The need for assessment of sedation in the critically ill.

There is a need for assessment of sedation in ICU as sedative agents are potent drugs that are used frequently but not regularly monitored for their efficacy. Critical care nurses are accountable when administering potent intravenous drugs, such as sedative agents. This paper examines the rationale behind the use of sedation in ICU. A number of sedative drugs commonly used in ICU, such as propofol, are highlighted. Sedation assessment tools available are considered but each may be appropriate in different situations.
