A simple and fast ultrasonographic method of detecting enteral feeding tube placement in mechanically ventilated, critically ill patients

Abstract

Abdominal X-rays, the diagnostic method for enteral feeding tube (EFT) positioning, are a source of irradiation for the patients and carry a potential risk of adverse effects. Data related to ultrasound (US)-guided EFT placement are scarce. We evaluated 41 patients with 41 EFT insertions with guidewire in place that was maintained until US examination. US detected 38 patients with proper positioning and 3 with inadequate positioning, with a sensitivity of 97% (95% CI 84.9-99.8%) and specificity of 100% (95% CI 19.7-100%). The assessment of EFT position through abdominal US is practical and safe, associated with satisfactory diagnostic accuracy.
