Delirium in critically ill patients with COVID-19 pneumonia

The ICU delirium is a predictor of mortality, length of stay in hospital, time on ventilation, and long-term cognitive impairment. There is a well-established association between acute respiratory distress syndrome (ARDS) and ICU delirium. However, the profile and disease progression trajectory of COVID-19 patients with ICU delirium has not been studied. This case series reviews our institution's experience in COVID-19 patients with ICU delirium. Of all four patients, two of them died in hospital, and the other two survived to the hospital discharge. The disease progressions were tracked, as well as the ICU delirium. Potential life-threatening complications and organ failure symptoms were also presented. To improve the patients' overall health outcome, Haloperidol was prescribed with careful consideration.
