TEST FOR INTRASPINAL CATHETER PATENCY.
Catheter patency may be confirmed by observing
continuous CSF backflow through the catheter. If CSF
backflow is inadequate, patency may be tested via saline
injection detailed in the alternative technique.
ALTERNATIVE TECHNIQUE:
Insert the proximal end of the catheter into the
SNAPLOCK
™
Adaptor until the catheter bottoms out.
While maintaining the catheter position, tighten the
adaptor by squeezing the black collar toward the luer
hub until the gap between the pieces is closed.
To ensure that the connection is secure, gently tug the
catheter near the adaptor.
Attach a 10ml syringe filled with preservative free saline
and flush the catheter to test for patency.
Replace the SNAPLOCK
™
cap to prevent CSF leakage.
