    48. 50. Conclusions <ul><li>Oversedation in the ICU is common; associated with negative sequelae </li></ul><ul><li>Monitor and treat pain and delirium prior to administering sedation therapy </li></ul><ul><li>Analgosedation has been shown to improve outcomes; consider sedation only if necessary </li></ul><ul><li>Titrate all sedative medications using a validated assessment tool to keep patients comfortable and arousable if possible </li></ul><ul><li>Monitor for adverse events </li></ul>
    49. 51. Conclusions <ul><li>ICU sedation should use protocols that include a down-titration and/or daily interruption strategy coupled with a spontaneous breathing trial </li></ul><ul><li>Multiple sedatives are available </li></ul><ul><li>Propofol and dexmedetomidine will liberate patients from mechanical ventilation faster than benzodiazepine therapy (even when administered intermittently) and are associated with less delirium </li></ul><ul><li>Use of benzodiazepines should be minimized </li></ul>
    50. 52. Conclusions <ul><li>Cost of care calculations should consider the overall costs, not just drug acquisition costs </li></ul><ul><li>Early mobility in ICU patients decreases delirium and improves functional outcomes at discharge </li></ul><ul><li>Consider non-pharmacological management of delirium and reduce exposure to risk factors </li></ul><ul><li>Typical and atypical antipsychotic medications may be used to treat delirium if non-pharmacological interventions are not adequate </li></ul>
