BackgroundSeveral approaches to minimize postoperative pain, nausea, and enhance recovery are available for patients undergoing mastectomy with immediate tissue expander (TE) reconstruction. We compared the effectiveness of intraoperative local infiltration of liposomal bupivacaine (LB) to preoperative paravertebral block (PVB).MethodsWe retrospectively reviewed patients who underwent mastectomy with immediate TE reconstruction between May 2012 and October 2014 and compared patients with preoperative ultrasound-guided PVB to those with intraoperative LB infiltration.ResultsFifty-three patients (54.6 %) received LB and 44 received PVB. LB was associated with less opioid use in the recovery room (p < 0.001), fewer patients requiring antiemetics (p = 0.03), and lower day of surgery pain scores (p = 0.008). LB also was associated with longer time to first opioid use (p = 0.04). On multivariable analysis controlling for expander placement location, year of surgery, and axillary lymph node dissection (ALND), the only variable that remained statistically significant was lower opioid use in the recovery room for patients with LB (p = 0.03) and day of surgery pain scores approached significance (p = 0.05). There was no difference in the proportion of patients discharged within 36 h of surgery between the groups. Focusing on first cases of the day (where PVBs are performed in the OR) showed average time to skin incision was 15 min shorter in the LB group (p = 0.004).ConclusionsLocal infiltration of LB in patients undergoing mastectomy with immediate TE reconstruction decreases narcotic requirements in the recovery room, shortens preoperative anesthesiology time, and provides similar, if not better, perioperative pain control compared with PVB.
