| 摘 要： | 目的 探讨舱室爆炸致大鼠腹部损伤的伤情特点及规律.方法 120只SD大鼠随机分为舱内组、舱外组,每组60只.舱内组在模拟装甲舱室内用600mg DDNP瞬时电雷管爆炸;舱外爆炸条件与舱室相同,压力传感器测定冲击波物理参数.观察爆炸后大鼠存活情况及腹内脏器大体形态学改变,并进行损伤严重程度病理学评分.结果 死亡率:舱内组即刻21.7%,舱外组6.7%(χ2=5.551,P=0.018).腹腔脏器损伤发生率:舱内组76.7%,舱外组53.3%(χ2=7.179,P=0.007).舱内组肝、结肠损伤较多,而舱外组结肠、胃损伤率较高.肝损伤以包膜下血肿和裂伤常见,空腔脏器损伤以浆膜下出血常见.病理学评分:舱内组(2.63±1.25)分,舱外组(1.97±0.86)分(Z=-2.394,P=0.017).结论 舱室爆炸致腹部损伤程度较舱外开阔地更严重;舱室爆炸腹部受损器官以肝和结肠为主,开阔地爆炸腹部受损器官以结肠为主.

| Abstract: | Objective To identify injury characteristics associated with abdominal wound of rats caused by explosion in enclosed spaces.Methods A total of 120 male rats were randomly divided into 2 groups: enclosure and free-field group caused by explosion with 600mg DDNP instantaneous electric detonator.Physical parameters of blast wave were measured using pressure transducers.After explosion,bleeding in the abdominal cavity,the distribution and types of internal organs were detected.The pathological score of abdomina... |
