Sedation of the agitated, critically ill patient without an artificial airway
1Department of Anesthesiology, University of Virginia Health Sciences Center, Charlottesville, USA.
Abstract:
One of the most demanding and stressful situations is management of the agitated, unintubated, critically ill patient. Sedation often must be provided without a specific diagnosis, and the need for rapid airway control must be anticipated. No predictably safe and effective techniques are proven. The experience and skill of the physician managing the patient during sedation are the predictive factors for the best outcome. Even in expert hands, airway compromise and cardiovascular decompensation often occur in these very ill patients. Many techniques for sedation have been described. Treatment of pain followed by small boluses of intravenous sedative agents is a reasonable initial approach. Benzodiazepines have a good safety record and provide good amnesia. Other agents have been used, by themselves or in combination. Haloperidol may have a therapeutic advantage in the disoriented, agitated patient. Prolonged need for significant sedative medication usually mandates a secure airway. Once this is accomplished, the requirement for a continuously present airway expert at the bedside is removed. The standard for sedating a patient without an artificial airway requires a higher level of expertise than sedating a critically ill patient with an artificial airway.

Sedative-hypnotics are categorized into barbiturates, benzodiazepines (BZDs), and non-benzodiazepines or Z-drugs. These drugs work by suppressing central nervous system activity, and this suppression is dose-dependent. Older sedative medications, like barbiturates, follow a linear curve in...

Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
