BACKGROUND
Hemodynamic perturbations in spine surgeries are predominantly reported in cervical and thoracic level procedures. The literature related to negative cardiovascular changes (decrease of heart rate and blood pressure) in lumbar spine procedures is still scarce and only highlighted in few case reports/letters until now.
METHODS
With the help of a systematic literature review with predefined criteria, we, therefore, examined and synthesized here the probable underlying common cause of these hemodynamic disturbances in lumbar spine surgeries. Data aggregation to a model was done by a case survey method and established by a cause-effect relationship.
RESULTS
There are only 5 cases that met our strict predefined criteria and that were aggregated to an emergent model of an autonomous reflex arc.
CONCLUSION
This review and consecutive data aggregation provides, for the first time, a concept of spinal cardiac reflex in lumbar spine surgeries.
背景
脊柱手术中的血流动力学扰动主要在颈椎和胸椎手术中被报道。迄今为止，关于腰椎手术中负面心血管变化（心率和血压降低）的相关文献仍然稀少，仅在少数病例报告/信函中有所提及。
方法
因此，借助具有预定义标准的系统文献综述，我们在此检查并综合了腰椎手术中这些血流动力学紊乱可能的潜在共同原因。通过病例调查方法将数据汇总到一个模型中，并通过因果关系来确立该模型。
结果
仅有5例符合我们严格的预定义标准，并被汇总到一个自主反射弧的紧急模型中。
结论
本综述及后续的数据汇总首次提出了腰椎手术中脊髓心脏反射的概念。
