VALLADARES HERNANDEZ, Marta del C et al. Volumetric expansion and behavior of the oligoamnios. Rev Ciencias Médicas [online]. 2009, vol.13, n.4, pp.2-13. ISSN 1561-3194.

An intervention-action, analytical and cohort research was conducted at "Abel Santamaria Cuadrado" University Hospital-2007, aimed at showing the effectiveness of maternal volumetric expansion in the increase of the amniotic-fluid volume in 28-39 weeks-pregnant women presenting oligoamnios by means of intravenous infusion with isotonic solutions. The study group was comprised of 28-39 weeks-pregnant women presenting oligoamnios, to whom volumetric expansion was indicated (n=125) and two control groups: the first comprised of pregnant women without oligoamnios and delivering in the same period (n=125); the second group of pregnant women that presented oligoamnios detected at 40 weeks or more of pregnancy and without the possibility of volumetric expansion (n=125), 375 pregnant women were in the final sample. To the statistical analysis the percentage method and the chi-square test with 95% of certainty were used. An increase was obtained in the amniotic-fluid rate (AFR), 96, 8% of the pregnant women after the third dose of treatment, the main causes to perform the cesarean section were: acute fetal distress, pelvic presentation and failed labor induction associated to a low rate of induction and preterm births with low neonatal morbidity. Concluding that; volumetric expansion is an efficient therapeutic option in the treatment of oligoamnios, extending pregnancy without increasing neonatal morbidity.
