摘要目的 探讨动物皮肤和人工皮肤在临床技能模拟训练中的应用效果.方法 选择2018年在北京医院进行第一年住院医师规范化培训的48名学生为研究对象,按照随机数字表法将其平均分为动物皮肤组和人工皮肤组,每组24人,分别完成规则伤口缝合(站1)、不规则伤口缝合(站2)、深部伤口缝合(站3)的学习和测评.使用客观结构化技能评估(objective structured assessment of technical skills,OSATS)对学生的技能和总体表现进行测评.分别调查10个动物皮肤和10个人工皮肤的使用寿命.结果 动物皮肤组站1成绩为(14.8±2.1)分,人工皮肤组站1成绩为(14.6±1.8)分,两组差异无统计学意义(P=0.666);动物皮肤组站2成绩为(13.9±1.9)分,人工皮肤组站2成绩为(12.1±2.1)分,两组差异具有统计学意义(P<0.01);动物皮肤组站3成绩为(12.8±2.0)分,人工皮肤组站3成绩为(11.4±2.1)分,两组差异具有统计学意义(P=0.03).动物皮肤的使用寿命为(4.5±1.2)小时,人工皮肤的使用寿命为(13.5±2.6)小时,两者差异具有统计学意义(P<0.01).结论 动物皮肤和人工皮肤在规则伤口缝合训练中的效果无明显差异,在不规则伤口和深部伤口的缝合训练中,动物皮肤优于人工皮肤,人工皮肤使用寿命更长.

abstractsObjective To evaluate the effect of animal skin and artificial skin in clinical suture skills training. Methods Forty-eight medical students who received standardized training were enrolled in this study. The students were asked to perform 3 suturing tasks on the animal skins or artificial skins:neat wound suture ( station 1);irregular wound suture ( station 2);deep tissue suture ( station 3) . The skill and general performance were assessed by the objective structured assessment of technical skills ( OSATS ) scoring tool. The service lives of 10 animal skins and 10 artificial skins were investigated. Results In station 1,the scores were 14. 8±2. 1 in animal skins group and 14. 6±1. 8 in artificial skins group,there was no statistical difference between the two groups (P=0. 666). In station 2,the scores were 13. 9±1. 9 in animal skins group and 12. 1± 2. 1 in artificial skins group, and the score of animal skins group was significantly better than that of artificial skins group (P<0. 01). In station 3, the scores were 12. 8±2. 0 in animal skins group and 11. 4±2. 1 in artificial skins group, and the score of animal skins group was better than that of artificial skins group (P=0. 03). The service life of animal skin was (4. 5±1. 2)hours, and that of artificial skin was (13. 5±2. 6) hours. The difference was significant (P<0. 01). Conclusions In neat wound,the suture skills training in animal skins and artificial skins have the same effect. In suture training of irregular wound and deep tissue,&nbsp;the animal skins are better than artificial skins.
