【摘要】:研究目的:通過比較慢性阻塞性肺疾病急性加重期(AECOPD)并發(fā)呼吸衰竭的患者需行有創(chuàng)機(jī)械通氣治療時(shí)的人機(jī)交互性、患者做功、血清炎癥因子水平、直接脫機(jī)成功率以及機(jī)械通氣治療總時(shí)間等指標(biāo),探討神經(jīng)調(diào)節(jié)輔助通氣(NAVA)與傳統(tǒng)的同步間歇指令通氣+壓力支持通氣(SIMV+PSV)模式的差異,總結(jié)NAVA模式在AECOPD并發(fā)呼吸衰竭的患者在臨床治療中的應(yīng)用。研究方法:應(yīng)用前瞻、對(duì)照的研究方法,實(shí)驗(yàn)共納入60例AECOPD并發(fā)Ⅱ型呼吸衰竭需要有創(chuàng)機(jī)械通氣的患者隨機(jī)分為NAVA組(n=30)和SIMV+PSV組(n=30)。分別檢測(cè)兩組患者在機(jī)械通氣開始(0h)以及6h后的動(dòng)脈血?dú)馇闆r,使用NAVA-Tracker軟件檢測(cè)機(jī)械通氣1h、24h、48h、72h的人機(jī)交互性指標(biāo)(觸發(fā)延遲時(shí)間、無(wú)效觸發(fā)次數(shù)、無(wú)效觸發(fā)指數(shù)、吸呼氣轉(zhuǎn)換延遲時(shí)間等)和呼吸力學(xué)指標(biāo)(氣道峰壓值、膈肌電位峰值、患者呼吸功負(fù)荷及其在總呼吸做功的占比等),并記錄患者的直接脫機(jī)成功率以及有創(chuàng)機(jī)械通氣的總時(shí)間;酶聯(lián)免疫吸附測(cè)定法檢測(cè)機(jī)械通氣0h、24h、48h、72h患者血清炎癥因子白介素-6和白介素-8水平。結(jié)果:1.機(jī)械通氣時(shí),NAVA模式和SIMV+PSV模式對(duì)AECOPD并發(fā)Ⅱ型呼吸衰竭的氣體交換治療效果差異無(wú)統(tǒng)計(jì)學(xué)意義(P0.05)。2.在機(jī)械通氣1h、24h、48h、72h時(shí),NAVA模式下患者的吸氣觸發(fā)延遲時(shí)間、吸呼氣轉(zhuǎn)換延遲時(shí)間和呼吸做功均低于SIMV+PSV模式(P0.05);NAVA組未出現(xiàn)無(wú)效觸發(fā),其無(wú)效觸發(fā)次數(shù)和無(wú)效觸發(fā)指數(shù)與SIMV+PSV組差異有統(tǒng)計(jì)學(xué)意義(P0.05)。通氣支持程度:神經(jīng)調(diào)節(jié)輔助通氣組氣道支持壓力與膈肌電位峰值呈顯著正相關(guān)(r=0.95,P0.05),SIMV+PSV組的氣道支持壓力與膈肌電位峰值之間未見顯著相關(guān)性(P0.05)。3.NAVA組呼吸機(jī)相關(guān)性肺損傷相關(guān)的部分炎癥因子水平低于SIMV+PSV組:在有創(chuàng)機(jī)械通氣開始時(shí),兩組患者血清中的IL-6和IL-8基礎(chǔ)水平差異無(wú)統(tǒng)計(jì)學(xué)意義(P0.05);行機(jī)械通氣治療72h后,NAVA組的患者血清IL-6和IL-8水平均呈現(xiàn)總體下降趨勢(shì);SIMV+PSV組患者的血清IL-6水平總體呈升高趨勢(shì),IL-8水平則在機(jī)械通氣48h內(nèi)逐漸降低,而后升高。4.將直接脫機(jī)成功率相比較,NAVA組和SIMV+PSV組之間未見明顯差異(P0.05),而有創(chuàng)機(jī)械通氣治療總時(shí)間方面,NAVA組則比SIMV+PSV組明顯縮短(P0.05)。結(jié)論:在AECOPD并發(fā)呼吸衰竭患者行有創(chuàng)機(jī)械通氣治療過程中,相比于SIMV+PSV模式,NAVA模式可以更好地改善人機(jī)交互性,有效避免呼吸肌疲勞的出現(xiàn),降低發(fā)生VALI相關(guān)的炎癥反應(yīng),縮短機(jī)械通氣時(shí)間,從而改善患者的預(yù)后。
