摘要 目的观察手术结束前静脉注射右美托咪定(Dex)1μg/kg对唇腭裂修补术患儿苏醒及拔管前后气道不良反应的影响。方法将先天性唇腭裂患儿30例(ASAⅠ~Ⅱ级)随机分成Dex(D组)和对照组(C组)。两组患儿均以8%七氟醚面罩诱导(8 L/min)入睡后开放静脉,顺序静脉注射咪达唑仑0.2 mg/kg,芬太尼3μg/kg,丙泊酚2 mg/kg,顺阿曲库铵0.04 mg/kg诱导,行气管插管全身麻醉后,D组术毕前30 min使用微量泵10 min内泵注Dex 1μg/kg,C组则泵注生理盐水。记录小儿诱导前(基础值,T0)、插管前、插管后即刻、插管后5 min、术毕前20 min、术毕、拔管时、拔管后(T1~T7)患儿的生命体征(ECG、MAP、HR、SpO2),观察停药至恢复自主呼吸的时间及不良事件(拔管时是否躁动、需要托下颌、重新气管插管、气道痉挛、氧饱和度最低值),并记录Ramsay镇静评分。结果两组T0~T7期间HR、MAP、SpO2变化相似(P>0.05);D组恢复自主呼吸的时间[(12±4.2)min]与C组[(11±6.0)min]基本一致(P>0.05),但D组需要托下颌辅助患儿概率明显小于C组(P<0.05),D组与C组出现气道痉挛者分别为1例(6.7%)和3例(20%);D组患儿无烦躁,而C组有3例(20%);两组均无需要重新气管插管病例。结论唇腭裂修补手术结束前静脉注射Dex(1μg/kg)对患儿苏醒期具有安静和舒适作用,拔出气管导管过程中患儿无烦躁,可有效地降低气道高敏反应性,可在临床选用。
