We report a nasogastric tube that did not possess any hole in its distal tip (Figure 1). A literature search online via PubMed, Ovid and Google indicated that no previous case of such an occurrence has been reported. A Unomedical~(TM) size 16 Fr Ryle's tube (Unomedical Australia Pty Ltd, Mona Vale, NSW) with X-ray line was inserted after anaesthetic induction in a 65-year-old male undergoing coronary artery bypass surgery. This was in keeping with our department policy regarding cardiac patients being managed postoperatively in our intensive care unit. Attempting to aspirate and inject air gave the impression that the tube was kinked, at which point it was removed then re-inserted. Again, with the same clinical tests the tube appeared blocked. On the second removal, we more closely inspected the distal portion of the tube and discovered the lack of distal hole.
