为了探讨婴儿继发性乳糖不耐受 (LI)的临床诊治特点 ,以单纯母乳喂养迁延和慢性腹泻的婴儿为观察对象 ,按照诊断标准和排除标准而诊断为继发性LI 5 4例 ,占观察对象的 2 9.7%。结果表明 :诱发该病的原因常是 2～ 4个月婴儿的肠道感染 ,临床上以轻型腹泻多见 ,大便为水样稀便 ,5 4例经暂停母乳喂养均治愈。提示 :迁延及慢性腹泻的婴儿 ,有继发肠粘膜损伤病史者 ,进食乳类发生腹泻而停用含乳糖食物则腹泻消失是婴儿LI的临床特点。因此 ,对于 2～ 4月龄开始出现慢性迁延腹泻一般情况尚好的婴儿 ,可暂停母乳 1 2～ 2 4h腹泻常减轻或停止 ,有助于临床诊断继发性LI。
In order to explore the clinical diagnosis and treatment of secondary lactose intolerance (LI) in infants, we evaluated infants with prolonged and chronic diarrhea infants exclusively breastfeeding, and diagnosed secondary cases of LI 5 according to diagnostic criteria and exclusion criteria, accounting for 2 9.7% of the observed subjects. The results showed that: the cause of the disease is often 2 to 4 months of intestinal infections in infants, clinically light diarrhea more common, loose stools watery stools, 54 cases were cured by suspension of breastfeeding.
