PURPOSE: to evaluate the perinatal outcomes of pregnancies complicated by oligohydramnios, not due to premature rupture of membranes (PRM), diagnosed until the 26th week of gestation. PATIENTS AND METHODS: we analyzed retrospectively the cases of oligohydramnios that occurred from January 1994 to December 2000, and were diagnosed until the 26th week of gestation. Oligohydramnios was present when the amniotic fluid index was less or equal to 5.0 cm. After diagnosis the patients were followed-up with serial ultrasound evaluation, with emphasis on the maintenance of the oligohydramnios state. When remission of the oligohydramnios occurred, patients remained in the study. Cases due to PRM, fetal death detected on the first examination and the women who gave birth in another institution were excluded from the study. Concerning the patients, the presence of clinical and obstetric diseases was investigated. As regards the newborns, we evaluated birth weight, time of admission/death, occurrence of death or malformations. RESULTS: twenty-seven cases of oligohydramnios were analyzed. Thirteen fetuses had congenital anomalies, and among them, eight had anomalies of the urinary tract, four of the nervous system and one had cystic hygroma. Fourteen patients had a clinical or an obstetric disease, mainly hypertension (10 cases). In addition, we found three cases of placenta previa and one case of thyropathy. There were thirteen fetal deaths and fourteen neonatal deaths. CONCLUSION: oligohydramnios not due to PRM, occurring in the second trimester of gestation, independent of the etiology or the presence of congenital anomalies, was associated with a fatal perinatal result.

PURPOSE: to evaluate maternal and perinatal outcomes of premature rupture of membranes up to the 26th week of gestation. METHODS: retrospective analysis of the cases of premature rupture of membranes up to the 26th week of gestation, without signs of labor or treatment for this condition before admission, followed up at the Obstetric Pathology Infirmary of the "Maternidade Escola Assis Chateaubriand", Federal University of Ceará, from January 1994 to December 1999. The cases with gestational age less than 22 weeks and birth weight lower than 500 g were excluded. Premature rupture of membranes was confirmed by sterile speculum examination. In doubt, amniotic fluid crystallization test and pH determination were performed. All pregnant women underwent ultrasound examination to determine gestational age and amniotic fluid volume. Data concerning the result of gestation and consequences for the mother, fetus and neonate were analyzed. RESULTS: a total of 29 cases of premature rupture of membranes fulfilled inclusion criteria. The mean gestational age at rupture of membranes was 22 weeks. The mean duration of the latency period was 21.7 days. There Were 22 spontaneous vaginal and 3 induced deliveries, besides 4 cesarean sections. In six pregnant women there were signs of infection before labor. Antibiotics were administered in 37.9% of the cases and corticosteroids in 6.9%. No patient underwent tocolysis. There were 3 fetal and 25 neonatal deaths. Only one infant survived. This child remained at the neonatal care unit for 19 days due to infection and respiratory distress syndrome. There was no maternal death. CONCLUSION: the premature rupture of membranes up to the 26th week of gestation has been a fatal discase for fetuses and newborns in our institution.
