Analgesia and sedation with remifentanil in adult and aged icu patients mantaining spontaneous ventilation.

Background and Goal of Study: Remifentanil was used for analgesia and sedation in mechanically ventilated ICU patients, nevertheless there is a lack of data about the drug request for analgesia and sedation in adult and aged ICU patients spontaneously breathing. We investigated the dosage of remifentanil for analgesia and sedation in patients maintaining spontaneous ventilation in an intensive care unit and the possible difference in the remifentanil request between adult and aged patients.
