INTRODUCCION La hipotensión arterial por anestesia raquídea en embarazadas llevadas a cesárea es frecuente y deletérea para la madre y el feto, sin que a la fecha exista una herramienta clínicamente útil para predecirla. La variabilidad de la frecuencia cardiaca es una medida que estima la actividad del sistema nervioso autónomo y algunos estudio iniciales indican una posible utilidad como herramienta predictiva de hipotensión arterial en esta población. METODOLOGIA Se realizó un estudio observacional descriptivo para examinar el comportamiento de la variabilidad de la frecuencia cardiaca, medida como razón de Baja frecuencia/Alta frecuencia, con un punto de corte de 2.5 tomada con un reloj POLAR RS800CX, en una población de pacientes con embarazo a término llevadas a cesárea, en un hospital de tercer nivel en Bogotá- Colombia entre Febrero y Abril del 2015. RESULTADOS El estudio incluyó 82 pacientes. Se determinó que la razón Baja frecuencia/Alta frecuencia mayor a 2,5 era poco frecuente en nuestra población (15.85%), y su asociación no fue significativa. DISCUSION El presente estudio demostró que la asociación entre la presencia de hipotensión y un índice Baja frecuencia/Alta frecuencia con punto de corte de 2.5 no es significativo para nuestra población de mujeres con embarazo a término llevadas a cesárea con anestesia espinal. Según los resultados se sugieres un punto de corte de 1.6 como punto de partida para la realización de nuevos estudios que permitan validar este valor. INTRODUCTION Hypotension by spinal anesthesia in pregnant women undergoing cesarean section is common and deleterious for both mother and fetus, until now there is not a clinically useful tool to predict. The heart rate variability is a measure that estimates the activity of the autonomic nervous system and some initial study indicate a possible utility as a predictive tool for low blood pressure in this population. METHODOLOGY A descriptive study was conducted to examine the behavior of the heart rate variability , measured as a ratio of Low Frequency / High frequency, with a cut of 2.5 taken with a POLAR RS800CX watch , in a population of patients with pregnancy term caesarean section carried in a tertiary hospital in Bogota Colombia between February and April 2015 RESULTS The study included 82 patients. It was determined that the reason Low frequency / high frequency greater than 2.5 was rare in our population (15.85 %) and the association was not significant. DISCUSSION The present study demonstrated that the association between the presence of hypotension and an index Low frequency / high frequency cutoff of 2.5 is not significant for our population of women with term pregnancy undergoing cesarean section with spinal anesthesia. According to the results a cutoff of 1.6 suggest as a starting point for further studies to validate this value. |
