A Preemptive Epidural Ropivacaine for Postoperative Pain Relief in Degenerative Lumbar Spine Surgery

Phase 4
Conditions
Postoperative Pain
Interventions
Drug: Placebo (one of medication)
Registration Number
NCT01117610
Lead Sponsor
Chung-Ang University Hosptial, Chung-Ang University College of Medicine
Brief Summary

This prospective randomized study aims to evaluate the effectiveness of epidural injection of ropivacaine on the relief of pain in patients undergoing laminectomy.

Total 60 patients will be randomized into one of two groups (groupC or groupI) based on Excel number generation.

Patients in group C will receive no medication intraoperatively, and patients in group I will receive epidural injection of 0.1% ropivacaine 10ml before skin incision.

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 hour postoperatively.

Detailed Description

Patients in group I will receive 0.1% ropivacaine 10 ml before skin incision under guide of C-arm.

Primary Outcome Measures
NameTimeMethod
Visual analogue scale 4hourpost 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

visual analogue scale 24hourPost Op 24 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 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.

Visual analogue scale 48hourPost 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 4hourPost 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.

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.
