目的探讨咽反射异常敏感患者拍摄根尖片时局部涂擦丁卡因的麻醉效果及不良反应发生情况。方法将拍根尖片且咽反射异常敏感的146例患者随机分为观察组(76例)和对照组(70例),观察组采用丁卡因局部涂擦法进行表面麻醉,对照组采用喉头喷雾方法。结果表面麻醉显效率观察组为89.5%,对照组为82.9%,两组比较,差异无显著性意义(P>0.05);观察组不良反应发生率为65.8%,对照组为97.1%,两组比较,差异有显著性意义(P<0.01)。结论局部涂擦丁卡因表面麻醉,能减轻咽反射异常敏感患者拍摄根尖片时的痛苦,减少不良反应的发生,是一种简单易行、安全有效的口腔表面麻醉方法。
Objective To investigate the anesthetic effects and side effects of topical tetracaine injection in patients with sensitive gag reflexes. Methods One hundred and sixty-six patients were randomly divided into observation group (76 cases) and control group (70 cases). The observation group was given topical anesthesia with tetracaine topical rubbing method while the control group was treated with throat Spray method. Results The apparent efficiency of surface anesthesia was 89.5% in the observation group and 82.9% in the control group, with no significant difference between the two groups (P> 0.05). The incidence of adverse reactions in the observation group was 65.8% and in the control group was 97.1% The difference was significant (P <0.01). Conclusion Topical anesthesia with tetracaine can alleviate the pain of apical transection in patients with sensitive gag reflex and reduce the incidence of adverse reactions. It is a simple, safe and effective oral anesthetic method.
