Hybrid operating theatres (OT) allow for simultaneous interventional radiology and operative procedures, serving as a one-stop facility for the treatment of severely injured patients. Several countries have adopted the use of the hybrid OT however their clinical impact in improving efficiency and quality of care remains unclear. This study systematically reviews the clinical impact of the hybrid OT for treatment of the severely injured. A literature review of the PubMed, Embase and Cochrane databases was performed to identify all published articles in English, from 1st January 2000 to 31st December 2020, reporting on the impact of a hybrid OT for severe trauma. Articles were also reviewed for references of interest. Five studies reporting the clinical impact of the hybrid OT, in a total of 951 patients, were shortlisted. All were cohort studies that compared patient outcomes in the hybrid OT versus a conventional group. Out of 3 studies that assessed timeliness to intervention, one reported shorter time associated with the hybrid OT, while the other two reported no difference. Mortality outcomes were reported in 4 studies and showed no significant difference associated with treatment in the hybrid OT. Two studies revealed shorter total procedure times associated with the hybrid OT. Two out of 3 studies that evaluated blood transfusion requirements reported decreased transfusion rates in the hybrid OT group. Only 1 study examined complication rates and demonstrated morbidity benefits associated with the hybrid OT. Establishment of a hybrid OT requires a significant capital investment as well as a highly functioning multi-disciplinary team. The cost–benefit ratio remains unclear. Future studies, preferably in the form of clinical trials, are required to evaluate its usefulness in improving timeliness to definitive haemorrhage control and outcomes in severe trauma.

混合手术室在严重创伤管理中的疗效的系统评价

混合手术室 (OT) 允许同时进行介入放射学和手术程序，作为治疗严重受伤患者的一站式设施。一些国家已经采用了混合 OT 的使用，但是它们在提高护理效率和质量方面的临床影响尚不清楚。本研究系统地回顾了混合 OT 治疗重伤者的临床影响。对 PubMed、Embase 和 Cochrane 数据库进行了文献综述，以识别 2000 年 1 月 1 日至 2020 年 12 月 31 日期间所有发表的英文文章，报告了混合 OT 对严重创伤的影响。还审查了文章以寻找感兴趣的参考资料。五项报告混合 OT 临床影响的研究，共 951 名患者，入围。所有这些都是队列研究，比较了混合 OT 与传统组的患者结果。在评估干预及时性的 3 项研究中，一项报告与混合 OT 相关的时间较短，而另外两项报告没有差异。4 项研究报告了死亡率结果，显示与混合 OT 治疗相关的无显着差异。两项研究表明，与混合 OT 相关的总手术时间更短。评估输血需求的 3 项研究中有两项报告称，混合 OT 组的输血率降低。只有 1 项研究检查了并发症发生率并证明了与混合 OT 相关的发病率益处。建立混合 OT 需要大量的资本投资以及功能强大的多学科团队。成本收益比仍不清楚。未来的研究，最好以临床试验的形式，需要评估其在改善严重创伤中明确出血控制和结果的及时性方面的有用性。
