6 Clinical Trials for Various Conditions
The investigators aim to compare the standard bulb aspirator with that of a nasal oral aspirator. The hypothesis is that use of a nasal oral aspirator is more effective at removing nasal secretions in the treatment of bronchiolitis as measured by a predicted 50% decrease in the rate of unscheduled bronchiolitis return visits. The primary endpoint will be the number of unscheduled bronchiolitis return visits; secondary endpoints will include measurements of oral intake, respiratory relief, parental device preference and adverse events.
The purpose of this study is to measure the performance characteristics for the collection, fixation and transportation of clinical nipple aspirate fluid (NAF) specimens of the ForeCYTE Breast Aspirator across 3 independent labs and the National Reference Laboratory for Breast Health (NRLBH). The study hypothesis is that each lab will have a specimen acceptability rate of at least 90%. If it is assumed that the true level of acceptability testing is approximately 96%, then the lower bound of a one-sided 95% confidence interval is expected to be at least 90%.
The embolisation of fat and bone marrow during long bone instrumentation is a well-known complication of major joint replacement surgery. Clinically significant venous thromboembolic disease, cardiopulmonary dysfunction,cerebral emboli, and death have all been described. Because the intravasation of medullary contents is caused by increased pressure during canal instrumentation, the use of the Synthes RIA (Reamer-Irrigator-Aspirator), a negative pressure-irrigated high-speed reamer, may result in a lower incidence of embolism. This controlled clinical trial will evaluate the utility of the RIA in reducing the frequency and severity of embolic events as detected by intraoperative transesophageal echocardiography (TEE) and transcranial Doppler (TCD) during total knee arthroplasty (TKA) surgery.
The purpose of this study is to find out if the cells in bone graft samples collected using a reamer are similar to the cells in bone graft samples collected using the iliac crest bone graft method.
The purpose of this study is to compare the quantity of fat that is released into the venous system (blood) by reaming the femoral canal during intramedullary nailing of the femur using two different reaming systems.
This study is to determine the composition of bone graft harvested using the RIA system in 16 orthopaedic trauma patients between age 19 and 65 who have sustained a fracture or non-union requiring bone grafting. The patients will be followed to assess clinical outcomes and associated pain.
