儿童反复呼吸道感染相关因素的临床分析

Clinical analysis of influencing factors for recurrent respiratory tract infections in children

目的探讨小儿反复呼吸道感染的相关影响因素,为该病的预防和治疗提供参考依据。方法选取2009年2月-2012年7月医院收治的呼吸道感染患儿共521例,其中反复呼吸道感染患儿165例,设为观察组,同时选取普通呼吸道感染患儿356例,设为对照组;患儿治疗期间进行详细的病例记录,并通过病例资料对感染因素进行总结分析。结果早产儿、非母乳喂养及剖宫产儿童反复呼吸道感染的发生率较高;观察组血清铁、钙及锌含量分别为(12.51±3.26)、(2.12±0.52)、(19.3±14.26)μmol/L,对照组患儿分别为(16.25±6.57)、(2.54±0.63)、(31.02±19.27)μmol/L,两组比较差异有统计学意义(P<0.05)。结论对于反复呼吸道感染患儿的预防和治疗要注意血清铁、钙、锌等微量元素的补给,同时尽量进行母乳喂养。

OBJECTIVE To explore the related influencing factors for recurrent respiratory tract infections in chil-dren so as to provide guidance for prevention and treatment of the disease .METHODS A total of 521 children with respiratory tract infections who were treated in the hospital from Feb 2009 to Jul 2012 were enrolled in the study , among which 165 children with recurrent respiratory tract infections were assigned as the observation group ,356 children with common respiratory tract infections as the control group ,then the medical records were recorded in detail during the treatment ,and the risk factors for infections were analyzed through the study of the medical re-cords .RESULTS The incidence of recurrent respiratory tract infections was relatively high in the preterm children , non-breastfed children ,and caesarean children .The serum iron content was （12 .51 ± 3 .26）μmol/L in the obser-vation group ,（16 .25 ± 6 .57）μmol/L in the control group ;the serum calcium content was （2 .12 ± 0 .52）μmol/L in the observation group ,（2 .54 ± 0 .63）μmol/L in the control group ;the serum zinc content was （19 .3 ± 14 .26）μmol/L in the observation group ,（31 .02 ± 19 .27）μmol/L in the control group ,and there were significant differ-ences between the two groups （P〈0 .05） .CONCLUSION For the prevention and treatment of recurrent respiratory tract infections in the children ,attention should be paid to the supplement of serum iron ,calcium ,and zinc ,and breastfeeding should be given as much as possible .
