Objective To study the pulmonary functions of pediatric ALI/ARDS(acute lung injury/acute respiratory distress syndrome) survivors. Method A prospective cohort study of all survivors of ALI/ARDS in the PICU of Beijing Children's Hospital was performed. Patients were divided into three groups(0-3 years of age,3 ~ 7 years of age, and over 7 years of age) and followed up three months after diagnosis. Results There were 36 survivors in total of 44 ALl patients, three patients lost follow-up, 12 died and 21 survived. Five survivors refused to participate in the study because of asymptomatic, and one was unable to participate because of lymphoma com-bined with sepsis. A total of 15 children completed the whole survey (11 patients were less than 3 years old, andfour were over 7 years of age). Twelve patients had no discomfort in their respiratory tracts. Three months after be-ing enrolled, the pulmonary functions of all children improved, especially in terms of tidal volume and respiratory compliance (P<0.05). Conclusions The abnormal respiratory symptoms and signs in most children disap-peared three months after discharge. Most survivors still have pulmonary dysfunction at 3 monthes after discharge, but better than discharge. 相似文献

目的探讨支气管肺泡灌洗液的Xpert MTB/RIF检测对儿童肺结核的诊断价值。方法有疑似活动性结核病的临床症状和体征,行纤维支气管镜检查并留取了支气管肺泡灌洗液的患儿为研究对象。以支气管肺泡灌洗液作为病原学检测标本,分别以病原学诊断活动性结核病和临床诊断活动性结核病为金标准,以Xpert MTB/RIF为待测标准,考察Xpert MTB/RIF对病原学和临床诊断结核的诊断价值。基于样本中结核分枝杆菌(MTB)的Ct值反映所检测样本中MTB的载量;通过对利福平耐药位点的检测,对MTB菌株进行药物敏感性检测。结果符合本文纳入标准的疑似结核病患儿351例,男198例,女153例,年龄(5.9±3.9)岁。肺结核患儿125例,其中病原学诊断结核43例(34.4%),临床诊断结核82例(65.6%);肺结核合并支气管结核51例(40.8%),单纯肺结核74例(59.2%);非结核呼吸道感染性疾病226例,肺炎支原体肺炎187例(82.7%),细菌性肺炎39例(17.3%)。Xpert MTB/RIF在病原学诊断和临床诊断结核的敏感度分别为79%(95%CI:63%~89%)和51%(95%CI:40%~62%),差异有统计学意义(χ2=9.18,P=0.002);肺结核合并支气管结核的敏感度为80%(66%~90%),单纯肺结核的敏感度47%(35%~59%);病原学诊断和临床诊断结核、合并支气管结核和单纯肺结核特异度均为100%(95% CI:97.9%~100%)。Xpert MTB/RIF检测病原学诊断结核敏感度高于临床诊断结核,肺结核合并支气管结核敏感度高于单纯肺结核,差异有统计学意义(χ2=13.88,P<0.001);支气管肺泡灌洗液的MTB核酸检出载量病原学诊断结核高于临床诊断结核,差异有统计学意义(χ2=7.37,P=0.025)。76例Xpert MTB/RIF检测阳性患儿中,利福平耐药2例(2.6%)。结论支气管肺泡灌洗液的Xpert MTB/RIF检测在儿童肺结核诊断中具有较高价值,可在缺乏细菌学诊断证据的临床诊断结核病儿童中发现MTB,具有较高的敏感度,有助于提高儿童结核病病原学检出率。 相似文献

目的初步调查北京地区2~12岁健康儿童和哮喘儿童中睡眠呼吸障碍常见症状的发生率,比较二者的差异。方法2002年6月至2003年6月间对北京6个近郊区县随机整群抽取6193例2~12岁健康儿童和北京儿童医院呼吸疾病专业门诊随机抽取的200例2~12岁缓解期哮喘儿童,由专人负责对家长进行儿童睡眠状况问卷调查。结果哮喘儿童睡眠障碍症状发生率为47·0%(94例)。其中睡眠频繁鼾症发生率为11·0%(22例),喉头哽咽1·5%(3例),张口呼吸13·0%(26例),睡眠呼吸暂停1·5%(3例),磨牙8·0%(16例),梦呓7·0%(14例),梦游0·5%(1例),睡眠中肢体抽动4·0%(8例),睡眠不安28·5%(57例)。哮喘儿童睡眠障碍发生率较无呼吸道疾病的正常儿童高,其中睡眠频繁打鼾、睡眠不安、张口呼吸和睡眠呼吸暂停的发生率差异存在显著性意义(P<0·05)。结论哮喘儿童睡眠障碍发生率高于无呼吸道疾病的正常儿童,其中睡眠频繁打鼾、睡眠不安、张口呼吸和睡眠呼吸暂停的发生率差异存在显著性意义,应引起重视。对哮喘儿童睡眠障碍的防治应进行进一步研究。 相似文献

目的探讨儿童钡剂误吸的原因及纤维支气管镜灌洗治疗的效果评估。方法研究对象为2002年2月至2006年10月在北京儿童医院被确诊为钡剂误吸14例患儿,对其进行回顾性分析,并进行追踪随访。结果①儿童钡剂误吸的发生以婴幼儿为主,新生儿期发生最多,其次为小婴儿,学龄儿少见;③吞咽功能不协调,胃、食管反流是造成钡剂误吸的主要原因;③儿童钡剂误吸的临床表现轻重程度与钡剂吸入量、发生误吸后与原发病的相互作用及治疗开始时间有关;④儿科纤维支气管镜灌洗治疗,可以有效洗出误吸钡剂。结论①儿童钡剂误吸的发生与年龄有关;②本组全部钡剂误吸儿童均为医源性;③早期、多次儿科纤维支气管镜灌洗治疗钡剂误吸有确切疗效。 相似文献

Objective To study the pulmonary functions of pediatric ALI/ARDS(acute lung injury/acute respiratory distress syndrome) survivors. Method A prospective cohort study of all survivors of ALI/ARDS in the PICU of Beijing Children's Hospital was performed. Patients were divided into three groups(0-3 years of age,3 ~ 7 years of age, and over 7 years of age) and followed up three months after diagnosis. Results There were 36 survivors in total of 44 ALl patients, three patients lost follow-up, 12 died and 21 survived. Five survivors refused to participate in the study because of asymptomatic, and one was unable to participate because of lymphoma com-bined with sepsis. A total of 15 children completed the whole survey (11 patients were less than 3 years old, andfour were over 7 years of age). Twelve patients had no discomfort in their respiratory tracts. Three months after be-ing enrolled, the pulmonary functions of all children improved, especially in terms of tidal volume and respiratory compliance (P<0.05). Conclusions The abnormal respiratory symptoms and signs in most children disap-peared three months after discharge. Most survivors still have pulmonary dysfunction at 3 monthes after discharge, but better than discharge. 相似文献
