ABSTRACT
Objective:To analyze the failure rate of enteral nutrition feeding in patients with mechanical ventilation, explore the influencing factors, and find out the existing problems and deficiencies in the process of nutrition support.Methods:Patients who were admitted to the ICU of Zhejiang People′s Hospital from June 2020 to January 2022 for mechanical ventilation and continuous enteral nutrition through the nose were retrospectively collected as the research subjects. The patients were divided into a standard group and a substandard group. Comparing the feeding status of enteral nutrition patients in the two groups on the 7th day, Logistic regression was used to analyze the influencing factors of feeding substandard.Results:A total of 82 patients (57.34%, 82/143) had feeding failure. Logistic regression analysis showed that complications ( OR=34.47, 95% CI 9.49 to 125.21) and infusion speed ( OR=0.21, 95% CI 0.08 to 0.57) were the influencing factors of feeding failure in ICU mechanical ventilation patients ( P<0.05). Conclusions:The feeding failure rate of ICU mechanical ventilation patients is higher than the feeding failure rate, and the slow infusion speed caused by complications and feeding intolerance is the main reason for the failure. It is suggested to set personalized feeding program for patients, optimize feeding measures, and improve the feeding failure rate.
