There are contradictory descriptions in the literature about the methods as well as the sequence of clearing the upper respiratory tract of new-born babies. In order to clarify this problem anatomical, physiological and pathophysiological aspects of the fetal and neonatal respiratory system are described. Intrauterine asphyxia can lead to aspiration of amniotic fluid (containing meconium, squamous epithelium, lanugo hair). During delivery the fetal airway is cleared by compression of the thorax. Through suction of the mouth, throat and nose--in exactly this defined sequence--before birth of the thorax, aspiration of potentially damaging material can be prevented. The particular problem associated with meconium-steined amniotic fluid is described.
关于新生儿上呼吸道清理的方法及顺序，文献中有相互矛盾的描述。为阐明这一问题，本文描述了胎儿及新生儿呼吸系统的解剖学、生理学和病理生理学方面。宫内窒息可导致羊水（含有胎粪、鳞状上皮、胎毛）吸入。分娩过程中，通过胸部按压清理胎儿气道。在胸廓娩出前，按口、咽、鼻的精确顺序进行吸引，可防止潜在有害物质的吸入。文中还描述了与胎粪污染羊水相关的特殊问题。
