研究目的: |
本研究主要研究目的为:评估右美托咪定鼻喷剂在剖宫产术中应用的母婴安全性:复合终点“严重不良反应发生率”(产妇:呼吸抑制/低血压/心动过缓;新生儿:1分钟Apgar≤7/气管插管/NNNS≤7);评估右美托咪定鼻喷剂在剖宫产术中应用的有效性:产妇有效性复合终点:镇静评分达标率(Ramsay≥3分)/术中追加镇静与否;新生儿有效性复合终点:首次有效吸吮时间≤1小时且24小时内哺乳次数≥8次。次要目的:评估远期影响:独立次要终点:产后抑郁评分(EPDS量表)、术中寒颤发生率、首次排气时间≤12小时、术中恶心呕吐发生率。探索性分析:心电图异常(ST段压低≥1 mm或PVCs≥5次/分钟)、脉搏氧饱变异指数(PI)异常(PI值波动幅度>40%持续>5分钟)。 |

|
Objectives of Study: |
The primary aim of this study is to evaluate the maternal and neonatal safety of intranasal dexmedetomidine spray during cesarean section: the composite endpoint of "severe adverse reaction incidence" (maternal: respiratory depression/hypotension/bradycardia; neonate: 1-minute Apgar <=7/endotracheal intubation/NNNS <=7). Additionally, the study assesses the effectiveness of intranasal dexmedetomidine spray during cesarean section: the maternal effectiveness composite endpoint: sedation score compliance rate (Ramsay >=3 points)/intraoperative supplemental sedation; neonatal effectiveness composite endpoint: first effective sucking time <=1 hour and breastfeeding frequency >=8 times within 24 hours. Secondary objectives include evaluating long-term effects: independent secondary endpoints: postpartum depression score (EPDS scale), incidence of intraoperative shivering, first flatus time <=12 hours, incidence of intraoperative nausea and vomiting. Exploratory analyses will cover ECG abnormalities (ST segment depression >=1 mm or PVCs >=5 times/minute) and abnormal pulse oximetry plethysmographic index (PI) (PI value fluctuation >40% lasting >5 minutes). |

随机方法(请说明由何人用什么方法产生随机序列): |
由研究助理人员使用计算机生成区组随机序列(区组大小4),密封信封分配。将签署研究知情同意书的,行择期剖宫产的患者分为生理盐水喷雾组(N组)、右美托咪定鼻喷雾组(D组)。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
A computer-generated block random sequence ( block size 4 ) was used by the research assistant to seal the envelope allocation. Patients who signed the informed consent of the study and underwent elective cesarean section were divided into saline spray group ( group N ) and dexmedetomidine nasal spray group ( group D ). |
