第三章 文獻查證
四、 結 果
(一) 回顧一研究目的: 呼吸訓練介入對腦中風病人之成效
回顧一針對篩選出的二篇文獻進行評析,評析結果整理於表3-3, 3-4及表3-5。
整體而言,二篇文獻的樣本數都少,分組後的各組樣本,最多僅15人,少到10人 一組。納入樣本都屬中風存活期(Britto et al., 2011)或中風後半年(Sutbeyaz et al., 2010) 之居家病人。呼吸訓練方案主要分成二大類: (1)機械輔助加阻力呼吸訓練,所設定 的阻力閾值為最大吸氣壓力(MIP)值的30%~60%。(2)自主式呼吸再訓練,訓練方案 時程都是8周。另改良式Jadad品質量表得分為7及5分,文獻品質理想。
Cochrane偏差風險評估結果(表3-4)顯示,文獻一的各項偏差都呈現低風險;
文獻二部分有較高風險的選樣偏差,結果偵測/測量偏差(detection bias)方面,因文中 說明不完整而無法確認,無法排除可能有此風險。
成效部分,機械輔助加阻力呼吸訓練方案對整體肺功能、吸氣肌功能的改善二 文獻都呈現顯著差異,生活品質(SF-36)、Barthel Index and Functional Ambulation scores一篇文獻達統計顯著差異(Sutbeyaz et al., 2010),但2011年的另一篇文獻則顯 示生活品質(NHP)及功能實作測試(functional performance)皆未達統計差異 (Britto et al., 2011)。自主式呼吸再訓練方案僅有一篇文獻結果,主要呈現對吐氣肌功能
(PEmax)及部分生活品質變項的顯著改善成效,在Barthel Index及吸氣肌功能(MIP)
改善僅呈現優於前測組內差異效益。
不良反應部分,二篇文獻都未描述。
(二) 回顧二研究目的: 疾病早期自主式呼吸(再)訓練方案發展
基於系統性文獻回顧一之初步發現,並考量急性腦中風後早期階段,病患呼吸 肌力量顯著不足問題。為避免吸氣肌訓練時過度吸氣負荷造成橫膈膜疲憊風險 (Walker et al., 2016),低成本、自主式呼吸(再)訓練方案成為作者在建構這群病患呼 吸訓練方案的主要核心元素,特別是於 1950 年代中期就被正式命名的蹶嘴式呼吸 (pursed-lips breathing, PLB)法(Fregonezi, Resqueti, & Guell Rous, 2004),深具改善呼
52
吸功能價值(Dechman & Wilson, 2004; Fregonezi et al., 2004; Gosselink, 2004),目前 PLB 研究的主要問題是沒有標準的PLB訓練方法,Tiep (2007)強調應建立普及的
PROTOCAL增加其可應用性。
本論文文獻經圖3-2的篩選流程後,共選出29篇文獻進行評析,評析結果整 理列於下頁表3-6。自主呼吸訓練方案內容彙整於表3-7,預計於pilot study時進行 測試。
