The effect of bending LPETs on airflow resistance was estimated with a pressure transducer. The force required to pull each tube through the glottis and the pressure exerted during this maneuver were measured in a fresh cadaveric human larynx.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The design features and physical characteristics of LPETs differ, including varying balloon\u2010tip lengths. Bending LPETs to acute angles caused significant pressure increase within the RL tube (\u0394 3.42\u00a0cm H<jats:sub>2<\/jats:sub>O) and minimal change within the ML\u2010II (\u0394 0.12\u00a0cm H<jats:sub>2<\/jats:sub>O) and MTL (\u0394 0.21\u00a0cm H<jats:sub>2<\/jats:sub>O) tubes. The average force required to pull the RL (48.12\u00a0g, <jats:italic>P<\/jats:italic> =. 003) and MTL (282.4\u00a0g, <jats:italic>P<\/jats:italic> =. 001) tubes through the glottis was 7.6\u00d7 and 44.5\u00d7 greater than that for the ML\u2010II (6.39\u00a0g). When pulled through the vocal folds, the ML\u2010II cuff exerted no detectable pressure, whereas higher pressures were measured for the RL (2.2\u00a0cm H<jats:sub>2<\/jats:sub>O) and MTL (6.5\u00a0cm H<jats:sub>2<\/jats:sub>O) tubes.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The ML\u2010II tube had the most favorable characteristics, with minimal pressure during extubation and resistance to kinking. The RL tube kinks readily with a resultant increase in resistance to airflow. The MTL tube extends farther into the trachea due to a relatively elongated balloon\u2010tip configuration. Future LPET designs should incorporate features that avoid intraoperative difficulties related to airway protection and ventilation.<\/jats:p><\/jats:sec>","DOI":"10.1177\/0194599818796106","type":"journal-article","created":{"date-parts":[[2018,8,21]],"date-time":"2018-08-21T17:39:39Z","timestamp":1534873179000},"page":"871-878","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["A
