About

Dysphagia (swallowing impairment) is a common complication of cardiothoracic surgery (CS). Although alterations in respiratory-swallow coordination is a known underlying pathophysiologic mechanism of dysphagia in multiple patient populations, no group has examined respiratory-swallow physiology in CS patients. The proposed study will examine respiratory-swallow physiology in CS patients and determine its association with unsafe swallowing and inferior health-related outcomes.

Full description

The proposed study will examine respiratory-swallow physiology in cardiothoracic surgical patients and determine its association with unsafe swallowing and inferior health-related outcomes. Participation will involve a single postoperative research exam of approximately 60-90 minute duration. Participants will be seated upright and positioned for simultaneous instrumental imaging of swallow physiology, nasal airflow monitoring, and respiratory inductance plethysmography testing.

Enrollment: 8 patients

Ages: 18 to 90 years old

Trial design

8 participants in 1 patient group

Cardiothoracic surgical patients

Description:

Subjects will undergo one simultaneous instrumental examination of swallowing and concurrent monitoring of metrics of respiratory-swallow physiology. Research exam will be performed at bedside within Cardiac \& Thoracic Intensive Care Units during their early postoperative recovery.

Treatment:

Diagnostic Test: Videofluoroscopic swallow exam with concurrent monitoring of respiratory-swallow coordination
