• Conditions: Postoperative, Pain
• Interventions: Other: placebo patch applied; Other: 5% lidocaine patch

• Registration Number: NCT01485939
• Lead Sponsor: Seoul National University Hospital

Detailed Description

* The 5% lidocaine patch have been approved for the treatment of postherpetic neuralgia.

* The investigators hypothesized that application of a 5% lidocaine patch would be associated with reduced pain scores, pain controlled drug(opioids, NSAID) in post operative period.
