A study in children aged 8-18 years to assess whether the J-Tip® device is feasible, safe and acceptable for reducing pain during intravenous cannulation compared with standard care.

A two-arm feasibility randomised control trial (RCT) in children aged 8-18 years evaluating the feasibility, safety and acceptability of the J-Tip® device compared with standard care for peripheral intravenous cannulation (PIVC), with child-reported pain as the primary clinical endpoint for a future phase II trial.

Brief summary

This study will compare a needle-free device (J-Tip®) with standard care (topical numbing cream) in children aged 8-18 years requiring IV cannulation. The aim is to determine whether a larger trial is feasible by assessing recruitment, study processes, safety, and acceptability. Children's pain during cannulation will also be measured to inform a future trial testing whether the J-Tip® reduces pain.

Interventions

The intervention is the intradermal administration of a single 0.25 mL dose of 1% lidocaine using the CO2-powered J-Tip® needle-free device to provide local anaesthesia prior to peripheral intravenous cannulation (PIVC). It is delivered face-to-face on an individual basis by a registered nurse with specialist PIVC insertion skills, immediately before cannulation in children aged 8-18 years. The intervention is provided once per cannulation episode within a tertiary paediatric hospital setting. F

The intervention is the intradermal administration of a single 0.25 mL dose of 1% lidocaine using the CO2-powered J-Tip® needle-free device to provide local anaesthesia prior to peripheral intravenous cannulation (PIVC). It is delivered face-to-face on an individual basis by a registered nurse with specialist PIVC insertion skills, immediately before cannulation in children aged 8-18 years. The intervention is provided once per cannulation episode within a tertiary paediatric hospital setting. For application, the J-Tip® device is positioned perpendicular to the skin at the selected cannulation site and activated to deliver 0.25 mL of 1% lidocaine via a high-pressure stream into the intradermal/subcutaneous tissue without the use of a needle. Following successful administration, PIVC insertion proceeds according to routine clinical practice. Fidelity to the intervention is monitored through protocolised staff training and procedural checklists documenting device preparation, site selection, dose administration, and adherence to the intervention protocol
