This prospective randomized study aims to evaluate the effectiveness of intravenous lidocaine injection on the relief of pain in patients undergoing thyroidectomy. A total 56 patients will be randomized into one of two groups(group C or group I) based on Excel number generation. Patients in group C will receive normal saline intravenous injection, and patients in group I will receive an intravenous bolus injection of 1.5mg/kg lidocaine followed by a continuous lidocaine infusion of 2mg/kg/hr. Visual analogue scale pain scores, fentanyl consumption, the frequency at which patients pushed the button(FPB) of a patient-controlled analgesia system, and presence or absence of nausea and vomiting will be recorded at 2,4,8,12,24,48 hours postoperatively.

RECRUITINGPostoperative pain measured using Visual analogue scale at postoperative 2hour
Patients will be assessed for pain using a visual analogue pain scale(VAS). It is usually a horizontal line, 100mm in length, anchored by word descriptors at each end; left side end which represents 0 is 'No pain', right side end with 100 is 'Very severe pain'. The patient marks ont the line the that they feel represents their perception of their current state. The VAS score is determined by measuring in millimeters from the left hand end of the line to the point that the patient marks. To check the severity of pain VAS will be measured at post op 2hour.
Time frame: post op 2hour

Opioid consumption 2hour
The patients will be taught to push the button of the PCA system, which delivered a bolus of drug, each time pain occured. In the case of persistent pain greater than a visual analogue scale(VAS) pain score of 30mm, and additional 50㎍ of fentanyl will be injected intra-venously by nursing staff until the pain was relieved to a level less than a VAS pain score of 30mm. And sum of delivery from PCA system and and additional opioid fom immediately after operation to post op 2hour will be measured.
