介绍本研究评估是否轻拍增强血管扩张的个人静脉是相对难以触诊。材料与方法20名患者（4男16女，年龄19-22岁），即使在止血带应用后，皮肤静脉也相对难以触及。在上臂止血带充气的情况下进行有/无叩击（5 s内10次）的交叉试验。通过超声检查评估静脉横截面积、静脉深度和覆盖皮肤的高度来评价血管舒张。还测量了静脉触诊评分。通过模拟估计改进的程度。结果60%的受试者“有时”或“经常”经历静脉穿刺失败。穿刺后，静脉横截面积显著增加（对照组为14.6 +/- 9.12 mm（2），穿刺组为15.2 +/- 9.79 mm（2）），静脉深度显著降低（对照组为4.57 +/- 2.31 mm，穿刺组为4.23 +/- 2.41 mm）。使用这些值进行的模拟研究表明，敲击可将静脉穿刺的纵向和纵向成功范围增加5- 6%。结论在这项研究中，轻拍增强了相对难以触及的皮肤静脉的血管舒张。各种血管扩张方法的有效性可以通过改善的估计进行比较。
Introduction This study evaluated whether tapping enhances vasodilation in individuals with veins that are relatively difficult to palpate. Materials and Methods Twenty participants (4 men and 16 women, aged 19-22 years) with cutaneous veins that were relatively difficult to palpate even after tourniquet application were recruited. A crossover trial with/without tapping (10 times in 5 s) was performed under tourniquet inflation on the upper arm. Vasodilation was evaluated by venous cross-sectional area, depth of the vein, and elevation of the overlying skin by ultrasonography. Venous palpation scores were also measured. The degree of improvement was estimated by simulation. Results In total, 60% of participants "sometimes" or "often" experienced unsuccessful venipuncture. After the tapping procedure, the venous cross-sectional area significantly increased (14.6 +/- 9.12 mm(2) for control and 15.2 +/- 9.79 mm(2) for tapping) and venous depth significantly decreased (4.57 +/- 2.31 mm for control and 4.23 +/- 2.41 mm for tapping). A simulation study using these values suggested that tapping increased the longitudinal and crosswise successful ranges of venipuncture by 5-6%. Conclusions Tapping in this study enhanced the vasodilation of cutaneous veins that are relatively difficult to palpate. The effectiveness of various vasodilation methods may be compared through the estimation of improvement.
