A Targeted Swallow Screen for the Detection of Postoperative Dysphagia in Liver Transplant Patients

Introduction:Postoperative dysphagia leads to aspiration pneumonia, prolonged hospital stay, and is associated with increased mortality. We have demonstrated the validity of a bedside targeted swallow evaluation following cardiac surgery. Since dysphagia following liver transplantation is not well examined, we evaluated the efficacy of this swallow screen method in postoperative liver transplant patients.Methods:This was a prospective trial involving adult patients who underwent liver transplant surgery at our institution over a 5-month period. Within 24 hours of extubation and prior to the initiation of oral intake, all patients were evaluated using the targeted swallow screen, which is a direct assessment of mental status and laryngeal sensation/elevation upon swallowing of progressively larger amounts of water. A fiberoptic endoscopic evaluation of swallowing was requested for failed screenings.Results:During the study, 50 patients were screened. Twenty (40%) failed the targeted swallow screen, while 1...
