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.

Design outcomes

Primary

MeasureTime frameDescription
Incidence of inadequate analgesia2024-12-05-2025-05-30Postoperative 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.
Incidence of pain after caesarean section2024-12-05-2025-05-30Assessment of chronic postoperative pain by Brief Pain Inventory from 0 to ten, The higher the score, the stronger the pain

Secondary

MeasureTime frameDescription
Usage of patient controlled analgesia (PCA)2024-12-05-2025-05-30Assessment of PCA Press Count and PCA Consumption
Patient satisfaction2024-12-05-2025-05-30Assessment of patient satisfaction by score from 0 to ten, The higher the score, the more satisfied the patient.
Length of hospital stay2024-12-05-2025-05-30Assessment of the length of hospital stay
Diclofenac sodium dosage2024-12-05-2025-05-30Diclofenac sodium dosage after caesarean section
Adverse effects of postoperative analgesia2024-12-05-2025-05-30Incidence and the risk factors of adverse effects of postoperative analgesia

Other

MeasureTime frameDescription
Regression analysis of inadequate analgesia2024-12-05-2025-05-30Univariate and multivariate regression analysis of inadequate postoperative 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.
Acute postoperative pain predictive model2024-12-05-2025-05-30Development and validation of a predictive model for acute postoperative pain after cesarean section.
