      Abstract

      Objective

      The aims of this study were to assess the effect of intraoperative cryoablation on postoperative patient reported pain, opioid use, and clinical outcomes in lung transplantation.

      Methods

      We performed a single-center retrospective cohort study of adult lung transplant recipients from August 2017 to September 2018. We compared outcomes of patients who received intraoperative cryoablation of the intercostal nerves to those who did not. Primary outcomes were postoperative patient reported pain scores and opioid use. Secondary outcomes included postoperative sedation and agitation levels and perioperative outcomes. Data were abstracted from patients’ electronic health record.

      Results

      Of the 102 patients transplanted, 45 received intraoperative cryoablation (intervention group) and 57 received the standard of care which did not include intercostal or serratus blocks or immediate postoperative epidural placement (control group). The intervention group had significantly lower median and maximum postoperative pain scores at days 3 and 7 and significantly lower oral opioid use at days 3, 7, and 14 compared to the control group. Chronic opioid use at 3- and 6-months post-transplant was lower in the intervention. Differences in perioperative outcomes including length of mechanical ventilation, sedation and agitation levels, and hospital stay were not clinically meaningful. Survival at 30-days and 1-year was superior in the intervention compared to the control group.

      Conclusions

      Findings suggest that use of intraoperative cryoablation is an effective approach for treating pain and reducing opioid use in lung transplant patients, but randomized study across multiple institutions is needed to confirm these findings.
