Expansión volumétrica y comportamineto de oligoamnios / Volumetric expansion and behavior of the oligoamniosExpansión volumétrica y comportamineto de oligoamnios / Volumetric expansion and behavior of the oligoamniosCon el objetivo de demostrar la efectividad de la expansión volumétrica materna en el incremento del volumen de líquido amniótico en pacientes con tiempo de gestación de 28 a 39 semanas y oligoamnios, mediante la infusión endovenosa con soluciones isotónicas, se realizó una investigación de intervención-acción, analítica y de cohorte en el Hospital "Abel Santamaría" durante el año 2007. Se seleccionó un grupo estudio conformado por las embarazadas con tiempo de gestación de 28 a 39 semanas, con oligoamnios, a las que se les indicó expansión volumétrica (n=125) y dos grupos de control: el primero conformado por las embarazadas sin oligoamnios y que parieron en ese mismo período (n=125); el segundo, por las embarazadas con oligoamnios detectado a las 40 semanas y más de gestación y que no tuvieron posibilidad de la expansión volumétrica (n=125) y finalmente, la muestra quedó constituida por 375 gestantes. En el análisis estadístico se utilizó el porcentaje y el Ji cuadrado al 95% de certeza. Se obtuvo un incremento del índice de líquido amniótico (ILA) en el 96,8% de las gestantes posterior a 3 dosis de tratamiento, las rincipales causas de cesárea fueron: el sufrimiento fetal agudo, la presentación pelviana e inducción fallida asociado a bajo índice de inducciones y nacimientos pretérminos con morbilidad neonatal baja. Por lo que se concluye que la expansión volumétrica es una opción terapéutica eficaz en el tratamiento del oligoamnios, pues permitió prolongar el embarazo sin incremento de la morbilidad neonatal.Palabras clave: expansores del volumen de plasma, trabajo de parto inducido, cesárea; morbilidad. ABSTRACT 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. Key words: plasma volume expander, induced labor, cesarean section, morbidity.
