Subcutaneous lidocaine delivered by jet-injector for pain control before IV catheterization in the ED: The patients' perception and preference

To evaluate patients' perceptions and preferences concerning pain control during intravenous (IV) catheterization, a sample of 50 adult patients received subcutaneous lidocaine (0.2 mL 1%) by jet injector, or no anesthetic with a sham injection before IV catheterization. Visual analog scale (VAS), pain intensity score (PIS), and adverse reactions were recorded. A significant difference existed in the scores of patients who received lidocaine versus those who did not VAS (P <.001) PIS (P <.004). Patients' receiving lidocaine via jet-injector experienced more minor and potentially preventable adverse effects such as mild bruising and trauma to the veins. Patients in both groups (84% overall) preferred local anesthesia based on this experience. Using the jet-injector to provide local anesthesia before IV catheterization in the ED is effective, fast, and does not require sharps disposal and handling precautions.
