Needle-Free Lidocaine Injection vs Traditional Local Anesthesia in Infant Lumbar Puncture

We hypothesize that the J-Tip needle-free jet-injection system offers comparable pain control and greater provider satisfaction due to its less invasive nature compared to traditional needle infiltration of 1% lidocaine in infants undergoing lumbar punctures. Our aim is to evaluate the efficacy and feasibility of different local anesthetic techniques in the ED setting by comparing traditional lidocaine needle infiltration with J-tip.
