Assessing the Effect of Enzymatic Debridement on the Scar Quality in Partial-Thickness Burns to Deep Dermal Burns of the Hand: A Long-Term Evaluation.

Background and Objectives: Burn surgery on the hands is a difficult procedure due to the complex anatomy and fragility of the area. Enzymatic debridement has been shown to effectively remove burn eschar while minimizing damage to the surrounding tissue and has therefore become a standard procedure in many burn centers worldwide over the past decade. However, surprisingly, our recent literature review showed limited valid data on the long-term scarring after the enzymatic debridement of the hands. Therefore, we decided to present our study on this topic to fill this gap. Materials and Methods: This study analyzed partial-thickness to deep dermal burns on the hands that had undergone enzymatic debridement at least 12 months prior. Objective measures, like flexibility, trans-epidermal water loss, erythema, pigmentation, and microcirculation, were recorded and compared intraindividually to the uninjured skin in the same area of the other hand to assess the regenerative potential of the skin after EDNX. The subjective scar quality was evaluated using the patient and observer scar assessment scale (POSAS), the Vancouver Scar Scale (VSS), and the "Disabilities of the Arm, Shoulder, and Hand" (DASH) questionnaire and compared interindividually to a control group of 15 patients who had received traditional surgical debridement for hand burns of the same depth. Results: Between January 2014 and December 2015, 31 hand burns in 28 male and 3 female patients were treated with enzymatic debridement. After 12 months, the treated wounds showed no significant differences compared to the untreated skin in terms of flexibility, trans-epidermal water loss, pigmentation, and skin surface. However, the treated wounds still exhibited significantly increased blood circulation and erythema compared to the untreated areas. In comparison to the control group who received traditional surgical debridement, scarring was rated as significantly superior. Conclusions: In summary, it can be concluded that the objective skin quality following enzymatic debridement is comparable to that of healthy skin after 12 months and subjectively fares better than that after tangential excision. This confirms the superiority of enzymatic debridement in the treatment of deep dermal burns of the hand and solidifies its position as the gold standard.

How did the COVID-19 pandemic affect burn centres in German-speaking countries?

The exponential growth of COVID-19 cases in early 2020 presented a massive challenge for healthcare systems and called for the adaptation of emergency care routines and intensive care capacities. We, therefore, analyzed a possible impact of the COVID-19 pandemic on the general structure and emergency preparedness of burn centers in German-speaking countries through a cross-sectional descriptive survey questionnaire. The survey was conducted for the first time in January 2019 by Al-Shamsi et al. before the beginning of the COVID-19 pandemic. It was performed for a second time in November 2020 during the second wave of COVID-19 infections in German-speaking countries. We noticed a pronounced increase in the preparation for a great number of patients in need of intensive care including the enlargement of overall capacity when necessary. We also showed a notable decrease in the specific preparation for burn disasters and also reduced communication with first responders and other burn centers. To what extent these alterations were caused by the impact the pandemic had on healthcare systems could not be determined in this study and should be the subject of future research.

Comparative Clinical Study of Suprathel® and Jelonet® Wound Dressings in Burn Wound Healing after Enzymatic Debridement.

Following the enzymatic debridement of deep dermal burns, the choice of wound dressing is crucial for providing an adequate environment and suitable conditions for rapid wound healing. As Suprathel® and fatty gauze (Jelonet®) are the most commonly used dressings in burn centers, the aim of this study is to compare Suprathel® and Jelonet® in the treatment of deep dermal burns after enzymatic debridement with respect to wound healing, patient comfort, and pain. A total of 23 patients with deep dermal burns of the hand or foot (mean total body surface area of 4.31%) were included in this prospective, unicentric, open, comparative, and intra-individual clinical study. After enzymatic debridement, wounds were divided into two areas: one was treated with Suprathel® and the other with Jelonet®. Suprathel® remained on the wounds without dressing changes while Jelonet® was regularly changed. Wound healing, infection, bleeding, exudation, time for dressing changes, and pain were documented (from days 2 to 48) after injury. Satisfactory results were obtained in 22 cases; only one patient had to undergo a second debridement followed by skin grafting. No significant difference in time to final wound healing could be observed (18-19 d). Patients reported significantly less pain during the dressing changes for Suprathel® compared to Jelonet®. Furthermore, the wound areas treated with Suprathel® showed significantly less exudation and bleeding. Wound infections rarely occurred in both groups. In conclusion, the authors found that both wound dressings could be used to achieve safe and rapid wound healing after the enzymatic debridement of deep dermal burns of the hands and feet. However, compared to Jelonet®, Suprathel® showed superior results in terms of patient comfort and pain reduction.

The performance of clinical risk scores in the diagnosis of necrotising fasciitis.

OBJECTIVE: Necrotising fasciitis (NF) is a quickly progressing and potentially life-threatening infection, involving the fascia and subcutaneous tissues. The diagnosis of this disease is challenging, especially due to a lack of specific clinical signs. In order to ensure a better and quicker identification of NF patients, a laboratory risk indicator score has been developed for NF (LRINEC). A variant has widened this score by adding clinical parameters (modified LRINEC). This study shows current outcomes of NF and compares the two scoring systems. METHODS: This study was conducted between 2011 and 2018, and included patient demographics, clinical presentations, sites of infection, comorbidities, microbiological and laboratory findings, antibiotic therapies and LRINEC as well as modified LRINEC scores. The primary outcome was in-hospital mortality. RESULTS: A cohort of 36 patients, diagnosed with NF, were included in this study. The mean hospital stay was 56 days (±38.2 days). The mortality rate in the cohort was 25%. The sensitivity of the LRINEC score was 86%. Calculation of the modified LRINEC score showed an improvement of the sensitivity to 97%. The average LRINEC score and modified LRINEC score for patients who died and who survived were equal (7.4 versus 7.9 and 10.4 versus 10.0, respectively). CONCLUSION: The mortality rate of NF remains high. The modified LRINEC score increased the sensitivity in our cohort to 97%, and this scoring system could be supportive in the diagnosis of NF for early surgical debridement.

[Academic Careers in Medicine: a Sex-Related Analysis of Career Goals]. / Akademische Karriere in der Medizin: eine geschlechterbezogene Analyse zu beruflichen Zielen.

AIM OF THE STUDY: For female and male physicians of the clinical-academic mid-level staff, working conditions as well as the attitude towards profession and career play a decisive role. For years, there has been an increasing proportion of women in medicine. Despite this increase, a significant sex incongruence is still evident, especially in academic medicine. The aim of this work was to analyze current opinions of female and male physicians on sex-related aspects for career. METHODS: By means of an online survey, medical mid-level staff from university and peripheral hospitals were asked about professional biographical as well as career-related topics and the data analyzed in terms of the sexes. RESULTS: Compared to their male counterparts, female physicians had lower career goals and mainly aimed to qualify as senior physicians. Women planned to have families and raise children earlier in their careers. Men were more likely to have their professional careers in mind during the same time period. Although only just under 47% of respondents considered an academic career to be worthwhile, 65% continued to rate the acquisition of an academic title highly. When evaluating equal treatment by superiors, female physicians tended to feel disadvantaged in their professional careers compared to male physicians. Thus, physicians rated the treatment by their respective superiors as characterized by the quality of the work (44% for both genders of superiors) or dependent on sympathy (female superiors 30%; male superiors 24%). Female physicians, however, saw a preference for male colleagues in 37% of male superiors. CONCLUSION: Despite a significantly larger proportion of women in medicine for decades, there is still an incongruence in sexes in favor of men in management positions. The professional and private goals of women and men differ significantly depending on their age decade. The academic career per se is increasingly losing importance, although the acquisition of academic degrees still seems to be desirable. Therefore, to improve the future of academic medicine, significant structural changes are needed to enable projectable career paths (e. g., tenure track, assistant professorship, young medical professionals model) for mid-level academic staff.

Nexobrid Treatment for Burn Injuries in Patients With Chronic Obstructive Pulmonary Disease and Home Oxygen Therapy.

There is an increased risk for burn injuries associated with home oxygen therapy of patients with chronic obstructive pulmonary disease (COPD) since 10% to 50% of these patients continue to smoke. Enzymatic eschar removal of facial burns is gaining popularity but intubation of this specific patient group often leads to prolonged weaning and can require tracheostomy. This study dealt with the question if enzymatic debridement in these patients can also be performed in analgosedation. A selective review of the literature regarding burn trauma associated with home oxygen use in patients with COPD was performed, as well as a retrospective analysis of all patients with burn injuries associated with home oxygen use and COPD that were admitted to the study clinic. In the literature, 1746 patients with burns associated with home oxygen use are described, but none of them received enzymatic debridement. In this study, 17 patients were included. All three patients in this study with facial full-thickness burn injuries received enzymatic debridement. The mortality rate in this cohort was 17.6% (3/17). Up to date, there is limited experience performing regional anesthesia debridement in patients with COPD. This is the first manuscript describing the use of enzymatic debridement in patients with COPD and home oxygen therapy. We could confirm other studies that intubation of these patients leads to prolonged ventilation hours and increases the probability for poor prognosis. Therefore, we described the treatment of enzymatic debridement in analgosedation without intubation.

Comparison of Long-Term Skin Quality and Scar Formation in Partial-Thickness Burn Wounds Treated with Suprathel® and epicitehydro® Wound Dressings.

Background and Objectives: Scar formation after burn trauma has a significant impact on the quality of life of burn patients. Hypertrophic scars or keloids can be very distressing to patients due to potential pain, functional limitations, or hyper- or hypopigmentation. In a previous study comparing Suprathel® and the new and cheaper dressing epicitehydro®, we were able to show that pain reduction, exudation, and time until wound-healing of partial-thickness burn wounds were similar, without any documented infections. No study exists that objectively measures and compares skin and scar quality after treatment with Suprathel® and epicitehydro® at present. Materials and Methods: In this study, the scar quality of 20 patients who had been treated with Suprathel® and epicitehydro® was objectively assessed using the Cutometer®, Mexameter®, and Tewameter®, as well as subjectively with the Patient and Observer Scar Assessment Scale, 3, 6, and 12 months after burn injury. Results: In all performed measurements, no significant differences were detected in scar formation after treatment of partial-thickness burn wounds with the two dressings. Conclusions: Both the newer and less expensive wound-dressing epicitehydro® and the well-known wound-dressing Suprathel® resulted in stable wound closure and showed good cosmetic results in the follow-up examinations.

Evaluation of Scar Quality after Treatment of Superficial Burns with Dressilk® and Suprathel®-In an Intraindividual Clinical Setting.

BACKGROUND: Various synthetic and biological wound dressings are available for the treatment of superficial burns, and standard care differs among hospitals. Nevertheless, the search for an ideal wound dressing offering a safe healing environment as well as optimal scar quality while being economically attractive is a continuing process. In recent years, Dressilk®, which consists of pure silk, has become the standard of care for the treatment of superficial burns in our hospital. However, no long-term scar-evaluation studies have been performed to compare Dressilk® with the often-used and more expensive Suprathel® in the treatment of superficial burns. METHODS: Subjective and objective scar evaluations were performed three, six, and twelve months after treatment in patients who received simultaneous treatment of 20 superficial burn wounds with both Suprathel® and Dressilk®. The evaluations were performed using the Vancouver Scar Scale, the Cutometer®, Mexameter®, Tewameter®, and the O2C®. RESULTS: Both dressings showed mostly equivalent results in subjective scar evaluations. In the objective scar evaluations, the wounds treated with Dressilk® showed a faster return to the qualities of non-injured skin. Wound areas treated with the two dressings showed no significant differences in elasticity and transepidermal water loss after 12 months. Only oxygen saturation was significantly lower in wound areas treated with Suprathel® (p = 0.008). Subjectively, wound areas treated with Dressilk® showed significantly higher pigmentation after six months, which was not apparent after 12 months. CONCLUSION: Both wound dressings led to esthetically satisfying scar recovery without significant differences from normal uninjured skin after 12 months. Therefore, Dressilk® remains an economically and clinically interesting alternative to Suprathel® for the treatment of superficial burns.

A clinical comparison of pure knitted silk and a complex synthetic skin substitute for the treatment of partial thickness burns.

Currently, many dressings are commercially available for the treatment of burn wounds. Some of these wound dressings remain on the wound, prevent painful dressing changes, and reduce tissue scarring. Nevertheless, still a wound dressing that is cost-effective, produces good wound healing properties, and has a high patient satisfaction is needed. Standard care of superficial burn wounds differs between burn centres. This study aimed to determine a dressing with easy appliance, accurate pain control, favourable outcome, and cost-effectiveness. Therefore, we compared the widely used but expensive Suprathel with the rather new but much cheaper Dressilk in the clinical setting. In a prospective clinical study, the healing of partial thickness burn wounds after simultaneous treatment with Suprathel and Dressilk was examined in 20 patients intra-individually. During wound healing, pain, infection, exudation, and bleeding were evaluated. A subjective scar evaluation was performed using the Patient and Observer Scar Scale. Both dressings were easy to apply, remained on the wound in place, and were gradually cut back as reepithelisation proceeded and showed similar times to wound closure. Dressing changes were not necessary, and neither infections nor bleeding was detected. Overall exudation and pain were highest in the beginning but declined during the wound-healing phase without significant differences. In the follow-up scar evaluation after 12 months, patients reported overall high satisfaction. Overall, the modern dressings Suprathel and Dressilk (solely made out of pure silk) led to safe wound healing without infection and rapidly reduced pain. There was no need for dressing changes, and they had similar clinical outcomes in scar evaluation. Therefore, both dressings seem to be ideal for the treatment of superficial burns. Because acquisition costs remain one of the main factors in the treatment of burns, Dressilk, which is ~20 times cheaper than Suprathel, remains a good option for the treatment of partial thickness burns.

Lactate-Based Scoring System in the Diagnosis of Necrotizing Fasciitis.

Necrotizing fasciitis (NF) is a rare and quickly progressing infection and leads to 100% mortality if untreated. Quick diagnosis and an early and radical surgical treatment are essential for stopping bacterial progression. Unfortunately, the absence of clear clinical signs makes the diagnosis often challenging. Therefore, we searched for easy determinable predictive laboratory markers for NF. This is the first study which includes lactate values in a new score. A retrospective analysis of patients with NF (n = 44) and patients with erysipelas (n = 150) was performed. Lactate values, patients' demographics, clinical presentations, site of infection, comorbidities, microbiological and laboratory findings, antibiotic therapies, and LRINEC and modified LRINEC scores were analyzed. Logistic regression analysis was used to derive adjusted weights, and final simple point score was assessed with a ROC curve analysis. Patients with NF had a mean age of 57 years and patients with erysipelas 65 years. The median hospital length of stay was 8 and 49 days in patients with erysipelas and NF, respectively. Although only one patient (0.7%) in the group of erysipelas died, the mortality rate of patients with NF was 9/44 (20.5%). The lactate values were statistically significant higher in the NF group, 4.1 vs 2.0 mmol/l (P < .001). The new created CologNe-FaDe-score shows the highest AUC-value with 0.907. With the help of lactate values, the CologNe-FaDe-score consists of easily practicable and highly available parameters, which could sensitize diagnosis.

Comparison of wound healing and patient comfort in partial-thickness burn wounds treated with SUPRATHEL and epictehydro wound dressings.

Among the available dressings for partial-thickness burn wound treatment, SUPRATHEL has shown good usability and effectiveness for wound healing and patient comfort and has been used in many burn centres in the last decade. Recently, bacterial nanocellulose (BNC) has become popular for the treatment of wounds, and many studies have demonstrated its efficacy. epicitehydro , consisting of BNC and 95% water, is a promising product and has recently been introduced in numerous burn centres. To date, no studies including direct comparisons to existing products like SUPRATHEL have been conducted. Therefore, we aimed to compare epicitehydro to SUPRATHEL in the treatment of partial-thickness burns. Twenty patients with partial-thickness burns affecting more than 0.5% of their total body surface area (TBSA) were enrolled in this prospective, unicentric, open, comparative, intra-individual clinical study. After debridement, the wounds were divided into two areas: one was treated with SUPRATHEL and the other with epicitehydro . Wound healing, infection, bleeding, exudation, dressing changes, and pain were documented. The quality of the scar tissue was assessed subjectively using the Patient and Observer Scar Scale. Wound healing in patients with a mean TBSA of 9.2% took 15 to 16 days for both treatments without dressing changes. All wounds showed minimal exudation, and patients reported decreased pain with the only significant difference between the two dressings on day 1. No infection or bleeding occurred in any of the wounds. Regarding scar evaluation, SUPRATHEL and epicitehydro did not differ significantly. Both wound dressings were easy to use, were highly flexible, created a safe healing environment, had similar effects on pain reduction, and showed good cosmetic and functional results without necessary dressing changes. Therefore, epicitehydro can be used as an alternative to SUPRATHEL for the treatment of partial-thickness burn wounds.

Surgical Strategies to Promote Cutaneous Healing.

Usually, cutaneous wound healing does not get impeded and processes uneventfully, reaching wound closure easily. The goal of this repair process is to restore the integrity of the body surface by creating a resilient and stable scar. Surgical practice and strategies have an impact on the course of wound healing and the later appearance of the scar. By considering elementary surgical principles, such as the appropriate suture material, suture technique, and timing, optimal conditions for wound healing can be created. Wounds can be differentiated into clean wounds, clean-contaminated wounds, contaminated, and infected/dirty wounds, based on the degree of colonization or infection. Furthermore, a distinction is made between acute and chronic wounds. The latter are wounds that persist for longer than 4-6 weeks. Care should be taken to avoid surgical site infections in the management of wounds by maintaining sterile working conditions, using antimicrobial working techniques, and implementing the principles of preoperative antibiotics. Successful wound closure is influenced by wound debridement. Wound debridement removes necrotic tissue, senescent and non-migratory cells, bacteria, and foreign bodies that impede wound healing. Additionally, the reconstructive ladder is a viable and partially overlapping treatment algorithm in plastic surgery to achieve successful wound closure.

Macrophage Migration Inhibitory Factor-An Innovative Indicator for Free Flap Ischemia after Microsurgical Reconstruction.

(1) Background: Nowadays, the use of microsurgical free flaps is a standard operative procedure in reconstructive surgery. Still, thrombosis of the microanastomosis is one of the most fatal postoperative complications. Clinical evaluation, different technical devices and laboratory markers are used to monitor critical flap perfusion. Macrophage migration inhibitory factor (MIF), a structurally unique cytokine with chemokine-like characteristics, could play a role in predicting vascular problems and the failure of flap perfusion. (2) Methods: In this prospective observational study, 26 subjects that underwent microsurgical reconstruction were observed. Besides clinical data, the number of blood leukocytes, CRP and MIF were monitored. (3) Results: Blood levels of MIF, C-reactive protein (CRP) and leukocytes increased directly after surgery. Subjects that needed surgical revision due to thrombosis of the microanastomosis showed significantly higher blood levels of MIF than subjects without revision. (4) Conclusion: We conclude that MIF is a potential and innovative indicator for thrombosis of the microanastomosis after free flap surgery. Since it is easy to obtain diagnostically, MIF could be an additional tool to monitor flap perfusion besides clinical and technical assessments.

Effect of comorbidities on clinical outcome of patients with burn injury - An analysis of the German Burn Registry.

BACKGROUND: Severe burn injuries are associated with high morbidity and mortality. Well-implemented scoring systems for patients with major burns exist in the literature. A major disadvantage of these scores is the partial non-consideration of patient-related comorbidities. Published data on this matter is limited to small study cohorts and/or single center studies. Further, the effect of comorbidities on clinical outcome of patients with severe burn injuries has not yet been examined nationwide in a large cohort in Germany. Hence, the aim of this study was to examine the influence of comorbidities on clinical outcome of these patients based on data from the national registry. METHODS: Anonymized data from a total of 3455 patients with documented burns of 1% or more Total Burn Surface Area (TBSA) and over 16 years of age included in the German Burn Registry between 2017 and 2018 were analyzed retrospectively. Data included burn extent, body weight, age, burn depth, inhalation injury, comorbidities, mortality, number of operations and length of hospital stay (LOS). RESULTS: In the logistic regression analysis age (OR 1.07 [1.06-1.09], p < 0.001), TBSA (OR 1.09 [1.08-1.11], p < 0.001), IHT (OR 2.15 [1.44-3.20], p < 0001), third degree burn (OR 2.08 [1.39-3.11], p < 0.001), Chronic Obstructive Pulmonary Disease (COPD) (OR 2.45 [1.38-4.35], p = 0.002) and renal insufficiency (OR 2.02 [1.13-3.59], p = 0.017) influenced mortality significantly. If a patient had more than one comorbidity, mortality was higher and in-hospital length of stay (LOS) longer. Renal insufficiency was significantly (p < 0.001) associated with the most prolonged LOS by 11.44 days. TBSA (p < 0.001), Abbreviated Burn Severity Index (ABSI) > 3 (p < 0.001) and IHT (p = 0.001) correlated with the amount of required surgeries and significantly predicted the need for intubation. Patients with arrhythmia significantly required more surgeries (p = 0.041), whereas patients with COPD required significantly less surgical interventions (p = 0.013). CONCLUSION: Preexisting comorbidities have a significant impact on the clinical outcome of patients with severe burn injuries. Further investigation is warranted in order to supplement existing prognostic scores with new mortality-associated parameters.

Integrative Medicine and Plastic Surgery: A Synergy-Not an Antonym.

BACKGROUND: Integrative medicine focuses on the human being as a whole-on the body, mind, and spirit-to achieve optimal health and healing. As a synthesis of conventional and complementary treatment options, integrative medicine combines the pathological with the salutogenetic approach of therapy. The aim is to create a holistic system of medicine for the individual. So far, little is known about its role in plastic surgery. HYPOTHESIS: We hypothesize that integrative medicine based on a conventional therapy with additional anthroposophic therapies is very potent and beneficial for plastic surgery patients. Evaluation and consequence of the hypothesis: Additional anthroposophic pharmacological and non-pharmacological treatments are promising for all areas of plastic surgery. We are convinced that our specific approach will induce further clinical trials to underline its therapeutic potential.

Is the Parkland formula still the best method for determining the fluid resuscitation volume in adults for the first 24 hours after injury? - A retrospective analysis of burn patients in Germany.

BACKGROUND: R Rapid fluid resuscitation is a crucial therapy during the treatment of patients with extensive burns. In 1968, the Parkland Formula was introduced for the calculation of the estimated volume of the resuscitation fluid. Since then, different methods for the calculation of fluid resuscitation volume have been developed. We aimed to evaluate if the Parkland formula is still the most effective method for fluid resuscitation volume calculation in burn patients. METHODS: In the period between January 2015 and January 2019, data from 569 patients over 16 years old with burns of more than 20% total body surface area (TBSA) and at least 15% TBSA full thickness burns were entered in the German burn registry. The patients were divided into 5 groups (0, +1, -1, +2, -2) according to the volume of the resuscitation fluid they received. Group 0 patients received the amount of fluid calculated according to the Parkland formula (n = 83). The 4 other groups received reduced (-1, -2) or increased (+1, +2) fluid volumes in comparison to the value obtained by the Parkland formula. RESULTS: Patients in Group 0 presented a significantly lower mortality in the first week (4.5%) compared to groups -2 (16.7%) and group +2 (19.5%) (p = 0.021). Furthermore, the mean number of operations in group +2 (5.81) was higher than in group -2 (3.81). Surviving patients from group +2 presented a longer hospital stay (68.1 days) compared to the other groups. Additionally, the logistic regression analysis showed a higher survival of patients in groups -2 and -1 (regression coefficients -0.11 and -0.086; Odds Ratio 0.896 and 0.918; 95% Confidence Interval (CI) 0,411-1.951 and 0.42-2.004). CONCLUSION: In this retrospective study, register based analysis a restrictive fluid regime was associated with a higher survival compared to the liberal Parkland guided fluid regime.

Historical Perspectives on the Development of Current Standards of Care for Enzymatic Debridement.

Background and Objective: The use of plant-based products for burn treatment dates back to 1600 BC. Enzymatic debridement, which can be achieved as non-surgical or conservative debridement, has recently gained increasing attention. Several reviews have been published thus far. However, there has been no historical article including the achievements of the last 20 years, and this is the first review to present the achievements made in the field of enzymatic debridement in the last 20 years. This study aimed to present a historical overview of the development of enzymatic debridement until the present day. Methods: Enzymes from bacteria and plants were initially used for full-thickness burn treatment; however, they did not gain attention. Papain-derived products were the first plant-based products used for enzymatic debridement. Sutilains gained broad use in the 70s and 80s but came off market in the 1990s. Bromelain has been used for burn treatment owing to its strong debriding properties. NexoBrid™ is used as a minimally invasive approach for enzymatic debridement of deep dermal burns. However, its use has been limited due to commercially available bromelain and the presence of four distinct cysteine proteinases. NexoBrid™ involves faster eschar removal together with reduced blood loss, leading to improved long-term outcomes. However, research on nonoperative enzymatic debridement of burns has taken decades and is still ongoing. Results: Overall, the results of our study indicate that necrectomy, which has been used for a long time, remains the standard of care for burns. However, enzymatic debridement has several advantages, such as faster eschar removal, reduced blood loss, and reduced need for skin grafting, especially in cases of facial and hand burns. Enzymatic debridement cannot replace surgical intervention, as the enzyme only works on the surface of the eschar. Enzymatic debridement is not recommended in the early phase of scald burns. Conclusions: Enzymatic debridement has become an integral part of burn therapy and the standard of care in specific burn centers.

Basic life support knowledge in Germany and the influences of demographic factors.

BACKGROUND: In the developed world, cardiovascular diseases still contribute to mortality and morbidity, leading to significantly increased deaths in recent years. Thus, it is necessary for a layperson to provide the best possible basic life support (BLS) until professional help is available. Since information on current BLS knowledge in Germany is not available, but necessary to be able to make targeted improvements in BLS education, we conducted this study. METHODS: A cohort survey using convenience sampling (non-probability) method was conducted with questions found in emergency medicine education. People coming to the emergency room of two big university hospitals located in the South (Munich) and western part (Cologne) of Germany were asked to participate in the survey between 2016 and 2017. Primary outcome measures were the proportion of correct answers for each emergency scenario in relationship to age, region, profession and first-aid training. RESULTS: Altogether 1003 people (504 from Cologne; 499 from Munich) took part in the questionnaire. 54.7% were female and 45.3% were male aging from 19 to 52 with a mean of 37.2 years. Although over 90% had taken part in first aid training, many people were lacking first aid knowledge, with less than 10% choosing the correct frequency for chest compression. Hereby demographic factors had a significant influence (p<0.05) in the given answers (Friedmann-and-Wilcoxon Test). CONCLUSION: Overall, results of our survey indicate a clear lack of BLS knowledge. With this information, targeted measures for improving BLS knowledge should be conducted. Additionally, further studies on the feasibility and efficiency of teaching methods are needed.

Are burn centers in German-speaking countries prepared to respond to a burn disaster? Survey-based study.

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.

Burn first aid knowledge in Germany and the influences of social-economic factors.

BACKGROUND: Optimal management of burns always starts with the first aid. Results of numerous studies carried out in different countries indicated in general a low awareness of first aid of burns irrespective of whether the income of the country was high, middle or low. The aim of the study was to investigate the knowledge in burn first aid in Germany and compare it to an Australian study from 2013. METHODS: From January 2016 until August 2017 patients, visitors and medical personnel in the emergency room of two large hospitals in Southern and the Western part of Germany were asked to take part in a paper based multiple-choice survey. RESULTS: Altogether 1229 people took part in the questionnaire, 588 from Bavaria and 641 from North Rhine-Westphalia; 45,2% males and 54.8% females. Their age ranged from 19 to 52 with a mean of 37.2 years. Hereby participants that had taken part in first aid training and people working in health care had significant more correct answers. Overall, only approximately a third of the given answers were correct. CONCLUSION: Our study suggests that there is room for improvement since only a minority of the German population is familiar with first aid principles dealing with burns. Although more than 40% had taken part in a first aid training, the questioned people gave less correct answers than the Australians in 2013.
