Therapeutic effect of vacuum sealing drainage on chronic traumatic subcutaneous hematoma

【Abstract】 Objective To study the clinical effect of vacuum sealing drainage in the treatment of chronic traumatic subcutaneous hematoma. Methods Patients of chronic traumatic subcutaneous hematoma who were admitted to the Department of Burns and Plastic Surgery of Jiaozhou Central Hospital of Qingdao from June 2018 to June 2021 were included and randomly divided into the control group and the experimental group according to the random number table method. The subcutaneous hematoma was incised for debridement, and the blood clots, exudates, necrotic tissues, and pseudosynovium in the cavity were removed. The control group was treated with vaseline oil gauze filling drainage and dressing change method, and the experimental group was treated with vacuum sealing drainage and dressing change method. During the treatment, the closing time of subcutaneous hematoma cavity was observed and compared between the two groups. Results A total of 42 patients with chronic traumatic subcutaneous hematoma were enrolled, 21 in the control group and 21 in the experimental group, including 11 males and 10 females in the control group, aged (46. 2±12. 4) years; 13 males and 8 females in the experimental group, aged (44. 3±10. 6) years. After treatment, all the subcutaneous hematoma spaces were closed in the 42 patients. The closing time of subcutaneous hematoma cavity in the experimental group was (15. 52 ± 1. 69) days, which was significantly shorter than that in the control group (24. 14±2. 57) days. There was a significant difference between the two groups (P < 0. 01). Conclusions After incision and debridement of chronic traumatic subcutaneous hematoma, vacuum sealing drainage and dressing change can actively and fully drain the exudate in the cavity, residual blood clots, necrotic tissues, and pseudosynovium, promote the growth of new granulation tissue, which is more conducive to the closure of the cavity of subcutaneous hematoma, and shorten the clinical treatment cycle.
