We previously reported that cubital venous pressure (Pv) tended to increase initially, but this was followed by a drop in a dose-dependent response after intravenous lidocaine administration in subjects with various diseases. In this study we examined whether Pv responses after small-dose intravenous lidocaine administrations are related to the stimulating effect of lidocaine on vascular smooth muscle (VSM). In 5 subjects free of cardiovascular disease, Pv increased slightly with decreased pulsations after a 10 mg dose (p&lt;0.01) with no change in central venous pressure. In the cinephlebographic test performed on 2 healthy volunteers, Pv increased during recovery from proximal venoconstriction caused by an injection of contrast medium mixed with 10 mg lidocaine. In 9 subjects with cardiovascular disease, deltaPv spread in the same directions (+ or -) after 5 and 10 mg drug administrations. In 6 of those tested with both drug doses, deltaPv had positive means and no significant difference was observed. Thus, Pv responses after small-dose lidocaine administrations are consistent with neither the stimulating effect of lidocaine nor with a dose-dependent response. They could be attributed to the spasmolytic effect of lidocaine on the basal tone of VSM, which could be modulated by disease conditions.
