小儿反复呼吸道感染与胃食管返流关系的探讨

A study on recurrent respiratory infection and gastroessophageal reflux in children

目的 探讨小儿反复呼吸道感染（ＲＲＩ）与胃食管返流（ＧＥＲ） 的关系。方法 采用便携式ｐＨ 自动记录仪对３５ 例反复呼吸道感染患儿进行２４ 小时食管ｐＨ 值监测，以３０ 例健康儿为对照组。结果 ＲＲＩ组ｐＨ 值＜ ４的检出次数、返流持续时间≥５ 分钟的检出次数、最长返流持续时间、总ｐＨ＜４ 的时间占总监测时间的百分率、Ｂｏｉｘ－ Ｏｃｈｏａ 综合评分均显著大于对照组（ Ｐ＜ ０－０１） ，ＲＲＩ组胃食管返流发生率为５７－１ ％ （２０／３５），显著高于对照组（１／３０）。结论 ＲＲＩ患儿胃食管返流的发生率高，两者之间有密切关系。

Objective To study the relationship between recurrent respiratory infection(RRI)and gastroesophageal reflux(GER)in children.Methods The authors performed a 24-hour esophageal pH monitoring in 35 patients with RRI and 30 healthy chidren(control)repeatedly by ambulatory pH recording.Results In RRI group,pH<4,the number of reflux lasting for longer than 5 minutes,the duration of the longest episode,the percentage of time of pH<4 for total periods and the score of Boix-Ochoa were all greater than those of the control group(P<0\^01).The results showed that 57\^1%(20/35)of RRI group were found to have GER and significantly higher than those in controls.Conclusion That GER was common in RRI,and that there was an intimate association between the GER and RRI.monia,infant Chlamydia trachomatisognition.Result:As compared to controls,the CHI patients showed significant differences on identification,no reliable differences on recognition.Conclusion: The CHI patients were injured in explicit memory,but normal in implicit memory. closed head injury; implicit memory; explicit memory
