Brief Summary

Cesarean section is an essential surgical procedure in obstetrics, which not only addresses dystocia and certain obstetric syndromes, ensuring the safety of the maternal participants, but also increases perinatal survival rates and can save the mother's life. However, the surgical trauma and uterine contractions resulting from cesarean delivery lead to severe pain, which can hinder the mother's postoperative recovery and negatively affect her mental health. Therefore, improving postoperative pain management and addressing issues such as depression and anxiety are crucial challenges in clinical practice today. Patient-controlled intravenous analgesia (PCA) is widely used in postoperative pain management after cesarean section due to its ability to maintain the minimum effective drug concentration, minimal fluctuation in drug levels, ease of management, and no restriction on activity. However, research on the effects and adverse reactions of hydromorphone and nalbuphine for postoperative pain relief in cesarean section is limited. In this study, the investigators aim to compare the effects of hydromorphone hydrochloride and nalbuphine in obstetric PCA and examine how various clinical factors influence pain outcomes and adverse reactions. Based on multivariate analysis, the investigators further aim to construct and validate a predictive model for poor analgesic outcomes. To develop more personalized strategies for postoperative pain management following cesarean section, more personalized guidance strategies for postoperative pain management following cesarean section.

Outcome Measures

Primary Outcomes (2)

  • Incidence of pain after caesarean section

    Assessment of chronic postoperative pain by Brief Pain Inventory from 0 to ten, The higher the score, the stronger the pain

    2024-12-05-2025-05-30

  • Incidence of inadequate analgesia

    Postoperative pain is represented by NRS score (0-10). The higher the NRS score, the more severe the pain. A NRS score of ≥ 4 is considered inadequate analgesia.

    2024-12-05-2025-05-30

Secondary Outcomes (5)

  • Adverse effects of postoperative analgesia

    2024-12-05-2025-05-30

  • Usage of patient controlled analgesia (PCA)
