Summary

The purpose of this randomized controlled study is to compare the postoperative analgesic effect of a continuous wound infusion of local anesthetics and a sole transverse abdominal plan (TAP) regional block in the surgery of Abdominoplasty Combined With Flank Liposuction. Local anesthetics products used are ropivacaine combined with clonidine. Similar amount of local anesthetics and clonidine are used.

Detailed description

In a first group, patients receive, after induction of anaesthesia and before surgery, a TAP block (transverse abdominal plan block) with 3mg/kg Ropivacaine 0.5% (maximum 200 mg) and 150 microg Clonidine. In a second group, before skin closure, a multiholes catheter was inserted beyond the skin. 20 mg Ropivacaine 0.2% added with 150 microg Clonidine was injected as bolus dose through this catheter followed by a continuous infusion of Ropivacaine 0.2% 10ml per hour during the following 9 hours (total dose of 200 mgr).

Conditions

• Surgery of Abdominoplasty With Flank Liposuction

Interventions

Type	Name	Description
PROCEDURE	Transverse abdominal plan block	Transverse abdominal plan block was performed after induction of anaesthesia and before surgery. 3 mg/kg of Ropivacaine 5mg/ml (maximum 200 mg) plus 150 microg of Clonidine were injected at the good place. The was realised with the aid of ultrasound
PROCEDURE	Continuous wound infusion	In this group, a multihole catheter was surgically inserted vertically before skin closure. The catheter was primed with Ropivacaine 2 mg/ml 10 ml plus clonidine 150 microg before the end of anaesthesia. Continuous wound infusion was started at a rate of 10 ml per hour of Ropivacaine 2 mg/ml during the first 9 hours after the surgery.
