An investigation into the benefits of resiting nasoenteric feeding tubes.

Partial nasal obstruction in preterm infants increases the airway resistance. In spite of this, nasal feeding tubes are often used, if only because oral tubes are difficult to secure. A palatal appliance has been devised that maintains the position of oroenteric feeding tube(s) and is not associated with local complications. In order to assess the effects of resiting feeding tubes, two related studies were carried out. The first study, a trial, included respiratory monitoring of 29 infants on the third and/or seventh day after either the appliance and oroenteric tubes had been inserted, or, in the control group, after the nasoenteric tubes had been passed. After seven days, the infants using the palatal appliance had significantly less periodic breathing, central apnea, and movement than the control group. The second study showed that the removal of feeding tubes that had been in situ for several days reduced apnea rates and produced a significant increase in transcutaneous PO2.
