ABSTRACT

Se realizó un estudio descriptivo, longitudinal y prospectivo de 36 pacientes del sexo masculino con cardiopatía isquémica, intervenidos mediante cirugía correctora sin circulación extracorpórea en el Centro Territorial de Cirugía Cardiovascular de Santiago de Cuba, durante el primer cuatrimestre de 2010, a fin de identificar las modificaciones del vector de impedancia ante cambios del volumen del agua corporal por estrés quirúrgico en comparación con una población de referencia, para lo cual se utilizó el método de bioimpedancia eléctrica a 50 kHz. En la serie se apreciaron diferencias significativas en el eje mayor de las elipses de tolerancia (asociado al estado de hidratación) y en el eje menor (asociado a cambios de estructura), y la distribución del agua fue significativamente diferente entre la población de referencia y los pacientes en los estados preoperatorio y posoperatorio. Pudo concluirse que el método del análisis vectorial por bioimpedancia resulta útil para detectar las modificaciones del volumen de agua corporal provocadas por el estrés quirúrgico


A descriptive, longitudinal and prospective study of 36 patients of the male sex with ischemic heart disease was carried out. They were surgically treated by means of corrective surgery without extracorporeal circulation in the Territorial Center of Cardiovascular Surgery in Santiago de Cuba, during the first quarter of 2010, in order to identify the modifications of the impedance vector because of volume changes in body water due to surgical stress in comparison with a reference population, for which the electric bioimpedance method was used at 50 kHz. In the series significant differences in the highest axis of the tolerance ellipses were seen (associated to the hydration state) and in the smallest axis (associated to structure changes), and the distribution of water was significantly different between the reference population and the patients in the preoperative and postoperative conditions. It was concluded that the method of the vectorial analysis through bioimpedance is useful to detect the volume modifications of the body water caused by surgical stress
