儿童坏死性肺炎(necrotizing pneumonia,NP)是儿童社区获得性肺炎的一种严重并发症,近年来,随着儿科医生对儿童坏死性肺炎认识的加深,NP的报道也逐年升高。NP系在肺组织实变的基础上,随着疾病的进展,累及的肺组织出现液化、坏死,最终形成多发囊腔或多发空洞,临床主要依据影像学诊断。既往研究显示NP多见于... 相似文献

目的 研究儿童坏死性肺炎的早期预测指标。方法 回顾性分析43例儿童坏死性肺炎与83例大叶性肺炎的临床资料,对比两组患儿的性别、年龄、发热天数、实验室检查结果及支气管镜表现,将两组间差异有统计学意义的指标纳入多因素logistic回归分析,以了解坏死性肺炎的早期预测指标。结果 坏死性肺炎组女性患儿所占比例高于大叶性肺炎组(PPP结论 WBC升高(≥15.1×109/L)、hs-CRP升高(≥121.5mg/L)、血清LDH升高(≥353.5U/L)、支气管镜下出现痰栓堵塞需要活检钳才能清除以及肺泡灌洗液呈浑浊的米汤样,可作为儿童坏死性肺炎的早期预测指标。 相似文献

目的分析儿童肺炎支原体坏死性肺炎(MPNP)临床特征及实验室结果,寻找MPNP早期诊断指标。方法回顾分析40例MPNP及60例难治性肺炎支原体肺炎(RMPP)的临床资料,比较两组患儿的差异,并绘制ROC曲线,寻找预测MPNP发生的指标。结果 MPNP组患儿的住院时间,发热时间,合并肝损伤、胸腔积液的比例,外周血白细胞(WBC)计数,中性粒细胞比例,C反应蛋白,D-二聚体,乳酸脱氢酶均明显高于RMPP组,差异有统计学意义(P0.05)。进一步行多因素logistic回归分析显示,WBC(OR=1.35,95%CI:1.09~1.68)、发热时间(OR=1.22,95%CI:1.03~1.44)是MPNP发生的危险因素(P均0.05)。绘制WBC、发热时间预测MPNP的ROC曲线,发现WBC12.6×10~9/L、发热时间13.5天对于预测MPNP发生有较高价值(AUC=0.80、0.83,P均0.001)。结论当肺炎支原体大叶性肺炎患儿出现发热时间13.5天,WBC12.6×10~9/L时,需警惕MPNP的发生。 相似文献

儿童肺炎链球菌坏死性肺炎 总被引:1,自引:0,他引:1
肺炎链球菌是儿童呼吸道感染的常见病原菌,他所致的肺炎类型以大叶性肺炎最为典型,通常不表现为坏死性肺炎(necrotizing pneumonia,NP)。国内有关NP的研究报道很少,但这一名称在重症肺炎的有关论述中时常出现。近年儿童肺炎链球菌NP病例报道有增多趋势[1],儿科医生应予以注意。1NP的定义目前并没有明确和统一的NP定义。从病理学变化过程来看,NP与肺脓肿相同。肺脓肿是细菌感染导致的肺实质坏死性病变,形成包含液化坏死物的脓腔,有临床学者将直径<2cm的多发肺内脓腔病变定义为NP或肺坏疽(pulmonary gangrene,PG)[2]。Taussig等[3]认为… 相似文献

AIM: Clinical features and outcome of 36 patients with necrotizing pneumonia (NP) as well as 36 children with parapneumonic effusions (PPE) and 36 with severe control pneumonia (CP) were investigated. The mean age of the patients in the NP, PPE and CP groups were similar (3.8 +/- 3.3 (mean +/- SD), 4.2 +/- 3.0 and 4.2 +/- 3.0 y, respectively (p > 0.05)). The duration of symptoms at presentation were 11.9 +/- 8.5, 9.2 +/- 7.2 and 6 +/- 3.6 d, respectively (p < 0.01). The diagnosis of NP was established by computerized tomography. The mean (mean +/- SD) laboratory results in patients with NP revealed a white blood cell (WBC) count of 19,300 +/- 8700/mm3, erythrocyte sedimentation rate (ESR) of 71 +/- 22 mm/h, C-reactive protein (CRP) of 13.6 +/- 11.7 mg/dl and aspartate aminotransferase (AST) of 66 +/- 132 U/L. The values of WBC, ESR, CRP and AST in the NP group were significantly higher than those of the other groups (p < 0.001). The duration of hospitalization in the NP, PPE and CP groups was 26 +/- 9, 16 +/- 6 and 10 +/- 5 d, respectively (p < 0.001). The number of febrile days was 8 +/- 4, 4 +/- 3 and 3 +/- 3 (p < 0.001), and the duration of normalization of CRP was 14 +/- 4, 11 +/- 4 and 7 +/- 3 d (p < 0.001), respectively. The average cost of treatment was 3476 US dollars, 1646 US dollars and 844 US dollars, respectively (p < 0.001). CONCLUSION: All NP patients except two (94%) were complicated with PPE. The effusion in patients with NP and PPE was complicated with bronchopleural fistula (55% and 0%, respectively, p < 0.001). Surgical treatment was required in 66%, 8% and 0% in patients with NP, PPE and CP, respectively (p < 0.001). The mortality rate was 5.5%, 2.7% and 0% (p > 0.05). 相似文献

??Objective??To evaluate the diagnostic and therapeutic value of flexible bronchoscopy in children with necrotizing pneumonia. Methods??Clinical data of children diagnosed with necrotizing pneumonia in the Department of Pediatrics of the First Hospital of Jilin University from December 2016 to December 2017 were collected. The general clinical manifestations??laboratory examination results??chest X-ray or lung CT??flexible bronchoscope and other examinations of all the children were analyzed retrospectively. Based on the characteristics??diagnosis??treatment and prognosis??the advantages of flexible bronchoscopy in this disease were analyzed. Results??All the 32 cases were diagnosed as necrotizing pneumonia by imaging examination??with an average diagnosis time of 14.1 d. All 32 cases of children with necrotizing pneumonia received flexible bronchoscopy and alveolar lavage. The alveolar lavage in 32 cases presented turbidity mitota-like changes??which had high sensitivity in the diagnosis of necrotizing pneumonia. The average time for mitota-like changes in alveolar lavage was 6.7 days. Conclusion??Flexible bronchoscopy is an important method in the diagnosis and treatment of necrotizing pneumonia??and the change of alveolar lavage fluid is a sensitive index for early prediction of necrotizing pneumonia. 相似文献

??Bacterial pneumonia is the main cause of severe pneumonia in children. It is difficult to collect the samples of children’s respiratory tract infection??especially the acquisition of lower respiratory tract specimens is a challenge for the primary pediatricians??and it also affects the etiological diagnosis of children’s respiratory tract infection. Among children under 5??bacterial pathogens include Streptococcus pneumoniae??Staphylococcus aureus and Streptococcus pyogenes. Streptococcus pneumoniae infection is more common in healthy children aged 5 and above. The etiology of bacterial pneumonia in children was reviewed in this paper. 相似文献

Aim: To identify risk factors for children developing and being hospitalised with community‐acquired pneumonia. Methods: Children <5 years old residing in urban Auckland, New Zealand were enrolled from 2002 to 2004. To assess the risk of developing pneumonia, children hospitalised with pneumonia (n= 289) plus children with pneumonia discharged from the Emergency Department (n= 139) were compared with a random community sample of children without pneumonia (n= 351). To assess risk of hospitalisation, children hospitalised with pneumonia were compared with the children discharged from the Emergency Department. Adjusted odds ratio (OR) with 95% confidence intervals (CIs) were used to estimate the risk of pneumonia and hospitalisation with pneumonia. Results: After adjustment for season, age and ethnicity there was an increased risk of pneumonia associated with lower weight for height (OR 1.28, 95% CI 1.10–1.51), spending less time outside (1.96, 1.11–3.47), previous chest infections (2.31, 1.55–3.43) and mould in the child's bedroom (1.93, 1.24–3.02). There was an increased risk of pneumonia hospitalisation associated with maternal history of pneumonia (4.03, 1.25–16.18), living in a more crowded household (2.87, 1.33–6.41) and one with cigarette smokers (1.99, 1.05–3.81), and mould in the child's bedroom (2.39, 1.25–4.72). Conclusions: Lower quality living environments increase the risk of pneumonia and hospitalisation with pneumonia in New Zealand. Poorer nutritional status may also increase the risk of pneumonia. Improving housing quality, decreased cigarette smoke exposure and early childhood nutrition may reduce pneumonia disease burden in New Zealand. 相似文献
