Previous studies have showed that patients under mechanical ventilation have a higher risk for experiencing delirium than nonmechanically ventilated patients (20%-50%). Its occurrence is also more frequent in elder patients. More than that, it is often hard to identify delirium by physicians, leading to unreasonable management of ICU patients.~And delirium is one of main adverse events in ventilated patients who receive long-term usage of mono-sedative. Sequential sedation may reduce these adverse effects.~However, few present studies focus on delirium in sequential sedation patients. Thus, in this study, we aimed to determine the factors of delirium in patients who received sequential sedation in ICU.
Delirium is one of main adverse events in ventilated patients who receive long-term usage of mono-sedative. Sequential sedation may reduce these adverse effects. This study aimed to evaluate incidence and risk factors for delirium in sequential sedation patients.
