Impaired swallowing in infants can impact upon the ability to feed orally, often resulting in dependency on supplementary feeding. Such difficulties can lead to an increased burden of care and associated costs. The primary aim of this study was to investigate the impact of vocal cord palsy (VCP), acquired intraoperatively during cardiac surgery, on the feeding outcomes of infants at a tertiary metropolitan children’s hospital. An additional aim was to obtain preliminary information on the impact of feeding difficulties in this group on the quality of life of parents and families. A review of 48 patients who had been referred to the speech pathology service was undertaken. Participants presented with heterogeneous cardiac diagnoses, and had an initial Videofluoroscopic Swallow Study (VFSS) at a median corrected age of 3.6 weeks. Sixty percent of participants presented with silent aspiration on VFSS. Thirty percent of participants required supplementary tube feeding more than 6 months post-surgery. Six percent of participants with poor feeding progress and persistent aspiration required further surgical intervention to support nutrition. Findings revealed no significant relationship between participant factors and the presence of feeding difficulties, however, infants with concomitant genetic and syndromic conditions were found to be most at-risk for long-term feeding difficulties. Analysis of informal parent questionnaire responses indicated parents experienced stress and anxiety after their child’s discharge. This was noted in regard to their child’s feeding, which impacts quality of life across a number of domains. Findings of this study highlight the importance of communicating the potential feeding difficulties to parents of at-risk infants prior to cardiac surgery. This study further highlighted the importance of routine post-operative otorhinolaryngology examinations following high-risk surgeries, as well as speech pathology management for all infants and children identified with VCP. Post-operative input from appropriately trained Speech Pathologists is vital in assisting parents to support and mitigate their child’s difficulties through the provision of early intervention for feeding difficulties.
