This double-blind, randomised, placebo-controlled study compared the delivery of 0.5 mg lidocaine, 0.25 mg lidocaine and placebo in 144 paediatric patients undergoing venepuncture through a single-use, needle-free drug delivery system (ALGRX 3268, AlgoRx Pharmaceuticals, Secaucus, New Jersey, USA). This system administers powdered drug into the epidermis for inducing local anaesthesia in 2–3 min. Pain scores were measured using the Faces Pain Scale Revised (FPS-R) and Visual Analogue Scale (VAS).
