起源于心脏的反射可以在正常生理学中发挥作用的想法可以追溯到19世纪60年代。直到20世纪50年代,这些反射,特别是Bezold-Jarisch反射(BJR),在很大程度上被视为药理学上的奇特之处,BJR研究的唯一实际应用是将藜芦碱作为降压药的临床应用。自19世纪60年代以来,人们已经知道注射微量(0.005毫克)藜芦碱或其纯生物碱成分(藜芦碱)会引起反射,导致血压和心率迅速下降,并伴随着呼吸暂停。这种“Von Bezold反射”被经典地定义为与呼吸停止有关,但最近被称为BJR,包括心动过缓、低血压和外周血管扩张的三联症。现在人们了解到,某些抑制性反射起源于心脏感觉受体,在心血管内稳态中发挥作用。这些受体的一个子集被不同的刺激激活会增加副交感神经系统的活性,抑制交感神经的活性,并负责诱发BJR。一些麻醉学家提出,BJR可能解释了区域麻醉技术中报告的心血管衰竭。这篇综述着重于BJR的生理学以及它在一些临床情况下可能的生理学作用。它也提供了关于这种反射在区域麻醉中的有限相关性的讨论。由于缺乏这方面的数据,临床管理的主题将不会被讨论,但对未来的实验方向提供了建议。
THE idea that reflexes originating in the heart can play a role in normal physiology dates to the 1860s. Until the 1950s, these reflexes, and the Bezold–Jarisch reflex (BJR) in particular, were regarded largely as pharmacological curiosities with the only practical application of the study of the BJR being the clinical use of a veratrum alkaloid as an antihypertensive agent. Since the 1860s, it had been known that injection of minute amounts (0.005 mg) of veratrine or its pure alkaloid components (veratrum) initiates a reflex which causes a rapid fall in blood pressure and heart rate in association with apnea. This “Von Bezold reflex” was classically defined in association with arrest of breathing, but more recently, it has been called the BJR and includes the triad of bradycardia, hypotension, and peripheral vasodilation. It is now understood that certain inhibitory reflexes, which have origin with cardiac sensory receptors, play a role in cardiovascular homeostasis. Activation of a subset of these receptors by diverse stimuli increases parasympathetic nervous system activity, inhibits sympathetic activity and is responsible for eliciting the BJR. Some anesthesiologists have suggested that the BJR may explain cardiovascular collapse reported during regional anesthesia techniques. This review focuses on the physiology of the BJR and its possible physiologic role in a number of clinical situations. It also provides discussion of the limited relevance of this reflex in regional anesthesia. The topic of clinical management will not be addressed given the paucity of data on this matter, but suggestions for future experimental direction are offered.
