人体内含量最多的物质是水,体内的水及其溶质(电解质及蛋白质等)共同构成了体液。小儿的体液含量比成年人高得多,且年龄越小含量越高,例如新生儿的体液占其体重的80%,比成年男女高出二三十个百分点。因此,小儿对水分的补充较成人有更高的需求。在炎热的夏季,由于苍蝇孳生繁殖,传播各种致病微生物,如细菌、病毒、原虫等,使感染性腹泻成为小儿在夏季的高发病。又由于夏季气温高、蒸发快,人体对水分的需求本来就比凉爽季节高,因此夏季
The most abundant substance in the human body is water. The body of water and its solutes (electrolytes and proteins, etc.) together form the body fluid. Pediatric fluid content is much higher than adults, and the younger the higher the content, such as neonatal body fluids accounted for 80% of their body weight, adult men and women than adult twenty to thirty percentage points higher. Therefore, children’s water supplements have higher needs than adults. In the hot summer season, as the flies breed, the spread of various pathogenic microorganisms such as bacteria, viruses, protozoa, etc., make infectious diarrhea in children with high incidence in summer. And because of the high summer temperatures, rapid evaporation, the body’s water demand has always been higher than the cool season, summer
