Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
All patients were randomly selected to have into two groups. For postoperative analgesia, the first group (n=60) is patients using tramadol (1-2 mgr/ kg, intravenously) at the end of the surgery for postoperative analgesia. It is single dose. The second group is control group, and patients are initially given only fentanyl in the induction for analgesia. Fentanyl (1 µg/ kg, intravenously), propofol (2-3 mgr/ kg, intravenously), and muscle relaxant (rocuronium bromide 0,6 mgr/ kg, intravenously) are administered to all patients for induction as single dose. The medications were given intravenously to each group before awakened were performed by the Anesthesia Care Team.
All the patients’ vital signs were monitored during the operation.
We planned to audit of anesthesia nurse notes to assess or monitor fidelity to the intervention.

Outcomes
Primary outcome [1] 320504 0
A continuous 10 cm visual analog scale (VAS) score was used to determine the level of postoperative pain. On the scale, 0 indicated ‘no pain’, and 10 indicated ‘severe pain’. The patients were asked to mark their pain at different times on the scale, and the results were calculated and recorded in millimeters.
Timepoint [1] 320504 0
Timepoints were the 1st (primary timepoint), 3rd, 7th and 10th hours in postoperative period.
Secondary outcome [1] 371831 0
needed second analgesic agent (Acetaminophen with codeine analgesic 325/ 30 mg. per-oral) timing and amount was recorded in postoperative period. We obtained this data from hospital nurse or physician records.
Timepoint [1] 371831 0
immediately in postoperative recovery room.

Summary
Brief summary
we aimed to investigate whether there is a relationship between opioid receptor level and postoperative pain intensity
120 adult patients underwent septoplasty were randomly divided into preop 2 groups. The first group (n=60) was patients given tramadol (1-2 mgr/kg) for postop analgesia, and the second group (control group)(n=60) was initially performed only fentanyl (1 µg/ kg-i.v.) in the induction.

Results – plain English summary
As the level of the µ-Opioid receptor (µORs) increased in the study groups, the duration of the second analgesic requirement increased. Patients with a high level of µORs experienced less analgesic need in the post-op period. In this study, we found that the efficacy of opioid analgesic agents was higher and the need for additional analgesics was lower in patients with higher µ-Opioid receptor (µORs) levels. This effect was thought to be increased by antidepressant effect. Opioid analgesics combined with steroids also reduced need for second analgesic agents.
