ABSTRACT
INTRODUCTION:
In nutrition therapy for critically ill patients, it is recommended that enteral nutrition (EN) formula be changed every 8 h to avoid bacterial contamination. However, it remains unknown whether long-term administration of EN formula from a sterile sealed bag without changing the formula can cause bacterial contamination. This study investigates the association between bacterial contamination and administration of liquid EN formula from a sterile sealed bag without changing the formula for 24 h.METHODS:
This single-center, prospective, interventional study included patients aged ≥20 years who were admitted to an intensive care unit and received 24-h continuous liquid EN formula from a sterile sealed bag. A 3-mL sample of the formula was collected from each bag every 4 h for bacterial culture. The primary outcome was the detection of bacterial colonies.RESULTS:
A total of 630 specimens from 30 patients were cultured. No bacterial colonies were detected.CONCLUSION:
There was no association between bacterial contamination and continuous administration of liquid EN formula from a sterile sealed bag for 24 h. Therefore, this study recommends continuous administration of EN from a sterile sealed bag for 24 h without changing the EN formula under those limited conditions.Palabras clave
