Surgery Clinical Trial - Dexmedetomidine & Outcomes of Elderly Admitted to

Status Recruiting

Clinical Trial Summary

Sleep disorder and delirium are common problems in intensive care unit (ICU) patients, and may lead to poor prognosis. The investigators' previous study showed that nighttime infusion of low-dose dexmedetomidine improved the sleep quality and decreased the incidence of delirium in ICU patients after surgery. Long-term follow-up of these patients showed that low-dose dexmedetomidine also improved 2-year survival and the quality of life in 3-year survivors. The purpose of this study is to investigate the effect of low-dose dexmedetomidine on the long-term outcome of elderly patients admitted to the ICU after noncardiac surgery.

Clinical Trial Description

Dexmedetomidine is a highly selective α2-adrenoceptor agonist with sedative, analgesic and anti-anxiety properties. Unlike other sedative agents, dexmedetomidine exerts its sedative effects through an endogenous sleep-promoting pathway, producing a state like non-rapid eye movement sleep. For mechanically ventilated patients, sedative-dose dexmedetomidine infusion at night maintains circadian rhythm, increases sleep efficiency, and improves sleep architecture. When used for sedation in mechanical ventilated patients, it reduces the incidence of delirium. Dexmedetomidine may improve patient outcomes by improving sleep quality. A previous randomized trial found that, for elderly patients who were admitted to ICU after noncardiac surgery, nighttime infusion of low-dose dexmedetomidine significantly improves the sleep quality and decreases the incidence of postoperative delirium. A long-term follow-up of these patients showed that low-dose dexmedetomidine infusion significantly increased survival up to 2 years, and improved cognitive function and quality of life in 3-year survivors. In the study mentioned above, dexmedetomidine was only infused during the night after surgery with a fixed dose. The investigators hypothesize that, for elderly admitted to ICU after surgery, nighttime infusion of individualized low-dose dexmedetomidine may improve long-term outcomes. This randomized controlled trial is designed to investigate the effect of low-dose dexmedetomidine on 1-year survival and the quality of life of 1-year survivors in elderly patients admitted to the ICU after surgery. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
