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.

What is being measured
The primary outcome is the main question the study is designed to answer.
Postoperative 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.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Intravenous lidocaine injection and Intravenous normal saline injection in people with Postoperative Pain, run by Chung-Ang University Hospital at 1 site in South Korea.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 19 Mar 2014. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Hyun Kang, Ph.D (82-2-6299-2571, roman00@naver.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Postoperative pain measured using Visual analogue scale at postoperative 2hour (time frame: post op 2hour). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01608360, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Mar 2014.
