Abstract: Objective　To explore the application of the clinical teaching method of femoral venipuncture catheterization in oncology department and improve the mastery of femoral venipuncture catheterization for clinical rotation training beginners. Methods　Twenty-eight interns for training in rotation in Oncology Center, The First Affiliated Hospital of Guangzhou University of Chinese Medicine from February 2020 to February 2022 were selected. The clinical teaching of femoral venipuncture catheterization was carried out. The success rate of femoral venipuncture catheterization in the teaching process was counted, and the experience and lessons of femoral venipuncture catheterization were shared and summarized. χ² tests and ANOVA were applied. Results　The first, second, and third year graduates did the puncture during the teaching process (3.62±0.92) times, (3.83±1.19) time, and (4.25±1.49) times, respectively, with no statistical difference (F=0.55, P=0.582). The first, second, and third year graduates spent (5.75±2.77) min, (6.17±3.21) min, and (3.88±1.64) min on successful catheterization, respectively, with no statistical difference (F=1.79, P=0.188). The success rates of catheterization of the first, second, and third year graduates when they left the center were 50%(4/8),75.0%(9/12),and 62.5%(5/8), respectively, with no statistical difference (χ²=1.32, P=0.516). The proportions of mastering puncture site localization of the first, second, and third year graduates were 87.5%(7/8),91.7%(11/12),and 100.0%(8/8), respectively, with no statistical difference (χ²=0.99, P=0.61). Conclusions　Femoral venipuncture catheterization is widely used in patients with tumors. Because of its difficulty and risk, it requires higher proficiency of the operators. According to the results of teaching and training for medical students of different grades, the overall effect of the clinical teaching method of puncture technique is basically the same, which is helpful to guide beginners to master femoral venipuncture catheterization, and is welcomed by medical students.

摘要： 目的　探讨股静脉穿刺置管术临床带教方式在肿瘤科的运用，提高临床轮训初学者对股静脉穿刺置管技术的掌握程度。方法　选取2020年2月至2022年2月广州中医药大学第一附属医院肿瘤中心轮训实习医师一共28名，开展轮训实习医师股静脉穿刺置管术临床带教，统计实习医师对在带教过程中股静脉穿刺置管成功情况，分享总结股静脉穿刺置管的经验教训。统计学方法采用χ²检验、ANOVA（方差分析）。结果　研一、研二、研三带教穿刺次数分别为（3.62±0.92）次、（3.83±1.19）次、（4.25±1.49）次，差异无统计学意义（F=0.55，P=0.582）；研一、研二、研三成功置管时间分别为（5.75±2.77）min、（6.17±3.21）min、（3.88±1.64）min，差异无统计学意义（F=1.79，P=0.188）；研一、研二、研三出科时置管成功率别为50%（4/8）、75.0%（9/12）、62.5%（5/8），差异无统计学意义（χ²=1.32，P=0.516）；研一、研二、研三掌握穿刺点定位比例分别为87.5%（7/8）、91.7%（11/12）、100.0%（8/8），差异无统计学意义（χ²=0.99，P=0.61）。结论　股静脉穿刺置管术在肿瘤疾病患者运用广泛，因其有一定的难度及风险，对操作者的熟练程度要求更高。从研一、研二、研三3个不同年级医学生带教培训结果来看，该穿刺技术临床带教方式总体效果基本一致，有助于指导初学者掌握股静脉穿刺置管术，受到医学生欢迎。
