【摘要】:目的探討不同呼氣末正壓通氣對(duì)腹腔熱灌注化療患者呼吸力學(xué)及肺功能的影響。方法選擇擇期行腹膜癌熱灌注化療的患者90例,男55例,女35例,年齡40~70歲,ASAⅠ~Ⅲ級(jí)。隨機(jī)分為三組,每組30例。A組為容量控制通氣(VCV)組,VT10 ml/kg;B組為VCV+低PEEP組,VT6ml/kg,PEEP 5cm H_2O;C組為VCV+高PEEP組,VT6ml/kg,PEEP 10cm H_2O;術(shù)中調(diào)整RR維持PETCO2 35~45 mm Hg。于氣管插管后5 min(T_1)、腹腔熱灌注化療開(kāi)始前(T2)、化療結(jié)束時(shí)(T_3)、氣管拔管前(T4)記錄氣道峰壓(Ppeak)、氣道平臺(tái)壓(Pplat)和平均氣道壓(Pmean),計(jì)算動(dòng)態(tài)肺順應(yīng)性(C_(dyn))。并取橈動(dòng)脈血進(jìn)行血?dú)夥治?計(jì)算氧合指數(shù)(OI)、呼吸指數(shù)(RI)、肺泡-動(dòng)脈血氧分壓差(A-aDO_2)及死腔率(VD/VT)。記錄術(shù)后7d內(nèi)肺部相關(guān)并發(fā)癥情況。結(jié)果與A組比較,T_1~T_4時(shí)B、C組Ppeak、Pplat、A-aDO_2和RI明顯降低,OI和VD/VT明顯升高(P0.05);T_2~T_4時(shí)B、C組Pmean明顯降低,Cdyn和PaO_2明顯升高(P0.05)。與T_1比較,T_2~T_4時(shí)A組Ppeak、Pplat和Pmean明顯升高,C_(dyn)明顯降低(P0.05);T_3時(shí)B組Ppeak和Pplat明顯升高(P0.05),T_2~T_4 Pmean明顯升高(P0.05),T3、T4時(shí)C_(dyn)明顯降低(P0.05);T_2~T_4時(shí)C組Ppeak、Pplat和Pmean明顯升高(P0.05),T_3、T_4時(shí)Cdyn明顯降低(P0.05)。與T0時(shí)比較,T2~T4時(shí)三組PaO_2和OI明顯降低,A-aDO_2、RI和VD/VT明顯升高(P0.05)。術(shù)后7d內(nèi)B、C組肺部感染、低氧血癥和肺不張的發(fā)生率明顯低于A組(P0.05)。結(jié)論小潮氣量(6ml/kg)聯(lián)合PEEP(5cm H_2O)通氣可以顯著改善腹膜癌患者術(shù)中熱灌注期間肺功能,降低圍術(shù)期肺部并發(fā)癥的發(fā)生風(fēng)險(xiǎn)。
