I have an av fistula in the antecubital space of my arm and a peritoneal dialysis catheter, is there a safe way to play paintball ?

Would avoid: High impact paintball may cause damage ask your surgeon what they think.

Paintball and access: I would consider wearing an arm and elbow pad on your upper arm and elbow that is placed in the direction to cover the fistula. As for the pd catheter -- i would either tape the catheter to your abdomen or wear some sort of girdle that secures the catheter firmly against you and doesn't leave it free to move.

Play with PD: Yes. Wear protective clothing on abdomen and on arm. If the av fistula is less than 10 weeks old, though, then wait til it matures more fully. You do not want it to clot. Be sure to secure the PD catheter with tape according to your RN instructions;
