1、全麻下高頻噴射通氣在小兒氣道異物取出術(shù)的應(yīng)用【關(guān)鍵詞】高頻 摘要：目的：觀察靜脈復(fù)合全麻下高頻噴射通氣（HFJV）在小兒氣道異物取出術(shù)的臨床效果。方法：患兒在進(jìn)入手術(shù)室前肌注氯胺酮4～8mg/kg，待患兒安靜入睡后進(jìn)手術(shù)室，開通靜脈通道后緩慢注射羥丁酸鈉（r-OH）80～100mg/kg，約10min后以1%地卡因作喉部表面霧化噴入，較大患兒于環(huán)甲膜穿刺注入1%地卡因1ml，5min后即可手術(shù)，手術(shù)時間超過90min者，可追加氯胺酮、r-OH等。術(shù)中HFJV采用國產(chǎn)KR-Ⅱ呼吸機(jī)，電控氣動進(jìn)行噴射通氣，頻率根據(jù)缺氧程度選用1
2、44～200次/min，氣源驅(qū)動壓0.6～1.2kg/cm2。結(jié)果：術(shù)中麻醉平穩(wěn)、缺O(jiān)2改善，52例氣管、支氣管異物的患兒在靜脈復(fù)合全麻下行高頻噴射通氣均順利完成手術(shù)。結(jié)論：靜脈復(fù)合全麻下行HFJV在小兒氣道異物取出術(shù)的應(yīng)用效果是確切的?！ ￡P(guān)鍵詞：高頻噴射通氣；小兒；氣管異物取出 TheApplicationofGeneralAnesthesiaHigh-frequencyJetVentilation intheInfantileAirPassageForeignBodyExtraction Abstract：Obje
