Outline of Final Research Achievements

The purpose of the study is to investigate 1) the relationship between acetaldehyde concentration and microbiome on tongue, and 2) the related factors of tongue pressure decreasing and the effect of tongue excise. The relative abundance of Neisseria flacescens in high acetaldehyde group were significantly greater than those in the low group. The decline of tongue pressure significantly associated with length of intensive care unit (ICU) stay in patients after esophagectomy. The tongue pressure of patients who performed tongue excise were not significantly difference compared with no excise patients. In conclusion, the concentration of acetaldehyde in mouth air was related with Neisseria flavescens. The change of tongue pressure was associated with the length of ICU stay and was not effective from tongue excise in the patients after esophagectomy.
