Enzymatic Debridement (Nexobrid) on Burned Hands: Retrospective Review from a Burn Referral Center in Spain.

Background:In deep burns, the gold standard of treatment is surgical debridement and coverage, but in hands, this may lead to poor aesthetic and functional results due to the complexity of this anatomical area. Enzymatic debridement (Nexobrid) allows for the preservation of the dermal remnant and reduces the number of skin grafts when compared with surgical excision. The study aimed to analyze the patients with intermediate second-degree or deeper burns in hands who required surgical treatment after Nexobrid and those who avoided it. Methods:A descriptive retrospective study of all patients who underwent Nexobrid following hand burns between May 2015 and April 2020 treated in Vall d'Hebrón University Hospital was conducted. After the enzymatic debridement, the burn unit team determined if the burn required conservative treatment or surgery, based on the characteristics of the wound bed. Results:A total of 202 hands were collected. Most hands included in this study had deep second-degree burns (122; 60.4%). Almost half of the hands underwent surgery (99; 49%), and most had deep second-degree burns (61; 61.62%). During follow-up, 24 hands required surgery for sequelae (11.88%) and 62 did not undergo follow-up (30.69%). In the group that needed sequelae surgery, 21 needed surgery after Nexobrid and three of them were healed with conservative treatment after Nexobrid (P < 0.001). Conclusions:Nexobrid decreases the number of surgical procedures in deep burns of the hand because more conservative attitudes are adopted. Also, it seems to reduce the need of surgery due to burn sequelae.
