Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
In the continous group under ultrasound guidance TAP block performed and catheter inserted,thru the catheter the anaesthetist boluses ropivacaine 0.5% 20ml on each side, followed by ropivacaine 0.2% infusion @ 8ml/hr each side in recovery room till 48hrs. whereas in Intermittent group with same technique and same bolus dose as other gp but subsequent bolus of 0.2% ropivacaine 20ml each side delivered by pain service team at 8hours intervel till 48hrs.
Patients in both groups will be provided with Paracetamol 1 gram 4 times a day (orally or IV) and a Fentanyl PCA device (bolus 10 to 40 mcg; lockout time 5 min; no back-ground infusion) as part of a multimodal analgesic approach

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Transversus abdominis plane (TAP) block with catheter is inserted intra operatively in all cases but the method of local anaesthetic delivery in the post op period is either intermittent bolus or continous infusion group.
The allocation done by simple randomisation table created by computer software(computerised sequence generation). This allocation was concealed by sealed opaque envelope with numbered and group what alloted to .

Efficacy
Statistical methods / analysis
The data will be analysed using the following methods: differences between the
continuous variables by the “t”-test; categorical variables by Fisher's exact test. The pain scores between groups (Continuous vs Intermittent TAP) will be analysed by rank non-parametric methods (Man Whitney U test).

Summary
Brief summary
This prospective study 0f 20 patients.In both the groups Bilateral TAP catheters will be placed using an ultrasound guided approach post-operatively with the bolus dose of 20 ml of 0.5% Ropivacaine bilaterally. In post anaesthetic care unit (PACU) an infusion of Ropicavaine 0.2% will be administered @ 8ml/hr for 2 days in the Continuous group. Whereas in Intermittent group only bolus doses 20ml 0.2% ropivacaine will be administered by the Acute pain service personnell every 8 hrly for 48 hrs.

Patients in both groups will be provided with Paracetamol 1 gram 4 times a day (orally or IV) and a Fentanyl PCA device (bolus 10 to 40 mcg; lockout time 5 min; no back-ground infusion) as part of a multimodal analgesic approach.

The following parameters will be registered:
Numerical Rating Scores for Pain (NRS-P; 0-10) at rest and on coughing in PACU at 0 and I hour and in the postoperative ward at 24 hrs, 48 hrs.
Fentanyl use in PACU and postoperative ward on day 1 & day 2.
Procedure related: material costs and other issues will be noted.
Any rescue medication used.
A 4 point ‘Likert’-scale will be used on day 2 and during a follow-up telephone call at one month to assess patient satisfaction with the analgesic technique used.
discharge time and cost analysis will be assessed.

All results will be recorded on a data collection sheet in a prospective fashion and subsequently entered in a protected database
