A team from Tennessee and Ohio, USA, evaluated the relationship between children's knowledge of esophagogastroduodenoscopy (EGD) and anticipatory anxiety, procedural distress, and the nature of postprocedural recall and evaluations.
The researchers enrolled 100 patients, aged 8 to 17 years, in the study. Each completed self-report measures of knowledge and anxiety before EGD.
Parents completed a self-report measure, assessing how they prepared their children.
In addition, nurses and trained observers completed observational ratings of distress.
Children's recall and evaluation of the procedure were assessed by self-report 1 hour after the procedure and by telephone that evening.
Most children knew about the major components of EGD.

Children with greater knowledge experienced less distress and reported that they would be less anxious and upset when undergoing future EGDs.
Those with greater anticipatory anxiety exhibited more procedural distress.
The researchers found that the children's distress varied by the phase of the procedure. Those who were more distressed during intravenous line insertion experienced greater distress during esophageal intubation and the endoscopic examination.
It was found that approximately 20% of patients reported at least some memory of the procedure, even at the end of the day.
Children with greater recall reported greater aversion and a more negative attitude toward future EGDs.
Author R. L. Claar, of the Vanderbilt University School of Medicine, Nashville, Tennessee, said on behalf of colleagues, "This study provides information about children's distress during EGD, and the effects of conscious sedation on patients' memories and attitudes toward future procedures."
"The study indicates that preparation before EGD may reduce patient distress," it was concluded.
