155例小儿肠炎阴离子间隙分析

Analysis of Children Enteritis Anion Gap in 155 Gases

目的探讨不同病原引起的小儿肠炎的阴离子间隙(AnionGap,AG)变化及其与血清电解质的关系。方法收集155例细菌性肠炎、霉菌性肠炎、病毒性肠炎治疗前的AG及血清电解质资料,比较不同病原之间的AG差异及其影响因素。结果细菌性肠炎、霉菌性肠炎、病毒性肠炎AG增高分别为52例(47.27%)、6例(60%)、19例(54.29%);AG均值分别为16.55mmol/L、19.59mmol/L、16.96mmol/L。AG水平随血清Cl-、HCO3-的降低而增高,同脱水轻重无关。结论不同感染因素引起的小儿肠炎的AG改变无差异,AG增高是小儿肠炎代酸的确切依据,是补碱的可靠指征。

Objective Studying the change of children enteritis which caused by different predominant Anion Gap （AG） and its relation with serum electrolyte. Methods Collecting the AG and its serum electrolyte date of 155 cases for bacterial enteritis, mycotic enteritis, viral enteritis before treatment, compare with the difference of AG and its effect factor in different predominant. Results The AG is increased in bacterial enteritis mycotic enteritis, viral enteritis leave each other in 52 cases, percent is 47.27%, in 6 cases, percent is 60%, in 19 cases, percent is 54.29%; the averages of AG leave each other are 16.55mmool/L, 19.59mmol/L, 16,96mmol/L,The level of AG is increased with the serum Cl^-, HCO3^- reduced, and there is not any relating with the degree of dehydration. Conclusions The change of AG in children enteritis which caused by different infection factors in not difference, the increasing of AG is the actual proof for enteritis metabolic acidosis, and it＇s reliable index for the Base supplement.
