Acute impact of lung transplantation on respiratory-swallow coordination, swallowing impairment, and airway invasion: A prospective cohort study.

ABSTRACT:

Background

Lung transplant recipients possess premorbid risk factors for swallowing impairment and airway invasion, including potential alterations in respiratory-swallow coordination. Although aspiration is highly prevalent after lung transplantation, the impact of lung transplantation, its procedures, and postoperative pain management on respiration and swallowing are not understood.

Methods

A prospective cohort study of adult lung transplant recipients referred for pre- and postoperative modified barium swallow studies. Respiratory signals were synchronously captured with videofluoroscopic images and analyzed to determine the respiratory phase preceding swallowing events. Swallowing impairment and airway invasion were analyzed using the Modified Barium Swallow Impairment
