Filter by:The investigators hypothesize that prophylactic clipping after colonoscopic polypectomy can reduce risk of delayed PPB among DOAC users. The investigators also hypothesize that pre-endoscopy drug level can predict the risk of hemorrhagic complications after the procedure.
Portal hypertension (PH) is a common complication of chronic liver disease and a major cause of morbidity and mortality in cirrhotic patients. One of the most serious complications of liver cirrhosis is esophageal varices (EV) bleeding. The hepatic venous pressure gradient (HVPG) is the gold standard for detecting portal hypertension and its complications. Furthermore, HVPG is the most reliable method for assessing the efficacy of treatment with nonselective -blockers (NSBB), which is the preferred therapy in patients with EV who are at high risk of bleeding (HRV) and as a secondary prophylaxis in the prevention of rebleed. However, the HVPG is an invasive method that is not widely used and necessitates specialized skills. For these reasons, clinical research over the last decade has been focused on identifying non-invasive tests (NITs) capable of evaluating the PH degree and its changes. The most investigated non-invasive tests are liver and splenic stiffness measurement. In advanced cirrhosis, the increase in portal pressure is less dependent on intrahepatic resistance to portal flow due to fibrosis progression and more dependent on extra-hepatic factors such as hyperdynamic circulation and splanchnic vasodilation hence correlation between LSM and PH decreases for HVPG values higher than 12 mmHg.
Resection of malign musculoskeletal tumors and reconstruction with large tumor prostheses often results in relevant blood loss requiring hemodynamic stabilization and transfusion. The use of novel electrosurgical electrodes is assessed retrospectively regarding the potential to reduce blood loss and the need for transfusions.
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.
This is a prospective, single-center, randomized control study to determine if video education at the time of postpartum discharge improves patient knowledge on the warning signs for the top three causes of severe maternal morbidity (infection, hemorrhage, and blood pressure disorders) in the first seven days following delivery. Participants will be randomized to written discharge education + video education (intervention) vs standard discharge education (control). They will complete a baseline questionnaire and a post-discharge education questionnaire during their postpartum stay to assess for knowledge improvement. The investigators hypothesize that video education will improve patient's knowledge of severe maternal morbidity warning signs.
The overall goal is to establish the safety and efficacy of colchicine in ICH patients for the prevention of major cardiovascular events and brain injury. Colchicine for the prevention of vascular events after an acute intracerebral hemorrhage (CoVasc-ICH) is a vanguard pilot trial designed to obtain the factual feasibility prerequisites essential for the planning, design, funding and execution of a subsequent phase III trial.
Our study aims to evaluate the efficacy of intramyometrial injection of Terlipressin versus intramyometrial injection of Carbetocin on hemoglobin level in women undergoing abdominal 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.
To evaluate the effectiveness of topical TXA in reducing blood loss compared to H2O2 wash. The primary outcomes : 1. Estimation of Intraoperative blood loss and blood transfusion. 2. Recording Postoperative blood drainage. 3. Comparing Hemoglobin levels (pre and postoperative). The secondary outcomes : 1. Surgical site infection (SSI) 2. Length of hospital stay.
Cerebral vasospasm is characterized by a vasoconstriction of cerebral arteries causing a reduction of cerebral blood flow (CBF) and leading to ischemia and infarction of the brain parenchyma. Cerebral vasospasm is a serious complication of aneurysmal subarachnoid hemorrhage (SAH) with high morbidity and overall mortality of 40-50%. Although the exact mechanisms of spinal cord stimulation (SCS) on the innervation of cerebral vessels are still unclear, several hypotheses have been formulated and studies in animals and human performed with very promising results. This is a proof of concept study to better understand the effect and mechanisms of cervical spinal cord stimulation on cerebral vasospasm after aneurysmal SAH in human.
The project focuses on perioperative bleeding that requires transfusion of blood products and supplementation of intravascular volume with crystalloids and colloids. The implemented fluid therapy affects coagulation and fibrinolysis, depending on the type of fluid used in an intravenous infusion. Massive haemorrhage significantly impacts the perioperative period and postoperative quality of life and requires individualized therapy, rending the ongoing project relevant from the perspective of the patients.
