Macedo-Viñas M, Lucas A. Evolution of Microbial Flora Colonizing Burn Wounds during Hospitalization in Uruguay. Biomedicines 2023; 11:2900. [PMID: 38001901 PMCID: PMC10669172 DOI: 10.3390/biomedicines11112900] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2023] [Revised: 10/16/2023] [Accepted: 10/20/2023] [Indexed: 11/26/2023] Open
Abstract
(1) Background: Infections are a main cause of morbidity and mortality among burn patients. The spectrum of microorganisms depends on the epidemiological context and treatment practices. We aimed to describe the evolution of microbial flora colonizing burn wounds among patients hospitalized during 15 or more days at the National Burn Center in 2015. (2) Methods: Demographic data, length of stay, total body surface area burn, and status at discharge were collected from electronic records and culture results from the laboratory database. (3) Results: Among 98 included patients, 87 were colonized. The mean length of stay was 39 days overall and 16 days in the ICU. Acinetobacter spp., Enterococcus spp., and Staphylococcus aureus predominated. Fifty-six patients harbored multidrug-resistant bacteria and had a significantly greater TBSA. The mean time to colonization was 6 days overall and 14 days for multidrug-resistant bacteria; it was significantly longer for methicillin-resistant S. aureus than for methicillin-susceptible S. aureus. (4) Conclusions: This is the first report describing the dynamics of microbial colonization of burn wounds in Uruguay. Similarities were found with reports elsewhere, but early colonization with yeasts and the absence of Streptococcus pyogenes were unique. Each burn center needs to monitor its microbial ecology to tailor their antimicrobial strategies effectively.

Microbiology and clinical characteristics of industrial oil burns. Burns 2019; 46:711-717. [PMID: 31761453 DOI: 10.1016/j.burns.2019.10.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2019] [Revised: 09/14/2019] [Accepted: 10/02/2019] [Indexed: 11/20/2022]
Abstract
INTRODUCTION Infections complicating burns generally transition from Gram-positive to Gram-negatives over the first couple weeks, but this depends on multiple factors. The microbiology of infections complicating crude oil (CO) and hydraulic fracturing (FRAC) burns is unknown. METHODS We performed a retrospective study of patients with industrial thermal burns hospitalized >2 days with ≥1 day in the ICU between 4/2011-11/2016. Burns were oil-related (ORB; CO or FRAC) or non-oil related (NORB). Epidemiology and microbiology during the first 15 hospital days was compared. RESULTS 149 patients were included, with 11 FRAC and 24 CO. CO burns were more severely burned than those with FRAC and NORB (p<0.05). Mortality was 17% and 18% for CO and FRAC burns compared to 3% in NORB (p<0.01). More cultures were obtained from ORB than NORB (p<0.05). ORB were associated with Stenotrophomonas maltophilia and FRAC associated with Serratia marcescens and Candida glabrata. Patients with FRAC, CO and NORB had a median of 13, 3.5, and 4 days to first positive culture respectively (p=0.03). CONCLUSION ORB were associated with more severe burns and unique microbiology. FRAC burns had longer to initial positive culture, potentially suggesting our current methodology is inadequate to diagnose infections associated with FRAC.

Abstract
Background: Infectious complications are one of the most life-threatening complications and result in substantial mortality and morbidity in children who have been burned. The goal of the study is to assess the risk factors for sepsis in pediatric burn patients in a referral hospital. Methods: This study was performed at the Pediatric Burn Unit of Ankara Child Health and Diseases Hematology Oncology Training and Research Hospital during the period between January 2014 and June 2017. The patients were evaluated for age, sex, burn etiology, burned body surface area (BSA), the presence of inhalation injury, sepsis, positive cultures, the micro-organisms cultured samples, and septic focus. Results: A total of 181 patients were included in the study. The most common cause of burns was scalds in 120 patients (66.3%). Forty-one patients (22.7%) developed health-care-associated infection and sepsis. Gram-negative micro-organisms were isolated in 40 (97.6%) patients (Acinetobacter spp., Pseudomonas aeruginosa, Klebsiella pneumonia) with sepsis. Carbapenem resistance was detected in 31 (93.8%) of 40 patients. Mortality was observed in 11 patients (6.1%) in the group with sepsis. Burn surface area, burn depth, C-reactive protein (CRP) values, mortality, Garcés index, and Baux index were higher in the group with sepsis (p < 0.05). Multiple regression analysis revealed that mechanism of injury (flame), burned BSA ≥25%, C-reactive protein ≥6 mg/dL (area under the curve [AUC]: 0.76 p < 0.001 and AUC: 0.90, p < 0.001, respectively) at admission were independent parameters for development of sepsis in pediatric burn patients. Conclusion: Multi-drug-resistant Pseudomonas aeruginosa and Acinetobacter baumannii were important agents of blood stream infection in burned children. Burned BSA ≥25% and CRP ≥6 mg/dL were risk factors for developing sepsis in pediatric burn patients.

[PMID: 28589152 PMCID: PMC5457798 DOI: 10.1186/s41038-017-0083-y] [Citation(s) in RCA: 28] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/06/2017] [Accepted: 05/22/2017] [Indexed: 01/14/2023]
Abstract
Background There is increasing evidence that sex differences may influence responses after thermal injury and affect clinical outcomes. The objective of this study was to evaluate the relationships between sex, thermal injury, body size, and inpatient mortality in burn patients. Methods Medical records of adults with >20% total body surface area (TBSA) burn injury admitted to two American Burn Association (ABA)-verified burn centers between 2008 and 2014 were retrospectively reviewed. Injury details and baseline characteristics, including body size as estimated by body surface area (BSA) and body mass index (BMI) were recorded, along with details of the hospital course. The primary outcome of inpatient mortality was compared between sexes. Results Out of 334 subjects, 60 were women (18%). Median TBSA was 33% (IQR 25–49) in this cohort, with 19% full thickness burns and 30% inhalation injury. Despite no significant difference in age, presence of inhalation injury, TBSA, or depth of burn, women had significantly higher rates of inpatient mortality (45 vs. 29%, P = 0.01). BSA was significantly lower in women vs. men (P < 0.001), but this difference was not more pronounced among non-survivors. There was no difference in BMI between men and women non-survivors. Although not significant (P = 0.28), women succumbed to their injuries sooner than men (day 4 vs. 10 post-injury). Conclusions Women are less likely to survive burn injuries and die sooner than men with similar injuries. Body size does not appear to modulate this effect. Burn centers should be aware of the higher mortality risk in women with large burns.

A comparison between occlusive and exposure dressing in the management of burn wound. Burns 2016; 42:578-82. [PMID: 26970838 DOI: 10.1016/j.burns.2015.05.001] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2014] [Revised: 04/29/2015] [Accepted: 05/04/2015] [Indexed: 11/20/2022]
Abstract
BACKGROUND AND AIM Two types of dressing, occlusive and exposure dressing, are commonly used in burn units. A dressing is said to be occlusive if a moist wound surface is maintained when the dressing is in place. This study was designed to compare the effectiveness of occlusive and exposure dressing in controlling burn infections. PATIENTS AND METHODS Two hundred patients with second-degree burns admitted to Mottahari Hospital, Tehran, Iran, over a period of 12 months from May 2012 to May 2013 were studied. They were divided into two groups of 100 each, to receive either occlusive or exposure dressing. During the first week of treatment, wound specimens were obtained by sterile swab and cultured in selective media. Demographics (age and gender), burn areas, cause of burn, length of hospital stay (LOS), type of infections and time to total healing were compared between the two groups. RESULTS Occlusive dressing was more susceptible to microbial contamination and infections than exposure dressing. The mean duration of treatment based on epithelialization and healing in occlusive dressing was longer than for exposure dressing. The most common isolate was Pseudomonas spp., followed by Enterobacter, Escherichia coli, Staphylococcus aureus, Acinetobacter, and Klebsiella spp. CONCLUSIONS Exposure dressing was more suitable than occlusive dressing for treating partial-thickness at our center. Pseudomonas aeruginosa was the most common organism encountered in burn infection.

Abstract
OBJECTIVE The present study aimed to investigate the combined effects of puerarin with edaravone on inhalation lung injury induced by black gunpowder smog. MATERIALS AND METHODS Male Wistar rats were divided into five groups (control group, edaravone group, puerarin group, edaravone combined with puerarin group and inhalation group). The severity of pulmonary injuries was evaluated after inducing acute lung injury. Arterial blood gas, inflammatory cytokines, biochemical, parameters, cell counting, W/D weight ratio and histopathology were analyzed. Results in lung tissues, either edaravone or puerarin treatment alone showed significant protective effects against neutrophil infiltration and tissue injury, as demonstrated by myeloperoxidase activity and histopathological analysis (all p<0.05). In addition, combined treatment with both edaravone and puerarin demonstrated additive protective effects on smog-induced lung injury, compared with single treatment. CONCLUSIONS Combination of edaravone and puerarin shows promise as a new treatment option for acute lung injury/acute respiratory distress syndrome patients.

Abstract
BACKGROUND The burn eschar serves as a medium for bacterial growth and a source of local and systemic infection. To prevent or minimize these complications, it is important to debride the eschar as early as possible. OBJECTIVE To identify the presence of viable skin within the excisions by examining tangentially excised burn eschars. METHODS A total of 146 samples of burned human tissue were removed during 54 routine sharp tangential excision procedures (using dermatomes). The samples were histologically examined to identify the relative thickness of the dead, intermediate and viable layers. RESULTS The mean (± SD) thickness of the excised samples was 1.7 ± 1.1 mm. The sacrificed viable tissue (mean thickness 0.7+0.8 mm) occupied 41.2% of the entire thickness of the excision. In 32 biopsies (21.8%; 95% CI 16.0 to 29.3), the excision did not reach viable skin. Only eight biopsies (5.4%; 95% CI 2.8 to 10.1) contained all of the necrotic tissue without removing viable tissue. CONCLUSIONS The thickness of a single tangentially excised layer of eschar is not much greater than the actual thickness of the entire skin and often contains viable tissue. Because surgical debridement is insufficiently selective, more selective means of debriding burn eschars should be explored.

Contribution of bacterial and viral infections to attributable mortality in patients with severe burns: an autopsy series. Burns 2010; 36:773-9.

Abstract
Bacterial infections are a common cause of mortality in burn patients and viral infections, notably herpes simplex virus (HSV) and cytomegalovirus (CMV) have also been associated with mortality. This study is a retrospective review of all autopsy reports from patients with severe thermal burns treated at the US Army Institute of Research (USAISR) burn unit over 12 years. The review focused on those patients with death attributed to a bacterial or viral cause by autopsy report. Of 3751 admissions, 228 patients died with 97 undergoing autopsy. Death was attributed to bacteria for 27 patients and to virus for 5 patients. Bacterial pathogens associated with mortality included Pseudomonas aeruginosa, Escherichia coli, Klebsiella pneumoniae and Staphylococcus aureus. This association with mortality was independent of % total body surface area burn, % full-thickness burn, inhalation injury, and day of death post-burn. Bloodstream infection was the most common cause of bacteria related death (50%), followed by pneumonia (44%) and wound infection (6%). Time to death following burn was < or =7 days in 30%, < or =14 days in 59% and < or =21 days in 67%. All of the viral infections associated with mortality involved the lower respiratory tract, HSV for 4 and CMV for 1. Four of these 5 patients had evidence of inhalation injury by bronchoscopy, all had facial and neck burns, and 2 had concomitant Staphylococcus pneumonia. Time to death following burn ranged from 14 to 42 days for the 5 patients. Despite advances in care, gram negative bacterial infections and infection with S. aureus remain the most common cause of bacteria related mortality early in the hospital course. Viral infections are also associated with mortality and numbers have remained stable when compared to data from prior years.

Abstract
Considerable advancements in shock resuscitation and wound management have extended the survival of burned patients, increasing the risk of serious infection. We performed a 6-year review of bacteria identification and antibiotic susceptibility records at the US Army Institute of Surgical Research Burn Center between January 2003 and December 2008. The primary goal was to identify the bacteria recovered from patients with severe burns and determine how the bacteriology changes during extended hospitalization as influenced by population and burn severity. A total of 460 patients were admitted to the burn ICU with 3507 bacteria recovered from 13,727 bacteriology cultures performed. The most prevalent organisms recovered were Acinetobacter baumannii (780), Pseudomonas aeruginosa (703), Klebsiella pneumoniae (695) and Staphylococcus aureus (469). A. baumannii was most often recovered from combat-injured (58%) and S. aureus the most frequent isolate from local (46%) burn patients. Culture recovery rate of A. baumannii and S. aureus was highest during the first 15 hospital days (73% and 71%); while a majority of P. aeruginosa and K. pneumoniae were recovered after day 15 (63% and 53%). All 4 pathogens were recovered throughout the course of hospitalization. A. baumannii was the most prevalent pathogen recovered from patients with total body surface area (TBSA) burns less than 30% (203) and 30-60% (338) while P. aeruginosa was most prevalent in patients with burns greater than 60% TBSA (292). Shifting epidemiology of bacteria recovered during extended hospitalization, bacteriology differences between combat-injured and local burn patients, and impact of % TBSA may affect patient management decisions during the course of therapy.

Abstract
BACKGROUND Approximately 5% of combat-related injuries include burns. Previous studies have shown similar mortality rates between military and civilian burn casualties; but causes of death were not detailed. STUDY DESIGN We retrospectively reviewed autopsy reports of patients with burns treated at the US Army Institute of Surgical Research Burn Center from 2004 to 2007. RESULTS Of 1,255 admissions, 100 (8%) died, with autopsies performed on 74 (36 burned during military operations). Causes of death included infection (61%); disorders of the pulmonary (55%), cardiac (36%), renal (27%), gastrointestinal (27%), and central nervous (11%) systems; and multiorgan dysfunction (15%). Patients burned as a result of military operations were younger men with more associated inhalation injuries, greater severity of injury, and longer time from injury to admission and to death. They died more frequently of infection (notably fungus, Pseudomonas, and Klebsiella) and gastrointestinal complications; and those not burned in military operations had greater numbers of cardiac and renal causes of death. CONCLUSION Casualties of military operations are clinically different and die from different causes than patients not burned during military operations. The differences are likely reflective of a younger population, with greater severity of illness and longer times from injury to admission. Therapeutic interventions should focus on prevention of infection and gastrointestinal catastrophes in military burn casualties, which are similar to younger burn patients in the US, and minimizing cardiac complications in civilian burn casualties, who are typically older patients and possibly reflective of patients with more comorbidities.

Abstract
Pulmonary complications remain one of the leading causes of mortality in patients with burns. We report two cases of adult patients with thermal and inhalation injuries who were placed on extracorporeal membrane oxygenation (ECMO) and survived. Patient 1 was a 42-year-old male who suffered 15% TBSA and a severe inhalation injury requiring intubation upon arrival to the emergency department. Patient 2 was a 24-year-old female in a house fire who received 20%TBSA and was noted to be in respiratory distress and intubated on the scene by the paramedic team. Three days after admission, patient 1 developed severe respiratory failure. He decompensated, despite maximum conventional management, and was placed on ECMO. After 300 hours of ECMO, his pulmonary function had improved, and he was decannulated. Patient 2 also developed severe refractory respiratory failure and was placed on ECMO. She was decannulated 288 hours later. Both patients were discharged home shortly afterwards and have managed well. ECMO should be considered when patients are facing a respiratory death from inhalation injury on conventional mechanical ventilation.

Abstract
OBJECTIVE To show the effectiveness of an integrated therapeutical approach in a severe case of acute respiratory distress syndrome (ARDS) following burns, inhalation injury with therapy-refractory oxygenation under maximized ventilatory settings, and an overall complicated clinical course. PATIENT AND METHODS Case report of a patient with severe inhalation injury and burns in an intensive care unit setting, undergoing cardiopulmonary resuscitation (CPR), nitric oxide (NO)-inhalation, surfactant-, kinetic-, and urodilatin-therapy. CASE REPORT A 15-year-old male presented with deep dermal and full thickness thermal injuries involving 25% of his total body surface area. Shortly after presentation, the patient developed therapy-refractory respiratory failure, cardiac arrest, and subsequently suffered five-organ system failure (lung, heart, gastrointestinal, liver, kidney), in addition to burn injury, and ischemia related cerebral lesions. The patient was successfully treated with cardiac resuscitation, extra corporeal membrane oxygenation (ECMO), NO, kinetic therapy, surfactant, urodilatin, and other standard intensive care regimens. Three months post-trauma the patient was discharged home, nearly fully recovered. CONCLUSIONS In a patient with severe ARDS, oxygenation failure under maximized ventilatory settings, and subsequent five-organ system failure, an integrated therapeutical approach comprising ECMO, NO, kinetic therapy, surfactant, and urodilatin did cross-bridge respiratory and vital functions, enabling overall survival.

Abstract
Pulmonary failure remains the major determinant of mortality and morbidity following burn injury. We hypothesized that intratracheal instillation of perfluorocarbon liquids could be a therapeutic measure in combination with conventional mechanical ventilation to improve pulmonary gas exchange in acute respiratory distress syndrome with thermal injury. Forty-five New Zealand rabbits were used for this prospective and randomized experimental study. The animals were burned by scald to reach full-thickness 40% burn surface area. After inducing respiratory distress by repeated lung lavage with saline, animals were divided randomly into three groups of 15 rabbits each. First group (control group) received conventional treatment (continuous positive-pressure ventilation) using a FiO(2) of 1.0, tidal volume of 12 ml/kg, respiratory frequency of 30 cycles/min and PEEP of 6 cm H(2)O. Second group was treated with 9 ml/kg of intratracheal perfluorocarbon. Third group was treated with 15 ml/kg of intratracheal perfluorocarbon. All groups were ventilated for 6 h. In the perfluorocarbon groups, PaO(2) increased significantly (P<0.05) from 46+/-4 to 439+/-10 mmHg compared to the control group in a dose-related manner. In pulmonary parameters we observed significant (P<0.05) decrease in mean airway pressures from the pre-treatment value of 11.44+/-0.15 cm H(2)O to the post treatment 10.22+/-0.12 cm H(2)O and increase (P<0.05) in respiratory system compliance from 1.8+/-0.02 to 2.46+/-0.07 ml/cm H(2)O with the perfluorocarbon. Perfluorocarbon instillation did not result in statistically significant changes in arterial pressure, heart rate and central venous pressure. In conclusion, partial liquid ventilation with perfluorocarbon is a new technique leading to a marked and sustained improvement in oxygenation and pulmonary function in an experimental model of ARDS in burns.

Abstract
Adult respiratory distress syndrome (ARDS) has been the major cause of mortality in burn injury. The authors reported the experience of using extracorporeal membrane oxygenation (ECMO) to treat adult burn patient with ARDS. Three patients with burn or electric injury, around 48.9% of body surface area over second-degree burns, developed ARDS after resuscitation. All had positive blood culture and depended on a ventilator more than 5 days before ECMO. Venovenous (VV) ECMO was started at the beginning of severe respiratory failure with an oxygen index of 61.6 +/- 15.5 cm H2O/mm Hg (> or =40 cm H2O/mm Hg), partial arterial oxygen tension to inspired oxygen fraction (Pa(O2)/Fi(O2)) of 46.1 +/- 7.0 mm Hg (< or =200 mm Hg), positive end expiratory pressure (PEEP) of 15.7 +/- 1.6 cm H2O (> or =10 cm H2O), alveolar-arterial difference in oxygen concentration (A-a D(O2)) of 618.9 +/- 19.3 mm Hg (> or =300 mm Hg), and lung compliance of 17.3 +/- 4.6 ml/cm H2O (< or =30 ml/cm H2O). The VV type had to be converted to the newly designed veno-venoarterial (V-VA) ECMO due to the myocardial dysfunction. Two of three patients survived. The duration of ECMO was 160.2 +/- 51.1 h. Two patients received debridement of escar during ECMO support and desmopressin infusion, and no increased bleeding or coagulopathy was found. The respiratory parameters were significantly improved after ECMO, especially in the survivors. ECMO is also suitable for ARDS in adult burn injury.

Abstract
BACKGROUND Burn care has changed considerably. Early surgery, nutritional support, improved resuscitation and novel skin replacement techniques are now well established. The aim of the study was to establish whether changes in management have improved survival following burn injury and to determine the contributory factors leading to non-survival. METHODS This was a retrospective outcome analysis of data collected from a consecutive series of 4094 patients with burns admitted to a tertiary referral, metropolitan teaching hospital between 1972 and 1996. RESULTS The overall mortality rate was 3.6 per cent. This decreased from 5.3 per cent (1972--1980) to 3.4 per cent (1993--1996) (P = 0.076). The risk of death was increased with increasing burn size (relative risk (RR) 95.90 (95 per cent confidence interval 12.60--729.47) if more than 35 per cent of the total body surface area was burned; P < 0.001) increasing age (RR 7.32 (3.08--17.42) if aged more than 48 years; P < 0.001), inhalation injury (RR 3.61 (2.39--5.47); P < 0.001) and female sex (RR 1.82 (1.23--2.69); P = 0.003). Operative intervention (RR 0.11 (0.06--0.21); P < 0.001) and the presence of an upper limb burn (RR 0.53 (0.35--0.79); P = 0.002) decreased the risk. CONCLUSION Modern burn care has decreased the mortality rate. Increasing burn size, increasing age, inhalation injury and female sex increased, while operative intervention and an upper limb burn decreased, the risk of death.

Abstract
The study group is comprised of 234 patients (6.4%) who died out of 3680 patients treated for burn injuries during the period January 1982 to December 1997 in Kuwait. There were 112 (47.9%) males and 122 (52.1%) females and their mean age was 30 years (range 1-93) when compared with 24 years among survivors. The high mortality amongst two age groups 0-5 years (39 deaths, 16.7%) and 16-35 years (109 deaths, 46.6%) shows their vulnerability in the society. In 190 patients (81.2%) the burn injuries occurred at home. A total of 216 patients (92.3%) sustained flame burns mainly due to clothes on fire (40.6%) and cooking gas accidents (25.2%), and in 18 patients (7.7%) the burns were due to scalds. The suicidal burns occurred in 22 female and 5 male patients mainly of younger age groups. The mean percentage of burns was 71% (range 9-100%) as against 20% amongst survivors, and 195 patients (83.3%) had > or = 50% total body surface area (TBSA) burn. Four patients (1.7%) had superficial dermal burns, 94 (40.2%) had full thickness and 136 (58.1%) had mixed with full thickness burns predominance. The associated inhalation injury was diagnosed in 132 patients (56.4%). A total of 61 patients (26.1%) had either single or multiple pre-existing diseases and 51 of them sustained flame burns. The day of death varied from 1 to 103 days (mean 16 days) but 58 patients (24.8%) died within 48 hours of post burn. A total of 120 patients (51.3%) died due to septicaemia, 83 (35.5%) due to renal failure, 28 (10.2%) due to multi-organ failure, and 7 (3.0%) due to bronchopneumonia. The overall mortality rate was 6.4%, but this has significantly lowered to 4.4% (p = < 0.01) during last four years probably due to better burn care. The study thus shows that age group 0-5 and 16-35 years, domestic accidents, flame burn, inhalation injury, and pre-existing diseases are risk factors and septicaemia as the dominant cause of death in our patients.

Abstract
In order to broaden our long-term intervention efforts in elementary schools in Israel (underway since 1988) and to set priorities for further population-specific actions, we compared the pattern of burn injuries among two age groups (0-4; 5-14) of two ethnic groups of Jews and Bedouins admitted to a regional hospital between 1986 and 1995 (n = 1050). The findings indicated a significant downward trend, though somewhat nonlinear, in burn admissions among the older age groups. A relatively less favorable trend was observed for the younger age groups. Consistently across years, burn rates in the younger group of Bedouin children were the highest. For the 10-year period, a significant season by ethnic group variation in burn admissions was observed, with a peak in the spring and in the wintertime for the Jews and Bedouins, respectively. A significant trend of decrease, mostly among older children, in average lengths of hospital stay, was also evident. Yet, regardless of age group and across years, Bedouin children stayed longer in the hospital than Jewish children. The overall leading causes of injury (for 1992-1995) were hot liquids (69%), fire (17%), chemicals (9.5%) and contact (2%). In our view, there is a need to address at-risk populations through environmental, community and family-oriented interventions and to venture beyond the pathogenic factors to the investigation of the salutary factors of health under diverse life conditions.

Abstract
A retrospective study was conducted on 3341 burn patients hospitalized in a burn care center in Tehran, Iran during 1995-98. The mean age was 20.4 years, and 43.5% of patients were children under 15 years old. The mean body surface area burned was 30.6%. There were statistically significant correlations between age groups and total burn surface area (TBSA) burned with mortality rate (p<0.006). Flame was the most common etiology of burns. There was also significant correlation between age groups and causes of burns (p<0.0001). The mean hospital stay was 16.7 days. The overall mortality rate was 19.6. Most of the injuries requiring hospital admission occurred during the winter months. Parents can play an important role in prevention of burns in children who are most susceptible to burns. People with causes identified could be educated in burn prevention, through news and other media.

Abstract
We present an interesting case of the first adult reported in the United States to suffer from thermal burns, adult respiratory distress syndrome (ARDS) and to be treated with extracorporeal membrane oxygenation (ECMO) who survived. Our patient is a 26 year old male who sustained thermal burns (12% TBSA) to his face and anterior trunk and broncoscopically demonstrable inhalation injury. He was transported to our regional burn center for burn wound care and ventilatory support. The patient was treated with silver sulfadiazine 1% to his wounds which healed per primam. Because of low oxygen saturation he required increasing FIO2. The following parameters: FIO2= 1, PEEP = 17, minute ventilation of 15.1 1, peak airway pressure of 45 and mean of 27, along with chest X-rays corroborated the severity of ARDS. The patient failed volume control ventilation. A trial of pressure ventilation was attempted but the patient only reached O2 saturation in the low 80s. At this point, the decision was made to transfer the patient to a hospital capable of ECMO treatment. The patient was subsequently treated with veno venous ECMO. Six weeks later the patient was discharged from the hospital off all ventilatory support.

Abstract
A 10-bed state-of-the-art burns unit was commissioned at King Fahd Specialist Hospital, Buraidah, Al-Qassim and the first 90 cases admitted to the unit over an 18-month period were analysed. The mean age (+/-SD) was 14.9 (+/-1.5) years with a range of 6 months-55 years. Fifty-one per cent were males, 52.2 per cent were children under 12 years of age and of these 85.1 per cent were under 5 years of age. Scalds and flames accounted for 90 per cent of the burns. Domestic burns formed the majority of cases, 64 (71 per cent), and most patients were admitted within the first 24 h (76 per cent). The mean (+/-SE) of the total body surface area (TBSA) was 23 per cent (+/-2.4) with a range of 3-98 per cent. The mean hospital stay for the whole group was 16.4 days. Overall mortality was five patients (5.6 per cent) while the mortality in critical burns was 14.3 per cent. TBSA was found to be the main factor influencing mortality. This study highlights the important factors that affect the outcome in this unit. Factors that can improve the morbidity and mortality rates in patients are highlighted. The study also reveals certain patterns and etiological factors in the Qassim region. Prevention by education through a national campaign remains the keystone in reducing the incidence of burns particularly in children and the maximization of resources.

Abstract
The burns intensive care unit at IBN Sina Hospital reopened in July 1991, following the Iraqi occupation of Kuwait and the Gulf War. Epidemiology and mortality of 162 burn patients with 30 per cent and over total body surface area (TBSA) burns, treated from July 1991 to December 1994, is presented. There were 91 males and 71 females with a ratio of 1.3 to 1. The median age was 30 years (range 4 months to 93 years) and 44 per cent of the patients were 15-40 years of age. 124 (76.5 per cent) accidents occurred at home and the flame burn was the commonest involving 131 (80.9 per cent) patients. The median burn surface area was 45.5 per cent and the majority of them sustained deep burns. The hospital stay of the surviving patients ranged from 11 to 174 days (median 38 days), while the day of the death was from 1 to 134 days. Forty-six deaths represent an overall mortality rate of 28.4 per cent amongst our patients. All the patients whose Baux score was 130 and above died. Burn shock was responsible for 10 deaths, and out of them eight were not actively resuscitated due to high Baux score. Sixteen deaths occurred within 48 h postburn. Septicaemia and its related effects were responsible for the majority of the deaths.

Abstract
This study attempts to measure and quantify changes in workload and outcome in clinically ill burn patients admitted to the intensive care unit at this institution over the 11-year period 1982-92. The case notes were studied for all patients admitted to the intensive care unit, 163 cases in total, but information was incomplete in 14. Mortality over the period is compared, using Chi squared analysis with Yates correction, with mortality probability from Bull's chart relating age and body surface area of burn (1971). The trends show increasing admission rates and referral rates to ICU from other hospitals in the region, despite declining admission rates to the regional burn unit as a whole. The duration of stay for admitted patients also shows an increase, the combination of these factors suggesting an increasing workload. There has been no change in outcome over the period. The figures provide a baseline for comparison of outcome in critically ill burn patients and are an important means by which to measure future change.

Abstract
Respiratory failure is the most common cause of death after thermal injury and may be caused by inhalation injury, acute respiratory distress syndrome (ARDS) or pneumonia. ARDS is usually associated with sepsis; however, it may also occur during burn shock, especially in patients that have a delayed or inadequate fluid resuscitation. During the past 24 months, five pediatric burn patients underwent extracorporeal life support (ECLS) for respiratory failure unresponsive to optimal medical management. The mean age of the patients was 26 months (range, 8.5 to 48 months), with a mean burn size of 46% TBSA (> 95% third degree). The etiology of the respiratory failure included severe bronchospasm in a 22-month-old former premature infant with bronchopulmonary dysplasia; three patients with ARDS; and one patient with a severe inhalation injury. All five patients required greater than 56 cm H2O peak pressures and 100% FIO2 at the time of beginning ECLS. The oxygenation index (OI) ranged from 45 to 180. Three (60%) of the patients survived. In the three patients who ultimately survived, significant improvements in pulmonary and hemodynamic parameters occurred within 96 hours of ECLS. The two patients who died showed no improvement and were removed from ECLS at 10 and 11 days; both expired within hours. The patients who expired developed significant hemodynamic instability, coagulopathy, and hemorrhage from their burn wounds. The extent and degree of burn injury did not seem to alter the outcome. Indications for considering ECLS in the pediatric burn patient are unmanageable, life threatening pulmonary insufficiency in patients that undergo a relative short course of pre-ECLS ventilator support.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
A prospective study of 352 patients in an Asian National Burn Centre has been used to develop statistical predictive models for mortality and hospitalization time. The patients are largely of Asian origin. Total burn surface area (% TBSA) and presence of respiratory burns are significant independent predictors of mortality in the multiple logistic regression analysis with an accuracy of 98.3 per cent. Age is not a significant predictor of mortality in our patients. Age, % TBSA, full thickness % TBSA and respiratory burns are significant independent predictors of length of stay in hospital with a R2 value of 0.57 in the multiple linear regression analysis. There were 16 deaths, many of whom had developed multiple complications, common causes of which were sepsis, bronchopneumonia, DIVC and multiorgan failure. The final causes of death were septicaemic shock in 10 patients, extensive burns in four patients, ARDS in one patient and bleeding peptic ulcer in one patient. The development of these two mortality and morbidity predictive models is the first step in the evaluation of our results. These models have to be tested against a future set of patients. After confirmation they will aid in patient management, clinical audit, patient and family counselling. They will also serve as baseline standards for evaluation of new therapies, assist us in the allocation of resources and identifying the at-risk population for improvements in therapy.

Abstract
Antibiotic therapy in burn centres with highly specialized ICUs has reduced the mortality and morbidity in burn and trauma but, in spite of constantly improving supportive surgical and resuscitation methods, infection remains a major problem. Indeed, the clinical experience, as recorded in Europe and the USA, using different antimicrobial drugs and regimens, emphasizes a constantly evolving pattern of pathogenic microorganisms in the wound and in the rest of the patient's body, and their increasing chemoresistance. We report the preliminary results of 559 patients in a large controlled multicentre clinical study (mean age 41.4 +/- 17.8 years and burns covering a mean body surface area of 35.7%), with the collaboration of 13 of the 15 major Italian burn centres. The antibiotic treatment consisted of prophylactic administration of pefloxacin (800 mg i.v. OD for 4 days) for all patients as a first treatment while waiting for an antibiogram, and chemotherapy with teicoplanin (800 mg i.v. OD) together with netilmicin (300 mg i.m. OD) in one or more cycles. At random, half of the patients received thymostimulin (70 mg i.m. OD pro die for the first month and every other day thereafter until discharge from hospital). Of the bacterial pathogens involved in septic complications, 63.3% were Gram-positive (Staphylococcus spp. and Streptococcus spp.). The mortality rate was 15.5%. Pefloxacin chemoprophylaxis was successful in 19.4% of patients and cure or improvement was seen with combination chemotherapy in 66.7% of patients, mainly with only one treatment cycle. The incidence of mortality and sepsis was not significantly influenced by treatment with thymostimulin.

Abstract
A 1-year prospective study of 112 burn patients up to 19 years of age aimed to identify and study the determinants and mortality experiences in these burn patients and found flame burns to be the commonest, followed by scalds and electric burns. All burns other than those caused by electricity were commoner in females, more so between 15 and 19 years of age. Burns were more frequent in winter and 85 per cent of them were domestic. Nearly all burns took place during day time with a higher incidence between 06.00-09.00 h and 14.00-21.00 h. The patient fatality rate (41.1 per cent) was associated with total burn surface area. Referral time-lag was an important determinant of mortality especially in less severe burns. As would be expected, hospital stay was significantly longer in survivors.

Abstract
A 9-year retrospective review of 1,242 admissions to a tertiary burn center identified 137 patients who were intubated and ventilated for a critical airway or pulmonary problem. These patients varied in age from 2 months to 18 years with an average total body surface area (TBSA) burn of 55%. We evaluated this group for evidence of respiratory failure (ARF) as defined by the respiratory failure index (RFI) (PaO2/FIO2 < or = 300). While only 23% of admissions to the burn center were related to flame burns, these injuries accounted for 82% of children who had ARF. Forty-two percent of these intubated children had abnormalities on their admission chest x-ray and 61% of this cohort developed evidence of ARF as defined by the RFI. The development of sepsis along with ARF regardless of TBSA involvement doubles the mortality of ARF alone. Early burn wound excision and grafting is critically important to prevent the late complication of sepsis. We carefully monitor ventilator settings to insure low peak inspiratory pressures, allowing relative hypercapnia and avoiding hyperoxia. Despite an increased number of admissions and critically injured children, we have not seen an increase in morbidity and have had a 53% reduction in mortality in the last 2 years with these techniques. We believe this management offers the best outcome for the pediatric burn victim and would recommend this strategy to other centers dealing with these severely injured children.

Abstract
Analyses were made of 1368 patients who attended Kilpauk Medical College Hospital, Madras with burns between 1 May 1987 and 30 April 1988. Nine hundred and sixty-five patients were admitted, of whom 505 died. The peak age incidence was in young adults (11-30 years; 58.9 per cent of all burns). Three quarters of the patients came from the low family income group, 39.5 per cent were illiterate and 86.2 per cent of burns occurred in the home. Of those admitted 81 per cent of the injuries were flame burns; in 31.3 per cent the burn affected more than half of the body surface. Of the 505 deaths 94.8 per cent were the result of flame burns (at least 323 being caused by kerosene), and 20.4 per cent were suicide. Most of the deaths (91 per cent) occurred in the first 5 days. The urgent need for burn prevention in the Madras area is discussed.

Abstract
Between 1 August 1988 and 31 January 1992, 421 burn patients were admitted to the Burn Unit at Beilinson Medical Center. Name, age, sex, month of the year, cause of burn, area and degree of burn and duration of stay in hospital were recorded. Of these patients, 37 per cent were treated surgically and the remainder were treated conservatively. The male to female ratio was 2:1. Burns occurred most frequently in July and January; the peak average age was the first decade of life. The most frequent cause in children was scalding (domestic burns), and in adults open fires (work accidents). Patients treated by early tangential excision and skin grafting (204 operations on 157 patients) had a shorter stay in hospital than conservatively treated patients. In accordance with others, we suggest that early surgery of burn injuries decreases morbidity and mortality and leads to better aesthetic results and improved motor function. Secondly, burn injury can be prevented in children and the elderly by increasing safety measures at home, and in adults by enforcing strict safety measures at work.

Abstract
Tap water scald burns are common injuries to persons with disabilities, young children, and the elderly. A case is reported of an elderly woman with a physical and neurological handicap who while bathing received partial and full thickness (tap water) scald burns covering 20% of her total body surface area. This life-threatening injury could have been prevented with a Shower Safe, Inc. temperature-controlling water valve.
