Why is sedation important for a ventilated patient?

A primary reason to use sedatives in patients receiving mechanical ventilation is to reduce the physiological stress of respiratory failure and improve the tolerance of invasive life support. Optimally, the goal of a stable physiological status should be achieved regardless of the level of sedation.

Can patients hear when sedated?

Nursing and other medical staff usually talk to sedated people and tell them what is happening as they may be able to hear even if they can’t respond. Some people had only vague memories whilst under sedation. They’d heard voices but couldn’t remember the conversations or the people involved.

Is sedation necessary for ventilator?

Most patients receiving mechanical ventilation need sedation given by means of continuous infusion or scheduled dosing to help with anxiety and psychological stress inherent with this intervention. Daily interruption of sedation, when clinically allowable, decreases the number of days of mechanical ventilation.

How long does it take to come out of sedation in ICU?

All patients received continuous sedation and were sedated longer than 7 days. The median duration of sedation before discontinuation of sedation was 12 days (interquartile range 7–14 days).

Light sedation: Awakens briefly (less than 10 seconds) with eye contact to verbal command. Moderate sedation: Any movement, except eye contact, in response to command. Deep sedation: No response to voice, but any movement to physical stimulation. Unarousable: No response to voice or physical stimulation.

Nearly 80% of patients who stay in the ICU for a prolonged period—often heavily sedated and ventilated—experience cognitive problems a year or more later, according to a new study in NEJM.
