Syringe size: does it matter in physician-performed procedures?

Area of Science:

• Medical Devices
• Patient Safety
• Procedural Accuracy

Background:

• Syringe size is a critical factor in physician-performed procedures.
• Needle control directly impacts procedural outcomes and patient safety.

Purpose of the Study:

• To investigate the hypothesis that syringe size influences needle control during physician-performed procedures.
• To evaluate the impact of syringe size on unintended needle movement and patient pain.

Main Methods:

• Quantitative needle-based displacement method used to assess control with 1- to 20-mL syringes and reciprocating procedure devices (RPDs).
• 320 clinical syringe procedures were randomized between conventional syringes and RPDs (3- and 10-mL sizes).
• Patient pain was measured using the Visual Analog Pain Scale (VAPS).

Main Results:

• Increasing syringe size correlated with significant unintended forward penetration (r(2) = 0.97) and retraction (r(2) = 0.97).
• Two-handed syringe operation demonstrated superior control compared to one-handed operation (P < 0.001).
• The RPD significantly reduced unintended penetration (52.3%), retraction (56.8%), and patient pain (54.7%) during one-handed operation.

Conclusions:

• Smaller syringe sizes and two-handed operation enhance safety and control with conventional syringes.
• The reciprocating procedure device (RPD) offers a significant safety improvement for one-handed syringe operations.
• Implementing these strategies can minimize procedural risks and improve patient comfort.
