奥布卡因与丁卡因在电子喉镜检查中的麻醉效果

Anesthesia effect of obucaine and tetracaine in electronic laryngoscopy

目的研究常规电子喉镜检查中奥布卡因与丁卡因的表面麻醉效果。方法将进行电子喉镜检查的132例受检者随机分为奥布卡因组与丁卡因组,各66例,分别采用口服奥布卡因凝胶和丁卡因喷雾进行黏膜表面麻醉。对两组受检者麻醉效果、检查后视觉模拟评分(VAS)、满意度及不良反应发生情况进行比较。结果两组受检者的麻醉总有效率及VAS评分比较,差异无统计学意义(P>0.05);奥布卡因组检查满意度高于丁卡因组(P<0.05);丁卡因组不良反应总发生率高于奥布卡因组(P<0.05)。结论口服奥布卡因凝胶在电子喉镜检查中麻醉效果与丁卡因喷雾无明显差异,但口服奥布卡因凝胶受检者满意度更高,口服奥布卡因凝胶较丁卡因喷雾更安全。

Objective To study the effect of surface anesthesia with obucaine and tetracaine in routine electronic laryngoscopy.Methods A total of 132 examiners who underwent electronic laryngoscopy were randomly divided into obucaine group and tetracaine group, with 66 cases in each group, which were given oral obucaine gel and tetracaine spray respectively for mucosal surface anesthesia.The effects of anesthesia, visual analogue score (VAS), satisfaction and adverse reactions were compared between the two groups.Results There were no significant differences in the total effective rate of anesthesia and VAS score between the two groups (P>0.05).The satisfaction of anesthesia in the obucaine group was higher than that in the tetracaine group (P<0.05).The total incidence of adverse reactions in the tetracaine group was higher than that in the obucaine group (P<0.05).Conclusion The anesthetic effect of oral orbucarin gel in the electronic laryngoscopy is not significantly different from that of tetracaine spray.The oral orbucaine gel is more satisfactory for the examiners and it is safer than tetracaine spray.
