Hypertrophic Granulation Wounds Treated With Silver Nitrate Sticks or With Topical Steroid: Rate of Wound Closure

Hypertrophic granulation (HG) is abnormal granulation tissue raised above the level of surrounding intact skin and is thought to delay wound healing. Effective treatment to eliminate HG could speed healing, but this is not well studied. Two common treatments are chemical cautery with silver nitrate, and the use of topical steroids. In a Midwestern burn and wound clinic, both of these treatments are employed. A quality improvement project compared wound size reduction for HG wounds undergoing the two treatment modalities. Retrospective chart review identified HG wounds treated during a 1-year period, and compared wound size prior to and after 1 month of treatment (length, width, and surface area). Results were presented to the clinic staff, and 1 year later the quality assurance project was repeated. The initial audit found data on 18 patients treated with silver nitrate cautery, and 16 patients treated with 1% hydrocortisone cream. Median length and width were decreased by 5 mm with silver nitrate cautery treatment, and by 14 mm with 1% hydrocortisone treatment (P < .05). The repeat audit 1 year later found 10 patients treated with silver nitrate, and 38 treated with hydrocortisone. Median length and width decreased by 0 and 2 mm respectively for silver nitrate cautery treatment, and 15 and 10 mm for 1% hydrocortisone treatment (P < .05). In conclusion, this uncontrolled review suggests faster healing in HG wounds treated with 1% hydrocortisone compared with those treated with silver nitrate cautery. Confirmation with controlled and randomized studies is warranted.
