A Needle-Free Injection System (INJEXTM) with lidocaine for epidural needle insertion: A randomized controlled trial

摘要

Objectives: Local anesthetic infiltration is also a process of a painful process itself. INJEXTM technology, known as “Needle-free” drug delivery system, was designed for reducing the pain associated with cutaneous procedures. We conducted a prospective, randomized trial to evaluate the application of lidocaine with INJEXTM system and 27-gauge needle.Methods: A total of 60 consecutive patients were allocated to receive either INJEX group or 27-gauge needle group. Local anesthetic infiltration was applied two minutes before epidural needle insertion.Results: Mean VAS, at the time of local anesthetic injection was 0 for group I and 2 for group II. When the effect of epidural needle insertion was compared, the mean VAS score was one versus two for Group-I versus Group-II, respectively. Lidocaine applied with the INJEXTM system before epidural needle insertion significantly reduced the intensity of pain during that procedure and was least effective the lidocaine applied with the 27-gauge needle and patients felt less pain during at the time of local anesthetic injection in Group-I.Conclusion: Needle-free delivery of lidocaine is an effective, easy to-use and noninvasive method of providing local anesthesia for the epidural needle insertion.doi: http://dx.doi.org/10.12669/pjms.323.9174How to cite this:Gozdemir M, Demircioglu RI, Karabayirli S, Sert H, Muslu B, Usta B, et al.
