研究目的:

术前超声测量颈总动脉血流时间,计算颈总动脉校正血流时间(Corrected flow time,FTc)判断拟行剖宫产术产妇的容量反应性,采取个性化的预防措施,预防性胶体负荷或预防性输注去甲肾上腺素(Noradrenaline,NE),探讨预防剖宫产产妇腰麻后低血压发生的最适预防措施;同时,观察两种预防措施对新生儿结局和母体结局的影响,进一步提高母婴围术期的安全性。  

Objectives of Study:

We measured the carotid artery flow time by ultrasound before surgery, calculated the corrected flow time (FTc) of the carotid artery to determine the volume responsiveness in patients undergoing cesarean section, and took individualized prophylaxis measures, prophylactic colloidal expansion or prophylactic norepinephrine infusion, to explore the most appropriate preventive measures to prevent hypotension after spinal anesthesia in women undergoing cesarean section; meanwhile, we observed the effects of both prophylaxis measures on the neonatal outcome and maternal outcome to further improve the safety of maternal and infant during the perioperative period.
