Assessment of a novel adhesive baseplate (Provox StabiliBase) for heat and moisture exchanger (HME) and/or automatic speaking valve (ASV) application.
Prospective, clinical, multicenter trial.
This was a trial in laryngectomized patients comparing their usual adhesive with the trial adhesive. Primary outcome measure was overall patient preference; additional outcome parameters possibly explaining patients' preferences were 1) patient tolerance and preference with respect to daily handling of the adhesive; 2) adhesive lifespan, and 3) voice and speech with the adhesives. Study specific questionnaires, visual analog scales, patients' diaries, and stoma assessments were used for data collection.
In total, 58 of the 65 laryngectomized individuals entered in the study completed the trial. Patients' overall preference for the new device was high (76%; P < .001). Significantly better performance was found for the trial adhesive with respect to ease of application (P = .034), fit (P < .001), and air leakage through the adhesive (P < .001). Comfort and stoma depth correlated weakly (r = 0.297; P = .024; deeper stoma-more comfort with StabiliBase). The adhesive lifespan with HME is significantly increased (1.7 times and 15.7 hours-plus airtight use; P < .001). This longer lifespan coincided with somewhat increased dirtying of the adhesive (P = .02). There were no serious adverse events.
The StabiliBase adhesive for peristomal attachment of HMEs and/or ASVs was preferred by 76% of study participants and showed a promising prolonged lifespan. This new device further increases the options for stoma attachment in laryngectomized individuals, and subsequently the availability of optimal voice and pulmonary rehabilitation for a larger proportion of patients.
