Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Written informed consent obtained from the patient's legal representative according to local regulations before starting any study procedures other than pre-screening
  • Patients sedated and ventilated in ICU for whom sedation is expected to be clinically required for at least 24 hours, as determined by the responsible physician
  • Prescribed light to moderate sedation (target RASS = 0 to -3)

Exclusion Criteria:

  • Acute severe intracranial or spinal neurological disorder due to vascular causes, infection, intracranial expansion or injury
  • Uncompensated acute circulatory failure at screening (severe hypotension with mean arterial pressure(MAP) < 55 mmHg despite vasopressor and inotrope therapy)
  • Heart rate (HR) < 50 beats/min for longer than 5 min between screening and starting study treatment
  • Atrioventricular (AV)-conduction block II-III (unless pacemaker installed)
  • Severe hepatic impairment (e.g. bilirubin > 101 μmol/L)
  • Need for continuous muscle relaxation
  • Any condition which would significantly interfere with the collection of study data
  • Burn injuries or other conditions requiring regular anesthesia or surgery
  • Use of centrally acting alpha-2 agonists or antagonists within 24 hours prior to starting the study (e.g. dexmedetomidine, clonidine, tizanidine, apraclonidine and brimonidine)
  • Known allergy to dexmedetomidine or any excipients of the study treatment
  • Patients who have or are expected to have treatment withdrawn or withheld due to poor prognosis
  • Patients receiving sedation for therapeutic indications rather than to tolerate the ventilator (e.g. epilepsy)
  • Patients unlikely to require continuous sedation during mechanical ventilation (e.g. Guillain-Barré syndrome)
  • Patients who are unlikely to be weaned from mechanical ventilation; e.g. diseases/injuries primarily affecting the neuromuscular function of the respiratory apparatus such as clearly irreversible disease requiring prolonged ventilatory support (e.g. high spinal cord injury or advanced amyotrophic lateral sclerosis)
