【摘要】:目的評價不同間隔時間行程控硬膜外脈沖式注射(programmed intermittent epidural bolus,PIEB)或連續(xù)硬膜外輸注(continuous infusion epiduaral,CEI)復合PCEA用于分娩鎮(zhèn)痛的效果。方法選擇有分娩鎮(zhèn)痛要求的足月初產(chǎn)婦186例,ASAⅠ或Ⅱ級,采用數(shù)字表法隨機分為三組,每組62例。三組均使用首次劑量(0.125%羅哌卡因+0.4μg/ml舒芬太尼)10 ml,鎮(zhèn)痛泵均使用(0.08%羅哌卡因+0.4μg/ml舒芬太尼)100ml。PIEB1組(P1組):5ml/30min,首次劑量注入30min后開始脈沖給藥;PIEB2組(P2組):10 ml/60 min,首次劑量注入60 min后開始脈沖給藥;CEI組(C組):10ml/h,首次劑量注入后立即開始持續(xù)給予背景劑量。三組均設置PCA量5ml,鎖定時間30min。記錄鎮(zhèn)痛期間宮縮疼痛VAS評分、運動阻滯程度Bromage評分、VAS評分3分的例數(shù)和(MBS)評分1分的例數(shù);記錄最高感覺阻滯平面、鎮(zhèn)痛藥物用藥總量、催產(chǎn)素使用量、PCEA按壓次數(shù),第一次追加藥物時間、產(chǎn)程時間、分娩方式和產(chǎn)間發(fā)熱的例數(shù);記錄不良反應的發(fā)生情況。結(jié)果三組在分娩鎮(zhèn)痛開始后VAS評分均明顯低于鎮(zhèn)痛前,P2組VAS3分的比率明顯低于P1組和C組(P0.05)。鎮(zhèn)痛期間,P1組最高感覺阻滯平面明顯高于P2組和C組,P2組單側(cè)阻滯發(fā)生率明顯低于C組(P0.05)。P2組鎮(zhèn)痛藥物用藥總量、PCEA按壓次數(shù)明顯少于,第一次追加藥物時間明顯長于P1組和C組(P0.05)。P1組與P2組器械助產(chǎn)與產(chǎn)間發(fā)熱的例數(shù)明顯少于C組(P0.05)。結(jié)論在分娩鎮(zhèn)痛中給予首次劑量后,間隔60min行PIEB模式注射技術(shù),是一種更有效的給藥方法。
