[Is Indian version a successful method for decreasing the incidence of breech presentation?].

In a prospective randomized study involving 30 gravidae with breech presentation the efficacy of a maternal positioning exercise--raising of the pelvis, abduction of the thighs, relaxed abdominal breathing--for the purpose of spontaneous version of the fetus into vertex presentation was investigated. The results were compared with the rate of uninfluenced, spontaneous version in a further 31 gravidae with the same initial conditions. In view of the low numbers involved no statistical statements can be made; however, version in 21 out of 30 positioned subjects (70%) as opposed to 17 out of 31 spontaneous versions indicates some degree of success. Considering the risks of breech presentation during pregnancy and at birth on the one hand and the absence of risk and good acceptance of the positioning exercise on the other, the method can be recommended.

[Effects of compression stockings on blood circulation in late pregnancy].

The effect of Class II compression stockings on maternal and fetal circulation was studied in left lateral position and standing in 21 patients with uterovascular syndrome in late pregnancy. The effect of different compression pressures was analyzed in further seven women also suffering from uterovascular syndrome in late pregnancy. It was shown that the use of compression stockings causes a measurable improvement in maternal and fetal circulation. The most favourable compression pressure for the maternal circulation parameters measured is 40 mm Hg.

[Multicenter experiences with the intracervical administration of a new PGE2 gel in labor induction].

With the participation of four Swiss obstetric clinics, medically indicated inductions of birth (with living fetuses) were performed using a new, stable PGE2 gel, and documented according to a uniform protocol. The study was conducted to investigate the efficacy of 0.5 mg of PGE2, in 2.5 ml of a vehicle (Triacetin) not yet commercially available, for local cervical maturation (n = 41). Thirty-nine patients selected by prospective randomization, in whom birth was induced conventionally, served as a control group. The efficiency of the prostaglandin gel alone or respectively with additional administration of oxytocin was evaluated on the basis of the clear changes in the cervical findings observed within 12 or respectively 24 hours, the spontaneous births, or, in the case of cesarean deliveries, according to the pelvic score. Application of PGE2 alone led to impressive changes of the cervix score and, in 34 of the 41 cases, to regular contractions after an average time of 87 minutes. After 12 hours, prior to administration of oxytocin, 43% of the patients were already delivered. The combination of locally applied PGE2 gel with conventional oxytocin induction significantly increases the number of successful inductions. The percentage of unsuccessfully attempted inductions was reduced to 24% in the PGE2 gel group as compared to 44% in the control group.

[Reaction of mother and fetus to physical stress at high altitude].

The objective of the study reported here was to investigate the reactions of mother and fetus to high-altitude hypoxia combined with physical exercise. The climb was passive, by means of scheduled journeys of the Grap Sogn Gion AG aerial cableway in Laax (Switzerland). The valley station is at an altitude of 1100 m, the mountain station at 2200 m. The mother exercised on a bicycle ergometer set to 25 watts for 3 minutes. The following were measured continuously and noninvasively: heart rate, respiratory rate, systolic and diastolic blood pressure, Po2 and Co2, uterus activity, and fetal heart rate. Twelve pregnant women with an average gestational age of 36 weeks (30th-39th week) took part in the study. Ten of the women were primiparae and two multiparae. During the trip up the mountain the barometric pressure dropped on average from 668 to 583 mmHg. This resulted in a maximum difference in Po2 between the valley and mountain stations of 18 mmHg. There were no systematic changes in Po2. Respiratory rate, heart rate, systolic and diastolic blood pressure remained unchanged during the trip up the mountain. The physical exercise at the mountain station led to an increase in respiratory rate from 12 to 20 min-1, while heart rate rose from 103 to 128 min-1, systolic blood pressure from 117 to 144 mmHg, and diastolic blood pressure from 70 to 90 mmHg. Six of the 12 women had regular contractions even during the trip up the mountain; these either remained unchanged or became less frequent in the course of the study. The mean fetal heart rate only changed slightly.(ABSTRACT TRUNCATED AT 250 WORDS)

[Pregnancy, labor and postpartum development after kidney transplantation and triple therapy with cyclosporin A--follow-up in relation to literature review].

This report pertains to a 26-year old primigravida three years after kidney transplantation and still on immunotherapy. Her pregnancy progressed without severe complications until the 33rd week of gestation. Then a sudden and rapidly worsening pre-eclampsia led to admission and delivery. The postoperative period was complicated by an episode of severe septic shock. Reported is a review of the literature. Problems following pregnancy after kidney transplantation and triple therapy including Cyclosporin A are pointed out.

[Is orthostatic circulatory regulation more difficult in multiple pregnancy? Results of a prospective longitudinal study].

In 7 multiple pregnancies the changes in maternal and fetal cardiac-circulation parameters resulting from a passive change in presentation from left lateral to steady upright were measured for the duration of pregnancy and the puerperium and compared with corresponding data from a single-fetus collective. The hypothesis that in multiple pregnancies the greater uterine contents lead to more severe problems of return flow from the lower extremities, and that these problems tend to lead a more pronounced form of uterovascular syndrome, was confirmed on the basis of the physiological data. The fact that the uterine contractions usually correlate with the maternal cyclic heart rate accelerations and peak toward the end of the third trimester of pregnancy supports the view that these contractions play a role in regulating circulation.
