Active clinical trials for "Hemorrhage"

Post-tonsillectomy hemorrhage (PTH) is a feared complication to tonsillectomy. Tonsillectomy may be performed using different surgical techniques, which include both "cold" and "hot" dissection and hemostasis - but the technique may have a great impact on the risk of PTH. As of today there is no standard on how to perform hemostasis during tonsillectomy in Denmark. The aim of this study is to clarify whether cold dissection with either cold or hot hemostasis during the surgical procedure of tonsillectomy holds the lowest risk of PTH. Secondary objective is to address whether there is a difference in pain perception associated with the two procedures. The null hypothesis is that there is no difference in PTH between cold and hot hemostasis in tonsillectomy.

Aneurysmal subarachnoid hemorrhage (SAH) is a fatal disease with high morbidity and mortality. While the primary injury results from the initial bleeding and cannot be influenced, secondary injury through vasospasms and delayed cerebral ischemia (DCI) during the course of the disease might be a target for intervention in order to improve outcome. To date, beside the aneurysm treatment to prevent re-bleeding and the administration of oral nimodipine, there is no causal therapy available, so that novel treatment concepts are desperately needed. There are strong indications that inflammation contributes to DCI and therefore poor outcome and plays a major role in SAH. Some studies suggest a beneficial effect of anti-inflammatory drugs like glucocorticoids (GC) in SAH patient, but there are no data from randomized controlled trials proving or disproving the beneficial effect of GC, so that current guidelines do not recommend the use of GC in SAH so far. This multi-center trial aims to generate the first confirmatory data in a controlled randomized fashion that dexamethasone (DEX) improves the outcome in a clinically relevant endpoint in SAH patients. Moreover, this trial will generate first data in a secondary analysis, whether the initial inflammatory state of SAH patients defines a subgroup that particularly responds to a treatment with DEX.

The purpose of the present study is to compare the effectiveness and safety of two surgery evacuation methods (endoscopic surgery and suboccipital craniotomy) in the treatment of acute spontaneous cerebellar hemorrhage (SCH). A multi-center randomized control trial will be conducted. Patients with an initial GCS score of 5-14 will be screened and enrolled in the first 24 hours after SCH.

The Study investigates a new product, sFilm-FS, aimed to help controlling body fluid leakage in general surgery procedures, proposing its use as an adjunct to hemostasis and/or sealing.

Randomized comparison within the endoscopic esophageal varices ligation versus non-selective beta-blocker in the primary prevention of esophageal variceal bleeding in patients with HCC.

This multicenter, pragmatic randomized, open-label clinical trial aims to assess whether Tranexamic Acid improves outcomes in adult patients with spontaneous intracerebral haemorrhage. The participants presenting within 4.5 hours of the onset of symptoms of stroke with intracerebral haemorrhage confirmed on Computed Tomography (CT Scan) will be randomized into two groups in a 1:1 ratio using a central online randomization. The treatment arm will consist of giving intravenously 2 grams of Tranexamic Acid in 100 ml 0.9% sodium chloride administered over 45 minutes. Control arm patients will receive standard of care treatment as per the institutional protocol. In both arms, intensive systolic blood pressure reduction to less than 140 mmHg will be done using antihypertensive medications, which has to be achieved within one hour and will be maintained over next seven days. The choice of antihypertensive drug will depend on the clinician's preference. Both groups will have a repeat CT scan after 24 hours to check for any increase in the haematoma volume. Any deterioration in the neurological status will warrant urgent brain imaging. On day 7, the patient will be assessed for their NIHSS score and mRS score. On day 90, quality of life and the functional outcome will be assessed.

Our study aims to evaluate the efficacy of intracapsular injection of Terlipressin versus Carbetocin injection on hemoglobin level in women undergoing abdominal laparoscopic myomectomy. Moreover, to evaluate their efficacy in decreasing blood loss on operative time and to describe the injection sequelae for the same population. This clinical study will be conducted in compliance with the clinical study protocol and applicable regulatory requirements.

Injury is the leading cause of death for people between the ages of 1-44. This is especially true in trauma patients who have bleeding complications. Acute trauma coagulopathy (ATC) is associated with high transfusion requirements, longer ICU stays, and a greater incidence of multi-organ dysfunction. The cause of coagulopathy is multi-factorial. One major driver is acquired fibrinogen deficiency (hypofibrinogenemia). Fibrinogen is critical in clot formation and enhances platelet aggregation. Due to the body's limited reserve, it is the first clotting factor to fall to critical levels during life-threatening bleeding. This can impair coagulation and increases bleeding complications. There are two primary options available for fibrinogen supplementation: Cryoprecipitate- North American standard Fibrinogen Concentrate (FC)- European standard Consumption of coagulation factors, including fibrinogen, is another important component of ATC. To replenish these depleted coagulation factors and improve thrombin generation, two therapies are available: Frozen Plasma (FP)- North American standard Prothrombin Complex Concentrate (PCC)- European standard Strategies for hemorrhage and coagulopathy treatment have changed significantly over the last decade. Prompt hemorrhage control, along with targeted coagulation factor replacement, are emerging as key components of trauma care. Currently, the initiation of a massive hemorrhage protocol (MHP) results in red blood cells (RBCs) and FP transfusions in a 1:1 or 2:1 ratio. Clotting factors are replaced via FP administration. Fibrinogen supplementation is administration after lab verification or at the clinician's discretion. MHP continues until the rate of hemorrhage is under control. FC and PCC have several important advantages over cryoprecipitate and FP but there is a scarcity of data regarding their efficacy and safety of their use in hemorrhaging trauma patients. The FiiRST-2 study aims to understand if early use of FC and PCC in trauma patients at risk of massive hemorrhage will lead to superior patient outcomes. This trial will also provide safety data on early administration of FC and PCC as a first-line hemostatic therapy in trauma care, and its impact on hemostatic and other clinical endpoints.

The problem of delayed bleeding after endoscopic resection is becoming important due to the growing number of indications for anti-aggregation or anticoagulant treatment for cardiovascular reasons in the aging populations. Previous studies have shown that in patients at high risk of bleeding, the use of (PuraStat®), a simple and easily applicable solution, decreases the rate of delayed bleeding by promoting wound healing. Various preventive treatments, such as the prophylactic use of clips, have been tried to prevent the occurrence of delayed bleeding, but to date, no treatment has clearly shown its effectiveness. In addition, preventive hemostasis with clips is difficult and costly. The main objective is to compare the efficacy of PuraStat® to the standard treatment in reducing delayed bleeding after colorectal ESD in patients at high risk of delayed bleeding. The secondary objectives are to compare the same two strategies in terms of effectiveness and side effects. The primary outcome measure is the percentage of delayed bleeding at 30 days after surgery (ESD).

Aneurysmal subarachnoid hemorrhage (aSAH) is a common type of acute hemorrhagic stroke. One of its complications, cerebral vasospasm (CVS), is the main cause of death and disability, with an incidence of up to 30%-90%. Blood and its metabolites are vital reasons for CVS. Normal saline, as an intraoperative irrigation fluid for the surgery of aneurysm clipping, can induce secondary damage to the brain. In this study, a new type of magnesium-rich artificial cerebrospinal fluid (MACSF) has been designed, which has similar ionic concentration, pH value and osmotic pressure compared with the physiological cerebrospinal fluid. It has been confirmed by animal experiments that MACSF can relieve the hyper-responsiveness of cerebral arteries to ET and 5-HT induced by hemorrhagic CSF from patients with aSAH by down-regulating the expression of ETA, contractile ETB and 5-HT1B receptors in the previous research. Therefore, MACSF may have potential effects on preventing and treating CVS. In this study, we plan to apply MACSF as an intraoperative irrigation fluid for the surgery of aneurysm clipping (MACSF group), which is compared with normal saline (historical control group). To evaluate the effects of MACSF on reducing the incidence of CVS and improving the clinical prognosis of patients with aSAH, the occurrence of CVS within 14 days after aneurysm clipping, NIHSS score, as well as mRS scores at 1, 3 and 6 months after aSAH will be recorded and compared. CVS related biomarkers will be used to evaluate the relationship between the occurrence of CVS and the levels of biomarkers in both CSF and blood samples from MACSF group.
