已知胶体可增加和延长高张盐溶液复苏失血性休克的效果。早年右旋糖酐(DEX)是研究中最常用的胶体溶液,如今羟乙基淀粉(HES)的应用也日渐增多。本研究对上述两种物质分别加在高张氯化钠溶液中对治疗严重失血性休克的效果进行了比较。实验用32只体重为4±0.5kg的混种兔,实验前禁食12小时,经耳静脉用安定、硫喷妥钠麻醉后,置入4根导管:1)从颈静脉插至右心房;2)从股静脉插入至
Colloids are known to increase and prolong the effectiveness of hypertonic saline solution in the recovery of hemorrhagic shock. Early dextran (DEX) is the most commonly used colloidal solution in the study, and the use of hydroxyethyl starch (HES) is increasing. This study compared the effects of the above two substances in hypertonic sodium chloride solution on the treatment of severe hemorrhagic shock. 32 rabbits with a body weight of 4 ± 0.5 kg were fasted and fasted for 12 hours before the experiment. After the ear vein was anesthetized by diazepam and thiopental, four catheters were inserted: 1) insertion into the right atrium from the jugular vein ; 2) from the femoral vein to insert
