Randomized Controlled Trial
Patient pain and tissue trauma during syringe procedures: a randomized controlled trial.
To investigate the relationship of needle control to tissue trauma and hemorrhage during syringe procedures. ⋯ Inadequate control of needle and syringe during physician-performed syringe procedures is an important cause of trauma to patient tissues resulting in hemorrhage, increased patient pain, and decreased aspirate yield. The RPD -- a safety device that improves needle control and decreases needle trauma to tissues -- reduces hemorrhage and improves the safety, outcome, and aspirate yield of physician-performed syringe procedures.
