Cardiac Surgery Recovery in Infants Assessed Using Neoneur Feeding System

Safe oral feeding is a challenge for infants born with complex congenital heart disease (CHD). These infants are likely to require tube-assisted feeding at the initiation of enteral feeding and struggle to transition to full oral feeding. Infant post-surgery recovery includes a safe transition to oral feeding without respiratory risk. Neoneur Feeding System, consists of a novel hand-held, mobile phone application, and a cloud based computation, which innovatively measures patterns of oral cavity pressure synchronized with respiration, providing a quantitative assessment of feeding patterns. Yet there has been no quantitative means of measuring this recovery process. The concept of post-surgical recovery model is not new. The adult literature is replete with physiologic and behavioral indicators of recovery. More recently Roy and colleagues introduced a recovery model for post-surgical CHD children to adults using a component metrics of physiologic parameters. We are proposing to develop an infant specific recovery model using feeding patterns using data generated by the Neoneur device. The model, using the lens of behavioral organization, will include feeding measurements from initiation of oral feeding to discharge.

This study will evaluate the association between feeding recovery and clinical assessment of infant behaviors as measured in a brief survey to assess irritability, ability to be soothed, alertness, non-nutritive sucking, and muscle tone. Forty infants will be recruited from the PCICU-CSD at MUSC to capture thirty usable infant sets of Neoneur data from the PCICU-CSD at MUSC. This data will be assessed using the Neoneur Feeding System to create a model of feeding recovery.
