FIBREOPTIC FETOSCOPY FOR VISUALIZATION OF THE HUMAN FETUS IN UTERO

概要

The fetus is living in the darkness. Intrauterine visualization is now feasible by means of electronic scan ultrasonography in its black and white gray scale. This report describes, therefore, recent development of new fibreoptic endoscopy to see the fetus and surroundings directly in utero in its full color. Newborns in bath tab and extriorized fetuses immersed in water were both used for ex utero experiments. In clinical situation during labor Olympus Broncho-fibre (BF 5B) or a specially designed Machida Fibre-fetoscope was inserted into the uterus as a Bougie's maneuver under the vision of obstetric speculum. Continuous drip infusion of physiological saline through the accompanying cannula was quite imperative to get clear images. In the case of breech presentation the insertion of fetoscope was easy enough to see the fetal head of hair, fetal membranes covering the placental surface and the endometrium, and fetal structures such as fingers, nails and umbilical cord which was silver-shining and pulsating. As enabling to see thin vessels under the skin in an exterioized young fetus, fibreoptic endoscopy made it possible to see the small part in short distance but it is hard to recognize the whole body from far as we usually do in open field of air.
