2、_5組、B:組和Bso組分別于切皮前10min以相應(yīng)劑量的布比卡因進(jìn)行局部浸潤麻醉,Ns組注射等溶積生理鹽水。測量術(shù)后72h各組小鼠的切El長度并計(jì)算切口愈合天數(shù)和每天切口累計(jì)愈合率。結(jié)果與Ns組相比,72h后B組、B:組的切口長度均縮短(P<0.05或P<0.01);B組與B25組、Bo組相比,切口長度縮短更為顯著(P<0.05)。B組、B25組和B。組切口愈合天數(shù)均短于Ns組,其中組愈合天數(shù)最短,B組次之,B。組最長。B組、B:組和B5。組每天切口累計(jì)愈合率均高于Ns組,其中B組最高。結(jié)論12.5mg·~、25mg·
