超声可视化血管穿刺技术在血管外科临床教学中的应用

Application of ultrasound visual vascular puncture technology in clinical teaching of vascular puncture technology

目的 本研究通过探索超声可视化血管穿刺技术在血管穿刺技术临床教学中的应用,以期提高血管穿刺的教学效果。方法 选择2021年4月—2022年4月于蚌埠医学院医院第一附属医院血管外科进行实践教学的本科实习医生、规培医生70人作为研究对象。先对其进行常规的入科宣教及血管穿刺技术的培训,再使用随机数字表法将其分为应用超声可视化血管穿刺技术进行血管穿刺教学组(观察组,35人)、常规血管穿刺技术教学组(对照组,35人)。分析比较2组学生血管穿刺完成的时间、穿刺成功率、发生并发症情况等,评估教学效果。结果 2组学生均成功完成血管穿刺操作,观察组学生自局麻开始穿刺针进入目标血管的时间、血管穿刺完成的总时间、并发症发生率均少于对照组[(14.06±1.98) min vs.(17.84±2.07) min;(23.51±3.49) min vs.(28.64±2.94) min;5.71%(2/35)vs.25.71%(9/35)],差异均有统计学意义(均P<0.05)。结论 超声可视化血管穿刺技术在血管外科血管穿刺临床教学中的应用效果良好,相较传统的穿刺教学方法效率更高、并发症发生少、教学效果更好、安全性更高,值得在血管穿刺教学中广泛应用。

Objective To explore the application of ultrasound visual vascular puncture technology in clinical teaching of vascular puncture technology,and hope to improve the teaching effect of vascular puncture.Methods A total of 70 undergraduate interns and standardized trained doctors in vascular surgery of the First Affiliated Hospital of Bengbu Medical College from April 2021 to April 2022 were selected as the research objects.They were first trained in routine admission education and vascular puncture techniques,and then divided into a vascular puncture teaching group applying ultrasound visual vascular puncture technology(observation group,35 people),and a conventional vascular puncture technology teaching group(control group,35 people)using the random number method.The teaching effect of the two groups was evaluated by analyzing the completion time of blood vessel puncture,the successful rate of puncture,and the indicators of complications of the two groups of students.Results Both groups of students successfully completed the vascular puncture operation.The time of puncture needle entering the target vessel,the total time of vascular puncture completion and the incidence of complications in the observation group were less than those in the control group[(14.06±1.98)min vs.(17.84±2.07)min;((23.51±3.49))min us.(28.64±2.94)min;5.71%(2/35)vs.25.71%(9/35)],the differences were statistically significant(all P<0.05).Conclusion The application of ultrasound visual vascular puncture technology in clinical teaching of vascular surgery is effective.Compared with the traditional puncture teaching method,it has higher efficiency,fewer complications,better teaching effect and higher safety,and should be widely used in vascular puncture teaching.
