✦ Synopsis


Premature rupture of the membranes (PROM) accounts for approximately 30 per cent of all preterm deliveries. PROM is thought to be mainly due to a decrease in membrane integrity. The aim of our investigation was to detefmine, post-partum after 28 normal deliveries, the thickness of the amniochorionic membrane using a 20 MHz high-frequency ultrasound. The data obtained were compared with histological sections for measurement accuracy using a linear regression analysis method. The membrane thickness of the total study group was 0.83 * 0.1 1 rnm (0.72-1.08 mm). Based on a statistical comparison with the histological sections, the high-frequency ultrasound examination was shown to be highly reliable, with a correlation coefficient of ~0 . 9 6 (P<O.OoOl). High-frequency ultrasonographic examinations of membrane thickness are an objective and reliable method and may be a gain to prenatal diagnostics once this method can be used in vivo.

Premature rupture of the membranes (PROM) is still an unsolved problem in obstetrics. Neither prevention nor diagnosis nor therapy is readily available. The amniotic sac is stabilized mechanically by a dense network of collagenous fibres; in the event of PROM, the collagenous mesh is dissolved and t

It is well known that capacitance-voltage (C2V) measurements provide a simple determination of oxide thickness, but with the scaling down of components the classical method is not appropriated any more. We have observed that for two devices with the same oxide thickness and different surfaces, the c
