Aims and objectives: To examine if adding educational digital video disk to routine education can reduce parental uncertainty and anxiety more if their children undergo congenital heart disease catheterization and when catheterization or post- catheterization complications occur.~Background: Parents experience uncertainty and anxiety when their children undergo conditions mentioned above.~Design: A randomized control-group pretest-posttest design. Methods: In a teaching hospital, 50 fathers and 50 mothers whose children (n=50) underwent first elective catheterization for congenital heart disease were randomly divided into group 1: 25 fathers and 25 mothers receiving routine education plus digital video disk before catheterization; and group 2: 25 fathers and 25 mothers receiving routine education before catheterization. Between groups, parental uncertainty and anxiety levels were compared (1) before education, (2) after education (before catheterization) and (3) on the discharge day (after catheterization). Among mothers whose children had catheterization or post- catheterization complications, the effect of watching the digital video disk on uncertainty and anxiety at discharge day was evaluated.
To examine if adding educational digital video disk to routine education can reduce parental uncertainty and anxiety more if their children undergo congenital heart disease catheterization and when catheterization or post- catheterization complications occur. We want to know, compared to only routine education, if adding digital video disk could decrease parental uncertainty or anxiety more or not.
