In pregnant women with cervical incompetence in whom there is also dilatation of the cervix and prolapsed membranes there are technical difficulties in performing cerclage in order to prolongate pregnancy until sufficient fetal maturity assures survival of the newborn. We describe a case of cervical incompetence with prolapsed membranes at 21 weeks of gestation, in which we caused the decrease of intrauterine pressure with drainage of amniotic fluid by amniocentesis, until reintroduction of membranes into the uterine cavity was possible. This procedure allowed traction of cervical lips and cerclage with less mechanical trauma, warranting the evolution of pregnancy for 12 weeks and fetal survival

Purpose: the repetitive use of antenatal corticosteroid therapy for acceleration of fetal lung maturation has been common in cases at risk of preterm delivery. We studied the corticosterone levels at term and the morphologic aspects in the maternal and fetal adrenal glands submitted to the effect of betamethasone in the second half of rat pregnancy in order to verify its consequences. Methods: thirty female pregnant rats were divided into three groups of ten animals each. Group I received betamethasone on the 11th, 12th, 18th and 19th day of pregnancy. Group II received distilled water on the same days (control group). Group III did not receive any drug (stress control group). All rats were sacrificed on the 20th day of pregnancy when plasma corticosterone levels of dams were assessed and the maternal and fetal adrenal glands were studied by light microscopy. Results: plasma corticosterone level of dams was lower in the group treated with betamethasone (4.8 mg/dL) when compared with the control groups (17.7 and 26.8 mg/dL). The light microscopy study revealed cytoplasmatic vacuolation in the fasciculate zone in the maternal and fetal adrenal glands, which indicates adrenal suppression. Conclusions: the antenatal repetitive and prolonged use of corticosteroids in pregnant rats for acceleration of lung fetal maturation causes maternal and fetal adrenal suppression.
