Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Intervention consists preperitoneal placement of catheter with multiple side-holes to continuously release 0.5%ropivacaine at 4ml/hr for postoperative 72hours. This placement will be conducted by an experienced attending surgeon.

Intervention with 0.5% ropivacaine (local anesthetics) continuous infusion at 4ml/hr
Intervention code [1] 258032 0
Treatment: Drugs
Intervention code [2] 258046 0
Treatment: Devices
Comparator / control treatment
Control : IV PCA regimen includes fentanyl 16 mcg/ml in 100ml saline bag with basal infusion rate of 0.5 ml/hr, bolus of 1ml at 15min lockout interval. Thus maximum dose allowed per hour is 80mcg and basal infusion is continued with bolus injection when patient presses a button. Overall duration of this method is 72 hours postoperatively.

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 are randomly allocated to one of two groups by using computer based randomized number concealed in an envelop before intervention. All patients receive preperitoneal wound catheterization and IV PCA (intravenous patient controlled analgesia ) device, but one group with study drug only in preperitoneal catheter and the other group with study drug only in IV PCA. Allocation is blinded both to patients and investigators.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Consecutive patients receiving laparoscopic colorectal surgery will be enrolled with randomization sequence generation using computerized randomizer.
Masking / blinding
Open (masking not used)
