ClinConnect Summary

This clinical trial, called the mini-MENDS trial, is studying the effects of two different medications used for sedation in infants and children who are on mechanical ventilation in the pediatric ICU. The trial aims to find out whether dexmedetomidine, a medication that works differently than traditional sedatives like midazolam, can reduce delirium—a serious condition affecting the brain—and improve recovery for young patients who are critically ill. Delirium can make recovery harder and increase the time spent in the hospital, so finding the best sedation option is very important.

To be eligible for the trial, participants need to be between 44 weeks post-menstrual age and 11 years old, require mechanical ventilation, and be admitted to the pediatric ICU at Monroe Carell Jr. Children's Hospital at Vanderbilt. However, certain conditions, like severe developmental delays or ongoing sedation for over 72 hours, may prevent participation. If your child is enrolled, they will receive one of the two sedative medications and be closely monitored for how well they respond, with the goal of improving their overall recovery and reducing complications. The trial is currently recruiting participants, and your child's safety and well-being will be the top priority throughout the study.

Eligibility criteria

• Inclusion Criteria:
• • Patients will be eligible for enrollment if they are 1) aged 44 weeks post-menstrual age and up to 11 years, 2) planned admission to the pediatric ICU at Monroe Carell Jr. Children's Hospital at Vanderbilt (MCJCHV), and 3) requiring mechanical ventilation (MV) and sedation. Pre-pubescent children (\<11 years) are typically different from older children who often behave physiologically more similar to adults. Pre-pubescent children are more likely to be admitted to the PICU and are undergoing a steeper curve of neurocognitive maturation. Therefore, these patients may be at greatest risk for worse brain dysfunction.
• Exclusion Criteria: Patients will be excluded (i.e., not approached for consent) if any one is present:
• • 1. Receiving continuous sedation for \> 72 hours prior to screening.
• • 2. Rapidly resolving respiratory failure at screening, with planned immediate liberation from MV.
• • 3. Severe developmental delay at baseline defined as a score of ≥ 4 (severe disability) on the Pediatric Cerebral Performance Category (PCPC) Scale, referencing cognitive status prior to critical illness.
• • 4. Clinically significant 2nd or 3rd degree heart block or bradycardia \< 60 beats per minute.
• • 5. Benzodiazepine dependency with ongoing medical requirement of continuous benzodiazepine (infusion).
• • 6. Inability to co-enroll with another study.
• • 7. Expected death or care plan for withdrawal of support measures within 24 hours of enrollment.
• • 8. Bilateral vision loss.
• • 9. Deafness that will preclude delirium evaluation.
• • 10. Inability to understand English that will preclude delirium evaluation. The inability to understand English in verbal participants will not result in exclusion when the research staff is proficient and/or translation services are actively available in that particular language.
• • 11. Documented allergy to either dexmedetomidine or midazolam.
• • 12. Medical requirement of continuous (infusion) neuromuscular blockade administration that is planned ongoing for at least 48 hours at time of screening.
• 13. Inability to start the informed consent process within the 72 hours from the time that all inclusion criteria were met (possible reasons):
• • 1. Attending physician refusal
• • 2. 72-hour period of eligibility was exceeded before the patient was enrolled
• • 3. Legal Authorized Decision Maker (e.g. legal guardian/power of attorney) refusal
• • 4. Legal Authorized Decision Maker (e.g. legal guardian/power of attorney) unavailable
• • 5. Legal Authorized Decision Maker (e.g. legal guardian/power of attorney) is non-English speaking and available research staff is not proficient and/or translation services are not available in that particular language.
• • 14. Adjusted dosing weight is \> 50 kg at time of screening.
