Filter by:In two randomized clinical trials the investigators have demonstrated that continuous postoperative pericardial flushing (CPPF) therapy can reduce postoperative blood loss and bleeding-related complications after cardiac surgery and that CPPF therapy is safe and feasible in an experimental setting. The Haermonics investigational device is a novel medical device that enables CPPF therapy to be used in daily clinical setting. The aim of this study is three-fold. First, to evaluate the safety and functionality of the Haermonics investigational device. Secondly, to investigate the effect of CPPF therapy on bleeding related complications in the adulty cardiac surgery population. Thirdly, to explore the effect of CPPF therapy on intraluminal chest tube clogging.
Prospective, Multicenter, Double-blind, Randomized, Study to Evaluate DrugSorb-ATR Removal of Apixaban and Rivaroxaban to Reduce Likelihood of Serious Bleeding in Patients Undergoing Urgent Cardiothoracic Surgery
Tonsillectomy is one of the most frequently performed surgical interventions in children. However, it is associated with a high incidence of PostOperative Nausea and Vomiting (PONV), severe pain and haemorrhage. There is strong evidence on the efficacy of Dexamethasone in reducing the incidence of PONV and pain after tonsillectomy, which led to consider this drug as a first line treatment in routine anaesthesia practice in such surgical setting. However, in the last decade, there have been arguments about the potential role of Dexamethasone in increasing the risk of postoperative bleeding in children and studies addressing the haemorrhage risk following administration of Dexamethasone for tonsillectomy are inconclusive.Thus, this study is aimed at providing evidence for the safety profile of Dexamethasone with regard to the risk of post-tonsillectomy bleeding in children when administered as a single intraoperative dose.
The aim is to conduct a double-dummy multi-centre randomized controlled clinical trial of application of topical dose of tranexamic acid (TxA) versus the usual intravenous TxA in patients undergoing on-pump cardiac surgery.
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.
This is a randomized prospective study to determine the optimal postoperative pain medication regimen for adults (18 years old and older) undergoing tonsillectomy with or without adenoidectomy for chronic tonsillitis and/or snoring and/or obstructive sleep apnea. All participants will undergo the same tonsillectomy surgical technique (with or without adenoidectomy) under general anesthesia and be randomized to one of three postoperative pain control regimens (all of which are commonly used pain medications for post-tonsillectomy pain): 1. Norco (Hydrocodone and Acetaminophen) 2. Percocet (Oxycodone and Acetaminophen) 3. Dilaudid and Tylenol (Acetaminophen) Participants will be discharged home the day of surgery and will be sent home with questionnaires to assess their daily pain level, oral intake, amount of nausea/vomiting, and amount of pain medications taken for the 14 days following their surgery. Data will be collected and analyzed to determine if there is a difference in pain levels or oral intake or nausea/vomiting in the different pain regimen groups. Secondary endpoints will include weight change from preoperative weight to weight at 2-3 weeks after surgery in addition to postoperative complications including visits to the Emergency Department and post-tonsillectomy bleed rates. Participants will be seen 1-2 weeks following their surgery in the ENT (Ear, Nose and Throat) clinic per normal postoperative protocol and will not require any specific clinic visits related to this study.
The purpose of this study is to evaluate the effect of combining two interventions already in use at some institutions for reducing post-operative pain following tonsillectomy or adenotonsillectomy. The standard of care at most institutions is to leave the tonsillectomy wound bed exposed to heal on its own over one to two weeks. At many institutions, surgeons inject or topically apply local anesthetics such as bupivacaine hydrochloride to the tonsillectomy wound bed to help reduce post-operative pain. At other institutions, surgeons apply a layer of fibrin sealant, which is derived from the proteins that help form blood clots in blood, to the tonsillectomy wound bed in order to cover the site and reduce irritation and exposure of the wound bed. Use of fibrin sealant has the additional benefit of potentially reducing postoperative bleeding (hemorrhage) rates. Both the post-tonsillectomy use of bupivacaine (injection and topical) and the use of topical fibrin sealant application have been studied previously in the scientific literature; some studies show a clear benefit, others show no significant reduction in pain when they are used. No studies have documented harm. The purpose of this study is to evaluate the efficacy of infusing bupivacaine anesthetic into the fibrin sealant prior to application to the tonsillectomy wound bed. In this way, the combined product would function as a sort of "medicated bandaid" covering the painful wound bed and slowly delivering an entirely safe total dose of bupivacaine into the wound bed to reduce post-operative pain. Parents will be provided post-operative pain measurements to complete during the first 10 postoperative days and return to the researchers for data analysis.
Massive bone tumour resection is often associated with important postoperative bleeding. This may determine systemic (anaemia), as well as local complications (wound healing, seroma, haematoma). The objective of this study is to determine whether the use of topical tranexamic acid or topical Evicel® will reduce the perioperative bleeding comparing it with usual haemostasis.
Total hip arthroplasty (THA) is a procedure associated with perioperative blood loss, requiring blood transfusions in some patients. The major cause of this blood loss is due to surgical trauma that induces the clotting cascade and fibrinolysis. Several previous studies and meta-analyses have shown that tranexamic acid is an effective antifibrinolytic agent that reduces blood loss in a variety of situations. Tranexamic acid given in an intravenous form has been extensively studied and shown to be efficacious in cardiothoracic, spine surgical procedures as well as total knee arthroplasty (TKA) and THA. Similarly, topical tranexamic acid has been associated with decreased blood loss in cardiac surgeries as well. Recently, results from a prospective randomized study on the topical use of tranexamic acid in total knee arthroplasty found it to be effective for reducing postoperative blood loss. Taking all of the above into consideration we have proposed a study to evaluate effects of topical application of tranexamic acid on postoperative blood loss and blood transfusion on patients undergoing total hip arthroplasty. The aim of this study is to evaluate the efficacy of the topical application of tranexamic acid on blood loss in patients undergoing a primary unilateral total hip arthroplasty.
