Study information
Scientific title
Comparison of the effect of transversus abdominis plane block or conventional analgesia on pain scores, patient satisfaction and incidence of chronic pelvic pain after total abdominal hysterectomy: a randomised double-blind controlled trial
Acronym
Study hypothesis
Is there a significant difference in post-operative pain scores in patients undergoing total abdominal hysterectomy who have received bilateral transversus abdominis plane blockade compared to a standard post-operative analgesia regime?
Ethics approval
Health and Social Care Research Ethics Committee (HSC REC 2) (Northern Ireland) approved on the 12th August 2008 (ref: 08/NIR02/75)

Condition
Total abdominal hysterectomy
Intervention
Patients will be randomised to receive either a bilateral transversus abdominus plane block (TAPB) using 1 mg/kg 0.375% levobupivacaine up to a maximum of 20 ml bilaterally in addition to a standard analgesia regime of patient contolled morphine (1 mg/ml maximum 12 ml/hr) and intravenous paracetamol (1 g 6-hourly). Patients randomised to receive a standard analgesia regime only will have 1 ml of 0.375% levobupivacaine injected into the area where the TAPB would normally be performed in order to maintain the double blind nature of the trial.
Added 09/08/2011: Trial closed early due to low recruitment secondary to change in surgical technique - 30 patients recruited in total.

Primary outcome measure
The reduction in visual analogue scores (VAS) in the post-operative period for patients undergoing total abdominal hysterectomy.
Secondary outcome measures
1. Usage of morphine sulphate in the post-operative period
2. Incidence of nausea and/or vomiting within the first 48 hours after surgery
3. Measurement of oxygen saturations without supplemental oxygen in both groups in the post-operative period
4. Incidence of complications associated with the analgesia techniques in both groups
5. Patient satisfaction with analgesia technique
6. Incidence of chronic pelvic pain at 3 months
