霍乱患者的主要症状是由于剧烈腹泻和呕吐,引起水及电解质丢失,迅速出现脱水和微循环障碍。霍乱肠毒素引起肠液的大量分泌,但肠道对葡萄糖的吸收能力并无改变,而葡萄糖的吸收还能增进水、钠的吸收。口服液体中电解质及浓度与血浆比较,大致是等渗的。在口服液体中葡萄糖浓度为20g/L,可达到最大量钠和水的吸收;钠的浓度为90mmol/L,可导致钠与水吸收的最佳比例;钾浓度为20mmol/L,高于血浆的浓度,有利于吸收:碳 The main symptoms of cholera patients are rapid dehydration and microcirculation disorders due to severe diarrhea and vomiting, causing loss of water and electrolytes. Cholera enterotoxin causes a lot of secretion of intestinal fluid, but the intestinal absorption of glucose has not changed, while the absorption of glucose can increase water and sodium absorption. Oral liquid electrolytes and concentrations compared with plasma, roughly isotonic. In the oral liquid glucose concentration of 20g / L, can reach the maximum amount of sodium and water absorption; sodium concentration of 90mmol / L, can lead to sodium and water absorption of the best ratio; potassium concentration of 20mmol / L, higher than the plasma The concentration is conducive to absorption: carbon
