Abstract

Objective: We aimed to investigate the effects of dinalbuphine sebacate (DNS), fentanyl-based patient-controlled analgesia (PCA), and conventional analgesia (CA) for pain management after laparotomy for gynecologic cancers. Methods: A total of 137 eligible patients who underwent laparotomy through a midline incision wound for gynecologic cancer between July 2019 and June 2020 were retrospec-tively evaluated. The patients were divided into three groups as follows: the intramuscular DNS, intravenous PCA, and CA groups. Postoperative pain (POP) intensity as measured with a numerical rating scale (NRS), total consumption of analgesics, and incidence of treatment-emergent adverse events were compared between the three groups. Results: The DNS group showed significant reduction in NRS pain intensity than the PCA and CA groups on day 1 (4.8 vs 6.2, p < 0.01 and 6.2, p < 0.05, respectively), day 2 (3.0 vs 4.7, p < 0.01 and 4.8, p < 0.001, respectively), day 3 (2.0 vs 3.9, p < 0.001 and 3.5, p < 0.001, respectively), day 4 (1.1 vs 3.1, p < 0.001 and 2.9, p < 0.001, respectively), and day 5 (0.7 vs 2.3, p < 0.001 and 2.4, p < 0.001, respectively). The total consumption of morphine equivalents per day was similar between the DNS and PCA groups (142.8 ± 7.3 mg vs 137.7 ± 70.0 mg, p = 0.8032) and lowest in the CA group (11.7 ± 30.7 mg, p < 0.0001). The overall safety profile was comparable between the DNS, PCA, and CA groups. The patients in the DNS group complained less of dizziness postoperatively than those in the PCA group (27% vs 47%) and had less nausea than those in the CA group (13% vs 33%). Conclusion: A single DNS injection was more effective for relieving POP than PCA and CA in the patients who had a longitudinal incision for gynecologic cancer surgery. DNS was well tolerated and had less adverse effects than PCA and CA.
