妊娠生理病理变化使孕妇对氧和血液的需要量大增,加之血液动力学及心血管的变化,均使心脏负担加重,这对器质性心脏病患者可造成严重的后果.我院1980年1月至1989年12月,在225例器质性心脏病分娩患者中,先天性心脏病占第一位(54.6％).孕32～34周、分娩期及产后早期是发生心力衰竭的高危期.分娩期的血液动力学的改变急剧,因此对心脏病人产时的监护与处理极为重要.一、分娩期心血管系统的主要病理生理变化
Physiological and pathological changes in pregnancy so that pregnant women on the oxygen and blood demand increased significantly, coupled with changes in hemodynamics and cardiovascular, all make the heart burden, which can have serious consequences for patients with organic heart disease. From January to December 1989, congenital heart disease accounted for the first place (54.6%) in 225 patients with organic heart disease, and 32 to 34 weeks of gestation, and high risk of heart failure during labor and early postnatal period Period of delivery hemodynamic changes rapidly, so the heart of patients during childbirth guardianship and handling is extremely important. First, the main pathophysiology of childbirth cardiovascular system changes
