Moorjani GR et al. - 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 reduces hemorrhage and improves the safety and outcome. Methods
Aim was to investigate the relationship of needle control to tissue trauma and hemorrhage during syringe procedures
47 subjects with a palpable knee effusion underwent needle and syringe aspiration
Subjects were randomized to the conventional syringe or a safety technology, the reciprocating procedure device (RPD)
Pain was measured with the Visual Analog Pain Scale (VAPS)
Cell count, crystal examination, culture, and aspirated fluid volume were determined
Red blood cell (RBC) counts were used to measure blood in aspirated fluid
Results
Patient pain during the syringe procedure significantly predicted blood (RBC) in aspirated fluid
When compared to the conventional syringe, the RPD safety device reduced blood in aspirated fluid by 66.7%
It also reduced patient pain by 73.9%, and improved fluid aspirate yield by 132%
