Children Under General Anaesthesia
Conditions
Brief summary
Children develop anxiety during the induction of anaesthesia and video-games might reduce or alleviate it. The investigators intend to conduct a clinical trial to study the effect of tablet-based interctive games on alleviating preoperative anxiety.
Detailed description
It is estimated that 50% of children may suffer preoperative anxiety. They have a higher risk of generating postanesthetic delirium and behavioral changes in the postoperative period up to 67% of cases. For the management of preoperative anxiety there are pharmacological and non-pharmacological treatments. Within the first group there's the use of benzodiazepines of short half life like midazolam, however, the use of this medication is not exempt of risks such as paradox reactions, respiratory depression, among others. This is why the non pharmacological mesures have taken force and every day there is more evidence regarding its effectiveness. There are no reports in Chile or latin america regarding the use of this tools, this is why the investigators designed this study to prove the effectiveness of audiovisual distraction measures in reducing preparatory anxiety compared to premeditation with midazolam.
Interventions

Masking description
Anxiety will be determined by using a video recording of the child, which will be assessed by psychiatric
Intervention model description
Tablet Group: They'll receive a tablet with content adapted to every group. It will be divided into 4 groups (2-4 years, 4-6 years, 6-8 years and 9-10 years). The first one will receive cartoons, the second will also have games; for the other two groups will be assigned appropriate video games depending on the age. Midazolam group: They'll receive 0,5mg/kg oral or it's equivalent in rectal administration 30 minutes to one hour prior to transfer to the theater. This patients will not be able to have contact with audiovisual devices.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Short version of the modified Yale Preoperative Anxiety Scale(mYPAS-SF) | 6 hours | Difference between the measurement of the mYPAS-SF applied in the preoperative time and prior to induction. The scale has 18 items in 4 categories. Maximum score is 100 points. The higher the score, the greater the anxiety. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Cooperation with the induction | 30 minuts | Scale with 10 items, 1 point for each one. 0 points shows an induction with perfect cooperation. This scale will be applied at the moment of the induction by the anesthesiologist |
| Changes in postoperative behavior | 10 days | The Post Behavioral Behavior Change Questionnaire (PHBQ) will be applied at the postoperative surgical control (7-10 days after the intervention). This survey will be applied by people trained by the hospital's pediatric psychiatry team The higher the score, the more behavioral changes in the postoperative period |
| Emergence delirium | 1 hour | In the post-anesthesia recovery unit, the Emergency Delirium Scale for Pediatric Anesthesia (PAED) will be applied every 15 minutes during the first 30 minutes of their stay in the unit. Score goes from 0 to 20. Scores greater than 10 is considered as delirium. |
| Parents Satisfaction | 10 minuts | A gradual scale will be applied to the parents of the patient upon discharge from hospital. |
