答:复方乳酸钠注射液因其电解质浓度、酸碱度及渗透压都与细胞外液接近,故又称平衡液。其静脉输注有以下几个作用:(1)扩张细胞外液总量,相应地提高血管内细胞外液量——血浆量,对维持有效循环、降低血液粘稠度、增进血流速度、改善微循环、预防发生不可逆性休克,都具有重要作用;(2)补充因休克和大量出血后引起的电解质特别是钠的降低;
A: The compound sodium lactate injection due to its electrolyte concentration, pH and osmotic pressure are close to the extracellular fluid, it is also known as the balance of liquid. Its intravenous infusion has the following several functions: (1) dilate the total amount of extracellular fluid, accordingly increase the extravascular blood volume - plasma volume, to maintain an effective circulation, reduce blood viscosity, increase blood flow velocity, Improve microcirculation, prevention of irreversible shock, have an important role; (2) to supplement due to shock and a large number of bleeding caused by decreased electrolytes, especially sodium;
