研究目的: |
主要目的是探讨在硬膜外分娩镇痛过程中,不同给药途径(硬膜外、穿刺点局部浸润及联合应用)给予地塞米松对产后背痛发生率及严重程度的影响。次要目的是观察不同干预对产后炎症反应指标(CRP、白细胞计数)及新生儿的安全性影响(包括感染、新生儿Apgar评分及哺乳)。 |
||||||||||||||||||||||
|
Objectives of Study: |
The primary objective is to investigate the effects of administering dexamethasone via different routes (epidural, local infiltration at the puncture site, and combined application) during epidural labor analgesia on the incidence and severity of postpartum back pain. The secondary objective is to observe the impact of different interventions on postpartum inflammatory markers (CRP, white blood cell count) and neonatal safety outcomes (including infection, neonatal Apgar scores, and breastfeeding). |

随机方法(请说明由何人用什么方法产生随机序列): |
随机序列由独立统计师使用计算机生成(不参与入组、随机分配、盲法实施或随访)。本试验采用区组随机方式,分配比例为 1:1:1:1(四组),区组大小为 4,以保证各组在不同时间点的平衡性。随机序列使用R语言统计软件产生,并由统计师导出不可编辑格式(只供授权配药人员使用)。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
The randomization sequence was generated by an independent statistician using a computer (who was not involved in patient enrollment, random allocation, blinding procedures, or follow-up). This trial employed block randomization with a 1:1:1:1 allocation ratio (four groups) and block size of 4 to ensure balanced group sizes at different time points. The randomization sequence was generated using R statistical software and exported by the statistician in a non-editable format (for use exclusively by authorized dispensing personnel). |

盲法: |
受试者、实施分娩镇痛的麻醉医生、观察与随访评估人员、以及统计分析员均对分组情况保持盲态。仅配药人员(未参与随访及数据分析)知晓组别分配,用于准备相应编号的试验药物。 |
|
Blinding: |
Subjects, anesthesiologists administering labor analgesia, observers and follow-up evaluators, and statistical analysts remained blinded to group assignments. Only the medication preparers (who did not participate in follow-up or data analysis) knew the group allocations to prepare the corresponding coded trial medications. |

II. Electronic Data Capture and Management System (EDC) Data Entry and Verification 1) Data from each CRF must be entered into the EDC system within 5 working days of completion; 2) All entries shall be performed independently by two researchers (dual-entry system), with the system automatically identifying discrepancies; 3) Data managers will initiate queries for logical errors or missing items; investigators must respond within 3 working days; 4) The principal investigator must conduct final verification and provide signed confirmation prior to data lock. III. Data Security and Confidentiality 1) All subject information shall be replaced with randomized codes instead of names and shall not contain personally identifiable information; 2) EDC system accounts shall employ tiered permission controls, with access to relevant modules restricted to authorized users only; 3) Data transmission shall utilize encrypted protocols (HTTPS/SSL) to ensure security; 4) All paper CRFs and electronic data shall be centrally archived upon trial completion, with a retention period of no less than 10 years; 5) No unauthorized access or duplication of raw data is permitted except by ethics review boards, monitors, and regulatory authorities. |
