Abstract:
Methods:To investigate the analgesic efficacy of oxycodone after cesarean section and its effects on pain factors.Methods:A total of 100 pregnant women who underwent cesarean section in Taizhou Hospital of Zhejiang Province from August 2022 to March 2023 were included in this prospective study. They were divided into an observation group ( n = 50) and a control group ( n = 50) using a random number table method. Sufentanil was used for postoperative analgesia in the control group, and oxycodone was used for postoperative pain in the observation group. At 6, 12, 24, and 48 hours after surgery, visual analogue scale (VAS) scores of incision pain and uterine contraction pain and the Ramsay score were compared between the two groups. Before and 48 hours after surgery, pain factors (prostaglandin E 2, substance P, and norepinephrine) were compared between the two groups. At 48 hours after surgery, sleep quality, satisfaction with pain relief, and the incidence of adverse reactions were compared between the two groups. Results:The VAS scores of incision pain in the observation group were lower than those in the control group at the studied time points after surgery [6 hours: (2.35 ± 0.31) points vs. (2.78 ± 0.43) points; 12 hours: (5.08 ± 0.64) points vs. (5.67 ± 0.51) points; 24 hours: (4.76 ± 0.35) points vs. (5.12 ± 0.42) points; 48 hours: (2.18 ± 0.37) points vs. (2.54 ± 0.42) points, t = 5.74, 19.87, 4.66, 4.55, all P < 0.001]. At 6, 12, 24, and 48 hours after surgery, the VAS scores of uterine contraction pain in the observation group were significantly lower than those in the control group at the studied time points after surgery [6 hours: (2.41 ± 0.26) points vs. (2.85 ± 0.32) points; 12 hours: (4.98 ± 0.49) points vs. (5.41 ± 0.65) points; 24 hours: (4.65 ± 0.31) points vs. (4.98 ± 0.28) points; 48 hours: (2.04 ± 0.26) points vs. (2.43 ± 0.30) points, t = 7.55, 3.74, 5.59, 6.95, all P < 0.001]. There was no significant difference in Ramsay score between the two groups at 6, 12, 24, and 48 hours after surgery ( t = 0.44, 0.51, 0.78, 0.42, all P > 0.05). At 48 hours after surgery, prostaglandin E 2, substance P, and norepinephrine levels in the observation group were significantly lower than those in the control group ( t = 14.22, 9.05, 14.74, all P < 0.001). At 48 hours after surgery, The Pittsburgh Sleep Quality Index score in the observation group was significantly higher than that in the control group ( t = 4.64, P < 0.05). The overall satisfaction with postpartum analgesia in the observation group was significantly higher than that in the control group ( χ2 = 4.40, P < 0.05). There was no significant difference in the incidence of adverse reactions between the two groups ( χ2 = 0.33, 1.08, 0.38, 0.33, all P > 0.05). Conclusion:Oxycodone has a better analgesic effect on cesarean sections than sufentanil. Oxycodone can inhibit the release of pain factors and thereby reduce pain.
