Dysphagia After Transesophageal Echocardiography in Acute Stroke - Follow Up Trial

"Flexible Endoscopic Evaluation of Swallowing (FEES):~FEES is performed for analysis of swallowing ability according to the same methodology as in the initial trial: one day before a TEE and max. 4 hours after TEE. Before the FEES anticongestive nose drops are applied and the nostrils are anaesthetized by applying a lidocaine gel via cotton sticks. During the FEES examination the participants sit upright and are asked to swallow various consistencies: FEES is aborted in case of aspiration of any of the consistencies during the examination.~Transesophageal Ecocardiography (TEE):~For the TEE anesthesia is applied via intravenous injection of propofol or a combined anesthesia, through intravenous application of propofol and local anesthesia, using lidocaine spray. All patients undergoing a TEE are sober before and at least two to four hours after TEE."
