[The prognostic importance of ultrasonic pelvimetry in anatomically contracted pelvis].

The lesser pelvis parameters measured by ultrasonic pelvimetry are characterized by different prognostic value for the functional assessment of various anatomic forms of contracted pelvis. Direct dimensions of the lesser pelvis, a difference of direct size of the orifice and fetal head biparietal size, and the pelviocranial index are prognostically the most valuable for patients with generally contracted pelvis. The same parameters are valuable for cases with Deventer's pelvis, and the sacrum flattening index value is also significant here. This latter characteristic is the only one prognostically valuable for cases with mesatipellic pelvis, permitting the prediction of possible labor complications.

[Dynamics of forward fetal movement during labor and its graphic interpretation].

The paper provides echographic++ findings of dynamics of fetal forward movement along the reproductive tract from 88 parturients. It has been found that displacement of the placenta previa was recorded by echography++ when the cervix uteri was 3'36 cm dilated and this continued in accordance with the type revealed (ascending, stepwise, or wave-like). The graphs of fetal head displacement were generally similar to those of increased dilatation of the uterine orifice. Possible biological mechanisms that regulate the coupling of the two processes during labour are also considered in the paper.

[Fetal shoulder girdle dystocia during labor].

Shoulder dystocia occurred in 98 women (0.9%) among 10,695 deliveries during the period of 1986-1988. The most frequent cause was overweight and strangulated umbilical cord. The following maneuvers were used: pressure on the uterine fundus, strong flexion of legs (maneuver of Knebel-Macroberts-Korokawa) and in 12 cases--extraction of the posterior hand. The head should be rotated to the opposite thigh of the parturient in cases with incorrect rotation of the head--the most frequent cause for low shoulder dystocia. Prophylactic measures are of special significance: cesarean section in women with large fetus, estimated by ultrasound, or with fetus with thoracic diameter larger than biparietal diameter with 1.5 sm. The delivery should be managed by the most experienced obstetricians and should not be protracted or precipitate without indications.

Fluoroscopic study of the birth posture of the sheep fetus.

Video-taped fluoroscopy was used in a research programme to review the characteristic attitudes of fetal limbs, head, neck and trunk, throughout the course of physiologically normal parturition in sheep. Nine fetuses from eight ewes were monitored during the whole process of natural birth by means of image-intensified X-ray fluoroscopy. All nine births were spontaneous and full term; with one exception they were unassisted. In all examinations the ewes were placed on their left sides on the X-ray table and lightly restrained with loose rope shackles. At parturition the ewes were fully conditioned to the examination procedure and had considerable limb mobility which allowed them to strain naturally during labour. No treatment was given to induce parturition or sedation. The consistency of observations was notable. A major finding was in the postural adaption of the forelimbs, taking the form of carpal extension with extreme flexion of the elbow and shoulder joints. This prepartum posture persisted throughout parturition in all monitored cases and is suggested as normal. The moulding effect of uterine contractions evidently acted on the hindquarters, contributing to their bunched (flexed) posture until mid-expulsion of the fetus. Full extension of all the hind limb joints occurred promptly when the fetal stifle region contacted the maternal pubis at terminal expulsion.
