1) The study aimed to assess if there is a correlation between the diameter of Ryle's tubes used for enteral feeding in ICU patients and the incidence of chest infections. 2) The study prospectively analyzed 20 head and spinal injury patients with Ryle's tubes, noting the tube diameter, total leukocyte count (TLC) and chest infections. 3) The results showed that patients with narrower bore 14 French Ryle's tubes had a higher rate of high TLC (>10,000), chest infiltrates and infections, though the small sample size means larger studies are needed to make definitive conclusions.
