研究目的: |
明确择期剖宫产腰麻后产妇平卧位下预防性去氧肾上腺素(治疗产科腰麻后低血压的一线药物)的有效剂量(ED90),参考既往其他使用麻醉后左倾体位的研究,探究平卧位策略下预防用药是否存在该剂量上的差异。 |
||||||||||||||||||||||
|
Objectives of Study: |
To determine the ED90 of prophylactic phenylephrine, which is the first-line drug for treating post-anesthesia hypotension in obstetric patients, to prevent spinal anesthesia-induced hypotension during elective cesarean section in the supine position. To investigate whether the prophylactic dose alter in different position strategies, based on the previous studies that chose left tilte position after sipnal anesthesia. |
