24h食管pH监测在婴儿喘息性疾病中的应用

目的探讨24 h食管pH监测在婴儿喘息性疾病中的应用。方法对74例喘息性疾病婴儿进行24 h食管pH监测,监测指标包括食管pH<4.00的次数、反流时间≥5 min的次数、最长反流时间、卧位pH<4.00的时间占总监测时间的百分比以及Biox-Ochoa评分;对所有喘息患儿按照病情分为持续性喘息组和一般喘息组,比较2组24 h食管pH监测情况;将其中有病理性胃食管反流(GER)的40例患儿随机分为治疗组和对照组。对照组给予常规抗炎、平喘治疗,治疗组在抗炎、平喘治疗基础上加用抗GER治疗。比较2组患儿住院时间和肺部啰音消失时间?峁?4例喘息性疾病患儿病理性GER发生率为54.0%。其中持续性喘息组病理性GER发生率(69.4%),显著高于一般喘息组(39.5%);持续性喘息组各项反流指标均高于一般喘息组(Pa<0.01)。治疗组患儿住院时间、肺部啰音消失时间均较对照组明显缩短,差异均有统计学意义(Pa<0.01)。所有患儿在24 h食管pH监测中未出现严重不良反应,无终止监测的发生。结论喘息性疾病患儿病理性GER发生率高,持续性喘息患儿发生率更高。伴有病理性GER的喘息患儿经抗GER治疗后效果明显。24 h食...

Application of 24-Hour Esophageal pH Monitoring in Infantile Wheezing

Objective To explore the application of 24-hour esophageal pH monitoring in infantile wheezing.Methods Twenty-four-hour esophageal pH monitoring was performed in 74 infants with wheezing and the frequencies of pH<4.00,the frequencies of refluxes lasting longer than 5 min,and the longest episode of reflux,the percentage of time of pH<4.00 at supine position,and Boix-Ochoa grade were recorded.All the infants were divided into persistent wheezing group and normal wheezing group,24-hour esophageal pH monitoring...
