Background:
In about one-fifth of radiographs performed in neonates, no exact gastric feeding tube position can be defined.
Objectives:
To determine whether injection of air via feeding tube before taking radiographs improves radiological assessment of its position.
Methods:
In the study group (n=153), air was injected via gastric feeding tube before taking a radiograph. The tube position on radiographs was compared with a blinded control group (n=381) with no injection of air.
Results:
The definition of exact gastric tube position was possible in 95% of the study group compared with 78% in the control group (p<0.001).
Conclusion:
Injection of air before taking a radiograph significantly improves the definition of exact gastric feeding tube position in neonates.
