Objective To evaluate the value of goat models in training and promoting key first aid skills of combat medics.Methods A total of 45 goats were anaesthetized with ketamine.Asphyxia models were created by wadding the goats' mouths and noses,pneumothorax models were established by piercing goats' chests,and massive hemorrhage models were built by piercing goats' limbs.Based on the above models,83 combat medics were trained to perform tracheotomy,tube thoracostomy,and artery suture.The differences in mastering these three skills before training,after training (immediately after training),and one year after training were recorded and compared.The effect of military service length and education background on the skill examination was evaluated before and after training.The recognition of the goat models from the combat medics was investigated.Results Before the training,success rates of performing tracheotomy,tube thoracostomy and artery suture were 39％,33％ and 25％,respectively.After the training,the corresponding parameters were 94％,86％ and 64％,respectively.One year after training,the success rates dropped to 66％,62％ and 43％,respectively.Compared with the status before training,the improvement of three skills was statistically significant after training (P ＜ 0.01).The decrease of three skills one year after training was statistically significant (P ＜ 0.01).The military service length had effects on the performance before training (P ＜ 0.05).And the military service length had no effect on the performance after the training (P ＞ 0.05).Education background had effects on the performance of surgical success rates before (P ＜ 0.01) and after training (P ＜ 0.05).According to the cross-sectional study,80％ of the military doctors chose the goat models as the first option for training.Conclusion Goat models are not only easy to be created but also are suitable for training the combat medics in key first aid skills.Such model is worthy of further application.
