About this study
66 female patients undergoing breast cancer surgery were randomized in the Jules Bordet Institute, the Belgian oncology institute. One group received an opioid anesthesia, the other group an opioid free one. The hypothesis of this study was that opioid free anesthesia improves the postoperative quality of recovery of anesthesia.
Read the detailed description
Opioids used as part of balanced anesthesia have known undesired side effects such as: respiratory depression, post-operative nausea and vomiting, pruritus, difficulty voiding and ileus.
The purpose of this study was to determine whether opioid free anesthesia influences the quality of recovery. A multimodal approach combining ketamine, lidocaine and clonidine was used as an alternative for an opioid based anesthesia.
The hypothesis of this study was that patient comfort and satisfaction level after an opioid free anesthesia would be higher compared to after a more traditional opioid anesthesia.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
OFAOther
| Study group | Role | What they receive |
|---|---|---|
| OFA (opioid free anesthesia) | Experimental | All drugs were given IV. Induction in the opioid free group began with a loading dose of clonidine (0.2 mcg kg-1), a bolus of ketamine (0.3 mg kg -1) lidocaine (1.5 mg kg -1) and a bolus of propofol (2-3 mg kg -1).
General anesthesia was maintained with sevoflurane (MAC: 1) (adapted according to hemodynamic stability).
Upon the incision, acetaminophen (1000 mg) and diclofenac (75 mg) were given in both groups. A bolus of ketamine (0.2mg kg -1) was given if necessary in the opioid free group (up to three bolus max. were permitted).
A bolus of piritramide (0.03 mg kg -1) was administered upon subcutaneous closure.
Postoperative pain was treated with IV acetaminophen (1000 mg) every 6 h for the first 24 hours and IV diclofenac (75 mg) every 12 h for the first 24 hours. Patients received a PCIA (patient-controlled intravenous analgesia) pump of piritramide. Receives: Other: OFA |
| OA (opioid anesthesia) | No intervention | All drugs were given IV. Induction in the opioid group began with remifentanil TCI, a bolus of ketamine (0.3 mg kg -1) lidocaine (1.5 mg kg -1) and a bolus of propofol (2-3 mg kg -1). General anesthesia was maintained with sevoflurane (MAC: 1). Upon the incision, acetaminophen (1000 mg) and diclofenac (75 mg) were given in both groups.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.

One group received an opioid anesthesia, the other group an opioid free one. The hypothesis of this study was that opioid free anesthesia improves the postoperative quality of recovery of anesthesia.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing OFA in people with Anesthesia, run by Université Libre de Bruxelles at 1 site in Belgium.
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 1 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: finished, as of the sponsor's last update on 29 Aug 2016. 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 Belgium. 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?
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?
QoR-40 (time frame: 24 hours post-operatively). 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 29 Aug 2016; AzTrials last refreshed its copy on 7 Nov 2026.
