The impact of sufentanil versus remifentanil on surgical site wound healing in caesarean section primiparas undergoing epidural anaesthesia: A systematic meta-analysis.

ABSTRACT

Caesarean section (C-section) is a prevalent obstetric surgical procedure, with the choice of analgesic agents playing a pivotal role in postoperative recovery. This systematic meta-analysis aimed to compare the effects of sufentanil (ST) and remifentanil (RT) on postoperative wound healing in caesarean section primiparas undergoing epidural anaesthesia. A comprehensive search was conducted across multiple databases, adhering to PRISMA guidelines, yielding eight randomized controlled trials (RCTs) for inclusion. The primary outcome was wound healing assessment using the REEDA (redness, edema, ecchymosis, discharge, approximation) scale on the third, fifth and tenth postoperative days. The meta-analysis encompassed 691 primiparas. A significant difference in wound healing was observed between ST and RT on the third (I2 = 99%; Random SMD 6.75, 95% CIs 3.11-10.39, p < 0.01) and fifth days (I2 = 99%; Random SMD 3.63, 95% CIs 1.56-5.70, p < 0.01) postcaesarean section. However, no significant difference was noted on the tenth day (I2 = 5%; Random SMD 0.00, 95% CIs -0.45-0.45, p = 0.35). Sufentanil and remifentanil exhibit differential effects on early postoperative wound healing in caesarean section primiparas undergoing epidural anaesthesia. While both opioids are effective analgesics, sufentanil demonstrates a more pronounced impact on wound healing during the immediate postoperative days. Clinicians should consider these findings when selecting an opioid for pain management in this patient population.
