体位性低血压是糖尿病常见的并发症.在新近发现的糖尿病患者中,体位性低血压的发生率约为15%,随着糖尿病病程的延长,该发生率也在增加.现将近几年来有关糖尿病并发体位性低血压的研究简要复习如下:1 发病机理机体在骤然站立时约有500～800ml的静脉血液淤积在外周容量血管,导致静脉回流减少,中心静脉压降低,心输出量减少.正常人通过外周及内脏血管有效的收缩,心率及心输出量的增加;肾素——血管紧张素系统对立位时有效血容量降低的调节;立位时儿茶酚胺水
Postural hypotension is a common complication of diabetes.Disclosed hypotension is found in about 15% of newly-discovered diabetic patients and is also increasing with the duration of diabetes.However, in recent years, A brief review of the study of diabetes complicated with orthostatic hypotension is as follows: 1 Pathogenesis About 500 ~ 800ml of venous blood in the sudden standing body deposition in the peripheral volume of blood vessels, resulting in reduced venous return, decreased central venous pressure, cardiac output decreased. People through the peripheral and visceral blood vessels effective contraction, heart rate and cardiac output increases; renin - angiotensin system to adjust the effective blood volume downright position; when standing catecholamines
