Abstract

PURPOSE
Enteral nutrition is recommended in critically ill patients. On the other hand, the recommendation of nutritional support is limited and often controversial in critically ill patients in the prone position. Therefore, this study evaluated the clinical outcomes of nutritional support in critically ill patients in the prone position.
METHODS
A retrospective evaluation of the electronic medical records was conducted, including adult patients who were in the medical intensive care unit (ICU) in the prone position in Seoul National University Bundang Hospital from May 1, 2015 to June 30, 2017. The patients' characteristics, nutritional support status while they were in the prone position, mortality in ICU and during hospitalization, ICU length of stay, mechanical ventilation days, and complications, such as ventilator associated pneumonia (VAP) and vomiting were collected.
RESULTS
In total, 100 patients were included. Of these, 12 received enteral nutrition and parenteral nutrition and 88 received only parenteral nutrition. The groups were similar in terms of age, sex, number of comorbidity, weight, PaOâ‚‚/FiOâ‚‚, hours of prone position, Simplified Acute Physiology Score II (SAPS II), Acute Physiologic and Chronic Health Evaluation II (APACHE II) score, and Sequential Organ Failure Assessment (SOFA) score. No differences were observed in ICU mortality (75.0% vs. 46.6%; P=0.065), hospital mortality (83.3% vs. 58.0%; P=0.081), ICU length of stay (22.2±14.6 vs. 18.2±21.2; P=0.128) and mechanical ventilation days (19.3±14.8 vs. 14.5±19.1; P=0.098). In addition, there were no differences in the possible complications of the prone position, such as VAP (8.3% vs. 4.5%; P=0.480) and vomiting (8.3% vs. 1.1%; P=0.227).
CONCLUSION
No significant differences in the clinical outcomes were observed. Further studies will be needed to confirm the way of nutrition support while in the prone position.
