The epidemiological characteristic and trends of burns globally

Bridging frailty and burns: Defining acute burn injury as a cause of long-term frailty

Although our understanding of frailty has evolved and multiple indices have been developed, the impact of burn injuries on long-term health has been overlooked. With over 11 million annual cases globally, burns affect all demographics, although socioeconomic disparities are evident. With survival rates improved, morbidity among survivors is becoming more evident, and shows similarity to predictors of frailty. Some of the chronic effects of burns, including mental health issues and increased risks of disease, mirror frailty markers. Studies show burn survivors have lower life expectancy, independent of burn severity. Integrating burn history into frailty assessments and establishing specialized long-term care can mitigate this frailty risk. Improved interdisciplinary follow-up and research are vital for enhancing burn survivors' quality of life and longevity.

The association of stress perception on anxiety, depression and sleep quality in parents of children with burns: The moderating effect of social support

OBJECTIVE

Few studies have explored the mental health status of parents of children with burns and the moderating effect of social support on them.

METHODS

A survey was performed with parents of 112 burn-injured children at a burn center in China. Their perceived stress, anxiety, depression, sleep quality, and social support were measured by the Chinese Perceived Stress Scale, Hospital Anxiety and Depression Scale, Pittsburgh Sleep Quality Index, and Perceived Social Support Scale.

RESULTS

➀ The prevalence of anxiety (46.43%), depression (52.67%) and poor sleep quality (43.75%) of parents indicated that they experienced emotional and sleep disorders;➁ The perceived stress was positively correlated with sleep quality, anxiety and depression（P＜0.01), and negatively correlated with perceived social support (p＜0.05); ➂ Social support had a significant moderating effect on their perceived stress and anxiety, depression, but not on their sleep quality. With high social support, parental perceived stress had a significant positive association on anxiety and depression, while with low perceived social support, parental perceived stress had no significant association on anxiety and depression.

CONCLUSION

Parents of burned children had increased stress, obvious symptoms of anxiety and depression, and poor sleep quality. Social support had a significant buffering effect on them under low pressure, and high pressure will hinder the buffering effect of social support on stress. Therefore, the ideal services to improve mental health should be provided for them to face different levels of stress.

Recovery of functional independence following major burn: A systematic review

BACKGROUND

Major burn injury, despite advancements in care and prevention, can have a profound impact on long-term morbidity, affecting quality of life and socioeconomic standing. We aim to explore factors predicting recovery of independence, the expected rate and time in majorly burned patients, and the measures of progress used.

METHOD

A systematic search of four databases (MEDLINE, EMBASE, COCHRANE, CINAHL) was conducted for studies reporting outcomes pertaining to physical ability indicative of independent function in adult (>15 y) cohorts who had suffered a major burn (>20% TBSA) up to 30 years after treatment in a developed specialised burn service. Data extracted included factors affecting rate of and time to achievement of function in five independence domains, as well as the outcome measures used.

RESULTS

21 eligible studies were included comprising 1298 major burns survivors with a combined mean age of 39.6 y and a mean TBSA of 25.8%. The most significant recurring factors impacting recovery of independent function were older age, female gender, burn severity, prolonged ICU and hospital admission, preceding mental health conditions, and post-acute psychological issues. Exercise-based rehabilitation conferred benefits on major burn patients even over 2 years following injury. Discharge to independent living from hospital occurred in 27% to 97% of patients, while reported return to work rates varied from 52% to 80%. Burns Specific Health Scale-Brief, Functional Independence Measure, and Physical Composite Score (SF-36) were the most widely used outcome scoring systems.

CONCLUSION

Major burn survivors have protracted recovery with potential for persistent chronic impairments, remaining consistently below baseline levels of function. Non-modifiable factors such as age and gender, and disease characteristics such as burn size with associated physical, physiological and psychosocial sequelae are contributory. Further research is required to explore achievement of specific milestones of major burn and polytrauma critical care patients, while early targeted rehabilitation addressing physical, psychological, and vocational needs has promising potential benefit.

Demoralization syndrome in burn patients: A cross-sectional study

AIMS

To investigate the status of demoralization syndrome and the factors affecting demoralization in burn patients.

METHODS

This study employed a cross-sectional research design and utilized a face-to-face questionnaire to gather data from adult burn patients with burn depths classified as second-degree or higher. The Demoralization Scale Mandarin Version, the Perceived Social Support Scale, the Herth Hope Index, and the Medical Coping Method Questionnaire were used to assess the level of demoralization, perceived social support, sense of hope, and coping strategies, respectively. General information, including socio-demographic data and disease characteristics, were collected. The patients' level of demoralization was categorized as the mean ± 1 standard deviation of the DS-MV scores. The data was analyzed using IBM SPSS 26.0 software to explore the relationship between the variables.

RESULTS

This study included 381 burn patients with a mean DS-MV score of 34.62 ± 18.319. Of these, 66 (17.3%) had mild demoralization, 241 (63.3%) had moderate demoralization, and 74 (19.4%) had severe demoralization. Cause of burn, total burn area, average monthly income of the individual, occupation, sense of hope, perceived social support, and medical coping strategies were the important factors associated with the severity of demoralization in burn patients.

CONCLUSIONS

Patients with burn injuries exhibit a notable prevalence and severity of demoralization indicating focused attention. By considering associated risk factors, healthcare professionals can devise and execute tailored intervention strategies aimed at mitigating the occurrence and intensity of demoralization in burn patients.

The role of multiplatform messaging applications in burns care and rehabilitation: A systematic review

BACKGROUND

Multiplatform messaging applications also referred to as cross-platform instant messaging play an important role in delivery of healthcare and education with its low cost, ease of use and accessibility.

AIM

To evaluate the existing evidence regarding the use of multiplatform messaging applications in facilitating consultations and decision-making processes in the context of burns care, as well as to assess the impact of such applications on burns care and rehabilitation.

METHOD

A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines and PROSPERO protocol CRD42021265203. The CASP and JBI tools were used to evaluate the quality of the studies. Eight hundred fifty-three papers were retrieved from PubMed, CINAHL, Scopus, EMBASE and LILACS published up to July 2022 (updated August 2023) with no time restrictions applied.

RESULTS

An analysis of the seven studies included in this review, inclusive of 16 Multiplatform messaging applications, revealed six themes. These encompassed the utilization of social media for directing and managing clinical practice, as a mode of communication, for evaluating the quality-of-care provision, for investigating available platforms and their technological features, measuring quality of life and for examining issues related to confidentiality.

CONCLUSION

Multiplatform messaging applications offer a solution for individuals with burn injuries to stay in direct contact with burn specialist clinicians for their follow-up and subsequent rehabilitation phase of recovery.

Revalidating the prognostic relevance of the Abbreviated Burn Severity Index (ABSI): A twenty-year experience examining the performance of the ABSI score in consideration of progression and advantages of burn treatments from a single center in Vienna

BACKGROUND

The Abbreviated Burn Severity Index (ABSI) is a five-variable scale to help evaluate burn severity upon initial assessment. As other studies have been conducted with comparatively small patient populations, the purpose of this study is to revalidate the prognostic relevance of the ABSI in our selected population (N = 1193) 4 decades after its introduction, considering the progress in the treatment of severe burn injuries over the past decades. In addition, we evaluate whether comorbidities influence the survival probability of severely burned patients.

METHODS

This retrospective study presents data from the Center for Severely Burned Patients of the General Hospital in Vienna. We included 1193 patients for over 20 years. Regression models were used to describe the prognostic accuracy of the ABSI.

RESULTS

The ABSI can still be used as a prognostic factor for the probability of survival of severely burned patients. The odds of passing increases by a factor of 2.059 for each unit increase in the ABSI with an area under the curve value of 0.909. Over time, the likelihood of survival increased. The existence of chronic kidney disease negatively impacts the survival probability of severely burned patients.

CONCLUSION

The ABSI can still be used to provide accurate information about the chances of survival of severely burned patients; however, further exploration of the impact of chronic kidney disease on the survival probability and adding variables to the ABSI scale should be considered. The probability of survival has increased over the last 20 years.

The Role of Microsurgery in Burn Surgery

Acute burn reconstruction involves intricate strategies such as skin grafting and innovative technologies, addressing challenges in coverage and minimizing donor site morbidity. Despite being rarely used, flap reconstruction becomes necessary when critical structures are exposed, offering robust coverage and reducing complications. However, free flaps in acute burns face challenges, including a higher failure rate attributed to hyperinflammatory states and hypercoagulability. Surgical optimization strategies involve careful timing, patient preparation, and meticulous postoperative care. In delayed burn reconstruction, free flaps proved effective in functional and aesthetic restoration, with low flap loss rates and minimal contracture recurrence. Prefabricated and prelaminated flaps emerged as a solution for complex cases, ensuring the best functional and aesthetic possible outcomes in challenging facial burn reconstructions.

Epidemiological and clinical characteristics of burns in adults: a 6-year retrospective study in a major burn center in Suzhou, China

Background

Burns are a prevalent form of unintentional injury and a significant public health concern in developing countries. We aimed to investigate the epidemiological and clinical characteristics of adult burn patients at a major center in Eastern China.

Methods

This 6-year retrospective study analyzed patients with varying degrees of burns between January 2017 and December 2022 at the Suzhou Burns and Trauma Center. The study extracted demographic, clinical, and epidemiological data from electronic medical records for analysis.

Results

The study included 3,258 adult patients, of which 64.3% were male. The largest age group affected 30-59-year-old adults (63.04%). Scalds were the leading cause of burns (1,346, 41.31%), followed by flames (1,271, 39.01%). The majority of burn hospitalizations were those with moderate burns (1791, 54.97%). The morbidity rate was low at 0.68%, while mortality was strongly associated with age, etiology, and total body surface area. Patients with certain types of burns, such as explosions, hot crush injuries, and electric burns had more operations, longer lengths of hospital stay, and higher costs compared to those with scalds and flame injuries.

Conclusion

Different prevention strategies should be formulated according to different etiologies, ages, and genders.

Interventions for postburn pruritus

BACKGROUND

Postburn pruritus (itch) is a common and distressing symptom experienced on healing or healed burn or donor site wounds. Topical, systemic, and physical treatments are available to control postburn pruritus; however, it remains unclear how effective these are.

OBJECTIVES

To assess the effects of interventions for treating postburn pruritus in any care setting.

SEARCH METHODS

In September 2022, we searched the Cochrane Wounds Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL), Ovid MEDLINE (including In-Process & Other Non-Indexed Citations), Ovid Embase, and EBSCO CINAHL Plus. We also searched clinical trials registries and scanned references of relevant publications to identify eligible trials. There were no restrictions with respect to language, publication date, or study setting.

SELECTION CRITERIA

Randomised controlled trials (RCTs) that enrolled people with postburn pruritus to compare an intervention for postburn pruritus with any other intervention, placebo or sham intervention, or no intervention.

DATA COLLECTION AND ANALYSIS

We used the standard methodological procedures expected by Cochrane. We used GRADE to assess the certainty of the evidence.

MAIN RESULTS

We included 25 RCTs assessing 21 interventions with 1166 randomised participants. These 21 interventions can be grouped into six categories: neuromodulatory agents (such as doxepin, gabapentin, pregabalin, ondansetron), topical therapies (such as CQ-01 hydrogel, silicone gel, enalapril ointment, Provase moisturiser, beeswax and herbal oil cream), physical modalities (such as massage therapy, therapeutic touch, extracorporeal shock wave therapy, enhanced education about silicone gel sheeting), laser scar revision (pulsed dye laser, pulsed high-intensity laser, fractional CO2 laser), electrical stimulation (transcutaneous electrical nerve stimulation, transcranial direct current stimulation), and other therapies (cetirizine/cimetidine combination, lemon balm tea). Most RCTs were conducted at academic hospitals and were at a high risk of performance, attrition, and detection bias. While 24 out of 25 included studies reported change in burn-related pruritus, secondary outcomes such as cost-effectiveness, pain, patient perception, wound healing, and participant health-related quality of life were not reported or were reported incompletely. Neuromodulatory agents versus antihistamines or placebo There is low-certainty evidence that doxepin cream may reduce burn-related pruritus compared with oral antihistamine (mean difference (MD) -2.60 on a 0 to 10 visual analogue scale (VAS), 95% confidence interval (CI) -3.79 to -1.42; 2 studies, 49 participants). A change of 2 points represents a minimal clinically important difference (MCID). Due to very low-certainty evidence, it is uncertain whether doxepin cream impacts the incidence of somnolence as an adverse event compared to oral antihistamine (risk ratio (RR) 0.64, 95% CI 0.32 to 1.25; 1 study, 24 participants). No data were reported on pain in the included study. There is low-certainty evidence that gabapentin may reduce burn-related pruritus compared with cetirizine (MD -2.40 VAS, 95% CI -4.14 to -0.66; 1 study, 40 participants). A change of 2 points represents a MCID. There is low-certainty evidence that gabapentin reduces the incidence of somnolence compared to cetirizine (RR 0.02, 95% CI 0.00 to 0.38; 1 study, 40 participants). No data were reported on pain in the included study. There is low-certainty evidence that pregabalin may result in a reduction in burn-related pruritus intensity compared with cetirizine with pheniramine maleate (MD -0.80 VAS, 95% CI -1.24 to -0.36; 1 study, 40 participants). A change of 2 points represents a MCID. There is low-certainty evidence that pregabalin reduces the incidence of somnolence compared to cetirizine (RR 0.04, 95% CI 0.00 to 0.69; 1 study, 40 participants). No data were reported on pain in the included study. There is moderate-certainty evidence that ondansetron probably results in a reduction in burn-related pruritus intensity compared with diphenhydramine (MD -0.76 on a 0 to 10 numeric analogue scale (NAS), 95% CI -1.50 to -0.02; 1 study, 38 participants). A change of 2 points represents a MCID. No data were reported on pain and adverse events in the included study. Topical therapies versus relevant comparators There is moderate-certainty evidence that enalapril ointment probably decreases mean burn-related pruritus compared with placebo control (MD -0.70 on a 0 to 4 scoring table for itching, 95% CI -1.04 to -0.36; 1 study, 60 participants). No data were reported on pain and adverse events in the included study. Physical modalities versus relevant comparators Compared with standard care, there is low-certainty evidence that massage may reduce burn-related pruritus (standardised mean difference (SMD) -0.86, 95% CI -1.45 to -0.27; 2 studies, 166 participants) and pain (SMD -1.32, 95% CI -1.66 to -0.98). These SMDs equate to a 4.60-point reduction in pruritus and a 3.74-point reduction in pain on a 10-point VAS. A change of 2 VAS points in itch represents a MCID. No data were reported on adverse events in the included studies. There is low-certainty evidence that extracorporeal shock wave therapy (ESWT) may reduce burn-related pruritus compared with sham stimulation (SMD -1.20, 95% CI -1.65 to -0.75; 2 studies, 91 participants). This equates to a 5.93-point reduction in pruritus on a 22-point 12-item Pruritus Severity Scale. There is low-certainty evidence that ESWT may reduce pain compared with sham stimulation (MD 2.96 on a 0 to 25 pressure pain threshold (PPT), 95% CI 1.76 to 4.16; 1 study, 45 participants). No data were reported on adverse events in the included studies. Laser scar revision versus untreated or placebo controls There is moderate-certainty evidence that pulsed high-intensity laser probably results in a reduction in burn-related pruritus intensity compared with placebo laser (MD -0.51 on a 0 to 1 Itch Severity Scale (ISS), 95% CI -0.64 to -0.38; 1 study, 49 participants). There is moderate-certainty evidence that pulsed high-intensity laser probably reduces pain compared with placebo laser (MD -3.23 VAS, 95% CI -5.41 to -1.05; 1 study, 49 participants). No data were reported on adverse events in the included studies.

AUTHORS' CONCLUSIONS

There is moderate to low-certainty evidence on the effects of 21 interventions. Most studies were small and at a high risk of bias related to blinding and incomplete outcome data. Where there is moderate-certainty evidence, practitioners should consider the applicability of the evidence for their patients.

Distribution of Nosocomial Pathogens and Antimicrobial Resistance among Patients with Burn Injuries in China: A Comprehensive Research Synopsis and Meta-Analysis

INTRODUCTION

Over the past decade, numerous studies have described the types of pathogens and their antibiotic resistance patterns in patients with burn injuries in China; however, the findings have generally been inconsistent. We conducted a literature search and meta-analysis to summarize the infection spectra and antimicrobial resistance patterns in patients with burn injuries.

METHODS

We searched the PubMed, Embase, Web of Science, China National Knowledge Infrastructure, China Biomedical Literature, Wanfang, and Weipu databases for relevant articles published between January 2010 and December 2023. The DerSimonian-Laird random-effects model was used to estimate the proportions and 95% confidence intervals (CIs) of pathogens among Chinese patients with burn injuries. Meta-regression analyses were performed to explore differences in the proportions of pathogens among different subgroups and their resistance patterns. This study was registered with PROSPERO (CRD42024514386).

RESULTS

The database searches yielded 2017 records; after removing duplicates and conducting initial screening, 219 articles underwent full-text screening. Ultimately, 60 studies comprising a total of 62,819 isolated strains reported the proportions of pathogens in patients with burn injuries and were included in this meta-analysis. Meta-analyses were conducted on 18 types of pathogens. The most common pathogens causing infections in Chinese patients with burn injuries were Staphylococcus aureus, Pseudomonas aeruginosa, Acinetobacter baumannii, Klebsiella pneumoniae, and Staphylococcus epidermidis. Similar results were observed in the subgroup analysis focusing on wound infections. Since 2015, there has been a significant decrease in the proportion of Pseudomonas aeruginosa (R2 = 4.89%) and a significant increase in the proportion of Klebsiella pneumoniae (R2 = 9.60%). In terms of antibiotic resistance, there has been a significant decrease in the resistance of Staphylococcus aureus to multiple antibiotics and an increasing trend in the resistance of Klebsiella pneumoniae.

CONCLUSIONS

We systematically summarized the epidemiological characteristics and antibiotic resistance patterns of pathogens among individuals suffering from burns in China, thus providing guidance for controlling wound infections and promoting optimal empirical antimicrobial therapy. The observed high levels of antibiotic resistance underscore the need for ongoing monitoring of antibiotic usage trends.

Prognostic Scores for Mortality in Invasive Mechanically Ventilated Burn Patients

INTRODUCTION

Managing burn patients is a challenge requiring a multidisciplinary team with the ability to predict complications and act early to avoid them. There are few studies characterizing the population of critically ill burn patients in need of ventilatory support. This study aimed to describe the population of burn patients in need of invasive mechanical ventilation support and assess in-hospital mortality and the factors associated with it.

MATERIAL AND METHODS

A longitudinal retrospective study was conducted, including burn patients admitted to a tertiary hospital burn unit over five consecutive years, who required invasive mechanical ventilation support during their hospitalization. Demographic data, comorbidities, characteristics of the injury scene, etiology, and characteristics of the burn were collected. Length of mechanical ventilation and hospitalization as well as mortality rate were evaluated. The determination of mortality predictors and the prognostic performance of mortality prediction scores were analyzed. A one-year follow-up was performed to evaluate the survival of discharged patients.

RESULTS

A total of 141 patients were included in this study; 68.1% patients were male with a median age of 58 years. The mean percentage of total body surface area (TBSA) burned was 24.5%. Home incidents were the most frequent, and fire was the most common cause of burns (80.9% of patients). The mean Abbreviated Burn Severity Index Score (ABSI) was 7.83, with an area under the curve in receiver operating characteristic curve (ROC) analysis (AUC_ROC) of 0.725; the mean Belgium Outcome of Burn Injury (BOBI) score was 3.45, with AUC_ROC of 0.740 and mean R-Baux of 89.1 and AUC_ROC of 0.834. The mean duration of invasive mechanical ventilation was 16.9±19.3 days. Age (p<0.001), length of mechanical ventilation (p<0.001), length of hospitalization (p<0.001), higher degree of burn (p=0.001), TBSA (p=0.040), and the presence of buttock burn (0.006) were associated with mortality in this sample. In-hospital mortality was 29.8%. The survival group had a 12% death rate at one-year follow-up, mostly in the first three months after discharge.

CONCLUSION

Age, duration of mechanical ventilation, length of hospitalization, higher degree of burn, TBSA, and the presence of buttock burn were associated with mortality in this sample. R-Baux score was the most accurate test score to predict mortality in this challenging group of patients.

Why does a public health issue (not) get priority? Agenda setting for the national burns programme in India

There is growing scholarly interest in what leads to global or national prioritization of specific health issues. By retrospectively analysing agenda setting for India's national burn programme, this study aimed to better understand how the agenda-setting process influenced its design, implementation and performance. We conducted document reviews and key informant interviews with stakeholders and used a combination of analytical frameworks on policy prioritization and issue framing for analysis. The READ (readying material, extracting data, analysing data and distilling findings) approach was used for document reviews, and qualitative thematic analysis was used for coding and analysis of documents and interviews. The findings suggest three critical features of burns care policy prioritization in India: challenges of issue characteristics, divergent portrayal of ideas and its framing as a social and/or health issue and over-centralization of agenda setting. First, lack of credible indicators on the magnitude of the problem and evidence on interventions limited issue framing, advocacy and agenda setting. Second, the policy response to burns has two dimensions in India: response to gender-based intentional injuries and the healthcare response. While intentional burns have received policy attention, the healthcare response was limited until the national programme was initiated in 2010 and scaled up in 2014. Third, over-centralization of agenda setting (dominated by a few homogenous actors, located in the national capital, with attention focused on the national ministry of health) contributed to limitations in programme design and implementation. We note following elements to consider when analysing issues of significant burden but limited priority: the need to analyse how actors influence issue framing, the particularities of issues, the inadequacy of any one dominant frame and the limited intersection of frames. Based on this analysis in India, we recommend a decentralized approach to agenda setting and for the design and implementation of national programmes from the outset.

Exploring the Demographic and Social Correlates of Burn Injuries: A Comprehensive Study From a Regional Burn Center in Pakistan

Burn injuries pose significant challenges to both patients and healthcare systems globally. This retrospective observational study, conducted at the burn center in a tertiary care hospital in Rawalpindi, Pakistan, aimed to delineate the patterns of burn injuries and correlate them with demographic and clinical presentations. A total of 99 patients were included, with 54 males and 45 females, ranging in age from three months to 70 years. Flame burns were the most common type (n=69), with the majority being accidental (n=87). Limbs were the most frequently affected body parts (n=32), often with lesser-degree burns (n=28). Notably, self-inflicted injuries were predominantly observed in males (n=7), while assault cases were more common in females (n=4). Statistical analysis revealed significant associations between the degree of burn and the body parts affected, as well as between the mode of injury and the affected body parts. Burn injuries due to assault or self-infliction tended to have higher morbidity rates, often resulting in fatalities. Additionally, the cause of burn injury showed significant associations with the affected body parts, with contact and electric burns affecting limbs and chemical burns mainly affecting the head and face. These findings underscore the need for targeted burn prevention programs, emphasizing first aid education and addressing specific risk factors in high-risk groups and settings. By implementing preventive strategies and evaluating their effectiveness, the burden of burn injuries can be reduced, leading to improved patient outcomes and quality of life.

Associations between burn care services and impairment at discharge after burn injury: Analysis of the Global Burn Registry

BACKGROUND

Throughout the world, burn injury is a major cause of death and disability. In resource-limited countries, burn injury is one of the leading causes of permanent disability among children who survive traumatic injuries, and burn injury is the fourth leading cause of disability worldwide. This study applied Andersen's model of health care access to evaluate if patient characteristics (predisposing factors), burn care service availability (enabling factors) and injury characteristics (need) are associated with physical impairment at hospital discharge for patients surviving burn injuries globally. Specifically, access to rehabilitation, nutrition, operating theatre, specialized burn unit services, and critical care were investigated as enabling factors. The secondary aim was to determine whether associations between burn care service availability and impairment differed by country income level.

METHODS

This is a cross-sectional secondary analysis of prospectively collected data from the World Health Organization, Global Burn Registry. The outcome of interest was physical impairment at discharge. Simple and multivariable logistic regressions were used to test the unadjusted and adjusted associations between the availability of burn care services and impairment at hospital discharge, controlling for patient and injury characteristics. Effect modification was analyzed with service by country income level interaction terms added to the models and, if significant, the models were stratified by income.

RESULTS

The sample included 6622 patients from 20 countries, with 11.2% classified with physical impairment at discharge. In the fully adjusted model, patients had 89% lower odds impairment at discharge if the treatment facility provided reliable rehabilitation services compared to providing limited or no rehabilitation services (OR.11, 95%CI.08,.16, p < .01). However, this effect was modified by county income with the strong and significant association only present in high/upper middle-income countries. Sophisticated nutritional services were also significantly associated with less impairment in high/upper middle-income countries (OR=.04, 95% CI 0.203, 0.05, p < .01), but significantly more impairment in lower middle/low-income countries (OR=2.01, 95% CI 1.50, 2.69, p < .01). Patients had 444% greater odds of impairment if treated at a center with specialty burn unit services (OR 5.44, 95%CI 3.71, 7.99, p < .01), possibly due to a selection effect.

DISCUSSION

Access to reliable rehabilitation services and sophisticated nutritional services were strongly associated with less physical impairment at discharge, but only in resource-rich countries. Although these findings support the importance of rehabilitation and nutrition after burn injury, they also highlight potential disparities in the quantity or quality of services available to burn survivors in poorer countries.

Bacterial fluorescence imaging as a predictor of skin graft integration in burn wounds

BACKGROUND

Split-thickness skin graft (STSG)1 integration rates are susceptible to improvement. Infection and/or biofilm should be appropriately addressed prior to grafting to improve the likelihood of graft-take. Incorporating technological aids such as fluorescence (FL)2 imaging (MolecuLight®), which accurately locates areas of bacterial loads above 104 CFU/gr, for graft site assessment and preparation could yield better outcomes.

METHODS

This single-center, prospective observational study included adult burn patients with previously infected wounds that had been deemed clinically and microbiologically clean and were therefore candidates for grafting. Prior to grafting, a FL imaging assessment (blinded to the surgical team) localized areas positive for moderate-high bacterial loads (>104 CFU/gr). Intra-operatively, a standard swab sample from the recipient site was collected by the surgical team. Postoperatively, areas positive/negative for FL and areas of graft take and failure were overlapped and measured (cm2) over a 2D schematic. The performance and accuracy of FL imaging and swab sampling in relation to graft outcomes were assessed.

RESULTS

38 patients were enrolled in the study. The mean total body surface area (TBSA)3 involvement was 14.5 ± 12.4 % [range 0.8 - 40.2 %]. 25/38 of the subjects enrolled had complete graft take while 13 had partial graft losses. There were no total losses. FL-imaging was positive in 100 % of losses versus 31 % (4/13) of the swab microbiology. FL-imaging was found to have a sensitivity of 86 %, specificity of 98 %, PPV of 72 %, NPV of 99 %, and an accuracy of 94 % for predicting any type or range of graft loss in the entire cohort. Meanwhile, the sensitivity of microbiology from swab samples was 30 %, with a specificity of 76 %.

CONCLUSIONS

FL imaging is an accurate method for assessing recipient sites and predicting the outcome of a skin graft among burn patients. These findings suggest that FL imaging can inform better decision-making surrounding grafts that may lead to better outcomes.

A single-center, open-labeled, randomized, 6-month, parallel-group study to assess the safety and efficacy of allogeneic cultured keratinocyte sheet transplantation for deep second-degree burn wounds: rationale and design of phase I/II clinical trial

BACKGROUND

Burn-related injuries are a major global health issue, causing 180,000 deaths per year. Early debridement of necrotic tissue in association with a split-thickness skin graft is usually administered for some of the 2nd- and 3rd-degree injuries. However, this approach can be complicated by factors such as a lack of proper donor sites. Artificial skin substitutes have attracted much attention for burn-related injuries. Keratinocyte sheets are one of the skin substitutes that their safety and efficacy have been reported by previous studies.

METHODS

Two consecutive clinical trials were designed, one of them is phase I, a non-randomized, open-label trial with 5 patients, and phase II is a randomized and open-label trial with 35 patients. A total number of 40 patients diagnosed with 2nd-degree burn injury will receive allogenic keratinocyte sheet transplantation. The safety and efficacy of allogeneic skin graft with autograft skin transplantation and conventional treatments, including Vaseline dressing and topical antibiotic, will be compared in different wounds of a single patient in phase II. After the transplantation, patients will be followed up on days 3, 7, 10, 14, 21, and 28. In the 3rd and 6th months after the transplantation scar, a wound closure assessment will be conducted based on the Vancouver Scar Scale and the Patient and Observer Scar Assessment Scale.

DISCUSSION

This study will explain the design and rationale of a cellular-based skin substitute for the first time in Iran. In addition, this work proposes this product being registered as an off-the-shelf product for burn wound management in the country.

TRIAL REGISTRATION

Iranian Registry of Clinical Trials (IRCT) IRCT20080728001031N31, 2022-04-23 for phase I and IRCT20080728001031N36, 2024-03-15 for phase II.

Comparing the antibacterial and healing properties of medical-grade honey and silver-based wound care products in burns

Burns are a major global healthcare concern, often complicated by the presence of bacteria such as Pseudomonas aeruginosa in the wounds. Silver-based dressings are commonly used in the treatment of burns but can cause skin irritation and delay healing time. Medical-grade honey (MGH) provides an interesting alternative. This study investigated the antimicrobial effects and possible cytotoxicity of L-Mesitran Soft (MGH-gel) and its individual components, Medihoney (Manuka), Flammazine (silver sulphadiazine), and silver nitrate (AgNO3) in an ex vivo human burn wound model. Bacterial survival and wound healing parameters, including re-epithelialization and keratinocyte proliferation were assessed. L-Mesitran, Flammazine, and AgNO3 reduced P. aeruginosa numbers below detection levels. L-Mesitran Soft exhibited a significantly stronger antimicrobial effect compared to Medihoney. The individual components of L-Mesitran contributed significantly to its antibacterial efficacy, thus suggesting synergistic activities. Moreover, L-Mesitran, Flammazine, and AgNO3 slightly inhibited re-epithelialization while Medihoney treatment resulted in a complete lack of re-epithelialization and keratinocyte proliferation. Furthermore, clinical cases illustrated the effectiveness of MGH therapy in infected burns. Overall, L-Mesitran Soft had similar effects as silver-based products on bacterial load and epidermal regeneration, but outperformed Medihoney. Therefore, supplemented MGH could be used as an effective alternative to silver-based dressings for P. aeruginosa-infected burns.

Predictors of mortality following electrical and lightning injuries in Malawi: A decade of experience

INTRODUCTION

Electrical injuries can be devastating, and data is lacking in low-resource settings. We aimed to identify predictors of mortality following electrical and lightning injuries (ELI) in Malawi.

METHODS

We performed a retrospective observational study of patients presenting with ELI and burn injuries at a tertiary hospital in Malawi from 2011 to 2020. Outcomes were compared and predictors of mortality were modeled.

RESULTS

A total of 382 ELI and 6371 burn patients were included. The mean ages for ELI and burn groups were 24 ± 14 and 11 ± 14 years, respectively (p < 0.01). Most patients were injured at home (91% in the burn group versus 51% in the ELI group, p < 0.01). The crude mortality rate in the ELI group was 28%, compared to 12% in the burn group (p < 0.01). On multivariate logistic regression, predictors of mortality included ELI (odds ratio [OR] 13.3, 95% confidence interval [CI] 7.2-24.5) and total body surface area burned (OR 1.1, 95% CI 1.1-1.1). Predicted mortality for ELI has increased over time (p = 0.05).

CONCLUSIONS

ELI confers more than 13 times higher odds of mortality than burn injuries in Malawi, with mortality risk increasing over time. More efforts are needed to prevent electrical hazards and implement timely interventions for patients with ELI.

Health-related quality of life after burn injury due to bioethanol-fueled fireplaces

OBJECTIVE

Commercially available bioethanol-fueled fireplaces are a potential source of burns and are commonly used for home use. The present study aimed to evaluate the quality of life following burn injuries that were caused by bioethanol-related accidents.

METHODS

Burned patients who were admitted to our burn unit with burn injury due to bio-ethanol fueled fire places between January 2010 and December 2021 were contacted to ask for their willingness to participate in this study. They were asked to answer questions regarding the circumstances of the accident and three questionnaires to capture burn specific and general health related quality of life (Burn Specific Health Scale-Brief (BSHS-B), Short-Form Health Survey 36 (SF-36)) and general information about the accident. Patients were matched and compared to a group of patients suffering comparable burns from other burn mechanisms, which were also admitted to our burn unit at the same time.

RESULTS

Of 35 patients that met the inclusion criteria, 19 answered the questionnaire and were compared to 38 patients with other burn mechanisms. There were no statistical differences regarding age (bioethanol: 37.4 ± 14.7 years vs. control: 36.2 ± 14.3 years, p = 0.777), TBSA (9.9 ± 6.8% vs. 8.9 ± 10.4, p = 0.715), and sex (42.1% females vs. 36.8% females, p = 0.882). Most patients in the bioethanol-group reported that they did not follow the manual instructions (68.4%) and that the accident happened during the refilling process (52.6%). There was no significant difference in any subscale of the BSHS-B or the SF-36.

DISCUSSION

Burns related to bioethanol-fueled fireplaces are rare compared to other typical burn mechanisms. However, as they are used for personal pleasure and interior design, psychological impairment following burn may be even more critical. Detailed education on the use of these fireplaces needs to take place in order to reduce the risk of accidents.

Wound healing effect of nutmeg (Myristica fragrans) cream on second-degree burn in animal model

Second-degree burn, the most common among burn degrees, underscores the importance of timely and proper treatment in influencing prognosis. Nutmeg (Myristica fragrans), renowned for its potent antibacterial and antifungal properties, also serves as an effective antiseptic for open wounds. The aim of this study was to identify the phytochemical constituents of nutmeg essential oil and analyze the wound healing effect of nutmeg cream on second-degree burns in an animal model. An experimental study with a completed randomized design was conducted on Rattus norvegicus strain Wistar rats with second-degree burn. This study had four groups and each group consisting of four rats: B (burn-treated base cream), B+N (burn-treated 3% nutmeg cream), B+SSD (burn-treated silver sulfadiazine (BSS)), and B+N+SSD (burn-treated 3% nutmeg cream and SSD in a 1:1 ratio). The phytochemical analysis of nutmeg essential oil was conducted by gas chromatography and mass spectroscopy (GC-MS). The burn diameter and burn wound healing percentage were measured from day 0 to 18. One-way ANOVA followed by post hoc analysis using the least significant difference (LSD) was employed to analysis the effect. The phytochemical analysis of nutmeg essential oil found that myristicin, terpinene-4-ol, terpinene, safrole and terpinolene were the most abundant putative compounds in nutmeg essential oil. On day 0, the average burn wound diameters were 1.4 cm in all groups and increases were observed in all groups on day 3. The wound diameter decreased until day 18 with the smallest burn wound diameter was found in the B+N group (0.86±0.37 cm), followed by B+SSD (0.93±0.29 cm). The B+SSD group exhibited the highest percentage of burn wound healing (56.80±14.05%), which was significantly different from the base cream (p<0.05). The percentage of burn wound healing in rats given 3% nutmeg cream was 41.88±13.81%, suggesting that nutmeg cream could promote burn wound healing in rats induced by second-degree burns.

Coenzyme Q10 supplementation in burn patients: a double-blind placebo-controlled randomized clinical trial

BACKGROUND

Burn injuries are important medical problems that, aside from skin damage, cause a systemic response including inflammation, oxidative stress, endocrine disorders, immune response, and hypermetabolic and catabolic responses which affect all the organs in the body. The aim of this study was to determine the effect of coenzyme Q10 (CoQ10) supplementation on inflammation, oxidative stress, and clinical outcomes in burn patients.

METHODS

In a double-blind placebo-controlled randomized clinical trial, 60 burn patients were randomly assigned to receive 100 mg CoQ10 three times a day (total 300 mg/day) or a placebo for 10 days. Inflammatory markers including erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), oxidative stress markers including total antioxidant capacity (TAC), malondialdehyde (MDA) and superoxide dismutase (SOD) activity, fasting blood glucose (FBG), blood urea nitrogen (BUN), creatinine, white blood cells (WBC), and body temperature were assessed as primary outcomes and albumin, prothrombin time (PT), partial thromboplastin time (PTT), international normalized ratio (INR), other hematological parameters, blood pressure, O2 saturation, ICU duration, and 28-mortality rate were assessed as secondary outcomes.

RESULTS

Fifty-two participants completed the trial. CRP and ESR levels were not significantly different between CoQ10 and placebo groups at the end of the study (P = 0.550 and P = 0.306, respectively). No significant differences between groups were observed for TAC (P = 0.865), MDA (P = 0.692), and SOD activity (P = 0.633) as well. Administration of CoQ10 resulted in a significant increase in albumin levels compared to placebo (P = 0.031). There was no statistically significant difference between the two groups in other measured outcomes (P > 0.05).

CONCLUSION

Results showed that in patients with burn injury, CoQ10 administration had no effect on inflammatory markers and oxidative stress, although serum albumin levels were improved after supplementation. Further studies with albumin as the primary outcome are needed to confirm this finding.

Acute kidney injury in patients with burns

Burn injury is associated with a high risk of acute kidney injury (AKI) with a prevalence of AKI among patients with burns of 9-50%. Despite an improvement in burn injury survival in the past decade, AKI in patients with burns is associated with an extremely poor short-term and long-term prognosis, with a mortality of >80% among those with severe AKI. Factors that contribute to the development of AKI in patients with burns include haemodynamic alterations, burn-induced systemic inflammation and apoptosis, haemolysis, rhabdomyolysis, smoke inhalation injury, drug nephrotoxicity and sepsis. Early and late AKI after burn injury differ in their aetiologies and outcomes. Sepsis is the main driver of late AKI in patients with burns and late AKI has been associated with higher mortality than early AKI. Prevention of early AKI involves correction of hypovolaemia and avoidance of nephrotoxic drugs (for example, hydroxocobalamin), whereas prevention of late AKI involves prevention and early recognition of sepsis as well as avoidance of nephrotoxins. Treatment of AKI in patients with burns remains supportive, including prevention of fluid overload, treatment of electrolyte disturbance and use of kidney replacement therapy when indicated.

What are the triggers for palliative care referral in burn intensive care units? Results from a qualitative study based on healthcare professionals' views, clinical experiences and practices

BACKGROUND

Burns are a global public health problem, accounting for around 300,000 deaths annually. Burns have significant consequences for patients, families, healthcare teams and systems. Evidence suggests that the integration of palliative care in burn intensive care units improves patients' comfort, decision-making processes and family care. Research is needed on how to optimise palliative care referrals.

AIM

To identify triggers for palliative care referral in critically burned patients based on professionals' views, experiences and practices.

DESIGN

Qualitative study using in-depth interviews.

SETTING/PARTICIPANTS

All five Burn Intensive Care Units reference centres across Portugal were invited; three participated. Inclusion criteria: Professionals with experience/working in these settings. A total of 15 professionals (12 nurses and 3 physicians) participated. Reflexive thematic analysis was performed.

RESULTS

Three main triggers for palliative care referral were identified: (i) Burn severity and extension, (ii) Co-morbidities and (iii) Multiorgan failure. Other triggers were also generated: (i) Rehabilitative palliative care related to patients' suffering and changes in body image, (ii) Family suffering and/or dysfunctional and complex family processes, (iii) Long stay in the burn intensive care unit and (iv) Uncontrolled pain.

CONCLUSIONS

This study identifies triggers for palliative care in burn intensive care units based on professionals' views, clinical experiences and practices. The systematisation and use of triggers could help streamline referral pathways and strengthen the integration of palliative care in burn intensive care units. Research is needed on the use of these triggers in clinical practice to enhance decision-making processes, early and high-quality integrated palliative care and proportionate patient and family centred care.

The healing effect of a mixture of Arnebia euchroma and animal fat on burn wounds in rats in comparison with sulfadiazine

OBJECTIVE

Thermal burn is a serious cause of morbidity and mortality that affects millions of people worldwide. The aim of this experimental study was to investigate the efficacy of Arnebia euchroma (AE) to treat burn wounds in a rat model.

METHOD

A total of 80 male rats (200-250g) were shaved over the back of the neck (2×3cm2) and a second-degree burn wound was induced at this site under general anaesthesia. The rats were then randomly assigned to one of four groups (each n=20) and the burns were treated daily for 14 days as follows: (1) dressed with animal fat; (2) dressed with sulfadiazine; (3) dressed with a mixture of AE and animal fat; (4) no treatment (control). Five rats from each group were sacrificed on days 3, 5, 9 and 14 post-burn and the wounds were evaluated histologically and immunohistochemically for the expression of interleukin (IL)-1 and IL-6.

RESULTS

There was a significant increase at day 3 and decrease on day 5 samples for the expression of IL-1 in the AE plus fat group and IL-6 in the AE plus fat and sulfadiazine groups, compared to the control and fat treatment groups, respectively. Both AE plus fat and sulfadiazine treatments reduced inflammation and granulation tissue formation by day 5 post-burn, while re-epithelialisation commenced by day 9 post-burn. In addition, burns treated with AE plus fat exhibited keratinised epidermis, associated with regular collagen fibres, compared to moderately dense collagen fibres without vascularisation in the sulfadiazine group.

CONCLUSION

These findings suggested that AE plus fat was superior to sulfadiazine in enhancing burn wound healing in rats.

The effectiveness of the psychosocial empowerment program in early adjustment among adult burn survivors

BACKGROUND

Burns constitute a major global health challenge, causing not only physical trauma, but also significant psychosocial and emotional disturbances. The complexity of these injuries requires comprehensive rehabilitation programs that address both the physical and psychosocial aspects of recovery. Despite advances in medical care, there is a lack of standardized, accessible, and sustainable psychosocial interventions for burn survivors, particularly in the transition from hospital to home. This study aimed to develop and evaluate a nurse-led psychosocial empowerment intervention for early adjustment among burn survivors after hospital discharge.

METHODS

The study adopted a quasi-experimental framework. A convenient sample of 80 adult burn survivors was randomly divided into an intervention group, receiving the psychosocial empowerment program, and a control group, continuing standard care from November 2022 to May 2023. The effectiveness of the program was evaluated using various tools that measure satisfaction with appearance, coping abilities, and symptoms of post-traumatic stress disorder (PTSD). The intervention focused on enhancing resilience, self-efficacy, and adaptive coping, through targeted skill building in stress management, adaptability to coping, social reintegration, emotion regulation, and problem-solving.

RESULTS

Participants in the intervention group demonstrated significant improvements in body image satisfaction, coping abilities, and symptoms of PTSD compared to the control group.

CONCLUSIONS

The psychosocial empowerment program effectively addressed the psychosocial needs of burn survivors and enhanced their early adjustment after hospital discharge. The findings highlight the critical role of psychosocial support in the rehabilitation of burn survivors and underscore the need to integrate such interventions into standard post-discharge care. Future research should focus on the long-term effects of these interventions and their applicability in diverse settings.

Clinical efficacy of rhGM-CSF gel and medical collagen sponge on deep second-degree burns of infants: A randomized clinical trial

BACKGROUND

This study aimed to observe clinical efficacy of recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF) gel, medical collagen sponge and rhGM-CSF gel in combination with medical collagen sponge on deep second-degree burns of head, face or neck in infants.

METHODS

A total of 108 infants with deep second-degree burns on head, face or neck were randomly divided into rhGM-CSF group, medical collagen sponge group, and rhGM-CSF + medical collagen sponge group. The scab dissolving time, healing time, bacterial positive rate and Vancouver scar scale were evaluated and analyzed.

RESULTS

The data analysis showed that scab dissolving time and healing time were shorter in rhGM-CSF + medical collagen sponge group than that in rhGM-CSF group and medical collagen sponge group, and the difference was statistically significant (P < .05). Bacterial positive rate was lower in rhGM-CSF + medical collagen sponge group than that in rhGM-CSF group and medical collagen sponge group (P < .05). After 3 months, score of Vancouver scar scale (scar thickness, pliability, pigmentation and vascularity) was less in rhGM-CSF + medical collagen sponge group than that in rhGM-CSF group and medical collagen sponge group (P < .05).

CONCLUSION

rhGM-CSF gel in combination with medical collagen sponge is significantly effective in treating deep second-degree burns of head, face or neck in infants. This combination is beneficial for infection control, acceleration of scab dissolving and wound healing, and reduction of scar hyperplasia and pigmentation, which is worthy of clinical application and promotion.

Use of autologous adipose tissue in acute burn wound management: A systematic review

Fat transfer is increasingly used as part of our reconstructive armamentarium to address the challenges encountered in burn wounds and reconstructive surgery. The present systematic review aimed to evaluate the effectiveness of autologous fat transfer for acute burn wound management. A systematic review of the US National Library of Medicine, Cochrane Library, Web of Science, and Embase was conducted on October 15, 2022 (registration number CDR42022369726). A database watch was performed until submission of the manuscript. The review focused on wound healing. All studies reporting fat transfer in adult patients (at least 5 patients reported) with deep 2nd degree burn wounds were included. The database search yielded a total of 720 records and 367 patients were included from 3 studies. A statistically significant improvement in scar texture, scar appearance, and time to healing was reported in one study in the fat transfer group versus control (P<0.001). Similarly, scores for scar color, scar thickness, scar stiffness, and scar regularity increased significantly. The small number of included studies and their heterogeneity did not allow a meta-regression to be performed. This systematic review emphasizes the limited evidence currently available regarding the use of autologous fat transfer to improve burn wound healing in adult patients, even though it seems promising. Future search should focus on randomized controlled trials with a larger number of participants.

Acute care for burn patients: fluids, surgery, and what else?

PURPOSE OF REVIEW

Recently published initiatives spanning the burn care spectrum have substantially changed the standard of care in burn care. The purpose of this article is to describe new impactful concepts in burn first aid, triage, resuscitation, and treatment as well as their impact on future research.

RECENT FINDINGS

First aid after burn injury traditionally consists of extinguishing the burn and applying dressings. Recent evidence suggests that applying 20 min of cool tap water to the burn wound in the first 3 h postburn mitigates burn injury extent. National burn center transfer criteria have been updated, impacting patient initial transfer and management. The adverse effects of hydroxocobalamin, a commonly used antidote for cyanide toxicity, have been delineated. Initial burn resuscitation recommendations for both volume and potentially fluid type are being reexamined. The emergence of innovative skin substitutes may improve burn survival by providing a physiologically stabilizing intermediate dressing. Finally, formal clinical practice guidelines for early mobility in the ICU after burn injury have been defined.

SUMMARY

These changes in burn care, triage, resuscitation, and treatment have challenged traditional burn care standards, created new standards, and are the basis for future prospective randomized trials.

An Overview of Recent Developments in the Management of Burn Injuries

According to the World Health Organization (WHO), around 11 million people suffer from burns every year, and 180,000 die from them. A burn is a condition in which heat, chemical substances, an electrical current or other factors cause tissue damage. Burns mainly affect the skin, but can also affect deeper tissues such as bones or muscles. When burned, the skin loses its main functions, such as protection from the external environment, pathogens, evaporation and heat loss. Depending on the stage of the burn, the patient's condition and the cause of the burn, we need to choose the most appropriate treatment. Personalization and multidisciplinary collaboration are key to the successful management of burn patients. In this comprehensive review, we have collected and discussed the available treatment options, focusing on recent advances in topical treatments, wound cleansing, dressings, skin grafting, nutrition, pain and scar tissue management.

Neutrophil Count in Severe Burns Is Useful for Predicting Prognosis

Background

Burn injuries, particularly extensive severe burns, often have a fatal prognosis. However, many prognostic predictors are based on changes in the clinical course of treatment, and no prognostic predictors can be estimated in the early phases of injury. Using the Burn Index (BI) for evaluations requires familiarity with daily burn treatment, such as being able to evaluate the change from a second degree burn to a third degree burn appropriately. We sought to find a simpler and more quantitative prognostic prediction index.

Methods We hypothesized that, in addition to the current prognostic predictors, the number of neutrophils in severe burns may correlate with the prognosis, and analyzed its usefulness. The neutrophil and white blood cell counts were measured within 48 hours of injury in 35 burn patients who required inpatient treatment at our own institution. Mann-Whitney test was used to determine the significant of differences between the Survivor and Non-survivor groups.

Results

Compared to the Survivor group, neutrophil (P = 0.038) and white blood cell counts were increased significantly in the Non-survivor group (P = 0.004). Neutrophil counts and white blood cell counts correlated positively with the length of hospital stay, total body surface area, Prognostic Burn Index (PBI), and BI. The BI and PBI correlated with patient prognosis, as did neutrophil and white blood cell counts.

Conclusion

These results suggested that neutrophil and white blood cell counts in the early phases of burn injuries might be another factor in the prognosis of burn patients in addition to the current predictors.

Severe Burns of the Genital Area After Laser Hair Removal: A Case Report

Burn injuries are among the most commonly observed complications of laser hair removal. Here, we present a case, in which severe massive burns were caused in the genital and perineal areas during such a procedure. The consequent scar formation led not only to negative aesthetic effects but also affected the physical and psychological health of the patient.

Health systems research in burn care: an evidence gap map

BACKGROUND

Burn injury is associated with significant mortality and disability. Resilient and responsive health systems are needed for optimal response and care for people who sustain burn injuries. However, the extent of health systems research (HSR) in burn care is unknown. This review aimed to systematically map the global HSR related to burn care.

METHODS

An evidence gap map (EGM) was developed based on the World Health Organization health systems framework. All major medical, health and injury databases were searched. A standard method was used to develop the EGM.

RESULTS

A total of 6586 articles were screened, and the full text of 206 articles was reviewed, of which 106 met the inclusion criteria. Most included studies were cross-sectional (61%) and were conducted in hospitals (71%) with patients (48%) or healthcare providers (29%) as participants. Most studies were conducted in high-income countries, while only 13% were conducted in low-and middle-income countries, accounting for 60% of burns mortality burden globally. The most common health systems areas of focus were service delivery (53%), health workforce (33%) and technology (19%). Studies on health policy, governance and leadership were absent, and there were only 14 qualitative studies.

CONCLUSIONS

Major evidence gaps exist for an integrated health systems response to burns care. There is an inequity between the burden of burn injuries and HSR. Strengthening research capacity will facilitate evidence-informed health systems and policy reforms to sustainably improve access to affordable, equitable and optimal burn care and outcomes.

Free Flap Failure and Complications in Acute Burns: A Systematic Review and Meta-analysis

Background

Severe acute burn injuries represent a challenge to the reconstructive surgeon. Free flap reconstruction might be required in cases of significant critical structure exposure and soft tissue deficits, when local options are unavailable. This study aimed to determine the free flap complication rate in acute burn patients.

Methods

A systematic review and meta-analysis were conducted and reported according to Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines and registered on the International Prospective Register of Systematic Reviews database (CRD42023404478). The following databases were accessed: Embase, PubMed, Web of Science, and Cochrane Library. The primary outcome was the free flap failure rate.

Results

The study identified 31 articles for inclusion. A total of 427 patients (83.3% men, 16.7% women) accounting for 454 free flaps were included. The mean patient age was 36.21 [95% confidence interval (CI), 31.25-41.16]. Total free flap loss rate was 9.91% [95% CI, 7.48%-13.02%], and partial flap loss was 4.76% [95% CI, 2.66%-8.39%]. The rate of venous thrombosis was 6.41% [95% CI, 3.90%-10.36%] and arterial thrombosis was 5.08% [95% CI, 3.09%-8.26%]. Acute return to the operating room occurred in 20.63% [16.33%-25.71%] of cases. Stratified by body region, free flaps in the lower extremity had a failure rate of 8.33% [95% CI, 4.39%-15.24%], whereas in the upper extremity, the failure rate was 6.74% [95% CI, 3.95%-11.25%].

Conclusion

This study highlights the high risk of free flap complications and failure in acute burn patients.

Anacaulase-bcdb for the treatment of severe thermal burns

INTRODUCTION

Accurate burn depth assessment and early excision of burn eschar with maximal dermal preservation are key concepts in the optimal care of burn injury. Although excision with knife has long since been standard of care, a newer technique for wound bed preparation utilizing a bromelain-based enzyme has gained popularity worldwide and may offer several advantages.

AREAS COVERED

Here we report the pharmacologic properties, evidence for clinical efficacy, safety, and tolerability of anacaulase-bcdb for the treatment of deep partial thickness and full thickness burns.

EXPERT OPINION

Anacaulase-bcdb is a safe, non-surgical, selective eschar removal agent. It offers advantages over surgical excision of burn with knife and fulfills two unmet needs: burn depth assessment and dermal preservation during excision. Evidence supports a faster time to complete eschar removal; reduced number of operations; reduction in the amount of autografting, length of stay, and blood loss; prevention of burn induced compartment syndrome; and improved cosmetic outcome.

Use of extracorporeal membrane oxygenation in children with burn injury: Case report and literature review

RATIONALE

Burns are one of the most debilitating injuries in the world and one of the major causes of accidental disability and death among children. Severe burns can result in irreversible brain damage, placing patients at high risk of brain failure and high mortality. Therefore, timely diagnosis and treatment of burn encephalopathy are crucial for improving prognosis. In recent years, extracorporeal membrane oxygenation (ECMO) has been increasingly used to improve the prognosis of patients with burns. Here, we report a case of ECMO treatment in a child with burns and review the relevant literature.

PATIENT CONCERNS

A 7-year-old boy with a modified Baux score of 24 presented with asphyxia, loss of consciousness, refractory hypoxemia, and malignant arrhythmia after smoke inhalation for 1 day. Fiberoptic bronchoscopy revealed a large amount of black carbon-like substances aspirated from the trachea.

DIAGNOSES

Considering that the boy inhaled a large amount of smoke, the clinical manifestation was unclear consciousness, laboratory examination revealed continuous low blood oxygen saturation, and bronchoscopy revealed a large amount of black carbon-like substances in the trachea, thereby leading to the diagnosis of asphyxia, inhalation pneumonia, burn encephalopathy, multiple organ dysfunction syndrome, and malignant arrhythmia. In addition, pulmonary edema and carbon monoxide poisoning are caused by chemical agents, gas fumes, and vapors.

INTERVENTIONS

The boy's blood oxygen saturation and blood circulation remained unstable despite various ventilation methods and medications, thus we decided to use ECMO. After 8 days of ECMO support, the patient was successfully weaned from the machine.

OUTCOMES

Under the application of ECMO, the respiratory and circulatory systems significantly improved. Nevertheless, due to the progressive brain injury caused by burns and the poor prognosis, the parents ceased all treatment and the boy passed away.

LESSONS

This case report demonstrates that brain edema and herniation can arise as phenotypes of burn encephalopathy, which is a challenge to treat in children. Children with confirmed or suspected burn encephalopathy should undergo diagnostic tests completed as soon as possible to confirm the diagnosis. After receiving ECMO treatment, the respiratory and circulatory systems of the burn victims reported significantly improved. Hence, ECMO is a viable alternative for supporting patients with burns.

Copper nano-architecture topical cream for the accelerated recovery of burnt skin

Skin burns are debilitating injuries with significant morbidity and mortality associated with infections and sepsis, particularly in immunocompromised patients. In this context, nanotechnology can provide pioneering approaches for the topical treatment of burnt skin. Herein, the significant recovery of radiation-damaged skin by exploiting copper ultrasmall-in-nano architectures (CuNAs) dispersed in a home-made cosmetic cream is described and compared to other noble metals (such as gold). Owing to their peculiar design and components, CuNAs elicit a substantial recovery from burned skin in in vivo models after one topical application, and a significant anti-inflammatory effect is highlighted by reducing cytokine expression. The treatment exhibited neither significant toxicity nor the alteration of copper metabolism in the target organs because of the CuNA biocompatibility. This study may open new horizons in the treatment of radiation dermatitis and skin burns caused by other external events.

The Potential of Medicinal Plants and Natural Products in the Treatment of Burns and Sunburn-A Review

Treating burns remains a challenge for modern medicine, especially in developing countries that cannot afford expensive, advanced therapies. This review article summarises clinical and animal model studies of botanical preparations and their mixtures in treating burn wounds and sunburn. Articles available in electronic databases such as PubMed, Scopus, Web of Science, Science Direct and Google Scholar, published in English in 2010-2022, were considered. In the described clinical trials, it was shown that some herbal preparations have better effectiveness in treating burn wounds, including shortening the healing time and reducing inflammation, than the conventional treatment used hitherto. These herbal preparations contained extracts from Albizia julibrissin, Alkanna tinctoria, Aloe vera, Arnebia euchroma, Betula pendula and Betula pubescens, Centella asiatica, Hippophaë rhamnoides, Juglans regia, Lawsonia inermis, and mixtures of Matricaria chamomilla and Rosa canina. Research on animal models shows that many extracts may potentially benefit the treatment of burn wounds and sunburn. Due to the diverse mechanism of action, antibacterial activity, the safety of use and cost-effectiveness, herbal preparations can compete with conventional treatment. The growing interest in alternative medicine and herbal medicine encourages further research. Not only single preparations but also their mixtures should be taken into account because the research conducted so far often suggests a synergistic effect of the ingredients.

Burns: Classification, Pathophysiology, and Treatment: A Review

Burns and their treatment are a significant medical problem. The loss of the physical barrier function of the skin opens the door to microbial invasion and can lead to infection. The repair process of the damage caused by the burn is impaired due to the enhanced loss of fluids and minerals through the burn wound, the onset of hypermetabolism with the concomitant disruption of nutrient supply, and derangements in the endocrine system. In addition, the initiated inflammatory and free radical processes drive the progression of oxidative stress, the inhibition of which largely depends on an adequate supply of antioxidants and minerals. Clinical experience and research provide more and more data to make the treatment of patients with thermal injury increasingly effective. The publication discusses disorders occurring in patients after thermal injury and the methods used at various stages of treatment.

Amphiphilic Chitosan Porous Membranes as Potential Therapeutic Systems with Analgesic Effect for Burn Care

Eliminating or at least lessening the pain is a crucial aspect of burns management, as pain can negatively affect mental health and quality of life, and it can also induce a delay on wound healing. In this context, new amphiphilic chitosan 3D porous membranes were developed and investigated as burns therapeutic systems with analgesic effect for delivery of lidocaine as local anesthetic. The highly porous morphology of the membranes and the structural modifications were evidenced by scanning electron microscopy (SEM), energy dispersive X-ray (EDX) analysis and infrared spectroscopy (FTIR). Improved compression mechanical properties, long-term hydrolytic degradation (28 days) evaluation and high swelling capacities (ranging from 8 to 22.6 g/g) indicate an increased capacity of the prepared membranes to absorb physiological fluids (burns exudate). Lidocaine in vitro release efficiency was favored by the decreased content of cross-linking agent (reaching maximum value of 95.24%) and the kinetic data modeling, indicating that lidocaine release occurs by quasi-Fickian diffusion. In addition to the in vitro evaluation of analgesic effect, lidocaine-loaded chitosan membranes were successfully investigated and proved antibacterial activity against most common pathogens in burns infections: Staphylococcus aureus and Methicillin-resistant Staphylococcus aureus.

Research progress on risk factors of delirium in burn patients: A narrative review

Delirium, an acute brain dysfunction, is a common and serious complication in burn patients. The occurrence of delirium increases the difficulty of patient treatment, is associated with various adverse outcomes, and increases the burden on the patient's family. Many scholars have studied the factors that cause delirium, but the causes, pathogenesis, and treatment of delirium in burn patients have not been fully revealed. There is no effective pharmacological treatment for delirium, but active preventive measures can effectively reduce the incidence of delirium in burn patients. Therefore, it is necessary to study the relevant factors affecting the occurrence of delirium in burn patients. This study was conducted on December 20, 2021 by searching the PubMed database for a narrative review of published studies. The search strategy included keywords related to "burns," "delirium," and "risk factors." We reviewed the characteristics of delirium occurrence in burn patients and various delirium assessment tools, and summarized the risk factors for the development of delirium in burn patients in terms of personal, clinical, and environmental factors, and we found that although many risk factors act on the development of delirium in burn patients, some of them, such as clinical and environmental factors, are modifiable, suggesting that we can estimate the exposure of burn patients to risk factors by assessing their likelihood of delirium occurring and to make targeted interventions that provide a theoretical basis for the prevention and treatment of burn delirium.
