Methods: One hundred and eighteen outpatients undergoing endoscopy with the same doctor and the same model endoscopy. The patients were given midazolam 0.15mg/kg intramuscular.The examination began after 30 min. The sedative score (OAA/S) and vital signals (MAP, HR, SPO2)were observed during and after endoscopy. Evaluate the degree of the patients' amnesia and the satisfaction of doctor and patients. Results: All patients had good tolerance with endoscopy. The patients had resporise to command language and could talk with the doctor and cooperate during examination. No significant changes were fond with MAP, HR and SpO2. The adverse reaction, such as nausea, suffocate and windy, was decreased significantly. Respiratory depression was none. Flumazenil didn't affect anterograde amnesia of midazolam. Conclusion: Miidazolam 0.15mg/kg intramuscular in endoscopy not only decreases pain of patients, offers steady hemodynamic, but also brings about amnesia effect after examination, hence safeguards body and mind.It is suitable for conscious sedative in endscopy. Key Words: Midazolam; Endoscopy;Conscious sedation 内镜检查时患者往往有明显不适感(恶心、屏气、咽部不适、腹胀、腹疼等),甚至躁动,难以合作,给内镜检查带来困难。本试验拟研究咪达唑仑在内镜检查中的清醒镇静效果及对呼吸循环的影响。 资料与方法 118例做内镜检(41例纤维结肠镜,73例内镜逆行性胰胆管造影,4例纤维胃镜)的患者,ASA1~2级,男51例,女67例,年龄(56.90±5.97)kg。 患者入室后用惠普监测仪监测血压、心率、脉搏氧。2%利多卡因表面麻醉后肌肉注射咪达唑仑0.15mg/kg,30分钟后进行检查。于下列7个时间点:入室、肌注后10min、肌注后20min、进镜、进镜后10min、进镜后20min、进镜后30min,记录患者血压、心率、脉氧,观察患者耐受状况和合作程度并采用国际标准化方式OAA/S进行镇静分级与评分。检查结束后随机选择20例患者静脉注射氟马西尼每次0.1mg直至OAA/S评分达5分。次日询问患者对检查的记忆及满意程度,记忆缺失分为无记忆(即不记得检查操作),有部分记忆(即经提醒可记忆起部分检查过程)。 |
