一、重症肺炎病婴体液特点(一) 脱水酸中毒1.因病婴常有食欲甚差、饥饿、进入量少,加上有的患儿伴有恶心、呕吐、腹泻,因而导致失水与代谢性酸中毒。2.严重肺炎常伴高热、呼吸快,不显性失水明显增加。3.重症肺炎由于肺实质病变广泛,换气功能受到严重障碍,二氧化碳不能排出,故除代谢性酸中毒外,还有呼吸性酸中毒(混合性酸中毒)。这时仅凭 First, the characteristics of severe pneumonia, infant fluid (a) dehydration acidosis 1. due to sick babies often have poor appetite, hunger, less access, with some children with nausea, vomiting, diarrhea, resulting in dehydration and Metabolic acidosis. 2. Severe pneumonia often accompanied by fever, rapid breathing, non-significant loss of water significantly increased. 3. Severe pneumonia As a result of a wide range of lung parenchymal disease, ventilatory function by a serious obstacle, carbon dioxide can not be discharged, so in addition to metabolic acidosis, there are respiratory acidosis (mixed acidosis). At this moment alone
