I work in the Home Infusion arena and recently our agency had a patient whose PICC line severed and migrated to the right atrium. Patient was sent to the ER and had the catheter emboli removed without any further problems. When I reviewed our policy and procedure manual it states â€œUpon discovery of a severed PICC line immediately place a tourniquet on the upper arm above the IV site. Keep the tourniquet on the arm, checking to be sure the arterial circulation is not cut off.â€ Is this the latest standard? It seems to me that the best nursing practice would be to lay the patient on their left side and call 911. Can anyone share their P & P or a published article on this?
