本发明公开了一种基于留置针气管插管的C57BL/6小鼠肺纤维化精准造模方法,涉及实验动物模型构建技术领域,包括如下步骤:S1实验动物分组预处理:选取体重20~30g的C57BL/6小鼠,设置空白对照组给予生理盐水、模型组给予博来霉素BLM造模药液,每组小鼠不少于8只,统一给药体积2.5mL/kg,单次气管给药,观察周期10天;S2麻醉体位固定:小鼠麻醉后仰卧置于倾斜60°操作台,固定前肢与上门齿,冷光源照明颈部,纱布牵引舌头,压舌板暴露声门。该基于留置针气管插管的C57BL/6小鼠肺纤维化精准造模方法,采用留置针和棉絮呼吸验证插管定位,解决传统盲插食道误插问题,造模成功率提升,大幅减少动物浪费。
