Brief Summary:
Breast augmentation surgery can cause important postoperative pain, especially when bilateral subpectoral implants are used. The investigators hypothesized that a technique of regional analgesia, the pectoral nerve block type I (or "PECS I block") would reduce pain within the first twenty-four hours and, in turn, morphine consumption and associated side effects. This is a randomized, controlled, double-blind study which compares intra and postoperative analgesia with or without PECS I block in breast surgery.

Drug: Placebo
20 mL saline 0.9%
Other Name: saline

Experimental: PECS group
PECS block performed with Ropivacaine 3.75mg/mL
Drug: Ropivacaine (PECS bloc)

Ropivacaine 3.75mg/mL

Other Name: ropivacaine

Primary Outcome Measures :
  1. Morphine consumption [ Time Frame: During the first 24 postoperative hours ]
    Morphine consumption by use of patient control analgesia within the first twenty-four hours after surgery.

Secondary Outcome Measures :
  1. First administration of morphine [ Time Frame: During the first 24 postoperative hours ]
    Time elapsed between tracheal extubation and first administration of morphine

  2. Post-operative nausea and/or vomiting [ Time Frame: During the first 24 postoperative hours ]
    Number of nausea and/or vomiting episodes in the twenty-four hours after surgery

  3. Intra-operative opioids consumption [ Time Frame: During procedure execution ]
    Sufentanil consumption during anesthesia

  4. Post-operative anti-emetic consumption [ Time Frame: During the first 24 postoperative hours ]
    Consumption of anti-emetic drugs after surgery

  5. Post-operative pain [ Time Frame: During the first 24 postoperative hours ]
    Evaluation of post-operative pain with a digital scale from 0 to 10 in the first twenty four hours after surgery

  6. 4-point sedation scale [ Time Frame: During the first two postoperative hours ]

    using WHO Sedation scale

    - 0 = awake and alert /- 1 = quietly awake / - 2 = asleep but easily roused / - 3 = deep sleep

  7. Aldrete score [ Time Frame: During the first two postoperative hours ]
    Aldrete Score is a medical scoring system for the measurement of recovery after anesthesia (post anesthesia) which includes activity, respiration, consciousness, blood circulation and color.

  8. Time physiological function recovery [ Time Frame: During the first six postoperative hours after tracheal extubation ]
    Ability to drink, to eat, to urinate, to walk
