The Effect of Intravenous Lidocaine on Pain After Tonsillectomy
- Conditions
- Postoperative Pain
- Interventions
- Drug: Intravenous normal saline injection
- Registration Number
- NCT01291979
- Lead Sponsor
- Chung-Ang University Hosptial, Chung-Ang University College of Medicine
- Brief 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.

Group Intervention Description Intravenous lidocaine injection group Intravenous lidocaine injection 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. Placebo control group Intravenous normal saline injection Patients in Group C (placebo control group) received normal saline intravenous injection
- Primary Outcome Measures
Name Time Method Visual analogue scale 4hour post op 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.
- Secondary Outcome Measures
Name Time Method visual analogue scale 12 hour Post op 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.visual analogue scale 24hour Post op 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.Visual analogue scale 48hour Post Op 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.Opioid consumption 4hour Post Op 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.
Opioid consumption 24hour Post op 24 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 12 hour to post op 24 hour will be measured.
Opioid consumption 12 hour Post Op 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.
Opioid consumption 48hour Post Op 48 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 24 hour to post op 48 hour will be measured
FPB 4 hour Post Op 4 hour The patients will be taught to push the button of the PCA system, which delivered a bolus of drug, each time pain occurred. And total frequency of patient to push the button of the PCA machine (FPB) fom immediately after operation to post op 4 hour will be measured.
FPB 12 hour post op 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. And frequency of patient to push the button of the PCA machine (FPB) from post op 4 hour to post op 12 hour will be measured.
FPB 24 hour Post Op 24 hour The patients will be taught to push the button of the PCA system, which delivered a bolus of drug, each time pain occurred. And frequency of patient to push the button of the PCA machine (FPB) fom post op 12 hour to post op 24 hour will be measured.
FPB 48 hour Post Op 48 hour The patients will be taught to push the button of the PCA system, which delivered a bolus of drug, each time pain occurred. And frequency of patient to push the button of the PCA machine (FPB) fom post op 24 hour to post op 48 hour will be measured.
