The present study was undertaken to investigate the effects of vasopressor substances contained in local anesthetics in dentistry. The results obtained indicate substantial cardiac activity of these anaesthetics, as shown by electrocardiographic (EKG) tracings carried out on patients before and after anesthetization. The vasoconstrictors, adrenaline or noradrenaline, resulted at times in slight cardiac lesions which could not be observed clinically. Careful anamneses could avoid such situations.
本研究旨在调查牙科局部麻醉剂中所含血管加压物质的作用。所得结果表明，这些麻醉剂具有显著的心脏活性，麻醉前后对患者进行的心电图（EKG）描记显示了这一点。血管收缩剂肾上腺素或去甲肾上腺素有时会导致轻微的心脏损伤，临床上无法观察到。仔细询问病史可以避免这种情况。
