The rates of spontaneous transpyloric passage of three enteral feeding tubes

The rates of spontaneous passage of a self-propelling tube, a weighted nasoenteric tube (Ross Products Division, Columbus, OH), and a new unweighted transpyloric tube (Ross Products Division) were compared. This prospective, randomized comparison of outcome was performed at five medical centers and included 129 critically ill patients. Placement was confirmed radio-logically at 6, 12, 24, 48, and 72 hours. There was no significant difference between group demographics and clinical characteristics. No significant differences in location of the tubes at any time point were found when comparing the self-propelling vs weighted tubes and self-propelling vs unweighted transpyloric tubes. A significant difference was noted in transpyloric location for the unweighted transpyloric tubes vs weighted tubes at 48 hours (58% vs 29%; p = .014) and at 72 hours (62% vs 32%; p = .011).
