Health officials in Canada have issued a warning about the possibility of “Catheter Pinch-Off” associated with Central Vascular Access medical devices. According to a release from Health Canada, Central Vascular Access Devices are generally thought to be considered safe but reports from inside the country suggest they are not fail-safe. Central Vascular Access devices are catheters used to get regular access to the vascular system for the regular dose of drugs, taking regular samples of blood, the introduction of fluids or “parenteral nutrition solutions.”
