Nexobrid Use in the Elderly

Abstract

Background: Enzymatic debridement with Nexobrid (NXB) is established for burn care, but specific outcomes in the elderly remain poorly characterized. This study evaluates the safety, efficacy, and clinical outcomes of NXB in patients aged ≥65 years.

Methods: A retrospective case-series of 43 consecutive elderly patients (mean age 74.5 years) with deep partial- to full-thickness burns treated with NXB at a single burn center. Data on demographics, burn characteristics, treatment chronology, and complications were analyzed.

Results: The median total burn surface area (TBSA) was 11%. NXB was applied selectively, with a mean debrided area of 7.41% TBSA, primarily on limbs and hands. While 76.7% of patients ultimately required surgical autografting, no patient required an escharotomy in NXB-treated areas. The mortality rate was 25.6%, which was lower than expected for a median revised Baux score of 90, which is expected to be more than 50%. Hypertrophic scarring occurred in 28.1% of survivors, associated with a prolonged median healing time of 63 days.

Conclusions: In elderly burn patients, NXB facilitates precise eschar removal and reliably prevents compartment syndrome, demonstrating a strong safety profile even in high-risk individuals. Its primary benefit shifts from reducing surgical incidence to optimizing the wound bed for grafting. These findings support the use of NXB in the elderly, with the understanding that subsequent grafting is often still required due to age-related delayed healing.
