European Burns Association guidelines for the management of burn mass casualty incidents within a European response plan.

BACKGROUND: A European response plan to burn mass casualty incidents has been jointly developed by the European Commission and the European Burn Association. Upon request for assistance by an affected country, the plan outlines a mechanism for coordinated international assistance, aiming to alleviate the burden of care in the affected country and to offer adequate specialized care to all patients who can benefit from it. To that aim, Burn Assessment Teams are deployed to assess and triage patients. Their transportation priority recommendations are used to distribute outnumbering burn casualties to foreign burn centers. Following an appropriate medical evacuation, these casualties receive specialized care in those facilities. METHODS: The European Burns Association's disaster committee developed medical-organizational guidelines to support this European plan. The experts identified fields of interest, defined questions to be addressed, performed relevant literature searches, and added their expertise in burn disaster preparedness and response. Due to the lack of high-level evidence in the available literature, recommendations and specially designed implementation tools were provided from expert opinion. The European Burns Association officially endorsed the draft recommendations in 2019, and the final full text was approved by the EBA executive committee in 2022. RECOMMENDATIONS: The resulting 46 recommendations address four fields. Field 1 underlines the need for national preparedness plans and the necessary core items within such plans, including coordination and integration with an international response. Field 2 describes Burn Assessment Teams' roles, composition, training requirements, and reporting goals. Field 3 addresses the goals of specialized in-hospital triage, appropriate severity criteria, and their effects on priorities and triage. Finally, field 4 covers medical evacuations, including their timing and organization, the composition of evacuation teams and their assets, preparation, and the principles of en route care.

Burn mass casualty incidents in Europe: A European response plan within the European Union Civil Protection Mechanism.

BACKGROUND: Burn care is centralized in highly specialized burn centers in Europe. These centers are of limited capacity and may be overwhelmed by a sudden surge in case of a burn mass casualty incident. Prior incidents in Europe and abroad have sustained high standards of care through well-orchestrated responses to share the burden of care in several burn centers. A burn mass casualty incident in Romania in 2015 sparked an initiative to strengthen the existing EU mechanisms. This paper aims to provide insight into developing a response plan for burn mass casualties within the EU Civil Protection Mechanism. METHODS: The European Burns Association drafted medical guidelines for burn mass casualty incidents based on a literature review and an in-depth analysis of the Romanian incident. An online questionnaire surveyed European burn centers and EU States for burn mass casualty preparedness. RESULTS: The Romanian burn mass casualty in 2015 highlighted the lack of a burn-specific mechanism, leading to the late onset of international transfers. In Europe, 71% of respondents had existing mass casualty response plans, though only 35% reported having a burn-specific plan. A burns response plan for burn mass casualties was developed and adopted as a Commission staff working document in preparation for further implementation. The plan builds on the existing Union Civil Protection Mechanism framework and the standards of the WHO Emergency Medical Teams initiative to provide 1) burn assessment teams for specialized in-hospital triage of patients, 2) specialized burn care across European burn centers, and 3) medevac capacities from participating states. CONCLUSION: The European burn mass casualty response plan could enable the delivery of high-level burn care in the face of an overwhelming incident in an affected European country. Further steps for integration and implementation of the plan within the Union Civil Protection Mechanism framework are needed.

Evaluation of burned hand function after enzymatic debridement.

Hand burns are common injuries that can result in long-term impairment of hand function. Enzymatic debridement (ED) prevents damage to the viable dermis due to the procedure's selectivity and has become an option for obtaining an accurate depth assessment and enabling wound re-epithelialization with less skin graft use. We conducted a prospective study from July 2015 to July 2018, which enrolled patients with deep partial-thickness hand burns and treated them with ED using bromelain. After a specified period, we assessed the patients' hand function, using the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire and the Michigan Hand Outcomes Questionnaire (MHOQ) to assess their disabilities and activities of daily life, respectively. We assessed the hand joint range of motion using a goniometer and assessed scar quality with the Vancouver Scar Scale (VSS). We analyzed 72 patients with 90 burned hands at 3 months and, at the final assessment, 69 patients with 86 burned hands. Fire was the most common cause of the burns. Bromelain allowed for early debridement (73.6% during the first 24 h). At the 3-month evaluation, the mean DASH and MHOQ scores were 2.35 and 97.9%, respectively, with a high inverse correlation between the 2 types of scores (Spearman's rho, -0.78; p < .001). The mean wrist flexion and extension were 85.7 and 80°, respectively, the mean metacarpophalangeal flexion was 88.3°, the proximal interphalangeal (PIP) flexion was 112.9°, and the thumb opposition was 77°. The mean VSS score was 2.87. At the final evaluation, with a minimum follow-up of 391 days, the mean DASH and MHOQ scores were 0.18 and 99.71%, respectively. ED with bromelain in deep partial-thickness hand burns resulted in normal values at 3 months and at over 1 year of follow-up, with complete restoration of function and quality of life and good scar results.

Lactate and lactate clearance in critically burned patients: usefulness and limitations as a resuscitation guide and as a prognostic factor.

OBJECTIVE: Lactate levels to guide resuscitation in critically burned patients are controversial. The purpose of our study was to determine whether absolute lactate values or lower lactate clearance predict mortality, and whether these are useful tools in the resuscitation phase. METHODS: We conducted a prospective, unicentric, observational study of a cohort of 214 burn patients admitted in the Burn Intensive Care Unit. We collected demographic and laboratory data, complications, absolute lactate levels and lactate clearance every 8 h since admission to 72 h. In critical patients we monitored hemodynamic parameters with transpulmonary thermodilution. We used Student's t-test or nonparametric tests, mixed models and Pearson and Spearman methods, Fisher's exact and chi-squared test. RESULTS: Of the 214 patients, 76.6% were male, mean age were 46 ± 15 years and 23.0 ± 19.5% of Total Basal Surface Area (TBSA) burned. Initial mean absolute levels of lactate were 2.02 ± 1.62 mmol/L in survivors vs. 4.05 ± 3.90 mmol/L in nonsurvivors. Initial elevated lactate levels increased mortality (p < .001), length of ICU stay, mechanical ventilation and shock. In the subgroup of burned TBSA < 20%, lowering the lactate cut-off point from 2.0 to 1.8 mmol/L improved the mortality prediction (OR:9.3). We found no relationship between lactate clearance in the first 24 h and mortality. In more severe patients (> 20% TBSA burned and initial lactate levels > 2), a good correlation was found between lactate and cardiac index; but not with intrathoracic blood volume index (ITBVI). Patients with low ITBVI preload (< 600 mL/m2) did not show significant differences in lactate clearance compared with those with ITBVI > 600. CONCLUSIONS: Initial elevated lactate levels are a factor of poor prognosis and the cut-off point that best predicts mortality should be adjusted in the patients with TBSA burned < 20%. The global clearance of lactate in the first 24 h, unlike what occurs in other injuries, does not correlate with mortality. Monitoring lactate can ensure adequate peripheral perfusion during resuscitation with lower than normal fluid preload values.

Eschar removal by bromelain based enzymatic debridement (Nexobrid®) in burns: European consensus guidelines update.

INTRODUCTION: Bromelain-based Enzymatic Debridement has been introduced as an additional concept to the burn surgeon's armamentarium and is best indicated for mid-to deep dermal burns with mixed patterns. Increasing evidence has been published focusing on special regions and settings as well as on limitations of Enzymatic Debridement to improve patient care. To better guide Enzymatic Debridement in view of the increasing experience, there is a need to update the formerly published consensus guidelines with user-orientated recommendations, which were last produced in 2017. METHODS: A multi-professional expert panel of plastic surgeons and burn care specialists from twelve European centers was convened, to assist in developing current recommendations for best practices with use of Enzymatic Debridement. Consensus statements were based on peer-reviewed publications and clinical relevance, and topics for re-evaluation and refinement were derived from the formerly published European guidelines. For consensus agreement, the methodology employed was an agreement algorithm based on a modification of the Willy and Stellar method. For this study on Enzymatic Debridement, consensus was considered when there was at least 80 % agreement to each statement. RESULTS: The updated consensus guidelines from 2019 refer to the clinical experience and practice patterns of 1232 summarized patient cases treated by the panelists with ED in Europe (2017: 500 cases), reflecting the impact of the published recommendations. Forty-three statements were formulated, addressing the following topics: indications, pain management and anesthesia, large surface treatment, timing of application for various indications, preparation and application, post-interventional wound management, skin grafting, outcome, scar and revision management, cost-effectiveness, patient´s perspective, logistic aspects and training strategies. The degree of consensus was remarkably high, with consensus in 42 out of 43 statements (97.7%). A classification with regard to timing of application for Enzymatic Debridement was introduced, discriminating immediate/very early (≤12 h), early (12-72 h) or delayed (>72 h) treatment. All further recommendations are addressed in the publication. CONCLUSIONS: The updated guidelines in this publication represent further refinement of the recommended indication, application and post-interventional management for the use of ED. The published statements contain detailed, user-orientated recommendations aiming to align current and future users and prevent pitfalls, e.g. for the successful implementation of ED in further countries like the USA. The significance of this work is reflected by the magnitude of patient experience behind it, larger than the total number of patients treated in all published ED clinical trials.

Organización de unidades de quemados durante la pandemia por COVID-19: experiencia de 5 unidades de quemados / Organization of burn units during the COVID-19 pandemic: experience of 5 burn units

El 11 de marzo de 2020, el brote del coronavirus SARS-Cov-2 fue declarado pandemia global, suponiendo un reto para todos los sistemas sanitarios del mundo. Por este motivo, desde los distintos estados se ha llevado a cabo una reorganización de los sistemas nacionales de salud para lidiar con esta enfermedad. En este contexto han surgido nuevas recomendaciones en el manejo del paciente quirúrgico, posponiéndose las cirugías electivas. No obstante, la naturaleza urgente del tratamiento del paciente gran quemado es un hecho que justifica su tratamiento quirúrgico, incluso en casos afectados por el virus. La coincidencia de la precocidad e intensidad con que la pandemia afectó a España con la existencia de una escasa evidencia en cuanto a la organización de las unidades de quemados en este nuevo contexto, propició que la organización de cada centro surgiera de novo en función de sus circunstancias particulares. En este trabajo, exponemos los esquemas organizativos y la experiencia de 5 unidades de quemados, 4 españolas y 1 chilena, en su adaptación al contexto de la pandemia por COVID-19

On March 11th, a pandemic situation caused by the virus SARS-Cov-2 was declared, challenging health-care systems all over the world. Therefore, a reorganization of national health-care systems had to be performed in order to deal with this disease. In this context, new recommendations have appeared for the management of surgical patients, postponing elective surgeries. However, urgency in the treatment of burn patients is justified, even in those cases affected by the virus. The coincidence of the precocity and intensity with which the pandemic affected Spain, with the existence of scarce evidence regarding burn unit organization, caused that reorganization of each center had to be performed from scratch, adapting their particular circumstances. In this article, we expose the organizational schemes and the experience of 5 burn units, 4 in Spain and 1 more in Chile, in their adaptation to the COVID-19 pandemic

Perspectiva quirúrgica de los resultados del desbridamiento enzimático en grandes quemados / Surgical perspective of enzymatic debridement outcomes in major burns

INTRODUCCIÓN Y OBJETIVO: El desbridamiento enzimático ha demostrado ser eficaz y rápido en su aplicación sobre quemaduras, a la vez que conservador con el tejido sano. Su uso sobre quemaduras inferiores al 15% ha mostrado reducir la cantidad de injertos, el sangrado y las escarotomías quirúrgicas. El objetivo de este estudio es comparar 2 grupos de pacientes grandes quemados, uno tratado mediante desbridamiento enzimático frente a otro tratado mediante tratamiento estándar, y su impacto en la estancia hospitalaria, necesidades de escarotomías, tiempo hasta desbridamiento, uso de hemoderivados y cantidad de cirugías durante el ingreso. MATERIAL Y MÉTODO: Estudio de cohortes retrospectivas con 197 pacientes (SCQ 20-50%), mayores de 18 años, tratados entre 2012 y 2017, con 2 grupos: 32 pacientes tratados con Nexobrid® para el desbridamiento enzimático, y 165 pacientes en el grupo control con desbridamiento tangencial convencional. Ambos homogéneos para SCQ, edad, sexo, mecanismo de lesión y comorbilidades. RESULTADOS: La edad media fue de 48.4 ± 19.4 años, con una SCQ media de 29.5 ± 9.4%. Observamos disminución del tiempo hasta el inicio del desbridamiento de la quemadura (5.1 ± 4.9 días en el grupo control frente a 0.8±0.9 en el grupo de desbridamiento enzimático, p < 0.05). El grupo de Nexobrid® presentó una reducción de la cantidad de tiempos quirúrgicos durante su ingreso, siendo de 1.9±2.0 frente a 2.6±2.1 en el grupo control. El uso de hemoderivados se redujo en un 95% durante el desbridamiento. La necesidad de escarotomías se redujo un 60%. Finalmente, el grupo de Nexobrid® tuvo un 36% menos de estancia en la Unidad de Quemados Críticos, con diferencias estadísticamente significativas. CONCLUSIONES: La aplicación precoz del desbridamiento enzimático en grandes quemados (20-50% SCQ), permite la escarectomía completa del paciente reduciendo la necesidad de hemoderivados, el número de tiempos quirúrgicos, las escarotomías y la estancia en la unidad de cuidados intensivos

BACKGROUND AND OBJECTIVE: Use of enzymatic debridement has demonstrated be fast and efficient after its application over burn wounds, being more delicate over healthy tissue. Its use in burns under 15% TBSA has shown less grafting procedures, bleeding and surgical escharotomies. The aim of this study was compare 2 groups of major burns; one treated by enzymatic debridement and other treated by standard of care. Length of stay, escharotomies, time until debridement, use of blood packs and number of surgeries during hospitalization were evaluated. METHODS: A retrospective cohort study was designed with 197 patients (TBSA 20-50%), older than 18 years old, treated between 2012 and 2017, and divided in 2 groups: 32 patients were debrided using Nexobrid®, and 165 patients were included in the control group. Both groups were homogeneous for TBSA, age, gender, mechanism and comorbidities index. RESULTS: Mean age was 48.4±19.4 years, with a 29.5±9.4% of TBSA. A reduction of the number of days until the burns debridement were found, with 5.1±4.9 in the control group and 0.8±0.9 days in the enzymatic debridement group (p < 0.05). The number of surgeries during the hospitalization were less in the Nexobrid® group, with a reduction of 2.6±2.1 surgeries to 1.9±2.0. The number of blood packs was a 95% lower in the enzymatic debridement, and a 60% less escharotomies were observed. Finally, a shorter length of stay in the intensive care unit were found in the Nexobrid® group, with 36% less days, this difference were statistically significant. CONCLUSIONS: Early application of enzymatic debridement in major burns (20-50% TBSA) allows a complete removal of eschar reducing the blood packs use, number of surgeries, escharotomies and length of stay in the intensive care unit

Estudio económico del tratamiento de las quemaduras térmicas mediante desbridamiento enzimático; papel determinante de la estancia hospitalaria / Economics of thermal burns treatment by enzymatic debridement; the pivotal role of hospital length-of-stay

Introducción y Objetivo: El desbridamiento enzimático con Nexo-brid(R), concentrado de enzimas proteolíticas enriquecidas en bromelaína, supone un avance terapéutico importante. El objetivo de este trabajo es realizar un análisis económico del tratamiento de quemaduras térmicas con Nexobrid(R), investigando los determinantes del coste. Material y Método: Analizamos retrospectivamente los recursos utilizados en el tratamiento mediante desbridamiento enzimático con Nexobrid(R) de las heridas por quemadura térmica de espesor parcial superficial/profundo y completo, de los pacientes adultos ingresados consecutivamente en nuestro hospital entre 2014 y 2016. Investigamos la participación de cada recurso en el coste total para algunos subgrupos de pacientes. Resultados: Estudiamos a 71 pacientes con edad media de 45.4 años; el 73.2% varones. Las lesiones fueron en un 64.8% por llama el 77.5% fueron quemaduras dérmicas profundas y la superficie corporal total afectada fue ≤10% en el 70.4%. El coste medio estimado por paciente fue de 20.844€ (rango: 2.192€ - 145.198€), correspondiendo el 68,1% a la estancia en la Unidad de Quemados Críticos y en hospitalización convencional y el 13.9% al uso de Nexobrid(R). El coste medio de las quemaduras subdérmicas fue significativamente superior al de las dérmicas profundas (p=0.0004) y dérmicas superficiales (p=0.013). El porcentaje de superficie corporal total quemada marcó una diferencia significativa del coste (p<0.0001), observando una correlación importante (R2 = 0.77) con la estancia hospitalaria total. Conclusiones: La estancia hospitalaria en Unidad de Quemados Críticos y en hospitalización convencional constituye el principal determinante del coste del tratamiento de las quemaduras térmicas de espesor parcial superficial/profundo y completo mediante desbridamiento enzimático (48,7% y 19,4% del total, respectivamente); Nexobrid(R)contribuye sólo con un 13,9% del total. Asimismo, el porcentaje de superficie corporal total quemada muestra una fuerte correlación con la estancia hospitalaria

Background and Objective: Enzymatic debridement with Nexo-brid(R), a concentrate of proteolytic enzymes enriched in bromelain, represents an important therapeutic breakthrough. Our aim is to carry out an economic analysis of the treatment of thermal burns with Nexobrid(R), researching the cost determinants. Methods: We analyzed retrospectively the resources used in the treatment by enzymatic debridement with Nexobrid(R) of wounds by thermal burn of superficial/deep partial and full-thickness, of the adult patients admitted consecutively in our hospital (2014-2016). Participation of each resource in total cost was analyzed for some patient subgroups. Results: Seventy one patients were analyzed: age: 45.4 years; men: 73.2%; flame wound: 64.8%; full-thickness burn: 77.5%; Total Body Surface Area ≤10%: 70.4%. Average cost per patient was estimated in €20.844 (range: €2.192-€145.198); 68.1% was associated to length of Critical Burn Unit and conventional hospital stay. Cost of full-thickness burns was significantly higher than that of the superficial (p=0.013) and deep partial ones (p=0.0004). Total Body Surface Area leaded a significant cost difference (p<0.0001), showing a high correlation (R2=0.77) with the total hospital length of stay. Conclusions: Hospital length of stay (Critical Burn Unit and conventional hospital) is the main cost determinant of the treatment of thermal burns of superficial/deep partial and full-thickness with enzymatic debridement (48.7% and 19.4%, respectively); Nexobrid(R) contributes only with 13.9% of total cost. Likewise, total body surface area shows a strong correlation with length of stay

Evaluación de tiempos quirúrgicos y transfusiones en pacientes quemados tratados con desbridamiento enzimático / Evaluation of surgical times and transfusions in burn patients treated with enzymatic debridement

Introducción y Objetivo. En los últimos años se han publicado resultados que demuestran un desbridamiento enzimático rápido, eficaz y específico de tejidos quemados con el uso de Nexobrid(R) (Mediwound, Alemania), producto compuesto por un concentrado de enzimas proteolíticas enriquecidas con bromelaína. En este estudio comparamos el uso de Nexobrid(R) como desbridante enzimático frente a un Grupo Control con tratamiento estándar, con el objetivo de evaluar; en función de la superficie corporal quemada (SCQ), la cantidad de intervenciones quirúrgicas realizadas, la colonización del lecho quirúrgico, la necesidad de escarotomías, así como los requerimientos transfusionales de los pacientes tratados. Material y Método. Estudio retrospectivo con 65 pacientes, edad media de 46.87 años, tratados con Nexobrid(R) entre septiembre de 2015 y diciembre de 2016. Comparamos con un grupo control de 177 pacientes, edad media de 48.24 años, intervenidos mediante desbridamiento tangencial desde enero a diciembre de 2014. El Grupo Control presenta unas características homogéneas a las del Grupo Nexobrid(R). Ambos grupos fueron estratificados en función de su SCQ mayor o menor del 15%. Resultados. Encontramos diferencias estadísticamente significativas (p <0.01) con un menor número de días desde la quemadura y el ingreso hasta la cirugía para el Grupo Nexobrid(R) independientemente de la SCQ. Obtuvimos diferencias estadísticamente significativas para la cantidad de cirugías (p <0.01) en el subgrupo de SCQ <15%. Evaluamos la colonización sin obtener diferencias estadísticamente significativas entre los grupos. El número de escarotomías en el Grupo Nexobrid(R) fue significativamente menor que en el Grupo Control para las poblaciones con SCQ ≥15%. Los requerimientos transfusionales fueron menores en el Grupo Nexobrid(R) frente al Grupo Control en los pacientes con SCQ ≥ 15% (p <0.05). Conclusiones. Nexobrid(R) permite reducir el número de cirugías y el tiempo hasta el primer desbridamiento sin aumentar la tasa de colonización respecto al Grupo Control. El desbridamiento enzimático precoz reduce la necesidad de escarotomías en pacientes con SCQ ≥15%. Finalmente, reduce la necesidad de transfusión sanguínea en pacientes con SCQ mayor del 15% (AU)

Background and Objective. During the last years, results have been published demonstrating fast, efficient and specific enzymatic debridement of burned tissues with the use of a concentrate of proteolytic enzymes enriched with bromelain (Nexobrid(R), Mediwound, Germany). In this study we compare the use of Nexobrid(R) against a Control Group with standard treatment, in order to evaluate; the number of surgical procedures performed, the colonization of the surgical bed, the need for scarotomies, as well as the number of transfusions of the treated patients according to the total burned surface area (TBSA). Methods. We conduct a retrospective study evaluating 65 patients (mean age 46.87 years) treated with Nexobrid(R) between September 2015 and December 2016. We compare this population with a control group of 177 patients (mean age 48.24 years) treated with tangential excision from January to December 2014. The Control Group was homogeneous to Nexobrid(R) Group. Both groups were stratified according to their TBSA in 2 groups: more or less than 15%. Results. We found lesser number of days from burn and hospital admission to the first debridement for the Nexobrid(R) Group regardless of the burned body surface. Statistically significant differences were obtained for the number of surgeries (p <0.01) in the subgroup with <15% TBSA. We evaluated the colonization without obtaining statistically significant differences between the groups. The number of scarotomies carried out in the Nexobrid(R) Group was significantly lower than in the Control Group when comparing the populations with ≥15% TSBA. The transfusion requirements were lower in the Nexobrid(R) Group compared to the Control Group in patients with ≥15% TBSA (p <0.05). Conclusions. The use of Nexobrid(R) allows reducing the number of surgeries and the time elapsed to first debridement without increasing the rate of colonization when compared to the Control Group. Early enzymatic debridement reduces the need for scarotomies in ≥15% TBSA patients. The use of Nexobrid (R) reduces the need for blood transfusion in patients with ≥15% TBSA (AU)

Guía clínica de consenso en el uso de desbridamiento enzimático en quemaduras con NexoBrid(R) / Consensus guideline about the use of the enzymatic debridement in burn injuries with NexoBrid(R)

Introducción y Objetivo. El desbridamiento precoz es la base del tratamiento de las quemaduras. La retirada de la escara durante las primeras 72 horas es la mejor opción para reducir la estancia hospitalaria y los eventos infecciosos. Sin embargo, en muchas ocasiones se compromete la dermis viable necesaria para obtener los mejores resultados estéticos y funcionales, obligando a injertar el lecho. Hay numerosa evidencia acerca de la reducción de las tasas de injerto, la pérdida hemática y el número de intervenciones cuando se utiliza un desbridante enzimático, NexoBrid(R). El objetivo de esta publicación es establecer una guía clínica basada en la opinión de los expertos españoles. Material y Método. Se diseñó un panel de 7 expertos de las principales Unidades de Quemados españolas, con más de 350 pacientes tratados, que discutió las diferentes fases del tratamiento con NexoBrid(R) para obtener una guía clínica de consenso acerca de la indicación, uso y manejo del desbridamiento enzimático. Resultados. Se alcanzó un alto nivel de consenso, con más del 70% de acuerdo en cada una de las fases de tratamiento. Todos los aspectos del tratamiento con NexoBrid(R) fueron discutidos durante la reunión, así como las indicaciones y limitaciones de su uso, incluyendo todas las nuevas evidencias publicadas hasta el momento. También las diversas opciones utilizadas por los diferentes centros de quemados españoles, alcanzando una recomendación global sobre su uso. Conclusiones. Se redactó un documento como guía clínica preliminar sobre el uso de NexoBrid(R) hasta que se creen nuevas guías basadas en evidencia. No existe ningún otro consenso similar publicado hasta el momento (AU)

Background and Objective: Early debridement is considered the keystone of the burn injuries treatment. It is well known that the eschar removal during the first 72 hours is the best option to reduce the hospital stay and the infectious events. However this treatment compromise the preservation of viable dermis, needed to reach the best functional and aesthetic outcome, therefore grafting the wound bed is mandatory. There is increasing evidence that enzymatic debridement with NexoBrid(R) is showing a reduction in the grafting rate, the blood loss and the number of surgical excisions. The objective of this consensus meeting is providing guidelines based in Spanish experts experiences. Methods. A panel of 7 experts from the main Spanish Burn Units were design, with more than 350 patients treated by them, where the different statements were discussed, trying to get a consensus guideline of the indication, use and management of NexoBrid(R). Results. A high level agreement was stated. All the aspects of NexoBrid(R) treatment were discussed showing an agreement of 70%, as well as the indications and limitations of its use. All new evidence published so far this paper was included. Different treatment options used by the Spanish Burn Centers were discussed, showing a global recommendation in their use. Conclusions. A consensus document was created as a preliminary guideline for the NexoBrid(R) use until further guidelines are available. There is no other consensus guideline published so far this document (AU)

Disminución de la necesidad de cobertura con injertos y baja tasa de cicatrización hipertrófica en quemaduras tras desbridamiento enzimático / Reduced need for grafting and low incidence of hypertrophic scarring in burns after enzymatic debridement

Introducción y Objetivo. El tratamiento clásico de las quemaduras se basa en la eliminación precoz de la escara; sin embargo, el desbridamiento tangencial de las quemaduras mixtas y profundas retira tejidos dérmicos viables, obligando a la cobertura con autoinjertos. El desbridamiento enzimático con enzimas proteolíticos enriquecidos con Bromelaína (Nexobrid®) mantiene restos dérmicos que pueden permitir la reepitelización por sí misma de la quemadura. Evaluamos el uso en nuestra unidad de Nexobrid® (MediWound Ltd., Israel) en quemaduras mixtas y dérmicas profundas, valorando la capacidad de reepitelización tras su uso, la tasa de injerto en los pacientes tratados, y la aparición de cicatrización hipertrófica. Pacientes y Método. Evaluamos retrospectivamente 36 pacientes tratados con Nexobrid® entre enero de 2015 y febrero de 2016, 11 mujeres y 25 varones con una media de edad de 42.89 años. La superficie corporal quemada media fue del 7.47% y la diagnosticada como profunda del 6.42%.Todos los pacientes presentaron quemaduras profundas con necesidad de cirugía para su desbridamiento y cobertura con injertos. Resultados. Tras el desbridamiento enzimático solo el 36.1% de los pacientes (13 de 36) requirió cobertura con injertos (p < 0.001).La superficie injertada fue tan solo del 2.67% frente al 4.98% que fue desbridada enzimáticamente (p < 0.001). A pesar de que el tiempo hasta la epitelización total de las quemaduras se alargó hasta los 25.69 días, tan solo un 11.1% de los pacientes desarrolló cicatriz hipertrófica. Conclusiones. Nexobrid® permite el desbridamiento completo de las quemaduras mixtas y dérmicas profundas disminuyendo el porcentaje de pacientes que requieren autoinjertos y la superficie injertada, con bajas tasas de cicatrización hipertrófica (AU)

Background and Objective. Early burn scar removal is the standard of care for burn patients; excisional debridement, however, often leads to excision of dermal remnants, making autografting unavoidable. Enzymatic debridement with proteolytic enzymes enriched in Bromelain (Nexobrid®) leaves these dermal remnants to allow spontaneous healing of partial thickness burns. This study evaluates if Nexobrid® (MediWound Ltd., Israel) reduces the need for surgery and autografting in intermediate and deepdermal burns, the reduction in the excised and grafted area, and the development of hypertrophic scarring. Patients and Methods. We conduct a prospective study between January 2015 and February 2016 evaluating 36 patients (11 females, 25 males) whose mean age was 42.89, with burns covering a mean of 7.47% of their total body surface area (6.42% deep burns). All patients would need excision and autografting as their previous standard of care. Results. After enzymatic debridement, only 13 patients (36.1%) needed surgery (p < 0.001). The area of burns excised and grafted was reduced (2.67% vs. 4.98% p < 0.001). Since wound closure was delayed until 25.69 days, only 11.1% of the patients developed hypertrophic scars. Conclusions. Nexobrid® allows scar removal in deep-dermal and intermediate burns, reducing the need of surgery and the grafted body surface area, while achieving good scars (AU)

[Energy expenditure prediction equations in burn patients; bibliographic review]. / Estimación del gasto energético en el paciente quemado mediante la utilización de ecuaciones predictivas; revisión bibliográfica.

INTRODUCTION: The estimation of the caloric requirements of the burn patient is based on the measurement of his resting energy expenditure (REE) via indirect calorimetry, which is not available in all Burn Units, or its estimation by means of predictive equations. GOALS: we analyze the history and state of art of the use of REE predictive equations in burn patients, and determine their validity. METHODS: bibliographic review of the studies and reviews written in English and Spanish between 1989 and 2013. RESULTS: More than 190 equations have been designed to estimate energy expenditure. These equations can be imprecise because they are based on measurements with a heterogeneous methodology and in heterogeneous groups. We describe the different parameters that are used in the different equations (stress and activity factors, total burn surface area, post-burn day, lean body mass), the influence of age in the calculation of the caloric requirements, and the most commonly used equations nowadays. We also describe the articles that evaluate the accuracy of the predictive equations when compared to REE indirect calorimetry measurements. CONCLUSIONS: Predictive equations are not precise in general in the burn patient. Until more accurate predictive equations are developed, we recommend calculation of the nutritional requirements in burn patients based on the energy expenditure measurement via indirect calorimetry.

Introducción: La valoración de las necesidades calóricas del paciente quemado se ha basado en la medición del gasto energético en reposo (GER) mediante calorimetría indirecta, no siempre disponible en las unidades de quemados, o en su estimación mediante el uso de ecuaciones predictivas. Objetivos: analizar la historia y estado del arte del uso de las ecuaciones predictivas de GER en el paciente quemado crítico, y determinar su validez. Métodos: revisión bibliográfica de estudios y revisiones en español y en inglés entre 1989 y 2013. Resultados: Se han diseñado más de 190 ecuaciones para estimar el gasto energético que pueden ser imprecisas por estar basadas en mediciones con metodología heterogénea y en grupos heterogéneos. Describimos los distintos parámetros que aplican las distintas fórmulas predictivas (factores de estrés y de actividad, superficie corporal quemada, tiempo desde la lesión, masa corporal magra), la influencia de la edad en el cálculo de las necesidades calóricas y las fórmulas más utilizadas en el momento actual. También describimos los artículos que evalúan exactitud de las fórmulas cuando se comparan con mediciones mediante calorimetría indirecta. Conclusiones: Las ecuaciones predictivas son poco precisas en general en el paciente quemado. Hasta que se desarrollen ecuaciones predictivas más precisas, recomendamos calcular los requerimientos nutricionales de los pacientes quemados basándose en la medición del gasto energético por calorimetría indirecta.

Introduction: The estimation of the caloric requirements of the burn patient is based on the measurement of his resting energy expenditure (REE) via indirect calorimetry, which is not available in all Burn Units, or its estimation by means of predictive equations. Goals: we analyze the history and state of art of the use of REE predictive equations in burn patients, and determine their validity. Methods: bibliographic review of the studies and reviews written in English and Spanish between 1989 and 2013. Results: More than 190 equations have been designed to estimate energy expenditure. These equations can be imprecise because they are based on measurements with a heterogeneous methodology and in heterogeneous groups. We describe the different parameters that are used in the different equations (stress and activity factors, total burn surface area, post-burn day, lean body mass), the influence of age in the calculation of the caloric requirements, and the most commonly used equations nowadays. We also describe the articles that evaluate the accuracy of the predictive equations when compared to REE indirect calorimetry measurements. Conclusions: Predictive equations are not precise in general in the burn patient. Until more accurate predictive equations are developed, we recommend calculation of the nutritional requirements in burn patients based on the energy expenditure measurement via indirect calorimetry (AU)
