目的 探討高頻震蕩通氣(HFOV)和常規(guī)機(jī)械通氣(CMV)及其聯(lián)合肺表面活性物質(zhì)(PS)對(duì)重度蒸汽吸入性肺損傷并呼吸衰竭的治療效果。方法 新西蘭大白兔37只制成重度蒸汽吸入性肺損傷并呼吸衰竭模型,隨機(jī)分為五組,采用四種方法進(jìn)行通氣治療(CMV,HFOV,CMV+PS及HFOV+PS),分別在治療后1,2,3及4 h取動(dòng)脈血行血?dú)夥治?。治? h后處死動(dòng)物,取右肺下葉稱重后,計(jì)算濕質(zhì)量/干質(zhì)量比值(W/D);右肺中葉4個(gè)不同部位(依賴區(qū)和非依賴區(qū))取標(biāo)本,行病理學(xué)檢查。對(duì)照組不行機(jī)械通氣。結(jié)果 傷后PaO2均降至60 mm Hg 以下,各組傷前、傷后組內(nèi)比較均有顯著性差異(P lt;0.01),各組PaCO2傷前、傷后組間比較均無顯著性差異(P gt;0.05)。4個(gè)治療組的PaO2均在通氣治療1 h后明顯上升,通氣治療4 h內(nèi)PaO2維持在良好水平。HFOV組和HFOV+PS組的PaO2分別高于CMV組和CMV+PS組(P lt;0.01,P lt;0.05);CMV+PS組在傷后2 h,HFOV+PS組在傷后2和3 h,PaO2明顯優(yōu)于相應(yīng)未加PS組(P lt;0.05)。肺泡氣-動(dòng)脈血氧分壓差[P(A-a)O2]在HFOV組和HFOV+PS組分別低于CMV組和CMV+PS組(P lt;0.01,P lt;0.05);CMV+PS組和HFOV+PS組在治療2,3及4 h,P(A-a)O2均分別顯著低于CMV組和HFOV組(P lt;0.05)。4個(gè)治療組傷后各時(shí)點(diǎn)的PaCO2均無明顯變化(P均 gt;0.05);傷前、傷后各時(shí)點(diǎn)的動(dòng)脈壓和中心靜脈壓也無明顯變化(P均 gt;0.05)。肺組織W/D在HFOV和CMV組,HFOV+PS組和CMV+PS組間比較均無顯著性差異(P均 gt;0.05);加用PS組與相應(yīng)未加PS組比較有顯著性差異(P lt;0.05)。肺組織病理學(xué)檢查發(fā)現(xiàn)HFOV組的損傷程度較CMV組明顯減輕,HFOV+PS組損傷最輕,CMV組損傷最重。結(jié)論 HFOV聯(lián)合PS能提高蒸汽吸入性損傷兔的PaO2,減輕肺損傷,且對(duì)循環(huán)功能無不良影響,是治療吸入性損傷并呼吸衰竭較好的方法。
