肺出血关键是早期诊断,等到出现口鼻或气管内向外涌血(外显性出血)则为时已晚,死亡率甚高。气道内积血是肺出血唯一具有较高特异性的客观指标,对可疑病例进行气管内吸引,能尽早发现气道内的血液,达到早期诊断,减少漏诊的目的。我们于1993年3月至1998年7月共实施21例,旨在探讨气管内吸引法在新生儿肺出血诊断中的价值,现总结如下。 Pulmonary hemorrhage is the key to early diagnosis, until the emergence of oral or intratympanic blood (overt bleeding) is too late, the mortality rate is very high. Airway hemorrhage is the only objective indicator of pulmonary hemorrhage with high specificity, the suspicious cases of endotracheal suction, as early as possible to find the blood within the airway to achieve early diagnosis and reduce the purpose of missed diagnosis. We carried out 21 cases from March 1993 to July 1998 to investigate the value of endotracheal suction method in the diagnosis of neonatal pulmonary hemorrhage, are summarized as follows.
