Overview
Brief Summary
The purpose of this study is to determine whether bilateral infraorbital and infratrochlear nerve block in patients undergoing septorhinoplasty are effective in preventing emergence agitation.
Detailed Description
Emergence agitation is a postanesthetic phenomenon characterized as confusion, disorientation and violent behavior. Although its etiology is not well understood, risk factors associated with the condition include pain and ENT (ear, nose and throat) surgery. Bilateral infraorbital and infratrochlear nerve block in patients undergoing septorhinoplasty is effective in treating postoperative pain. The investigators have designed this study to evaluate the effect of infraorbital and infratrochlear nerve block on emergence agitation in patients undergoing septorhinoplasty.

Outcomes
Primary Outcomes
Emergence agitation
Time Frame: 2 hours after surgery
Emergence agitation is measured by Riker Sedation-Agitated Scale (RASS) and is defined as RASS=5-7
Secondary Outcomes
- Pain intensity(2, 8, 24, 48 hours after surgery)
- Patient satisfaction(48 hours after surgery)
