Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patients in the intervention group will receive an intraoperative intravenous infusion of 2% lignocaine (20mg/ml solution). The perioperative lignocaine protocol will be as follows: Immediately prior to surgical incision, an intravenous loading dose (1.5mg/kg) of 2% lignocaine will be administered over 10 minutes followed by an continuous infusion of intravenous 2% lignocaine at 1.5 mg/kg/hr for the duration of the operation. The duration of this operation at our institution is approximately 2 - 3 hours. At surgical closure, the intravenous infusion will be stopped and a subcutaneous infusion of 2% lignocaine will be commenced at 1.5mg/kg/hr for 24 hours postoperatively. Additional multimodal analgesia including morphine patient controlled analgesia (PCA) will be available for rescue analgesia according to routine hospital protocols for postoperative analgesia. The morphine patient controlled analgesia device will contain morphine (1mg/ml), and will be set with a 5 minute lockout and will continue for 24 hours. Multimodal analgesia will consists of paracetamol 1g orally/intravenously 6 hourly and ketorolac orally/intravenously 30mg 6 hourly (if no contraindications) for 24 hours.

Treatment: Drugs
Comparator / control treatment
Patients in the control group will receive an intraoperative intravenous infusion of placebo (normal saline), followed by a subcutaneous infusion of placebo (normal saline) for 24 hours postoperatively, in additional to routine multimodal analgesia including morphine patient controlled analgesia.
Control group
Placebo

to normal
3. Mild pain adequately controlled with oral analgesics
4. No postopeartive nausea or vomiting

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients will be informed about the study and consented at the preanaesthesia admission clinic 1-2 weeks prior to surgery.

On the day of surgery, an independent anaesthetist or research nurse who is not a study investigator will open a sealed opaque randomisation envelope. The independent anaesthetist will prepare either 2% lignocaine or 0.9% saline in coded two 50 mls syringes for intraoperative use and a 2% lignocaine 200 mL flask for the postoperative infusion. The syringes and flask will be labeled 2% Trial Drug (ie each mL = 20mg) with coloured printed labels.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation by using a randomization table created by a computer software (i.e., computerised sequence generation) will be preformed. For each patient, an opaque envelope containing the group assignment will be prepared, sealed and sequentially numbered. On the morning of surgery the anaesthetist will open the envelope and randomised the patients into one of the two groups described above.
