氧化亚氮/氧气混合气吸入镇静镇痛在口腔门诊小手术中的临床应用研究

Clinical application of Nitrous oxide/oxygen gas mixture for inhalation sedation and analgesia in oral minor surgery of outpatients

目的观察比较氧化亚氮/氧气混合气吸入镇静镇痛在口腔门诊小手术中的临床应用情况。方法对口腔颌面外科门诊就诊的患者,分别采用氧化亚氮/氧气混合气吸入配合局麻和单纯局部麻醉,进行治疗。通观察患者心率,血氧饱和度等临床指标的变化。结果 2组患者在整个手术过程中的心率及血氧饱和度的变化情况,注射局麻时的VAS疼痛评分比较,术中疼痛程度和镇静程度比较,差异均有显著性。结论氧化亚氮/氧气混合气吸入配合局麻具有安全、有效的特点,对于复杂牙拔除、阻生牙拔除等口腔门诊小手术具有很好的辅助效应。

Objective To observe clinical application of nitrous oxide/oxygen gas mixture for inhalation sedation and analgesia in oral minor surgery of outpatients.Methods Patients of oral and maxillofacial surgery clinic respectively inhaled nitrous oxide/oxygen gas mixture with local anesthesia and simple local anesthesia for treatment.Observe clinical indicators like heart rates and oxygen saturation changes.Results There were significant differences in heart rates,oxygen saturation changes,the VAS pain scores with injection of local anesthesia,degrees of pain and sedation in the surgery between the two groups of patients throughout the treament.Conclusions Nitrous oxide/oxygen gas mixture inhalation with local anesthesia is safe and effective for extraction of complex teeth,impacted teeth and other minor surgeries in stomatological clinics.
