A Pilot Study of Ketamine versus Midazolam/Fentanyl Sedation in Children Undergoing GI Endoscopy
Figure 2
Analysis of covariance of percent time nonvocalizing on years of age, adjusted for sedation type. Ketamine sedation is represented by closed circles (●) and a solid regression line (—) while medazolam/fentanyl is represented by open circles (∘) and a dotted regression line (). Ketamine sedation is associated with a greater percentage of time nonvocalizing compared with medazolam/fentanyl (), independent of the effect of age. The interaction of sedation type with age was not statistically significant ().
