COVID-19: ICU delirium management during SARS-CoV-2 pandemic—pharmacological considerations



by Lauren J. Andrews and Scott T. Benken 

Critical Care volume 24, Article number: 375 (2020) 

Letter:

The recent article by Kotfis and colleagues provides great insight regarding newly identified COVID-related risk factors contributing to ICU delirium, while also presenting valid potential solutions to barriers surrounding the implementation of the ABCDEF safety bundle for ICU liberation [1]. However, we feel that the omission of pertinent medication availability and selection limitations currently afflicting healthcare teams around the world warrants further discussion.
In the setting of medication shortages and anecdotally high sedation requirements in COVID patients, it has become increasingly necessary to utilize various combinations of second-line and adjunct therapy options in order to maintain appropriate levels of sedation, with indications for neuromuscular blockade and prone positioning further exacerbating this need [1]. Keeping the known sedation limitations of dexmedetomidine in mind [2], clinicians may be more inclined to use benzodiazepine infusions if unable to obtain adequate supplies of common first-line agents (e.g., fentanyl, propofol). Despite the well-documented association between benzodiazepines and delirium, this approach may be unavoidable for a large number of institutions. Ketamine may be a possible solution, however, as more data has recently emerged regarding its safety and efficacy as an adjunct therapy for analgosedation [3]….
