  Purpose

Abdominoplasty is a major cosmetic surgery with a painful post operative period. Recently more and more anaesthetists are turning to regional analgesia for anterior abdominal wall surgery namely the Transversus Abdominis Plane (TAP) Block with or without ultrasound guidance.

The aim of this study is to evaluate the analgesic effect of TAP block ultrasound guided in post operative period of abdominoplasty.

Primary Outcome Measures:
  • Opioid consumption during 24 hours after the surgery [ Time Frame: 24 hours after surgery ]

Secondary Outcome Measures:
  • Quality of analgesia [ Time Frame: Until 48 hours after surgery ]
    Evaluated by opioid consumption, visual scale assessment of pain by patient, occurrence of specific adverse events (nausea, vomiting, somnolence, pruritus...)

  • Early rehabilitation : hour of first rising, six-minute walk test at 3days and at discharge [ Time Frame: Until discharge, up to 8 days after surgery ]
  • Evaluation of Neuropathic pain, pain thresholds, hyperalgesia area [ Time Frame: 15 days and 3 month after surgery ]
  • Health - related quality of life preoperative and at 3 months post operatively [ Time Frame: Just before and 3 months after surgery ]

Enrollment: 52
Study Start Date: June 2012
Study Completion Date: October 2013
Primary Completion Date: July 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: TAP Block with levobupivacaïne Procedure: TAP Block
An Ultra Sound-guided TAP block is performed after induction of general anesthesia prior to surgical incision. The syringes containing either saline 20 ml (placebo group) or levobupivacaine 20 ml are prepared by the hospital pharmacy under aseptic conditions.
Placebo Comparator: TAP Block with Placebo Procedure: TAP Block
An Ultra Sound-guided TAP block is performed after induction of general anesthesia prior to surgical incision. The syringes containing either saline 20 ml (placebo group) or levobupivacaine 20 ml are prepared by the hospital pharmacy under aseptic conditions.

Detailed Description:
To determine if TAP block have an analgesic effect in post operative period of abdominoplasty this study was made versus placebo: one group of patients will have a TAP block of levobupivacaine, the second group will have a TAP block with placebo before the surgery. Patient follow up includes data collected before surgery (at pré anesthesic visit and just before surgery) and data collected immediately after surgery (at post operative time) and at distance of the surgery (15 days and 3 months after the surgery). The principal aim is to show if TAP block have an analgesic effect in post operative period after abdominoplasty. To answer this question we will compare opioid intake during the two days after the surgery between the two groups.
