Evaluation of Accuvein for Blood Sampling and for Intravenous Catheter Placement in Adult Patients

The objective of this study is to evaluate the effectiveness of Accuvein to facilitate venous blood sampling and placement of peripheral intravenous catheters in adults. This clinical protocol is designed to determine whether using Accuvein increases the ease and efficiency of venous cannulation (as perceived by the operator), decreases the time to effective cannulation, decreases the number of sticks, and decreases the patient's perception of the pain.
