Abstract
Objective
This study was designed to investigate the effect of butorphanol-soaked nasal packing on analgesia and sleep quality in patients undergoing bilateral endoscopic nasal surgery.
Methods
Sixty-six patients were enrolled and randomly allocated into three groups: group B1 (butorphanol 0.03 mg/kg), group B2 (butorphanol 0.04 mg/kg) and group N (control group). The primary outcome was postoperative pain scores evaluated by a Visual Analogue Scale (VAS) at 2 h (T1), 8 h (T2), 24 h (T3) and 48 h (T4) after surgery. Secondary outcome was postoperative sleep quality measured using Subjective Sleep Quality Value (SSQV).
Results
Postoperative VAS scores of butorphanol groups were significantly lower than the control group at T2, T3 and T4. VAS scores at each time point did not differ between groups B1 and B2. On the first and second nights after surgery, SSQV was higher in butorphanol groups than in the control group. There were no significant differences in SSQV1 and SSQV2 between group B1 and group B2. The incidence of respiratory depression, dizziness, agitation and rescue analgesic use did not show difference among three groups.
Conclusions
Butorphanol-soaked nasal packing can reduce pain and improve sleep quality after bilateral endoscopic nasal surgery without increasing adverse effects. A concentration of 0.03 mg/kg may be appropriate for clinical application.
Level of Evidence
Level 1B.

Highlights
Butorphanol-soaked nasal packing can reduce pain and improve sleep quality.
Butorphanol-soaked nasal packing does not increase adverse effects after surgery.
0.03 mg/kg butorphanol may be more appropriate for clinical use than 0.04 mg/kg.
