INTRODUCCIÓN: La restricción del crecimiento fetal (RCF) se define como la disminución patológica de la tasa de crecimiento fetal, generalmente asociada a insuficiencia placentaria. Se diagnostica mediante ultrasonografía obstétrica y velocimetría Doppler, pero no existe un consenso global respecto a los parámetros referenciados. OBJETIVO: Brindar una revisión actualizada de la aproximación clínica de la RCF en Chile, enfocada en el uso de la ultrasonografía Doppler como herramienta fundamental para el diagnóstico, el pronóstico y el manejo de esta patología, y realizar una comparativa con respecto a otros países. MÉTODO: Se realizó una revisión con palabras clave en las bases de datos PubMed y SciELO. RESULTADOS: Se obtuvieron 89 referencias bibliográficas, logrando una revisión de datos actualizados del uso del Doppler en la RCF tanto en el mundo como en Chile. CONCLUSIONES: La Guía Perinatal 2015 publicada en Chile carece de actualización con los conocimientos y la evidencia científica más recientes. Sin embargo, concuerda en gran parte con los lineamientos y las pautas generales de manejo de la RCF de las diferentes guías clínicas analizadas. Las discrepancias entre las guías revisadas podrían explicarse por la gran variabilidad de la evidencia de los estudios científico-clínicos, los cuales es importante unificar a través de una guía que promueva una estandarización de la atención de la RCF en el país.
INTRODUCTION: Fetal growth restriction (FGR) is the pathological decrease in the fetal growth rate generally associated with placental insufficiency. Diagnosis is made by obstetric ultrasonography and Doppler velocimetry, assessing different biometric and hemodynamic parameters. However, there is no global consensus regarding the parameters to be referenced. OBJECTIVE: To provide an updated review of the FGR clinical approach in Chile, focused on the use of Doppler ultrasonography as a fundamental tool in the diagnosis, prognosis, and management of this pathology and to compare with other countries. METHOD: A literature search was conducted in the PubMed and SciELO databases, including relevant and updated articles. RESULTS: The search included 89 bibliographic references under which it was possible to make a review of the most current data on the use of Doppler in FGR both worldwide and in Chile. CONCLUSIONS: The 2015 Perinatal Guidelines published in Chile is not updated with the latest scientific evidence and knowledge. However, it largely agrees with international guidelines for FGR management. The discrepancies between the revised guidelines could be explained due to the variability of evidence from scientific-clinical studies, which are essential to unify for standardized care of FGR in the country.

Background: CPR is emerging as an important predictor of adverse pregnancy outcome and helps in management of high risk pregnancy. Therefore we undertook the study to find the correlation of CPR with perinatal outcomes in women with hypertensive disorder complicating during third trimester.Methods: 128 patients with hypertensive disorder of pregnancy, ≥32 weeks of singleton gestation, were randomly selected during their hospital visit. They were subjected to USG Doppler study to calculate MCA/UA pulsatility index-CPR. The CPR<1 was considered abnormal and >1 as normal. These results were compared with the perinatal outcome and adverse fetal outcome.Results: The present study revealed that the incidence of adverse outcomes like Apgar score <7 (36.5%), still birth (15.9%), NICU admission (69.8%) and LBW i.e. <2500 gm (68.3%) were significantly higher in abnormal CPR than normal CPR.Conclusions: Abnormal CPR is valuable in predicting the outcome of hypertensive disorders in pregnancy. CPR is an easy procedure which can be included in the routine antenatal sonographic evaluation to predict poor perinatal outcome and to detect or recognize those fetuses at risk.
