Clinical Trial Summary

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.

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	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.	post op 4hour	No
Secondary	visual analogue scale 12 hour	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 12 hour.	Post op 12 hour	No
Secondary	visual analogue scale 24hour	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 12 hour.	Post op 12 hour	No
Secondary	Visual analogue scale 48hour	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 48 hour.	Post Op 48hour	No
Secondary	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.	Post Op 4hour	No
Secondary	Opioid consumption 24hour	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 from 12 hour to post op 24 hour will be measured.	Post op 24 hour	No
Secondary	Opioid consumption 12 hour	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 from post op 4hour to post op 12 hour will be measured.	Post Op 12 hour	No
