The purpose of this study was to use 60% Lidocaine tape (LT) more effectively. Pain andanxiousness were compared for the Cubital Fossa (CF) and the distal end of the Dadius (DD), when venous puncture and cannulation in the vena cephalica were carried out after LT application. Healthy adult volunteers (Table 1) had LT applied on the surface of the skin with right vena cephalica either of CF or DD, and the veins were cannulated with an intravenous catheter (22G, 32mm long) after 60 minutes. State-anxiety was assessed by Face Anxiety Scale (FAS). Pain was evaluated with aVisual Analogue Scale (VAS). The FAS score of the DD group at entrance was significantly higher than that of the CF group. We thought that the volunteers expected pain at the venous puncture based on past experience. State-anxiety of the DD group was significantly stronger than the CF group in both venous puncture and cannulation. A strong anxiety state (scores of 4・5 of FAS) was observed only in the DD group (3/29 cases at puncture, 4/29 cases at cannulation) and not in the CF group. The VAS scores at puncture were 16.3±15.1 (mean±S. D.) in the CF group and 34.0±23.6 in the DD group. The VAS scores at cannulation were 11.9±13.8 in the CF group and 36.1±26.1 in the DD group. This indicates that the DD group pain was significantly stronger than that of the CF group at both puncture and cannulation. This result seems as could be expected as the peripheral side has more nocireceptors than the central side. Venous puncture and cannulation were carried out in CF or DD of the right vena cephalica after LT had been applied. Pain and anxiety of DD from the venous puncture and cannulation was stronger than those in CF. Accordingly, it was suggested that patient pain and anxiety associated with venous puncture and cannulation could be relieved by the application of LT at CF.
