Xiao S, Pan Z, Li H, Zhang Y, Li T, Zhang H, Ning J. The impact of inhalation injury on fluid resuscitation in major burn patients: a 10-year multicenter retrospective study. Eur J Med Res 2024; 29:283. [PMID: 38735989 PMCID: PMC11089777 DOI: 10.1186/s40001-024-01857-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2024] [Accepted: 04/23/2024] [Indexed: 05/14/2024] Open
Abstract
BACKGROUND It remains unclear whether additional fluid supplementation is necessary during the acute resuscitation period for patients with combined inhalational injury (INHI) under the guidance of the Third Military Medical University (TMMU) protocol. METHODS A 10-year multicenter, retrospective cohort study, involved patients with burns ≥ 50% total burn surface area (TBSA) was conducted. The effect of INHI, INHI severity, and tracheotomy on the fluid management in burn patients was assessed. Cumulative fluid administration, cumulative urine output, and cumulative fluid retention within 72 h were collected and systematically analyzed. RESULTS A total of 108 patients were included in the analysis, 85 with concomitant INHI and 23 with thermal burn alone. There was no significant difference in total fluid administration during the 72-h post-burn between the INHI and non-INHI groups. Although no difference in the urine output and fluid retention was shown in the first 24 h, the INHI group had a significantly lower cumulative urine output and a higher cumulative fluid retention in the 48-h and 72-h post-burn (all p < 0.05). In addition, patients with severe INHI exhibited a significantly elevated incidence of complications (Pneumonia, 47.0% vs. 11.8%, p = 0.012), (AKI, 23.5% vs. 2.9%, p = 0.037). For patients with combined INHI, neither the severity of INHI nor the presence of a tracheotomy had any significant influence on fluid management during the acute resuscitation period. CONCLUSIONS Additional fluid administration may be unnecessary in major burn patients with INHI under the guidance of the TMMU protocol.

Abstract
Acute burn injury creates a complex and multifactorial local response which may have systemic sequelae such as hypovolemia, hypothermia, cardiovascular collapse, hypercoagulability, and multi-system organ failure. Understanding the underlying pathophysiology of burn shock, the initial burn triage and assessment, calculation of fluid requirements, and the means of tailoring ongoing interventions to optimize resuscitation are critical for overcoming the wide spectrum of derangements which this condition creates. As a result, this article discusses the various key points in order to garner a greater understanding of these nuances and the optimal pathway to take when tackling these challenging issues.

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

Abstract
Prolonged resuscitation can result in burn wound conversion and other complications. Our team switched from using Parkland formula (PF) to the modified Brooke formula (BF) in January 2020. Secondary to difficult resuscitations using BF, we sought to review our data to identify factors associated with resuscitation requiring greater than predicted resuscitation with either formula, defined as 25% or more of predicted, hereafter referred to as over-resuscitation. Patients admitted to the burn unit between January 1, 2019 and August 29, 2021 for a burn injury with a percentage of total body surface area (%TBSA) ≥15% were included. Subjects <18 years, or weighing <30 kg, and those who died or had care withdrawn within 24 hours of admission were excluded. Demographics, injury information, and resuscitation information were collected. Univariate and multivariate analyses were performed to identify factors associated with over-resuscitation by either formula. P < .05 was considered significant. Sixty-four patients were included; 27 were resuscitated using BF and 37 using PF. No significant differences were observed in demographics and burn injury between the groups. Patients required a median of 3.59 ml/kg/%TBSA for BF and 3.99 ml/kg/%TBSA for PF to reach maintenance (P = .32). Over-resuscitation was more likely to occur when using BF compared to PF (59.3% vs 32.4%, P = .043). Over-resuscitation was associated with longer time to reach maintenance (OR = 1.179 [1.042-1.333], P = .009) and arrival via ground transportation (OR = 10.523 [1.171-94.597], P = .036). Future studies are warranted to identify populations in which BF under-performs and sequelae associated with prolonged resuscitation.

Abstract
Thermal energy is an essential and useful resource to humans in modern society. However, a consequence of using heat carelessly is burns. Burn injuries have various causes, such as exposure to flame, radiation, electrical, and chemical sources. In this study, we reviewed the history of burn wound care while focusing on the basic principles of burn management. Through this review, we highlight the need for careful monitoring and customization when treating burn victims at each step of wound care, as their individual needs may differ. We also propose that future research should focus on nanotechnology-based skin grafts, as this is a promising area for further improvement in wound care.

Abstract
Importance Critical burn management decisions rely on accurate percent total body surface area (%TBSA) burn estimation. Existing %TBSA burn estimation models (eg, Lund-Browder chart and rule of nines) were derived from a linear formula and a limited number of individuals a century ago and do not reflect the range of body habitus of the modern population. Objective To develop a practical %TBSA burn estimation tool that accounts for exact burn injury pattern, sex, and body habitus. Design, Setting, and Participants This population-based cohort study evaluated the efficacy of a computer vision algorithm application in processing an adult laser body scan data set. High-resolution surface anthropometry laser body scans of 3047 North American and European adults aged 18 to 65 years from the Civilian American and European Surface Anthropometry Resource data set (1998-2001) were included. Of these, 1517 participants (49.8%) were male. Race and ethnicity data were not available for analysis. Analyses were conducted in 2020. Main Outcomes and Measures The contributory %TBSA for 18 body regions in each individual. Mobile application for real-time %TBSA burn computation based on sex, habitus, and exact burn injury pattern. Results Of the 3047 individuals aged 18 to 65 years for whom body scans were available, 1517 (49.8%) were male. Wide individual variability was found in the extent to which major body regions contributed to %TBSA, especially in the torso and legs. Anterior torso %TBSA increased with increasing body habitus (mean [SD], 15.1 [0.9] to 19.1 [2.0] for male individuals; 15.1 [0.8] to 18.0 [1.7] for female individuals). This increase was attributable to increase in abdomen %TBSA (mean [SD], 5.3 [0.7] to 8.7 [1.8]) among male individuals and increase in abdomen (mean [SD], 4.6 [0.6] to 6.8 [1.7]) and pelvis (mean [SD], 1.5 [0.2] to 2.9 [0.9]) %TBSAs among female individuals. For most body regions, Lund-Browder chart and rule of nines estimates fell outside the population's measured interquartile ranges. The mobile application tested in this study, Burn Area, facilitated accurate %TBSA burn computation based on exact burn injury pattern for 10 sex and body habitus-specific models. Conclusions and Relevance Computer vision algorithm application to a large laser body scan data set may provide a practical tool that facilitates accurate %TBSA burn computation in the modern era.

Abstract
INTRODUCTION Efforts with the utilization of an Input/Output ratio (I/O ratio) are done with success for analyzing and moving forward the treatment in the resuscitation phase of the burn patient. The need for conducting this research is to apply the I/O ratio in our cohort as a helpful index for classifying the resuscitation response of the burn patients. Our prespecified hypothesis is if it matters the analysis of the I/O ratio at 8 h of fluid resuscitation period. MATERIAL AND METHOD This prospective observational study was performed in 50 patients (22 adults and 28 children) admitted in the Intensive Care of the Service of Burns in Tirana, Albania in the period January to December 2016. We calculated the I/O ratio at 8 h and the end of the 1st 24 h based on the stratification of patients according to the ratio in respective groups. In the adult population we did an analysis whereby the ratio I/O at 8 h has a relationship with the 24 h results as well as with ICU-free days. RESULTS The 24 h fluid resuscitation was done with the majority clustered in the range 2-4 ml/kg/% TBSA with fluid-weight score (ml/kg) correlated with % TBSA. After calculation of the I/O ratio at 8 h, 29 patients were assigned in over-responders (<0.166), 16 patients in the expected group(0.166-0.334), and 5 patients were assigned in under-responders (>0.334). There is a strong correlation between the I/O ratio at 8 h and the I/O ratio at 24 h and I/O ratio predict better the longer ICU-free days. CONCLUSIONS The I/O ratio is a very useful parameter not only at 12 h and 24 h but also at 8 h after burns. By classifying the patients into outcome groups that reflect not only the volume given but moreover the physiologic reactions to the resuscitation volume gotten, we were more attentive to patients in under-responders at 8 h. This parameter fulfills the criteria for better classifying patients and a better understanding of the physiology of burns.

Abstract
Fluid management is a cornerstone in the treatment of burns and, thus, many different formulas were tested for their ability to match the fluid requirements for an adequate resuscitation. Thereof, the Parkland-Baxter formula, first introduced in 1968, is still widely used since then. Though using nearly the same formula to start off, the definition of normovolemia and how to determine the volume status of burn patients has changed dramatically over years. In first instance, the invention of the transpulmonary thermodilution (TTD) enabled an early goal directed fluid therapy with acceptable invasiveness. Furthermore, the introduction of point of care ultrasound (POCUS) has triggered more individualized schemes of fluid therapy. This article explores the historical developments in the field of burn resuscitation, presenting different options to determine the fluid requirements without missing the red flags for hyper- or hypovolemia. Furthermore, the increasing rate of co-morbidities in burn patients calls for a more sophisticated fluid management adjusting the fluid therapy to the actual necessities very closely. Therefore, formulas might be used as a starting point, but further fluid therapy should be adjusted to the actual need of every single patient. Taking the developments in the field of individualized therapies in intensive care in general into account, fluid management in burn resuscitation will also be individualized in the near future.

Abstract
INTRODUCTION Traditionally, lactated Ringer's solution (LR) has been utilized for the resuscitation of thermally injured patients via the Parkland or Brooke formulas. Both of these formulas include colloid supplementation after 24 h of resuscitation. Recently, the addition of albumin within the initial resuscitation has been reported to decrease fluid creep and hourly fluids given. Our institution has previously advocated for a crystalloid-driven resuscitation. Given reports of improved outcomes with albumin, we pragmatically adjusted these practices and present our findings for doing so. METHODS Our burn registry, consisting of prospectively collected patient data, was queried for those at least 18 years of age who, between July 2017 and December 2018, sustained a thermal injury and completed a formal resuscitation (24 h). At the attending physician's discretion, rescue colloid was administered using 25% albumin for those failing to respond to traditional resuscitation (patients with sustained urine output of <0.5 mL/kg over 2-3 h, or unstable vital signs and ongoing fluid administration). We compared the total volume of the crystalloid-only and rescue colloid resuscitation fluids given to patients. We also examined the in/out fluid balances during resuscitation. Statistical analysis was performed using Stata software. RESULTS A total of 91 patients with thermal injuries were included: the median age was 40 (IQR 31-57), 73% were male, and 30 patients received rescue albumin. The percentage of total body surface area burned (%TBSA) was greater in those who received rescue albumin (40.3% vs. 34%; p = 0.047). Despite a higher %TBSA in the albumin group, the total LR given during resuscitation was not significantly different between groups (15,914.43 mL vs. 11,828.71 mL; p = 0.129) even when normalized for TBSA and weight (ml LR/kg/%TBSA: 4.31 vs. 3.66; p = 0.129. The average in/out fluid ratio for the rescue group was higher than for the crystalloid group (0.83 ± 0.05 vs. 0.59 ± 0.11; p = 0.06) and returned to normal after colloid administration. CONCLUSION Rescue albumin administration decreases the amount of fluid administered per %TBSA during resuscitation, and also increases end organ function as evidenced by increased urinary output. These effects occurred in patients who sustained larger burns and failed to respond to traditional crystalloid resuscitation. Our findings led us to modify our current protocol and a related prospective study of clinical outcomes.

Abstract
BACKGROUND The Third Military Medical University (TMMU) formula is widely utilized in the fluid resuscitation in China. However, the actual volume needs usually exceed the prediction provided by the TMMU formula in major burn patients with a high proportion of full-thickness burn wounds. METHOD This retrospective study included 149 adult major burn patients (≥40% TBSA) who were admitted to the Burn Department, Southwest Hospital from 2014 to 2020 and received appropriate fluid resuscitation by the TMMU protocol. The actual volume infused in the first 48 hours post-burn was compared to the estimation by the TMMU formula. A new fluid volume prediction formula was developed by multivariate linear regression analysis. RESULT The mean fluid requirements were 2.35 ml/kg/%TBSA and 1.75 ml/kg/%TBSA in the 1 st and 2 nd 24 hours post-burn, respectively. The TMMU formula underestimated the fluid requirement, and its prediction accuracy was 54.1% and 25.8% for the 1 st and 2 nd 24 hours, respectively. The proportion of full-thickness burn wound was found to be associated with the fluid requirements after burn. A revised multifactorial formula consisting of the burn index, body weight and inhalation injury was developed. Using the revised formula, the prediction reliability of resuscitation fluid volume improved to 65.3% and 61.1% in the 1st and 2nd 24 hours, respectively. CONCLUSION The TMMU formula showed low accuracy in predicting fluid requirements among major burn patients. A revised formula based on burn index was developed to provide better guidance for initiative fluid resuscitation for major burns by the TMMU protocol.

Obesity and the related medical, social, and economic impacts are relevant multifactorial and chronic conditions that also have a meaningful impact on outcomes following a severe injury, including burns. In addition to burn-specific difficulties, such as adequate hypermetabolic response, fluid resuscitation, and early wound coverage, obese patients also present with common comorbidities, such as arterial hypertension, diabetes mellitus, or nonalcoholic fatty liver disease. In addition, the pathophysiologic response to severe burns can be enhanced. Besides the increased morbidity and mortality compared to burn patients with normal weight, obese patients present a challenge in fluid resuscitation, perioperative management, and difficulties in wound healing. The present work is an in-depth review of the current understanding of the influence of obesity on the management and outcome of severe burns.

Is the Parkland formula still the best method for determining the fluid resuscitation volume in adults for the first 24 hours after injury? - A retrospective analysis of burn patients in Germany. Burns 2020; 47:914-921. [PMID: 33143988 DOI: 10.1016/j.burns.2020.10.001] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2020] [Revised: 09/14/2020] [Accepted: 10/02/2020] [Indexed: 12/17/2022]
Abstract
BACKGROUND R Rapid fluid resuscitation is a crucial therapy during the treatment of patients with extensive burns. In 1968, the Parkland Formula was introduced for the calculation of the estimated volume of the resuscitation fluid. Since then, different methods for the calculation of fluid resuscitation volume have been developed. We aimed to evaluate if the Parkland formula is still the most effective method for fluid resuscitation volume calculation in burn patients. METHODS In the period between January 2015 and January 2019, data from 569 patients over 16 years old with burns of more than 20% total body surface area (TBSA) and at least 15% TBSA full thickness burns were entered in the German burn registry. The patients were divided into 5 groups (0, +1, -1, +2, -2) according to the volume of the resuscitation fluid they received. Group 0 patients received the amount of fluid calculated according to the Parkland formula (n = 83). The 4 other groups received reduced (-1, -2) or increased (+1, +2) fluid volumes in comparison to the value obtained by the Parkland formula. RESULTS Patients in Group 0 presented a significantly lower mortality in the first week (4.5%) compared to groups -2 (16.7%) and group +2 (19.5%) (p = 0.021). Furthermore, the mean number of operations in group +2 (5.81) was higher than in group -2 (3.81). Surviving patients from group +2 presented a longer hospital stay (68.1 days) compared to the other groups. Additionally, the logistic regression analysis showed a higher survival of patients in groups -2 and -1 (regression coefficients -0.11 and -0.086; Odds Ratio 0.896 and 0.918; 95% Confidence Interval (CI) 0,411-1.951 and 0.42-2.004). CONCLUSION In this retrospective study, register based analysis a restrictive fluid regime was associated with a higher survival compared to the liberal Parkland guided fluid regime.

Abstract
BACKGROUND Gastrointestinal (GI) dysmotility impedes nutrient delivery in critically ill patients with major burns. We aimed to quantify the incidence, timing, and factors associated with GI dysmotility and subsequent nutrition delivery. METHODS A 10-year retrospective observational study included mechanically ventilated, adult, critically ill patients with ≥15% total body surface area (TBSA) burns receiving nutrition support. Patients with a single gastric residual volume ≥250 mL were categorized as having GI dysmotility. Daily medical and nutrition data were extracted for ≤14 days in the intensive care unit (ICU). Data are mean (SD) or median (interquartile range). Factors associated with GI dysmotility and the effect on nutrition and clinical outcomes were assessed. RESULTS Fifty-nine patients were eligible; 51% (n = 30) with GI dysmotility and 49% (n = 29) without. Baseline characteristics (dysmotility vs no dysmotility) were age (48 [33-60] vs 34 [26-46] years); Acute Physiology and Chronic Health Evaluation II score (16 [12-17] vs 13 [10-16]); sex ([men] 80% vs 86%); and TBSA (49% [35%-59%] vs 38% [26%-55%]). Older age was associated with increased probability of dysmotility (P = .049). GI dysmotility occurred 32 (19-63) hours after ICU admission but was not associated with reduced nutrient delivery. Postpyloric tube insertions were attempted in 83% (n = 25) of patients, with 72% (n = 18) being successful. Postpyloric feeding achieved higher nutrition adequacy than gastric feeding (energy: 82% [95% CI, 70-94] vs 68% [95% CI, 63-74], P = .036; protein: 75% [95% CI, 65-86] vs 61% [95% CI, 56-65], P = .009). CONCLUSION GI dysmotility occurs early in critically ill burn patients, and postpyloric feeding improves nutrition delivery.

Abstract
Orbital compartment syndrome (OCS) is a rare but devastating complication of over-resuscitation in burn patients that may lead to permanent visual loss. The purpose of this study was to 1) present a series of burn patients with OCS and 2) survey practice patterns of monitoring intra-ocular pressure (IOP) during burn resuscitation. Cases of OCS at two American Burn Association (ABA)-verified burn centers were retrospectively reviewed. Patients were included if they 1) required lateral canthotomy/cantholysis for elevated IOPs or 2) developed blindness on admission unrelated to any other ocular pathology. Data were collected on demographics, burn characteristics, fluid administration, ophthalmologic findings, and complications. An eight-item electronic survey was distributed by email through the ABA to all physician members. Twelve patients with OCS were identified, with a mean age of 47.8 ± 12.4 years and TBSA of 63.7 ± 18.6%. Mean fluid resuscitation at 24 hours was 4.9 ± 1.6 ml/kg/%TBSA or 0.29 ± 0.06 liter/kg. Eight patients underwent canthotomy/cantholysis for OCS, whereas four were later found to have visual loss. A total of 83 (14%) ABA physicians responded to the survey. IOP was routinely measured by 23% of respondents during acute burn resuscitation. OCS appears to have developed despite a relatively low 24-hour ml/kg/% burn resuscitation volume, but with a relatively higher cumulative (liter/kg) fluid volume. Their survey found that monitoring of IOP during burn resuscitation is not routinely performed by the majority of providers. Taken together, the present study suggests clinical guidelines to recognize this complication of over-resuscitation.

Lactate and lactate clearance in critically burned patients: usefulness and limitations as a resuscitation guide and as a prognostic factor. Burns 2020; 46:1839-1847. [PMID: 32653255 DOI: 10.1016/j.burns.2020.06.003] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2019] [Revised: 05/30/2020] [Accepted: 06/08/2020] [Indexed: 11/22/2022]
Abstract
OBJECTIVE Lactate levels to guide resuscitation in critically burned patients are controversial. The purpose of our study was to determine whether absolute lactate values or lower lactate clearance predict mortality, and whether these are useful tools in the resuscitation phase. METHODS We conducted a prospective, unicentric, observational study of a cohort of 214 burn patients admitted in the Burn Intensive Care Unit. We collected demographic and laboratory data, complications, absolute lactate levels and lactate clearance every 8 h since admission to 72 h. In critical patients we monitored hemodynamic parameters with transpulmonary thermodilution. We used Student's t-test or nonparametric tests, mixed models and Pearson and Spearman methods, Fisher's exact and chi-squared test. RESULTS Of the 214 patients, 76.6% were male, mean age were 46 ± 15 years and 23.0 ± 19.5% of Total Basal Surface Area (TBSA) burned. Initial mean absolute levels of lactate were 2.02 ± 1.62 mmol/L in survivors vs. 4.05 ± 3.90 mmol/L in nonsurvivors. Initial elevated lactate levels increased mortality (p < .001), length of ICU stay, mechanical ventilation and shock. In the subgroup of burned TBSA < 20%, lowering the lactate cut-off point from 2.0 to 1.8 mmol/L improved the mortality prediction (OR:9.3). We found no relationship between lactate clearance in the first 24 h and mortality. In more severe patients (> 20% TBSA burned and initial lactate levels > 2), a good correlation was found between lactate and cardiac index; but not with intrathoracic blood volume index (ITBVI). Patients with low ITBVI preload (< 600 mL/m2) did not show significant differences in lactate clearance compared with those with ITBVI > 600. CONCLUSIONS Initial elevated lactate levels are a factor of poor prognosis and the cut-off point that best predicts mortality should be adjusted in the patients with TBSA burned < 20%. The global clearance of lactate in the first 24 h, unlike what occurs in other injuries, does not correlate with mortality. Monitoring lactate can ensure adequate peripheral perfusion during resuscitation with lower than normal fluid preload values.

Abstract
Thermal burn injury methodologies are inconsistently described within the current literature. To permit the advancement of new treatments there is an urgent need for the development and standardisation of an acute rat model. We describe a rat thermal burn model that involves: anaesthesia, chronic catheterisation, skin preparation, baseline hemodynamic and physiological monitoring, and a quantifiable method to reproduce a severe full-thickness burns injury affecting ∼30% percent of the total body surface area (%TBSA). Following a 15 min post-burn period, treatment commences with an acute monitoring phase lasting up to 8 h, which can be modified according to individual protocols. This model reflects the clinical continuum-of-care from point-of-injury, a 15 min ambulance response time, a 60 min prehospital phase and hospital treatment monitoring phase. The model is validated with histological evidence of full-thickness injury, evidence of the hypermetabolic response (K+, Base Excess, lactate) and changes in complete blood counts. •It has been 50 years since Walker and Mason published their widely popular "A Standard Animal Burn Model".•The model, however, lacks quantifiable methodology for the assessment of burn thickness, surface area burnt and physiological status.•We present a new standardised method for evaluation of drug and interventional therapies that mimic the clinical scenario including ambulance response, pre-hospital and hospital phases after burn.

Abstract
Critical appraisal of outcomes after burn shock resuscitation with albumin has previously been restricted to small relatively old randomized trials, some with high risk of bias. Extensive recent data from nonrandomized studies assessing the use of albumin can potentially reduce bias and add precision. The objective of this meta-analysis was to determine the effect of burn shock resuscitation with albumin on mortality and morbidity in adult patients. Randomized and nonrandomized controlled clinical studies evaluating mortality and morbidity in adult patients receiving albumin for burn shock resuscitation were identified by multiple methods, including computer database searches and examination of journal contents and reference lists. Extracted data were quantitatively combined by random-effects meta-analysis. Four randomized and four nonrandomized studies with 688 total adult patients were included. Treatment effects did not differ significantly between the included randomized and nonrandomized studies. Albumin infusion during the first 24 hours showed no significant overall effect on mortality. However, significant statistical heterogeneity was present, which could be abolished by excluding two studies at high risk of bias. After those exclusions, albumin infusion was associated with reduced mortality. The pooled odds ratio was 0.34 with a 95% confidence interval of 0.19 to 0.58 (P < .001). Albumin administration was also accompanied by decreased occurrence of compartment syndrome (pooled odds ratio, 0.19; 95% confidence interval, 0.07–0.50; P < .001). This meta-analysis suggests that albumin can improve outcomes of burn shock resuscitation. However, the scope and quality of current evidence are limited, and additional trials are needed.

Abstract
Objective Fluid creep in patients recovering from acute burns still exists, despite the use of a more treatment conservative approach. Most of our severe burn patients develop fluid overload and body weight increase after acute fluid resuscitation. How to quickly return patients to their pre-injury body weight is an important issue. Methods Right after acute fluid resuscitation, we applied a “total fluid requirement” volume (usually 1/2 to 2/3 of initial 24 hour volume) and strictly monitored patients' hourly urine (between 0.5-1 ml/kg/hr). Patients' responses (body weight, enteric feeding amount, pulmonary condition, etc.) were also closely monitored and frequent adjustments of fluid volume administration were performed simultaneously. Results Most patients regained their pre-injury body weight within 2-3 weeks. Enteric feeding also improved markedly. No patients had severe oedema-related complications. Conclusions Stricter fluid administration after acute burn fluid resuscitation is advised for allowing patients to reduce body weight to their pre-injury weight or at least close to it. We use pre-injury body weight, enteric feeding and urine output as our guides. (Hong Kong j.emerg.med. 2014;21:222-229)

Abstract
Management of severe burn injury (SBI) requires prompt, complex, and aggressive care. Despite major advances in the management of SBI-including patient-targeted resuscitation, management of inhalation injuries, specific nutritional support, enhanced wound therapy, and infection control-the consequences of SBI often result in complex, multiorgan metabolic changes. Consensus guidelines and clinical evidence regarding specific management of small animal burn patients are lacking. This article aims to review updated therapeutic consideration for the systemic and local management of SBI that are proven effective to optimize outcomes in human burn patients and may translate to small animal patients.

Abstract
More than 4 decades after the creation of the Brooke and Parkland formulas, burn practitioners still argue about which formula is the best. So it is no surprise that there is no consensus about how to resuscitate a thermally injured patient with a significant comorbidity such as heart failure or cirrhosis or how to resuscitate a patient after an electrical or inhalation injury or a patient whose resuscitation is complicated by renal failure. All of these scenarios share a common theme in that the standard rule book does not apply. All will require highly individualized resuscitations.

Abstract
OBJECTIVE To determine whether restrictive fluid resuscitation results in increased rates of acute kidney injury (AKI) or infectious complications. BACKGROUND Studies demonstrate that patients often receive volumes in excess of those predicted by the Parkland equation, with potentially detrimental sequelae. However, the consequences of under-resuscitation are not well-studied. METHODS Data were collected from a multicenter prospective cohort study. Adults with greater than 20% total burned surface area injury were divided into 3 groups on the basis of the pattern of resuscitation in the first 24 hours: volumes less than (restrictive), equal to, or greater than (excessive) standard resuscitation (4 to 6 cc/kg/% total burned surface area). Multivariable regression analysis was employed to determine the effect of fluid group on AKI, burn wound infections (BWIs), and pneumonia. RESULTS Among 330 patients, 33% received restrictive volumes, 39% received standard resuscitation volumes, and 28% received excessive volumes. The standard and excessive groups had higher mean baseline APACHE scores (24.2 vs 16, P < 0.05 and 22.3 vs 16, P < 0.05) than the restrictive group, but were similar in other characteristics. After adjustment for confounders, restrictive resuscitation was associated with greater probability of AKI [odds ratio (OR) 3.25, 95% confidence interval (95% CI) 1.18-8.94]. No difference in the probability of BWI or pneumonia among groups was found (BWI: restrictive vs standard OR 0.74, 95% CI 0.39-1.40, excessive vs standard OR 1.40, 95% CI 0.75-2.60, pneumonia: restrictive vs standard, OR 0.52, 95% CI 0.26-1.05; excessive vs standard, OR 1.12, 95% CI 0.58-2.14). CONCLUSIONS Restrictive resuscitation is associated with increased AKI, without changes in infectious complications.

Abstract
This article reviews the pathophysiology of large burn injury and the extreme fluid shifts that occur in the hours and days after this event. The authors focus on acute fluid management, monitoring of hemodynamic status, and end points of resuscitation. Understanding the need and causes for fluid resuscitation after burn injury helps the clinician develop an effective plan to balance the competing goals of normalized tissue perfusion and limited tissue edema. Thoughtful, individualized treatment is the best answer and the most effective compromise.

Abstract
Background Burn injury and its subsequent multisystem effects are commonly encountered by acute care practitioners. Resuscitation is the major component of initial burn care and must be managed to restore and preserve vital organ function. Later complications of burn injury are dominated by infection. Burn centers are often called to manage problems related to thermal injury, including lightning and electrical injuries. Methods A selected review is provided of key management concepts as well as of recent reports published by the American Burn Association. Results The burn-injured patient is easily and frequently over resuscitated, with ensuing complications that include delayed wound healing and respiratory compromise. A feedback protocol designed to limit the occurrence of excessive resuscitation has been proposed, but no new “gold standard” for resuscitation has replaced the venerated Parkland formula. While new medical therapies have been proposed for patients sustaining inhalation injury, a paradigm-shifting standard of medical therapy has not emerged. Renal failure as a specific contributor to adverse outcome in burns has been reinforced by recent data. Of special problems addressed in burn centers, electrical injuries pose multisystem physiologic challenges and do not fit typical scoring systems. Conclusion Recent reports emphasize the dangers of over resuscitation in the setting of burn injury. No new medical therapy for inhalation injury has been generally adopted, but new standards for description of burn-related infections have been presented. The value of the burn center in care of the problems of electrical exposure, both manmade and natural, is demonstrated in recent reports.

Abstract
INTRODUCTION Resuscitation from burn shock using fresh frozen plasma (FFP) has been described. Critics of FFP resuscitation cite the development of transfusion related acute lung injury (TRALI) as a deterrent to its use. This study examines the occurrence of TRALI with FFP resuscitation of critically ill burned patients. METHODS A retrospective chart review was conducted of severely burned patients who received FFP resuscitation. Data points included age, TBSA, TBSA full thickness, presence of alternate etiologies of acute lung injury, total FFP administered, and signs and symptoms of TRALI as defined per the Canadian Blood Services Consensus Conference. RESULTS Eighty-three patients met the definition of severe burn and received FFP resuscitation. Of those, 65 met exclusion criteria. Eighteen patients were left for analysis with only one found to have signs and symptoms of TRALI. That patient suffered a 53.5% TBSA burn, received a total of 6228ml FFP, had no competing etiologies of ALI, and was diagnosed with TRALI within 6h of completing the FFP transfusion. CONCLUSION The possible occurrence of TRALI in burn patients receiving FFP resuscitation should be weighed against the reported benefits of such a resuscitation strategy.

Abstract
INTRODUCTION Initial therapy of severe burns in specialized burn trauma centers is a challenging task faced by the treating multi-professional and interdisciplinary team. A lack of consistent operating procedures and varying structural conditions was recently demonstrated in preliminary data of our group. These results raised the question on how specific treatment measures in acute burn care are met in the absence of standardized guidelines. MATERIAL AND METHODS A specific questionnaire containing 57 multiple-choice questions was sent to all 22 major burn centers in Germany, Austria and Switzerland. The survey included standards of airway management and ventilation, fluid management and circulation, body temperature monitoring and management, topical burn wound treatment and a microbiological surveillance. Additionally, the distribution of standardized course systems was covered. RESULTS 17 out of 22 questionnaires (77%) were returned completed. Regarding volume resuscitation, results showed a similar approach in estimating initial fluid while discrepancies persisted in the use of colloidal fluid and human albumin. Elective tracheostomy and the need for bronchoscopy with suspected inhalation injury were the most controversial issues revealed by the survey. Topical treatment of burned body surface also followed different principles regarding the use of synthetic epidermal skin substitutes or enzymatic wound debridement. Less discrepancy was found in basic diagnostic measures, body temperature management, estimation of the extent of burns and microbiological surveillance. CONCLUSION While many burn-related issues are clearly not questionable and managed in a similar way in most participating facilities, we were able to show that the most contentious issues in burn trauma management involve initial volume resuscitation, management of inhalation trauma and topical burn wound treatment. Further research is required to address these topics and evaluate a potential superiority of a regime in order to increase the level of evidence.

Abstract
Background Impact of early systemic hemodynamic alterations and fluid resuscitation on outcome in the modern burn care remains controversial. We investigate the association between acute-phase systemic hemodynamics, timing of fluid resuscitation and outcome in critically ill burn patients. Methods Retrospective, single-center cohort study was conducted in a university hospital. Forty critically ill burn patients with total body surface area (TBSA) burn-injured >20 % with invasive blood pressure and cardiac output monitoring (transpulmonary thermodilution technique) within 8 h from trauma were included. We retrospectively examined hemodynamic variables during the first 24 h following admission, and their association with 90-day mortality. Results The median (interquartile range 25th–75th percentile) TBSA, Simplified Acute Physiology Score II (SAPS II) and Abbreviated Burn Severity Index of the study population were 41 (29–56), 31 (23–50) and 9 (7–11) %, respectively. 90-Day mortality was 42 %. There was no statistical difference between the median pre-hospital and 24-h administered fluid volume in survivors and non-survivors. On admission, stroke volume (SV), cardiac index (CI), oxygen delivery index and mean arterial pressure (MAP) were significantly lower in patients who died despite similar fluid resuscitation volume. ROC curves comparing the ability of initial SV, CI, MAP and lactate to discriminate 90-day mortality gave areas under curves of, respectively, 0.89 (CI 0.77–1), 0.77 (CI 0.58–0.95), 0.73 (CI 0.53–0.93) and 0.78 (CI 0.63–0.92); (p value <0.05 for all). In multivariate analysis, SAPS II and initial SV were independently associated with 90-day mortality (best cutoff value for SV was 27 mL, sensitivity 92 %, specificity 69 %). During 24 h, no interaction was found between time and outcome regarding macrocirculatory parameters changes. Hemodynamic parameters improved during the first 24-h resuscitation in all patients but patients who died had lower SV and CI on admission, which remained through the first 24 h. Conclusion Low initial SV and CI were associated with poor outcome in critically ill burn patients. Very early hemodynamic monitoring may in help detecting under-resuscitated patients. Future prospective interventional studies should explore the impact of early goal-directed therapy in these specific patients.

Abstract
Fluid creep is the term applied to a burn resuscitation, which requires more fluid than predicted by standard formulas. Fluid creep is common today and is linked to several serious edema-related complications. Increased fluid requirements may accompany the appropriate resuscitation of massive injuries but dangerous fluid creep is also caused by overly permissive fluid infusion and the lack of colloid supplementation. Several strategies for recognizing and treating fluid creep are presented.

J ROY ARMY MED CORPS 2016; 163:58-64. [PMID: 27278968 DOI: 10.1136/jramc-2015-000438] [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: 03/09/2015] [Revised: 02/29/2016] [Accepted: 03/03/2016] [Indexed: 11/04/2022]
Abstract
AIMS While the epidemiology of amputations in patients with burns has been investigated previously, the effect of an amputation on burn size and its impact on fluid management have not been considered in the literature. Fluid resuscitation volumes are based on the percentage of the total body surface area (%TBSA) burned calculated during the primary survey. There is currently no consensus as to whether the fluid volumes should be recalculated after an amputation to compensate for the new body surface area. The aim of this study was to model the impact of an amputation on burn size and predicted fluid requirement. METHODS A retrospective search was performed of the database at the Queen Elizabeth Hospital Birmingham Regional Burns Centre to identify all patients who had required an early amputation as a result of their burn injury. The search identified 10 patients over a 3-year period. Burn injuries were then mapped using 3D modelling software. BurnCase3D is a computer program that allows accurate plotting of burn injuries on a digital mannequin adjusted for height and weight. Theoretical fluid requirements were then calculated using the Parkland formula for the first 24 h, and Herndon formula for the second 24 h, taking into consideration the effects of the amputation on residual burn size. RESULTS AND CONCLUSIONS This study demonstrated that amputation can have an unpredictable effect on burn size that results in a significant deviation from predicted fluid resuscitation volumes. This discrepancy in fluid estimation may cause iatrogenic complications due to over-resuscitation in burn-injured casualties. Combining a more accurate estimation of postamputation burn size with goal-directed fluid therapy during the resuscitation phase should enable burn care teams to optimise patient outcomes.

First resuscitation of critical burn patients: progresses and problems. Med Intensiva 2016; 40:118-24.

Abstract
Currently, the aim of the resuscitation of burn patients is to maintain end-organ perfusion with fluid intake as minimal as possible. To avoid excess intake, we can improve the estimation using computer methods. Parkland and Brooke are the commonly used formulas, and recently, a new, an easy formula is been used, i.e. the 'Rule of TEN'. Fluid resuscitation should be titrated to maintain the urine output of approximately 30-35 mL/h for an average-sized adult. The most commonly used fluids are crystalloid, but the phenomenon of creep flow has renewed interest in albumin. In severely burn patients, monitoring with transpulmonary thermodilution together with lactate, ScvO2 and intraabdominal pressures is a good option. Nurse-driven protocols or computer-based resuscitation algorithms reduce the dependence on clinical decision making and decrease fluid resuscitation intake. High-dose vitamin C, propranolol, the avoidance of excessive use of morphine and mechanical ventilation are other useful resources.

Abstract
Anastomotic leak continues to be a dreaded complication after colorectal surgery, especially in the low colorectal or coloanal anastomosis. However, there has been no consensus on the management of the low colorectal anastomotic leak. Currently operative procedures are reserved for patients with frank purulent or feculent peritonitis and unstable vital signs, and vary from simple fecal diversion with drainage to resection of the anastomosis and closure of the rectal stump with end colostomy (Hartmann’s procedure). However, if the patient is stable, and the leak is identified days or even weeks postoperatively, less aggressive therapeutic measures may result in healing of the leak and salvage of the anastomosis. Advances in diagnosis and treatment of pelvic collections with percutaneous treatments, and newer methods of endoscopic therapies for the acutely leaking anastomosis, such as use of the endosponge, stents or clips, have greatly reduced the need for surgical intervention in selected cases. Diverting ileostomy, if not already in place, may be considered to reduce fecal contamination. For subclinical leaks or those that persist after the initial surgery, endoluminal approaches such as injection of fibrin sealant, use of endoscopic clips, or transanal closure of the very low anastomosis may be utilized. These newer techniques have variable success rates and must be individualized to the patient, with the goal of treatment being restoration of gastrointestinal continuity and healing of the anastomosis. A review of the treatment of low colorectal anastomotic leaks is presented.

Abstract
Burn patients provide numerous challenges to the anesthesiologist. It is important to understand the multiple physiologic disruptions that follow a burn injury as well as the alterations in pharmacokinetics and pharmacodynamics of commonly used anesthetics. Thought must be given to surgery during initial fluid resuscitation and the airway challenges many of these patients present. Finally, the central role of pain management through all phases of care is a constant concern.

Abstract
A survey of members of the International Society of Burn Injuries (ISBI) and the American Burn Association (ABA) indicated that although there was difference in burn resuscitation protocols, they all fulfilled their functions. This study presents the findings of the same survey replicated in Africa, the only continent not included in the original survey. One hundred and eight responses were received. The mean annual number of admissions per unit was ninety-eight. Fluid resuscitation was usually initiated with total body surface area burns of either more than ten or more than fifteen percent. Twenty-six respondents made use of enteral resuscitation. The preferred resuscitation formula was the Parkland formula, and Ringer's Lactate was the favoured intravenous fluid. Despite satisfaction with the formula, many respondents believed that patients received volumes that differed from that predicted. Urine output was the principle guide to adequate resuscitation, with only twenty-one using the evolving clinical picture and thirty using invasive monitoring methods. Only fifty-one respondents replied to the question relating to the method of adjusting resuscitation. While colloids are not available in many parts of the African continent on account of cost, one might infer than African burn surgeons make better use of enteral resuscitation.

Abstract
INTRODUCTION Accurate estimation of burn size is of critical importance, as it is incorporated in every resuscitation formula. The aim of this study was to investigate total burn surface area (TBSA) accuracy among burn specialists, evaluate the potential impact of incorrect evaluation on variations of resultant fluid resuscitation volumes and to discuss future possibilities to estimate or measure TBSA more precisely. METHODS In a poll during two international burn meetings in 2010 and 2011 demonstrating three pictures of patients with different burn wound patterns and sizes we asked participants to estimate the total surface area burned in percentages. We then calculated resultant fluid volume differences based on established resuscitation formulas. RESULTS In the polled 80 participants, the estimations for three patients demonstrated the following differences (DIF=MAX-MIN): for patient 1, 2 and 3 they were 22.5 (25-2.5), 16.5 (20-3.5) and 31.5 (40-8.5) %TBSA, respectively. Based on these differences we calculated the volume differences for patients 1,2 and 3, which were 1080ml (Cincinnati Formula), 5280ml (Parkland Formula) and 2016ml (Cincinnati Formula), respectively. CONCLUSIONS The analysis showed high deviations of total body surface area among participants, also resulting in large variations of initial fluid resuscitation volumes. One option to address estimation variances is to perform more accurate assessments; also incorporating new technologies aiding to improve the quality of body surface estimations and related decisions.

Abstract
Burn and disuse results in metabolic and bone changes associated with substantial and sustained bone loss. Such loss can lead to an increased fracture incidence and osteopenia. We studied the independent effects of burn and disuse on bone morphology, composition and strength, and microstructure of the bone alterations 14days after injury. Sprague-Dawley rats were randomized into four groups: Sham/Ambulatory (SA), Burn/Ambulatory (BA), Sham/Hindlimb Unloaded (SH) and Burn/Hindlimb Unloaded (BH). Burn groups received a 40% total body surface area full-thickness scald burn. Disuse by hindlimb unloading was initiated immediately following injury. Bone turnover was determined in plasma and urine. Femur biomechanical parameters were measured by three-point bending tests and bone microarchitecture was determined by micro-computed tomography (uCT). On day 14, a significant reduction in body mass was observed as a result of burn, disuse and a combination of both. In terms of bone health, disuse alone and in combination affected femur weight, length and bone mineral content. Bending failure energy, an index of femur strength, was significantly reduced in all groups and maximum bending stress was lower when burn and disuse were combined. Osteocalcin was reduced in BA compared to the other groups, indicating influence of burn. The reductions observed in femur weight, BMC, biomechanical parameters and indices of bone formation are primarily responses to the combination of burn and disuse. These results offer insight into bone degradation following severe injury and disuse.

Abstract
BACKGROUND Burn demographics, prevention and care have changed considerably since the 1970s. The objectives were to 1) identify new and confirm previously described changes, 2) make comparisons to the American Burn Association National Burn Repository, 3) determine when the administration of fluids in excess of the Baxter formula began and to identify potential causes, and 4) model mortality over time, during a 36-year period (1974-2009) at the Harborview Burn Center in Seattle, WA, USA. METHODS AND FINDINGS 14,266 consecutive admissions were analyzed in five-year periods and many parameters compared to the National Burn Repository. Fluid resuscitation was compared in five-year periods from 1974 to 2009. Mortality was modeled with the rBaux model. Many changes are highlighted at the end of the manuscript including 1) the large increase in numbers of total and short-stay admissions, 2) the decline in numbers of large burn injuries, 3) that unadjusted case fatality declined to the mid-1980s but has changed little during the past two decades, 4) that race/ethnicity and payer status disparity exists, and 5) that the trajectory to death changed with fewer deaths occurring after seven days post-injury. Administration of fluids in excess of the Baxter formula during resuscitation of uncomplicated injuries was evident at least by the early 1990s and has continued to the present; the cause is likely multifactorial but pre-hospital fluids, prophylactic tracheal intubation and opioids may be involved. CONCLUSIONS 1) The dramatic changes include the rise in short-stay admissions; as a result, the model of burn care practiced since the 1970s is still required but is no longer sufficient. 2) Fluid administration in excess of the Baxter formula with uncomplicated injuries began at least two decades ago. 3) Unadjusted case fatality declined to ∼6% in the mid-1980s and changed little since then. The rBaux mortality model is quite accurate.

Abstract
BACKGROUND One of the major determinants for survival of severely burned patients is appropriate fluid resuscitation. At present, fluid resuscitation is calculated based on body weight or body surface area, burn size, and urinary output. However, recent evidence suggests that fluid calculation is inadequate and that over- and under-resuscitations are associated with increased morbidity and mortality. We hypothesize that optimizing fluid administration during the critical initial phase using a transcardiopulmonary thermodilution monitoring device (pulse contour cardiac output [PiCCO]; Pulsion Medical Systems, Munich, Germany) would have beneficial effects on the outcome of burned patients. METHODS A cohort of 76 severely burned pediatric patients with burns over 30% of the total body surface area who received adjusted fluid resuscitation using the PiCCO system were compared with 76 conventionally monitored patients (C). Clinical hemodynamic measurements, organ function (DENVER2 score), and biomarkers were recorded prospectively for the first 20d after burn injury. RESULTS Both cohorts were similar in demographic and injury characteristics. Patients in the PiCCO group received significantly less fluids (P<0.05) with similar urinary output, resulting in a significantly lower positive fluid balance (P<0.05). The central venous pressure in the PiCCO group was maintained in a more controlled range (P<0.05), associated with a significantly lower heart rate and significantly lower incidence of cardiac and renal failure (P<0.05). CONCLUSIONS Fluid resuscitation guided by transcardiopulmonary thermodilution during hospitalization represents an effective adjunct and is associated with beneficial effects on postburn morbidity.

Abstract
Fluid resuscitation following burn injury must support organ perfusion with the least amount of fluid necessary and the least physiological cost. Under resuscitation may lead to organ failure and death. With adoption of weight and injury size-based formulas for resuscitation, multiple organ dysfunction and inadequate resuscitation have become uncommon. Instead, administration of fluid volumes well in excess of historic guidelines has been reported. A number of strategies including greater use of colloids and vasoactive drugs are now under investigation to optimize preservation of end organ function while avoiding complications which can include respiratory failure and compartment syndromes. Adjuncts to resuscitation, such as antioxidants, are also being investigated along with parameters beyond urine output and vital signs to identify endpoints of therapy. Here we briefly review the state-of-the-art and provide a sample of protocols now under investigation in North American burn centers.

Abstract
Since the early 1900s, the scope of burn resuscitation has evolved dramatically. Due to various advances in pre-hospital care and training, under-resuscitation of patients with severe burns is now relatively uncommon. Over-resuscitation, otherwise known as “fluid creep”, has emerged as one of the most important problems during the initial phases of burn care over the past decade. To avoid the complications of over-resuscitation, careful hourly titration of fluid rates based on compilation of various clinical end points by a bedside provider is vital. The aim of this review is to provide a practical approach to the resuscitation of severely burned patients.

Increased B-type natriuretic peptide and decreased proteinuria might reflect decreased capillary leakage and is associated with a better outcome in patients with severe burns. Crit Care 2011; 15:R161. [PMID: 21722363 PMCID: PMC3387595 DOI: 10.1186/cc10297] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2010] [Revised: 04/18/2011] [Accepted: 07/01/2011] [Indexed: 11/10/2022] Open
Abstract
Introduction It is difficult to adjust fluid balance adequately in patients with severe burns due to various physical changes. B-type natriuretic peptide (BNP) is emerging as a potential marker of hydration state. Proteinuria is used as a predictor of outcome in severe illness and might correlate to systemic capillary leakage. This study investigates whether combining BNP and proteinuria can be used as a guide for individualized resuscitation and as a predictor of outcome in patients with severe burns. Methods From 2006 to 2009, 38 consecutive patients (age 47 ± 15 years, 74% male) with severe burns were included and followed for 20 days. All had normal kidney function at admission. BNP and proteinuria were routinely measured. Ordered and actually administered fluid resuscitation volumes were recorded. The Sequential Organ Failure Assessment (SOFA) score was used as the measure of outcome. Results BNP increased during follow-up, reaching a plateau level at Day 3. Based on median BNP levels at Day 3, patients were divided into those with low BNP and those with high BNP levels. Both groups had comparable initial SOFA scores. Patients with high BNP received less fluid from Days 3 to 10. Furthermore, patients with a high BNP at Day 3 had less morbidity, reflected by lower SOFA scores on the following days. To minimize effects of biological variability, proteinuria on Days 1 and 2 was averaged. By dividing the patients based on median BNP at Day 3 and median proteinuria, patients with high BNP and low proteinuria had significantly lower SOFA scores during the entire follow-up period compared to those patients with low BNP and high proteinuria. Conclusions Patients with higher BNP levels received less fluid. This might be explained by a lower capillary leakage in these patients, resulting in more intravascular fluid and consequently an increase in BNP. In combination with low proteinuria, possibly reflecting minimal systemic capillary leakage, a high BNP level was associated with a better outcome. BNP and proteinuria have prognostic potential in severely burned patients and may be used to adjust individual resuscitation.

Abstract
Fluid resuscitation management can influence inflammatory response after burn injury. The aim of this study was to analyze the effects of two fluid resuscitation methods on the cytokine production and on the expression of the leukocyte surface markers. Thirty patients were included in this prospective randomized study with burn injury affecting more than 20% of the body surface area. Fluid resuscitation was guided by hourly urine output (HUO, n = 15) or by intrathoracic blood volume index (ITBVI, n = 15). Blood samples were taken on admission and on the next five consecutive mornings. Concentrations of interleukin (IL)-1beta, IL-6, IL-8, IL-10, IL-12p70, and tumor necrosis factor-alpha were measured in phorbol myristate acetate-stimulated and -nonstimulated samples. Leukocyte surface marker expressions (CD11a, CD11b, CD14, CD18, CD49d, and CD97) were also determined. In the ITBVI group, IL-6 levels on days 2 to 3 and IL-6/IL-10 ratios on days 2 to 3, and the IL-8/IL-10 ratios on days 3 to 5 were significantly higher than those in HUO group (P < .05). In the HUO group, IL-10 levels were significantly higher (P < .05) on days 4 and 5. Granulocyte CD11a levels on day 2, CD11b levels on days 4 to 6, lymphocyte CD11a on days 5 to 6, CD11b on days 3 to 6, CD49d on days 2 to 6, CD97 on day 6, monocyte CD11a, CD11b, CD18 levels on days 4 to 6, and CD14 levels on days 3 to 5 were significantly higher in the HUO group (P < .05). Our study suggests that ITBVI-guided fluid resuscitation of burned patients suppresses the shift toward anti-inflammatory imbalance and the expression of leukocyte surface markers more than HUO-guided resuscitation.

Abstract
BACKGROUND The Alfred pre-hospital fluid isotonic crystalloid resuscitation formula for major burns (body weight (kg)×%TBSA burnt=mls in the first 2 h) was adopted by Ambulance Victoria in 2007 for the early and consistent correction of fluid deficit in major burns patients. The aim of this study was to evaluate the associated change in pre-hospital fluid administration. METHODS A retrospective explicit chart review of patient records was conducted of all patients with major burns presenting to The Alfred Emergency & Trauma Centre over a 10 year period. Patient demographics, fluid resuscitation and outcomes in the period before the introduction of the new formula were compared to those in the post-introduction period. RESULTS There were 126 patients with major burns (≥20% total body surface area burnt) included in the study. The median fluid volume administration pre-hospital after introduction of The Alfred formula was 0.35 (0.22-0.44) mL/kg/%TBSA burnt, which was significantly higher than 0.14 (0.04-0.26) mL/kg/%TBSA administered in the prior period (p=0.013). There was no significant change in physiological endpoints associated with the increased volume. At 24 h, the volume of fluid administered in patients when The Alfred formula was used was 4.9±1.6 mL/kg/%TBSA, which was not significantly higher than the volume administered before 2007 of 4.8±2.2 mL/%TBSA/kg (p=0.802). DISCUSSION The Alfred pre-hospital fluid formula has resulted in patients receiving significantly more fluids early, although still below volumes suggested by the Parkland formula. There were no adverse effects of this increased volume detected over the study period. The Alfred pre-hospital fluid formula appears to be safe and more effective in delivering fluid volumes predicted by the current 'gold standard'.

Abstract
BACKGROUND In practice, current burn resuscitation formulas, designed to estimate 24-hour fluid resuscitation needs, provide only a starting point for resuscitation. To simplify this process, we devised the "rule of 10" to derive the initial fluid rate. METHODS We performed an in silico study to determine whether the rule of 10 would result in acceptable initial fluid rates for adult patients. A computer application using Java (Sun Microsystems Inc., Santa Clara, CA) generated a set of 100,000 random weights and percentage of total body surface area (%TBSA) values with distributions matching the model characteristics with which the initial fluid rate was calculated using the rule of 10. The initial rate for 100,000 simulations was compared with initial rates calculated by using either the modified Brooke (MB, 2 mL/kg/%TBSA) or the Parkland (PL, 4 mL/kg/%TBSA) formulas. RESULTS Analysis of calculated initial fluid rates using the rule of 10 showed that 87.8% (n = 87,840) of patients fell between the initial rates derived by the MB and the PL formulas. Less than 12% (n = 11,502) of patients had rule of 10 derived initial rates below the MB. Among these patients, the median difference of the initial rate was 14 mL/hr (range, 2-212 mL/hr). Among those who had initial rule of 10 calculated rates greater than the PL formula (<1%, n = 658), the median difference in rate was 33 mL/hr (range, 1-213 mL/hr), with a mean %TBSA of 21% +/- 1% and mean weight of 130 kg +/- 11 kg. CONCLUSION For the majority of adult burn patients, the rule of 10 approximates the initial fluid rate within acceptable ranges.

Abstract
Burn injury is a complex traumatic event with various local and systemic effects, affecting several organ systems beyond the skin. The pathophysiology of the burn patient shows the full spectrum of the complexity of inflammatory response reactions. In the acute phase, inflammation mechanism may have negative effects because of capillary leak, the propagation of inhalation injury and the development of multiple organ failure. Attempts to mediate these processes remain a central subject of burn care research. Conversely, inflammation is a necessary prologue and component in the later-stage processes of wound healing. In this review, we are attempting to present the current science of burn wound pathophysiology and wound healing. We also describe the evolution of innovative strategies for burn management.

Abstract
Administration of resuscitation volumes far beyond the estimates established by burn-body weight resuscitation formulas has been well documented. The reasons behind this increase are not clear. We sought to determine if our resuscitation volumes had increased and, if so, what factors were related to their increase. A retrospective chart review identified 154 patients admitted with burns greater than 20% of their BSA during the years of 1975-1976 (period 1), 1990-1991 (period 2), and 2006-2007 (period 3). Charts were reviewed for total fluids (crystalloid, colloid, and blood products) and opioids given before admission, during the first 8 hours of treatment, the next 16 hours of treatment, and the following 24 hours of treatment. Opioids were converted to opioid equivalents (OE). Multiple regression analysis was performed to determine the effects of variables of interest and control for confounders. Significance was assumed at the P < .05 level. Resuscitation fluid volumes increased significantly among adults from 3.97 ml/kg/%BSA during the first period to 6.40 ml/kg/%BSA during the third period (P < .01). The same trend in children <30 kg was not seen (P = .72). Fluid administered during the first 24 hours was significantly associated with age, BSA, intubation, latter two study periods, and opioid administration. Fluid administration was consistently associated with opioid administration at all measured time points. At 24 hours postburn, patients who received 2 to 4 OE/kg required an average of additional 3,650 +/- 1,704 ml of fluid, those receiving 4 to 6 OE/kg had required an average of 25,154 +/- 4,386 ml, and those who received >6 OE kg had required an average of 32,969 +/- 3,982 ml. In this single center retrospective study, we have shown a statistically significant increase in resuscitation fluids (from 1975 to 2007) and an association of resuscitation volumes with opioids. Opioids have been shown to increase resuscitation volumes in critically ill patients through both central and peripheral effects on the cardiovascular system. Because increased fluid resuscitation has been associated with adverse consequences in other studies, further research on alternative pain control strategies in thermally injured patients is warranted.
