Filter by:In this randomized, double-blind control trial to evaluate the effect of ketorolac given at the time of cord clamp has on estimated blood loss and postcesarean pain control. Patients will be randomized to either placebo or ketorolac prior to surgery. Those randomized to ketorolac will receive ketorolac at cord clamp and three additional doses every 6 hours (total 4 doses/24 hours). Those in the placebo group will receive normal saline during those time periods. Our primary outcome is to assess whether intra-operative ketorolac increases the estimated blood loss during Cesarean delivery.
The purpose of this European study is to demonstrate the safety and performance of the SurgiClot® dressing in the treatment of cancellous bone bleeding.
This is a prospective and observational study to evaluate oncologic patients that presented upper gastrointestinal bleeding with the use of some prognostic scores.
A randomized, double-blind, single-center and controlled study comparing the efficacy and safety of intravenous administration of tranexamic acid to reduce blood loss in simultaneous bilateral total knee arthroplasty.
Hypothesis: Cortical spreading depolarizations are inhibited by the NMDA receptor antagonist Ketamine Aim 1: To demonstrate, in a group of patients with acute severe brain injury requiring surgery including traumatic brain injury and aneurysmal subarachnoid hemorrhage, whether use of continuous infusion of ketamine decreases frequency of occurrence of cortical spreading depolarizations.
This study will investigate the effects of Leukocyte reduced cold-stored platelet transfusions used in treatment of immediate postoperative blood loss in patients undergoing thoracic surgery in combination with extracorporal circulation. Today platelet concentrates are stored at 22 degrees C . This is a prospective, randomized, unblinded, non-inferiority two-arm study. Aim of study is to compare platelet function in bleeding patients transfused with leukoreduced platelet concentrates stored cold (4 degrees C) and in room temperature (22 degrees C). Storage time for RCT platelet concentrates are up to 7 days. Patients with expected time on extracorporal circulation more than 120 minutes and/or medical platelet inhibitors will be included. Platelet function will be assessed by use of Multiplate Aggregometry, Thromboelastography (TEG) and/or Thromboelastometry (ROTEM). In addition post operative bleeding, and adverse events will be recorded. After completion of recruitment of patients to RCT study of platelet stored cold for up to 7 days, a follow up prospective observational study of platelets stored cold for up to 14 days is performed. Additonal information 2019, May 03: This trial was registered on Clinical Trials.gov with an original plan to use non-inferiority testing of between-group differences in platelet function. Due to lack of evidence needed to set acceptable tolerance margins for the non-inferiority testing, independent reviewers with expertise in clinical trial design recommended they be replaced by standard tests of superiority, commensurate with the early phase of the trial. Further, post-operative chest tube drainage was chosen as the primary outcome to better present the pilot study's focus on the control of clinically significant bleeding.
100 patients with postmenopausal bleeding were assessed with 2D vaginal ultrasound and 3D power Doppler ultrasound using the international endometrial tumor analysis group and office hysteroscopy with taking samples for histopathological analysis.
A retrospective real world analysis of bleeding events with ticagrelor compared to clopidogrel in ACS patients.
The purpose of this study is to determine the feasibility of conducting a large trial examining the effect on clinical outcome of a liberal red blood cell (RBC) transfusion strategy compared to a restrictive strategy (usual care) in patients with aneurysmal subarachnoid hemorrhage (SAH).
Subarachnoid haemorrhage (SAH) secondary to ruptured aneurysm represents 5 to 15% of all cases of stroke. The mortality rate of SAH is 40% and the risk of serious neurological sequelae among survivors is 10 to 20%.The causes of morbidity and mortality are mainly related to the initial damage induced by SAH and delayed cerebral ischaemia (DCI), which is generally secondary to cerebral vasospasm. Cerebral vasospasm is one of the main factors of poor prognosis after SAH, as it is associated with a 1.5- to 3-fold increase in the mortality rate during the 2 weeks following SAH in these patients. Despite a significant improvement in the time to management of this disease and the fact that the ruptured aneurysm is very often rapidly excluded by surgical or endovascular intervention, patients who survive the initial SAH remain at risk of severe complications over the following 2 weeks. Vascular stenosis of an arterial segment, called cerebral vasospasm, is observed in more than 70 to 95% of cases on digital subtraction angiography between the 7th and 14th days after ruptured aneurysm. This angiographic vasospasm can be responsible for cerebral infarction in 52 to 81% of cases. Despite 50 years of research, no clearly demonstrated effective treatment for vasospasm is currently available. This is a multicentre, randomized, comparative study, including 364 patients during the acute phase following ruptured aneurysm, in whom management is very often limited to control of complications, after exclusion of the aneurysm. The objective of this study is to validate the efficacy of transcutaneous trigeminal nerve stimulation for the prevention of vasospasm and limitation of the consequences of delayed cerebral ischaemia after SAH. This is an innovative project, as it comprises intervention in these patients prior to the development of complications and could limit the development of these complications. The prevention tool, based on external facial nerve stimulation, is a totally innovative, reversible and noninvasive technique. Use of nerve stimulation in this indication has never been previously reported and could radically modify the intensive care management of this disease over the years to come.
