對於表皮割破,用水(或生理鹽水)清潔傷口是適當的,而且往往是首選,而不是常規使用碘。
?
碘有殺菌的功效,但也對參與愈合的健康細胞有一定的風險。臨床證據並沒有清楚地表明碘比清水更能改善單純傷口的治療效果。
?
在某些情況下(例如,較深的傷口、手術環境、高感染風險的傷口),可能需要明智地使用殺菌劑(包括低濃度碘),但這是另一種情況。

謝謝鄉親們昨天對我割傷手指的關心和安慰!:))

Bottom line
- Your doctor’s approach is evidence-aligned: for superficial lacerations,?using water (or saline) to clean the wound is appropriate and often preferred, rather than routinely using iodine.
- Iodine has antiseptic benefits, but also some risks to the healthy cells involved in healing. The clinical evidence does not clearly show that iodine improves outcomes for simple wounds over clean water.。
- In some situations (e.g. deeper wounds, surgical settings, high-infection-risk wounds), judicious use of antiseptics (including low-concentration iodine) may be warranted — but that’s a different context.
