 This study is designed to evaluate userphysician preference as it relates to use of a 510k cleared vascular access and catheter device compared with conventional needlecatheter vascular access devices, in terms of first stick success rates, dwell time, device-related vascular complications and adverse events and overall user and patient satisfaction. As noted above, the study is designed to formally test the hypothesis that the AccuCathTM System will exhibit superiority in terms of the rate of successful first attempt peripheral IV placement, higher completion of therapy, fewer complications, longer dwell times and higher user satisfaction compared to conventional intravenous catheters.
