If the patient’s own coagulation function is normal and the cut is superficial, with only a small amount of local capillary bleeding, a vital iodine cotton ball can be used, and after local disinfection, the sterile cotton ball can be compressed for about 3-5 minutes, and most patients can stop bleeding on their own. If necessary, Yunnan Baiyao can be used orally to enhance the hemostatic effect. 2, if the patient’s own coagulation function is poor and deeper cut by the knife, accompanied by active bleeding of the local arterial vessels. The hemostatic effect of oral medication or local compression is not good enough, so it is recommended that patients go to the hospital in a timely manner. Thorough debridement, disinfection, suturing and hemostatic treatment of the trauma can be given to better control local bleeding. Postoperatively, local dressing changes need to be strengthened to avoid infection of the incision.
