The retrospective comparison of feeding methods (enteral, parenteral) applied continuous veno-venous hemodiafiltration (cvvhdf) patients in adult intensive care unit

Acute renal failure (ARF) is very common in intensive care patients. According to the characteristic of intensive care, this rate is 25%. Continuous renal replacement therapy (CRRT) in critical patients allows adequate dialysis and improves fluid electrolyte imbalances without increasing hemodynamic impairment. In general, the dietary needs of patients with ARF are related to the severity of the underlying disease, the current nutritional status, and the presence of acute / chronic comorbidity in ARF itself. RRT is also added to the situation as a privileged factor affecting nutritional needs The aim of this study is to retrospectively investigate what may be the effect of feeding on patients with CVVHDF in intensive care unit, duration of stay in mechanical ventilation, rate of infections, mortality and morbidity. The files of 68 patients who underwent CVVHDF between 2010 and 2015 were retrospectively reviewed in our intensive care unit. According to feeding, two groups were formed as enteral feeding (33 patients) and parenteral (35 patients) feeding. Patients were collected from the intensive care unit until discharge or exitus. The reasons for hospitalization, hospital stay and intensive care unit stay, mortality, mechanical ventilation and duration were recorded. We investigated whether infections developed during the entire follow-up period of patients in ICU. In terms of mortality, there was no statistically significant difference between enteral feeding and parenteral feeding groups. However, in the enteral feeding group, the duration of stay in mechanical ventilator in intensive state, duration of stay in ICU, duration of tracheotomy and duration of nutrition were statistically significant. In addition, the rate of urinary system infection and companion diseases such as DM were statistically significantly higher in the enteral feeding group when compared with the groups. Enteral route is recommended firstly in feeding. Nevertheless, when we examined patients who underwent CVVHDF in our study, patients who received parenteral nutrition had lower urinary infection rates, shorter mechanical ventilation and nutritional duration. The reason for this is that the general condition of patients in the parenteral group is worse, premature mortality develops, and it is believed that the shorter duration of stay in the ICU can be attributed to the duration of stay.
