ABSTRACT

Introduction: currently, resuscitation is an essential part in the management of patients with shock, so multiple forms of monitoring have been described, either by minimally invasive hemodynamic mechanisms or by ultrasound evaluation, so it is interesting to know the relationship between each type of measurement. Objective: to know if there is a correlation between the velocity time integral of the left ventricular outflow tract (DVTI) and systolic volume variability (SVV) as predictors of volume responders. Material and methods: observational, cross-sectional comparative study in the intensive care unit, an analysis was performed to assess the relationship between VTI and SVV as volume responders in patients with shock. Results: two relationships were carried out according to the data of the EV1000 type minimally invasive device and by ultrasonography, reporting the variability of systolic volume and delta of velocity time integral correspondingly, having a spearman correlation of 0.785 (p = 0.001) as well as the cardiac output measured by EV1000 and ultrasonography having a Spearman correlation of 0.688 (p = 0.002). Conclusions: data analysed with this study allowed us to confirm the correlation between systolic volume variability and the delta velocity time integral as predictors of volume response in shock patients.
