药物成份或治疗方案详述: |
本研究为一项前瞻性、单中心、开放标签、随机对照试验。本研究纳入90例年龄1月-1岁,ASAⅡ-Ⅲ级,计划行MRI检查需镇静的婴儿。采用随机数字表法将符合条件的患儿分为3组,右美托咪定联合水合氯醛组(DC组)、右美托咪定联合咪达唑仑组(DM组)与右美托咪定联合艾司氯胺酮组(DE组),每组30例。三组患儿均在检查前40-50分钟给予镇静药物,用药方案如下: 1.DC组(n=30):右美托咪定2ug/kg滴鼻+50mg水合氯醛口服。 2.DM组(n=30):右美托咪定2ug/kg滴鼻+0.5mg咪达唑仑口服。 3.DE组(n=30):右美托咪定2ug/kg滴鼻+1.5mg艾司氯胺酮滴鼻。 用药后记录患儿具体用药时间。随后根据MOAA/S评分判断患儿状态,MOAA/S≤2分即可开始等待扫描,用药后成功完成扫描且无需补救定义为首次诱导成功。若检查前5分钟MOAA/S评分仍>2分,或检查途中患儿苏醒或出现身体扭动导致无法继续检查,定义为首次诱导失败。所有患儿在用药后由于各种原因(严重不良反应、家长拒绝补救和改期检查等)导致没有完成检查,均定义为镇静失败。患儿完成检查后入镇静恢复室进行监测和复苏。Aldrtete苏醒评分≥8分,定义为苏醒,并记录苏醒时间。当患儿Aldrtete苏醒评分≥9分且生命体征平稳,进食后无不良反应,经麻醉医生评估后准许其离开医院。护士在24小时内对所有患儿完成一次电话随访并进行家长满意度调查。 |

Description for medicine or protocol of treatment in detail: |
This study is a prospective, single-center, open-label, randomized controlled trial. A total of 90 infants aged 1 month to 1 year, classified as ASA physical status II–III, scheduled for magnetic resonance imaging (MRI) requiring sedation, were enrolled. Eligible patients were randomly assigned to one of three groups using a random number table: the dexmedetomidine combined with chloral hydrate group (DC group), the dexmedetomidine combined with midazolam group (DM group), and the dexmedetomidine combined with esmolamine ketamine group (DE group), with 30 patients in each group. All patients received sedative medications 40–50 minutes prior to the MRI scan according to the following protocols: 1. DC group (n = 30): Dexmedetomidine 2 μg/kg via nasal drop + oral chloral hydrate 50 mg. 2. DM group (n = 30): Dexmedetomidine 2 μg/kg via nasal drop + oral midazolam 0.5 mg. 3. DE group (n = 30): Dexmedetomidine 2 μg/kg via nasal drop + esmolamine ketamine 1.5 mg via nasal drop. The exact time of drug administration was recorded. Subsequently, patient status was assessed using the MOAA/S score; initiation of scanning was permitted when the MOAA/S score was <=2 points. Successful completion of the scan without rescue intervention after drug administration was defined as first successful induction. Failure of first induction was defined as either a MOAA/S score >2 points within five minutes before scanning or intra-scan awakening or body movement leading to interruption of the procedure. Any patient who failed to complete the scan due to various reasons after medication—such as severe adverse events, parental refusal for rescue or rescheduling—was defined as sedation failure. After completing the scan, all patients were transferred to a post-sedation recovery room for monitoring and recovery. Aldrete wake-up score ≥8 points was defined as emergence from sedation, and time of emergence was recorded. When Aldrete wake-up score reached ≥9 points and vital signs remained stable, with no adverse reactions after oral intake and approval by an anesthesiologist, patients were permitted to be discharged from hospital. Nurses conducted telephone follow-ups and parent satisfaction surveys within 24 hours after discharge for all patients. |
