因新生儿均为专性鼻呼吸者,如由各种病因造成鼻阻有可能致严重呼吸道阻塞、急性呼吸窘迫而致死,偶需急救和手术。新生儿常有鼻炎、鼻阻,但罕有严重阻塞,文献研究很少,病因不详,可能与激素、免疫功能影响有关。为阐明其可能病因因素及处理方法,对8例伴有上呼吸道阻塞的新生儿鼻炎患儿进行了回顾性研究。患儿中7例足月产,1例33周早产;6例自然娩出,2例剖腹产;男6,女2;白人6,黑人2;7例在产后6小时内出现鼻阻,1例于1周龄时就诊。全部患儿均经轴位及冠状面CT扫描确诊。就诊时6例曾行细菌学检查,4例无生长,2例分离出金黄色葡萄球菌。4例有家族特应性(atopy)史;半数伴有结膜炎;1例曾行鼻分泌物涂片及纤毛摆动检查,结果正常。全部患儿的血清Ig均正常,嗜酸性白细胞数不增高。CT片均除外先天性后 Because neonatal nasal respiration are obligatory, such as caused by a variety of causes nasal resistance may cause severe respiratory obstruction, acute respiratory distress and death, and even the need for first aid and surgery. Newborns often rhinitis, nasal resistance, but rarely serious obstruction, literature research rarely, the etiology is unknown, may be related to hormones, immune function. To clarify its possible etiological factors and treatment methods, 8 cases of neonatal rhinitis with upper airway obstruction were retrospectively studied. Seven children were born with full-term labor and one was 33 weeks of preterm labor. Six patients were delivered spontaneously and two were caesarean; 6 were male and 6 were female; 6 were blacks; 2 were nosocomial and 2 were nasal obstruction within 6 hours postpartum. 1 week old treatment. All children were diagnosed by axial and coronal CT scan. 6 cases had bacteriological examination at the time of treatment, 4 cases had no growth and 2 cases isolated Staphylococcus aureus. 4 patients had a family history of atopy; half were associated with conjunctivitis; 1 had nasopharyngeal smear and ciliary wobble examination, the result was normal. All children with normal serum Ig, eosinophils did not increase the number. CT film except after congenital
