Clinical Trial Summary

The objective of ILAN is to assess the safety, feasibility and bronchodilator efficacy of in-line bronchodilator nebulizer delivery with VMN via HFNC system in hypoxemic respiratory failure patients treated with bronchodilators and compare this method to standard-nebulization using a jet nebulizer with a facial mask. The investigators hypothesized that aerosol nebulization using HFNC/VMN represents safer and more convenient approach in hypoxemic respiratory failure patients in comparison to conventional therapy while providing similar bronchodilator efficacy.


Clinical Trial Description

Objective: To evaluate the safety and feasibility of a novel approach to nebulization treatment via the nasal route in patients with severe hypoxemic respiratory failure dependent on high flow oxygen. Hypothesis: In-line vibrating mesh nebulizer delivery via HFNC systems is a safe, feasible and efficacious approach in comparison to traditional jet nebulizer delivered nebulization in hypoxemic respiratory failure patients whose usual care includes nebulized drugs. Specific Aims: 1. To evaluate the safety and feasibility of administering vibrating mesh nebulizer-delivered therapy in patients with acute hypoxemic respiratory failure requiring high flow nasal cannula. 2. To evaluate the effect of trans-nasal nebulization on patient comfort and satisfaction with therapy in comparison with standard jet nebulization. 3. To evaluate differences in resource utilization between patients receiving standard jet nebulization and ILAN with HF, including time spent at the bedside by the respiratory therapist (RT) for delivery of the medication and any additional time gathering setting up and cleaning. 4. To evaluate patient and therapist perceptions and preference on the various delivery methods of aerosol delivery. Study Design: ILAN is a double-crossover, multi-center trial evaluating the safety and feasibility of in line nebulized medication with high flow nasal canula in comparison to standard jet nebulizer therapy in acute respiratory failure requiring the utilization of high flow nasal cannula. Intervention: Enrolled patients will receive two standard forms of inhaled medications as ordered by the physician. Patients will be randomized into two paths of the cross over study. There will be no blinding involved in this randomization. Path A will have medications delivered trans-nasally in line via the vibrating mesh nebulizer (VMN) with the high flow nasal cannula followed by standard jet nebulization (SJN) with face mask at the next time of medication dosing 3-6 hours later. Path B will receive standard jet nebulization without HFNC followed by the trans-nasal in line nebulization via the HFNC. Patients selected to enroll in day 2 of the trial will have their clinical path alternated in attempt to control for diurnal variability. All patients will also receive as-needed nebulized treatments as well as usual supportive care provided by respiratory therapists. As needed therapy will be delivered via the method of the current arm of the study they are in, and the washout period will subsequently reset. ;
