What exactly is Cathflo (alteplase) and how is it used?
Cathflo is alteplase, a thrombolytic medicine used to restore blood flow in clogged catheters (for example, central venous lines). Administration is done by instilling the drug into the catheter lumen to dissolve the blockage.
How do you administer Cathflo into a catheter?
Cathflo is administered by the “catheter dwell” method:
- Confirm you’re treating the correct problem (a suspected occlusion) and that the catheter is being used appropriately.
- Instill Cathflo into the catheter lumen for the prescribed dwell time.
- After the dwell time, aspirate and/or flush the catheter using the appropriate line volumes and technique per your institution’s protocol.
What timing matters (dwell time and flushing)?
The key steps in administration depend on the required dwell time and the subsequent aspiration/flush. Your local order set and product instructions should specify:
- The dwell duration before attempting to restore flow
- The steps to clear residual medicine from the line after dwell
- What to do if flow does not return after the first attempt
What patient or catheter factors change how it should be given?
Administration can depend on:
- The type of catheter and lumen size
- Whether the occlusion is partial vs. suspected complete
- The patient’s clinical context (for example, bleeding risk), which can affect whether alteplase use is appropriate
What should you watch for during and after administration?
Because Cathflo is a thrombolytic, the main safety concern is bleeding or related complications. Staff typically monitor for:
- Signs of bleeding at catheter sites or elsewhere
- Catheter-related complications (pain, resistance during aspiration/flush)
- Whether patency is restored as expected
Where can I get the exact administration instructions (dose, dwell time, flush/aspiration steps)?
For the precise, step-by-step administration instructions (including dose volume and dwell time), use the official prescribing information for Cathflo and your facility’s infusion/line occlusion protocol. If you want, tell me the exact Cathflo product you have (strength, formulation) and the catheter type (e.g., PICC, port, hemodialysis catheter), and I can help map the instructions to your scenario based on the label.
