Condition(s) targeted: Respiratory Insufficiency; Respiration, Artificial; Conscious Sedation

Intervention: remifentanil (Drug); placebo (Drug)

Phase: Phase 4

Status: Completed

Sedation is widely used in mechanically ventilated patients. Propofol, benzodiazepines and opioids are the most used drugs. The study hypothesis is that sedation with remifentanil (an opioid drug) could improved respiratory pattern and effort in mechanically ventilated patients with rapid shallow breathing or high respiratory rate.
