The Logistic Regression Analysis Of The Factors Affecting The Early Enteral Nutrition Up To Goal In Critically Ill Patients

Objective To determine the major factors affecting the early enteral nutrition up to goal in critically ill patients.Methods During the past 18 months in our ICU, 192 critically ill patients who met the criteria of enrollment, were included in this study. Depending on whether enteral nutrition supply is reach to 60% nutrition goal [25kcal/(kg·d)] at the third day, the patients were divided into two groups: up to goal and not up to goal. The clinical characteristics, laboratory discoveries and kinds of interventions were compared in the two groups, and then were analysed by meams of logistic regression analysis, in order to clarify the main impact factors of early enteral nutrition up to goal.Results Gastrointestinal tract surgery,administration of catecholamine,sedation and opioid,renal dysfunction,feed intolerance,severe acute pancreatitis(SAP) and APACHEⅡscore were significantly different between the two groups (P <0.05). All of them were included in the logistic regression excepting for SAP. The results of logistic regression analysis showed that, the gastrointestinal tract surgery and catecholamine had affected early enteral nutrition up to goal (P <0.05). The OR values were 7.094(95%CI 1.841~27.332)and 3.076(95%CI 1.295~7.302)respectively.Conclusions Excepting SAP ,the main factors affecting the early enteral nutrition up to goal were the integrity of gastrointestinal tract and the hemodynamic stability.
