Anesthetic efficacy of eutectic prilocaine-lidocaine cream in pediatric oncology patients undergoing lumbar puncture

Ann Pharmacother. 1996 Nov;30(11):1235-7. doi: 10.1177/106002809603001104.

Abstract

Objective: To evaluate the efficacy of eutectic mixture of local anesthetics 5% (Emla) in reducing pain associated with lumbar punctures in children.

Design: Prospective, double-blind, randomized, placebo-controlled trial.

Setting: University pediatric hospital.

Patients: Eleven pediatric oncology patients (mean age 6.6 y, range 4-16) who underwent 31 lumbar punctures.

Main outcome measures: The analgesic effect was measured by using two methods. The first was a 10-point visual analog scale reported by the patient and the second was an 8-point behavioral pain scale assessed by the nurse who applied the cream.

Results: Emla cream was associated with significantly lower pain scores than those with placebo as measured by the patient when the puncture was successful on the first attempt (2.0 +/- 1.6 Emla group, 3.8 +/- 1.9 placebo group; p < 0.05).

Conclusions: The use of Emla cream may reduce pain substantially only in patients who undergo a successful lumbar puncture on the first attempt.
