新生儿坏死性肺炎1例并文献复习

1 case of neonate with necrotizing pneumonia: a literature review

  • 摘要: 总结1例新生儿坏死性肺炎(NP)患儿的诊疗经验并结合文献分析,梳理该病病因、临床表现、影像学特点、诊疗要点及预后,提升临床早期识别能力,减少漏误诊与不良结局。回顾分析本院1例26天足月女婴病例,患儿因颜面肿胀伴发热入院,初诊为新生儿脓毒症,经胸部CT确诊多发肺脓肿,外周血培养与宏基因组测序(mNGS)均检出金黄色葡萄球菌,经抗感染对症治疗后痊愈,5月龄复查肺部病灶完全吸收;同时检索中外数据库发现新生儿NP以足月多见,主要致病菌为金黄色葡萄球菌,首发症状以发热、气促、咳嗽为主,多数需机械通气,少数需手术治疗,早产儿病死率偏高。新生儿NP临床罕见、症状缺乏特异性,早期完善胸部CT、血培养及mNGS病原学检查可明确诊断,规范药物治疗预后良好,多数患儿可完全痊愈。

     

    Abstract: We summarized 1 case of neonate with necrotizing pneumonia (NP), integrating a literature review to outline the causes, clinical manifestations, imaging features, diagnosis, treatment and diagnosis and prognosis of such cases so as to facilitate the early clinical identification and reduce the misdiagnosis, missed diagnosis and adverse outcomes. The case was a 26-day-old full-term female infant who was admitted to the hospital with facial swelling and fever and was initially diagnosed with neonatal sepsis. The case was confirmed with multiple lung abscesses by chest computed tomography (CT); Staphylococcus aureus was detected by both peripheral blood culture and metagenomic next-generation sequencing (mNGS). The case was cured after courses of anti-infection therapies and symptomatic treatments. The chest CT was reexamined at the age of 5 months and demonstrated that the foci were completely absorbed. The domestic and foreign databases that were searched for showed that the full-term neonates were dominant among the neonates with NP. S. aureus was the predominant species of pathogen. Fever, polypnea and cough were the major initial clinical manifestations, most of the cases needed mechanical ventilation, some cases needed surgical procedures, and the mortality rate of the premature infants was high. NP is clinically rare among the neonates, and the clinical manifestations are not specific. The early chest CT, blood culture and mNGS are crucial to the diagnosis, the standardized drug therapy may achieve favorable prognosis, and most of the neonates can be completely cured.
