Predicting Failure of Conservative Airway Management in Infants with Robin Sequence: The EARN Factors.

Evaluate infants with Robin Sequence (RS) who were successfully treated with conservative airway measures alone vs. those who failed and eventually underwent surgical airway intervention after a protracted course of conservative management.Retrospective review of prospectively gathered database.Large tertiary care institution.Infants diagnosed with RS (n = 122) who underwent primary airway management at a single institution from 1994-2020.Patient demographics, nutritional and respiratory status, laboratory values, and polysomnographic results were compared between patients who were discharged after successful conservative airway management (Group 1, n = 61) and patients that underwent surgical airway intervention after failing a prolonged course of conservative management (Group 2, n = 61). Receiver operating characteristic (ROC) curve analysis was done to assess continuous variables that may predict failure of conservative airway management.122 infants with RS were investigated. While several variables were significantly different between groups, the following polysomnographic EARN factors, with cut points, were identified as most predictive of failed conservative airway management: ETCO2 (max) > 49 mmHg, AHI > 16.9 events/hour, OAHI REM >25.9 events/hour, OAHI Non-REM > 23.6 events/hour.We identified factors in infants with RS that were associated with severe UAO that failed to improve despite weeks of conservative airway management. Our results may expedite earlier definitive treatment of these critical patients and reduce risks for known complications of prolonged UAO.
