Pulsioximetría de pacientes en hemodiálisis, de la unidad de terapia renal – fundación cardioinfantil, análisis para establecer recomendaciones

Abstract

Introduction. A lot of patients with chronic renal failure on hemodialysis have a peripheral arteriovenous fistula (AVF) to ensure proper blood flow during hemodialysis, a variability in blood flow in the arm to the distal AVF branch ipsilateral, can affect reading pulse oximetry (SpO2) (1), therefore making it unnecessarily change the site of the shot, or make poor health personnel attending patients such decisions. That is why the main objective is to clarify whether there is variation and / or SpO2 difference between the arm and the contralateral arm AVF without FAV. Materials and methods. A correlation study of patients with FAV, functional attending hemodialysis was performed. Data collection was performed using a predesigned format that included the result of pulse oximetry and associated variables before, during and after hemodialysis. Mann Whitney, accepting significant a value of p <0.05 - the median or average of the deltas of the differences in each of the arms with T Student test statistics were compared. Results. Of a total of 40 patients, no statistically significant differences were found when comparing the median saturation between the arm fistula and arm without fistula, before, during and after dialysis, however if a statistically significant positive correlation was observed. Conclusions. A statistically significant positive correlation where there was no difference in outcome between the pulse oximetry arm and arm without FAV, so you can take the pulse oximetry in either arms found.
