ABSTRACT

Introduction: nutrition is essential in critical patients, so gastric intolerance and its detection play an important role. Measurement of gastric residual volume (GRV) for the evaluation of gastric intolerance helps to identify intolerance to enteral nutrition (EN). It is interesting to look for a correlation between the measurement of GRV through manual aspiration and that measured by ultrasound. Objective: to evaluate the correlation between the measured gastric residual volume with the residual volume calculated by ultrasound to identify gastric intolerance in neurocritical patients with enteral feeding. Material and methods: observational, longitudinal, prospective, comparative study in the intensive care unit, an analysis is carried out for the correlation between the gastric residual volume measured with residual volume calculated by ultrasound for gastric intolerance in neurocritical patients. Results: a Pearson correlation of measured gastric residual volume with gastric residual volume calculated by ultrasound upon admission of 0.265 was obtained with a value of p = 0.137; at 24 hours a Pearson correlation of 0.818 (p ≤ 0.001) was found and at 48 hours a Pearson correlation of 0.931 was found (p ≤ 0.001). Conclusions: gastric ultrasound is an alternative to identify gastric intolerance and aspiration risk in neurocritical patients with enteral nutrition since it correlates positively and statistically significantly with gastric residual volume measured by manual aspiration.
