ABSTRACT
Objectives: To assess protein and energy intake and duration of venous-venous ECMO in critically ill patients with covid-19 Methods: We conducted a retrospective observational analysis on the intensive care units of a large tertiary private teaching Hospital. Adult patients admitted to intensive care unit (ICU) with laboratory confirmed SARS-CoV-2 (RT-PCR), cannulated on venous-venous ECMO and on exclusive enteral feeding were included. Data between march 2020 and june 2021 were collected. Weight and height data were acquired at the time of admission in ICU. Body mass index (BMI) was subsequently calculated. We obtained delivery and adequacy of nutrition data from a enteral nutrition form routinely filled out by nutritionists during hospitalization. Other data were obtained from electronic medical record. For statistical analysis of the data, we used SPSS version 13.0. Result(s): This cohort included 39 patients. 27 (69.2%) were men, mean age was 50 (+/- 12) years and 11 (28,2%) had more than 60 years. The more prevalent comorbidities were obesity in 22 (56%), hypertension in 20 (51,3%) and diabetes in 6 (15,4%) patients. The mean time on ECMO was 24.7 +/- 15.2 days. 29 patients (74%) died. Regarding nutritional support, the average protein intake was 0,9 +/- 0.4 g/kg/day and calories 13.9 +/- 5.2 cal/kg/day. No statistically significant association was observed between the nutritional intake and the duration on ECMO and clinical outcomes of patients. Conclusion(s): There was a high mortality in our cohort. Center;s inexperience may have played a role in these results, in addition to other factors. We observed a high prevalence of obesity. Neither energy nor protein intake were associated with the duration of ECMO and clinical outcomes. These results are similar to other recent observational studies where an insufficient energy and protein intake did not affected mortality or other outcomes. Our small sample and study design prevents a definitive conclusion on the subject. Thus, we propose further studies to elucidate the role of adequate nutrional strategies to improve outcomes and reabilitation of patients on ECMO.
