Correlation Analysis Of Critical Illness Scores And Tolerance Of Enteral Nutrition In Critical Patients

Objective: To observe the correlation between critical illness scores and enteral nutrition tolerance in critical patients.Methods: The design of the study was observational and retrospective.Patients receiving enteral nutrition in the department of intensive care unit of the First Affiliated Hospital of Chongqing Medical University from June2017 to June 2018 were studied.Data of 116 cases were collected to assess the tolerance of enteral nutrition and critical illness scores.Results: The Leukocyte count and body mass index in the tolerance group were lower than those in the intolerance group.The early enteral nutrition group was associated with a better tolerance of enteral nutrition in the patients of groups of APACHEII sores lower than 20,SAPSII sores lower than 40 and SOFA sores lower than 8.The APACHE II and SOFA scores at the beginning of EN were lower than those at the admission to the ICU in the tolerance group.In the EN intolerance group,the APACHE II scores decreased gradually upon admission to the ICU,the onset of EN,and the occurrence of EN intolerance.The patients in different groups weresimilar for age,ICU length of stay,duration of ventilator dependence,the time to start EN,mortality,EN dosage form,EN route,APACHEII,SAPS II,SOFA sore at admission,at beginning of EN,and the differences between two time points.Conclusion: The scores of APACHEII,SOFA,SAPS Ⅱ at admission of critically ill patients have no significant correlation with EN tolerance.The evaluation of tolerance of EN still needs comprehensive clinical evaluation.In patients with relatively mild disease,early initiation of enteral nutrition does not increase the risk of enteral nutritional intolerance.Higher leukocyte count and body mass index means higher risk of EN intolerance.Once EN was initiated,APACHE II scores declined regardless of the tolerance.
