NCT ID: NCT02778880

Last Updated: 2020-09-01

Results Overview

A VAS score is a self reported pain score of 0-100 millimeters (0 = no pain; 100 = worst possible pain). A decrease in a VAS score indicates a decrease in pain severity.

Participant Flow

This clinical trial took place at a tertiary care children's hospital emergency department from March 2016 to February 2017. The study sample was identified through an established triage process identifying children with an acute painful extremity injury. These patients were ages 8-17 years with a visual analog scale (VAS) score greater than 35 mm.

PRIMARY outcome

Timeframe: 30 minutes after study medication

Population: One patient in the ketamine group did not have a baseline pain score documented and four patients withdrew from the study (1 in the ketamine group, 3 in the fentanyl group), resulting in 43 patients randomized to the ketamine group and 42 patients randomized to the fentanyl group included in the primary outcome analysis.

A VAS score is a self reported pain score of 0-100 millimeters (0 = no pain; 100 = worst possible pain). A decrease in a VAS score indicates a decrease in pain severity.

The University of Michigan Sedation Scale is a valid and reliable tool that allows for rapid assessment of the depth of sedation in children. It is a simple observational tool that assesses the level of alertness on a five-point scale. It has been validated in children and has shown to have significant inter-rater reliability. Score is 0-4 (0 = awake and alert; 1= minimally sedated; 2 = moderately sedated; 3 = deeply sedated; 4 = unarousable)
