Objetivo: Evaluar la utilidad del índice cerebroplacentario fetal (ICP) para predecir resultados perinatales adversos en gestaciones de 41 semanas con trabajo de parto inducido. Material y Método: Estudio analítico, retrospectivo, observacional y transversal de pruebas diagnósticas en 97 gestantes de 41 semanas atendidas en el Hospital Regional Docente de Trujillo - Perú entre enero del 2015 a diciembre del 2018, en quienes mediante estudio Doppler se realizó el cálculo antenatal del ICP fetal y se evaluó su predicción con resultados perinatales adversos durante el trabajo de parto inducido. Resultados: Con valor umbral de 1,205, bajo la curva ROC, el ICP fetal predijo la presencia de puntuación del APGAR menor de 7 a los 5 minutos con sensibilidad del 100%, especificidad del 96,84%, con un índice de validez del 96,91% y Likelihood Ratio (LR) positivo de 31,67 (IC 95%, 10.4 - 96.43). Los valores umbral o cut- off del ICP fetal para predecir la presencia de liquido amniótico meconial y cesárea por sufrimiento fetal agudo intraparto fueron de 1,755 con LR positivo de 1,85 (IC 95%, 1,32 - 2,61) y de 1,985 con LR positivo de 1,32 (IC 95%, 0.98 - 1,78), respectivamente. Conclusión: El ICP fetal tiene utilidad para predecir la puntuación del APGAR menor de 7 a los 5 minutos, pero no predice la presencia de líquido meconial y parto por cesárea debido a sufrimiento fetal agudo en gestantes de 41 semanas con trabajo de parto inducido
Objective: Evaluate the utility of the fetal brain-placental index (BPI) to predict adverse perinatal outcomes in gestations of 41 weeks with induced labor. Material and Method: Analytical, retrospective, observational and cross-sectional study of diagnostic tests in 97 pregnant women of 41 weeks attended in the Hospital Regional Docente of Trujillo - Peru from January 2015 to December 2018, in whom the Doppler study was performed the antenatal calculation of the fetal BPI and its prediction was evaluated with adverse perinatal results during the induced labor. Results: With a threshold value of 1.205, under the ROC curve, fetal BPI predicted the presence of APGAR score of less than 7 at 5 minutes with sensitivity of 100%, specificity of 96.84%, with a validity index of 96. , 91% and Likelihood Ratio (LR) positive of 31.67 (95% CI, 10.4 - 96.43). The threshold or cut-off values of fetal BPI to predict the presence of meconium amniotic fluid and cesarean section due to acute intrapartum fetal distress were 1,755 with a positive LR of 1.85 (95% CI, 1.32-2.61) and 1,985 with positive LR of 1,32 (95% CI, 0.98 - 1.78), respectively. Conclusion: Fetal BCI is useful for predicting the APGAR score of less than 7 at 5 minutes, but does not predict the presence of meconium fluid and cesarean delivery due to acute fetal distress in pregnant women of 41 weeks with induced labor.
