Dysphagia in acute stroke: Correlation with stroke subtype, vascular territory and in-hospital respiratory morbidity and mortality

Aims: The study aimed at correlation of post-stroke dysphagia with area and volume of infarct/ bleed, and with subsequent in-hospital respiratory morbidity and mortality. Materials and Methods: 50 patients of acute stroke were serially recruited. Standard Staff swallowing assessment was performed within 24 hours of admission along with pulse oximetry. Ischemic strokes were classified as per OCPS registry. In-hospital respiratory morbidity and mortality, mode of nutrition and disability status at discharge were noted. Results: 21/50 (42) patients had post-stroke dysphagia during their hospital course. Among infarcts, Total Anterior Circulation Infarcts (TACI) had 100 incidence of dysphagia, followed by Partial Anterior Circulation Infarcts (PACI-36), Posterior Circulation infarcts (POCI-33), and Lacunar infarcts (LACI-18). 67 of hemorrhages had post-stroke dysphagia. Staff swallowing assessment had a sensitivity and specificity of 75 and 73 respy., for predicting respiratory morbidity. The corresponding figures for Pulse oximetry were 79 and 91.
