Information for Patient Controlled Analgesia Device

Study Overview
=================
Brief Summary
-----------------
This study is aimed to show the effect of information method on properly usage of the patient controlled analgesia(PCA) device

Detailed Description
-----------------
Postoperative pain is still a challenge for anesthesiologist. Patient controlled analgesia is an effective method for postoperative pain management. However, most of the patient can not use the device properly. The important cause of inabilities about device usage is insufficient information.In the patient information, visual, oral or written communication methods can be chosen. However, which method is suitable for our patient group is not clear.This study is aimed to show the effect of information method on properly usage of the patient controlled analgesia(PCA) device

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Pain Score | Numeric rating scale (0 to 10) will be used for postoperative pain score | At postoperative 24th hours. | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Postoperative analgesic consumption | Total opioid dosage will be recorded | Up to the postoperative 24th hours. | 
| PCA device usage | The number of demand dose | During postoperative 24 hours | 
| PCA device demand dose duration | The duration of the patients' demanding dose | During postoperative 24hours | 
| Patient's satisfaction | The numeric rating scale (0 to 10) will be used. In this scale 0 will be the worst, 10 will be the best satisfaction. | At the postoperative 24th hours | 
| The change of the postoperative pain score | Numeric rating scale (0 to 10) will be used to evaluate the pain score. The change in this score during postoperative 24 hours will be calculated.(the first score will be extracted from the last score) | Up to the postoperative 24th hours. |
