每天摸一下廔管：震顫消失要立即處理
Check your dialysis access daily: An absent thrill needs urgent attention
中文版
每天用手輕輕摸一下廔管，是很簡單也很重要的習慣。正常的廔管通常會有持續、柔和的震顫；如果震顫明顯變弱、變得斷斷續續，或完全摸不到，可能代表血管變窄或出現血栓。
- 震顫消失
- 手臂明顯腫脹
- 拔針後出血時間延長
- 手指冰冷、疼痛或變色
- 廔管紅腫、疼痛或合併發燒
1.每天怎麼摸？
- 用指腹輕放在廔管上，不用大力壓。
- 記住平常震顫的強度與範圍。
- 如果比平常弱、斷斷續續或完全消失，要提高警覺。
2.哪些情況不要等？
- 震顫完全消失。
- 手臂突然明顯腫脹。
- 手指冰冷、疼痛或變色。
- 廔管紅腫疼痛，或同時發燒。
💡 廔管狀況快速判斷
| 摸起來／看起來 | 可能代表 | 建議 |
|---|---|---|
| 持續、柔和的震顫 | 通常是熟悉的正常狀態 | 每天繼續檢查 |
| 震顫變弱或斷續 | 可能有狹窄 | 儘快聯絡透析單位 |
| 完全摸不到震顫 | 可能有血栓或阻塞 | 不要等到下次洗腎 |
| 紅、腫、痛或發燒 | 可能有感染 | 立即就醫 |
⚠️ 溫馨提醒：如果震顫完全消失，請不要等到下一次洗腎。越早檢查、越早處理，通常越有機會把廔管保留下來。
ENGLISH
A healthy dialysis access usually has a continuous, gentle vibration called a thrill. Checking it every day is a simple and important habit.
A weaker, intermittent or absent thrill may mean narrowing or thrombosis.
- An absent thrill
- Significant arm swelling
- Prolonged bleeding after dialysis
- Cold, painful or discoloured fingers
- Redness, pain or fever
1.How should I check it?
- Place your fingertips gently over the access without pressing hard.
- Learn the usual strength and area of the thrill.
- Notice if it becomes weaker, intermittent or absent.
2.When should I not wait?
- The thrill disappears completely.
- The arm suddenly becomes swollen.
- The fingers become cold, painful or discoloured.
- The access is red and painful, especially with fever.
💡 Quick access check
| Finding | Possible meaning | What to do |
|---|---|---|
| Continuous gentle thrill | Familiar normal state | Continue daily checks |
| Weaker or intermittent thrill | Possible stenosis | Contact the dialysis unit promptly |
| No thrill | Possible clot or blockage | Do not wait until the next dialysis |
| Redness, pain or fever | Possible infection | Seek urgent care |
Note: If the thrill disappears, do not wait until your next dialysis session. Earlier treatment gives a better chance of saving the access.
