Trans esophageal echocardiography increases dysphagia risk in stroke patients: Study

Swallowing was tested using flexible endoscopic evaluation of swallowing (FEES) at three different time points in the intervention group (24 h before, immediately after and 24 h after TEE) and in the control group (FEES on three consecutive days and TEE earliest after the third FEES). Validated scales were used to assess dysphagia severity for all time points as primary outcome measures. 

The key findings of the repeated‐measures between‐group comparisons were significant increases in the intervention group for the following dysphagia measures: (1) secretion severity score and (2) Penetration‐Aspiration Scale score for saliva for the small and large liquid boil. 

"The results indicate a negative influence of TEE on swallowing in acute stroke patients for at least 24 hours," concluded the authors.
