Auswirkung auf Delirium durch den Einsatz von DEXmedetomidin als Erstlinien-Sedierung in der pädiatrischen Intensivmedizin (PEDIADEX)

25. September 2026 aktualisiert von: University Hospital, Tours

Auswirkung auf Delirium durch den Einsatz von DEXmedetomidin als Erstlinien-Sedierung in der pädiatrischen Intensivmedizin: die PEDIADEX randomisierte kontrollierte Studie

The goal of this clinical trial is to learn if dexmedetomidine can reduce delirium in critically ill children, needing mechanical ventilation for more than 12 hours. The main question it aims to answer is :

• Does dexmedetomidine reduce the proportion of children presenting at least one episode of delirium during their intensive care unit (ICU) stay ? Researchers will compare dexmetomidine to midazolam, to see if the use of dexmedetomidine reduces the prevalence of delirium.

Participants will be sedated with midazolam or dexmedetomidine, according to randomization arm, and the rest of sedation is determined by the study protocol.

Detaillierte Beschreibung

- In the experimental group, participants will receive dexmedetomidine as primary sedative, with opioids for analgesia in order to reach sedation within the target range evaluated with the COMFORT B scale every 4 hours.

The initial dose of dexmedetomidine continuous infusion is 0.7 µg/kg/h with increases of 0.2 µg/kg/h if needed associated to an opioid continuous infusion (sufentanil at 0.2 µg/kg/h or morphine at 40 µg/kg/h). A protocol to adjust level of sedation according to the COMFORT B scale will be followed with maximal doses of 1.4 µg/kg/h for dexmedetomidine, 1.5 µg/kg/h for sufentanil and 300 µg/kg/h for morphine. Other drugs like ketamine up to 2 mg/kg/h, propofol, other opioids, midazolam at bolus or small doses (beginning between 20 µg/kg/h and 0.5 mg/h according to age/weight) are possible and will be reported.

- In the control group, participants with invasive ventilation will receive midazolam as first line therapy with opioids in order to reach sedation within the target sedation range evaluated with the COMFORT B scale every 4 hours.

The initial dose of midazolam is 40 µg/kg/h for children <2 years, 60 µg/kg/h for children after 2 years, and 1 mg/h for children >40kg associated with sufentanil at 0.2 µg/kg/h or intravenous morphine at 40 µg/kg/h. A protocol to adjust level of sedation according to the COMFORT B scale will be followed with maximal doses of 200 µg/kg/h and 10 mg/h if >40kg for midazolam and 1.5 µg/kg/h for sufentanil or 300 mcg/kg/h for morphine. Other drugs like ketamine up to 2 mg/kg/h, propofol, other opioids, are possible and noted. In case of failure, addition of dexmedetomidine will be possible only if midazolam is used at maximal doses.

Waffen und Interventionen

Teilnehmergruppe / Arm
Intervention / Behandlung
Experimental: dexmedetomidine

Participants with invasive ventilation will receive dexmedetomidine as primary sedative, with opioids for analgesia in order to reach sedation within the target range evaluated with the COMFORT B scale every 4 hours.

Participants in intervention arm will receive dexmedetomidine as primary sedative. We will assess if there is less delirium in the intervention arm

Aktiver Komparator: midazolam

In the control group, participants will receive midazolam as first line therapy with opioids in order to reach sedation within the target sedation range evaluated with the COMFORT B scale every 4 hours

participant will receive midazolam as the comparator group

Was misst die Studie?

Primäre Ergebnismessungen

Ergebnis Maßnahme
Maßnahmenbeschreibung
Zeitfenster
Proportion of children with at least one episode of delirium during the ICU stay.
Zeitfenster: From enrollment to the end of ICU stay, up to 90 days

Surveillance of delirium is part of the routine neurological monitoring in pediatric ICU. CAPD score is an 8-items scale. A score of 9 points or higher indicates the presence of delirium. We will evaluate the proportion of children with at least one CAPD score higher than 9.

From enrollment to the end of ICU stay, up to 90 days
