GFHDT: 小傷口別忽視! 記住急救四步法和破傷風疫苗接種

小傷口別忽視! 記住急救四步法和破傷風疫苗接種


27 Oct 2025 at 11:16pm



近期,東莞的李先生遭遇了一場因忽視小傷口而導致的悲劇。 他在走路時被地上的樹枝刺傷右腳,當時傷口較小,他就僅用創可貼簡單處理了一下。 幾天後傷口出現紅腫、發熱癥狀,他還是沒去就醫,自行買葯處理。 十余天后,病情急劇惡化,右腳大量流膿、組織壞死,還伴隨全身休克癥狀。 最終他被緊急送往東莞市人民醫院普濟院區,被診斷為重度蜂窩織炎,醫生為挽救其生命不得不進行右下肢截肢手術。 這一事件典型地揭示了公眾對皮膚傷口認知的普遍誤區,看似微小的穿刺傷,一旦忽視處理,就可能引發致命感染。

殊的感染風險。 其傷口形態深而窄,容易形成缺氧環境,這可是破傷風桿菌等厭氧菌繁殖的“溫床”。 破傷風桿菌孢子通過傷口進入體內後會產生毒素,引發肌肉強直性痙攣,致死率高達30%。 感染會從局部紅腫逐步發展到組織壞死、全身膿毒癥。 就像李先生,延誤治療使得感染不斷擴散,最終導致了嚴重後果。 而很多人常因傷口表淺或面積小就忽視處理,完全沒意識到深層組織損傷和隱性感染的風險。

高危人群:更需警惕小傷口

糖尿病患者、老年人和免疫缺陷者是易感染的高危人群。 糖尿病患者神經病變會導致疼痛感知遲鈍,高血糖環境又利於細菌繁殖; 老年人血液迴圈差、免疫功能下降,傷口癒合慢; 免疫缺陷者如HIV感染者或化療患者,感染控制能力弱。 當這些高危人群被刺傷時,預警信號的識別尤為重要。 局部癥狀方面,若紅腫範圍每小時擴大超過1cm、有持續跳痛、出現波動感(意味著膿腫形成); 全身表現為體溫>39C、寒戰、意識模糊等,這可能就是膿毒症的前兆。 要是李先生是糖尿病患者,那他的傷口惡化速度可能更快,更需要更早干預。

急救四步法:抓住黃金救治時間

傷口處理有現場急救四步法。 第一步是沖洗,用流動清水或生理鹽水沖洗15分鐘,這能「沖走90%污染物」; 第二步去汙,用無菌鑷子清除可見異物,千萬別擠壓傷口; 第三步消毒,用碘伏擦拭,相比酒精,碘伏刺激性小,這是臨床指南推薦的; 第四步就醫,要在24小時內完成破傷風疫苗接種及清創,這可是黃金時間。 對於醫療干預,傷口深度>0.5cm或污染嚴重的,需注射破傷風抗毒素; 發熱>38C後48小時內必須啟動抗生素治療,不然感染控制成功率會下降70%。

預防為主:個人與社會共努力

個人防護要做好,戶外

活動時穿防刺鞋具,帶好含生理鹽水、無菌敷料的急救包。 高危人群每10年要定期接種破傷風疫苗,還得建立傷口處理應急聯繫人機制。 社區也要加強健康教育,在公園、工地等高風險區域設置穿刺傷急救提示牌,醫院急診科推行“穿刺傷快速評估 - 處置 - 隨訪”標準化流程。 同時,推廣「傷口分級診療」模式,讓基層醫療機構配備簡易清創包,縮短救治延遲。 李先生的遭遇給我們敲響了警鐘,微小傷口的致命性取決於處理時機和科學認知。 “破傷風感染無小事”,高危人群要隨身攜帶醫療記錄卡,普通市民要掌握急救四步法,通過個體與社會的共同努力,減少類似悲劇的發生。
