Filter by:Hip fracture in elderly patients is a pathology with a high economic and health impact on the patient himself and on the National Health System, especially considering the significant aging of the population of the Basque Country. Despite advances, hip fracture remains in the clinical groups with the highest in-hospital mortality. Hip fracture is associated with numerous adverse events and high mortality. Numerous antifibrinolytics, such as tranexamic acid (TXA), have been used to limit bleeding in orthopedic surgery and thus prevent the need for blood transfusion. Numerous studies have shown that the use of tranexamic acid does not increase the risk of thrombosis. It is proposed to carry out clinical research with drugs without commercial interest. A randomized, double-blind clinical trial to assess the efficacy of tranexamic acid in reducing blood loss in elderly patients with hip fracture.
Oxytocin is the first-line drug to promote contraction of the uterus and prevent atony immediately after delivery. Nonetheless, unpredictable uterine atony refractory to oxytocin affects roughly 250,000 parturients annually in the U.S. and rates are increasing. This two-part study will measure the action of oxytocin at cesarean delivery. The first part will measure the pharmacokinetics of a single intravenous (IV) dose of deuterium-labeled oxytocin. The second part will measure the pharmacodynamics of all plasma oxytocin to see how concentrations correspond to the contractile effect on the uterus. After delivery of the fetus, study subjects will receive a bolus of IV deuterated oxytocin followed by an unlabeled oxytocin infusion. Venous blood samples drawn at multiple time points (within 1 hour after delivery) will be analyzed for plasma concentrations of labeled and unlabeled (endogenous + exogenous infused) oxytocin over time. Plasma concentrations will be compared with 0-10 uterine tone scores measuring uterine contraction strength, to describe the concentration-effect relationship. The goal of this study is to define both the pharmacokinetics and pharmacodynamics of oxytocin in parturients to help identify the cause(s) of failed first-line oxytocin therapy.
Comparison between Carbetocin and Oxytocin as prophylaxis against Primary Postpartum Hemorrhage.
Transoral robotic surgery (TORS )has been shown to offer excellent oncological and functional outcomes for treating cancer at multiple subsites of the head and neck. Post operative haemorrhage (3.1% to 13.1%) is the most common complication of this procedure and can lead to airway compromise. Ligation of individual feeding vessels in the neck can limit risk of severe bleed and is usually done when concomitant neck dissection is carried out with TORS. In salvage TORS, in the absence of any nodal disease of the neck, the neck is explored, nevertheless, for the sole purpose of tying the vessel. Endovascular embolisation is a minimally invasive, safe and effective procedure; known for treating refractory epistaxis and for reducing intra-operative bleeding for benign vascular head and neck tumour. The investigators propose that superselective endovascular embolisation to occlude feeding blood vessels prior to TORS in patients who do not require neck dissection is a feasible, safe and acceptable intervention; and therefore a plausible alternative conventional open neck vessel ligation.
Aim:This research was designed as a randomized controlled study to examine the effect of the game-based virtual reality learning method on the patient's post-operative admission to the clinic on the learning outcomes of the students. Desing: This study was designed as a randomized controlled study to examine the effect of the game-based virtual reality learning method on the patient's post-operative admission to the clinic on the learning outcomes of the students. Metod: The universe of the research will be nursing students who have taken the Surgical Diseases Nursing Course at Gazi University Faculty of Health Sciences Nursing Department in the 2021-2022 academic year. As a result of the power analysis using the G-power 3.1.9.7 package program; The effect size was calculated as 0.40 (It was seen from the literature studies that the effect size of the change in the knowledge score of the two groups was large effect size), and the total number of 68 samples is sufficient with 90% power, 5% margin of error, 95% confidence level, 20% drop-out Considering the rate of study, it was found sufficient to work with at least 82 people (Experiment: 41, Control: 41). For research data, "descriptive features form", "knowledge test form", "skill evaluation checklist", "student opinions form about game-based virtual reality game application", egameflow scale will be used.
The incidence of bleeding after metabolic surgery seems to increase. The administration of a drug (tranexamic acid) that can reduce bleeding could possibly also reduce bleeding after metabolic surgery. Objective: This study aims to determine whether administration of tranexamic acid before surgery can reduce postoperative bleeding in patients undergoing gastric bypass.
Gastrointestinal bleeding is defined as clinical evidence of bleeding manifested by melena, hematochezia that required endoscopic hemostasis. GI bleeding associated to endoscopic procedure is defined as clinical evidence of bleeding and a drop in hemoglobin of ≥ 2g/dL on the day of the procedure (early bleeding) or up to 14 days after the procedure (delayed bleeding).GI bleeding is, nevertheless, a common complication of endoscopic procedures, such as endoscopic mucosal resection (EMR) and endoscopic sub mucosal dissection (ESD). For example, colorectal ESD, which is technically more difficult than gastric or esophageal ESD because of the anatomical features of the colon, present an increased risk of delayed bleeding. According to literature, early bleeding occurs on average in 5,3% of endoscopic resections of the whole digestive tract, with bleeding rates per location as follows: esophagus 9.4%, stomach 9.1%, duodenum 3.6%, colon 3.4%. Concerning delayed bleeding, it is assessed to complicate 3.1% of endoscopic resection procedures. The bleeding rate in the duodenum is usually the highest (6.3%), followed by colon at (3.6%), stomach (1.5%) and esophagus (0.9%). Age, lesion size and piecemeal resection are associated with an increased risk of bleeding. Usage of aspirin or NSAIDs seems to not increase risk of post-polypectomy bleeding, while clopidogrel and warfarin do and should be discontinued in the periprocedural period to prevent the occurrence of post-polypectomy bleeding. Direct oral anticoagulants (DOAC) administration shows similar post-procedural gastrointestinal bleeding risk to anti-vitamin K antagonists (VKA) administration in patients undergoing endoscopic procedures.
Double lumen endotracheal tubes (DLT) are wildly used to maintain independent lung ventilation during thoracic surgery. Our aim is to assess whether the DLT bronchial cuff inflated or not is associated with tube displacement and bronchial mucosal injury while changing position.
To assess the ability of clinical and sonographic variables to predict the need of blood transfusion > 4 units of packed RBCS in women undergoing cesarian section for placenta previa .
Continuous renal replacement therapy is widely used in intensive care medicine, which is known as an alternative therapy to save injured kidney . Anticoagulation is an important part of this therapy. An insufficient anticoagulation would cause a poor curative effect of CRRT. Hemorrhage，heparin-induced thrombocytopenia (HIT), citrate accumulation, acidosis ad filter extra-cost usually happened on anticoagulation during CRRT. Therefore a new effective anticoagulation of CRRT needs to be carried out. Nafamostat Mesylate (NM) is a new anticoagulant. This serine protease inhibitor with broad spectrum can inhibit kinds of enzymes on the process of coagulation. NM is mainly rapidly decomposed in the liver and also removed by dialysis or filtration. The elimination half life of is only 8 minutes. If NM is applied as a regional anticoagulant, approximate 40% NM is removed by dialysis and / or convection in cardiopulmonary bypass circuit, and then rapidly degraded by esterase in liver and blood, which ensures security in patients with bleeding tendency. Based on the information above, the investigators designed an observational clinical study aimed to testify that NM would have equivalent anticoagulant results compared with those traditional ways and might even have a better effect than traditional anticoagulant therapy.The study team has investigated the current situation of CRRT in Shaanxi province in China through a cross-sectional survey last year. The survey involved 74 hospitals in Shaanxi province and the results basically illustrated a real status of CRRT. These scientific results helped investigators to design this multi-center, parallel, controlled, non intervention study and real world study.
