About this study
Official title: Effects of Individualized Opioid Analgesia Versus Conventional Opioid Analgesia After Adenotonsillectomy in Children
The objective of this randomized clinical trial is to assess the safety and effectiveness of post-adenotonsillectomy analgesia with individualized opioid analgesia regime in children.
Read the detailed description
Patients will be randomly assigned to individualized opioid analgesia regimen group or conventional opioid analgesia regimen group.
Intravenous 1μg/kg fentanyl is administered as a test in patients with spontaneous breath after sevoflurane induction. A positive result is defined as a decrease of more than 50% in spontaneous respiratory rate (rate after fentanyl test versus rate before fentanyl test). Otherwise it is defined as a negative result.
All the patients are given regular paracetamol and ibuprofen after surgery. The addition of rescue oral morphine is given as needed. The dose of oral morphine is determined according to the results of fentanyl test in the individualized group, while the patients in the conventional group are given the routine dose. The Faces Scale is used to assess analgesic effectiveness by parents from postoperative day 1 to day 10. If the Faces Scale score > 6, the child receive rescue oral morphine analgesia.
At the preoperative appointment, parents are provided with a pulse oximeter including oxygen saturation sensors to take home. The oxygen saturation per night during sleep will be monitored using the pulse oximeter by parents from postoperative Day 1 to Day 10. The research team will instruct parents on how to properly apply the oximeter to the child and repeat these measurements. The primary outcome measure is desaturation events during sleep per night.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Individualized oral morphineDrug
Also called Individualized group
Analgesic effectiveness is assessed using the Faces Scale by the parents every four hours from postoperative Day 1 to Day 10 (eg: 8:00, 12:00, 16:00, and 20:00, each day).
If the Faces Scale score > 6, the child receive rescue oral morphine analgesia. Patients with positive results of fentanyl test receive oral morphine 100μg/kg per dose, while patients with negative results receive oral morphine 500μg/kg per dose.
Conventional oral morphineDrug
Also called Conventional group
Analgesic effectiveness is assessed using the Faces Scale by the parents every four hours from postoperative Day 1 to Day 10 (eg: 8:00, 12:00, 16:00, and 20:00, each day).
If the Faces Scale score > 6, the child receive rescue oral morphine analgesia. Patients receive oral morphine 200μg/kg per dose.
| Study group | Role | What they receive |
|---|---|---|
| individualized opioid analgesia regimen group | Experimental | The dose of oral morphine for patients in the individualized group is determined according to the results of fentanyl test. Receives: Drug: Individualized oral morphine |
| conventional opioid analgesia regimen group | Active comparator | Patients in the conventional group are given routine dose of oral morphine. Receives: Drug: Conventional oral morphine |
What is being measured
The primary outcome is the main question the study is designed to answer.
Desaturation events
The oxygen saturation per night during sleep will be monitored using a pulse oximeter by the parents from postoperative Day 1 to Day 10. The research team will instruct parents on how to properly apply the oximeter to the child and repeat these measurements. The primary outcome measure is desaturation events during sleep per night.
Measured: from postoperative day 1 to day 10, each night
Secondary outcomes (4)
Scores of Pain Scale (the Faces Scale)
Analgesic effectiveness was assessed using the Faces Scale by the parents every four hours from postoperative Day 1 to Day 10. Parents are trained by the research staff on how to complete pain scale.
Measured: every four hours from postoperative Day 1 to Day 10 (eg: 8:00, 12:00, 16:00, and 20:00, each day)
Scores of Pain Scale (the Objective Pain Scale)
Analgesic effectiveness was assessed using the Objective Pain Scale by the parents every four hours from postoperative Day 1 to Day 10. Parents are trained by the research staff on how to complete pain scale.
Measured: every four hours from postoperative Day 1 to Day 10 (eg: 8:00, 12:00, 16:00, and 20:00, each day)
Tonsillar bleeding events
This include any signs of significant oral or nasal bleeding. It is recorded by the parents as occurring or not; if so, the number of occurrences and the time of each occurrence should be recorded.
Measured: from postoperative day 1 to day 10
Adverse drug reactions
It is recorded by the parents as occurring or not; if so, the time of occurrence and the type of adverse reaction need to be recorded.
Measured: from postoperative day 1 to day 10

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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Desaturation events (time frame: from postoperative day 1 to day 10, each night). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04527393, which also lists 1 linked publication.
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 28 Feb 2024; AzTrials last refreshed its copy on 6 Nov 2026.
