目的:为科学合理利用手背静脉、减轻患者痛苦,针对不同人群使用不同穿刺准备方法提高远端浅静脉一次性穿刺成功率,探讨静脉穿刺方法在临床中的实用性。方法:两种穿刺方法均选择手背下1/3掌指关节附近的血管,第一种方法确定穿刺部位后松开止血带消毒再扎上止血带消毒待干进针;第二种方法是确定穿刺部位后消毒待干进针。结果:根据比较两者血管充盈度,一次性穿刺成功率、患者疼痛强度等方面,得到适合不同人群的穿刺方法。差异有统计学意义。结论:对于皮肤容易敏感患者,第一种穿刺能有效提高穿刺成功率;对于老年人,第二种穿刺方法能有效提高穿刺成功率。
OBJECTIVE: To improve the success rate of one-time puncture of distal superficial venous puncture for different populations by using different types of puncture preparation in order to scientifically and reasonably utilize the dorsal veins, and to explore the practicability of venipuncture in clinical practice. Methods: Both methods of puncture select the blood vessels around the metacarpophalangeal joints in the back of the hand. The first method is to determine the puncture site and release the tourniquet disinfection, and the tourniquet is sterilized to be dried into the needle. The second method is to determine After the puncture site to be disinfected into the needle. Results: According to the comparison of the vascular filling degree, the success rate of one-time puncture and the pain intensity of the patients, the puncture method suitable for different groups was obtained. The difference was statistically significant. Conclusion: The first puncture can effectively improve the puncture success rate in patients with sensitive skin and the second puncture method can effectively improve puncture success rate in the elderly.
