Information provided by (Responsible Party):
McMaster University ( Hamilton Health Sciences Corporation )
  Purpose
The purpose of this study is to examine 4 different epidural dosing regimes of local anaesthetic solution in a series of 3 epidural injections over a period of 12 months to determine the optimum dose of anaesthetic solution for pain relief and to determine the nature of any adverse events by measuring anxiety and depression, functionality and any side effects of the medication.

Condition Intervention
Chronic Low Back Pain Drug: Bupivacaine Drug: Depo-Medrol

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Single Group Assignment
Masking: Double (Participant, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Effects of Volume and Dose of Local Anaesthetic Solution in Epidural Steroidal Injections for Patients With Chronic Lower Back Pain

Primary Outcome Measures:
  • The volume and dose of local anesthetic injected epidurally, in combination with the steroid, will be measured against the duration and degree of pain relief. [ Time Frame: Pain scores will be measured at 6 time intervals throughout the study period, prior to 1st injection, 30 minutes post 1st injection, prior to 2nd injection and 3rd injections and at 3 and 6 month post the three month injection. ]

Secondary Outcome Measures:
  • Secondary outcomes will be scores on the Oswestry low back pain disability scale and the Hospital anxiety and depression scale correlated with treatment outcomes and adverse events. [ Time Frame: Oswestry scores and HADS scores will be calculated at 5 time periods throughout the study period, prior to 1st, 2nd, and 3rd injections and at 3 and 6 month post the three month injection. ]
