“…Regarding the predictive value of the Bishop score, a meta-analysis [34] and a recently published systematic review [35] reached divergent results. Teixeira et al [34] concluded that the Bishop score still seems to be the most accurate predictive factor of vaginal delivery after IOL.…”

“…When referring to achieving the active phase of labor , either with no time limit for this to occur or within a certain time interval, the same conclusion cannot be assumed due to lack of studies assessing this outcome. On the other hand, Kolkman et al [35] showed that a Bishop score of 4, 5 or 6 was a poor predictor of IOL success if that was defined as achieving a vaginal delivery. For the prediction of cesarean delivery, the sensitivity and specificity of a Bishop score <6 was 78 and 44%, respectively, and of a Bishop score <9 was 95 and 30%.…”

Objective: The objectives of this review were to identify the predictive factors of induction of labor (IOL) failure or success as well as to highlight the current heterogeneity regarding the definition and diagnosis of failed IOL. Materials and Methods: Only studies in which the main or secondary outcome was failed IOL, defined as not entering the active phase of labor after 24 h of prostaglandin administration ± 12 h of oxytocin infusion, were included in the review. The data collected were: study design, definition of failed IOL, induction method, IOL indications, failed IOL rate, cesarean section because of failed IOL and predictors of failed IOL. Results: The database search detected 507 publications. The main reason for exclusion was that the primary or secondary outcomes were not the predetermined definition of failed IOL (not achieving active phase of labor). Finally, 7 studies were eligible. The main predictive factors identified in the review were cervical status, evaluated by the Bishop score or cervical length. Discussion: Failed IOL should be defined as the inability to achieve the active phase of labor, considering that the definition of IOL is to enter the active phase of labor. A universal definition of failed IOL is an essential requisite to analyze and obtain solid results and conclusions on this issue. An important finding of this review is that only 7 of all the studies reviewed assessed achieving the active phase of labor as a primary or secondary IOL outcome. Another conclusion is that cervical status remains the most important predictor of IOL outcome, although the value of the parameters explored up to now is limited. To find or develop predictive tools to identify those women exposed to IOL who may not reach the active phase of labor is crucial to minimize the risks and costs associated with IOL failure while opening a great opportunity for investigation. Therefore, other predictive tools should be studied in order to improve IOL outcome in terms of health and economic burden.

“…Labor may be induced with an oxytocin infusion with careful monitoring of fluid status and cardiovascular effects. 50 ST-segment depression, myocardial ischemia, arrhythmias, and even maternal deaths have been reported in association with continuous infusion and bolus dosing of oxytocin. 50 Synthetic prostaglandin analogs carry a risk of coronary vasospasm and arrhythmias.…”

Acute myocardial infarction (AMI) during pregnancy or the early postpartum period is rare, but can be devastating for both the mother and the fetus. There have been major advances in the diagnosis and treatment of acute coronary syndromes in the general population, but there is little consensus on the approach to diagnosis and treatment of pregnant women. This article reviews the literature relating to the pathophysiology of AMI in pregnant patients and the challenges in diagnosis and treatment of ST-elevation myocardial infarction (STEMI) in this unique population. From a cardiologist, maternal-fetal medicine specialist, and anesthesiologist's perspective, we provide recommendations for the diagnosis and management of STEMI occurring during pregnancy.

“…Aunque su uso está ampliamente extendido en el campo de la Obstetricia, ni el BS original ni el simplificado por Burnett han sido validados. Aunque existe una clara relación entre puntuaciones altas de estos índices y la facilidad de parto [5][6] , no está demostrado si estos pueden predecir el resultado de parto: los autores de una revisión sistemática publicada en 2013 concluyeron que el BS es un pobre predictor del resultado de parto y que es necesaria una mayor investigación en la determinación de la capacidad predictiva de los parámetros que lo forman 7 . Con este mismo argumento, Laughon y col modificaron el BS, suprimiendo los parámetros consistencia y posición 8 , pero esta simplificación, aunque validada, no consiguió mejorar de forma relevante su capacidad predictiva.…”

Fundamento. Validar la capacidad predictiva del resultado de parto de los índices Bishop (BS) y Burnett (BRS) frente a versiones modificadas en las que se incorpora la paridad (BSM y BRSM). Método.Cohortes históricas sobre un total de 728 inducciones realizadas durante los años 2011-2013 en el Hospital "La Mancha-Centro" (HLMC) de Alcázar de San Juan. Se evaluaron las características predictivas (aná-lisis de validez interna) mediante áreas bajo la curva (ABC) ROC de cada parámetro de los BS y BRS y de la paridad, así como de cada uno de los 4 índices.resultados. La paridad y todos los parámetros del BS y BRS, a excepción de la estación fetal y la posición del cuello, se asociaron con el resultado de parto. Se definieron dos nuevas escalas modificadas a partir del BS y BRS, previa eliminación del parámetro de la estación fetal, por ser el que menor capacidad discriminativa mostraba: BSM y BRSM. Se asignó un valor de 0 en las nulíparas y, en el caso de las multíparas, 3 puntos a BSM y 2 a BRSM. Los índices modificados mostraron una capacidad predictiva (ABC) de parto vaginal superior a la de los índices originales, tanto para BS (0,70 vs. 0,62) como para BRS (0,69 vs. 0,62).conclusión. Los índices modificados BSM y BRSM, donde se sustituye el parámetro altura de la presentación por la paridad, presentan mejor capacidad predictiva respecto de los índices originales BS y BRS para determinar el resultado de parto. results. Parity and all the parameters of BS and BRS, except for foetal station and cervical position, were associated with the outcome of labour. Two modified scales were defined on the basis of BS and BRS, following removal of the "foetal station" parameter due to its low discriminative capacity: BSM and BRSM. Nulliparity was given a value of 0 points, and multiparity a value of 3 points for BSM, and 2 for BRSM.Modified indices showed a higher predictive ability (AUC) for vaginal delivery than the original indices, for both BS (0.70 vs. 0.62) and for BRS (0.69 vs. 0.62).conclusion. Replacing the "foetal station" parameter with parity in BS and BRS, improves predictive capacity with regard to the original indices in order to determine the outcome of labour. Keywords

The Bishop Score as a Predictor of Labor Induction Success: A Systematic Review

Abstract: The Bishop score is a poor predictor for the outcome of induced labor at term and should not be used to decide whether to induce labor or not.
