About

To evaluate whether ketamine is a safe sedative-analgesic agent to be used in an intensive care unit (ICU) setting as compared to traditionally used agents such as propofol, opioids, and midazolam

Full description

According to the 2018 Clinical Practice Guidelines for the prevention and management of pain, agitation/sedation, delirium, immobility, and sleep disruption in adult patients in the intensive care unit (ICU), nonbenzodiazepine sedatives (such as propofol and dexmedetomidine) are preferable to benzodiazepine sedatives (such as midazolam and lorazepam) in critically ill, mechanically ventilated patients. Moreover, continuous use of benzodiazepine (more than 48 hours) has been associated with a risk of prolonged sedation and delirium. On the other hand, though propofol has a remarkable safety profile, it carries unfavorable side effects such as dose-dependent hypotension, hypertriglyceridemia, pancreatitis, and propofol syndrome (which is a rare but potentially fatal complication, associated with high-dose propofol infusions, and characterized by severe metabolic acidosis and circulatory collapse).

During the coronavirus disease 2019 (COVID-19) pandemic, an enormous number of patients required mechanical ventilation, which led to the shortage of traditional sedatives such as propofol, dexmedetomidine, midazolam, and lorazepam in the hospitals. In this challenging time, ketamine was used as an alternative sedative infusion. This study is to evaluate whether ketamine is safer compared to other sedatives in severe COVID related ARDS patients.
