研究目的: |
目前国内外对于预测SHS的研究主要包括有创及无创监测,其中在术前结合不同体位及不同大血管容量变化来预测SHS的研究尚缺乏,因此本课题通过研究剖宫产麻醉前不同体位下下腔静脉塌陷指数、颈动脉矫正血流时间变化对剖宫产腰麻后仰卧位低血压综合征的预测作用,对剖宫产围术期药物应用、采取准确干预措施以改善母婴预后提供一定的临床参考。 |
||||||||||||||||||||||
|
Objectives of Study: |
Currently, domestic and international research on predicting SHS mainly includes invasive and non-invasive monitoring. However, studies predicting SHS by combining different preoperative positions and changes in the volume of major blood vessels are still lacking. Therefore, this study aims to investigate the predictive role of inferior vena cava collapsibility index and carotid corrected flow time changes in different positions before cesarean section anesthesia for supine hypotensive syndrome after lumbar anesthesia. The findings are expected to provide some clinical reference for perioperative drug application and accurate intervention measures to improve maternal and neonatal outcomes during cesarean sections. |
