About this study
Official title: The Efficacy of the Time-scheduled Decremental Continuous Infusion of Fentanyl for Postoperative Patient-controlled Analgesia After Total Intravenous Anesthesia
We investigated the efficacy and the safety of the pharmacokinetic model-based patient-controlled analgesia (PCA) regimens of fentanyl for postoperative analgesia after total intravenous anesthesia (TIVA).
Read the detailed description
Infusions of fentanyl (2 ml/hr of diluent was equivalent with 0.5 μg/kg/hr of fentanyl) were maintained at the fixed-rate of 2 ml/hr until the postoperative 24 hr, or at the decremental rates of 6.0 ml/hr or 8.0 ml/hr during 1 hr, 4.0 ml/hr during 1~3 hr and 2.0 ml/hr during 3~24 hr, postoperatively.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
FX2-2-2Other
Also called decremental PCA
Their background infusions of fentanyl diluent (2 ml/hr of diluent was equivalent with 0.5 μg/kg/hr of fentanyl) were maintained at the fixed-rate of 2 ml/hr until the postoperative 24 hr (FX2-2-2), or at the decremental rates of 6.0 ml/hr (D6-4-2) and 8.0 ml/hr (D8-4-2) during 1 hr, 4.0 ml/hr during 1~3 hr and 2.0 ml/hr during 3~24 hr, postoperatively. The visual analogue scores (VAS), the incidence of inadequate analgesia, the frequency of intervention of PCA, and side effects were evaluated.
D6-4-2Other
Also called decremantl PCA 6-4-2
Their background infusions of fentanyl diluent (2 ml/hr of diluent was equivalent with 0.5 μg/kg/hr of fentanyl) were maintained at the fixed-rate of 2 ml/hr until the postoperative 24 hr (FX2-2-2), or at the decremental rates of 6.0 ml/hr (D6-4-2) and 8.0 ml/hr (D8-4-2) during 1 hr, 4.0 ml/hr during 1~3 hr and 2.0 ml/hr during 3~24 hr, postoperatively. The visual analogue scores (VAS), the incidence of inadequate analgesia, the frequency of intervention of PCA, and side effects were evaluated.
D8-4-2Other
Also called decremental PCA 8-4-2
Their background infusions of fentanyl diluent (2 ml/hr of diluent was equivalent with 0.5 μg/kg/hr of fentanyl) were maintained at the fixed-rate of 2 ml/hr until the postoperative 24 hr (FX2-2-2), or at the decremental rates of 6.0 ml/hr (D6-4-2) and 8.0 ml/hr (D8-4-2) during 1 hr, 4.0 ml/hr during 1~3 hr and 2.0 ml/hr during 3~24 hr, postoperatively. The visual analogue scores (VAS), the incidence of inadequate analgesia, the frequency of intervention of PCA, and side effects were evaluated.

What is being measured
The primary outcome is the main question the study is designed to answer.
visual analogue scores (VAS)
The assessments of analgesia and patient condition were performed at the time points of immediate post-operative periods (1, 15, 30, 45, and 60 min) and post-operative 2, 3, 4, 6, 12 and 24 hr.
Measured: until post-operative 24 hrs

Questions about this trial
What is this clinical trial studying?
A study testing FX2-2-2, D6-4-2 and D8-4-2 in people with Analgesia Disorder, run by Ajou University School of Medicine at 1 site in South Korea.
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 1 inclusion and 3 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 7 Feb 2013. 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 South Korea. 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.
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?
visual analogue scores (VAS) (time frame: until post-operative 24 hrs). 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 7 Feb 2013.
