Fentanyl versus morphine for sedation and pain control in adults on mechanical ventilation

Official title: Compare the Efficacy and Outcome Between Fentanyl and Morphine as Analgo-sedation in Mechanically Ventilated Patients

Run by Universiti Sains Malaysia · NCT06479655 · Data updated 2026-11-12

This trial will test whether fentanyl or morphine, given with propofol, helps reach target sedation levels faster and reduces the need for extra sedative doses in adults on mechanical ventilation in the ICU.

Is this trial a fit for you?

Likely a good fit

Adults over 18 admitted to the ICU who are expected to need invasive mechanical ventilation for more than 24 hours and who will start continuous infusion sedation within 12 hours of admission are ideal candidates.

Probably not a fit

Patients with chronic opioid use, severe liver or end-stage renal failure, pregnancy, neuromuscular blockade, severe neurocognitive impairment, drug overdose, known allergy to fentanyl or morphine, or severe traumatic brain injury are excluded and unlikely to benefit from this comparison.

What this trial studies

Adults in the ICU who need invasive mechanical ventilation and continuous infusion sedation within 12 hours of admission are randomized to receive either fentanyl or morphine together with propofol. The proportion of patients reaching the target sedation score at 12 and 24 hours and the proportion requiring rescue sedation doses are recorded. Duration of mechanical ventilation, length of ICU stay, and 14-day mortality are also compared between the two groups. Patients with chronic opioid use, severe liver or end-stage renal failure, pregnancy, neuromuscular blockade, severe neurocognitive dysfunction, drug overdose, known allergy to the drugs, or severe traumatic brain injury are excluded.

Why it matters

Potential benefit: If one drug provides more reliable sedation with fewer rescue doses, it could shorten time on the ventilator and reduce ICU length of stay.

How similar studies have gone: Both fentanyl and morphine are commonly used for ICU sedation and prior studies have produced mixed results, with some suggesting more predictable sedation with fentanyl but no clear mortality advantage for either agent.
