目的:评价笑气/氧气吸入镇静技术在急性牙髓炎治疗中的临床效果。方法:选择2012年9月—2013年3月收治的急性牙髓炎患者72例,随机分为2组,实验组患者(37例)在笑气/氧气吸入镇静辅以局麻下开髓,对照组(35例)仅在局麻下开髓。利用临床焦虑与合作行为级别和WHO临床疼痛评估标准对患者进行评估,采用SPSS 14.0软件包对数据进行秩和检验和χ2检验。结果:临床焦虑与合作行为级别评估中,实验组表现自如者占86.5%,对照组仅为42.9%;临床疼痛评级实验组94.6%选择无痛,对照组68.6%选择无痛,差异显著(P<0.01)。结论:笑气/氧气吸入镇静技术用于急性牙髓炎治疗可获得良好的镇痛、镇静效果。
OBJECTIVE: To evaluate the clinical efficacy of nitrous oxide / oxygen inhalation sedation in the treatment of acute pulpitis. Methods: Seventy-two patients with acute pulpitis who were admitted to our hospital from September 2012 to March 2013 were randomly divided into two groups. The experimental group (n = 37) received nitrous oxide / The control group (n = 35) only underwent local anesthesia. Patients were evaluated using clinical anxiety and cooperative behavioral levels and WHO clinical pain assessment criteria. Data were subjected to rank sum test and χ2 test using SPSS 14.0 software package. Results: In the clinical anxiety and cooperative behavioral assessment, 86.5% in the experimental group and 42.9% in the control group were painless; 94.6% in the clinical pain rating group were painless and 68.6% in the control group were painless and the difference was significant (P <0.01). CONCLUSIONS: Good nociceptive and sedative effects of niacin / oxygen inhalation sedation for acute pulpitis treatment.
