Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Lidocaine is a local anesthetic that stabilizes neuronal membranes by inhibiting sodium ion influx, thereby blocking initiation and conduction of nerve impulses.
PEDIATRIC LTA KIT contains lidocaine, tetracaine, and epinephrine. Lidocaine and tetracaine are amide and ester local anesthetics, respectively, that block voltage-gated sodium channels, preventing nerve impulse propagation. Epinephrine is a sympathomimetic that causes vasoconstriction, prolonging local anesthetic effect and reducing systemic absorption.
1-1.5 mg/kg IV bolus over 2-3 minutes, followed by continuous IV infusion of 1-4 mg/min for ventricular arrhythmias; maximum 3 mg/kg (or 200-300 mg) over 1 hour.
Not applicable. Pediatric LTA Kit is a topical lidocaine/tetracaine patch for dermal anesthesia. Adult dose: apply one patch to intact skin for 20-30 minutes prior to procedure; remove prior to procedure. Maximum 3 patches per session. Not for systemic use.
