Have any of you ever heard a port make crackling sounds when it was flushed?
This port is only a month old, was accessed in the OR, used for the first time that night. Crackling sounds were noticed with the first flush at home.
The port is accessed with a 1/2in 22g needle. Can we be hearing tiny air bubbles that might be making the crackling sound? You can also hear the fluid flow as you flush it. So maybe the port is just very close to the surface?
We get excellent blood return and no resistance with flushing or infusions. I've been told not to worry about the crackling. I'm still curious as to what could be causing it and if anyone else has ever heard it before in their patients.
