The effect of using tablet computer on surgical stress: A single-blinded randomized controlled trial

Abstract

Introduction: The purpose of our study was to evaluate the effects of tablet computer method on children with and without anxiety. The study was designed as a prospective single-blinded randomized controlled trial.

Materials and methods: The population of the study were 300 patients between the ages of 4 and 10 years old who were scheduled for their first elective surgery for phimosis-inguinal hernia-hydrocele-undescended testis-hypospadias. The initial anxiety scores of the patients were evaluated using modified-Yale Preoperative Anxiety Scale (mYPAS). Group-Midazolam, Group-Tablet, Group-Control were formed by applying randomization to the patients. The anxiety levels of the patients were evaluated in the waiting room using mYPAS after 0.5 mg/kg midazolam or tablet computer. Patient anxiety about separation from their families was evaluated with Parental Separation Anxiety Scale (PSAS), and reactions to the anaesthesia mask were evaluated with Mask Acceptance Scale (MAS). Also, the time spent by the patients in the Post-Operative Care Unit (PACU) was evaluated. Post-Hospitalization Behavior Questionnaire (PHBQ) scores of the patients were determined by the anesthesiologist one week after the surgery.

Results: The study compared the anxiety levels in groups. There were significant differences in the post-anxiolytic-mYPAS-scores and percentages of decrease from the preoperative baseline measurements (p < 0.001 and p < 0.001). There were significantly more children who were easily separated from their parents (PSAS-Score 1) in Group-Midazolam (p < 0.01). The children in Group-Midazolam also accepted the masks more readily (MAS-Score 1) than other (p < 0.001). Differences in the duration of the recovery time and mean PHBQ-scores between the groups were also significant (p < 0.001 for each). For children with anxiety, the recovery time for those in Group-Midazolam was significantly longer than other. For children without anxiety (p < 0.001), the duration of the recovery time in Group-Midazolam was also found to be significantly longer than other. The PHBQ-scores of the children in Group-Control with anxiety and without anxiety were significantly higher than other (p < 0.05 for each). Also, there were significant differences in the distribution of the PSAS-scores between the children with and without anxiety. Anxiety had no impact on the distribution of the MAS-scores (p = 0.045 and p = 0.100).

Conclusion: Playing tablet-based games in the preoperative period enabled pediatric patients to be more comfortable while waiting in their rooms, leaving their families, and applying an anaesthetic mask. In pediatric patient with and without anxiety, midazolam separation from the family and accepting the anesthesia mask is easiest in midazolam, second in those who are given a tablet computer.
