From: The role of osmolality in saline fluid nebulization after tracheostomy: time for changing?
HE staining and SEM assay on the histological changes after nebulization intervention (a) HE staining analysis on trachea structure changes within a week after tracheostomy. b SEM analysis on the changes of cilia and mucosa in the early stage after tracheostomy (*p < 0.001 vs. Sham). c The changes on the white blood cell counts in HE staining after intervention (***p < 0.01 vs. Sham). d The changes on the damage area of cilia and mucosa in the SEM after intervention (***p < 0.001 vs. Sham)
