Abstract: To study the hemostasis effect of disposable packing hemostasis on bleeding due to trauma of medium-sized artery,and compare the hemostasis effect with that of styptic powder.9 miniature pigs were divided into packing hemostasis group,styptic powder group and blank group.Establishing bleeding of forelimb medium-sized artery models on miniature pigs,haemostasis treatments were performed on individual group and parameters were measured, such as hemostatic time,regional maximum temperature and blood pressure.In addition,the tissues surrounding the haemostatic spot were picked for observation. When comparing the haemostatic effect,we found that the disposable packing hemostasis and styptic could stop bleeding quickly,and the effect of these two methods on hemostatic time has no difference;the temperature raised by styptic powder were higher than that of packing hemostasis,in addition, they all cause light tissue damage for raw surface and surrounding tissues. Disposable packing hemostasis could effectively stop bleeding caused by forelimb medium-sized artery,it could act as a secure and effective dressing for treating acute hemorrhage.
