Objective: To study the efficacy of nitrous oxide inhalation in painless induced abortion. Methods: Two hundred and sixty women who voluntarily demanded termination of early pregnancy were randomly divided into observation group (50% inhalation of nitrous oxide during the operation), control group (no drug during the operation), and intraoperative and postoperative reaction. Results: The intraoperative pain in the observation group was significantly lower than that in the control group. No abortion syndrome occurred in the observation group. There was less bleeding during operation and no significant difference in preoperative, postoperative, blood pressure, heart rate and oxygen saturation. Conclusion: The inhalation method of nitrous oxide is simple and safe, which can effectively alleviate the pain of induced abortion in pregnant women
