Filter by:Tranexamic (TXA)acid is an inexpensive, antifibrinolytic drug long used to control bleeding due to surgery, menorrhagia, or trauma. Additionally, tranexamic acid has been shown to reduce bleeding during cesarean delivery as well as the need for additional uterotonic agents, albeit to a minimal degree. However, previous studies have been performed only in women with a standard risk for postpartum hemorrhage( PPH) and have not focused on assessing the effects of tranexamic acid in high‐risk women. The aim of this study is to evaluate the efficacy of IV versus topical application of tranexamic acid in reducing blood loss during and after elective C.S. The Research Question Is topical application of Tranexamic acid effective in reducing blood loss during and after an elective Caesarean section? The Research Hypothesis the TXA could be able to reduce blood loss during and after elective Caesarean section. The null hypothesis will, therefore, state that: There will be no difference between topical and IV TXA and placebo in reducing blood loss during and after elective Caesarean section.
Angiogenesis is inherently associated to bone formation and healing. During implant osseointegration, a successive and successful angiogenic processes has to occur to promote bone formation. In 1969, Branemark et al. demonstrated that direct contact between bone and titanium implant surface was possible, defining osseointegration as "the direct, structural, and functional contact between live bone and the surface of a functionally loaded implant". Consequently, the need of an empirical measurement appeared. With the introduction of resonance frequency analysis (RFA), it is now possible to measure the degree of implant stability at any time during the course of implant treatment and loading. In this way, changes in implant stability can be monitored over the time and it is likely possible to find implants at risk of failure before they become loose. The rationale of this study is to analyse how important a good vascularization is for the future bone formation around dental implants.
This prospective, randomized, active-controlled, parallel arm study compares the safety and financial benefits of arterial thromboembolism prophylaxis with Warfarin vs. Rivaroxaban (A novel oral anticoagulant) in patients with new onset atrial fibrillation after sternotomy for cardiac operations.
Nurses at Royal Derby Hospital, UK have been trained to use a comprehensive protocol based dysphagia assessment (Dysphagia Trained Nurse Assessment (DTNAx)) to assess all acute stroke patients on admission. This study aims to validate the tool by comparing it to the gold standard assessment - Videofluoroscopy and usual assessment by a Speech and Language Therapist. Inter-rater and intra-rater reliability will also be tested by comparing the assessment results of two different nurses or the same nurse.
Haemorrhagic stroke, an emergency caused by bleeding in the brain, often leads to death or long-term disability. A quarter of these patients are taking blood-thinning drugs (antiplatelet drugs, such as aspirin) because they are at risk of a heart attack or ischaemic stroke. Patients taking these drugs are more likely to die or be disabled if they have a haemorrhagic stroke. At present, there is no effective treatment for reversing their effects. Desmopressin is a drug which may reverse the effects of antiplatelet drugs and stop bleeding. The investigators would like to run a large randomised trial to see if Desmopressin can reduce the number of people who die or are disabled after haemorrhagic stroke.
to compare effectiveness and tolerability of carbetocin versus syntometrine in prevention of Postpartum hemorrhage after cesarean section
This is a phase 1/2a, randomized, double blind, single-center study comparing standard care alone to standard care with Aggrastat in patients diagnosed with aneurysmal subarachnoid hemorrhage.
Patients having a hip or knee replacement can lose almost a third of their blood during and after the operation. Many patients, especially those who are older will need a blood transfusion, suffer from anaemia, or have a slow recovery after the operation. Tranexamic acid is a medication used to treat or prevent excessive blood loss, but in joint replacements, is only used in patients who are likely to bleed a lot. This trial aims to find out how well tranexamic acid works to reduce blood loss after the operation in a large group of patients having a hip or knee replacement, including those at risk of blood clots. This study also aims to find out how safe tranexamic acid treatment is to use in different patients and the best way to give tranexamic acid (in tablet form or through a drip), as well as how much to give and how long it should be given after an operation. All adults awaiting non-emergency hip or knee replacement surgery will be considered. Patients who are suitable and agree to take part are randomly placed in one of two treatment groups: receiving tranexamic acid during the hip or knee operation through a drip, or receiving treatment during the hip or knee operation through a drip plus taking a tablet every 8 hours up to 24 hours after the operation. Initially, a no treatment group was included, however, one year after the trial started, the Data Monitoring and Ethics Committee who check safety, advised to stop allocation of patients to the no treatment group. For all patients, blood loss is recorded up to 48 hours after surgery. Blood samples are also taken in order to measure how well the heart and blood clotting systems are working. If the routine kidney function tests taken before the operation show less than normal function, a lower dose of tranexamic acid is used. It is expected that patients who receive the tranexamic acid will lose much less blood during and after their operation, and so be less likely to need a blood transfusion, have reduced stress on the heart and have an easier recovery. It is thought that patients with a history of clots are more likely to have another clot when taking tranexamic acid. Therefore, this trial will include these patients to try and find out if this is true as these patients will benefit the most from reduced blood loss.
• Patients will be divided into two groups 100 patients will receive routine ecbolics (for example oxytocin) after delivery of baby The 100 patients will receive routine ecbolics (for example oxytocin) after delivery of baby plus 400 microgram misoprostol rectally with catheterization and another 400 microgram rectally after closure of abdomen Then we will compare between two groups regarding - Intaoperative blood loss - Risk of Postpartum hemorraghe in the first 24 hrs - HB pre and postoperative for all patients Intraoperative blood loss will be estimated by the number and weight of soaked towels and amount of blood in suction unit
The purpose of the study is to assess the frequency and intensity of intramyocardial haemorrhage in patients with primary STEMI and different reperfusion strategies.
