Filter by:This study aims to use validated tools as well as new technology to examine changes in bleeding patterns among women who are initiating the copper T380A IUD.
The purpose of the study is to investigate whether platelet indices from automated haematology equipment, whole blood impedance aggregometry and a standardized bleeding questionnaire predict bleeding in admitted patients with thrombocytopenia of various causes.
All patients (≥18 years) with a spontaneous SAH proven by computed tomography (CT), magnetic resonance imaging (MRI) or lumbar puncture will be considered for this trial. Upon presentation to a neurosurgical centre the patients will be treated according to the local protocol. Upon admission the patient is clinically evaluated for occurrence of clinical signs of brain herniation syndromes (anisocoria, bilateral dilated pupils, posturing). Usually first line treatment includes neurological resuscitation (placement external cerebrospinal fluid drainage in case of hydrocephalus, treatment of seizure, and general intensive care measures). Hereafter, the patient is clinically evaluated for a second time. The patients will be graded according to the usual WFNS scale and the modified "herniation WFNS" scale. The whole treatment of the patient will be according to local clinical protocols. Outcome will be measured at six and twelve months by trained investigators who are unaware of clinical data. The primary endpoint is the difference of specificities of the WFNS and hWFNS with respect to poor outcome (mRS 4-6) at 6 months after initial haemorrhage. Given that specificity and sensitivity are negatively correlated, difference in sensitivity will be the second primary outcome. The null hypothesis to be tested is that the ratio of the true negative rates (specificity) of the hWFNS and WFNS scores is 1.35 i.e. the new score will detect 35% more patients as truly negative (good outcome) as compared to the old score. In addition and because of the negative correlation between specificity and sensitivity we will also test that the ratio of the true positive rate (sensitivity) is not below 0.82 i.e. the new score will not more than 18% less patients as truly positive (poor outcome).
The purpose of this study is to assess whether the administration of a low dose of tranexamic acid just after vaginal delivery can reduce the incidence of immediate postpartum hemorrhage, in women who receive a prophylactic administration of oxytocin.
Hip fractures are associated with a large hidden blood loss. That is, the total blood loss associated with hip fracture surgery is much greater than that observed intra operatively. There is currently no viable method of identifying patients at risk of transfusion. The on admission haemoglobin level has been shown to be falsely reassuring . We are conducting a study of 200 consecutive hip fracture patients. Thrombelastography (TEG) is taken on admission. The results are blinded to clinicians. Results will be evaluated at the end of the study, comparing intra-operative and total blood losses with the TEG profile of the patient.
This study will evaluate acupuncture's effect of preventing vasospasm after SAH. A total of 80 participants will be recruited and will be randomized to a study group or a control group. Acupuncture, electroacupuncture and intradermal acupuncture will be done at every session in a study group, while mock transcutaneous electrical nerve stimulation(mock TENS) and sham intradermal acupuncture will be carried out in a control group.
Phase 1 clinical trial for the safety and dose determination of Pneumostem (human umbilical cord blood derived mesenchymal stem cells) in the premature infants with intraventricular hemorrhage (IVH, grade 3-4)
The purpose of the study is to assess the efficacy and safety of Octafibrin for on-demand treatment of acute bleeding in subjects with congenital fibrinogen deficiency.
PostPartum hemorrhage (PPH) is a major cause of maternal death worldwide. Oxytocin is the most commonly used uterotonic drug to prevent and treat PPH in North America. However oxytocin has a very short duration of action, requiring a continuous infusion to achieve sustained uterotonic activity. Moreover large doses are associated with adverse effects like hypotension, nausea, vomiting, dysrhythmias and ST changes. The Society of Obstetricians and Gynecologists of Canada (SOGC) has recommended a single dose of 100 mcg of carbetocin at elective cesarean delivery to promote uterine contraction. In three studies recently performed at Mount Sinai Hospital, the investigators have found no difference in uterine contractility between the doses of 20- 120 mcg carbetocin and that the ED90 is 14.8 mcg. Thus a larger trial comparing the minimum effective dose determined in the previous three trials with the standard 100 mcg dose is necessary to confirm these findings.
E-Aminocaproic acid (EACA) is an anti-fibrinolytic agent that is used to decrease blood loss and transfusion requirements after several orthopedic procedures. The aim of this prospective double-blind placebo-controlled randomized trial is to determine whether IV EACA reduces intra-operative calculated total blood loss in patients undergoing bilateral varus rotational osteotomy (VRO). This study will also investigate intraoperative cell saver utilization, transfusion of allogeneic blood, hospital length-of-stay (LOS), short term complications, and long-term outcomes.This study will provide Level I evidence and has the potential to improve outcomes in children undergoing this procedure.
