Dexmedetomidine is increasingly being used as a sedative for monitored anesthesia care (MAC) with regional anesthesia. This literature review critiques 12 studies that used dexmedetomidine as the primary anesthetic. Study designs include prospective, retrospective case studies and randomized double-blind and randomized single-blind studies.
Twelve studies utilizing dexmedetomidine as the primary anesthetic that were found via electronic databases including CINAHL, Ovid, and MEDLINE. All studies were completed within the past 10 years and met inclusion and exclusion criteria.
The results of dexmedetomidine efficacy as a primary anesthetic agent for MAC procedures varied. There is significant evidence showing that dexmedetomidine is not an appropriate anesthetic for colonoscopies, though there were mixed results showing its efficacy in ENT and dental procedures. Despite that, dexmedetomidine has been shown to be successful in orthopedic, vascular, plastic, lithotripsy, and diagnostic procedures, though patients are at increased risk of recall.
Dexmedetomidine is an effective MAC anesthetic for specific procedures. Further research is needed to determine which specific procedures are appropriate for dexmedetomidine. Lastly, dexmedetomidine is more costly than current MAC anesthetics, making it difficult to justify its use.
右美托咪定越来越多地被用作区域麻醉下监护麻醉(MAC)的镇静剂。这篇文献综述对12项将右美托咪定用作主要麻醉剂的研究进行了批判性分析。研究设计包括前瞻性、回顾性病例研究以及随机双盲和随机单盲研究。
通过包括CINAHL、Ovid和MEDLINE在内的电子数据库检索到12项将右美托咪定用作主要麻醉剂的研究。所有研究均在过去10年内完成,并符合纳入和排除标准。
右美托咪定作为MAC手术主要麻醉剂的疗效结果各不相同。有大量证据表明右美托咪定不适用于结肠镜检查,不过在耳鼻喉科和牙科手术中其疗效结果不一。尽管如此,右美托咪定已被证明在骨科、血管、整形、碎石和诊断手术中是成功的,不过患者术中知晓风险增加。
右美托咪定是特定手术有效的MAC麻醉剂。需要进一步研究以确定哪些特定手术适合使用右美托咪定。最后,右美托咪定比目前的MAC麻醉剂成本更高,因此难以证明其使用的合理性。
