<p><strong>Introduction</strong></p>

<p>Current studies show cryoablation decreases opioid requirements and lengths of stay (LOS) in patients undergoing the Nuss procedure for pectus excavatum. This study evaluated the relationship between cryoablation and clinical outcomes for the Nuss procedure.</p>

<p><strong>Methods</strong></p>

<p>A retrospective single-center chart review was performed on patients undergoing the Nuss procedure with intercostal cryoablation from December 2017-August 2021. Demographics, hospital course, and postoperative complications were abstracted. To evaluate the evolution of outcomes over time, the earliest quarter (Q1) of cryoablation patients was compared to the last quarter (Q4).</p>

<p><strong>Results</strong></p>

<p>Over 45 months, 350 Nuss procedures with cryoablation were performed. The mean age at operation was 15.7 ± 2.3 years with an average Haller Index of 5.4 ± 4.2. The mean operative time was 136 ± 40.5 minutes. On average, patients used 2.8 ± 2.5 OME/kg of opioid in hospital with a LOS of 2.7 ± 1.1 days. The Q4 patients were discharged 1.3 days earlier (p<0.05) than Q1 patients, with 80% of Q4 discharged by postoperative day #2 vs. 23% in Q1 (p<0.05). Q4 patients received 74% (p<0.05) less opioid in hospital and 21% (p<0.05) less on discharge. Within 90 days postoperatively, complication rates (chest tube placement, wound infection, readmission, neuropathic pain) were similar. Only two patients (0.6%) required reoperation for bar migration/slippage.</p>

<p><strong>Conclusion</strong></p>

<p>With increased experience, cryoablation for the Nuss procedure decreased opioid use by 74% and was associated with 80% of patients achieving early discharge. Major complication rates were not increased. Cryoablation can be successfully implemented as an effective method of postoperative analgesia.</p>

## Transcript
Do you use cryo for the NAS procedure? Hi, I'm Cecilia Jigena from Cincinnati Children's Hospital, and I think this is an article that you should know about. This is a retrospective single institution study done in Phoenix from 2017 to 2021. And their aim was to compare patients that underwent NAS procedure with cryoanalgesia in the 1st quarter of their experience with the 4th quarter of their experience, and what did they find? They had 350 patients that underwent NAS procedure with cryo analgesia. And what they found is that patients in the last quarter were discharged 1.3 days earlier than patients in the first quarter and also requires 74% less opioids. So it seems that experience really plays a role talking about cryoathesia. Let us know what you think and stay tuned for more articles that you should know about.
