Reciprocating Medical Devices - a Study of a New Safety Device
Randomized Controlled Trial of the Reciprocating Procedure Device Versus the Conventional Syringe in Syringe-and-Needle Procedures

The study design is a randomized study to directly compare the performance and the outcome of syringe and needle procedures with a standard syringe or the new reciprocating procedure device (RDP), which is a type of safety syringe. Over a 5 year period, 820 subjects who require and assent to a syringe and needle procedure for their usual and customary care will be randomized to either a conventional syringe or the RPD. The RPD is designed to be safer, faster, less painful, and more effective for the patient, and the mechanics of the RPD are intended to provide the physician with better needle control, resulting in less needle trauma to patient tissues, and thus, reduced bleeding and pain for the patient. This clinical trial will address whether the RPD is indeed superior to the conventional syringe for shots, injections, and needle procedures, and whether it is a safer, less painful syringe.

  • BACKGROUND

The syringe is an ancient device designed principally to inject medications. However, because of the inherent biomechanics of the human hand and the interaction of the hand with the piston, the syringe is very stable and easily controlled the injection phase, but is extremely unstable and difficult to control in the aspiration phase. New reciprocating technology that accommodates the biomechanics of hand function has great promise of improving the stability and safety of hand-held devices, including procedure syringes.

* EXPERIMENTAL DESIGN AND METHODS

The study design is a randomized study to directly compare the performance and the outcome of syringe and needle procedures accomplished either with a standard syringe or the new reciprocating procedure device (RDP). Over a 5 year period, 820 subjects who require and assent to a syringe procedure for their usual and customary care will be randomized to either a conventional syringe or the reciprocating syringe. The following syringe procedures will be studied: 1) local anesthesia, 2) centesis (arthrocentesis, paracentesis, thoracentesis, amniocentesis, pericardiocentesis), 3) aspiration and puncture (aspiration of bursa, cyst, abscess, shunt, bone marrow, and other syringe aspiration procedures), 4) injection of a therapeutic or diagnostic substance into a joint, bursa, vessel, or other body structure, 5) fine needle biopsy with syringe vacuum of a mass or tissue, 6) irrigation procedures (wound, bladder, and other irrigation procedures), and 7) vascular access (introduction of a wire, catheter, or sheath into a blood vessel).

In a subject with multiple individual procedure sites, or requires multiple separate biopsies, each will be randomized between the two syringes, and each biopsy or fluid sample will be analyzed separately (as is medically appropriate). The physicians who will perform the syringe procedures will be those physicians who usually perform the syringe procedures and are credentialed to do so. Outcome data collection will occur first by one of the investigators observing the procedure and collecting the data by real time interview and by chart review including cost analysis. Outcome data will include effectiveness (preprocedural pain, pain at 2 weeks post procedure, and pain at 6 months postprocedure), procedure time, patient pain, operator satisfaction, trauma to tissues, complications, diagnostic yield, overall medical care costs and hospital stay. Retrospective review of 30 charts of the device used clinically has also been approved (2006). Analysis of data will be performed by a statistician blinded to treatment group.

*SIGNIFICANCE: The proposed study will be the first to study the clinical performance characteristics of a medical device that incorporates the new reciprocating technology designed to take advantage of the inherent biomechanical stability characteristics of the human hand. The preclinical studies presented in the preliminary data demonstrate markedly enhanced device performance characteristics, and much greater control and stability, strongly suggesting that reciprocating devices will be safer, more effective, more economical, and provide better patient outcomes.

  • Device: conventional syringe - BD Ref 309604
  • Experimental: Reciprocating Procedure Device (RPD)- The RPD is used to performed the syringe and needle procedure and outcome (effect of procedure (pain scores at 2 weeks and 6 months compared to preprocedural pain scores), and procedural pain (pain scores during procedure) are determined). It is hypothesized that the RPD will be more effective (reduced pain scores at 2 weeks and 6 months) and less pain (reduced procedural pain scores) compared to the same procedure with the conventional syringe.
  • Active Comparator: Conventional Syringe - The conventional syringe is used to performed the syringe and needle procedure and outcome (effect of procedure (pain scores at 2 weeks and 6 months compared to preprocedural pain scores), and procedural pain (pain scores during procedure) are determined). It is hypothesized that the RPD will be more effective (reduced pain scores at 2 weeks and 6 months) and less pain (reduced procedural pain scores) compared to the same procedure with the conventional syringe.
