Active clinical trials for "Hemorrhage"

Postpartum hemorrhage (PPH) is the leading cause of maternal morbidity and mortality worldwide. Up to 80% of PPH is caused by uterine atony, the failure of the uterine smooth muscle to contract and compress the uterine vasculature after delivery. Laboratory and epidemiological studies show that low extracellular and serum calcium levels, respectively, decrease uterine contractility. A pilot study performed by the investigators supports the hypothesis that intravenous calcium chloride is well tolerated and may have utility in preventing uterine atony. The proposed research will establish the relationship between uterine tone and calcium through a clinical trial with an incorporated pharmacokinetic and pharmacodynamic (PK/PD) study. In a randomized, placebo-controlled, double-blind trial, investigators will establish the effect of 1 gram of intravenous calcium chloride upon quantitative blood loss and uterine tone during cesarean delivery in parturients with high risk of uterine atony. Investigators will concurrently collect serial venous blood samples to measure calcium for PK/PD modeling in this pregnant study cohort. High-quality clinical research and development of novel therapeutics to manage uterine atony are critical to reduce the high maternal morbidity and mortality from PPH.

during PCNL; A few milliliters of nor-epinephrine is injected into the intended tract after puncture of pelvicalyceal system and before its dilatation compared to injection of saline (placebo). hemoglobin change & blood loss is estimated and will compared.

Rationale: The rapidly increasing number of elderly (≥ 65 years old) with traumatic brain injury (TBI) is accompanied by substantial medical and economic consequences. An intracranial hematoma, specifically an acute subdural hematoma (ASDH), is the most common injury in elderly with TBI. The surgical versus conservative treatment of this patient group remains an important clinical and moral dilemma, since it is in most cases unclear which treatment leads to a better outcome for the patient. Current guidelines are not based on high-quality evidence and compliance is low, allowing for large treatment variation in both Belgium and the Netherlands for patients with a traumatic ASDH. In addition, elderly are underrepresented in scientific TBI literature and are therefore not included in current guidelines or prognostic models, leading to major uncertainty in (neurosurgical) decision-making for this group. As participants in two large TBI research projects (CENTER-TBI, Net-QuRe), the investigators observe that the uncertainty regarding treatment of elderly with a traumatic ASDH will not be solved by the current ongoing studies. Therefore, they recognize the necessity of undertaking a prospective, randomized, multicenter trial on the (cost-)effectiveness of early surgical hematoma evacuation versus a conservative treatment in elderly with a traumatic ASDH. Objective: To compare the (cost-)effectiveness of early surgical hematoma evacuation versus a conservative treatment in elderly patients with a traumatic ASDH. Study design: A prospective, pragmatic, multicenter, randomized controlled trial (RCT). Study population: Patients ≥ 65 years with at first presentation a GCS ≥ 9 and a traumatic ASDH >10 mm or a traumatic ASDH <10 mm and a midline shift >5 mm, or a GCS < 9 with a traumatic ASDH <10 mm and a midline shift <5 mm without extracranial explanations for the comatose state, for whom clinical equipoise exists regarding the preferred treatment. Intervention: Patients are randomized to either early surgical hematoma evacuation (A) or conservative management on the ICU or the ward (B). In case of neurological deterioration during conservative management, delayed surgery can be performed. The exact neurosurgical technique will be left to the discretion of the surgeons. Main study parameters/endpoints: Functional outcome after 1 year, expressed by the rating on the Extended Glasgow Outcome Scale (GOS-E) Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Both treatment strategies are already used in current clinical practice as standard medical care. Therefore, there are no extra risks for patients participating in the study compared to patients outside the study. Study participation adds a minimal burden of three follow-up evaluations by visit in the first year (at 3, 6 and 12 months) and subsequent yearly evaluations by phone or postal until five years after the injury. Future elderly patients with a traumatic ASDH will benefit mostly from this study's results.

Endoscopic variceal ligation (EVL) is used to control and prevent variceal bleeding in patients with liver cirrhosis, but it can be complicated by bleeding from post-EVL ulcers. the current study aims at evaluating the potential benefit of different acid-suppressive therapies in prevention of post band ligation ulcer/bleeding. We will include 234 patients with cirrhotic portal hypertension undergoing endoscopic band ligation. Patients will be randomly allocated into one group of acid suppressive therapy (Vonoprazan or pantoprazole) versus placebo for 14 days. Re-endoscopy will be done after 2 weeks of treatment to assess the healing of post ligation ulcers. Any form of upper gastrointestinal bleeding will be documented.

The study is a prospective, randomized, double blinded, placebo controlled trial that aims to investigate the hypothesis that early administration of tranexamic acid (TXA) following diagnosis of hip fracture will lower pre and postoperative blood loss and transfusion rates. Patients who present to the hospital with a hip fracture will be recruited and randomized into two treatment arms. The treatment group will receive 1950mg of oral TXA (three tablets, 650 mg each) and the control group will be given three tablets of oral placebo while in the Emergency Department. Patients will then be admitted to the Orthopaedic Trauma service and treated surgically with cephalomedullary nail, hemiarthroplasty, sliding hip screw, percutaneous screws, or total hip arthroplasty.

A Randomized Controlled Non inferiority Trial will be conducted to see the feasibility, acceptability and efficacy of S-Condom Uterine Tamponade in women with atraumatic PPH and not responding to first line of treatment.

The aim of this clinical trial is to test if carbetocin is as effective as oxytocin plus misoprostol in decreasing intraoperative blood loss in women undergoing planned cesarean section. The main question it aims to answer is: * Is carbetocin as effective as oxytocin plus misoprostol in decreasing intraoperative blood loss in women undergoing planned cesarean section? Researchers will compare 2 groups: women receiving Oxytocin plus Misoprostol; women receiving Carbetocin as regards: estimated blood loss

The aim of the study is to assess the prophylactic role of tranexamic acid in reducing blood loss during and after elective cesarean section delivery in high risk patients. Comparing effect of administration of 1gm of TXA half an hour before elective C-section , effect of administration of 1gm of TXA on the start of uterine incision and placebo effect, Where in all an addition of prophylactic uterotonics is given, in a randomized control, double blind trial of 3 groups.

This double-blind, randomized controlled trial will evaluate the effect of the route of administration of 10 IU of oxytocin on the average blood loss postpartum. Participants will be randomized to receive 10 IU of oxytocin by IV infusion or 10 IU of oxytocin by injection IM

The objective of this study is to determine the effect of 1g of IV tranexamic acid given within 1 hour pre-operatively on intraoperative blood loss at time of hysterectomy.
