电子咽喉镜检查中应用粘膜表面麻醉剂的必要性探讨

The Necessity of Applying Mucosal Surface Anesthetic in Electronic Laryngoscopy

摘要: 目的：探讨患者咽喉镜检查前接受表面麻醉的必要性。方法：将我院2018年4月至2018年7月门诊申请电子喉镜检查的患者共865例进行随机分组，A组：喉镜检查前没有使用表面麻醉，只有在检查之前安慰病人，并详细告知相关注意事项；B组：检查前使用1%丁卡因粘膜表面麻醉，并告知患者注意事项。观察有效率及不良反应发生情况。结果：两组患者在年龄、性别方面差异无统计学意义(P > 0.05)；两组的有效率差异无统计学意义(P > 0.05)；两组不良反应发生率差异有统计学意义，B组不良反应发生率明显高于A组(P < 0.001)。结论：不使用粘膜表面麻醉可以提高舒适度，减少麻醉药物使用后不良反应的发生率。

Abstract: Objective: To explore the necessity of receiving topical anesthesia before laryngoscopy. Methods: A total of 865 patients who underwent laryngoscopy in our hospital from April 2018 to July 2018 were randomly assigned. Group A: No topical anesthetics were used before the examination. Only the patients were comforted before the examination, and the patients were informed in detail; Group B: 1% tetracaine mucosal surface anesthesia was used before examination and patients were informed of precautions. The effective rate and adverse reactions were observed. Results: There was no significant difference in age and gender between the two groups (P > 0.05). There was no significant difference in the effective rate between the two groups (P > 0.05). There was a statistically significant difference in the incidence of adverse reactions between the two groups. The incidence of reaction was significantly higher than that of group A (P < 0.001). Conclusion: No mucosal surface anesthesia can improve comfort and reduce the incidence of adverse reactions after anesthetic use.
