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
Topical cream, 2g applied under occlusive dressing for 20 minutes prior to the procedure
inactive placebo without LMX4

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Neonatal Facial Coding System Score | 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 | 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 |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Time of Procedure | Infant's stay in the Emergency Department | Time, measured in minutes, required to complete procedure from infant's presentation to the Emergency Department |
| Percentage of Procedures With Success | During patient's Emergency Department Stay | Whether the Lumbar Puncture resulted in recovery of spinal fluid that could be sent for usual testing |

Outcome results
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
