Burn injury results in hypercoagulability and an increased venous thromboembolism risk. However, the most effective chemoprophylaxis for burn-injured patients has yet to be elucidated. Therefore, this study aims to identify the safety and efficacy of a burn center's venous thromboembolism protocol modification which increased the dose of enoxaparin from 40mg daily to 40mg twice daily with peak anti-Xa level adjustments.

Article Synopsis
  • Dynamically titrated crystalloids are the primary method for treating burn shock, and this study investigates whether adding allogeneic plasma (known as plasma-inclusive resuscitation, or PIR) affects coagulation negatively.
  • The study involved 35 patients treated with PIR, analyzing their blood to check for coagulopathy at multiple points during treatment, finding no significant coagulation issues or complications like transfusion reactions.
  • Results indicate that PIR does not cause harmful blood clotting changes compared to baseline in burn patients, suggesting it may be safe, but further research is necessary to confirm these results and assess its effectiveness in burn resuscitation.

  • The study investigates the effectiveness of combining autologous skin cell suspension (ASCS) with meshed split-thickness skin grafts (mSTSG) for treating large burns, aiming to improve healing times and reduce aesthetic issues.
  • Experiments conducted on pigs showed that wounds treated with ASCS had significantly faster re-epithelialization rates compared to those without ASCS, particularly noted on days 3, 5, and 7 post-grafting.
  • However, despite the improved healing rates, the presence of ASCS did not affect the patterning of the scars, indicating that while ASCS enhances healing, it may not address visual scarring issues.

Objectives: Fractional ablative CO laser (FLSR) is used to treat hypertrophic scars (HTSs) resulting from burn injuries, which are characterized by factors, such as erythema, contracture, thickness, and symptoms of pain and itch. Traditionally, waiting a year after injury for scar maturation before starting laser treatment has been recommended; however, the potential benefits of earlier intervention have gained popularity. Still, the optimal timing for beginning laser intervention in patients with HTSs remains uncertain.

  • - The study aimed to explore how different pulse energy settings of fractional ablative CO lasers affect gene transcription related to wound healing in uninjured pig skin.
  • - Researchers treated skin samples with laser settings of 70, 100, and 120 mJ and analyzed gene expression over time, focusing on eight specific genes tied to healing and the extracellular matrix.
  • - Results showed that while laser treatment enhanced the expression of six out of eight genes, varying pulse energies did not lead to significant differences in gene transcription levels, suggesting that lower energy may suffice for effective treatment.

Objectives: Dyschromia is an understudied aspect of hypertrophic scar (HTS). The use of topical tacrolimus has successfully shown repigmentation in vitiligo patients through promotion of melanogenesis and melanocyte proliferation. It was hypothesized that HTSs treated with topical tacrolimus would have increased repigmentation compared to controls.

Resuscitation is required for the management of patients with severe thermal injury. Some of the initial pathophysiologic events following burn injury include an exaggerated inflammatory state, injury to the endothelium, and increased capillary permeability, which all culminate in shock. Understanding these processes is critical to the effective management of patients with burn injuries.

Article Synopsis
  • Laser treatments, specifically CO fractional ablative laser scar revision, have been studied for their effectiveness in reducing hyperpigmentation in scars across different skin types using both qualitative (POSAS and VSS) and quantitative (melanin index) measures.
  • A cohort of 63 patients, all of whom had multiple laser sessions, was analyzed to assess changes in pigmentation and other demographic variables like age, gender, and ethnicity.
  • Preliminary results indicate most patients experienced a decrease in hyperpigmentation, but detailed outcomes and statistics will need further investigation to fully understand treatment effectiveness.

The Department of Defense (DoD) is increasingly dependent on highly technological weapon systems, but the human is still at the heart of our war-fighting efforts. In order to maintain an effective fighting force, we must optimize and sustain human performance, which is defined as the successful completion of a specified task within an available performance capacity that meets or exceeds the mission demands. When health and performance are optimized and sustained, the costs of warfighter care and disability compensation are reduced and the quality of life is enhanced.

Burn scars, and in particular, hypertrophic scars, are a challenging yet common outcome for survivors of burn injuries. In 2021, the American Burn Association brought together experts in burn care and research to discuss critical topics related to burns, including burn scars, at its State of the Science conference. Clinicians and researchers with burn scar expertise, as well as burn patients, industry representatives, and other interested stakeholders met to discuss issues related to burn scars and discuss priorities for future burn scar research.

Wound infections and sepsis are significant causes of morbidity after burn injury and can be alleviated by early excision and grafting. In situations that preclude early surgery, topical agents allow for a safer delay. Cerium nitrate compounded with silver sulfadiazine (Ce-SSD) is a burn cream that provides broad antibacterial activity, forms a temporary barrier, and promotes re-epithelialization.

  • Negative pressure wound therapy (NPWT) can help improve the adherence of meshed split thickness skin grafts (mSTSGs) when used alongside autologous skin cell suspension (ASCS) after burn injuries.
  • A study using Duroc pigs showed that both NPWT and traditional dressings led to successful healing with no significant differences in re-epithelialization, pigmentation, or blood vessel density between the two methods.
  • However, NPWT demonstrated advantages in terms of reduced graft loss and improved elasticity, suggesting that NPWT can safely be used with ASCS and mSTSGs in treating full-thickness burns.

The success of autologous split-thickness skin grafts (STSGs) in the treatment of full-thickness burns is often dependent on the dressing used to secure it. Tie-over bolsters have been used traditionally; however, they can be uncomfortable for patients and preclude grafting large areas in one definitive operation. Negative pressure wound therapy (NPWT) is used as an alternative to bolster dressings and may afford additional wound healing benefits.
