This study is testing a new automated system for giving propofol to ICU patients on ventilators to see if it can keep them deeply sedated with less medication than usual methods.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are patients requiring deep sedation for more than 48 hours in an ICU setting.

Probably not a fit

Patients with conditions such as dementia, cranial surgery, or those allergic to propofol may not benefit from this study.

What this trial studies

This clinical trial evaluates a minimum viable prototype designed for automated closed-loop administration of propofol in patients requiring deep sedation while on invasive mechanical ventilation in the ICU. Participants will experience both open-loop and closed-loop propofol administration in a randomized matched pair design over a 12-hour period. The study aims to determine if the automated system can maintain deep sedation effectively while minimizing the dosage of propofol compared to standard sedation practices.

Why it matters

Potential benefit: If successful, this approach could lead to safer and more efficient sedation practices in critically ill patients.

How similar studies have gone: While the concept of automated sedation has been explored, this specific prototype's effectiveness in a clinical setting remains novel and untested.
