Clinical Trial Summary

Comparison of anesthetic efficacy of Lidocaine (4%), Epinephrine (0.1%), and Tetracaine (0.5%) topical gel (LET) applied three times for 10 minutes each time vs. once for 30 minutes prior to suturing simple lacerations in children aged 7-17 years.

Description:

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Visual Analog Scale Pain Score	Pain score self-rated by patient on 100m Visual Analog Pain scale, minimum value 0, maximum value 100, higher scores equal more pain (worse outcome)	Immediately on placement or attempt at placement of first suture
Secondary	Need for Additional Local Anesthetic	Need for additional infiltrated local anesthetic (lidocaine)	At any time during suturing procedure, time frame is duration of procedure, generally 10-20 minutes, less than one hour. Determined by chart review immediately after procedure completion.
