Inhaled sedation in the intensive care unit: what’s the future for AnaConDa™?

Abstract

Sedation contributes to patient’s comfort and plays an essential role in the intensive care unit (ICU). Several clinical studies have reported the occasional use of volatile halogenated agents in the ICU; however, long-term use is possible in routine for the provision of a dedicated evaporator filter (AnaConDa™ [ACD]). Because of their low cost and pharmacological characteristics with a rapid therapeutic effect, a high therapeutic index, a possible use regardless of age and underlying medical conditions, and a good knowledge of their adverse effects, halogenated agents could be considered like possible ideal anesthetic agents in the ICU. The objective of this technical note is to clarify the potential indications of ACD device and describe its operative principles and potential drawbacks.
