Delirium Clinical Trial

Official title: Midazolam Used Alone or Sequential Use of Midazolam and Propofol/Dexmedetomidine for Long-Term Sedation in Critically Ill, Mechanically Ventilated Patients: a Prospective, Randomized Study

Status Enrolling by invitation

Clinical Trial Summary

The purpose of this study was to evaluate effects, safety and cost of midazolam used alone or sequential use of midazolam and propofol/dexmedetomidine for long-term sedation in critically ill, mechanically ventilated patients.

Clinical Trial Description

It is well known that sedation is frequently required as a component of compassionate care in critically ill patients. Until now, there is no ideal sedation drug and every sedation drug has its advantage and disadvantage for long-term sedation in critically ill, mechanically ventilated patients. The sequential use of midazolam and propofol for long-term sedation was associated with a faster recovery, earlier extubation, shorter mechanical ventilation time and less cost of total ICU treatment compared with midazolam alone, The protocol was associated with less cost of pharmaceutical sedation compared with propofol alone. But, propofol and midazolam may cause respiratory depression and delirium. Both drugs should be stopped after the patient passed the screen of weaning from mechanical ventilation, then it would induce the stress response and agitation, it would cause prolonged sedation and delay extubation.

Dexmedetomidine is a centrally acting a2-receptor agonist, has less effect on arousability and respiratory depression. The purpose of this study was to evaluate effects, safety and cost of midazolam used alone or sequential use of midazolam and propofol/dexmedetomidine for long-term sedation in critically ill, mechanically ventilated patients. ;
