About this study
The primary aim of this clinical trial is to compare the effectiveness of fentanyl vs morphine as analgosedation in mechanically ventilated adult patients in the ICU. This study also aims to compare the outcomes of patients between the two groups.
The main questions it aims to answer are :
- Does propofol and fentanyl infusion as analgo-sedation achieve targeted sedation score at 12 and 24 hours compared to propofol and morphine infusion in mechanically ventilated adult patients in the intensive care unit (ICU)?
- Is there a difference between the proportion of patients requiring rescue sedation dose between the fentanyl and morphine groups?
Read the detailed description
Researchers will randomize patients into 2 groups (Fentanyl and Morphine) and will start study drug accordingly for sedation in ICU.Proportion of patients from each group achieving targeted sedation score at 12 and 24 hours following initiation of the drug and proportion of patients from each group requiring rescue sedation dose will be recorded and analyzed.
Furthemore duration of mechanical ventilation, length of ICU stay and 14 days mortality rate will recorded and compared between this 2 groups of patients.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Fentanyl and Morphine in people with Effect of Drug, run by Universiti Sains Malaysia at 1 site in Malaysia.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 6 Oct 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Malaysia. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Mohd Zulfakar Mazlan Dr, MBBS (+60135335566, zulfakar@usm.my), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
RASS score at 12 and 24 hours (time frame: 24 hours from study drug initiation). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Oct 2025; AzTrials last refreshed its copy on 6 Nov 2026.
