Jul 14, 2014 · The J-Tip device utilizes a cartridge of compressed carbon dioxide to drive buffered lidocaine into the skin. However, it does so with a loud "pop," which is why the study included a control arm featuring a sham J-Tip syringe with the compressed gas but no lidocaine, explained Dr. Lunoe of the Medical College of Wisconsin, Milwaukee.
The anesthetic in the J-tip (Figure 1) is made from a mixture of 1% or 2% lidocaine and saline. The liquid components are administered via a plastic injector. Mar 18, 2009 · J-Tip and EMLA were compared in a head-to-head trial examining their efficacy in reducing pain during IV cannulation and placement. 19 Patients aged 7 to 19 years were randomized to receive 1% buffered lidocaine 0.25 mg via J-Tip (n = 57) or EMLA 2.5 g (n = 59) prior to cannulation. Pain was rated via visual analog scale scores (1-10) at the Nov 20, 2017 · We compared a needle‐free jet‐injection system (J‐Tip) with 1% buffered lidocaine to topical anesthetic (TA ) cream for local anesthesia in infant LP s. Methods. This was a single‐center randomized double‐blind trial of J‐Tip versus TA for infant LP s in an urban tertiary care children's hospital emergency department. Many providers may not be familiar with the "J-Tip" (National Medical Products Inc, Irvine, CA) which is a needle-free jet injection system that uses air to push buffered lidocaine into the skin. In theory, it provides quick local anesthesia without a needle, making it an ideal tool to reduce the pain of pediatric venipuncture.
Lidocaine is a local anesthetic (numbing medication). It works by blocking nerve signals in your body. Lidocaine injection is used to numb an area of your body to help reduce pain or discomfort caused by invasive medical procedures such as surgery, needle punctures, or insertion of a catheter or breathing tube.
J-Tip has been primarily used for delivering a standard lidocaine (MPF) or buffered lidocaine solution to numb an area prior to the start of an IV catheter or needle procedure. When used in conjunction with the medication and proper technique, IV starts can be administered with almost zero pain to the patient.
Buffering the pH of the lidocaine solution with sodium bicarbonate can reduce the pain associated with infiltration and increase its duration of action. The pH of plain lidocaine is about 6.3–6.4, but the addition of sodium bicarbonate converts about 50% of the drug to the free base, at a pH of about 8.0 (pKa 7.9).
Jun 02, 2020 · Detailed Lidocaine dosage information for adults and children. Includes dosages for Ventricular Tachycardia, Anesthesia, Ventricular Fibrillation and more; plus renal, liver and dialysis adjustments. Feb 01, 2016 · Children 1–6 years old undergoing venipuncture in an outpatient laboratory were randomized to 1 of 3 groups: (1) intervention: jet injection system with buffered lidocaine (J-Tip, which uses air to push lidocaine into the skin to provide local anesthetic … Based on the findings and experience obtained from this study, we hypothesize that a follow-up study using buffered lidocaine may be able to better reveal the benefits of JNFS.
