Abstract Introduction As the population ages; burn centers, especially those with a large rural catchment, will be expected to care for older adults with complex medical co-morbidities. Recent work has shown that %TBSA at which 50% of patients would be expected to die (LD50) for elderly patients is up to 20% lower than non-elderly patients. However, the factors contributing to mortality are unclear. We undertook this study to characterize our experience with elderly burn patients in our rural state and to understand how mortality is affected by comorbid disease. Methods We performed a retrospective review of all burn patients ≥50 years old admitted to our burn center over a 5 year period between January 2014 and December 2018. We collected demographic and injury data including %TBSA, mechanism, inhalation injury status, discharge disposition, length of stay as well as complications including pneumonia, kidney injury, wound infection and graft loss. We calculated the modified Baux score, Charlson Comorbidity Index (CCI) and overall mortality for each patient. The %TBSA and CCI were correlated with complications and mortality using the Pearson correlation coefficient analysis. Results There were 243 patients (35%) who met inclusion criteria out of total of 688 burn admissions during that period. The median age was 60 years (mean 62.2, range: 50–95) and 72.4% were male. The median TBSA was 4% (mean: 8.2%, range: 0.5% - 55%). We found weak correlations between CCI and both pneumonia (R=0.177, p=0.005) and mortality (R=0.1297, p=0.0434). There was also a weak correlation between %TBSA and pneumonia (R=0.3302, p < 0.001), kidney injury (R=0.205, p=0.001), wound infection (R=0.1295, p=0.045) and graft loss (R=0.2616, p< 0.001). Interestingly, in the subgroup with > 15% TBSA burns (n=35), there was no significant correlation with increased complications. For the entire cohort, the predicted mortality based on the mean modified Baux score was 16%. The actual observed mortality was 4.1%. Conclusions Our findings suggest that, in our center, CCI is not predictive of burn related complications or mortality and %TBSA is not predictive of complications or death. The observed to expected mortality ratio was remarkably low. Applicability of Research to Practice As we treat older burn patients, it is important to identify the individual patient factors and hospital specific burn care factors that may improve outcomes in the elderly population.

Abstract Background In modern-day burn care, advanced age remains an important predictor for mortality among burn victims. In this study, we compared the complete treatment trajectory (including pre-hospital and surgical treatment) and the outcomes between an elderly burn population and a younger adult burn population. Methods In this nationwide study, data from the Dutch Burn Repository were used. This is a uniform national registration for Dutch specialized burn care. All adult patients that were admitted to one of the three Dutch burn centres from the period 2009 to 2015 were included in the analysis. Burn patients were considered as elderly when ≥65 years of age, and were then further subdivided into three age categories: 65–74, 75–85 and 85+ years. Younger adults in the age category 18–64 years were used as the reference group. Surgical management was studied comprehensively and included timing of surgery, the number of procedures and details on the surgical technique, especially the technique used for debridement and the grafting technique that was applied. For the comparison of clinical outcome, the following parameters were included: mortality, wound infections, length of stay/TBSA (total body surface area) burned, discharge disposition and secondary reconstructions. Results During the study period, 3155 adult patients were included (elderly, n = 505). Burn severity, reflected by the median TBSA, varied between 3.2–4.0% and was comparable, but aetiology and pre-hospital care were different between elderly and the younger adult reference group. Surgical treatment was initiated significantly faster in elderly burn patients (p < 0.001). Less selective techniques for surgical debridement were used in the elderly burns patients (hydrosurgery, 42.0% vs 23.5–22.6%), and on the other hand more avulsion (5.3% vs 7.3–17.6%) and primary wound closure (6.7% vs 24.5%). The most frequently used grafting technique was meshed skin grafts (79.2–88.6%); this was not related to age. Mortality increased rapidly with a higher age and showed a high peak in the 85+ category (23.8%). Furthermore, considerable differences were found in hospital discharge disposition between the elderly and the reference group. Conclusions In conclusion, elderly burn patients who require specialized burn care are vulnerable and medically challenging. Differences in aetiology, comorbidity, physiology and the management prior to admission possibly affect the initial surgical management and result in significantly worse outcomes in elderly. Elderly patients need optimal, timely and specialized burn care to enhance survival after burn injuries.

Common Cause

Introduction: In the elderly, impairment of kidney function occurs. Renal diseases overlap with anatomic and functional changes related to age-related involutionary processes. Mortality among patients with acute renal injury is approximately 50%, despite advances in treatment and diagnosis of AKI. The aim: To assess the incidence of acute kidney injury in elderly patients and to analyze the causes of acute renal failure depending on age. Materials and methods: A retrospective analysis included medical documentation of patients hospitalized in the Nephrology Clinic during the 6-month period. During this period 452 patients were hospitalized in the clinic. A group of 77 patients with acute renal failure as a reason for hospitalization was included in the study. Results: The prerenal form was the most common cause of AKI in both age groups. In both age groups, the most common cause was dehydration; in the group of patients up to 65 years of age, dehydration was 29.17%; in the group of people over 65 years - 43.39%. Renal replacement therapy in patients with AKI was used in 14.29% of patients. In the group of patients up to 65 years of age hemodialysis was 16.67% and above 65 years of age. -13.21% of patients. The average creatinine level in the group of younger patients at admission was 5.16 ± 3.71 mg / dl, in the group of older patients 3.14 ± 1.63 mg / dl. The size of glomerular filtration GFR in the group of younger patients at admission was 21.14 ± 19.54 ml / min, in the group of older patients 23.34 ± 13.33 ml / min. Conclusions: The main cause of acute kidney injury regardless of the age group was dehydration. Due to the high percentage of AKI in the elderly, this group requires more preventive action, not only in the hospital but also at home.

Background Acute kidney injury (AKI) is one of the most severe complications of burn injury. AKI with severe burn injury causes high mortality. This study aims to investigate the incidence of and predisposing factors for AKI in burn patients. Methods This is a single-center, retrospective, descriptive criterion standard study conducted from June 27, 2015, to March 8, 2016. We used Kidney Disease Improving Global Outcomes criteria to define and select patients with AKI. The study was conducted by recruiting in hospital patients who suffered from the flammable cornstarch-based powder explosion and were treated under primary care procedures. A total of 49 patients who suffered from flammable dust explosion-related burn injury were enrolled and admitted on June 27, 2015. The patients with more than 20% total body surface area of burn were transferred to the intensive care unit. Patients received fluid resuscitation in the first 24 hours based on the Parkland formula. The primary measurements were the incidence of and predisposing factors for AKI in these patients. Demographic characteristics, laboratory data, and inpatient outcomes were also evaluated. The incidence of AKI in this cohort was 61.2% (n = 30). The mortality rate was 2.0% (n = 1) during a 59-day follow-up period. The multivariate analysis revealed inhalation injury (adjusted OR = 22.0; 95% CI [1.4–358.2]) and meeting ≥3 American Burn Association (ABA) sepsis criteria (adjusted OR = 13.7; 95% CI [1.7–110.5]) as independent risk factors for early advanced AKI. Conclusions The incidence rate of AKI was higher in this cohort than in previous studies, possibly due to the flammable dust explosion-related burn injury. However, the mortality was lower than that expected. In clinical practice, indicators of inflammation, including ABA sepsis criteria may help in predicting the risk of AKI in patients with burn injury.

Outcomes of burn patients have significantly improved over the last two decades. A recent study in The Lancet showed that a burn size of over 60% total body surface area (TBSA) burned is now recognized as being associated with high risks; a decade ago similar risks resulted from a 40% TBSA burned. Similar data have been obtained in severely-burned adults and the elderly. This chapter discusses current standards, recent evidence, and future developments in burn care to improve outcomes of these patients. Critical components in the management of patients with burns are early adequate resuscitation, recognition and management of airway burns and appropriate treatment of the different stages of burn care—prehospital, early, and late management.

Tubular Atrophy

Despite available prevention and treatment measures, such as hydration, diuresis, magnesium supplementation, and amifostine, renal toxicity is still one of the major dose-limiting side effects of cisplatin. The aim of this review is to discuss the issue of cisplatin-induced nephrotoxicity in the elderly. Compared with young patients, the incidences of cisplatin-induced nephrotoxicity and acute kidney injury (AKI) in elderly patients are significantly increased, and survival time may be decreased. Following cisplatin treatment of elderly patients, tubulointerstitial injuries will be significantly aggravated based on their original age, both for acute injuries due to cell necrosis and exfoliation and chronic injuries due to interstitial fibrosis, tubular atrophy, and dilatation. The high incidence of cisplatin-induced nephrotoxicity in elderly patients may be associated with renal hypoperfusion; increased comorbidities, such as chronic kidney disease (CKD), cardiovascular disease, and diabetes mellitus; increased use of combined drugs [especially non-steroidal anti-inflammatory drugs, angiotensin-converting enzyme inhibitor and angiotensin receptor blockers (ACEI/ARB), and antibiotics]; decreased clearance of cisplatin; and high plasma ultrafilterable cisplatin. Considering hemodynamic stability and water balance, short duration and low volume hydration may be more suitable for treating elderly people. With the increasing popularity of low-dose daily/weekly regimens, we do not recommend routine diuretic treatment for elderly patients. We recommend using a less nephrotoxic platinum if large doses of cisplatin (100mg/m2) are needed.

Respiratory compromise is a recognised sequelae of major burn injuries, and in rare instances requires extracorporeal membrane oxygenation (ECMO). Over a ten-year period, our hospital trust, an ECMO centre and burns facility, had five major burn patients requiring ECMO, whose burn injuries would normally be managed at trusts with higher levels of burn care. Three patients (60%) survived to hospital discharge, one (20%) died at our trust, and one patient died after repatriation. All patients required regular, time-intensive dressing changes from our specialist nursing team, beyond their regular duties. This review presents these patients, as well as a review of the literature on the use of ECMO in burn injury patients. A formal review of the overlap between the networks that cater to ECMO and burn patients is recommended.

Severely injured burn patients receive multiple blood transfusions for anemia of critical illness despite the adverse consequences. One limiting factor to consider alternate treatment strategies is the lack of a reliable test platform to study molecular mechanisms of impaired erythropoiesis. This study illustrates how conditions resulting in a high catecholamine microenvironment such as burns can instigate myelo-erythroid reprioritization influenced by β-adrenergic stimulation leading to anemia. In a mouse model of scald burn injury, we observed, along with a threefold increase in bone marrow LSK cells (linnegSca1+cKit+), that the myeloid shift is accompanied with a significant reduction in megakaryocyte erythrocyte progenitors (MEPs). β-Blocker administration (propranolol) for 6 days after burn, not only reduced the number of LSKs and MafB+cells in multipotent progenitors, but also influenced myelo-erythroid bifurcation by increasing the MEPs and reducing the granulocyte monocyte progenitors in the bone marrow of burn mice. Furthermore, similar results were observed in burn patients’ peripheral blood mononuclear cell-derived ex vivo culture system, demonstrating that commitment stage of erythropoiesis is impaired in burn patients and intervention with propranolol (nonselective β1,2-adrenergic blocker) increases MEPs. Also, MafB+cells that were significantly increased following standard burn care could be mitigated when propranolol was administered to burn patients, establishing the mechanistic regulation of erythroid commitment by myeloid regulatory transcription factor MafB. Overall, results demonstrate that β-adrenergic blockers following burn injury can redirect the hematopoietic commitment toward erythroid lineage by lowering MafB expression in multipotent progenitors and be of potential therapeutic value to increase erythropoietin responsiveness in burn patients.

Acute kidney injury (AKI), a critical syndrome characterized by a sudden reduction of renal function, is a common disorder among elderly patients particularly in Intensive Care Unit (ICU). AKI is closely associated with both short- and long-term mortality and length of hospital stay and is considered a predictor of chronic kidney disease (CKD). Specific hemodynamic, metabolic, and molecular changes lead to increased susceptibility to injury in the aged kidney; therefore, certain causes of AKI such as the prerenal reduction in renal perfusion or vascular obstructive conditions are more common in the elderly; moreover, AKI is often multifactorial and iatrogenic. Older patients present several comorbidities (diabetes, hypertension, heart failure) and are exposed to multiple medical interventions such as the use of nephrotoxic contrasts media and medications, which can also trigger AKI. Considering the emerging relevance of this condition, prevention and treatment of AKI in the elderly should be crucial in the internist and emergency setting. This review article summarizes the incidence, the risk factors, the pathophysiology, the molecular mechanisms and the strategies of prevention and treatment of AKI in elderly patients.

Abstract Quality of life and functional recovery after burn injury is the final goal of burn care, especially as most of burn patients survive the injury due to advanced medical science. However, dysfunction, disfigurement, contractures, psychological problems and other discomforts due to burns and the consequent scars are common, and physical therapy and occupational therapy provide alternative treatments for these problems of burn patients. This guideline, organized by the Chinese Burn Association and Chinese Association of Burn Surgeons aims to emphasize the importance of team work in burn care and provide a brief introduction of the outlines of physical and occupational therapies during burn treatment, which is suitable for the current medical circumstances of China. It can be used as the start of the tools for burn rehabilitation.
