Abstract

Background: Remimazolam (RM) is a novel ultra-short acting benzodiazepine. This study evaluates the safety of using RM for procedural sedation in the emergency department (ED) comparing its administration by registered nurse anaesthetists versus house officers in 1st year residency in emergency medicine and emergency medicine physicians without previous anaesthesiologic specialisation. Secondary aims were patient satisfaction and proportion of successful procedures.

Methods: This prospective study was performed at the ED at Aalborg University Hospital from 10 May through 20 August 2024. Five emergency medicine physicians (group 1) started administering RM to patients after completion of training and direct supervision. Results were compared to patients sedated by two registered nurse anaesthetists (group 2) who had been administering RM more than 50 times before study start. Time was recorded during sedation and a questionnaire filled out immediately after the patient had awakened. T-tests or Mann-Whitney U tests were used to compare groups. Proportions were calculated with chi-square (χ2) tests of proportion.

Results: In group 1, 53 patients were sedated by emergency medicine physicians, and in group 2, 50 patients were sedated by registered nurse anaesthetists. No or mild respiratory adverse effects were observed in 97% of patients in group 1 versus 100% in group 2. Procedural amnesia was 93% in group 1 versus 90% in group 2. Patients were safe to be left unsupervised after a median of 15 min in both groups. Procedural success was 92% in group 1 versus 100% in group 2.

Conclusions: Severe respiratory adverse effects after sedation were rare in both groups. Most patients had amnesia and adequate pain relief for the procedure. The use of RM by physicians without anaesthesiologic specialisation is considered a safe and effective alternative for procedural sedation in the ED.

Trial registration: The study was registered and approved as a quality study (ID 2017-011259) by the hospital administration.

雷马唑仑用于急诊科的程序性镇静:有效性和患者满意度的前瞻性研究。
背景:Remimazolam (RM)是一种新型超短效苯二氮卓类药物。本研究评估了在急诊科(ED)使用RM进行程序性镇静的安全性,比较了注册麻醉师护士与急诊医学第一年住院医师和没有麻醉专业背景的急诊医学医师对RM的管理。次要目标是患者满意度和手术成功率。方法:这项前瞻性研究于2024年5月10日至8月20日在奥尔堡大学医院急诊科进行。5名急诊医师(第一组)在完成培训和直接监督后开始对患者实施RM。结果与两名注册麻醉师护士镇静的患者(第二组)进行比较,这些患者在研究开始前已经给药50次以上。记录镇静期间的时间,并在患者醒来后立即填写一份调查问卷。采用t检验或Mann-Whitney U检验进行组间比较。采用χ2比例检验计算比例。结果:1组53例患者由急诊医师镇静,2组50例患者由注册麻醉师护士镇静。第1组97%的患者未观察到呼吸系统不良反应或轻度呼吸不良反应,而第2组为100%。1组的程序性失忆率为93%,2组为90%。在两组中位数为15分钟后,患者可以安全地无人监督。第1组手术成功率为92%,第2组为100%。结论:两组患者镇静后均未发生严重的呼吸不良反应。大多数患者在手术过程中都有健忘症和足够的疼痛缓解。在ed试验注册中,没有麻醉专业的医生使用RM被认为是一种安全有效的程序性镇静替代方案:该研究已被医院管理部门注册并批准为质量研究(ID 2017-011259)。

期刊介绍: The primary topics of interest in Scandinavian Journal of Trauma, Resuscitation and Emergency Medicine (SJTREM) are the pre-hospital and early in-hospital diagnostic and therapeutic aspects of emergency medicine, trauma, and resuscitation. Contributions focusing on dispatch, major incidents, etiology, pathophysiology, rehabilitation, epidemiology, prevention, education, training, implementation, work environment, as well as ethical and socio-economic aspects may also be assessed for publication.
