Can you alteplase a port?
Using a gentle push and pull technique, alteplase is instilled into the port. A small amount (between 0.1 mL and 0.2 mL) of alteplase in the port is enough to start lysis and allow additional space for instillation of alteplase to a total dose of 2 mg (Figure 5).
How do you alteplase a line?
Using aseptic technique, clean the catheter hub with an approved antimicrobial solution. Attach a 10-ml syringe to the hub. Attempt to aspirate for a blood return. If no blood returns, connect the syringe with the alteplase and instill the alteplase into the catheter.
How do you fix a occluded PICC line?
Try flushing the catheter with 10ml 0.9% saline. If the fluids still refuse to free-flow, then instil Urokinase into the catheter and leave for 60 minutes. If this fails, repeat the Urokinase instillation but this time leave it in the line for several hours or overnight.
Can you TPA a port?
If a thrombosis is suspected, gently pulse a flush of normal saline to dislodge the clot. If the clot does not flush, the MD may order tPA (tissue plasminogen activator) to help break up the clot. To prevent clotting, a port must be flushed with normal saline daily and locked with heparin when not in use.
Is alteplase a fibrinolytic?
Alteplase is a fibrinolytic agent; it also is referred to as tissue plasminogen activator (tPA). Alteplase converts plasminogen to the proteolytic enzyme plasmin, which lyses fibrin as well as fibrinogen.
How do you reteplase an injection?
Reteplase should be administered via an IV line in which no other medication is being simultaneously injected or infused. Do not add any other medications to the injection solution.
How is alteplase administered?
Alteplase is administered intravenously at a concentration of 1 mg/mL for the treatment of acute ischemic stroke, pulmonary embolism, and myocardial infarction. The reconstituted solution is stable for 8 hours at room temperature.
Do you flush after alteplase?

What causes a PICC line to clog?
“Occlusions can be caused by a fibrin clot that blocks the lumen of the catheter. When that happens, the line can’t be used for medications or fluids; and worse, a fibrin clot can attract bacteria, making a clotted catheter a risk factor for a central line infection.”
Why would a PICC line not flush?
If you have trouble flushing a PICC, it may be occluded. Thrombotic catheter occlusions are caused by the buildup of fibrin or coagulated blood inside the PICC’s lumen or at its tip.
What is the difference between a port and a PICC line?
PICC stands for “peripherally inserted central-line catheter.” A CVC is identical to a PICC line, except it’s placed in the chest or neck. CVC stands for “central venous catheter.” A port is a catheter that’s implanted surgically under the skin on the chest.
Can port-a-cath be used for TPN?
TPN is administered into a vein, generally through a PICC (peripherally inserted central catheter) line, but can also be administered through a central line or port-a-cath.
