術後傷口負壓治療Prevena不建議用來預防常規骨科手術的傷口感染

游朝慶醫師

    自從2016年WHO發表新的預防手術部位感染指引後(Global Guidelines for the Prevention of Surgical Site Infection1,2),術後傷口負壓治療(Incisional Negative Pressure Wound Therapy,iNPWT,iVAC,ci-NPT) 便被各國普遍使用,使用最廣的商業套件應為KCI的Prevena及S&N的PICO,這條建議指引是說:『建議考慮資源的同時,在成年病人高風險傷口進行初次縫合手術時,使用預防性負壓傷口治療,也許可以預防手術部位感染』,然而近年來,這指引卻被愈來愈多的醫師濫用,對每一個乾淨傷口都使用,導至醫療的浪費,因這指引明明是說高風險傷口high-risk wounds,且其證據品質為低。

    讓我們看看骨科的共識及指引怎麼說,2018年第二次的肌肉骨頭感染全球共識會議 International Consensus Meeting on Musculoskeletal Infection (ICMMI)於美國賓州費城舉行3,有超過800個代表參加,而美國疾管局CDC在制訂預防手術部位感染指引時便參考了2013年這第一屆共識會的結論,故這一次會議的共識4其實會影響之後CDC新的指引。下面為這篇共識4的文章翻譯。

    在回顧性研究中,iNPWT對髖部及膝蓋骨折手術患者有較低的併發症及感染5,在全人工髖/膝關節再置換手術中,iNPWT也會改善傷口癒合並降低傷口染率,但對傷口裂開、深層感染及再次手術沒有影響6,7。全踝關節置換術(total ankle arthroplasty)8、長段胸椎融合手術long-segment thoracolumbar fusions9、及高風險的肌肉骨骼癌症傷口10也有相同的結論。此外,許多前瞻性隨機研究顯示iNPWT可有效降低血腫(hematoma) 、血清腫(seroma)及傷口乾掉的時間,如高能量外傷(High energy trauma,如劇烈撞擊)手術後11,半人工髖關節置換術(Hemiarthroplasty,Bipolar)12,全髖關節置換術(THA)13,及脊椎骨折手術等14。然而目前已有愈來愈多的證據說iNPWT其實在血腫、血清腫及傷口滲液的功效只是普通而已。

    無論如何,iNPWT用於常規手術並無任何好處,Redfern的研究15顯示iNPWT用於常規的THA或TKA,其淺部感染及深層感染的機會和傳統紗布一樣。有三個前瞻性隨機試驗研究iNPWT預防骨科手術感染:Crist等人16發現在非複雜性髖臼骨折的外固定手術ORIF中,深層感染的機會和傳統紗布一樣;在常規的THA及TKA手術中,也有相同的結果17,18,此外,iNPWT還會有不必要的額外費用,及可能會導致醫源性傷害,如皮膚產生水泡19,20

    最後,有證據顯示,iNPWT對術後導致的早期、良性傷口滲液也許有效。一個回顧性研究109個患有早期、良性傷口滲液的關節置換術患者,使用iNPWT的結果,發現大多數患者都能有效停止滲液,且不需要接受手術21,且沒有併發症。

     結論是,iNPWT適合用於傷口癒合困難的骨科手術患者,且沒必要常規使用於所有開刀患者,此外對於術後併發早期、良性的傷口滲液,也可以試著使用iNPWT。

  1. 醫生您好我想請問一下我有一個寬3cm深1cm的屁股傷口(疔瘡清創之後留下),我想請問您抗生素一直吃到傷口癒合嗎,因為感覺傷口要完全癒合至少要1.2個月。另外我想請問一下關於該傷口照護是否需要坐浴,因為是開放性傷口我怕坐浴會感染(現在傷口裡面的外貌就是肉色跟一點黑黑的)

    1. 1_無紅腫熱痛等蜂窩性組織炎的現象,就可以不需要抗生素
      2_若傷口離肛門口太近,滲液量太多時,則需要配合一天四次坐浴
      3_若離肛門口較遠,可使用防水敷料

    2. 謝謝醫生的回覆
      看來真的是需要時間來讓它慢慢長肉了
