氧化亚氮吸入和异丙酚静脉超浅麻醉在拔牙应用中的比较

The comparative study of the ultra-light anaesthesia between N_2O inhalation and propofol intravenous in tooth extraction

目的研究氧化亚氮吸入与异丙酚静脉超浅麻醉在拔牙中的效果。方法选择门诊ASAI级（美国麻醉学会组1组）下颌智齿拔除患者40例，随机分为两组，一组为氧化亚氮组，年龄20～36岁，另一组为异丙酚组，年龄21～35岁，在超浅麻醉辅以局麻下拔牙。结果两组患者，术前、术中、术后的血压、脉搏、呼吸、血氧饱和度维持平稳，治疗操作在患者配合下顺利完成，术后有一定的遗忘作用，副作用小，30min内都达到了离院回家标准。结论两组患者拔牙过程中均获得了满意的效果，但氧化亚氮组的止痛作用优于异丙酚组。

Objective To study the effect of N2O inhalation and propofol intravenous anaesthesia in tooth extraction. Methods 40 dental outpatients with the extraction of the mandibular wisdom tooth, ASAl,were randomly allocated to two groups: N2O group with the age of 20-36 years old and propofol group with the age of 21-35 years old. All cases undergoing dental extraction were given ultra-light anaesthesia as an adjunct local anaesthesia. Results The two groups were gained various levels of sedation, there were no significant difference among BP,HR, RR,SPO2 before,in,and after the operation. Dental treatment could be carried out in cooperating condition throughout the whole procedure. There was a certain extent ofamnesia postoperation, the incidence of postoperative side effects was low, the recovery timewas gained within 30 minutes. Conclusion The analgesic effects of NZO group were superiorto the propofol group.[
