Abstract

Objective: The objective of this study was to systematically review the literature regarding vocal fold motion impairment (VFMI), respiratory outcomes, and swallowing outcomes in children following congenital heart surgery (CHS). Data Sources: PubMed, Embase, Medline, and CINAHL databases. Review Methods: Data sources were searched from inception to November 30, 2018. Studies that described recovery of VFMI and swallowing function following CHS were included, and a qualitative analysis was performed. Results: A total of 1371 studies were identified, of which 8 met inclusion criteria for VFMI and 5 met inclusion criteria for swallowing outcomes. Studies including patients who underwent isolate patent ductus arteriosus ligation were excluded. VFMI was present in 8% to 59% of subjects, and rates of recovery ranged from 9% to 96% at 6 months to 6 years of follow-up. Inability to maintain an oral diet occurred in 14% to 100% of subjects with VFMI and 11% to 61% without VFMI following surgery. Tolerance of an oral diet without tube feeding was present in 66% to 75% of subjects with VFMI and 88% to 100% without VFMI at 24 days to 3.2 years of follow-up. Limited data suggest that time to extubation is longer in VFMI subjects, but overall hospital length of stay and mortality may not be affected by VFMI status. Conclusions: Data evaluating dysphagia and VFMI after CHS are limited. Most studies suggest significant improvement in swallowing function, while rate of recovery of VFMI is variable. Future prospective studies with standardized screening and follow-up are needed to better elucidate outcomes to help develop algorithms for identification and management of VFMI after CHS.
