Resumen
DEL BIANCO-ABREU, Elsa et al. Valor predictivo del índice de líquido amniótico en las complicaciones neonatales. Rev Obstet Ginecol Venez [online]. 2012, vol.72, n.4, pp.227-232. ISSN 0048-7732.
Objective: To determine the predictive value of amniotic fluid index in perinatal complications. Methods: One hundred and twenty patients were selected. Amniotic fluid index, perinatal complications and diagnostic accuracy was evaluated. Patients were divided according to cut-off point of amniotic fluid index (group A: amniotic fluid index less than 60 mm and group B amniotic fluid index same or higher than 60 mm). Setting: Servicio de Obstetricia y Ginecologia. Hospital Central Dr. Urquinaona. Maracaibo. Estado Zulia. Results: Patients in group A presented a longer labor and there newborns had less weight than those of patients in group B (P < 0.05). In relation to perinatal complications, the frequency of fetal distress and Apgar Score less than 6 points at minute was statically superior in patients of group A compared with those in group B (P < 0.05). The cut-off value of 60 mm for prediction of fetal distress has a sensivity of 22.2 %, specificity of 96.4%, positive predictive value of 72.3 % and negative predictive value of 74.3 %; in the prediction of Apgar score equal or less than 6 points at minute had a sensivity of 25.0 %, specificity of 96.4 %, positive predictive value of 69.2 % and negative predictive value of 74.7 %. Conclusion: Amniotic fluid index has a value for prediction of fetal distress and Apgar score.
