首頁醫療資訊優質醫學安慰劑效應是否適用於手術?

安慰劑效應是否適用於手術?

來自: Medix團隊

「心靈勝於物質」是一個經典用語,但醫學研究證明,它比想像的更真實

我們都聽過安慰劑效應,但我們通常把它與糖丸和祖母療法聯想到一起。實際上,研究新療法時考慮安慰劑效應的可能性是至關重要的。例如,100人接受新的藥物治療,50人在短時間內完全康復;我們可以總結治療是有效的,但如發現當中有35人是因安慰劑效應而得到改善,那我們對治療的看法就完全不同了,不是嗎?

 

當研究新藥時,我們一定會想到安慰劑效應;但是為什麼不把相同的邏輯應用於手術呢?比較手術和安慰劑雖然存在一定的道德爭議,但純粹從醫學角度來看,它可能對全球的臨床實踐產生巨大的影響。

 

著名的《英國醫學雜誌》曾發表過一篇針對此問題的研究和文章。研究人員比對了臨床試驗中涉及真實手術與安慰劑手術(稱為假手術)的部份,以了解它如何影響結果。大多數的試驗是針對小型的手術,其主要目的是改善功能性和生活質量。

 

試驗結果顯示,有74%進行假手術(安慰劑)的患者狀況得到改善。此外,在51%的個案中,真實治療相對假手術並沒有明顯優勢,讓研究人員嚴重質疑真實治療的有效性。 這驚人的結果,不禁讓研究人員對現有手術的成效產生懷疑,擔心其效果會遭安慰劑試驗影響。

 

更多的研究對假手術提出有趣的見解:安慰劑效應主要在功能有限的情況下起作用,但是並不能改善癌症等嚴重狀況。其次,安慰劑效應的有效程度與治療的複雜性和侵入性相關;對藥物有效果,對注射的效果更好,但對實際手術的影響仍然最可觀。

 

既然安慰劑效應已被證明對手術有可觀影響,那患者可以做什麼呢?不是否定手術的必需性,而是更建議患者與經驗豐富的知名專家進行諮詢,降低進行不必要手術的風險。專家們對這些問題有更深認識,並能有效辨別治療的效用。其次,由專家覆核放射影像是非常重要的。在一般情況下,病人感到疼痛會進行影像學檢查,放射科醫生會發現偶然成因,意味著真正引起疼痛的原因並沒被發現。在此基礎上,外科醫生執行手術,疼痛也得以消除,但這很有可能是因為安慰劑效應,而不是機於實際的治療。有經驗的放射科醫生和專家有足夠的經驗分辨出真實病因,並助你找到無創的替代治療。最後,請尋求更全面的治療—一個把你的身體和精神狀況都全部列入考量的治療。
