Oxygen saturation was recorded in 96 adults undergoing removal of third molar teeth in the dental surgery. Half the patients received local anaesthetic alone; the remainder received, in addition, intravenous midazolam. Patients receiving sedation sustained the greatest falls in oxygen saturation. However, in 10 out of 48 patients undergoing third molar removal with LA alone, oxygen saturations in the range of 93-89% were recorded. The results of this study suggest that all patients undergoing removal of third molars are at risk of hypoxia. Short episodes of hypoxia may be of little consequence in healthy patients, but in compromised patients early detection may avoid serious complications.
在牙科手术室对96名接受第三磨牙拔除术的成年人记录了血氧饱和度。一半患者仅接受局部麻醉；其余患者还接受了静脉注射咪达唑仑。接受镇静的患者血氧饱和度下降幅度最大。然而，在48名仅接受局部麻醉进行第三磨牙拔除术的患者中，有10名患者的血氧饱和度记录在93%-89%之间。本研究结果表明，所有接受第三磨牙拔除术的患者都有缺氧风险。短暂的缺氧发作对健康患者可能影响不大，但对身体状况不佳的患者，早期发现可避免严重并发症。
