Efficacy of a 96hr duration local anaesthesia (l-bupivacaine) infusion using PainBuster device at the incision site compared with saline controls for post-operative pain management against a background of narcotic analgesia, following open or laparoscopic abdominal surgery.

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The aim is to test whether continuous local anaesthetic infusion (0.5% l-bupivacaine at 5ml/h for 0-48hr and 2ml/h for 48-96h post-op) using a commercial infiltration device can minimise, or eliminate, the need for narcotic analgesia following abdominal open or laparoscopic surgery. The potential benefits to the patient include earlier mobilisation, minimisation or averting the side-effects from narcotics (a particular issue in elderly patients following abdominal surgery), and shorter length-of-stay.

Control group
Placebo

Outcomes
Primary outcome [1] 3221 0
Pain management measured by (a) reduction in demands and usage of narcotic available using patient-controlled analgesic (PCA) device, and (b) visual analogue pain scores in patients on local anaesthetic infusion compared with saline/placebo controls
Timepoint [1] 3221 0
pain scores and PCA usage recorded 12 hourly for 96 hours post-op
Secondary outcome [1] 5375 0
patient satisfaction, mobilisation, return normal bowel function, would infection, length of hospital stay, adverse effects from local anaesthetic, unbound l-bupivacaine concentrations throughout infusion period
Timepoint [1] 5375 0
wound sterility, drug conc, pain scores determined 12hrly
Satisfaction at discharge and followup
