Collection of gastric secretion

  • J. H. Baron


Ideally a tube should be flexible enough to swallow but stiff enough not to curl in the stomach. It should be of wide bore for adequate drainage, but with a wall thick enough not to collapse under suction. Physiologists work with trained volunteers who swallow a large oesophageal or stomach tube. Clinicians prefer to use a smaller Levin or Ryle tube passed through the nose, because most of their tests are done on reluctant patients who find small tubes easier to tolerate; patients may not voluntarily swallow a tube by mouth, but may do so involuntarily through the nose. The Levin tube, with a pointed unweighted end, is easy to pass through the nose, even if it may curl in the stomach. The weighted Ryle tube hangs more freely in the stomach, but is bulkier to introduce.
