摘要
目的 探讨手背静脉穿刺时疼痛程度最低的最佳部位 ,减轻患者的痛苦。方法 解剖了 1 2例 2 4侧成人手背标本 ,观察手背静脉与皮神经的关系 ,按照手背静脉及皮神经的分布规律 ,将手背分为 1、2、3区 ,指导临床进行 2 980例次手背静脉穿刺 ,用简化 Mc Gill疼痛评分表中现有疼痛强度 (PPI)进行评分。结果 解剖发现桡骨茎突、尺骨茎突及第三掌骨头所形成的三角形区域内神经分布稀疏 ,神经与静脉呈交叉关系 ,临床应用证实在此区域内静脉穿刺疼痛分值明显低于其它区域 (P<0 .0 1 )。结论 桡骨茎突、尺骨茎突及第三掌骨头所形成的三角形区域可称为“乏神经区”,可作为手背静脉穿刺时首选部位 ,其它区域的静脉穿刺可根据皮神经的体表投影来确定进针点及进针深度 。
Objective [WT6BZ]To relieve the pain of venepuncture in the dorsum of the hand.[WT6HZ]Methods [WT6BZ]Twelve adult cadaveric hands were carefully dissected to study the relationship between cutaneous nerves and subcutaneous veins in the dorsum of the hand,and 2980 times venepuncture were performed in 3 areas of the dorsum manus divided according to the nerve distribution and the pain during the venepuncture was assessed by present pain intensity (PPI) of the short from McGill pain Questionnaire.[WT6HZ]Results [WT6BZ]There were few nerve branches which only crossed beneath veins not accompanied closely with the veins in the triangular area formed by styloid process of ulna,styloid process of radius and the head of the third metacarpal bone,the values of PPI were statistically lower in the triangular area than in other ones ( P <0.01).[WT6HZ]Conclusions [WT6BZ]The triangular area might be called nerve lacking area and it is the proper location for painless venepuncture in the dorsum of the hand.In the other area,however,it is necessary to choose the venepuncture point on the site of the vein without accompanying nerve and to avoid the point where nerve crossed the vein.
