Objective: To determine if the irrigation of the breast cavity with local anesthetics in patients who undergo breast augmentation surgery reduces rescue analgesic requirements and postoperatory pain intensity level, measured with the analogue visual scale. Methods: Placebo controlled non randomized clinicál triál. In the intervention group the breast cavity was irrigated with 1% lidocaine with epinephrine (7 mg/kg), 0,5% bupivacaine (3 mg/kg) and normal satine solution. In the second group the breast cavity was irrigated with satine solution. Anesthetic and transition analgesia techniques were standardized. Type (morphine, hydromorphone and meperidine) and total required dose of opioid rescue analgesic medication in the Post Anesthetic Core Unit were also registered. Postoperative pain intensity level was also registered at the moment of consciousness recovery, at thirty minutes, at the first hour, at two, five and twenty four hours of postoperative period. Results: There was a difference in the number of patients requiring opioid rescue analgesia with morphine at the Post Anesthetic Care Unit (p<0.01), 10% in the intervention group versus 50% in the control group. Likewise, there was difference in pain intensity level (p<0.01). Conclusions: Local anesthetic irrigation in patients who underwent breast augmentation surgery reduces opioid rescue analgesia requirements and postoperative pain intensity level.
