本文对30例婴儿蒙被综合征(IMS)的血生化、血浆渗透压及渗差进行了观察和研究,以期为制定IMS 合理的输液提供理论依据.研究结果表明:IMS 血钠均在正常范围,或正常偏低,而血浆渗透压有增高.提示IMS 呈高渗等张(部分低张)脱水.计算渗差对病情估计有一定意义.入院时血糖高者属疾病早期,预后较好;血糖低者属疾病晚期,预后差. In this paper, we observed and studied the blood biochemistry, plasma osmotic pressure and osmolarity of 30 cases of infant’s syndrome (IMS) in order to provide a theoretical basis for establishing a reasonable IMS infusion.The results show that: IMS serum sodium are in the normal range , Or normal low, while the plasma osmolality increased, suggesting hypertonic isotonic isotonic (partial hypo) dehydration.To calculate the infiltration of the disease is of some significance to estimate the admission of high blood sugar belong to the early disease, the prognosis is good; Low blood sugar is a late disease, the prognosis is poor.
