BackgroundThere is scarce literature regarding the use of continuous peripheral nerve blocks in acute burn patients, who may be at higher risk for catheter-related complications, including infection. We sought to describe our center's experience and infection rate with continuous perineural catheters in the setting of pain management for patients suffering from burns.MethodsA retrospective observational study was performed including all patients admitted to an American Burn Association-verified regional burn center between January 2018 and July 2023 who received a continuous peripheral nerve block for an acute burn injury.ResultsThere were 281 patients in the study cohort who received 484 perineural catheters. The cohort was 52% men with a median age of 39 years (IQR 30-55). A catheter-associated infection, defined as a clinical diagnosis by the treating physicians requiring the need for treatment with antibiotics or surgical debridement, was identified in six perineural catheters (1.2%, 95% CI 0% to 2.2%) involving six different patients (2.1%, 95% CI 0% to 3.8%). The median total body surface area burned was 5% (IQR 2-9%) and 20% of patients had full-thickness burns. The most commonly used catheters were infraclavicular (49%), popliteal sciatic (29%), femoral (19%), and adductor canal (17%). One-third (33%) of patients did not require operating room debridement as the block provided sufficient analgesia for bedside debridement. The median duration of catheter use was 6 days (IQR 4-8). There were no documented cases of nerve injury or toxicity, vascular injury, or local anesthetic systemic toxicity.ConclusionsIn our practice, continuous perineural catheters in the setting of acute burns are associated with an infection rate comparable to other surgical populations.© American Society of Regional Anesthesia & Pain Medicine 2024.
