- Abstract
Objectives/Hypothesis: To describe the use of capillary blood gas (CBG) sampling to detect and quantify hypoventilation in infants with Robin sequence (RS). Methods: Case series with chart review at two institutions. Infants with RS presenting over a 10‐year period were identified using departmental databases. CBG values obtained during infancy or until airway intervention (AI) were reviewed. Results: From 2008 to 2018, 111 infants with RS were identified as having had been assessed and managed from birth or transfer until discharge home and having CBG data available. In most cases, CBG sampling was obtained every other day until intervention or discharge. A total of 81 (73%) infants required AI: 72 (89%) underwent mandibular distraction osteogenesis, five (6%) underwent tracheotomy, and four (5%) were discharged home with a nasopharyngeal airway. The mean PCO2 at day of life (DOL) 7–30 for the AI group was 52.7 mmHg (95% confidence interval: 51.7–53.7) and for the no AI group was 45.9 mmHg (44.8–47.0; P <.0001). The mean HCO3 at DOL 7–30 for the AI group was 29.8 mEq/L (29.4–30.1) and for the no AI group was 27.0 mEq/L (26.5–27.4; P <.0001). Receiver operating characteristic curves were created for maximum PCO2 and HCO3 values and cutoffs were established by optimizing a balance of sensitivity and specificity. Infants requiring AI surpassed the PCO2 and HCO3 cutoff at a median of DOL 9. Conclusions: Among infants with RS and hypoventilation, objective measures of respiratory acidosis may be apparent by DOL 9. Level of Evidence: 4 Laryngoscope, 131:2789–2794, 2021
