我们自1992～1998年间共收治低钙血症患儿210例,其中并发喉痉挛5例,发病率为0.14％。总结如下。1 临床资料 本组并发喉痉挛的患儿男3例,女2例。发病季节均在1—5月份;年龄在1—6个月3例,1岁1例,1岁6个月1例;其中人工喂养4例,母乳喂养1例;血钙结果:5例均低于1.8mmol/L;原发病:肺炎2例,婴幼儿腹泻2例,营养不良1例。2 讨论2.1 诱发喉痉挛因素2.1.1 内源性 均为低血钙。2.1.2 外源性 ①电解质紊乱,如患儿腹泻时电解质紊乱及肠道钙吸收减少,引起血钙下降。②感染因素;机体遭病原体感染
We collected 210 cases of hypocalcemia in children from 1992 to 1998, including 5 cases of laryngeal spasm, the incidence was 0.14%. Summarized as follows. 1 clinical data of this group of children with laryngeal spasm in 3 males and 2 females. 1 to 6 months in age, 1 case in 1 year and 6 months in 1 year, including 4 cases of artificial feeding, 1 case of breast feeding, and the result of serum calcium: 5 cases Less than 1.8mmol / L; the primary disease: pneumonia in 2 cases, 2 cases of infantile diarrhea, malnutrition in 1 case. 2 Discussion 2.1 induced laryngospasm 2.1.1 endogenous hypocalcemia. 2.1.2 Exogenous ① electrolyte disorders, such as electrolyte imbalance in children with diarrhea and intestinal absorption of calcium decreased, causing blood calcium decreased. ② infection factors; body by pathogen infection
