Trial design

CTIS Part I — objectives, methods, condition coding

Main objective

Scope: Therapy, Efficacy

To assess if continuous intravenous infusion of dexmedetomidine is effective to reduce the prevalence of delirium in critically ill children, needing mechanical ventilation for more than 12 hours.

Secondary objectives 8

  1. A reducing of the cumulative number of days with a CAPD score higher than 9 (definition of delirium)
  2. Consequences of delirium and differential diagnosis: electroencephalogram, brain imaging, need for antipsychotic drug,
  3. An appropriate sedation score according to the COMFORTB during invasive ventilation with less unplanned extubation
  4. An inferior mechanical ventilation time
  5. An inferior intensive care unit length of stay
  6. An inferior hospital length of stay out of the intensive care unit
  7. An inferior in-hospital mortality
  8. An inferior prevalence of iatrogenic withdrawal syndrome

#TitleAllocationBlindingRoles blindedArms
1 Participant selection and recruitment
The legal representative(s) of eligible patients will be approached within 24h of the initiation of sedation and invasive ventilation. In the event that neither of the two legal representatives is present, and after having taken the necessary steps to contact them: The child may be included urgently by deferring the information and consent (to prosecution) of the two legal representatives and subject to the possible subsequent opinion of the child himself.
Not Applicable None
2 Randomisation and intervention
Included patients will be randomized to dexmedetomidine or midazolam using an online server.
Randomised Controlled None Groupe expérimental: In the experimental group, 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.
Groupe contrôle: 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.
3 Follow-up assessments and visit
The first follow-up visit after extubation collect the percentage of sedation scores in the target sedation range, the cumulative duration in hours of invasive ventilation, the haemodynamic events related to sedation defined by a significant bradycardia or hypotension, the bolus fluid or vasopressors utilization. A urine pregnancy test will be performed for girls of childbearing potential. The second follow-up visit will occur after the cessation of all intravenous sedation, opioids and dexmedetomidine: daily cumulative weight-adjusted dose of IV sedative agents (benzodiazepine, ketamine, propofol, dexmedetomidine) and opioids required. The third follow-up visit will occur at discharge from intensive care: the number of days with a CAPD score higher than or equal to 9, the proportion of delirium, the number of days with a WAT score higher than 3, the need of antipsychotic drugs and the length of intensive care hospitalization The fourth follow-up visit will occur at discharge from hospital: hospital length of stay, hospitalization costs and the in-hospital mortality
Not Applicable None

  3. Percentage of over-sedation
  4. The daily cumulative weight-adjusted dose of IV sedative agents (benzodiazepine, ketamine, propofol) and opioids required in each group.
  5. Number of days exposed to sedatives and opioids
  6. The incidence of iatrogenic withdrawal syndrome
  7. The number of days with CAPD score higher than or equal to 9
