Frostbite can lead to severe consequences including loss of digits and limbs. One of the mechanisms of frostbite includes vascular thrombosis. The use of tissue plasminogen activator (tPA) in frostbite has been shown to be effective in case reports and small prospective studies. ⋯ After rapid rewarming, the use of tPA is safe and effective at reducing the number of digits amputated. Patients who had less of a response to tPA were those who had an unknown duration of cold exposure along with drug or alcohol intoxication at presentation. Utilizing a guideline with clear criteria will help facilitate determining appropriate patients to safely treat with tPA for frostbite injury.

Silver-based dressings are commonly used in burn care. Silver sulfadiazine use is associated with elevated blood, urine, and tissue levels of silver ion. We examined wound and tissue levels of silver ion in a two-species model of sulfur mustard chemical burn injury treated with two different silver-based dressings. ⋯ Wound levels were higher in minipigs than in hairless guinea pigs and were higher in animals treated with silver-nylon burn wound dressings than with silver-calcium alginate dressings. Silver ion could be detected in some wounds 40 days after dressings were removed. In a chemical burn model, application of silver-nylon or silver-calcium alginate dressings is associated with elevated wound levels but negligible tissue levels of silver ion.

Review
Patient Experience of Wearing Compression Garments Post Burn Injury: A Review of the Literature.
This review was conducted to critically appraise the literature regarding the patient's lived experience of, and adherence to, wearing compression garments post burn injury. Scholarly articles were identified from searches of the following databases: Pubmed, Cochrane Central, CINAHL, PsycINFO, and OT Seeker. Combinations of key words including compression therapy/garment, pressure therapy/garment, burn(s), adherence, and patient experience were utilized. ⋯ Minimal investigation has been completed regarding the impact of these patient's lived experiences on the adherence to wearing compression garments. Additional research using qualitative methods is required to gain a deep understanding of patient's experiences and perspectives of wearing compression garments and how these experiences influence on their adherence to wearing them. Identification of key experiences that lead to patients removing their compression garments may lead to modification of treatment and system approaches to better align with patients' needs and development of potential interventions that promote adherence.

Randomized Controlled Trial
Oxandrolone Coadministration Does Not Alter Plasma Propranolol Concentrations in Severely Burned Pediatric Patients.
The systemic impact of severe burn injury results in a variety of disorders that require therapeutic intervention. Propranolol, a nonselective β1, β2-adrenergic receptor antagonist, reduces resting heart rate and cardiac work caused by elevated circulating catecholamines. Oxandrolone, a testosterone mimetic, promotes protein synthesis and anabolism to counter muscle wasting. ⋯ The addition of oxandrolone did not affect any of the measured parameters. Oxandrolone coadministration does not alter propranolol's plasma concentration, half-life, or effect on heart rate. This study is registered at clincialtrials.gov: NCT00675714.

Comparative Study Controlled Clinical Trial
Enzymatic Versus Traditional Surgical Debridement of Severely Burned Hands: A Comparison of Selectivity, Efficacy, Healing Time, and Three-Month Scar Quality.
Severe burns of the hands are extremely challenging, given their anatomic complexity and vulnerability. Although excisional debridement with autografting remains the standard of care (SOC), previous studies have shown that use of enzymatic debridement with bromelain (NexoBrid, EDNX) enables rapid, selective enzymatic debridement, preserving viable tissue. To date, only two studies accruing data on EDNX in this setting have been published. ⋯ The number of wounds requiring autografting was certainly reduced (15% vs 95%; P = .034), as was time to complete healing after first debridement (23.30 vs 32.00 days; P < .001), and early scar quality after 3 months was nearly equivalent, with only heightened local redness in the EDNX group (P < .001). Compared with TSD, EDNX was superior in burn depth evaluation, tissue preservation, completeness of debridement, and wound closure. Scar quality after 3 months did not differ substantially.
