Brief Summary:
Breast augmentation is among the most popular surgical procedures performed in the world with approximately 1,773,584 performed in 2013. This surgical intervention generates important pains during postsurgical recovery. A multimodal analgesia, based on the recommendations is proposed to the patients .The pectoral nerve block is an innovative technique of locoregional anesthesia that has already been successfully used in breast surgery. Its realization is fast, simple, and it would be superior compared with a paravertebral block within the framework of mastectomy. The interest of this technique has never been assessed in esthetic breast surgery. The aim of this study is to evaluate the analgesic efficacy of the association of " Pecs blocks 1 and 2 " on pain intensity after breast augmentation surgery.

Condition or disease Intervention/treatment Phase
Ambulatory Plastic Surgery Esthetic Prosthetic Breast Expansion Drug: Ropivacaine after dilution with sodium chloride 0.9% Phase 3

Detailed Description:

The investigators hypothesized that the "Pecs blocks 1 and 2" will provide a decrease of the maximal pain of the first 6 post-operative hours after prosthetic breast expansion. The pain will be assessed according to a numerical scale. This prospective, randomized, double blind study will include 92 patients successively during two years, randomized into two arms : Pecs group and Control group, which will respectively have the block, and no block. The rest of the anesthesic and surgical care will be identical.

An intervention team (which will be different from the anesthesic team), will be alone with the patient for 15 minutes, and will realize or not the Pecs blocks according to the previous randomisation so that all caregivers taking in charge the patients as well as research observers will be blinded.

Arm Intervention/treatment
No Intervention: Control group (1)
The PECS Blocks are not (1) performed.
Experimental: PECS group (2)
The PECS Blocks are performed (2): A single injection of Ropivacaine after dilution with sodium chloride 0.9% per fascial plane and per side.
Drug: Ropivacaine after dilution with sodium chloride 0.9%

After the anesthesic induction, the interventional team composed by at least a senior anaesthesiologist and a nurse anesthestic, will survey the patient and perform the Pecs blocks, whereas the anesthetic team is outside the room.

Realization of Pecs blocks 1 and 2 : the patient is in supine position with placing the upper limb in abduction position, a 100 mm needle is inserted under ultrasound using a linear US probe of high frequency after sheathing.

In the other group, sterilization, sheating and US are performed but the needle is not inserted.

Primary Outcome Measures :
  1. Maximal value of pain intensity according to the numerical scale within the six first hours [ Time Frame: up to First six postoperative hours ]

Secondary Outcome Measures :
  1. Maximal value of the pain at day 1 and until day 5 [ Time Frame: Five days ]
    Value of pain according to a Numeric scale , recorded at day 1 in the hospital, and until day five by phone interview.

  2. Morphinics side effects such as nausea / vomiting, constipation, pruritus; analgesic consumption, surgical complication, satisfaction questionaire [ Time Frame: Five days ]
    Any of side effect
