RESUMEN
La ecografía obstétrica se ha posicionado como un apoyo importante al control prenatal, incluso por matronas y médicos generales que controlan pacientes en atención primaria. Sin embargo, la disponibilidad de ecografía realizada por médico obstetra en el sistema público es relativamente escasa, lo que ha llevado a médicos y matronas a capacitarse en ecografía obstétrica. El objetivo de este trabajo es evaluar la utilidad de realizar ecografías obstétricas de rutina en etapas posteriores al primer trimestre, basándose en la capacidad de predicción de peso y sexo fetales. Para ello, se revisaron 1.703 ecografías obstétricas realizadas en el Hospital de Calbuco entre los años 2005 y 2008. Los resultados muestran buena capacidad para predecir sexo fetal, no así en el caso del peso fetal, donde las diferencias entre los pesos estimados y reales superan los estándares aceptados. Estos datos nos pueden ayudar a dimensionar de mejor manera los alcances de las ecografías obstétricas que realizamos a nivel primario.
ABSTRACT
Obstetric ultrasound has emerged as an important support to prenatal care, including its use by midwives and general practitioners in primary health care. However, the availability of ultrasound performed by obstetric physician in the public health system is relatively low, which has led to the training of general doctors and midwives in obstetric ultrasound. The objective of this study is to evaluate the usefulness of routine obstetric ultrasound after the first trimester, based on its predictability of fetal weight and sex. With this aim, 1703 obstetric ultrasounds performed in Calbuco Hospital between 2005 and 2008 were reviewed. The results show good capacity of predicting fetal sex, but not in the case of fetal weight, where the differences between estimated and actual weights exceed accepted standards. This data can help us to better dimension the scope of obstetric ultrasound performed at the primary health level.
