Negative pressure wound therapy promotes healing and reduced pain in patients with acute suppurative mastitis

Abstract

BackgroundThe purpose of this study was to compare the outcomes of vacuum sealing drainage (VSD) and conventional incision and drainage (I&D) for treating acute suppurative mastitis.MethodsHospital medical records were searched for patients 20–50 years of age who were diagnosed with acute suppurative mastitis from January 2014 to December 2018, and treated with traditional I&D or VSD. Patients were divided into those treated with VSD and I&D, and outcomes including pain, healing time, length of hospital stay, and length of antibiotic course were compared between the groups. Pain was evaluated with a numeric rating scale from 0 (no pain) to 10 (most severe pain). Subgroup analysis of lactating women was also performed.ResultsThere were 110 women who received traditional I&D, and 105 women that received VSD included. The 2 groups were similar with respect to age (31.1 ± 4.8 vs. 29.9 ± 4.4, p = 0.058), and disease characteristics. The median pain score of women who received VSD (5 [IQR 5–6]) was significantly less than that of women who received I&D (8 [IQR 7–8]) (p < 0.001). The time for healing was significantly less in women who received VSD (40 days [IQR 30–45 days]) compared to I&D (60 days [IQR 45–70 days]) (p < 0.001). The length of hospital say and the length of antibiotic treatment were similar between the 2 groups. Results were similar for lactating women.ConclusionsVSD is effective for treating acute suppurative mastitis with reduced pain and shortening healing time.
