug to use depending on the clinical circumstance. The investigators hypothesize that the intravenous induction agents will cause a dose dependent decrease in spontaneous uterine contractility, similar to what has been described in the rat model. The investigators also expect that exposure to high concentrations of intravenous anesthesia induction agents will cause a blunted contractile response to oxytocin.

Upper gastrointestinal hemorrhage is a frequently diagnosis in emergency departments. Although new drugs and endoscopic techniques were easily applied in various settings in this condition, the role of local administered therapies such as antifibrinolytic agents remain unclear. The investigators aimed to compare standard therapy (proton pump inhibitors, endoscopic treatments etc.) and standard therapy + local administered tranexamic acid in upper gastrointestinal hemorrhage in a double-blind, randomized trial.

Abnormal uterine bleeding encompasses abnormalities in the regularity, duration of flow, frequency, and/or blood flow volume relative to normal menstruation. Of these menstrual abnormalities, heavy menstrual bleeding (HMB), defined objectively as a blood loss of 80 ml or more per menstrual cycle , which is unrelated to pregnancy or known pelvic or systemic disease.

The aim of this prospective study is to reveal the natural history of symptomatic hemorrhage in adult patients with cerebral cavernous malformation with the goal of informing the treatment plan.
