Laryngotracheal stenosis (LTS) is the luminal compromise at the laryngeal, subglottic, or tracheal level (Gelbard et al., 2014). Various etiologies for LTS exist. Endotracheal cuff over-inflation, inappropriately sized endotracheal tubes, and sudden movements of the tube contribute to injury, as well as anatomical differences(Cardillo et al., 2010; Divatia & Bhowmick, 2005; Medina et al., 2009; Miñambres et al., 2009; Nikolovski et al., 2019; Zaghi et al.,2016). The influence of estrogen may contribute to the development of LTS in women during the third through fifth decades Dedo & Catten, 2001; Poetker et al., 2006; Valdez & Shapshay, 2002). The project goal was to provide an evidence-based presentation to potentially reduce the risk of LTS, at a tertiary care center in central Illinois. A pre- and post-survey was taken by 30 respondents, including nine physicians and 21 certified registered nurse anesthetists (CRNAs). The results of the project showed 100% of the respondents felt more knowledgeable about LTS, and 97% felt the information provided would positively impact practice change. Using a cuff manometer to determine accurate ETTc pressure was not an easily accepted practice change. Future projects could aim to identify specific barriers to cuff manometer use at the facility.
