Aspiration in acute stroke: a clinical study with videofluoroscopy.
To assess the incidence of lung aspiration in acute stroke, and attempt to identify factors which render such patients at risk of aspiration, consecutive patients admitted to hospital within 24 h of their first symptomatic stroke were studied prospectively. Sixty patients who were conscious, and who did not have any preceding neurological or other cause of dysphagia, were assessed clinically and underwent a bedside water-swallowing test and videofluoroscopy within 72 h of stroke. Twenty-five patients (42%) were seen to aspirate at videofluoroscopy; of these 20% did not have overt dysphagia as detected by a simple water-swallowing test. Factors found to be significantly associated with aspiration were reduced pharyngeal sensation, dysphagia and stroke severity. Aspiration is common in the early period following acute stroke; disordered pharyngeal sensation is an important concomitant of this and should be carefully tested in each patient admitted with acute stroke.
