Effects of anxiety on sedation among pediatric patients undergoing esophagogastroduodenoscopy

초록

We investigated whether the severity of anxiety among children undergoing endoscopy could affect sedation. We prospectively recruited patients under 18 years of age who were scheduled to undergo esophagogastroduodenoscopy (EGD). Baseline anxiety was evaluated using the Spence Children's Anxiety Scale (SCAS). Our analysis considered the type and dose of sedative drugs, degree of sedation, and complications associated with sedation according to the scale score. The mean total SCAS T-scores and each subscale score were significantly higher in the 6-12-year age group. The mean T-score among patients who exhibited irritability during EGD was higher than that among other patients, with significant differences in the Total, Obsessive Disorder, Panic Agoraphobia and General Anxiety subscales. The midazolam doses of children exhibiting irritability were more likely to need higher (p = 0.006). Other sedation-related complications were not associated with the T-scores in each subscale. Total sleep time was not associated with any T-score subscales. Anxiety levels were significantly higher among 6-12-year-olds and children exhibiting irritability. Anxiety was often associated with irritability, difficulties achieving adequate sedation during EGD, and additional sedative drug administration. We recommend higher doses or more potent drugs to facilitate endoscopy for children with high anxiety levels.
