Trial Outcomes & Findings for Topical Amethocaine Gel for Intramuscular Injection in Term Neonates (NCT NCT00267111)

NCT ID: NCT00267111

Last Updated: 2024-07-30

Results Overview

The presence or absence of 3 facial actions (brow bulge, eyes squeeze and deepening of the nasolabial furrow) were scored in 2 second intervals for the first 20 seconds (or less if the phase lasted \< 20 seconds) of each procedure phase from the videotapes by a trained research assistant. The data were then collapsed for each facial action into the percentage of time the infant expressed the action. An overall pain score was computed by summing the percentage scores for the three facial actions and then dividing by three. The score ranged from 0% to 100% with higher values suggesting more pain.

SECONDARY outcome

Timeframe: During the entire procedure

Population: Intention to treat analysis

Parents and nurses were asked to assess the infant's pain response during the procedure using Visual analogue scale (VAS) on an unmarked horizontal 10 cm continuous line where 0="no pain" on the left side and 10="worst possible pain" on the right side. Parents and nurses were trained to use the VAS prior to the IM injection.
