Reduzierende Tage mit Dexmedetomidin als Teil eines Schlaf -Sleep -Promotion -Bündels für die Intensivstation reduzieren (DELDEX)
Eine randomisierte, placebokontrollierte klinische Studie mit Dexmedetomidin als Teil eines Schlaf -Promotion -Bündels zur Verbesserung des Schlafes in der Intensivversorgung
Patients frequently experience problems with sleep while admitted to the ICU. Good sleep is important in ensuring that your immune system responds properly to infection, for your heart to function optimally, and to support normal brain function such as memory.
To address sleep problems in the ICU, a bundle of interventions to support more normal sleep are provided. These bundles consist of medications such as sedatives and environmental changes such as less frequent times being assessed overnight and noise reduction strategies. Although medications can make patients appear to be sleeping, most medications do not provide patients with restful sleep. More research is needed on medications that better mimick restful sleep. One such medication is dexmedetomidine. When formally measured dexmedetomidine can make sleep appear more like a patient sleeping at home as compared to the hospital.
The purpose of this study is to test whether giving a patient in the intensive care unit dexmedetomidine helps have a more restful sleep and possibly be more alert and/or interactive the next day.
To see if dexmedetomidine improves sleep, the investigators will compare the quality of sleep of two different groups of participants: one group that receives dexmedetomidine at night for 2 nights in a row and another group that does not. How well one sleeps will be measured, in either group, will be assessed by a portable sleep machine that is attached by several stickers.
This study is called a pilot or feasibility study. A pilot study assesses how easy it is to recruit patients, whether the sleep machine is tolerated, and amount of time sleep is measured.
It is anticipated that about 50 people will take part in this study. This study should take approximately 2 years to complete, and the results should be known in about 1-2 years thereafter.

Experimental: Intervention
Dexmedetomidine will be prepared at a concentration of 4 mcg/ml by diluting 200 mcg/2 ml vials with 48 mL of 0.9% normal saline to a total volume of 50 ml. A maintenance infusion of 0.2-1.2 mcg/kg/hr will be initiated to sustain the sedative effect and promote sleep throughout the trial period. ICU nurses are experienced in titrating dexmedetomidine for both patients on high flow oxygen (optiflow) and intubated patients with delirium as part of routine care. |

ICU nurses are experienced in titrating dexmedetomidine for both patients on high flow oxygen (Optiflow) and intubated patients with delirium as part of routine care. The ICU bedside nurse will be responsible for using the lowest effective dose to achieve a Richmond Agitation Sedation Scale (RASS) of -2, up to a maximum of 1.2 mcg/kg/hr, while monitoring for adverse events such as bradycardia and hypotension. |

Placebo-Komparator: Control
Patients randomized to the control group will receive a placebo daily for 2 consecutive nights. |
The control group will receive an infusion of 0.9% saline at 5-45 ml/hr titrated to the lowest effective dose to achieve a RASS of -2 for two nights following randomization. |

Protocol Adherence
Zeitfenster: 2 years
|
Adherence to treatment duration protocol: The investigators will consider the main trial to be feasible if intervention is delivered 90% of scheduled duration (proportion of total hours study drug received during intervention period (20:00 - 06:00). Further, tolerance of Prodigy Sleep Machine will be evaluated for a similar proportion of time successfully worn (recordings that are of sufficient quality to permit analyses between 20:00 - 06:00). The investigators will report proportion of adherence with 95% confidence intervals. |

Sleep Quality Assessment
Zeitfenster: 2 years
|
We will monitor overnight sleep using the NOXA1s Sleep System. A trained assessor will attach the device at 17:00, remove the device at 08:00 the following morning and reattach at 17:00 later the same day. The patients will undergo the sleep study for one night prior to randomization, if the quality of data is deemed acceptable then they will be randomized to one of the two experimental groups (dexmedetomidine or placebo) and undergo the sleep study for two additional nights for a maximum of three consecutive nights. The sleep assessment will be performed with the associated Noxturnal Sleep Study software. |
