目的 探讨外科标准“4C”(颜色、致密度、收缩性、出血 )在判定海水浸泡肢体火器伤失活肌组织的可靠性。方法 以滑膛枪发射质量为 0 .2 5 g、速度为 6 0 0～ 80 0 m/ s钢球击中兔后肢 ,将致伤兔浸泡于人工海水中 30～ 6 0 min后出水。伤后 6～ 8h以“4C”标准分级判定肌组织活力 ,并运用图象分析技术 ,观察损伤组织显微病理改变与“4C”标准之间的关系。结果 χ2 检验显示“4C”标准中与失活组织的密切程度依次为 :收缩性、出血、致密度 ,而颜色与肌组织活力无关。病理观察显示肌组织变性、坏死 ,尤以肌间隙肿胀明显。结论 判定海水浸泡火器伤失活组织主要依据肌组织的收缩性、出血与致密度的变化。
Objective To investigate the reliability of surgical criteria “4C” (color, density, contractility, hemorrhage) in determining the inactivation of muscle tissue in seawater immersion limb firearm injuries. Methods After the gunshot was hitched to the hindlimb of the rabbits at a mass of 0.25 g and a speed of 600 ~ 80 0 m / s, the injured rabbits were immersed in artificial seawater for 30-60 min and then the water was discharged. Six to eight hours after injury, muscle tissue activity was determined by “4C” standard grading, and the relationship between microscopic pathological changes and “4C” criteria was observed by image analysis technique. Results χ2 test showed that the “4C” standard with the inactivation of the organization in close order: systolic, hemorrhage, density, and color and muscle activity has nothing to do. Pathological examination showed that muscle tissue degeneration, necrosis, especially in the obvious swelling of the muscle space. Conclusion It is concluded that the deactivation of seawater immersion firearm wound mainly depends on the contractility of muscle tissue, the change of bleeding and density.
