Abstract

THE fluid in fœtal lungs has been considered to be aspirated amniotic fluid1, an ultra-filtrate of plasma or an exudate from the lungs or bronchial system2. Scattered and casual reports have appeared in the literature to the effect that, after delivery of a fœtus by Caesarean section, fluid continues to be formed in the lungs on such a scale as to suggest that the lungs may be an important source of amniotic fluid3. However, except for one instance4, no observations on the nature of the fœtal pulmonary fluid have been reported. It has been possible to collect tracheobronchial fluid during the course of experiments on mature fœtal lambs for comparison with plasma and amniotic fluid in this laboratory. The experiments were performed for a different purpose and the observations reported here are consequently limited in scope.
