Y. Kropp, K. Barthel, G. Beck, M. Thiel, C. Tsagogiorgas, M. Otto

TL;DR
This study compares different methods of delivering aerosol therapy to tracheostomized patients who are breathing on their own.
Contribution
The study identifies the most effective aerosol delivery method for spontaneously breathing tracheostomized patients using an in vitro model.
Findings
The mesh nebulizer achieved the highest drug deposition rate (19.32%) when connected directly to the tracheostomy tube.
The mesh nebulizer's performance was significantly better than the jet nebulizer's best performance (12.33%).
Abstract
Die Aerosoltherapie kommt bei tracheotomierten Patient:innen regelhaft zum Einsatz, z. B. im prolongierten Weaning. Vernebelte Medikamente sollen u. a. die mukoziliäre Clearance verbessern oder eine Bronchoobstruktion behandeln. Es existieren allerdings keine Empfehlungen, wie die Verneblungstherapie bei dieser Patientengruppe am besten durchgeführt werden sollte. Ziel der In-vitro-Studie war es herauszufinden, mit welchem Aerosolgenerator und über welches Interface die Medikamentendepositionsrate bei spontan atmenden, tracheotomierten Patient:innen am höchsten ist. Die Medikamentendepositionsraten eines Jet- (Cirrus™ 2, Intersurgical Beatmungsgeräte GmbH, Sankt Augustin, DE) und eines Vibrating-mesh-Verneblers (Aerogen® Solo, Aerogen Ltd., Galway, IE) wurden in einem In-vitro-Modell spontan und Raumluft atmender, tracheotomierter Patient:innen verglichen. Das Aerosol wurde sowohl…
