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).
