Impact of dexmedetomidine in conjunction with a weaning protocol on post‐surgical opioid use in a neonatal intensive care unit.

Study Objective: To describe the impact of protocol‐driven dexmedetomidine (and clonidine) use on opioid exposure in post‐surgical neonates. Design: Retrospective chart review. Setting: A Level III, surgical NICU. Patients: Surgical neonates who received clonidine or dexmedetomidine concomitantly with an opioid for sedation and/or analgesia post‐operatively. Intervention: Implementation of a standardized sedation/analgesia weaning protocol. Measurements and Main Results: There were clinically, although not statistically, significant reductions in opioid wean duration (240 vs. 227 h, p = 0.82), total opioid duration (604 vs. 435 h, p = 0.23), and total opioid exposure (91 vs. 51 mg ME/kg, p = 0.13), and limited impact on NICU outcomes or pain/withdrawal scores with use of the protocol. Increases in use of medications in alignment with the protocol (e.g., scheduled acetaminophen and opioids weaned first) were noted. Conclusions: We have been unable to demonstrate a reduction in opioid exposure with use of alpha‐2 agonists alone; addition of a weaning protocol showed a reduction in opioid duration and exposure (although not statistically significant). At this point, dexmedetomidine and clonidine should not be introduced outside standardized protocols with scheduled acetaminophen post‐operatively. [ABSTRACT FROM AUTHOR]
