摘要: 目的 探索建立一种操作便捷而高效的大鼠非暴露式气管滴注方法。方法 选用自制一次性静脉留置针在头灯的照射下行气管插管,用1 mL注射器吸取0.1 mL生理盐水对10只SD雄性大鼠(体质量200~350 g)以2日1次的频率重复操作。结果 共完成40次气管滴注的操作,每只动物的操作耗时约3 min,整个实验操作安全顺利,并未给动物造成创伤,实验过程中及实验结束3 d后动物均无异常反应。结论 该气管滴注方法具有快捷、安全和高效的特点,可广泛应用于大鼠呼吸道给药相关实验研究。

Abstract: Objective To explore a new method for the operation of a rat model of non- exposed tracheal instillation. Methods Tracheal intubation with a self made disposable intravenous indwelling needle in the irradiation under a strong light, 0.1 mL saline was administered repetitive operation to 10 SD male rats (200-350 g) by 1 mL syringe with the frequency of once per two days. Results A total of 40 operations were performed, each animal took about 3 minutes. The whole experiment was safe and smooth, and the animals were not injured. During the experiment and the end of the experiment,animals had no abnormal reaction after three days. Conclusion This method is rapid, safe and effective, it can be widely used in the experimental study of respiratory tract administration in rats.
