根因分析

静脉铁剂（如右旋糖酐铁、羧基麦芽糖铁）具有高度刺激性，外渗后可导致严重组织坏死和永久性棕色染色；需要立即停止输液并抬高患肢。

English

IV iron preparations (e.g., iron dextran, ferric carboxymaltose) are highly irritant and can cause severe tissue necrosis and permanent brown staining if extravasated; immediate cessation and elevation are required.

解决方案

  1. 立即停止输液，断开输液管，从套管中抽吸残留铁剂，然后拔除套管。将患肢抬高至心脏水平以上。冷敷（非直接冰敷）20分钟，交替进行。拍照记录外渗情况。通知医生，考虑整形外科会诊。
  2. 对于已形成的铁外渗伴有疼痛和水疱：每日两次外用1%氢化可的松乳膏，覆盖非粘性敷料，监测皮肤破损。如出现坏死，转诊至伤口护理团队。

无效尝试

常见但无效的做法:

  1. 85% 失败

    Heat increases vasodilation and can worsen tissue damage; cold compress is preferred for iron extravasation.

  2. 92% 失败

    This increases hydrostatic pressure, forcing more iron into the interstitial space and worsening necrosis.

  3. 78% 失败

    Hyaluronidase is indicated for chemotherapy extravasation, not iron; it may spread the iron further and increase injury area.
