低血容量性休克是体内或血管内大量丢失血液、血浆或体液,引起有效血容量急剧减少所致的血压降低和微循环障碍。如严重腹泻、剧烈呕吐、大量排尿或广泛烧伤时大量丢失水、盐或血浆;食管静脉曲张破裂、胃肠道溃疡引起大量内出血;肌肉挫伤、骨折、肝脾破裂引起的创伤性休克及大面积烧伤所致的血浆外渗均属低血容量性休克。治疗主要是迅速补充血容量,迅速查明病因并制止继续出血或失液,根据病情决定是否使用升压药。
目的:探讨高渗盐水对失血致低血容量性休克大鼠淋巴循环的影响。
Objective:To investigate the effect of hypertonic sodium chloride(HSC) on intestinal lymph circulation in rats with hemorrhagic shock.
Sara对机上人员大声叫喊,以盖过直升机机翼的旋转声,“他失了很多血,低血容量性休克!”
Sara shouts over the sound of the whirling chopper blades, “He’s lost a lot of blood.
方法:采用肠淋巴管引流术,在低血容量性休克大鼠模型的基础上,观察高渗盐水治疗低血容量性休克过程中肠淋巴流量及其蛋白含量的变化。
Methods:Intestinal lymph flow was collected through an intestinal lymphatic cannula, and the amount was recorded with a measurable container, and its protein content was determined by Folin′s method.
