Acquisition of Basic Surgical Skills (BSS) are essential for medical students. The objective was to determine it's fidelity impact.
Using four suturing models (SM) (pigskin, sponge, commercial pad, and orange), SM-quality and student-SM interaction were evaluated. After a 1-h class, participants were divided into groups and randomly assigned exercises in SM in 15-min intervals. The experiment included completing three individual simple stitches and a 3-stitch continuous suture in each SM.
Eighty-two medical students participated. Suturing quality was better in pigskin and sponge, which were also the preferred models (p < 0.001). Significant differences in quality between the insertion and exit point, and firmness of knots (p < 0.05) in both simple and continuous sutures, as well as between length and distance in continuous ones (p < 0.001) were identified.
Acquisition and quality of BSS are influenced by the intrinsic characteristics of SM. An adequate degree of resistance, consistency, and elasticity are necessary.
掌握基本外科手术技能（BSS）对医学生至关重要。目的是确定其逼真度的影响。
使用四种缝合模型（SM）（猪皮、海绵、商用垫和橙子），对SM质量和学生与SM的互动进行评估。经过1小时的课程后，参与者被分成小组，并以15分钟的间隔随机分配在SM中进行练习。实验包括在每个SM中完成三个单独的简单缝合和一个三针连续缝合。
82名医学生参与。猪皮和海绵的缝合质量更好，这也是首选模型（p < 0.001）。在简单缝合和连续缝合中，进出针点的质量、结的牢固程度（p < 0.05）以及连续缝合中长度和间距之间（p < 0.001）均存在显著差异。
BSS的掌握程度和质量受SM内在特性的影响。需要有足够的阻力、一致性和弹性。
