摘要：
Objective To investigate the application of Vein Infrared Imaging instrument in the treatment of medical patients with difficulty of vein-detaining needle. Methods A total of 116 cases of patients with difficulty of vein-detaining needle were admitted to Peking Union Medical College Hospital International Medical Service Department from June 2015 to May 2016. These participants were divided into vein imaging and conventional puncture group by the punctures method, 58 cases in each group. Vein imaging group applied vein imaging device in the whole process of venous indwelling needle, including vascular assessment before operation, real-time imaging and confirmation, the control group used conventional technology in peripheral venous catheter. The success rate of vein-detaining needle, operation time, puncture tube material cost, the incidence rate of venous indwelling needle complications were compared between two groups of patients. Results One-time success rate of vein imaging group reached 72.4% (42/58), puncture success rate reached 93.1% (54/58), higher than in conventional puncture group, which was 48.3% (28/58), 67.2% (39/58),the difference between the two groups had statistical significance(χ2=7.061, 10.629,P<0.05). Conventional puncture group 's operation time was (8.4±4.2) min,and puncture tube material cost was(123.37±62.20)yuan;vein imaging group respectively were (3.5±1.2) min, (67.50±24.82) yuan, the difference between the two groups had statistical significance (t=5.410, 4.057, P<0.05). Conventional puncture group's rate of complications was 41.4%(24/58), and vein imaging group was 17.2%(10/58), the difference between the two groups had statistical significance (χ2=8.155,P=0.004). Conclusions Application of vein infrared imaging instrument is a practical, safe and rapid method of vein-detaining needle, which can improve the work efficiency of nurses, and have more advantages in the treatment of patients with difficulty of vein-detaining needle.%目的 探讨静脉显像仪下静脉留置针穿刺技术在内科困难置管患者中的应用.方法 选取2015年6月至2016年5月北京协和医院国际医疗部内科收治的外周静脉置管困难的患者116例,按照穿刺方法不同分为静脉显像组和常规穿刺组,每组58例,静脉显像组将静脉显像仪应用于静脉留置针置入全过程,包括操作前血管的评估、操作时的实时显像及操作后的确认;常规穿刺组采用常规技术置入外周静脉导管.对2组患者静脉留置针的一次穿刺成功率、操作时间、穿刺耗材费用、静脉留置针并发症的发生率进行比较.结果 静脉显像组一次性穿刺成功率72.4%(42/58),穿刺成功率93.1%(54/58),均高于常规穿刺组的48.3%(28/58)、67.2%(39/58),2组比较差异有统计学意义(χ2=7.061、10.629,P<0.05).常规穿刺组置管操作时间(8.4±4.2)min,耗材费用(123.37±62.20)元,静脉显像组分别为(3.5±1.2)min、(67.50±24.82)元,2组比较差异有统计学意义(t=5.410、4.057,P<0.05).常规穿刺组并发症总发生率为41.4%(24/58),静脉显像组为17.2%(10/58),2组比较差异有统计学意义(χ2=8.155,P=0.004).结论 静脉显像仪下静脉留置针穿刺术是一种实用、安全、快速的置管方法,提高了护士的工作效率,在内科难置管患者静脉治疗中更突显其优势.
