OBJECTIVE To evaluate the efficacy and safety of intravenous (i.v.) thiamylal in pediatric magnetic resonance imaging (MRI) sedation. METHODS Infants and children from 1 month up to 8 years of age who underwent MRI in our hospital between April 2017 and March 2019 were included in this prospective observational study. Initial dose of 2 mg/kg thiamylal was given intravenously; however, additional doses were administered as needed. MRI was performed after adequate sedation was achieved. The primary endpoint was the success rate of MRI, while secondary endpoints were adverse events related to sedation, time to sedate, recovery time, and the dose of thiamylal. RESULTS A total of 118 patients were included in the analysis with median age and weight of 31.5 months (14.0-56.8 months) and 12.6 kg (9.5-15.7 kg), respectively. The success rate of MRI was 96.6% (114/118), and the median dose of thiamylal per body weight was 3.6 (2.8-4.0) mg/kg. The median time from the first dose of thiamylal to MRI was 7 min (4-10 min) and that from the end of MRI scanning to the confirmation of emergence was 8 min (5-25 min). Adverse events encountered included respiratory arrests (n = 3) and reduction in oxygen saturation (SpO2; n = 9). There were no significant differences in the age, dose of thiamylal, sex, body weight, the American Society of Anesthesiologists physical status, and neurological abnormalities between the groups with and without respiratory complications. CONCLUSION This study demonstrated an adequate efficacy and safety of i.v. thiamylal, with rapid sedation and patient recovery.

静脉注射硫醛酸在儿科磁共振成像程序镇静中的有效性和安全性

目的 评估静脉注射 (iv) 硫胺醛在儿科磁共振成像 (MRI) 镇静中的有效性和安全性。方法 2017年4月至2019年3月期间在我院接受MRI检查的1个月至8岁婴幼儿纳入本前瞻性观察研究。初始剂量为 2 mg/kg 硫胺醛静脉给药;然而,根据需要给予额外剂量。充分镇静后进行MRI检查。主要终点是 MRI 的成功率,而次要终点是与镇静、镇静时间、恢复时间和硫醛酸剂量相关的不良事件。结果 共有 118 名患者被纳入分析,中位年龄和体重分别为 31.5 个月(14.0-56.8 个月)和 12.6 kg(9.5-15.7 kg)。MRI的成功率为96。6% (114/118),每体重中硫醛的中位剂量为 3.6 (2.8-4.0) mg/kg。从第一剂硫醛酸到 MRI 的中位时间为 7 分钟(4-10 分钟),从 MRI 扫描结束到确认出现的时间为 8 分钟(5-25 分钟)。遇到的不良事件包括呼吸停止(n = 3)和氧饱和度降低(SpO2;n = 9)。有和无呼吸系统并发症的组在年龄、硫醛酸剂量、性别、体重、美国麻醉医师协会身体状况和神经系统异常方面没有显着差异。结论 本研究证明了 iv 硫胺醛的足够疗效和安全性,具有快速镇静和患者康复的作用。从第一剂硫醛酸到 MRI 的中位时间为 7 分钟(4-10 分钟),从 MRI 扫描结束到确认出现的时间为 8 分钟(5-25 分钟)。遇到的不良事件包括呼吸停止(n = 3)和氧饱和度降低(SpO2;n = 9)。有和无呼吸系统并发症的组在年龄、硫醛酸剂量、性别、体重、美国麻醉医师协会身体状况和神经系统异常方面没有显着差异。结论 本研究证明了 iv thiamyalal 的足够疗效和安全性,具有快速镇静和患者康复。从第一剂硫醛酸到 MRI 的中位时间为 7 分钟(4-10 分钟),从 MRI 扫描结束到确认出现的时间为 8 分钟(5-25 分钟)。遇到的不良事件包括呼吸停止(n = 3)和氧饱和度降低(SpO2;n = 9)。有和无呼吸系统并发症的组在年龄、硫醛酸剂量、性别、体重、美国麻醉医师协会身体状况和神经系统异常方面没有显着差异。结论 本研究证明了 iv thiamyalal 的足够疗效和安全性,具有快速镇静和患者康复。遇到的不良事件包括呼吸停止(n = 3)和氧饱和度降低(SpO2;n = 9)。有和无呼吸系统并发症的组在年龄、硫醛酸剂量、性别、体重、美国麻醉医师协会身体状况和神经系统异常方面没有显着差异。结论 本研究证明了 iv thiamyalal 的足够疗效和安全性,具有快速镇静和患者康复。遇到的不良事件包括呼吸停止(n = 3)和氧饱和度降低(SpO2;n = 9)。有和无呼吸系统并发症的组在年龄、硫醛酸剂量、性别、体重、美国麻醉医师协会身体状况和神经系统异常方面没有显着差异。结论 本研究证明了 iv thiamyalal 的足够疗效和安全性,具有快速镇静和患者康复。
