Breast augmentation under local anesthesia with intercostal blocks and light sedation

INTRODUCTION: This study of breast augmentations performed under local anesthesia with intercostal blocks and light sedation describes the outcomes and evaluates benefits and complications. METHOD: From December 2005 until August 2019, 335 women consecutively underwent bilateral breast augmentation procedures. The anesthetic protocol consisted of an initial intravenous bolus of 1 mg midazolam and 0.25 mg alfentanil preoperatively. In 2017, this was changed to 2-4 mg midazolam intramuscularly, 1 mg midazolam intravenously, and 2.5 µg sufentanil intravenously. Intercostal blocks were injected at the midaxillary line into the intercostal spaces two to seven. The operating field was infiltrated with tumescent local anesthesia. Retrospective data extraction from patients' medical charts was done, registering demographics, dosage of anesthesia, surgical characteristics, complications, and reoperation rates. RESULTS: < 0.0001) decreased need for supplementary medication with no increased risk of complications. CONCLUSION: Breast augmentations in local anesthesia with intercostal blocks and light sedation can be performed safely and can serve as an alternative to procedures in general anesthesia.
