The hypothesis is that epidural pethidine is an effective form of pain relief following lumbar spinal surgery, resulting in significantly lower usage of concomitantly administered (intravenous) patient-controlled analgesia (PCA) pethidine.

Secondary Outcome Measures:
  • Patient data:
  • Age
  • Gender
  • Body mass index
  • Current medications
  • Preoperative opioid analgesic use (none, low, high - high dose being > 300 mg codeine or dextropropoxyphene daily or oral morphine or parenteral opioid use)
  • Compensable status (HNC, TAC, WCV or PMI/SUR) 22
  • Surgical data:
  • Anatomical extent of surgery (number of spinal levels)
  • Highest anatomical surgical level
  • Experience level of primary surgeon (trainee or consultant)
  • Anatomical level of epidural tip (identified from postoperative X-Ray when taken as routine care only)
  • Dural tear at the time of surgery (yes/no)
  • Spinal instrumentation (yes/no)
  • Other end-points (all at 1, 4, 24 and 48 hours unless stated):
  • Cumulative pethidine dose
  • Cumulative morphine dose
  • VAS scores for pain at rest and during movement
  • Sedation score (1 - 4) 16
  • VAS scores for nausea, pruritis
  • Other adverse events: agitation, tremor, hallucinations, seizure
  • Patient satisfaction scale for pain control during study (48 hours) [ Time Frame: 48 hours ]
  • (very dissatisfied, dissatisfied, neutral, satisfied, very satisfied) 17
  • Plasma pethidine and norpethidine levels (24 hours) [ Time Frame: 24 hours ]
  • Physiotherapy assessment of ability to deep breathe & cough (unable, poor, adequate, good)
  • Length of inpatient stay
