ABSTRACT
In a prospective investigation the authors assessed the diagnostic accuracy of the biophysical profile in the detection of fetal hypoxia. They made 126 tests in 104 risk pregnancies during the 33rd-42nd week of gestation. By means of a scoring system they evaluated six biophysical parameters: non-stress test, fetal breathing movements, fetal movements, fetal tone, volume of amniotic fluid and maturity of the placenta. Ninety-six patients were delivered of a baby within seven days after the test and in these patients the course of childbirth and the condition of the fetus was evaluated. In case of a pathological biophysical score the pregnancy was terminated in 83.3% by Caesarean section, whereby the weight of the fetuses was by 48% lower (1693 g) and the height by 8 cm (41.8 cm) smaller than when the biophysical score was normal. In the detection of an adverse outcome of pregnancy, under which they included an Apgar score of 7 or less during the 5th minute, the first capillary pH less than 7.20 and perinatal death, the biophysical profile had a sensitivity of 68.8%, a specificity of 97.5%, a predictive value of the positive test of 84.6% and a predictive value of the negative test of 94%.

PIP: The analysis of intrauterine contraception studied in 2548 women during 65,925 cycles over the preiod 1974-79 revealed a total of 227 failures; i.e., in 8.9% of users and 1 pregnancy/290.4 cycles. Of this number, there were 6 extrauterine pregnancies and 11 spontaneous deliveries in women with IUDs. In 2 cases, preterm labor was recorded, and there was no incidence of fetal malformation. Failure of contraception is being evaluated with respect to age, parity, and the number of cycles followed up after IUD insertion. Influences affecting IUD frequency and its failure, as well as its potential adverse effects are discussed. (author's modified)^ieng
