摘要 目的 观察丁卡因凝胶(利宁)预防七氟烷吸入麻醉下小儿气管异物取出术中屏气、缺氧的效果.方法 将30例气管或支气管异物患儿按信封抽签法随机分为两组:利宁组(15例)所用支气管镜表面均匀涂抹利宁;对照组(15例)所用支气管镜表面未做任何处理,两组均用七氟烷吸入麻醉.观察两组患儿术中屏气程度和最低脉搏血氧饱和度(SpO2),中度屏气患儿术中需再开大七氟烷吸入浓度,术后进行视觉模拟评分(VAS).结果 利宁组中重度屏气3例(20.0%),对照组11例(73.3%),两组比较差异有统计学意义(P<0.01).利宁组术中最低SpO2明显高于对照组(P<0.05).利宁组最低SpO2<0.90、术中需再开大七氟烷吸入浓度例数明显少于对照组(P<0.05).术后利宁组VAS对麻醉满意度评分明显高于对照组(P<0.05).术中及术后24h无一例患儿出现局麻药中毒及与利宁有关的不良反应.结论 利宁能够明显降低七氟烷吸入全麻下小儿气管异物取出术中屏气、缺氧的发生率和程度.
