目的观察笑气吸入清醒镇静法在阻生牙拔除术中的临床应用效果。方法 40例需拔除下颌第3磨牙的患者按随机数字表法分为实验组和对照组,每组20例;实验组采用笑气吸入清醒镇静加局麻法拔牙,对照组采用常规局麻法拔牙,记录两种方法的拔牙完成时间,收缩压(SBP)、舒张压(DBP)、心率(HR)和脉搏氧饱和度(SpO2)变化,并进行疼痛程度(VAS评分)和镇静程度(Ramsay评分)的观察。结果实验组拔牙时间缩短,SBP、DBP、HR、SpO2变化平稳,疼痛程度减轻,局麻和手术时VAS分别为(1.10±0.72)、(1.75±0.64);镇静程度增强,术前和术中Ramsay分别为(2.55±0.51)、(2.35±0.48),与对照组比较均有显著统计学差异(P<0.05)。结论笑气吸入清醒镇静法在阻生牙拔除术中具有安全、有效等特点,值得临床推广应用。
Objective To observe the effect of conscious inhalation of conscious smoker on the clinical application of impacted dental extraction. Methods 40 patients with mandibular third molars were randomly divided into experimental group and control group according to random number table method, 20 cases in each group. In the experimental group, clenched sedation plus local anesthesia was used in the experimental group, while the control group was treated with conventional local anesthesia The tooth extraction time, SBP, DBP, HR and SpO2 of the two methods were recorded and the pain degree (VAS score) and sedation level (Ramsay Score) of the observation. Results In the experimental group, the tooth extraction time was shortened, the changes of SBP, DBP, HR and SpO2 were stable and the pain was relieved. The VAS of local anesthesia and operation were (1.10 ± 0.72) and (1.75 ± 0.64) Ramsay were (2.55 ± 0.51) and (2.35 ± 0.48) respectively, which were significantly different from the control group (P <0.05). Conclusion Consciousness of inhalation of conscious smoother in impacted tooth extraction surgery is safe and effective, which is worthy of clinical application.
