妊高征是妊娠常见的并发症,但并发典型DIC者甚为少见。临床上仅见于重症患者(先兆子痫与子痫)、且其性质多属慢性DIC,如能早期发现,积极治疗,预后较一般产科DIC为优,故产科工作者宜保持高度警惕性,早期防治当可降低妊高征母婴病率和死亡率。发病机制妊高征患者往往全身小动脉痉挛,外周血管阻力增高,血液浓缩,血粘稠性增高,致脏器灌流量下降,这些变化在重症患者中尤为显著。血供的不足,产生小血管壁缺血缺氧,使管壁内皮细胞受损,胶原
Pregnancy-induced hypertension is a common complication of pregnancy, but complicated by typical DIC are rare. Clinically, only seen in critically ill patients (pre-eclampsia and eclampsia), and its nature is mostly chronic DIC, such as early detection, active treatment, prognosis than the average obstetric DIC is excellent, so obstetric workers should maintain a high degree of vigilance, early Prevention and treatment can reduce pregnancy-induced hypertension maternal morbidity and mortality. Pathogenesis PIH patients often systemic arteriolar spasm, peripheral vascular resistance increased, blood concentration, increased blood viscosity, organ perfusion decreased, these changes are particularly significant in critically ill patients. Lack of blood supply, resulting in small blood vessel wall ischemia and hypoxia, so that damage to the endothelial cell wall, collagen
