实验用犬14只,用质量1.03g,平均射速1434m/s的钢珠弹致伤颌面部。分别于伤后6h、24h清创,清创时肌肉组织的切除范围为0.5cm,创口初期缝合,一周内肌注抗生素预防感染。观察创口愈合及创缘肉芽组织细菌污染情况。结果显示:①在本实验致伤条件下,清创范围为0.5cm,清创后初期缝合,其伤口一期愈合率为94.4％;②在伤后6h和24h清创,伤口愈合情况和伤道肌肉组织羟脯氨酸含量无显著差异,但伤后6h清创可减少局部组织的细菌污染程度;③清创后应用足量有效抗生素是预防伤口感染,保障伤口愈合的重要措施。
Experimental dog 14, with a mass of 1.03g, the average velocity of 1434m / s steel ball injury maxillofacial. Respectively after 6h, 24h debridement, debridement muscle tissue resection range of 0.5cm, the initial wound suture, intramuscular injection of antibiotics within a week to prevent infection. Observation of wound healing and wound edge granulation tissue bacterial contamination. The results showed that: ①In the experimental wound conditions, the range of debridement was 0.5cm, and the primary wound healing rate was 94.4% after initial debridement; ② The debridement wounds at 6h and 24h after injury, wound healing and wound healing There was no significant difference in the content of hydroxyproline in muscle tissue, but debridement at 6h after injury could reduce the degree of bacterial contamination in the local tissues. (3) The application of sufficient effective antibiotics after debridement is an important measure to prevent wound infection and ensure wound healing.
