【摘要】 目的  比较利多卡因不同剂量预处理对罗库溴铵注射痛的影响。 方法  120例行全身麻醉择期手术的患者按照完全随机的方法分为利多卡因10 mg 3 mL预处理组（A组），利多卡因25 mg 3 mL预处理组（B组），利多卡因50 mg 3 mL预处理组（C组），生理盐水3 mL预处理组（D组）。观察不同剂量的利多卡因预处理对罗库溴铵注射痛的影响。 结果  A、B、C和D组注射罗库溴铵的疼痛发生率分别为53%、27%、3%和90%。与生理盐水预处理组相比，利多卡因预处理组能明显减轻罗库溴铵引起的注射痛（P lt;0.01）；剂量越大，效果越明显。 结论  利多卡因10、25、50 mg预处理均能显著降低罗库溴铵注射时引起的疼痛，以50 mg利多卡因更为有效。

The effects of different doses of lidocaine pretreatment on injection pain of rocuronium were observed. Results  The pain incidence from injection with rocuronium in A, B, C, D groups were 53%, 27%, 3% and 90% respectively. The higher dose of lidocaine, the more obvious effect.
