Main outcome measures
In 51 subjects with DNSI, 15 cases were not treated with abscess
incision and drainage; 36 cases were treated by incision, drainage and
dressing change: 23 cases were treated with traditional incision and
drainage and dressing change; 13 cases were given the combined treatment
of incision and drainage, pyogenic cavity aerobic therapy and negative
pressure drainage. The average number of days of dressing change and
average hospital stay were compared between the two groups
Results
The average hospitalization days in the traditional dressing group were
(26.74±3.393) days, and the average days of postoperative dressing
change were (25.91±3.427) days. The average hospitalization days in
pyogenic cavity aerobic therapy + negative pressure drainage were
(11.08±2.108) days, and the average days of postoperative dressing
change were (3.692±0.208) days. All 51 patients were cured.
