目的:在生命末期,一些难治性痛苦的患者需要深度持续镇静。基于药理学性质,我们假设在这些特殊情况下,氧化钠可能通过防止镇静减轻而提供优势,这是咪达唑仑(目前推荐的药物)所报道的局限性。本试验旨在比较氧化钠和咪达唑仑在生命末期深度持续镇静的疗效。方法:这项单中心、单盲、平行组、随机试验测试了氧酸钠与咪达唑仑对这一适应症的疗效。主要结局是治疗成功,定义为达到和维持里士满激动-镇静量表小于或等于-4的能力。入住急性姑息治疗病房的患者被随机分配接受一种标准剂量的氧化钠,随后进行维持治疗或咪达唑仑的滴定剂量,随后进行维持治疗。患者对小组分配不知情。采用意向治疗法进行分析。本研究已在ClinicalTrials.gov注册(NCT05085873)。结果:在2021年10月14日至2023年10月9日期间,纳入了22例患者。氧化钠组的治疗成功率为100% (95% CI 71.5%至100%),而咪达唑仑组的治疗成功率为0% (95% CI 0%至28.5%)。结论:这项首次将咪达唑仑与另一种镇静剂进行比较的临终随机对照试验表明,氧化钠可能提供更稳定的持续深度镇静,镇静深度波动更小。这些发现支持在这种特殊情况下改善患者舒适度的潜力。
期刊介绍:
Published quarterly in print and continuously online, BMJ Supportive & Palliative Care aims to connect many disciplines and specialties throughout the world by providing high quality, clinically relevant research, reviews, comment, information and news of international importance.
We hold an inclusive view of supportive and palliative care research and we are able to call on expertise to critique the whole range of methodologies within the subject, including those working in transitional research, clinical trials, epidemiology, behavioural sciences, ethics and health service research. Articles with relevance to clinical practice and clinical service development will be considered for publication.
In an international context, many different categories of clinician and healthcare workers do clinical work associated with palliative medicine, specialist or generalist palliative care, supportive care, psychosocial-oncology and end of life care. We wish to engage many specialties, not only those traditionally associated with supportive and palliative care. We hope to extend the readership to doctors, nurses, other healthcare workers and researchers in medical and surgical specialties, including but not limited to cardiology, gastroenterology, geriatrics, neurology, oncology, paediatrics, primary care, psychiatry, psychology, renal medicine, respiratory medicine.
