Unilateral thoracic paravertebral blocks (TPVBs) have demonstrated reliable intraoperative analgesia, low postoperative pain scores, and an opioid-sparing effect in breast cancer surgery. However, secondary to the perceived risk of complications, bilateral TPVB been less well accepted are frequently used. The purpose this study was evaluate feasibility using TPVBs outpatient surgery for patients undergoing mastectomy with immediate implant-based reconstruction. Electronic medical records were retrospectively reviewed receiving reconstruction performed by a single surgeon from September 2012 2015. Records incidence time discharge, unplanned admission or readmission. Clopper-Pearson method binomial distribution used calculate confidence intervals proportions. Forty-five received TPVBs.
