AbstractPatients who suffer from dyspnea while dying from COVID-19 are treated with opioids and benzodiazepines. In some instances, patients may experience refractory dyspnea at the end of life. Palliative sedation can be prescribed to alleviate such patients' suffering. We describe two patients being treated for severe COVID-19 pneumonia in a tertiary hospital. Both developed intractable dyspneic crises despite high-dose opioids and benzodiazepines. This led to their requirement of palliative sedation in the general ward using subcutaneous phenobarbitone (phenobarbital). We outline clinical considerations for the use of palliative sedation in COVID-19 related dyspnea. In particular, we discuss the evidence for, benefits and limitations of using phenobarbitone for palliative sedation in COVID-19 patients.
