摘要
目的 探讨明胶纤维网在不同出血创面的止血效果。 方法 (1)临床观察 35 0例急诊创伤和手术出血病人 ,根据出血性质分为浅表创面出血、深部创面出血和实质脏器出血 3类。观察比较明胶纤维网 (GF)、氧化纤维素 (OC)和明胶海绵 (GS) 3种止血材料的止血时间 ,并与医用纱布进行对比。 (2 )扫描电镜观察 3种止血材料的结构。 结果 (1)浅表创面各组止血时间无显著性差异 (P >0 .0 5 ) ;在深部创面GF组 ,止血时间与GS和OC比较有显著性差异 (P <0 .0 5 )。但在内脏渗血创面 ,GF、OC和GS的有效率无显著性差异 (P >0 .0 5 )。 (2 )扫描电镜显示 ,GF呈网络状致密结构 ,OC和GS的结构均有较大网眼。 结论 明胶纤维网结构致密 ,因而在深部出血创面止血效果较结构疏松的氧化纤维素和明胶海绵为佳。
Objective To investigate the hemostatic effect of gelatin fleece (GF) on different traumatic bleeding. Methods In clinic, 350 patients who suffered bleeding from trauma and surgical operation were studied. There were three types of bleeding, i.e. bleeding of superficial trauma, of deep trauma and of parenchymatous organs according to bleeding character. Hemostatic time of GF, oxidized cellulose (OC) and gelatin sponge (GS) was recorded and compared with that of medical gauze. The structure of hemostatic agents was observed using scanning electron microscope (SEM). Results There was no significant difference in the time to stop bleeding of superficial trauma. But a significant difference in the time to stop bleeding of deep trauma appeared compared with that of GS and OC ( P <0.05). In the bleeding trauma of internal organs, the effect of GF, OC and GS was similar. SEM showed that the reticular structure of GF was much denser than that of GS and OC. Conclusions For its dense structure, GF had a better hemostatic effect on bleeding of deep trauma than that of OC or GS.
