Root Cause

Cannulating an infected AV fistula can introduce bacteria into the bloodstream, causing septic emboli, endocarditis, and life-threatening sepsis; infected access must not be used until infection is resolved.

对感染的动静脉内瘘进行穿刺可能将细菌引入血液，导致脓毒性栓塞、心内膜炎和危及生命的败血症；感染的通路在感染消除前不得使用。

Workarounds

  1. 85% success Do not cannulate the infected AV fistula. Obtain blood cultures, start empiric antibiotics (e.g., vancomycin + gentamicin) after consulting nephrology, and arrange for temporary dialysis access (e.g., tunneled catheter) if needed. Document infection and notify vascular surgery.

  2. 75% success If the fistula must be used for urgent dialysis, use a different site (e.g., contralateral arm if available) or use a temporary catheter; never cannulate through infected skin.

Dead Ends

Common approaches that don't work:

  1. 95% fail

    Alcohol disinfection cannot eliminate biofilm or deep infection; cannulation still introduces bacteria into the bloodstream.

  2. 70% fail

    Temporary catheter placement introduces its own infection risk and delays definitive treatment of the fistula infection; the fistula still needs antibiotics and possibly surgical intervention.

  3. 90% fail

    Topical antibiotics do not treat deep infection or prevent bacteremia; they may mask symptoms and delay appropriate care.
