Overview
Brief Summary
The numeric rating scale (NRS), one of the most widely used pain scales in clinical practice, although convenient, is often subject to bias because it requires abstract thinking from both the patient and the evaluator. Compared to numbers, traumatic pain, when visualized appropriately, has potential advantage as a means to indicate and communicate the severity of pain. Given that they are standardized in terms of body parts, wound size, and bleeding volume, illustrations of traumatic pain along with external somatic stimuli that caused it can be used to serve as effective visual anchors to supplement a pain scale by giving more concrete information to the patient. The purpose of this study is to develop Seoul National University Illustrated Pain Scale(SNUIPS) using pictures of traumatic pain, and verify the validity and effectiveness of this scale in comparison with those of NRS.

Outcomes
Primary Outcomes
Patient Satisfaction of Postoperative Pain Management
Time Frame: 48 hours after surgery
Survey among patients on their level of overall satisfaction on postoperative pain management
Postoperative Pain Scores (NRS)
Time Frame: 48 hours after surgery
Self-reported pain intensity based on numeric rating scale evaluated after 48 hours after surgery for assessment of sensitivity to change. Each item is scored from 0 to 10 (0 = no pain; 10 = worst imaginable pain).
Postoperative Pain Scores (SNUIPS)
Time Frame: 48 hours after surgery
Self-reported pain intensity based on Seoul National University Illustrated Pain Scale evaluated after 48 hours after surgery. Each item is scored using illustrations that corresponds to 0-10 levels of traumatic pain, beginning from 'no injury and/or pain' to 'causalgia'.
Postoperative Consumption of Patient-Controlled and/or Rescue Analgesics
Time Frame: 48 hours after surgery
Amount of analgesics consumed through intravenous patient-controlled analgesia and/or administration of rescue analgesics
Understandability of Pain Scales
Time Frame: 48 hours after surgery
Survey among patients on understandability pain scales
Convenience of Pain Scales
Time Frame: 48 hours after surgery
Survey among patients on convenience of pain scales
