The chances of infection occurring with soot hemostasis are very high, and the effect of hemostasis is not exact and has long been eliminated clinically. The main reasons are as follows: First, soot is not absolutely sterile, and scattering soot on the bleeding wound may cause a significant increase in the number of bacteria in the wound, aggravating the infection of the wound and causing fluid and pus accumulation in the wound, which is not conducive to faster wound recovery. Second, the effect of soot hemostasis is not exact, for traumatic capillary bleeding, even without soot hemostasis, the patient’s coagulation function is normal, bleeding from the trauma can stop on its own. For trauma with arterial and venous active bleeding, at this time, sprinkling more soot on the trauma will not stop the active bleeding on its own, and the trauma must be thoroughly disinfected and cleared, ligated and sutured to achieve a better hemostatic effect. Therefore, the use of soot to stop bleeding is not recommended clinically.
