笑气/氧气混合吸入镇静镇痛在拔牙术中的应用

Abstract

Abstract: 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 extraction, there was statistically significant difference in sedation analgesia, vital signs assessments（P＜0.05）. Conclusion　Nitrous oxide / oxygen inhalation conscious 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.
