妊娠期高血压疾病并发肺水肿的诊治

Diagnosis and treatment of hypertension in pregnancy and respiratory dysfunction

妊娠期高血压疾病仍然是母体及围生儿死亡、致残的主要原因,其发病率占总妊娠的5%～7%。其自身的病理生理改变,如小动脉痉挛,血管内胶体渗透压降低而静水压升高,微血管通透性增加等,即便在母体没有左心衰竭的情况下亦可出现肺水肿,严重影响母体呼吸功能。纠正低氧血症,去除原发病因是治疗的关键。

Hypertensive disorders complicating preg- nancy remains a leading cause of maternal and peri- natal mortality and morbidity, and affects 5% to 7% of all pregnancies. The pathophysiologic changes associated with HDCP, such as small artery spasm, a reduction in colloid osmotic pressure while an increase in intravascular hydrostatic pressure, an increase in capillary permeability, can have a serious impact on the maternal respiratory function and lead to pulmonary edema, even if without left heart failure in the mother. Correct hypoxemia and remove the primary disease is the key to treatment.
