[Intrauterine aspiration in man in the early fetal period].

A total of 220 futuses obtained as a result of spontaneous and artificial abortions, 9-28 weeks of pregnancy, were investigated. The studies showed that intrauterine aspiration could be performed already beginning with the 11th-12th week of pregnancy. Intrauterine aspiration was determined on the basis of microscopical detection in the bronchi and in alveolar ducts of particles of the amniotic fluid (amnional epithelium and maternal leucocytes from the 11th-12th week, erythrocytes--from the 13th-14th week, horny scales--from the 15th-16th week, meconium--from the 23rd-24th week) and dilatation of the bronchoalveolar lumens.
