Needleless Jet Injected (J-Tip) Lidocaine in Children Undergoing Regional Anesthesia Prior to Knee Arthroscopy

"After sterile preparation, the J-tip injector will be placed on the skin at the selected site of the regional block needle introduction. Firm pressure will be placed with the J-tip injector on the site for the chosen block, the safety ring slid down, the trigger pressed and the tip held firmly on the skin for three seconds. One quarter of a milliliter of one percent lidocaine will be injected with the characteristic pop and hissing sounds inherent to the J-tip injector."

The same initial timeout and sterile prep procedure will be followed for the use of local syringe and 25 gauge needle injection of 1% lidocaine ninety seconds prior to introduction of the regional block needle.
