Brief summary

The study's hypothesis is LMX4 cream, a topical anesthetic cream, will reduce the pain of infants undergoing Lumbar Puncture (spinal tap).

Detailed description

Pain of infants will be measured using the Neonatal Facial Coding System by videotaping the infant's face while they undergo the procedure. A comparison between the group that received active drug and the group that received placebo will allow a measurement of the difference, if any, of the pain experienced during the procedure of the infants.

Interventions

DRUGLidocaine Cream 4%

Topical cream, 2g applied under occlusive dressing for 20 minutes prior to the procedure

DRUGPlacebo

inactive placebo without LMX4

Design outcomes

Neonatal Facial Coding System ScoreScore was measured at baseline, upon positioning for the procedure, immediately prior to needle insertion, during needle insertion, 1 minute post-needle insertion, and post-procedure when the infant had recovered from the procedure and was swaddled10 measures of pain, all scored 0 or 1, high score means more pain. No pain would be recorded as zero, maximum pain recorded as 10

Outcome results

Primary

Neonatal Facial Coding System Score

10 measures of pain, all scored 0 or 1, high score means more pain. No pain would be recorded as zero, maximum pain recorded as 10

Time frame: Score was measured at baseline, upon positioning for the procedure, immediately prior to needle insertion, during needle insertion, 1 minute post-needle insertion, and post-procedure when the infant had recovered from the procedure and was swaddled
