Feasibility of a Water-soluble Contrast Application Into Dysphagia Evaluation
Feasibility of a Water-soluble Contrast Application Into Dysphagia Evaluation
In traditional video-fluoroscopic-swallowing study, a lipid-soluble contrast (barium sulfate) has been used more than 30 years. However, it can cause chemical pneumonitis and subsequently impair reliability of video-fluoroscopic-swallowing study if aspirated. The authors reviewed the safety and usefulness of an water soluble agent-based swallowing test.
Parallel-group, case-controlled trial was conducted from September 2015 to November 2017. All the patients who referred for video-fluoroscopic-swallowing study were screened.
Based on the pre-emptive evaluation, high-risky patients were allocated to iohexol (Omnipaque)-used video-fluoroscopic-swallowing study and others were allocated to barium sulfate-used video-fluoroscopic-swallowing study.
Statistical Package for the Social Sciences 24 was used to perform statistical analysis for the data. Quantitative data were presented as mean ± standard errors.
