通过四肢爆炸伤动物模型研究局部软组织损伤特点

To study the local parenchyma injury characteristic by limbs of animal

目的:通过四肢可控性爆炸伤动物模型,探讨四肢爆炸伤的的局部损伤特点,为四肢爆炸伤的治疗提供实验依据。方法:采用由定向控制管、肢体控制架、能量控制装置三部分构成的实验装置,炸伤四肢,通过炸伤后动物大体标本、局部组织病理变化等,探讨四肢爆炸伤的特点。结果:通过调整能量控制装置与肢体的距离,获得了不同的肢体损伤模型;局部软组织损伤严重,在创周0～3cm的距离内,局部软组织损伤逐渐减缓。结论:通过调节爆炸源的距离,可得到不同的爆炸伤动物模型,创周皮肤2cm内和肌组织1cm内软组织损伤严重,需要彻底清创。
