休克是由各种不同原因,在疾病发展过程中所产生的病理生理变化,是一种临床综合征。产科休克是产科特有的,即与妊娠和分娩直接有关的休克。孕妇为了适应妊娠和分娩的需要,机体各系统的组织和生理功能都发生一系列的变化,尤其在分娩过程中,胎儿和胎盘的娩出所产生的很大影响,极易引起各种并发症;因而,在预防和监护产科休克中,应考虑以下的产科特点:1.妊娠晚期,全身处于弛缓状态,静脉壁的弹性下降,容易因静脉受压而引起血流障碍。2.孕期植物神经功能不稳定,尤其子宫有丰富的感受器,容易因宫腔操作牵拉或手术创伤而引起休克。3.孕妇血中凝血因子明显升高,处于明显高凝状态,容易发生弥散性血管内凝血(DIC)及静脉栓塞。4.分娩的创伤,胎盘的病理或排出时异常都可引起大量产后出血,导致失血性休克。
Shock is caused by a variety of reasons, the pathological changes in the disease development process, is a clinical syndrome. Obstetric shock is obstetrical, that is, shock directly related to pregnancy and childbirth. Pregnant women in order to meet the needs of pregnancy and childbirth, the body’s various organizational and physiological functions have undergone a series of changes, especially in the delivery process, the fetus and placenta produced by the great impact, can easily lead to various complications; Therefore, in the prevention and monitoring of obstetric shock, the following obstetric features should be considered: 1. Late pregnancy, the whole body in a state of relaxation, the elasticity of the venous wall decreased, prone to venous pressure caused by blood flow disorders. 2 during pregnancy autonomic instability, in particular, the uterus is rich in receptors, easy to pull or surgical trauma due to uterine cavity caused by shock. 3. Pregnant women blood coagulation factor was significantly elevated, in a state of significant hypercoagulability, prone to diffuse intravascular coagulation (DIC) and venous thrombosis. 4. Childbirth trauma, placental pathology or abnormal discharge can cause a large number of postpartum hemorrhage, leading to hemorrhagic shock.
