Study information

Scientific title

A randomised, triple-blind, placebo controlled trial evaluating the analgesic efficacy of continuous paravertebral block (PVB) following hemipelvectomy for pelvic tumours.


Study hypothesis

Does a PVB block following hemipelvectomy provide better analgesia than the current treatment protocol?

Ethics approval

South Birmingham Research Ethics Committee - submitted as of 20/02/2015

Study design

A prospective, randomised, triple-blind, placebo-controlled trial comparing the effects of continuous LA infusion with a placebo infusion of 0.9% sodium chloride following hemipelvectomy. This is a single centre study at the Royal Orthopedic Hospital, Birmingham.

Secondary study design

Patient information sheet


Patients undergoing hemi-pelvectomy for pelvic tumours


Patients will be randomised to receive one of two possible post-operative catheter infusions for 5 days:
1. Bupivicaine 0.125% infusion at a fixed rate of 10ml/hr.
2. 0.9% Sodium Chloride infusion at a fixed rate of 10ml/hr.
This will be in addition to standard post-operative analgesia which encompasses combined epidural and spinal anaesthetic, and patient controlled analgesia.

Primary outcome measure

1. Pain score – measured by Numeric Rating Scales (NRS) (0-10)
1.1. Worst pain score
1.2. Least pain score
1.3. Frequency of severe pain (NRS 0-100%)
Pain will be measured at 4, 8, 12, 24 hours post-operatively using a validated questionnaire. It will be measured daily between 24 hours - 7 days and then weekly until discharge. A final questionnaire will be administered on the day of discharge.

Secondary outcome measures

1. Interference with activities (measured by NRS 0-10)
1.1. Activities in bed (e.g. turning, sitting up, changing position)
1.2. Breathing deeply/coughing
1.3. Sleep quality
1.4. If out of bed: activities out of bed (e.g. sitting in chair, walking with aids)
2. Side effects of opioid analgesia (measured by NRS 0-10)
2.1. Nausea
2.2. Drowsiness
2.3. Itching
2.4. Dizziness
3. Emotions (measured by NRS 0-10)
3.1. Anxiousness
3.2. Helplessness
4. Satisfaction with analgesia
4.1. Would you have liked more pain relief (Y/N)
4.2. Apart from this study did you receive any information about pain treatment options? (Y/N)
4.3. How satisfied are you with your pain treatment? (measured by NRS 0-10)
4.4. Have you used non-medicinal forms of pain relief?
5. Urinary retention
5.1. Time to urinary catheter removal (days)
5.2. Re-catheterisation within 24 hours of catheter removal (Y/N)
6. Post-operative ileus
6.1. Bowels open? Y/N
6.2. Passed flatus? Y/N
7. Quantity of opioid use for first five days post-operation (mg)
8. Duration of epidural infusion (hours)
9. Duration of intravenous analgesia (hours)
10. Wound infection rates (defined by antibiotics started for wound infection)
11. Time to first ambulation out of bed (days)
12. Length of High Dependency Unit (HDU) Stay (hours)
13. Length of hospital stay (days)
The subjective outcome measures will be assessed in the form of a previously validated questionnaire (please see Appendix). This questionnaire will be used in its entirety at 4 hours post-operation and again on the date of discharge. A minimally modified version will be utilised to investigate temporal changes in pain control between these time points. A Research Assistant (RA) will give the correct questionnaires to the patient who will complete them independently. Only in exceptional cases (e.g. patient unable to read, reading glasses not available, patient too weak to fill it in independently) will the researcher read the questions to the patient. The objective measures will be obtained by review of the patients’ medical notes.
