【摘要】：目的比較超聲引導(dǎo)前路坐骨神經(jīng)阻滯多點(diǎn)注射與單點(diǎn)注射技術(shù)的差異。方法選擇行足踝部手術(shù)患者90例,男47例,女43例,年齡18~68歲,ASAⅠ~Ⅲ級(jí),隨機(jī)分為多點(diǎn)注射組(M組)和單點(diǎn)注射組(S組),每組45例。超聲引導(dǎo)行前路坐骨神經(jīng)阻滯,分別給予0.5%鹽酸羅哌卡因20ml。記錄兩組坐骨神經(jīng)寬度、厚度、深度及阻滯操作時(shí)間;注射局麻藥后10、20和30min時(shí)運(yùn)動(dòng)阻滯及腓淺神經(jīng)、腓腸神經(jīng)、腓深神經(jīng)、脛神經(jīng)感覺阻滯情況;麻醉相關(guān)并發(fā)癥的發(fā)生情況。結(jié)果超聲圖像上兩組坐骨神經(jīng)寬度、厚度、深度差異無統(tǒng)計(jì)意義。M組阻滯操作時(shí)間明顯長于S組(P0.05),腓淺神經(jīng)在注藥后10、20和30 min、腓腸神經(jīng)在注藥后20和30 min、脛神經(jīng)在注藥后30min的感覺阻滯完善率M組明顯高于S組(P0.05),注藥后30 min時(shí)M組足跖屈、背伸運(yùn)動(dòng)阻滯完善率明顯高于S組(P0.05),兩組術(shù)后惡心嘔吐、耳鳴等不良反應(yīng)差異無統(tǒng)計(jì)學(xué)意義。結(jié)論超聲引導(dǎo)經(jīng)前路坐骨神經(jīng)阻滯多點(diǎn)注射局麻藥較單點(diǎn)注射需要更多操作時(shí)間,但感覺、運(yùn)動(dòng)阻滯起效快,兩組術(shù)后惡心嘔吐、耳鳴等不良反應(yīng)差異無統(tǒng)計(jì)學(xué)意義。
