Topical Hemostatic-Anesthetic Solution to Reduce Bleeding During Mohs Micrographic Surgery: A Case Control Study

Background: Between stages of Mohs micrographic surgery, the wound is dressed and the patient waits for the histopathological results. Objective: To investigate the efficacy of a hemostatic-anesthetic solution-impregnated gauze in decreasing bleeding between Mohs stages. Materials and Methods: Twenty patients were treated with a hemostatic-anesthetic solution composed of tranexamic acid, adrenaline, and lidocaine (TAL), and 20 others were treated with a saline solution for control. At the second Mohs stage, size measurements of the blood stain on a Telfa pad and the defect were recorded. The Rotation Thromboelastometry Method (ROTEM) was used to investigate a possible effect of lidocaine and adrenaline on the clot stability induced by tranexamic acid. Results: The ratio of blood stain size to Mohs defect size in the hemostatic anesthetic solution group was 1:1.47, whereas the ratio in the control saline group was 1:3.37 (P<.001). Results of the ROTEM test showed that lidocaine and adrenaline did not interfere with the effect of tranexamic acid on clot formation and stability. Conclusion: The application of gauze impregnated with tranexamic acid, adrenaline, and lidocaine on a surgical wound may be effective in reducing bleeding between Mohs stages.
