业已证明,妊娠高血压综合征(妊高征)基本病理变化为全身小动脉痉挛,血管阻力增加、血压增高,且与血浆一氧化氮(ＮＯ)浓度降低有关[1]。目前尚不清楚硬膜外阻滞时ＮＯ增加的原因。本文观察了硬膜外阻滞下行剖宫产的妊高征患者血浆ＮＯ的变化,旨在探讨硬膜外阻滞对妊高征患者血浆
It has been demonstrated that the basic pathological changes of pregnancy-induced hypertension (PIH) are systemic arteriolar spasms, increased vascular resistance, increased blood pressure, and decreased plasma nitric oxide (NO) concentrations [1]. It is unclear why NO increases during epidural block. This article observed the epidural block cesarean section of patients with pregnancy induced hypertension in plasma NO changes in patients with epidural block to explore the impact of plasma in patients with PIH
