经肝动脉介入诊疗模拟系统在教学中的应用评价

Transhepatic artery interventional catheterization simulation system: its application in clinical teaching

目的评价经肝动脉介入诊疗模拟系统在教学中的应用价值。方法测试者在模拟系统用RH肝管完成经肝动脉插管初试后记录时间,通过模拟系统练习30次后,进行终试并记录时间,将初试及终试时间进行统计学分析,测试结束后填写调查问卷。结果共有43位测试者参加实验,全部完成初试、插管练习和终试,均未出现错误操作,总合格率为100%。初试和终试总用时分别为(384.70±200.4)s和(214.93±115.4)s,两者间差异有统计学意义(P<0.01)。练习后肝动脉插管操作所用时间较练习前显著缩短。分析调查问卷表明,测试者普遍认为通过经肝动脉介入诊疗教学模拟系统训练可提高技术操作水平。结论经肝动脉介入诊疗教学模拟系统对提高初学者操作水平及熟练程度有一定应用价值。

Objective To discuss the application of transhepatic artery interventional catheterization simulation system in clinical teaching. Methods The participant was asked to complete the initial test according to hepatic artery catheterization procedure, and the time used by the participant was recorded. After practicing on the simulation system for 30 times, the participant was asked to perform the terminal test and the time used by him was recorded again. The initial and terminal test time was statistically analyzed. Finally, participants were asked to complete the questionnaire form to determine the subjects＇ self-assessment of their performance. Results A total of forty-three subjects fully participated in the study. All the subjects made no mistakes in performing the procedure. The mean time of initial and terminal test was （384.70±200.4） seconds and （214.93 ± 115.4） seconds, respectively. The difference in used time between the initial and terminal test was statistically significant （P 〈 0.01 ）. After practicing on the simulation system for 30 times, the used time for hepatic artery catheterization was significantly reduced. The analysis of the questionnaire indicated that all the participants firmly believed that after practicing on the simulation system their skill in interventional manipulation was markedly improved. Conclusion Teaching training with transhepatic artery interventional simulation system is of great value in improving the beginner＇s interven- tional manipulation skill.（J Intervent Radiol, 2012, 21 ： 869-872）
