Active clinical trials for "Blood Loss, Surgical"

during PCNL; A few milliliters of nor-epinephrine is injected into the intended tract after puncture of pelvicalyceal system and before its dilatation compared to injection of saline (placebo). hemoglobin change & blood loss is estimated and will compared.

The aim of this clinical trial is to test if carbetocin is as effective as oxytocin plus misoprostol in decreasing intraoperative blood loss in women undergoing planned cesarean section. The main question it aims to answer is: * Is carbetocin as effective as oxytocin plus misoprostol in decreasing intraoperative blood loss in women undergoing planned cesarean section? Researchers will compare 2 groups: women receiving Oxytocin plus Misoprostol; women receiving Carbetocin as regards: estimated blood loss

The objective of this study is to determine the effect of 1g of IV tranexamic acid given within 1 hour pre-operatively on intraoperative blood loss at time of hysterectomy.

Peri operative haemorrhage following cardio Pulmonary Bypass may occur in 5 to 10% of cardiac surgical interventions. Treatment of such complication often necessitates various combinations therapeutic intervention including allogenic blood products administration, drug use and/or surgical intervention. All are expensive treatment and decision making is guided by patient clinical status and biological tests of the haemostatic function. A key point is the time frame of the clinical process. Therapeutic choices have to be done as fast as possible to minimize bleeding consequences on patient haemodynamic and physiological status. Conventional coagulation test results availability time usually exceed 45' after blood drawing. In such situation, the results may not reflect precisely the coagulation system current state. This downside is often counterbalanced by clinicians empirical choices preceding lab test results knowledge that may conduct to inappropriate treatment, blood product overuse and undue expense. Viscoelastic point of care test may compensate for the limitations of conventional coagulation tests. In perioperative haemorrhage, faster and more precise information about haemostatic function may help for more accurate therapeutic choices. The IMOTEC study aims to compare haemorrhage management following cardiac surgery using conventional blood coagulation tests or thrombo-elastogaphic point of care test. Primary endpoint is a cost utility analysis of the technology and secondary endpoints include blood component transfusion, postoperative bleeding , thoracic re-intervention, postoperative infection (any cause), organ failure, in hospital length of stay and death.

Total knee arthroplasty (TKA), the definitive treatment of osteoarthritis, is often associated with excessive postoperative bleeding due to increased fibrinolysis. Hence, the objective of the proposed study is to determine the role of topical application of tranexamic acid (TA), an anti-fibrinolytic agent, into the knee joint just before closure during TKA to reduce perioperative bleeding. The investigators' hypothesis is that in patients undergoing unilateral primary TKA, intraoperative application of 1.5 g or 3.0g topical TA into the knee joint before closure reduces perioperative bleeding as depicted by a decrement in the maximal drop in hemoglobin concentration following surgery. This proposal describes a randomized, double-blinded, placebo-controlled clinical trial with three arms. The primary outcome is the extent of the postoperative reduction in hemoglobin levels. Secondary outcomes will include transfusion requirements, hospital stay, joint functionality, quality of life and safety of using topical TA. Topical application of TA is a novel intraoperative approach that has not been used or studied in TKA. However if it is effective, it will directly reduce postoperative intra-articular bleeding without subsequent systemic absorption and thromboembolism. In addition, the reduction in microvascular intra-articular bleeding will lead to less pain and infection rates as well as improved surgical functional outcomes.

The purpose of this study is to determine whether the use of ROTEM, during spinal surgery is effective on diminishing the total blood loss and the risk of Allogenic Transfusion of Blood Products vs control cases without ROTEM assessment.

Bleeding is a frequent complication during surgery. The peri-operative administration of blood products, including packed red blood cells, thrombocytes and fresh frozen plasma (FFP), is often deemed necessary. Therefore the transfusion of allogenic blood products mandates strategies to optimize the clinical decision to transfuse. The decision to administer FFP is usually made in the absence of any data. Point of care testing of prothrombin time ensures that a major parameter of coagulation is readily available. The test is fast, easy to perform, inexpensive and may enable physicians to rationally determine the need for FFP. Objective of the study is to determine the effectiveness of point of care coagulation testing of prothrombin time to reduce the administration of FFP.

The objective of this research is to compare the effect of irrigation during impacted mandibular third molar surgery, with normal saline of 25 ± 2 ° C and 37 ± 1 ° C for control and experimental sides, respectively.

Middle ear surgeries utilizes microscope in a narrow field. They are better performed under controlled hypotension, to minimize bleeding and improve surgical field visualization and hence improve results.Head-up or anti-trendelenburg position influences intraoperative bleeding by generating regional ischaemia in sites elevated above the level of the heart. Also by augmenting the effect of vasodilators through pooling of blood in dilated veins.

The aim of the work is to compare the efficacy of preoperative IV tranexamic acid and rectal misoprostol in reducing blood loss in the elective cesarean section. Research question: In women undergoing elective cesarean section, is preoperative administration of IV tranexamic acid better than rectal misoprostol in reducing blood loss?
