Active clinical trials for "Blood Loss, Surgical"

Patients undergoing cardiac surgery could develop excessive perioperative bleeding requiring transfusions of blood products. Desmopressin (DDAVP), already used for patients with von Willebrand syndrome, could reduce bleeding and transfusion requirements in these patients when administered ev (0.3 mg/kg) in 20-30 minutes postoperatively.

Exploratory tympanotomy is surgical access to the middle ear, made for diagnosis and management of unexplained conductive hearing loss, performed under an oto-microscope across the external auditory canal after tympanic membrane elevation to explore the middle ear structures

This will be a single-centre, randomised, endoscopist-blind, parallel-group study in patients who are scheduled endoscopic submucosal dissection (ESD) for gastric mucosal lesion. The primary objective is to observe whether a regimen of 7-day oral esomeprazole premedication can alleviate intraoperative bleeding in patients scheduled for ESD due to gastric mucosal lesions.

Prospective, randomized, double-blind, placebo-controlled, mono center, Phase III trial to compare EXACYL in preventive with placebo on perioperatory bleeding in orthognathism surgery.

This is a multicenter, cluster randomized controlled trial to assess the effects of an optimized intraoperative fluid and blood management strategy on postoperative complications.

This study investigates the effect of tranexamic acid, a medication that helps reduce bleeding, in patients undergoing surgeries around their eyes.

The objective of this study is to evaluate the effect of Tranexamic Acid (TXA) on blood loss and need for perioperative blood transfusion following intertrochanteric and subtrochanteric femur fractures. TXA is a antifibrinolytic medication that prevents the breakdown of blood clots by inhibiting the activation of plasminogen to plasmin in the coagulation cascade. Our hypothesis is that by providing TXA at the time of hospital admission it will decrease the amount of preoperative and intraoperative bleeding thereby leading to a decreased need for post-operative transfusion. This a double blinded, placebo controlled, therapeutic trial in which half of patients will be randomized to receive TXA at the time of hospital admission and half of patients will receive a placebo.

Recent guidelines of the ACC/AHA suggest that elective non-cardiac surgery (NCS) should optimally be delayed one year after percutaneous coronary intervention (PCI) with drug-eluting stent (DES). Regarding the antiplatelet agents, dual antiplatelet therapy, or at least aspirin is recommended to be continued considering the relative risk of bleeding and stent thrombosis especially during the first 4 to 6 weeks after DES implantation. However, these recommendations are based upon insufficient and conflicting evidences.

Blood products and intravenous fluids are frequently used in the treatment of children who have undergone cardiac surgery in order to maintain hemodynamic stability. Optimal hematocrit values during CPB are still being discussed in children undergoing congenital cardiac surgery. The overall complication rate for transfusion in adults is 2.5 complications per 1000 units, while 10.7 complications per 1000 transfusion in children. The aim of this study is to investigate the effects of the our transfusion strategies used in pediatric cardiac surgery on duration of intensive care unit, duration of postoperative mechanical ventilation and mortality.

Study Design: Randomized Controlled Clinical Trial. Study Population: The study population will be a consecutive series of participants attending the Early Cancer Detection Unit (ECDU) at Ain Shams University Maternity Hospital. 80 women who are scheduled to undergo a hysteroscopic myomectomy will be included and will be randomized into two groups: Group A: women will undergo a hysteroscopic myomectomy with the use of (TXA) Kapron in the distention medium Group B: women will undergo hysteroscopic myomectomy with the use of placebo(normal saline in the distention medium). Randomization will be performed using a Computer-generated randomization system. The allocated groups will be concealed in serially-numbered sealed opaque envelopes that will only be opened after recruitment. Patient allocation will be performed prior to the induction of anesthesia by an independent person, who will not otherwise be involved in this study. The trial will be appropriately blinded; the participants, outcome assessors and the surgeon performing the procedure will be blinded to the medication type, which will be used inside the distention medium. Therefore, this study will be a randomized double blind prospective clinical Methodology: Informed written consent obtained from the participant. History Personal history Menstrual history Detailed obstetric history Surgical intervention especially uterine surgeries and any post-operative complication History of drug intake, especially hormonal treatment or anticoagulant therapy. Routine preoperative investigations in addition to a serum pregnancy test if pregnancy is suspected. Physical examination including general, abdominal and pelvic examination. Hysteroscopy will be performed in the early proliferative phase using normal saline as a distention medium. Only in intervention group (TXA group) KAPRON (Tranexamic acid) will be added to the injected media. In intervention group 500 mg of Kapron for every 500 ml of distending media will be added. In the control group, placebo .i.e. ,normal saline in the same form will be injected inside every 500 ml of the distention medium. The trial will be appropriately blinded; the participants, outcome assessors and the surgeon performing the procedure will be blinded to the medication type, which will be used inside the distention medium. Therefore, our study will be a randomized double blind prospective clinical trial. Intraoperative bleeding and quality of view will be observed. A blood sample will be taken from each participant in both groups after 24 hours from the end of the operation for both hemoglobin and hematocrit levels. Types of outcome measures: Primary outcome measures: Estimated Blood loss defined as comparing the hematocrit and hemoglobin at base line (preoperative ) and 24 hours after surgery with the Tranexamic acid compared to the control group. Secondary outcome measures: The quality of view, duration of surgery, the volume of injected media, intraoperative complications and the success of the completion of the operation will be secondary outcomes.
