To the Editor.
It has been brought to my attention that after the publication of my report, "Inadvertent Intra-arterial Injection of Penicillin: An Unseen Danger" (Pediatrics 1985;75:785-786), Wyeth made certain modifications to the Tubex syringe delivery system. Specifically, Wyeth bent back the needle so that aspirate could potentially be visualized at a certain point on the glass cartridge. This was commendable; however, almost no one knows about it. Furthermore, this spot is very hard to find even if one is looking for it.
