摘　　要：目的探讨笑气/氧气混合吸入镇静镇痛技术在牙拔除术中的临床应用效果。方法需行双侧下颌阻生智齿及双侧正畸减数拔牙患者各50例,同一患者随机选择一侧行笑气/氧气镇静镇痛加局部麻醉,该侧为实验组。另一侧只行局部麻醉,为对照组。记录拔牙过程中患者血压、心率及血氧饱和度变化,并进行疼痛程度评分(VAS评分)。结果患者在两种不同麻醉方法下行牙拔除术的过程中,镇静镇痛的效果、生命体征变化评估比较均有显著统计学差异(P<0.05)。结论笑气/氧气混合吸入镇静镇痛技术减轻了患者的疼痛和恐惧,具有良好的镇静镇痛作用,安全、作用快而安全,苏醒也快,值得临床推广使用。Objective To discuss the clinical effects of nitrous oxide/oxygen inhalation conscious sedation techniques on extraction. Methods 50 cases of bilateral mandibular third molar extraction and 50 bilateral orthodontic meiotic extraction patients were required. Nitrous oxide/oxygen inhalation conscious sedation and local anesthesia were performed on one side of one patient randomly, which was the experimental group, and the other side was subjected to extraction under local anesthesia only, working as the control group. The changes of blood pressure, heart rate and oxygen saturation in the extraction process were recorded. The pain level was analyzed with visual analogue scale（VAS）. Results As for patients subjected to two different anesthetic methods in the process of tooth extractlon,there was statistical- ly significant difference in sedation analgesia, vital signs assessments （P 〈 0.05）. Conclusions Nitrous oxide/oxygen inhalation con- scious sedation,which has a good sedative and analgesic effects,is safe and effective in reducing the patient＇s pain and fear in extraction, thus worth wide clinical use.
