Filter by:This is a special access protocol that will allow physicians access to aprotinin during the temporary marketing suspension. The program will provide aprotinin for treatment of surgical patients undergoing coronary artery bypass graft (CABG) surgery requiring cardiopulmonary bypass (CPB) who are at increased risk of bleeding and transfusion when, in the opinion of the treating physician, the patients require it, there is no acceptable alternative therapy, and when there is a clearly favorable benefit-risk for the drug in that individual patient.
BACKGROUND. Arterial access site complications remain the most frequent adverse events after percutaneous transluminal procedures. We investigated the safety and efficacy of the pro-coagulant wound dressing Neptune Pad ® compared to conventional manual compression for access site management after peripheral percutaneous interventions. METHODS. We enrolled 201 consecutive patients and randomly assigned patients for Neptune Pad ® (n=100) vs. conventional manual compression (n=101). Patients were followed clinically until hospital discharge and by duplex ultrasound at 24 hours postprocedure for occurrence of access site complications. Time-to-hemostasis and time-to-ambulation were recorded, patients´ and physicians´ discomfort were measured using a visual analogue scale.
Study has been completed and is in the data analysis and manuscript writing phase of the project.
The purpose of this study is to determine if aspirin is associated with bleeding complications following a single tooth extraction
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.
The objective of this study is to evaluate the safety and efficacy of aprotinin as compared to placebo, in reducing the need for blood transfusion in adult subjects undergoing elective spinal fusion surgery involving 3 to 7 vertebral levels with instrumentation
There has been continuing debate about whether use of hetastarch for volume replacement in coronary artery bypass surgery [CABG] increases the risk of postoperative bleeding. A recent meta-analysis of hetastarch use in on-pump CABG concluded that use of hetastarch in these procedures is associated with increased risk, but the safety of hetastarch use in off-pump procedures remains unresolved. We designed a double-blinded randomized clinical trial to investigate this question. The study was designed as an equivalence trial. Statistical power calculations were performed taking this into consideration. Sealed assignments from a block randomization table developed prior nto initiation of the trial were unsealed in the operating room. These were used to assign patients scheduled for off-pump CABG to receive either 1 L of hetastarch or 1 L of albumin as part of intraoperative volume replacement. Albumin was used for all subsequent intraoperative and postoperative fluid replacement. The rate of postoperative bleeding was assessed prospectively by monitoring hourly chest tube drainage and number of units of blood products transfused postoperatively in the Intensive Care Unit. Risk was assessed by a Data Safety Monitoring Committee (DSMC) established for this trial. The SAMC was scheduled per protocol to meet after the first 15 subjects (both groups combined) had 1000cc or more of chest tube drainage in the first 12 hours postoperative, and then subsequently either after 15 additional bleeds of this volume or following a schedule set at the discretion of the DSMC. The trial was continued until 156 patients had been recruited. At that time, 78 participants each had been assigned to the hetastarch and albumin groups. DSMC review at that time determined that use of hetastarch is associated with a risk of postoperative bleeding which is greater than the risk associated with use of albumin and the DSMC accordingly halted the trial.
The purpose of this study is to assess if aprotinin (BAYA0128), given intravenously during your surgery, is safe and can help reduce the need for a blood transfusion during bladder surgery.
