Burn injuries are a significant public health concern, with a substantial global burden. These injuries can result in complex, life-threatening situations that require advanced management strategies. This review explores the epidemiology, significance, and advanced management of burn patients. We delve into the theoretical framework, covering definitions, risk factors, complications, and various management approaches. The discussion highlights the latest advances in burn care, including early burn wound excision, fluid resuscitation, infection control, and rehabilitation. The evolving landscape of burn care research and its implications for improved patient outcomes are emphasized. In conclusion, this article underscores the importance of a multidisciplinary approach to burn patient care and the need for continued research to enhance the quality of life for survivors.

The status quo of early burn wound excision: Insights from the German burn registry

BackgroundThere is a common, well-known and established recommendation to excise burn wounds within 24–72 h in order to mitigate the systemic inflammatory and immunomodulatory response, shorten length of hospitalization through early grafting and optimize patient survival. Despite this apparent consensus, surprisingly few systematic studies have evaluated the actual adherence to this practice and its implications on patient outcomes. In this registry study, we sought to objectify the current status of early burn wound excision, its influencing factors and impact on patient outcomes for all German burn centers. MethodsThe German burn registry (‘Deutsches Verbrennungsregister’) was queried for 3 consecutive years for all patients, who received at least one surgical intervention. Patients were stratified based on whether the first surgical procedure was performed early (EE, within 72 h) or late (LE, after 72 h) post-burn. Descriptive statistics and univariate regressions were performed to quantify fraction of EE vs. LE and to evaluate factors which might favor one over the other (i.e. age, inhalation injury, burn severity by total body surface area (TBSA), scald vs. other burns, obesity, time of admission). Key patient outcomes were analyzed for each group (i.e. mortality, length of hospitalization, number of surgeries) and multifactorial regression analyses were carried out to model the impact of EE on mortality. Statistical significance was accepted at p < 0.05. ResultsAfter initial screening, 1494 complete records were included for final analysis and were stratified into EE and LE. Only 670 (44%) underwent EE within 72 h. Increasing TBSA burned (i.e. [TBSA > 30%]: 53.8% EE, [TBSA < 30%]: 43.5% EE, p < 0.01) and admission on a weekday between Sunday and Wednesday were associated with higher probability of EE (51.5% EE) versus Thursday to Sunday (37.3%, p < 0.001). Age, inhalation injury, cause of burn, and obesity had no effect on EE vs. LE. Patients with EE had significantly shorter median lengths of hospitalization (EE: 18 d, LE: 21 d, p < 0.01). The median number of operations was comparable for both groups. Gross mortality appeared higher in the EE group, but turned out to be comparable to LE after correction for age, TBSA and sex in multifactorial regression analysis. ConclusionDespite apparent consensus among burn physicians, early excision of burn wounds is performed in less than 50% of cases in German burn centers. The relationship of EE to TBSA burned is expected and clinically sound, while a dependence on admission weekday raises administrative and infrastructural questions, especially when patients who receive EE have significantly shorter hospital stays. More analyses from other burn repositories are needed to compare and benchmark the international status quo of early burn wound excision.

Glycerolised Skin Allografts for Extensive Burns in Low- and Middle-income Countries.

Introduction:There has been a significant improvement in the outcome of treatment of large surface area burns in developed countries. A major contributory factor is an early excision and skin grafting of burn wounds. The initial coverage of large surface area deep burn wounds requires the use of temporary skin substitutes such as allografts due to limited skin autografts. Cadaveric skin allografts are the commonest source of skin allografts in use; however, there may be religious, cultural, cost, or other factors mitigating its availability and routine use in low- and middle-income countries (LMICs). Human skin allografts may be used fresh or stored in tissue banks to ensure its ready availability. The purpose of this review is to promote glycerolised skin allografts as a means of skin preservation in low-resource countries above other modalities cryopreservation due to its cost advantages and relative ease of operation.Materials and Methods:A literature search for articles related to human skin allograft use in burn care, skin banks, and glycerolised skin allografts in LMICs was done using PubMed, EMBASE, and Web of Science databases. The key words used were ‘allograft’ and ‘burn’ with a filter in the search for human studies. The relevant references in the articles obtained were also searched for and included in the reviewResults:Sixty-three journal articles were reviewed for contents in line with the objectives of this study.Conclusion:Glycerolised skin graft is a viable option for coverage of extensive burns in LMICs.

Burn wound excision within 24 h: A 9-year review

BackgroundSevere burns are accompanied by an acute and prolonged hypermetabolic response typified by elevated levels of proinflammatory cytokines and acute phase proteins. When persistent, this inflammatory response can result in multi-organ dysfunction and death. Regarded as the standard of care, early removal of devitalised tissue and eschar mitigates this hypermetabolic response. Ascertaining the optimal time point for early excision, which remains controversial, has several clinical implications. MethodsThis retrospective observational study included 836 adult thermal burns patients with total burned surface area ≥20% from all Burns Registry of Australia and New Zealand (BRANZ) Hospital sites, including the Victorian Adult Burns Service (VABS), from July 1 2009 to June 30 2018. Patients were divided into two groups, “early” and “delayed”, based on a 24-hour excision cut-off from when the injury occurred. Outcome measurements included mortality, hospital length of stay, intensive care unit length of stay, ventilation requirements and the incidence of positive blood cultures. ResultsAmong all patients at BRANZ sites, excision within 24 h was associated with reduced mean length of ICU stay (6.6 ± 8.1 vs. 9.2 ± 10.6 days; p = 0.008) and lower mean mechanical ventilator hourly use (94.9 ± 160.8 vs. 159.2 ± 219.1 h; p = 0.001) in the 20−29% TBSA sub-group. Beyond this, no significant differences were observed in outcome measurements. ConclusionsWhile it is physiologically important to perform early burn wound excision to mitigate the inflammatory response, delaying excision beyond 24 h for surgical planning, possibly up to 72 h after injury, may be a reasonable approach for certain patient groups.

Effects of Early Versus Delayed Excision and Grafting on Restoring the Functionality of Deep Burn-Injured Hands: A Double-Blind, Randomized Parallel Clinical Trial

Hand burns have major impacts on daily activities. An interdisciplinary and multifaceted approach is necessary to effectively treat these burns. Generally, hands are common sites for burn injuries. It is known that Early Excision and Grafting (EEG) of deep burn wounds can decrease scar and subsequent contracture formation compared with Delayed Excision and Grafting (DEG) method. Accordingly, this study aimed to compare the effects of these procedures on function of hands with deep burns, by using the Michigan Hand Questionnaire (MHQ). In this double-blind randomized clinical trial, we evaluated a total of 50 patients (age range: 15-70 years) with deep second-degree burns of both hands from January 2013 to December 2015. The subjects were randomly divided into two groups, treatment (EEG) and control (DEG) groups (25 patients per group). They followed up postoperatively for 3 months. MHQ was completed for each of them to determine the function of the hands, pain sensation, limitation of daily activities, overall satisfaction, and cosmetic appearance during follow-up. Data were analyzed in the groups using SPSS version 16. Baseline characteristics of the groups were matched. In early postoperation, hand functions and daily activities, gross appearance, and pain sensation were better in EEG group. After 1 and 3 months, no significant difference was detected between the groups except for patient satisfaction which was better in EEG group. Also, EEG group was associated with a significant shorter hospital stay and lower treatment costs compared with DEG group. Graft take rate was similar in both groups. EEG is recognized as the standard treatment for deep skin burns, but we did not find any significant difference between effects of EEG and DEG on hand functions although EEG group had shorter hospital stay and lower treatment costs compared with DEG. The main goal of treatment of hand burns is restoration of the hand functions. Based on our findings, hand function was not related to the type of surgery. Also, as all wounds in both surgical groups healed less than 3 weeks, the authors suggest that the excision time limit could be change in our burn center from 10 days to 2 to 3 weeks when we use sheet graft as for hands.

Burn injury: Challenges and advances in burn wound healing, infection, pain and scarring.

Severe burn injuries are the most traumatic and physically debilitating injuries affecting nearly every organ system and leading to significant morbidity and mortality. Early burn wound excision and skin grafting are common clinical practices that have significantly improved the outcomes for severe burn injured patients by reducing mortality rate and days of hospital stay. However, slow wound healing, infection, pain, and hypertrophic scarring continue to remain a major challenge in burn research and management. In the present article, we review and discuss issues in the current treatment of burn injuries; the advances and novel strategies developed in the past decade that have improved burn management; and also, pioneer ideas and studies in burn research which aims to enhance burn wound care with a focus on burn wound infection, pain management, treatments for scarring and skin tissue engineering.

Transfusion requirements in burn patients undergoing primary wound excision: effect of tranexamic acid.

Early excision of burn wounds is the standard approach for burns, but it is usually associated with the need of allogeneic blood transfusion. Our aim was to determine if intravenous administration of tranexamic acid (TXA) was able to reduce packed red blood cell (pRBC) transfusion requirements in burn patients. We conducted a retrospective cohort study of 2 consecutive series of severely burned patients (≥20% total body surface are) admitted for primary burn surgery. We searched for differences in pRBC transfusion occurrence and requirements during surgery and up to 24 hours after surgery. A total of 107 patients were included in the study, and 48.6% (52 patients) received TXA during primary excision. The use of TXA exhibited an absolute risk reduction in the need for transfusion during surgery of 24.2% (95% CI: 7.1-41.4%). In total, patients receiving TXA required 1.6 units of pRBC in the perioperative period vs. 2.6 units in those not receiving TXA (P=0.017). The intraoperative use of TXA in burn patients undergoing primary burn excision reduced the incidence of allogeneic transfusion and the total number of pRBC transfused.

Infections in critically ill burn patients

Severe burn patients are one subset of critically patients in which the burn injury increases the risk of infection, systemic inflammatory response and sepsis. The infections are usually related to devices and to the burn wound. Most infections, as in other critically ill patients, are preceded by colonization of the digestive tract and the preventative measures include selective digestive decontamination and hygienic measures. Early excision of deep burn wound and appropriate use of topical antimicrobials and dressings are considered of paramount importance in the treatment of burns.Severe burn patients usually have some level of systemic inflammation. The difficulty to differentiate inflammation from sepsis is relevant since therapy differs between patients with and those without sepsis. The delay in prescribing antimicrobials increases morbidity and mortality. Moreover, the widespread use of antibiotics for all such patients is likely to increase antibiotic resistance, and costs. Unfortunately the clinical usefulness of biomarkers for differential diagnosis between inflammation and sepsis has not been yet properly evaluated.Severe burn injury induces physiological response that significantly alters drug pharmacokinetics and pharmacodynamics. These alterations impact antimicrobials distribution and excretion. Nevertheless the current available literature shows that there is a paucity of information to support routine dose recommendations.

Stromal vascular fraction improves deep partial thickness burn wound healing

ObjectiveThe practice of early burn wound excision and wound closure by immediate autologous skin or skin substitutes is the preferred treatment in extensive deep partial and full-thickness burns. To date there is no proven definite medical treatment to decrease burn wound size and accelerate burn wound healing in modern clinical practice. Stromal vascular fraction is an autologous mixture that has multiple proven beneficial effects on different kinds of wounds. In our study, we investigated the effects of stromal vascular fraction on deep partial-thickness burn wound healing. MethodsIn this study, 20 Wistar albino rats were used. Inguinal adipose tissue of the rats was surgically removed and stromal vascular fraction was isolated. Thereafter, deep second-degree burns were performed on the back of the rats by hot water. The rats were divided into two groups in a randomized fashion. The therapy group received stromal vascular fraction, whereas the control group received only physiologic serum by intradermal injection. Assessment of the burn wound healing between the groups was carried out by histopathologic and immuno-histochemical data. ResultsStromal vascular fraction increased vascular endothelial growth factor, proliferating cell nuclear antigen index, and reduced inflammation of the burn wound. Furthermore, vascularization and fibroblastic activity were achieved earlier and observed to be at higher levels in the stromal vascular fraction group. ConclusionsStromal vascular fraction improves burn wound healing by increasing cell proliferation and vascularization, reducing inflammation, and increasing fibroblastic activity.

Burns at KCMC: Epidemiology, presentation, management and treatment outcome

BackgroundAbout 90% of the global burden of burns occurs in the low and middle income countries. In Africa it is estimated that between 17,000 and 30,000 children under five die each year due to burns. In Tanzania there are no specialized burn centers. Burn patients are often managed in the general surgical wards in most hospitals. Kilimanjaro Christian Medical Centre is one of the four tertiary referral hospitals in Tanzania. RationaleThis study aimed to review the epidemiology presentation management and outcome of burn patients in this challenging environment. Patients and methodsA cross-sectional prospective study involving 41 patients was undertaken from October 2011 to April 2012. Results65.9% were males. The largest age group was below 5 years (36.6%). 19.5% were epileptic. More than half of the burns were due to open flame. 80.5% had second degree burns. 56.1% had a BSA of 15% or less and 56.1% had an APACHE score of 10 or less. It was found that 73.2% of burns occurred at home. The commonest prehospital first aid applied was honey. Only 41.5% arrived in hospital within the first 24h after burn. Among the 14.6% who had skin grafting, none had early excision of burn wound. 53.7% developed wound sepsis while 24.4% developed contractures. The mortality rate was 26.8%. ConclusionChildren under five are the worst affected by burns. Most patients had second degree burn wounds. Inappropriate management of the burn wound started just after injury and continued even in hospital. Mortality and complication rates are high.

Development of a long-term ovine model of cutaneous burn and smoke inhalation injury and the effects of early excision and skin autografting

Smoke inhalation injury frequently increases the risk of pneumonia and mortality in burn patients. The pathophysiology of acute lung injury secondary to burn and smoke inhalation is well studied, but long-term pulmonary function, especially the process of lung tissue healing following burn and smoke inhalation, has not been fully investigated. By contrast, early burn excision has become the standard of care in the management of major burn injury. While many clinical studies and small-animal experiments support the concept of early burn wound excision, and show improved survival and infectious outcomes, we have developed a new chronic ovine model of burn and smoke inhalation injury with early excision and skin grafting that can be used to investigate lung pathophysiology over a period of 3 weeks. Materials and methodsEighteen female sheep were surgically prepared for this study under isoflurane anesthesia. The animals were divided into three groups: an Early Excision group (20% TBSA, third-degree cutaneous burn and 36 breaths of cotton smoke followed by early excision and skin autografting at 24h after injury, n=6), a Control group (20% TBSA, third-degree cutaneous burn and 36 breaths of cotton smoke without early excision, n=6) and a Sham group (no injury, no early excision, n=6). After induced injury, all sheep were placed on a ventilator and fluid-resuscitated with Lactated Ringers solution (4mL/% TBS/kg). At 24h post-injury, early excision was carried out to fascia, and skin grafting with meshed autografts (20/1000in., 1:4 ratio) was performed under isoflurane anesthesia. At 48h post-injury, weaning from ventilator was begun if PaO2/FiO2 was above 250 and sheep were monitored for 3 weeks. ResultsAt 96h post-injury, all animals were weaned from ventilator. There are no significant differences in PaO2/FiO2 between Early Excision and Control groups at any points. All animals were survived for 3 weeks without infectious complication in Early Excision and Sham groups, whereas two out of six animals in the Control group had abscess in lung. The percentage of the wound healed surviving area (mean±SD) was 74.7±7.8% on 17 days post-surgery in the Early Excision group. Lung wet-to-dry weight ratio (mean±SD) was significantly increased in the Early Excision group vs. Sham group (p<0.05). The calculated net fluid balance significantly increased in the early excision compared to those seen in the Sham and Control groups. Plasma protein, oncotic pressure, hematocrit of % baseline, hemoglobin of % baseline, white blood cell and neutrophil were significantly decreased in the Early Excision group vs. Control group. ConclusionsThe early excision model closely resembles practice in a clinical setting and allows long-term observations of pulmonary function following burn and smoke inhalation injury. Further studies are warranted to assess lung tissue scarring and measuring collagen deposition, lung compliance and diffusion capacity.

Early excision and skin grafting versus delayed skin grafting in deep hand burns (a randomised clinical controlled trial)

Introduction Early excision and grafting (E&G) of burn wounds has been reported to decrease hospital stay, hospital costs and septic complications, and some purport reduced mortality while decreasing hospital costs. In today's practice, all burn wounds unlikely to achieve spontaneous closure within 3 weeks are excised and grafted. Early studies did not demonstrate dramatic differences in cosmetic or functional results. This is particularly true with burns of the face, hands and feet. In this study, early excision and skin grafting was compared with delayed skin grafting in deep hand burns. Materials and methods From September 2006 to February 2008, 50 patients with hand burns and average burn size less than 30% total body surface area (TBSA) deep second- and third-degree were randomly divided into early E&G group (group I) and delayed grafting group (group II). Gradual and careful limb and digit range of motion was started on about 10th–14th postoperative day. We used a questionnaire based on the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire to evaluate final functional outcome. Further, hypertrophic scar formation, contracture and deformities were followed and managed accordingly. Results The most common site of involvement was the metacarpophalangeal (MCP) joint with frequency of 39% and 40% in groups I and II, respectively. There were no statistically significant differences between both groups regarding deformity severity, scar formation, sensation, major activities and overall satisfaction. Discussion In treating burns of the hand, the primary goal should always be to restore the functionality of the hand. Although early surgery shortens the healing time and lessens the hospital stay, our results did not show any significant difference between these two methods regarding the function, scar formation, daily activity limitation and overall satisfaction.

The optimal time for early burn wound excision to reduce pro-inflammatory cytokine production in a murine burn injury model

Background A potential solution to prevent post-burn deleterious inflammatory responses is early burn wound excision. However, the most beneficial time point remains controversial. This animal study investigated the optimal time point for burn wound excision to reduce pro-inflammatory cytokines production after burn. Methods Forty-eight male Sprague-Dawley rats received scald burns with third-degree burns of 30% body surface area, and were then divided into eight groups by day of operation for excision. Group 1 ( n = 6) received burn eschar excision on post-burn day (PBD) 1. Group 2 received excision on PBD2 ( n = 6) and so on, while group 8 was the control group ( n = 6) that did not undergo excision. The skin defect after excision was covered with a bovine-derived collagen dressing. Interleukin-1 (IL-1), IL-6, IL-10 and tumour necrosis factor-α were serially analysed by enzyme-linked immunosorbent assay (ELISA). Results We found that levels of all pro-inflammatory cytokines appeared to be lower after excision of full-thickness burns, but as the excision time was delayed from group 1 to group 7, the differences showed progressive decline. Conclusions We believe that the earlier the excision is performed, the more the level of pro-inflammatory cytokines can be lowered, and the better the post-burn inflammatory process can be modulated.

Burns demand our attention

An extensive burn injury is one of the most devastating conditions encountered in medicine. It severely impacts the physical, physiological, psychological, social and financial status of not only the victim but that of his entire family. Better understanding of pathophysiology, early burn wound excision and provision of skin cover, development of newer skin substitutes and equivalents, and remarkably improved anaesthetic procedures, ICU care and ventilation have surely contributed to better survival statistics of a thermally injured individual. But despite so many advances, the ultimate goal of making a burn victim functionally independent and aesthetically acceptable to achieve the societal reintegration and return to profession still remains a long cherished but elusive goal for majority of the burn survivors even in the developed world. Statistics prove that developing countries have a huge load of burn injuries (estimated 6–7 million new cases per year in India) with majority of thermally injured victims being primarily managed in the peripheral hospitals. Private sector does not have many established and functioning burn units. Very few can afford the exorbitant cost of treatment at the corporate set up. Moreover, a large number of victims are from low socioeconomic status and are not insured either. The National Programme for Prevention of Burn Injuries is also not yet in place in our country. In India, meagerly equipped government hospitals bear the brunt of this massive load. At many places, even the services of all the members of the multidisciplinary team are also not available. Despite this entire crunch, such a massive load has been managed for years by plastic surgeons and general surgeons of these government hospitals. Besides the surgeon, the credit must also go to the selfless and dedicated service of the staff, especially the resident doctors and the nursing personnel. These overworked and underappreciated vital cogs are intimately associated with the day to day care of these patients in the casualty, burn wards, OTs, OPD, physiotherapy, etc. Staying abreast with the recent trends simultaneously keeping basic fundamentals firmly in place is essential for all the members of the burn team. The dedicated manuals/texts/journals play a major role in this aspect. This special supplement of Indian Journal of Plastic Surgery (IJPS) is aimed for this very purpose. A broad range of topics have been chosen for this issue. We shall remain indebted to our national and overseas contributors, all of whom have loads of experience and are leaders in their respective fields. They have done a magnificent job of bringing together the most current information regarding various aspects of burn management. The reading of this volume makes a comprehensive review of the subject and we are hopeful that it shall be useful for the residents and the teachers alike. In recent times, aesthetic surgery has taken such a lead in the minds of young plastic surgeons that burn management has been literally overlooked as a discreet topic. ‘Burn care’, despite being such a vast specialty within the super specialty of Plastic Surgery, is assigned just one session in the four-and-a-half day long National Plastic Surgery meetings! In this era of highly lucrative cosmetic surgery, the editorial staff at IJPS needs to be complimented for having dedicated the entire issue to the cause of burns. Wish you all a ‘happy and pleasant’ reading.

Early wound excision and skin grafting restores cellular immunity after severe burn trauma.

Suppression of cellular immunity following thermal injury may contribute to the high incidence of postburn sepsis. Early excision and skin grafting may remove deleterious local wound factors and prevent immunosuppression. The effect on cellular immunity of early burn wound excision and skin grafting was investigated in an animal model using female Wistar rats. The development of immunosuppression shortly after burn injury was shown by popliteal lymph node assay and a 2,4-dinitrofluorobenzene skin reaction test. Excision and skin grafting 2 days after burn trauma restored parameters to normal. Burned tissue suppresses cellular immunity; this effect is preventable by early excision and skin grafting.

A hypothesis of the healing of deep dermal burns and the significance for treatment.

Deep dermal burns heal by a combination of new connective tissue formation (granulation) and epithelialization. In deep dermal wounds, which are unhealed after 14 days of conservative treatment, epithelialization can be enhanced by abrasion either alone or combined with provision of a skin graft. Some 42 burn wounds in 25 patients treated by this method have healed quickly and with good results. This method represents a move away from the current trend of early tangential excision and grafting of burn wounds and raises the possibility of developing a regime with the advantages but not the disadvantages of early tangential excision and grafting.

The Pharmacologic Modulation of the Hypermetabolic Response to Burns

Patients with burns less than 40% TBSA do not have catabolism unless sepsis develops. Those with burns more than 40% TBSA always experience catabolism, which causes metabolic derangements that persist for at least 1 year after the injury in most body tissues. The accomplishments of the past decade have placed us in the midst of an exciting paradigm shift from what used to be a primary concern (ie, mortality) to areas that are more likely to enhance the quality of life of burn survivors. Modulating postburn hypermetabolism for the burned patient is of overwhelming importance in both the immediate care stage and the rehabilitative stage. Postburn hypermetabolism cannot be completely reversed but may be manipulated by nonpharmacologic and pharmacologic means. Early burn wound excision and complete wound closure, prevention of sepsis, the maintenance of thermal neutrality for the patient by elevation of the ambient temperature, and graded resistance exercises during convalescence are simple, highly effective primary treatment goals. Although the initial burn injury and sepsis-related complications principally determine the extent of the metabolic response in burn victims, obligatory activity, background- and procedural-related pain, and anxiety also greatly increase metabolic rates. Judicious maximal narcotic support, appropriate sedation, and supportive psychotherapy are mandatory if their effects are to be minimized. Several anabolic and anticatabolic agents are available for use during immediate care and rehabilitation. Exogenous, continuous low-dose insulin infusion, beta-blockade with propranolol, and the use of the synthetic testosterone analogue oxandrolone are the most cost-effective and least toxic therapies to date. These greatly assist therapeutic minimization of the loss of lean body mass and linear growth delay and are effective in burned patients with and without sepsis. Adverse effects, cost benefits, and the ease of administration and monitoring must be examined when considering the possibility of their use.

The epidemiology of burn wound infections: then and now.

Burn wound infections are a serious complication of thermal injury. Although pneumonia is now the most important infection in patients with burns, burn wound infection remains a serious complication unique to the burn recipient. The methods for managing thermal injury have evolved during the past 50 years. This evolution has been accompanied by changes in the etiology, epidemiology, and approach to prevention of burn wound infections. In the 1950s, 1960s, and 1970s and into the mid-1980s, burn wounds were treated by the exposure method, with application of topical antimicrobials to the burn wound surface and gradual debridement with immersion hydrotherapy. As early burn wound excision and wound closure became the focal point of burn wound management, accompanied by a change from immersion hydrotherapy to showering hydrotherapy, the rate of burn wound infection appeared to decrease. Few epidemiologic studies have been done since this change in the approach to management of thermal injury. There are few data on the epidemiology of burn wound infections from the era of early excision and closure. Data are needed on infection rates for excised and closed burn wounds, the etiologies of these infections, and the epidemiology and the prevention of such infections. Additional studies are needed on the indications for topical and antimicrobial prophylaxis and selective decontamination of the digestive tract.

Burn injuries

To summarize new advances and research findings that relate to the treatment of burn victims. Recent advances in burn resuscitation and critical care reflect a better understanding of the acute phase pathophysiology of severe burns. Aggressive management of the unstable burn airway is always the most important clinical priority. Emphasis has been placed on the early identification of inhalation injury and its impact on fluid resuscitation, as well as on a protective lung strategy to reduce the development of pulmonary edema, acute lung injury and pneumonia, and to reduce the risk of barotrauma. New blood markers, such as serum cholinesterase and inflammatory cytokines, have been introduced to assist in the prognosis of morbidity and mortality, beyond the traditional vital signs. At this time, however, these are available only for research purposes. Finally, early burn wound excision and coverage with new biodegradable materials results in less pain and more rapid healing for the patient. The combination of innovative approaches and a dedicated burn team is expected to continue to improve survival in the next few years even in the most severe cases.
