Next day discharge after the Nuss procedure using intercostal nerve cryoablation, intercostal nerve blocks, and a...

The Nuss procedure for pectus excavatum has historically been associated with significant postoperative pain, which has been the major factor contributing to hospital length of stay (LOS).

A single-institution, prospective study of 40 consecutive patients undergoing Nuss bar placement for pectus excavatum between November 2019 and January 2021 was conducted to assess the effectiveness of a multimodality pain management protocol. All patients received T3-T8 intercostal nerve cryoablation (INC), T3-T8 bupivacaine intercostal nerve blocks, Exparel at the skin incisions, and management with a perioperative analgesia regimen that minimized narcotic usage. The primary outcome was LOS. Secondary outcomes included opioid use, pain scores, and time to sensory recovery.

37/40 patients (92.5%) were discharged home on postoperative day (POD) 1, and 3/40 (7.5%) were discharged on POD 2 (mean LOS = 1.1 days). The median average postoperative pain score was 2/10. After eliminating IVPCA from our protocol, total oral morphine equivalent (OME) decreased by 73% (55.5 mg to 15 mg) with no change in pain scores or discharge timing.

INC combined with bupivacaine intercostal nerve blocks and a pre- and post-hospital analgesia protocol facilitated discharge one day after the Nuss procedure, achieved excellent pain control, and eliminated the need for intravenous opioids.
