Hamzic S, Braun T, Butz M, et al. - Since the prevalence of dysphagia in acute stroke patients undergoing transesophageal echocardiography (TEE) remains unknown, researchers conducted this prospective, blind, randomized, controlled trial (T.E.D.R.A.S.) to evaluate the influence of TEE on swallowing among acute stroke patients. Swallowing was examined utilizing Flexible Endoscopic Evaluation of Swallowing (FEES) at three different intervals in the intervention group (IG) (24 hours before, immediately after and 24 hours after TEE) and within the control group (CG) (FEES on three consecutive days and TEE earliest after the last FEES). Thirty-four patients were randomized in the IG (n = 19) and the CG (n = 15). The findings show a detrimental effect of TEE on swallowing for at least hours in patients with acute stroke.
