AI指示透析护士在动静脉内瘘有局部感染迹象(红肿、发热、脓性分泌物)时仍用于透析,忽略脓毒性栓塞风险
AI instructs a dialysis nurse to use an arteriovenous fistula for dialysis despite signs of local infection (redness, warmth, purulent drainage), ignoring risk of septic emboli
ID: medical/dialysis-access-infection
根因分析
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。
English
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.

-
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.
-
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.
无效尝试
常见但无效的做法:
-
95% 失败
Alcohol disinfection cannot eliminate biofilm or deep infection; cannulation still introduces bacteria into the bloodstream.
-
70% 失败
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.
-
90% 失败
Topical antibiotics do not treat deep infection or prevent bacteremia; they may mask symptoms and delay appropriate care.
