Sucking pattern of bottom-vented feeding bottles

Abstract

Bottle feeding is a very common type of artificial infant feeding, however certain difficulties for newborns can emerge. Sucking and swallowing can interfere with breathing for example, furthermore oxygen-saturation levels are generally lower. Therefore different types of feeding bottles exist in order to alleviate these disadvantages. The sucking pattern of a bottom-vented feeding bottle was the main subject of this study. 11 newborns were elected at the Childrens Hospital of Leoben and parents agreed for participation. A bottom-vented bottle and a conventional bottle were provided for feeding. Each newborn was fed two times and the order of the bottle was randomized. An intraoral pressure catheter was placed in the teat, furthermore O2-saturation as well as heart rate were monitored. The resulting sucking patterns were examined and evaluated. The results did not show any significant difference between the two bottles in terms of mean sucking pressure as well as mean sucking frequency. However the sucking pattern of the conventional bottle showed quick shifts in sucking pressure, which were interpreted as the opportunities to let air enter the bottle. Furthermore, vital parameters did not differ significantly, whereas the regression correlation of O2-saturation and heart rate were different. This study has shown distinctive differences among two feeding bottles in terms of the sucking pattern and shall serve as the basis for further research, concerning bottom-vented feeding bottles.
