Long Term Memory Preoperative Preparation Reduce Post Operative Behavioral Change

Study Overview
=================
Brief Summary
-----------------
The study is designed to test the hypothesis that long term memory created by preoperative video information can reduce the incidence of post operative behavioral changes.

Detailed Description
-----------------
Emergence agitation (EA) and Post operative behavioral change (PHC) are unpleasant experiences occurred in children after general anesthesia (GA). Previous study reported that the patient who had marked EA tended to have new-onset of postoperative maladaptive behavioral changes.Both pharmacologic and non pharmacologic interventions such as preoperative video information, hand held video games were used to reduce preoperative anxiety, EA and Post operative behavioral changes. In term of memory creation, short term memory (STM) was created. Later that the formation of memory trace requires time, and that this trace remains fragile until the long term memory formation process has been completed. In this study, the investigators hypothetize that long term memory created by preoperative video information can reduce the incidence of post operative behavioral changes.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Incidences of post operative behavioral changes | Use PHBQ (post operative behavioral questionnaire) Postive for postoperative behavioral change: 10% change from baseline sum score | up to3 months post operative period | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Incidences of Emergence agitation | PAED scale, PAED scale > 10 will be classified as positive for emergence agitation | evaluate PAED scale in the first 5 minutes after patient arrive PACU | 
| Parental's anxiety level at induction | STATE trait anxiety test: 10% change from baseline sum score will be classify as significant change | Evaluate 15 minutes before start anesthesia induction | 
| Child's anxiety level at induction | mYpas scale: 10% change from baseline sum score will be classify as significant change | mYpas will be evaluated immediately after the patient arrives into the operating room |
