Abstract:
Objective To wmpare the differences of the mixing time and contamination rate between liquid and powder EN preparations. Methods 20 patients,receiving enteral nutrition for more than 6 days, were enrolled in. this study. They were randomized to receive either powder enteral diet (control group, n=10) or liquid enteral diet (study group, n=10). The mixing time was examed by stopwatch. The contamination rate was determined by culture of bacteria in the solution. Results 1. The mixing time of study group was significantly shorter than that of control group ( 18.9 ± 3.0 vs 106.0 ± 21.0 , P<0. 001). 2. The bacterial culture in both groups were negative before enteral feeding. There was no positive case in study group and only 2 positive eases in control group after infusion. However, there was no statistical difference between the two groups ( P=0.14). Conclusions Liquid form of enteral nutfitent was less time cost and no ease contaminated by enveriorment, but it is expensive. he ligurd preparation has more advantages than powdor one in mixing time and comtamination.
