Do children need fasting before abdominal ultrasonography?

OBJECTIVE: The present study is aimed at comparing the quality of sonographic abdominal images obtained in fasting and non fasting children. MATERIALS AND METHODS: This is a prospective study including children aged up to 12 years sequentially evaluated by two sonographers. The images were classified according to a score as follows: 1 (non-visualized or partially visualized, inappropriate for diagnosis); 2 (sufficient for diagnosis); or 3 (excellent). Images were also classified into "diagnostic" or "non diagnostic". RESULTS: Seventy-seven patients (47 boys and 30 girls) with ages ranging between 0 and 12 years (median = 1 year) were evaluated. Fasting proved a statistically significant advantage only for evaluating the gallbladder by only one of the observers (p = 0.032). Once the images were classified into either "diagnostic" or "non diagnostic" no difference was observed between the two groups. CONCLUSION: The authors conclude that fasting did not affect significantly the quality of abdominal sonographic images in children.
