Evaluating the Feasibility and Usability of the Disposable Intubation Drape (I-Drape).

In response to the COVID-19 pandemic, several protective barrier enclosures were developed to protect healthcare providers during airway manipulation. A certified registered nurse anesthetist (CRNA) created a barrier, the disposable intubation drape (I-Drape), that addressed limitations in range of motion. A nonrandomized, quasi-experimental design with repeated measures was used to evaluate I-Drape usability. CRNAs implemented I-Drape up to three times. Multilevel modeling was used to analyze the primary outcome: time (in seconds) to successful intubation. An online survey was used to evaluate secondary outcomes of interest: users' perceptions of features such as usability, visibility, and durability. We recruited 23 CRNAs as participants for 59 trials. Overall successful intubation and first-pass success rates were 96.6% and 93.2%, respectively. Time to successful intubation did not significantly decrease (β = -9.16, P = 0.323) or differ significantly among types of laryngoscopy device and years of experience was not a significant factor. Overall, users favorably rated I-Drape with respect to usability, visibility, durability, and feature utility. This study demonstrated the functionality, success rate, and acceptability of I-Drape. I-Drape can be used safely and efficiently with any type of laryngoscopy device by providers with various experience levels.
