Risk stratification is of utmost importance in burn therapy. However, suitable bedside biomarkers to evaluate the emerging inflammatory response following burn injuries are missing. Serum cholinesterase (butyrylcholinesterase, BChE) has been shown to be a clinically relevant biomarker in acute inflammatory diseases including burns. In this observational cohort study BChE activity was measured by using point-of-care testing (POCT), a novel method in acute burn care. POCT measurements were performed at emergency room admission (ERA) of 35 patients and repeated 12, 24 and 48 h later. All patients or their legal designees gave informed consent. Patients with burn injuries showed sustained BChE activity reduction following hospital admission. BChE activity correlated negatively with burn injury severity, organ failure severity and intensive care unit resource requirements. BChE activity measured at ERA and 12 h later identified survivors and predicted 28-day patient outcome with noninferior efficacy compared to the abbreviated burn severity index (ABSI) scoring. Finally, POCT-measured BChE activity might complement ABSI scoring and possibly improve early risk stratification in acute burn care therapy., (Copyright © 2020 Elsevier Ltd and ISBI.

Introduction: More than half a million patients suffer from minor burns in Germany per year. In 2018, almost 2000 patients needed intensive care for their burn injuries. Despite high standards of burn care, mortality remains high. Burn injuries may lead to long-term sequelae. In order to provide up-to-date burn care, guidelines are available online with public access., Methods and Results: This overview presents a summary of the German AWMF guideline for the treatment of thermal injuries in adults (https://www.awmf.org/leitlinien/detail/ll/044-001.html). Experts of eleven different medical organisations and specialties have contributed to this S2k guideline with their expertise. The focus of the article is on acute burn wound assessment, the indication for specialised care in burn centres, the management of the burn wound at the trauma scene and in hospitals as well as scar management and rehabilitation., Conclusion: This overview reports on the consensus-based treatment of acute burn wounds in adults in Germany. The article is intended to guide doctors and professional caretakers to perform state-of-the-art burn care. The current guideline aims to improve burn outcome., Competing Interests: HOR war beratend tätig für die Firma Birken und hat eine bezahlte Autorentätigkeit für uptodate.

Burn disasters present a challenge not only to burn centers but the entire healthcare system. Most burn centers worldwide are unprepared to deal with a burn disaster as it is an uncommon event. We investigated the status of burn center preparedness in German-speaking countries to respond to a burn disaster. Self-administered survey questionnaires were sent to the directors of burn centers; the questions of survey used before in a similar way in Belgium were translated into German language. Of the 46 questioned burn centers, 32 (78%) responded, including all of the German adult burn centers. A clear difference in the preparation status of the burn centers in the three countries was observed due to geopolitical factors such as decentralized healthcare systems. However, the healthcare system is generally well-prepared concerning command, transfer, and capacity to provide sustained supplies to handle a massive influx of patients. Nevertheless, there are some gaps in the areas of planning and preparation, funding for disaster activities, and regular training of staff for burn disasters. We call for a unified burn disaster plan and increased cooperation between burn centers and civil defense regarding communication and training. We strongly recommend the implementation of a special disaster fund and telemedicine in disaster management to circumvent shortages in burn staff., (Copyright © 2020 Elsevier Ltd and ISBI.

In sepsis and burns, ascorbic acid (AA) is hypothesized advantageous during volume resuscitation. There is uncertainty regarding its safety and dosing. This study evaluated high dose AA (HDAA: 66 mg/kg/h for 24 hours) versus low dose AA (LDAA: 3.5 g/days) administration during the first 24 hours in severely burned adults. We conducted a retrospective study comparing fluid administration before and after switching from low dose to HDAA in severely burned adults. A total of 38 adults with burns >20% TBSA, who received either HDAA or LDAA were included in this retrospective study. AA serum concentrations were quantified at 0, 24, and 72 hours postburn. HDAA impact on hemodynamics, acid-base homeostasis, acute kidney injury, vasopressor use, resuscitation fluid requirement, urinary output, and the incidence of adverse effects was evaluated; secondary clinical outcomes were analyzed. AA plasma levels were 10-fold elevated in the LDAA and 150-fold elevated in the HDAA group at 24 hours and decreased in both groups afterwards. HDAA was not associated with a significantly increased risk of any complications. A significant reduction in colloid fluid requirements was noted (LDAA: 947 ± 1722 ml/24 hours vs HDAA: 278 ± 667 ml/24 hours, P = 0.029). Other hemodynamic and resuscitation measures, as well as secondary clinical outcomes were comparable between groups. HDAA was associated with higher AA levels and lower volumes of colloids in adults with severe burns. The rate of adverse events was not significantly higher in patients treated with HDAA. Future studies should consider prolonged administration of AA., (© The Author(s) 2020. Published by Oxford University Press on behalf of the American Burn Association. All rights reserved.

Introduction: Burn trauma-related hypothermia is a frequent observation but risk factors and impact on patient related outcome are ambiguously reported. It is expected that hypothermia is associated with increased mortality and reduced overall outcome in severely burned patients, but available evidence is limited., Methods: This retrospective single-center-study reviewed preclinical service protocols and medical records of patients sustaining a burn with a total body surface area (TBSA) ≥15% from 2008 to 2012. General patient and burn specific characteristics, outcome parameters as well as body temperature at admission measured via urine catheter or nasal temperature probe were recorded and statistically analyzed comparing normothermic (≥36 °C), mild hypothermic (<36 °C) and severely hypothermic (<34.5 °C) patients. Chi-square test was performed to demonstrate impact of hypothermia on primary outcome parameters and to reveal risk factors for developing hypothermia. To assess independent influences on mortality, a multivariate logistic regression analysis was performed., Results: Out of 300 patients matching inclusion criteria, a sufficient record of temperature was found in 144 patients (48%). Out of 141 eligible patients with an average burn extent (SD) of 33.38% (24.5%) TBSA, 31.9% (n = 45) suffered from severe hypothermia (<34.5 °C) and 28.4% (n = 40) showed mild hypothermia. Total burn extent, presence of full thickness burns, presence of inhalation injury, preclinical mechanical ventilation and administration of sedative drugs were risk factors for developing hypothermia. Patients' age, total burn extent and presence of full thickness burns could be identified as independent factor for mortality. Although a trend towards an independent positive influence of normothermia at admission on mortality was seen, it was not statistically significant., Conclusion: Incidental hypothermia of burned patients is associated with an increased mortality and needs to be addressed by emergency health care providers and immediately at the burn center. Especially patients with extensive burns, full-thickness burns, inhalation injury or patients undergoing preclinical intubation are at risk for hypothermia and benefit from any measures for temperature preserving., (Copyright © 2019 Elsevier Ltd and ISBI.

Background: Burn-induced compartment syndrome is a severe sequela after circumferential burns of the extremities and is avoidable by immediate release of the underlying pressure under the eschar. Although the current gold standard is operative escharotomy, this procedure carries considerable morbidity. Our study evaluates the safety and effectiveness of immediate enzymatic debridement to prevent the need for operative escharotomy because of burn-induced compartment syndrome in selected patients., Patients and Methods: From 2015 to 2017, all patients suffering from deep circumferential burns of the upper extremities requiring operative escharotomy were potential candidates for the treatment algorithm evaluated by this study. Exclusion criteria involved burn trauma > 12 hours, clinically established burn-induced compartment syndrome, intolerance to the enzymatic debriding agent, dry burns requiring presoaking, as well as blast and electrical injuries requiring fasciotomy or carpal tunnel release. All patients with the inclusion criteria received enzymatic debridement with Nexobrid immediately after admission to our burn center. Enzymatic debridement was applied according to the manufacturer's recommendations. After enzymatic debridement, extremities were revisited every 2 hours for 24 hours to determine the need for conversion to conventional operative escharotomy. The indication for and time to skin grafting was reviewed, and functional outcomes assessed during follow-up examination., Results: Included in this sturdy were 13 patients with 20 burned upper extremities. Enzymatic debridement provided a sufficient eschar removal in all patients. Conversion to conventional operative escharotomy was thus not necessary in any patient. Secondary skin grafting was required in 9 patients. Functional outcomes were favorable 11.9 months after burn trauma., Conclusion: If the specific contraindications are respected, enzymatic debridement is safe and effective for the prevention of burn-induced compartment syndrome after deep circumferential burns at the upper extremity, and thus making operative escharotomy unnecessary., (Copyright © 2018 Elsevier Inc.

Introduction: Initial therapy of severe burns in specialized burn trauma centers is a challenging task faced by the treating multi-professional and interdisciplinary team. A lack of consistent operating procedures and varying structural conditions was recently demonstrated in preliminary data of our group. These results raised the question on how specific treatment measures in acute burn care are met in the absence of standardized guidelines., Material and Methods: A specific questionnaire containing 57 multiple-choice questions was sent to all 22 major burn centers in Germany, Austria and Switzerland. The survey included standards of airway management and ventilation, fluid management and circulation, body temperature monitoring and management, topical burn wound treatment and a microbiological surveillance. Additionally, the distribution of standardized course systems was covered., Results: 17 out of 22 questionnaires (77%) were returned completed. Regarding volume resuscitation, results showed a similar approach in estimating initial fluid while discrepancies persisted in the use of colloidal fluid and human albumin. Elective tracheostomy and the need for bronchoscopy with suspected inhalation injury were the most controversial issues revealed by the survey. Topical treatment of burned body surface also followed different principles regarding the use of synthetic epidermal skin substitutes or enzymatic wound debridement. Less discrepancy was found in basic diagnostic measures, body temperature management, estimation of the extent of burns and microbiological surveillance., Conclusion: While many burn-related issues are clearly not questionable and managed in a similar way in most participating facilities, we were able to show that the most contentious issues in burn trauma management involve initial volume resuscitation, management of inhalation trauma and topical burn wound treatment. Further research is required to address these topics and evaluate a potential superiority of a regime in order to increase the level of evidence., (Copyright © 2016 Elsevier Ltd and ISBI.

Background: Severe burns of hands and arms are complex and challenging injuries. The Standard of care (SOC) - necrosectomy with skin grafting - is often associated with poor functional or aesthetic outcome. Enzymatic debridement (ED) is considered one promising alternative but, until recently, results proved to be highly variable., Methods: Between 04/2014 and 04/2015, 16 patients with deep partial- to full-thickness burns of the upper extremities underwent enzymatic debridement (ED) in our Burn Center and were evaluated for extent of additional surgery, wound healing, pain management and functional parameters., Results: Following ED, no further surgical intervention was required in 53.8 % of the study population. In patients who required surgical treatment, the the skin-grafted area could be reduced by 37.0 % when compared to initial assessment. Time from injury to ED was 24.4 h and patients were able to start physical therapy after 2.0 days but suffered from prolonged wound closure (28.0 days). Regionally administered anesthesia proved to be superior to pain medication alone as pain levels and consumed morphine-equivalent were lower. Post-demission follow-up showed good functional results and pain levels with low scores in two self-report questionnaires (DASH, PRWE-G) but 3 patients reported increased susceptibility to shear stress. Based on these early experiences, we developed a 3-step algorithm for consecutive patients allowing appropriate and individualized treatment selection., Conclusions: We see a potential benefit for ED in the treatment of severely burned hands and forearms but further investigations and proper prospective, randomized controlled trials are needed to statistically support any outlined assumptions.
