ABSTRACT

Introduction: Traditionally, oxygenation monitoring has been performed using indices such as PaO₂/FiO₂, which requires the determination of gasometry. The trend of minimally invasive monitoring proposes to use pulse saturation in the SpO₂/FiO₂ index for the same purpose. The SpO₂/FiO₂ index has advantages: rapid obtaining and not requiring gasometry. Rice performed the SpO₂/FiO₂ and PaO₂/FiO₂ comparison demonstrating index validation, Patrick incorporates it into the SOFA scale, Kigali shows the importance of minimally invasive monitoring with SpO₂/FiO₂ and pulmonary USG in ARDS by proposing a comparable classification with that of Berlin.
Objectives: To demonstrate that there is a correlation between SpO₂/FiO₂ vs PaO₂/FiO₂ for monitoring of oxygenation in patients with chest trauma.
Material and methods: An observational, descriptive, longitudinal, ambispective study was performed in 25 patients admitted with a diagnosis of chest trauma between January, 2016 and April, 2017, in the Intensive Care service, of which 5 patients were excluded. A statistical analysis was performed using Pearson’s bivariate correlation, and if a linear correlation was significant to determine the degree of correlation. Determination of means of age, gender, type of trauma, mechanical ventilation and death were determined. The results were analyzed with the statistical program SPSS version 21.0.
Conclusions: There is a significant linear correlation between the two indexes, a correlation that is greater than 60% from the time of admission, but it acquires the highest statistical significance with a degree of correlation up to 90% from 24 hours to the end Of the study. We therefore consider a useful and significant test to assess oxygenation in patients with chest trauma.
