[Vaginal sonographic assessment of a cross section of the amniotic sac in early pregnancy].
The present study describes the results of gestation sac measurement in 237 cases in early pregnant women by the technique of transvaginal sonography. Mean distance between uterine cavity and vaginal scanner probe is the reason for early detection of the gestation ring. ⋯ The early measurement of gestation sac diameter is usefull to determine correct gestation age in case of unknown conception date. From our point of view the gestation ring diameters, obtained by transabdominal technique should not be used father more for pregnancy determination when choosing the transvaginal method.

Vitamin K is required for the synthesis of active forms of some coagulation factors. Bleeding due to low levels of the vitamin K dependent coagulation factors (classic hemorrhagic disease of the newborn) is most frequently seen in newborns with a low intake of breast milk, who are not fed supplemental formula, since transplacental transfer of vitamin K seems to be small and breast milk is relatively deficient in vitamin K. Severe bleeding due to vitamin K deficiency is also observed in 4-12 weeks old infants. ⋯ Also, the late manifestation of vitamin K deficiency has been observed virtually exclusively in infants, who had not been given vitamin K parenterally at birth. Since most newborns will be breast fed and supplemental formula feeding will not be required in most healthy full term newborns, all newborns should be given a dose of vitamin K intramuscularly immediately after birth. Whether it is safe to administer vitamin K to the mother or orally to the child requires further investigation.

Comparative Study[General anesthesia or peridural anesthesia in primary cesarean section; a comparative study].
In a prospective cooperative study of gynecologists, anaesthesiologists and pediatricians we compared the effect of continuous epidural anaesthesia (23 cases) and of general anaesthesia (24 cases) on mother and newborn. All patients were delivered in the 39. to 41. week of an uncomplicated pregnancy by primary caesarean section for breech presentation or disproportion. Nearly one third of the patients with epidural anaesthesia showed an initial transitory decrease in blood pressure- up to 25%. ⋯ The neurologic examination 15 min after delivery revealed a pathologic muscle tone in three cases after general anaesthesia and in one case after epidural anaesthesia. After 7 days all children showed a normal neurobehavior. As no severe differences between the two types of anaesthesia in the effect on mother or newborn could be seen, in uncomplicated pregnancies the choice should be left to the mother.
