The "Vidoson 635-S" high-speed ultrasonographic unit was used by the authors to examine 465 women pregnant in the second and third trimenons for the occurrence of bleeding. The following findings were obtained: NAD (no abnormality discovered), Placenta praevia totalis, Placenta praevia partialis lateralis, Placenta praevia partialis marginalis, deep adherence of placenta, early detachment of placenta, and uterus rupture. - Placental displacement was observed by repeated checking in 57 of 196 placentas with pathological findings. Placental prolapse observed between the twelfth and 20th weeks of pregnancy was defined as "early" Placenta praevia, and the birth canal was left in about 50 per cent of those cases. The authors' view about such phenomenon was that while the point of placental adherence was unchanged, some change was undergone by the uterus wall of which that part changed position to which the placenta adhered, the latter dislocation being caused by enlargement of the upper third of the passive uterus region and its part in the formation of the uterus cavity.

The emergency department is a suboptimal location for delivery, and the greater prevalence of complicated presentations and emergency deliveries results in higher morbidity and mortality. Any woman greater than 20 weeks' gestation in labor is considered medically unstable and should be triaged quickly. Fetal viability occurs after 24 to 26 weeks' gestation. Placenta previa and abruption should be considered in a woman in labor with ongoing bleeding, and ultrasound evaluation should be performed emergently. Continuous fetal monitoring is the best method to assess for heart rate variations, accelerations, or decelerations. After the fetus crowns, a finger sweep can exclude the presence of a cord prolapse or nuchal cord. Set up a safety net by notifying appropriate specialists when a complicated delivery is suspected. In shoulder dystocia, generous episiotomy, drainage of the bladder, McRobert's maneuver, and suprapubic pressure may all help disengage the anterior shoulder. With a cord prolapse, the mother is instructed not to push, and the presenting part is elevated off of the cord. Perimortum cesarean delivery is performed with gestational age greater than 24 to 26 weeks. The supine position can lead to aortocaval compression. Perimortum cesarean delivery should be performed within 4 minutes of maternal cardiopulmonary arrest.
