目的 探討雙相氣道正壓通氣(Bilevel),VV+[自主呼吸與目標(biāo)容量通氣的結(jié)合,由兩種不同的以容量為目標(biāo)的呼吸方式組成:壓力調(diào)節(jié)容積控制(VC+)和容量支持通氣(VS)]治療慢性阻塞性肺疾?。–OPD)急性呼吸衰竭的效果。方法 COPD急性呼吸衰竭需行有創(chuàng)機(jī)械通氣的患者63例,機(jī)械通氣支持24 h以上。首先應(yīng)用輔助-控制(A/C)通氣模式進(jìn)行機(jī)械通氣2~4 h,獲得適合于患者的基礎(chǔ)通氣參數(shù),同時(shí)測定基礎(chǔ)血流動力學(xué)和氧動力學(xué)參數(shù)。穩(wěn)定2~4 h后隨機(jī)選用Bilevel,VC+或A/C通氣模式,三種通氣模式下設(shè)置同樣參數(shù),相應(yīng)分為Bilevel組、VC+組和A/C組。Bilevel組在撤機(jī)過程中,在每一個(gè)壓力水平,分別予以Bilevel模式和壓力支持通氣(PSV)模式,相應(yīng)分為Bilevel組和PSV 1組。VC+組在撤機(jī)過程中,將通氣模式先后調(diào)整為VS模式和PSV模式,相應(yīng)分為VS組和PSV 2組。每種模式持續(xù)30 min,穩(wěn)定后測定通氣功能和血?dú)鈪?shù),同時(shí)監(jiān)測肺力學(xué)指標(biāo)。結(jié)果 在COPD急性呼吸衰竭患者行機(jī)械通氣治療初期,Bilevel,VC+下的氣道峰壓較A/C時(shí)的氣道峰壓明顯降低,而順應(yīng)性較A/C時(shí)高。Bilevel和A/C對患者的肺泡通氣和氧合改善的效應(yīng)無明顯差別。循環(huán)功能和血?dú)飧髦笜?biāo)兩組間比較無顯著差異(P gt;0.05)。在撤機(jī)過程中,Bilevel,VV+產(chǎn)生的效應(yīng)與PSV基本相同,其呼吸形式和血?dú)飧淖儫o顯著差異(P gt;0.05)。結(jié)論 Bilevel和VV+模式治療COPD急性呼吸衰竭較A/C時(shí)的氣道峰壓低,順應(yīng)性高,撤機(jī)過程中產(chǎn)生的效應(yīng)和PSV基本相同,故可用于COPD急性呼吸衰竭治療的全過程。
