Effect of Ketamine Addition to Lidocaine in Rhinoplasty

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01827020
Recruitment Status : Completed
First Posted : April 9, 2013

Brief Summary:
The purpose of this study is to determine whether subanesthetic ketamine addition to lidocaine decreases postoperative pain scores in infiltration anesthesia during rhinoplasty.

Condition or disease Intervention/treatment Phase
Nose Deformities, Acquired Drug: Lidocaine 2 % Drug: Ketamine plus Lidocaine Drug: Saline Phase 4

Detailed Description:
In rhinoplasty operations local infiltration anesthesia uses for surgery insight and patient comfort. The investigators designed this study to prolonged the time of infiltration block and preventive analgesia. So, before operation, study drugs will infiltrate to the submucosa of intranasal cavity. Then, surgeon and patient satisfaction, postoperative analgesic demand, postoperative pain scores and side effects will determine.

Arm Intervention/treatment
Active Comparator: Group L (number of participants=30)
After standard anesthesia induction and before surgery, patients will receive submucosal infiltration of 12 mL lidocaine 2%, 1mg/kg into nasal cavity.
Drug: Lidocaine 2 %
12 mL lidocaine 2% 1mg/kg
Other Name: preincisional infiltration of lidocaine

Active Comparator: Group K (number of participants=30)
After standard anesthesia induction and before surgery, patients will receive submucosal infiltration of 12 mL ketamine 0.5 mg/kg plus lidocaine 2% 1 mg/kg of the intranasal cavity.
Drug: Ketamine plus Lidocaine
ketamine 0.5 mg/kg + Lidocaine 2% 1 mg/kg in total volume of 12 mL
Other Name: preincisional infiltration of ketamine plus lidocaine

Placebo Comparator: Group S (number of participants=30)
After standard anesthesia induction and before surgery, patients will receive submucosal infiltration of saline 12 mL into intranasal cavity.
Drug: Saline
12 mL saline (0.9% isotonic solution)
Other Name: preincisional infiltration of saline

Primary Outcome Measures :
  1. Postoperative pain scores on the Visual Analogue Scale [ Time Frame: 24 hours ]
    Pain scores will examine with Visual analogue scale (VAS, 0-100) in the first 24 hours of postoperative period. The examination will repeated in different time period(5.min, 15.min, 30.min, 1 h, 2h,4.h, 6.h, 8.h, 16.h, 24.h). Patients that have VAS>40 will receive 1mg/kg tramadol.

Secondary Outcome Measures :
  1. Patient satisfaction [ Time Frame: 24 hour ]
    At the end of postoperative 24 h, the patient satisfaction will examine by a score as (1 poor, 2 middle, 3 good, 4 perfect)

  2. Analgesic demand [ Time Frame: 24 hour ]
    At the first day of postoperative period, analgesic requirement will record. When Visual analogue scale > 40, intravenous 1 mg/kg tramadol bolus will give.

Other Outcome Measures:
  1. Number of participants with adverse effects as a measure of safety and tolerability [ Time Frame: 24 hour ]
    Sedation, nausea and vomiting, dizziness, and hallucination will examine as an adverse effect in all patients.
