RESUMO

Pregnancy in women with end-stage renal disease (ESRD) requiring chronic dialysis is a rare event. After the 90 decade, there was an increased number of cases reporting success in these pregnancies. During the period of 1999 to 2007 we studied the obstetrical and perinatal outcomes of 30 pregnancies in 27 patients on dialysis, with an average age of 30.4 ± 5.13 years (range: 18-42 years). All patients were on hemodialysis. Fifteen patients were on dialysis before pregnancy with mean time of 2.93 ± 2.05 years (range: 1-8 years) and thirteen began dialysis during pregnancy. The mean serum urea was 105.07±40.72 mg/dL (range: 21-172 mg/dL); serum creatinine was 5.73±2.23 mg/dL (range: 2.49-10.4 mg/dL). Maternal hypertension was present in 24 patients (85.7%); polyhydramnios in 11 patients (39.3%); hypotireoidism in 6 patients (21,4%); gestational diabetes in 5 patients (17.8%). The use of antihypertensive drugs was necessary in 21 patients for maternal hypertension control and erythropoietin was prescribed for 25 patients to control anemia. There were 18 cesarean sections, 10 vaginal deliveries and 2 forcipes deliveries. The mean gestational age at delivery was 33.8±3.09 weeks (range: de 27-37 weeks) and the prematurity rate was 70.6% (23 cases). The birthweight at delivery was 1839.3±647.94g (range: 530-3100 g). Neonatal complications observed in the study were: respiratory distress in 19 cases (63,3%); use of CPAP in 12 cases (40%); need of orotracheal intubation in 9 cases (30%); hyaline membrane disease in 7 cases (23.3%); bronchopulmonary dysplasia in 5 cases (16.7%); sepsis in 5 cases (16.7%); use of surfactant in 4 cases (13.3%); retinopathy of prematurity in 3 cases (10%); necrotizing enterocolitis in 1 case (3.3%); intracranial hemorrhage in 1 case (3.3%).15 newborns were small for gestational age and this was correlated with maternal serum urea >100mg/dL (p=0.035). There was one fetal demise and two neonatal deaths. The newborn survival rate was 90%, but the neonatal morbity remains high among this group of patients, mainly, due to prematurity.
