About this study
Official title: Intravenous Lidocaine for Effective Pain Relief After Tonsillectomy: a Prospective, Randomized, Double-blind, Placebo-controlled Study
This prospective randomized study aims to evaluate the effectiveness of intravenous lidocaine injection on the relief of pain in patients undergoing tonsillectomy.
A total of 62 patients will be randomized into one of two groups (group C or group I) based on Excel number generation.
Read more
Patients in group C will receive received normal saline intravenous injection, and patients in group I will receive an intravenous bolus injection of 1.5 mg/kg lidocaine followed by a continuous lidocaine infusion of 2 mg/kg/hr.
Visual analogue scale pain scores, fentanyl consumption and the frequency at which patients pushed the button (FPB) of a patient-controlled analgesia system will be recorded at 4, 12, 24, 48 hours postoperatively.

| Study group | Role | What they receive |
|---|---|---|
| Intravenous lidocaine injection group | Active comparator | Patients in Group I (intravenous lidocaine injection group) received an intravenous bolus injection of 1.5 mg/kg lidocaine followed by a continuous lidocaine infusion of 2 mg/kg/hr. Receives: Drug: Intravenous lidocaine injection |

What is being measured
The primary outcome is the main question the study is designed to answer.
Visual analogue scale 4hour
Patients will be assessed for pain using a visual analogue pain scale (VAS). It is usually a horizontal line, 100 mm 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 on the line the point 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 4hour.
Measured: post op 4hour

Opioid consumption 4hour
The patients will be taught to push the button of the PCA system, which delivered a bolus of drug, each time pain occurred. In the case of persistent pain greater than a visual analogue scale (VAS) pain score of 30 mm, an additional 50 μg 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 30 mm. And sum of delivery from PCA system and additional opioid fom immediately after operation to post op 4hour will be measured.

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 9 Feb 2011. 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?
Visual analogue scale 4hour (time frame: post op 4hour). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 9 Feb 2011.
