Port-A-Cath
Points of Emphasis
- When accessing the port use only a non-coring needle. These needles have a deflected point and side opening which prevents septum coring
- When accessing the port ensure that the needle is inserted through the septum to the bottom of the port. This avoids injection into the subcutaneous tissue
- Once the septum is punctured, DO NOT rock or tilt the needle as this may damage the septum or cause fluid to leak into the subcutaneous tissue
- Ensure patency is confirmed prior to commencing any infusions
- When checking patency, discard any aspirated blood because reinsertion potentiates clot formation
- Use positive pressure to “lock-up” the system. This technique is absolutely essential in maintaining catheter patency because it prevents reflux of blood into the tip of the catheter where it could form a clot
- When accessing the Port-A-Cath, use only a non-coring needle with an attached clamped and capped extension set, which has all been primed. This will reduce the risk of air embolism and facilitate easier manipulation of the port.
- When administering fluid into the Port-A-Cath, do not use a syringe smaller than 10mL. The smaller the syringe the greater the pressure generated. Pressures greater than 40 PSI may cause catheter rupture and possible embolization
