Filter by:Although tonsillectomy is one of the most commonly performed surgeries, a review of literature reveals no articles dealing with the study of intraoperative blood loss in tonsillectomy and adenotonsillectomy according to the use of nondepolarizing muscle relaxants. The primary aim of our trial will be to compare blood loss in the operating theatre and postoperatively in two groups of children having adenotonsillectomy. The trial numbers will be randomised in blocks.
Evaluation of DOACs treatment on post-extraction bleeding
This pilot study will assess the performance of the Quantra System with the QStat Cartridge versus standard of care coagulation testing in bleeding pregnant women at delivery.
The research team proposes a prospective, observational study to better understand how TEG can be useful in guiding clinical practice in the Main OR for subject's undergoing high transfusion risk surgeries. Intraoperatively, transfusion of blood products is frequently required to restore oxygen carrying capacity, perfusion and improve coagulation. Both under and over transfusion pose significant risks, particularly to pediatric patients with small starting intravascular volumes. Thromboelastography (TEG) is a validated method of dynamically assessing intraoperative coagulopathy via functional assay. However, while FDA approved and widely used in the adult setting, TEG is not commonly utilized in the setting of bleeding pediatric patients. Recently, TEG has been made available at BCH for clinical purposes and is being used solely in the cardiac surgery setting. The investigators aim to provide TEG data for non-cardiac pediatric surgical cases with a high risk of intraoperative blood loss in order to assess the impact of this tool on intraoperative management.
This is a multicenter, cluster randomized controlled trial to assess the effects of an optimized intraoperative fluid and blood management strategy on postoperative complications.
obstetric hemorrhage remains one of the major causes of maternal death in both developed and developing countries. Because of its importance as a leading cause of maternal mortality and morbidity, and because of evidence of substandard care in the majority of fatal cases, obstetric hemorrhage must be considered as a priority topic for national guideline development. Some obstetricians believe that the cervix of women at non-labor cesarean section is undilated and might cause obstruction of blood or lochia drainage, leading to postpartum hemorrhage and endometritis from the collection of lochia or debris. Dilatation of the cervix helps with the drainage of blood during postpartum, reducing intrauterine infection or the risk of postpartum hemorrhage. To avoid this problem, some obstetricians routinely dilate the cervix from above during an elective/ non-labor cesarean section using finger, sponge forceps or other instruments
Decompressive craniectomy is frequently used to treat increased intracranial pressure or an intracranial mass effect. Trephined Syndrome describes a neurological deterioration, which is attributed to a large craniectomy. The symptomatology is varied but includes headache, aggravation of a hemisyndrome or cognitive disorders, often has an orthostatic component and improves or disappears with cranioplasty. The incidence of Trephined Syndrome has been reported between 7% and 26%. However, it might be underestimated if the course of cognitive functions before and after cranioplasty were insufficiently documented.
Prophylactic use of tranexamic acid to reduce intra and postoperative bleeding in primary sleeve gastrectomy procedures will be studied.
Intravenous Tranexamic Acid Versus Pericervical Tourniquet To Decrease Blood Loss In Trans-Abdominal Myomectomy
Tonsillectomy (removal of the tonsils) is a very common surgery in children. Bleeding after tonsillectomy is one of the risks of this surgery and can be more dangerous in children since they have less blood volume than adults. In order to improve recovery after tonsillectomy, steroids (medication that is a strong anti-inflammatory) are often given during the surgery. Recently, a study showed steroids given at the time of tonsillectomy increase the risk of bleeding significantly over children who did not receive steroids. This finding has raised concerns in the Ear, Nose, and Throat (ENT) community since most ENT's use steroids during tonsillectomy in children. The investigators look to explore this question further. To answer the question of whether perioperative steroid administration significantly affects the rate of post-tonsillectomy bleeding, the investigators propose to test the following hypotheses in a prospective, randomized, blinded placebo-controlled trial: dexamethasone does not cause an increase in post-operative bleeding rate in tonsillectomy.
