AbstractBACKGROUND: Tracheal dryness is a concern after total laryngectomy due to the potential for mucus plugs (MP). This study compared heat and moisture exchanger (HME) cassettes to external tracheal humidification (ETH) surrounding MP events. METHODS: A retrospective comparative cohort study comparing outcomes before/after implementation of a patient safety initiative utilizing HME during post laryngectomy hospitalization. The number of MP events were compared with a pre-implementation control group using ETH. Patient characteristics were analyzed for correlation with MP. RESULTS: The rate of MP was significantly lower in the HME group than ETH (0.13 and 0.38 per 10 inpatient days, respectively, P = .02). The proportion of patients with one or more MP events was also significantly reduced in the HME group (50% ETH and 11% HME, P = .01). Method of humidification was the only significant variable associated with MP on logistic regression modeling (P = .008). CONCLUSIONS: HMEs were superior to ETH for prevention of MP.
