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 To evaluate the frequency of intra-abdominal hypertension in major burn
patients and its association with the occurrence of acute kidney injury. Methods This was a prospective cohort study of a population of burn patients
hospitalized in a specialized intensive care unit. A convenience sample was
taken of adult patients hospitalized in the period from 1 August 2015 to 31
October 2016. Clinical and burn data were collected, and serial
intra-abdominal pressure measurements taken. The significance level used was
5%. Results A total of 46 patients were analyzed. Of these, 38 patients developed
intra-abdominal hypertension (82.6%). The median increase in intra-abdominal
pressure was 15.0mmHg (interquartile range: 12.0 to 19.0). Thirty-two
patients (69.9%) developed acute kidney injury. The median time to
development of acute kidney injury was 3 days (interquartile range: 1 - 7).
The individual analysis of risk factors for acute kidney injury indicated an
association with intra-abdominal hypertension (p = 0.041), use of
glycopeptides (p = 0.001), use of vasopressors (p = 0.001) and use of
mechanical ventilation (p = 0.006). Acute kidney injury was demonstrated to
have an association with increased 30-day mortality (log-rank, p =
0.009). Conclusion Intra-abdominal hypertension occurred in most patients, predominantly in
grades I and II. The identified risk factors for the occurrence of acute
kidney injury were intra-abdominal hypertension and use of glycopeptides,
vasopressors and mechanical ventilation. Acute kidney injury was associated
with increased 30-day mortality.

Abstract
The Special Interest Groups of the American Burn Association provide a forum for interested members of the multidisciplinary burn team to congregate and discuss matters of mutual interest. At the 47th Annual Meeting of the American Burn Association in Chicago, IL, the Fluid Resuscitation Special Interest Group sponsored a special symposium on burn resuscitation. The purpose of the symposium was to review the history, current status, and future direction of fluid resuscitation of patients with burn shock. The reader will note several themes running through the following presentations. One is the perennial question of the proper role for albumin or other fluid-sparing strategies. Another is the unique characteristics of the pediatric burn patient. A third is the need for multicenter trials of burn resuscitation, while recognizing the obstacles to conducting randomized controlled trials in this setting.

Abstract
Recognition of fluid creep has driven a large amount of the scientific investigation in the area of acute fluid resuscitation for burn patients. The role of colloids in ameliorating fluid creep is controversial, despite the fact that a fluid-sparing effect of colloids has been recognized for some time. All but one of the available prospective studies using colloids are more than a decade old, and a modern randomized controlled trial (RCT) comparing crystalloids to colloids is long overdue. While urinary output continues to be the main endpoint for fluid titration, there has been a moderate amount of interest in the use of transpulmonary thermodilution to guide fluid resuscitation. The available studies have found that transpulmonary thermodilution has had an inconsistent effect on limiting fluid resuscitation volumes and improving clinical outcomes. Computerized Decision Support Systems show great promise in optimizing fluid titration and reducing fluid resuscitation volumes, and an RCT comparing Computerized Decision Support Systems with conventional titration approaches will be the important next step. Use of high-dose vitamin C (ascorbic acid) has become a popular approach to limit fluid resuscitation volumes and edema formation, but it has been investigated in only two clinical studies: one a pseudo-randomized prospective study and the other a retrospective study. Improvements in clinical outcome have not been convincingly demonstrated, and concerns persist surrounding the possibility of induction of an osmotic diuresis, leading to intravascular volume depletion. An RCT is urgently required to evaluate high-dose vitamin C as an adjunct to crystalloid resuscitation compared with the use of crystalloids alone.

Abstract
OBJECTIVE Pediatric burn patients are more susceptible to burn shock than adults, and an effective fluid management protocol is critical to successful resuscitation. Our research aim was to investigate the safety and efficacy of two protocols for pediatric burn patients for use within the first 24h. METHODS A total of 113 pediatric burn patients were enrolled from January 2007 to October 2012. Of those patients, 57 received fluid titration regimens of alternating crystalloids and colloids once within 2h in the first 24h after burn (Group A), whereas the remaining patients received regimens of alternating crystalloids and colloids once within 1h in the first 24h after burn (Group B). The safety, fluid volume infused and urine output were recorded and compared. RESULTS All the patients survived in the first 24h after burn. There were no significant differences between Group A and Group B in lactic acid (LA) level and base excess (BE). The water infused in Group A were greater than that of Group B in the first 24h (P=0.024). No significant differences were found in total volume intake and hourly urine output between the 2 groups in the first 24h. CONCLUSION The implementation of fluid resuscitation using either protocol A or protocol B is safe and effective for pediatric burn patients in the first 24h. The total fluid infused were similar between two protocols. But using protocol A may be more convenient and labor-saving for nurses.

Abstract
Burn injury is a leading cause of unintentional death and injury in children, with the majority being minor (less than 10%). However, a significant number of children sustain burns greater than 15% total body surface area (TBSA), leading to the initiation of the systemic inflammatory response syndrome. These patients require IV fluid resuscitation to prevent burn shock and death. Prompt resuscitation is critical in pediatric patients due to their small circulating blood volumes. Delays in resuscitation can result in increased complications and increased mortality. The basic principles of resuscitation are the same in adults and children, with several key differences. The unique physiologic needs of children must be adequately addressed during resuscitation to optimize outcomes. In this review, we will discuss the history of fluid resuscitation, current resuscitation practices, and future directions of resuscitation for the pediatric burn population.

200mM hypertonic saline resuscitation attenuates intestinal injury and inhibits p38 signaling in rats after severe burn trauma. Burns 2017; 43:1693-1701. [PMID: 28778754 DOI: 10.1016/j.burns.2017.04.013] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2017] [Revised: 03/15/2017] [Accepted: 04/11/2017] [Indexed: 12/24/2022]
Abstract
BACKGROUND An overabundant discharge of inflammatory mediators plays a significant role in intestinal injury throughout the early stages of critical burns. The present study aims to explore the outcome of 200mM hypertonic saline (HS) resuscitation on the intestinal injury of critically burned rats. MATERIALS AND METHODS Fifty-six Sprague-Dawley rats were randomized into three groups: sham group (group A), burn plus lactated Ringer's group (group B), and burn plus 200mM HS group (group C). Samples from the intestine were isolated and assayed for wet-weight-to-dry-weight (W/D) ratio, histopathology analyses, and p38 mitogen-activated protein kinase (MAPK) activity. Serum interleukin 1β (IL-1β) and high mobility group protein box 1 (HMGB1) concentrations were also examined. RESULTS Initial resuscitation with 200mM Na+ HS significantly decreased the intestinal W/D ratio and improved intestinal histopathology caused by severe burn. HS resuscitation also inhibited the increase of serum IL-1β and HMGB1 concentrations, and p38 MAPK activity in the intestine of critically burned rats. CONCLUSIONS The overall findings of this study suggest that preliminary resuscitation with 200mM HS after severe thermal injury reduces intestinal edema, inhibits systemic inflammatory response, and attenuates intestinal p38 MAPK activation, thus reduces burns-induced intestinal injury.

Abstract
BACKGROUND Optimal fluid resuscitation of burn patients with burns greater than 20% total body surface area is critical to prevent burn shock during the initial 24 hours to 48 hours postburn. Currently, most resuscitation formulas incorporate the patient's weight when estimating 24-hour fluid requirements. The objective of this study was to determine the impact of weight on fluid resuscitation requirements and outcomes during the initial 24 hours after admission. METHODS We performed a retrospective review of patients admitted to our burn intensive care unit from December 2007 to April 2013, resuscitated with a computerized decision support system. We classified patients into body mass index (BMI) categories of underweight (BMI: <18.5), normal (BMI: 18.5-24.9), overweight (BMI: 25.0-29.9), or obese (BMI: >30.0). We also calculated the percent difference from ideal body weight (IBW) and compared 24-hour fluid volumes received. RESULTS Patients with missing weight and/or height values were excluded from the study, resulting in a final cohort of 161 patients for analysis. Mean total body surface area was 42 ± 20% with a full thickness burn of 18 ± 23%. Mean age, weight, and height were 47 ± 19 years, 83 ± 19 kg, and 68 ± 4 inches, respectively. IBW for this cohort was 68 ± 11 kg with a BMI of 28 ± 6. Univariate analysis showed significant differences in 24-hour resuscitation volumes (mL/kg) between normal and obese patients (p < 0.05). Further analysis revealed that increasing percent difference from IBW was associated with lower fluid volumes. Although obesity was not associated with inhalation injury or renal replacement therapy, it was correlated to an increased risk for mortality (p < 0.05). CONCLUSION This analysis showed that increasing weight was associated with lower fluid resuscitation volume requirements and a higher mortality rate, despite the low incidence of inhalation injury and renal replacement therapy in our obese patients. The use of actual body weight to drive resuscitation volumes may result in overresuscitation of obese patients, depending on the resuscitation formula. Further studies are needed to better explain the relationship between mortality and obesity in burn patients. LEVEL OF EVIDENCE Therapeutic/care management, level IV.

Abstract
LEARNING OBJECTIVES After studying this article, the participant should be able to: 1. Explain the epidemiology of severe burn injury in the context of socioeconomic status, gender, age, and burn cause. 2. Describe challenges with burn depth evaluation and novel methods of adjunctive assessment. 3. Summarize the survival and functional outcomes of severe burn injury. 4. State strategies of fluid resuscitation, endpoints to guide fluid titration, and sequelae of overresuscitation. 5. Recognize preventative measures of sepsis. 6. Explain intraoperative strategies to improve patient outcomes, including hemostasis, restrictive transfusion, temperature regulation, skin substitutes, and Meek skin grafting. 7. Translate updates in the pathophysiology of hypertrophic scarring into novel methods of clinical management. 8. Discuss the potential role of free tissue transfer in primary and secondary burn reconstruction. SUMMARY Management of burn-injured patients is a challenging and unique field for plastic surgeons. Significant advances over the past decade have occurred in resuscitation, burn wound management, sepsis, and reconstruction that have improved outcomes and quality of life after thermal injury. However, as patients with larger burns are resuscitated, an increased risk of nosocomial infections, sepsis, compartment syndromes, and venous thromboembolic phenomena have required adjustments in care to maintain quality of life after injury. This article outlines a number of recent developments in burn care that illustrate the evolution of the field to assist plastic surgeons involved in burn care.

Abstract
INTRODUCTION The depth of burn has been an important factor often overlooked when estimating the total resuscitation fluid needed for early burn care. The goal of this study was to determine the degree to which full-thickness (FT) involvement affected overall 24-hour burn resuscitation volumes. METHODS We performed a retrospective review of patients admitted to our burn intensive care unit from December 2007 to April 2013, with significant burns that required resuscitation using our computerized decision support system for burn fluid resuscitation. We defined the degree of FT involvement as FT Index (FTI; percentage of FT injury/percentage of total body surface area (TBSA) burned [%FT / %TBSA]) and compared variables on actual 24-hour fluid resuscitation volumes overall as well as for any given burn size. RESULTS A total of 203 patients admitted to our burn center during the study period were included in the analysis. Mean age and weight were 47 ± 19 years and 87 ± 18 kg, respectively. Mean %TBSA was 41 ± 20 with a mean %FT of 18 ± 24. As %TBSA, %FT, and FTI increased, so did actual 24-hour fluid resuscitation volumes (mL/kg). However, increase in FTI did not result in increased volume indexed to burn size (mL/kg per %TBSA). This was true even when patients with inhalation injury were excluded. Further investigation revealed that as %TBSA increased, %FT increased nonlinearly (quadratic polynomial) (R = 0.994). CONCLUSION Total burn size and FT burn size were both highly correlated with increased 24-hour fluid resuscitation volumes. However, FTI did not correlate with a corresponding increase in resuscitation volumes for any given burn size, even when patients with inhalation injury were excluded. Thus, there are insufficient data to presume that those who receive more volume at any given burn size are likely to be mostly full thickness or vice versa. This was influenced by a relatively low sample size at each 10%TBSA increment and larger burn sizes disproportionately having more FT burns. A more robust sample size may elucidate this relationship better. LEVEL OF EVIDENCE Therapeutic/care management study, level IV.

Abstract
BACKGROUND Intra-abdominal hypertension (IAH) affects almost every organ sytem.If it is not detected early and corrected, mortality would be high. The prevalence of IAH and abdominal compartment syndrome (ACS) at Kenyatta National Hospital (KNH) critical care units is not known. The aim of this sudy was to determine the prevalence and factors associated with development of IAH/ACS among critically ill surgical patients. METHODS This was a cross sectional descriptive study involving surgical patients in critical care units at KNH, carried out from March 2015 to October 2015. One hundred and thirteen critically ill and ventilated patients 13 years or older were recruited into the study. Krohn's intravesical method was used to measure intra- abdominal pressure (IAP). Measurements were done at first contact, then at 12 and 24 h. Additional parameters recorded included: laboratory tests such as serum bilirubin and total blood count as well as clinical parameters such as urine output, vital signs and peak airway pressure, among others. Frequency, means and standard deviation were used to describe the data. Categorical variables e.g. age, were analysed using Chi square test and continous variables using student 't' test and Mann Whitney test as appropriate RESULT: A total of 113 consecutive surgical patients admitted to the critical care units were recruited. Of our study population, 71.7% (by IAP max) and 67.3% (by IAP mean) had IAH. Abdominal compartment syndrome (ACS) developed in 4.4% of the population. The following factors were significant determinants of risk of IAH : amount of IV fluids over 24 h (3949.6 vs 2931.1, p = 0.003, adjusted OR 1.0 [1.0-1.002]), haemoglobin values at admission (9.9 vs 12.0, p = <0.012, adjusted OR 0.6 [0.4-0.9]), peak airway pressure (28.4 vs 17.3; p = 0.018, adjusted OR 1.6 [1.1-2.4]) and synchronised intermittent mandatory ventilation (SIMV) (60 vs 32; p = 0.041, adjusted OR 1.4 [0.78-2.04]). Of those who had IAH; age, amount of iv fluids over 24 h, fluid balance and ventilator mode were significant determinants of risk of progression to ACS . CONCLUSION The prevalence of intraabdominal hypertension and abdominal compartment syndrome at KNH is high. Clinical parameters pertaining to fluids administration and ventilator mode are siginificant determinants.

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
Since 1968, when Baxter and Shires developed the Parkland formula, little progress has been made in the field of fluid therapy for burn resuscitation, despite advances in haemodynamic monitoring, establishment of the 'goal-directed therapy' concept, and the development of new colloid and crystalloid solutions. Burn patients receive a larger amount of fluids in the first hours than any other trauma patients. Initial resuscitation is based on crystalloids because of the increased capillary permeability occurring during the first 24 h. After that time, some colloids, but not all, are accepted. Since the emergence of the Pharmacovigilance Risk Assessment Committee alert from the European Medicines Agency concerning hydroxyethyl starches, solutions containing this component are not recommended for burns. But the question is: what do we really know about fluid resuscitation in burns? To provide an answer, we carried out a non-systematic review to clarify how to quantify the amount of fluids needed, what the current evidence says about the available solutions, and which solution is the most appropriate for burn patients based on the available knowledge.

Abstract
OBJECTIVE To compare early versus delayed albumin resuscitation in children with burns in terms of clinical outcome and response. DESIGN Randomized controlled trial. SETTING Burn center at a tertiary care teaching hospital. PATIENTS Forty-six children aged 1-12 years with burns greater than 15-45% total body surface area admitted within 12 hours of burn injury. INTERVENTIONS Fluid resuscitation was based on the Parkland formula (3 mL/kg/% total body surface area), adjusted according to urine output. Patients received 5% albumin solution between 8 and 12 hours post burn in the intervention group (n = 23) and 24 hours post burn in the control group (n = 23). Both groups were assessed for reduction in crystalloid fluid infusion during resuscitation, development of fluid creep, and length of hospital stay. MEASUREMENTS AND MAIN RESULTS There was no difference between groups regarding age, weight, sex, % total body surface area, cause of burn, or severity scores. The median crystalloid fluid volume required during the first 3 days post burn was lower in the intervention than in the control group (2.04 vs 3.05 mL/kg/% total body surface area; p = 0.025 on day 1; 1.2 vs 1.71 mL/kg/% total body surface area; p = 0.002 on day 2; and 0.82 vs 1.3 mL/kg/% total body surface area; p = 0.002 on day 3). The median urine output showed no difference between intervention and control groups (2.1 vs 2.0 mL/kg/hr; p = 0.152 on day 1; 2.58 vs 2.54 mL/kg/hr; p = 0.482 on day 2; and 2.9 vs 3.0 mL/kg/hr; p = 0.093 on day 3). Fluid creep was observed in 13 controls (56.5%) and in one patient (4.3%) in the intervention group. The median length of hospital stay was 18 days (range, 15-21 d) for controls and 14 days (range, 10-17 d) in the intervention group (p = 0.004). CONCLUSIONS Early albumin infusion in children with burns greater than 15-45% total body surface area reduced the need for crystalloid fluid infusion during resuscitation. Significantly fewer cases of fluid creep and shorter hospital stay were also observed in this group of patients.

Abstract
Background The effect of decompressive laparotomy on outcomes in patients with abdominal compartment syndrome has been poorly investigated. The aim of this prospective cohort study was to describe the effect of decompressive laparotomy for abdominal compartment syndrome on organ function and outcomes. Methods This was a prospective cohort study in adult patients who underwent decompressive laparotomy for abdominal compartment syndrome. The primary endpoints were 28‐day and 1‐year all‐cause mortality. Changes in intra‐abdominal pressure (IAP) and organ function, and laparotomy‐related morbidity were secondary endpoints. Results Thirty‐three patients were included in the study (20 men). Twenty‐seven patients were surgical admissions treated for abdominal conditions. The median (i.q.r.) Acute Physiology And Chronic Health Evaluation (APACHE) II score was 26 (20–32). Median IAP was 23 (21–27) mmHg before decompressive laparotomy, decreasing to 12 (9–15), 13 (8–17), 12 (9–15) and 12 (9–14) mmHg after 2, 6, 24 and 72 h. Decompressive laparotomy significantly improved oxygenation and urinary output. Survivors showed improvement in organ function scores, but non‐survivors did not. Fourteen complications related to the procedure developed in eight of the 33 patients. The abdomen could be closed primarily in 18 patients. The overall 28‐day mortality rate was 36 per cent (12 of 33), which increased to 55 per cent (18 patients) at 1 year. Non‐survivors were no different from survivors, except that they tended to be older and on mechanical ventilation. Conclusion Decompressive laparotomy reduced IAP and had an immediate effect on organ function. It should be considered in patients with abdominal compartment syndrome. Improves organ function

Abstract
OBJECTIVES The Parkland formula for maintenance and resuscitation fluid requirements in the first 24 hours after pediatric burns is widely used, but calculation errors frequently occur. Two different novel aids to calculation, a dedicated electronic device and a mechanical disc calculator, are described and compared with the conventional method of calculation (pen and paper, assisted by a general purpose calculator). METHODS In a blinded randomized volunteer study, 21 participants performed a total of 189 calculations using simulated patient data to compare the accuracy and speed of 3 different methods for calculating resuscitation fluid requirements based on the pediatric Parkland formula. Bespoke software generated the simulated patient data and recorded accuracy and speed of all participant responses. RESULTS Sixty-five percent of calculations with the electronic device, 35% using the disc and 44% using the pen/paper methods were within ±5% of the correct value and considered "correct" for clinical purposes. The method used strongly affected the tendency to make errors (logistic regression). With thresholds of error magnitude classed as very small (>5%), small (>25%), medium (>50%) and large (>100%) of the correct value respectively, the electronic method produced fewer errors than both disc and pen/paper methods at all error thresholds. Disc produced more errors than pen/paper at the greater than 5% threshold but fewer at the greater than 25%, greater than 50%, and greater than 100% thresholds. CONCLUSIONS Both novel devices provide safer and faster alternatives to conventional methods for calculation of fluid requirements in pediatric burns.

Abstract
INTRODUCTION Secondary abdominal compartment syndrome (ACS) can occur in trauma patients without abdominal injuries. Surgical management of patients presenting with secondary ACS after isolated traumatic lower extremity vascular injury (LEVI) continues to evolve, and associated outcomes remain unknown. METHODS From January 2006 to September 2011, 191 adult trauma patients presented to the Ryder Trauma Center, an urban level I trauma center in Miami, Florida with traumatic LEVIs. Among them 10 (5.2 %) patients were diagnosed with secondary ACS. Variables collected included age, gender, mechanism of injury, and clinical status at presentation. Surgical data included vessel injury, technical aspects of repair, associated complications, and outcomes. RESULTS Mean age was 37.4 ± 18.0 years (range 16-66 years), and the majority of patients were males (8 patients, 80 %). There were 7 (70 %) penetrating injuries (5 gunshot wounds and 2 stab wounds), and 3 blunt injuries with mean Injury Severity Score (ISS) 21.9 ± 14.3 (range 9-50). Surgical management of LEVIs included ligation (4 patients, 40 %), primary repair (1 patient, 10 %), reverse saphenous vein graft (2 patients, 20 %), and PTFE interposition grafting (3 patients, 30 %). The overall mortality rate in this series was 60 %. CONCLUSIONS The association between secondary ACS and lower extremity vascular injuries carries high morbidity and mortality rates. Further research efforts should focus at identifying parameters to accurately determine resuscitation goals, and therefore, prevent such a devastating condition.

Abstract
Total body surface area (TBSA) burned is a powerful descriptor of burn severity and influences the volume of resuscitation required in burn patients. The incidence and severity of TBSA overestimation by referring institutions (RIs) in children transferred to a burn center (BC) are unclear. The association between TBSA overestimation and overresuscitation is unknown as is that between TBSA overestimation and outcome. The trauma registry at a BC was queried over 7.25 years for children presenting with burns. TBSA estimate at RIs and BC, total fluid volume given before arrival at a BC, demographic variables, and clinical variables were reviewed. Nearly 20 per cent of children arrived from RIs without TBSA estimation. Nearly 50 per cent were overestimated by 5 per cent or greater TBSA and burn sizes were overestimated by up to 44 per cent TBSA. Average TBSA measured at BC was 9.5 ± 8.3 per cent compared with 15.5 ± 11.8 per cent as measured at RIs (P < 0.0001). Burns between 10 and 19.9 per cent TBSA were overestimated most often and by the greatest amounts. There was a statistically significant relationship between overestimation of TBSA by 5 per cent or greater and overresuscitation by 10 mL/kg or greater (P = 0.02). No patient demographic or clinical factors were associated with TBSA overestimation. Education efforts aimed at emergency department physicians regarding the importance of always calculating TBSA as well as the mechanics of TBSA estimation and calculating resuscitation volume are needed. Further studies should evaluate the association of TBSA overestimation by RIs with adverse outcomes and complications in the burned child.

Abstract
BACKGROUND Gastrointestinal complications occur frequently in intensive care patients with severe burns. Intestinal infarction and its deleterious consequences result in high mortality despite rapid surgical intervention. Our objective was to evaluate the aetiology of gastrointestinal infarction in intensive care patients with severe burns. STUDY DESIGN We retrospectively evaluated all of the severe-burn victims at the burn unit of the Medical University of Vienna from 01/2002 to 06/2012 for whom a gastrointestinal infarction was diagnosed during their inpatient stay on computed-tomography, in the context of acute laparotomy, or upon autopsy by aetiology. RESULTS After a severe thermal injury, 17 patients suffered a gastrointestinal infarction during their stay. In 82% of those patients, non-occlusive mesenteric ischaemia (NOMI) was identified as the cause of the gastrointestinal infarction. Patients with an embolic infarction tended to be older (78.0years embolism vs. 53.4 NOMI, mean, p<0.01), with a lower abbreviated burn severity index (8.7 embolism vs. 10.4 NOMI, mean, p<0.02) and a smaller total body surface area burned (20% embolism vs. 48% NOMI, mean, p<0.01) than those with a non-occlusive mesenterial ischaemia. No patients with an embolic infarction or any of the females in the entire gastrointestinal infarction group survived this event, resulting in a mortality rate of 100% for the embolic infarction group and female group. The decisive factor for surviving a NOMI was age (median age: male survivors 28years vs. nonsurvivors 66years (of this median, males=72years and females=60years), p<0.02). CONCLUSION The results of our study clearly demonstrate that in severe-burn intensive care patients, non-occlusive mesenteric ischaemia is the most frequent cause of gastrointestinal infarction and that the decisive factor for survival is the patient's age.

Abstract
Objective Severe burns are devastating injuries that result in considerable systemic inflammation and often require resuscitation with large volumes of fluid. The result of massive resuscitation is often raised intra-abdominal pressures leading to Intra-abdominal hypertension (IAH) and the secondary abdominal compartment syndrome. The objective of this study is to conduct (1) a 10 year retrospective study to investigate epidemiological factors contributing to burn injuries in Alberta, (2) to characterize fluid management and incidence of IAH and ACS and (3) to review fluid resuscitation with a goal to identify optimal strategies for fluid resuscitation. Design A comprehensive 10-year retrospective review of burn injuries from 1999. Outcome Measures Age, sex, date, mechanism of injury, location of incident, on scene vitals and GCS, type of transport to hospital and routing, ISS, presenting vitals and GCS, diagnoses, procedures, complications, hospital LOS, ICU LOS, and events surrounding the injury. Results One hundred and seventy five patients (79.4% M, 20.6% F) were identified as having traumatic burn injuries with a mean ISS score of 21.8 (±8.3). The mean age was 41.6 (±17.5) (range 14-94) years. Nearly half (49.7%) of patients suffered their injuries at home, 17.7% were related to industrial incidents and 14.3% were MVC related. One hundred and ten patients required ICU admission. ICU LOS 18.5 (±8.8) days. Hospital LOS 38.0 (±37.8) days. The mean extent of burn injury was 31.4 (±20.9) % TBSA. Nearly half of the patients suffered inhalational injuries (mild 12.5%, moderate 13.7%, severe 9.1%). Thirty-nine (22.2%) of patients died from their injuries. Routine IAP monitoring began in September, 2005 with 15 of 28 patients having at least two IAP measurements. The mean IAP was 16.5 (±5.7) cm H2O (range: 1-40) with an average of 58 (±97) IAP measurements per patient. Those patients with IAP monitoring had an average TBSA of 35.0 (±16.0)%, ISS of 47.5 (±7.5). The mean 48 hr fluid balance was 25.6 (±11.1)L exceeding predicted Parkland formula estimates by 86 (±32)%. Conclusions Further evaluation of IAP monitoring is needed to further characterize IAP and fluid resuscitation in patients with burn injuries.

Abstract
INTRODUCTION Since the second World Congress on the Abdominal Compartment Syndrome (WCACS) in Noosa 2 years ago, interest and publications on intra-abdominal hypertension (IAH) and ACS have increased exponentially. This paper aimed to critically review recent publications and put this new data into the context of already acquired knowledge concerning IAH/ACS. METHODS A Medline and PubMed search was performed from January 2005 up to now using "intra-abdominal pressure (IAP)", "intra-abdominal hypertension (IAH)", "abdominal compartment syndrome (ACS)" and "decompressive laparotomy" as search items. RESULTS Although consensus definitions of IAH/ACS have been formulated recently, data on awareness are still disconcerting. Several groups refined current IAP measurement techniques and tested new direct IAP measurement devices for use in selected subpopulations. A series of recent publications identified specific patient subpopulations in IAH/ACS, like patients with burns or severe acute pancreatitis, with their specific pathophysiology and therapy. Although many studies already assessed the effect of elevated IAP on regional and micro-circulatory organ perfusion, a number of new publications attempted to unravel the link between elevated IAP and more "downstream" organ function or histology. Finally, therapy for IAH/ACS still reveals more questions than it answers. Global resuscitation does not necessarily equate with organ resuscitation. In fact, fluid-resuscitation may even induce IAH/ACS. CONCLUSIONS After publication of consensus guidelines on IAH/ACS, there is an urgent need for human intervention studies and, in parallel, clinically relevant animal models. Given moderately low incidence of ACS and the complex and interrelated pathologies of the critically ill patient with IAH/ACS, large animal models of pathology-induced IAH/ACS might create the opportunity to gain clinically relevant knowledge on the treatment of IAH/ACS.

Abstract
INTRODUCTION Intra-abdominal hypertension (IAH) and subsequent abdominal compartment syndrome (ACS) in burned patients is common. This sequence of events typically occurs in patients with larger burns receiving high volume fluid resuscitation. METHODS A review of the literature was performed. The National Library of Medicine (PUBMED) was queried for "Burn" and "Abdominal Compartment Syndrome". Twenty-nine articles were retained for study. RESULTS Abdominal pressure monitoring is appropriate in all patients with burns that require significant volume resuscitation (>30% total burned surface area- TBSA). Prevention of ACS in burns includes limiting fluid resuscitation, burn escharotomy, and percutaneous drainage when abdominal pressures are reaching perilous levels. Treatment includes all of the above and in addition, decompressive laparotomy when needed. However, despite decompressive laparotomy, mortality rates among burn victims with ACS remain unacceptably high. CONCLUSION Increasing amounts of volume delivery are associated with an increased risk of IAH. Therefore, intra-abdominal pressure should be monitored in all burn patients requiring massive fluid resuscitation. Escharotomy, paracentesis, and decompressive laparotomy may all be needed to counter the side effects of appropriate fluid resuscitation in the severely burned patient. Nevertheless, the prognosis in burn patients developing ACS is grim.

Abstract
INTRODUCTION The Secondary Abdominal Compartment Syndrome (SACS) refers to cases of the ACS that do not originate from the abdominopelvic region. With greater awareness of the physiologic consequences of raised intra-abdominal hypertension (IAH), cases of the SACS are being increasingly described. The prior treatment or the presence of a partially open abdomen does not preclude the ACS if the abdomen and viscera continue to swell or the clinician is not vigilant in monitoring intra-abdominal pressure (IAP). Such recurrent cases (RACS) have been defined as those which redevelop following the previous medical or surgical treatment of primary or SACS. Although there has been a diverse range of etiologies implicated, these cases seem to be linked by the common occurrence of severe shock requiring aggressive fluid resuscitation. The aim of this paper is to thus to review the historical background, awareness, definitions, pathophysiological implications and treatment options for SACS and RACS. METHODS This review will focus on the available literature regarding SACS and RACS. A Medline and Pubmed search was performed using the keywords; secondary abdominal compartment syndrome AND secondary AND tertiary AND recurrent AND abdominal compartment syndrome AND intra-abdominal pressure AND intra-abdominal hypertension. Bibliographies of recovered papers were hand-searched for other appropriate references. The resulting references were included in the current review on the basis of relevance and scientific merit Results: There has been remarkably little specific study of these entities outside of specific groups such as those injured by thermal or traumatic injury. The epidemiology, risk factors for, treatment of and most importantly, strategies for prevention all remain scientifically unknown and therefore based on opinion. Notable, although small, studies suggest that specific resuscitation practices may avert these conditions. CONCLUSIONS ACS can occur in any patient who is critically ill and subject to visceral and somatic swelling, regardless of whether the inciting pathology is extra-abdominal. The ACS may also reoccur with recurrent shock and swelling even if previous therapies had partially addressed IAH. Therefore IAP measurements should be considered a routine monitoring for the critically ill, especially those subjected to shock and requiring a subsequent resuscitation. Much further study is required to understand the differences in etiology, diagnosis, pathophysiology, and treatment for all cases of the ACS.

Abstract
Burn injuries are highly complex and affect almost every major organ system in the body. The treatment of burn patients requires the presence of a well-organized team of caregivers who understand the multifaceted consequences of burn injuries and who are adept at coordinating care. An understanding of the multitude of abnormalities that must be addressed helps to guide therapy in these patients. Careful anesthetic and perioperative management of these patients carries special importance in this fragile patient population as a part of their often lengthy recovery and rehabilitation.

Abstract
BACKGROUND Burn resuscitation, including titration of fluids and administration of colloids, is often driven by physicians' orders. Inconsistencies in burn resuscitation cause overresuscitation, which has adverse consequences. METHODS Retrospective chart reviews were completed to evaluate fluid resuscitation and complications for 12 months before and after development and implementation of a nurse-driven burn resuscitation protocol. RESULTS Before implementation of the protocol, results at 24 hours after injury indicated that 58% of patients were overresuscitated, had a serum level of lactate of at least 2 mmol/L (100%), and had complications (pulmonary edema 20%, abdominal compartment syndrome 7%, acute lung injury/acute respiratory distress syndrome 30%) within the first 5 days. Two outcomes differed from before to after implementation of the protocol: serum level of lactate at 24 hours (t(37.8) =2.38, P =.007) and central venous pressure at 48 hours (t(31) =2.27, P =.03). After implementation of the protocol, no patients had abdominal compartment syndrome develop. CONCLUSIONS Implementation of the nurse-driven burn resuscitation protocol improved nurses' awareness and assessment of fluid status during resuscitation and improved patients' outcomes.

Abstract
CONTEXT Inadequate fluid resuscitation of acute burns may result in hypovolaemic shock. Excessive fluid resuscitation may result in fluid overload. A nomogram which uses the popular Parkland formula and '4-2-1' regime has been recently described to facilitate the calculation of fluid requirements in children during the first 24 h following burn injury. OBJECTIVE To compare the accuracy and speed of calculation of three different methods (pen and paper, electronic calculator and nomogram), which all use the Parkland formula and '4-2-1' regime to calculate maintenance and resuscitation fluid requirements for children in the first 24 h after burn injury. DESIGN A randomised volunteer study using computer-generated simulated patient data. SETTING Welsh Centre for Burns, ABM University Local Health Board, Swansea, UK. Data were collected between February 2011 and October 2011. PARTICIPANTS The group consisted of 36 volunteers including trainee and consultant surgeons and anaesthetists. INTERVENTION Thirty-six participants performed 318 calculations, using each of the three methods of calculation up to three times. MAIN OUTCOME MEASURES Accuracy, speed and acceptability of the different methods. RESULTS For nomogram, calculator and pen and paper: magnitude of error [low (≥25%), medium (≥50%) and high (≥75%)]: [5.7, 4.7 and 3.8%], [12.1, 12.1 and 7.5%], [28.6, 21.9 and 16.2%]; [P <0.001, P = 0.001 and P = 0.006]. Calculation time: [s; mean (SD)]: 121 (48), 109 (52) and 240 (140); P <0.001. The mean (SD) of the difficulty scores were 17.3 (13), 20.6 (13.4) and 62.2 (23.4); P <0.001. CONCLUSION The nomogram was the most accurate method of calculating fluid requirements using the Parkland formula, was only slightly slower than the electronic calculator and was deemed the easiest to use. The nomogram is also low cost, robust, and provides a rapid means of detecting and preventing the large errors that we have shown can occur when an electronic device is used as the primary method of resuscitation fluid calculation. We, therefore, suggest that the nomogram is a suitable method for the calculation of the Parkland formula to guide resuscitation and maintenance fluid requirements in the first 24 h of paediatric burns or for cross-checking the results obtained by other means of calculation.

Abstract
OBJECTIVE We aimed to determine whether the severity of inhalation injury evokes an immune response measurable at the systemic level and to further characterize the balance of systemic pro- and anti-inflammation early after burn and inhalation injury. BACKGROUND Previously, we reported that the pulmonary inflammatory response is enhanced with worse grades of inhalation injury and that those who die of injuries have a blunted pulmonary immune profile compared with survivors. METHODS From August 2007 to June 2011, bronchoscopy was performed on 80 patients admitted to the burn intensive care unit when smoke inhalation was suspected. Of these, inhalation injury was graded into 1 of 5 categories (0, 1, 2, 3, and 4), with grade 0 being the absence of visible injury and grade 4 corresponding to massive injury. Plasma was collected at the time of bronchoscopy and analyzed for 28 immunomodulating proteins via multiplex bead array or enzyme-linked immunosorbent assay. RESULTS The concentrations of several plasma immune mediators were increased with worse inhalation injury severity, even after adjusting for age and % total body surface area (TBSA) burn. These included interleukin (IL)-1RA (P = 0.002), IL-6 (P = 0.002), IL-8 (P = 0.026), granulocyte colony-stimulating factor (P = 0.002), and monocyte chemotactic protein 1 (P = 0.007). Differences in plasma immune mediator concentrations in surviving and deceased patients were also identified. Briefly, plasma concentrations of IL-1RA, IL-6, IL-8, IL-15, eotaxin, and monocyte chemotactic protein 1 were higher in deceased patients than in survivors (P < 0.05 for all), whereas IL-4 and IL-7 were lower (P < 0.05). After adjusting for the effects of age, % TBSA burn, and inhalation injury grade, plasma IL-1RA remained significantly associated with mortality (odds ratio, 3.12; 95% confidence interval, 1.03-9.44). Plasma IL-1RA also correlated with % TBSA burn, inhalation injury grade, fluid resuscitation, Baux score, revised Baux score, Denver score, and the Sequential Organ Failure Assessment score. CONCLUSIONS The severity of smoke inhalation injury has systemically reaching effects, which argue in favor of treating inhalation injury in a graded manner. In addition, several plasma immune mediators measured early after injury were associated with mortality. Of these, IL-1RA seemed to have the strongest correlation with injury severity and outcomes measures, which may explain the blunted pulmonary immune response we previously found in nonsurvivors.

Burns 2013; 39:1060-6. [PMID: 23773791 DOI: 10.1016/j.burns.2013.05.016] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2011] [Revised: 01/09/2013] [Accepted: 05/21/2013] [Indexed: 10/26/2022]
Abstract
BACKGROUND Resuscitation fluid rates following burn are currently guided by a weight and burn size formulae, then titrated to urine output. Traditionally, 24h resuscitation is reported as volume of resuscitation received without direct consideration for the physiologic response. We propose an input-to-output ratio to describe the course of burn resuscitation and predict eventual outcomes. METHODS We reviewed admissions to a burn center from January 2003 through August 2006. Inclusion criteria were ≥20%TBSA, admission ≤8h after burn, and survived ≥24h. Demographics, input volume and urine output, and clinical outcomes were recorded. A ratio of input volume (cc/kg/%TBSA/h) to urine output (cc/kg/h) was calculated at 24h. The ratio of fluid intake to urine output reflecting an 'expected' response was developed: 4cc/kg/%TBSA/24h (0.166cc/kg/%TBSA/h) divided by 0.5-1.0cc urine/kg/h for an expected range 0.166-0.334. Subjects were classified based upon the ratio: over-responders (<0.166), expected (0.166-0.334), or under-responders (>0.334). Clinical outcomes were compared and concordance of classification to values was calculated at 12h. RESULTS 102 subjects met inclusion criteria; 29 in the over-responders, 37 in the expected, and 36 in the under-responders. Resuscitation volume was directly proportional to the calculated ratio while urine output was inversely proportional. Group mortality was 21%, 11%, and 44%, respectively, with a significant difference between the expected and under-responders (p<0.002). We found decreased ventilator-free days in the under-responders, and when deaths were excluded, decreased ICU-free days as well (p<0.05). Concordance of paired data gathered at 12h and 24h was 67% for the under-responder group. CONCLUSIONS We describe a novel ratio to classify acute resuscitation after severe burn including the patient's response. Such a classification is associated with eventual outcomes.

Abstract
Patients who suffer from severe burns develop metabolic imbalances and systemic inflammatory response syndrome (SIRS) which can result in multiple organ failure and death. Research aimed at reducing the inflammatory process has yielded new insight into burn injury therapies. In this review, we discuss strategies used to curb inflammation in burn injuries and note that further studies with high quality evidence are necessary.

Abstract
OBJECTIVE To review the evaluation and treatment of patients suffering from severe burn injury (SBI), burn shock, and smoke inhalation injury. Potential complications and prognosis associated with SBI are also discussed. DIAGNOSIS Diagnosis of burn injury and burn shock is based on patient history and clinical presentation. Superficial burn wounds may not be readily apparent for the first 48 h whereas more severe wounds will be evident at presentation. Patients are diagnosed with local or SBI by estimating total body surface area involved using the 'Rule of Nines' or the Lund-Browder chart adapted from the human literature. THERAPY Patients suffering from SBI require immediate and aggressive fluid therapy. Burn wounds require prompt cooling to prevent progressive tissue damage. Due to significant pain associated with burn wounds and therapeutic procedures, multimodal analgesia is recommended. Daily wound management including hydrotherapy, topical medications, and early wound excision and grafting is necessary with SBI. COMPLICATIONS There are numerous complications associated with SBI. The most common complications include infections, hypothermia, intra-abdominal hypertension, and abdominal compartment syndrome. PROGNOSIS The prognosis of SBI in domestic animals is unknown. Based on information derived from human literature, patients with SBI and concomitant smoke inhalation likely have a worse prognosis than those with SBI or smoke inhalation alone.

Abstract
BACKGROUND The optimal resuscitation algorithm remains elusive for patients with a large burn injury. Recent reports from the military support that larger burns that do not respond well to ongoing lactated Ringer's solution resuscitation may improve with the use of 5% albumin and vasopressors. We hypothesized that the use of 5% albumin and vasopressors, as needed, would decrease complications of fluid resuscitation and burn mortality. METHODS Fluid needs during the first 24 hours after burn injury, complications, and demographics were collected from all patients 12 years and older with burn size 20% or more of total body surface area admitted from 2003 to 2010. In March 2007, we changed our resuscitation to include the use of 5% albumin in the first 24 hours if the estimated fluid needs at 12 hours after burn would lead to a fluid volume of 6 mL/kg per percent burn at 24 hours. The patients treated before this change (Preprotocol) were compared with those treated after the guideline change (Postprotocol). RESULTS The two groups were well matched for age, burn size, and inhalation injury. Ventilator days and mortality were decreased in the Postprotocol group. There was a trend toward less intravenous fluid use in the Postprotocol group where the use of albumin was higher. There was significantly less vasopressor infusion in the Postprotocol group. There was no statistical difference in the number of escharotomies performed or overall incidence of abdominal compartment syndrome, but no patient required open laparotomy in the Postprotocol group. CONCLUSION An algorithm incorporating albumin use in the first 24 hours after burn injury was associated with the use of less vasopressor agents and lower mortality. Early albumin use was also associated with a shorter duration of mechanical ventilation in burn patients sustaining burns 20% or more total body surface area. LEVEL OF EVIDENCE Therapeutic study, level IV.

Abstract
Intra-abdominal pressure (IAP) is seldom measured by default in intensive care patients. This review summarises the current evidence on the prevalence and risk factors of intra-abdominal hypertension (IAH) to assist the decision-making for IAP monitoring.IAH occurs in 20% to 40% of intensive care patients. High body mass index (BMI), abdominal surgery, liver dysfunction/ascites, hypotension/vasoactive therapy, respiratory failure and excessive fluid balance are risk factors of IAH in the general ICU population. IAP monitoring is strongly supported in mechanically ventilated patients with severe burns, severe trauma, severe acute pancreatitis, liver failure or ruptured aortic aneurysms. The risk of developing IAH is minimal in mechanically ventilated patients with positive end-expiratory pressure < 10 cmH2O, PaO2/FiO2 > 300, and BMI < 30 and without pancreatitis, hepatic failure/cirrhosis with ascites, gastrointestinal bleeding or laparotomy and the use of vasopressors/inotropes on admission. In these patients, omitting IAP measurements might be considered.In conclusions, clear guidelines to select the patients in whom IAP measurements should be performed cannot be given at present. In addition to IAP measurements in at-risk patients, a clinical assessment of the signs of IAH should be a part of every ICU patient's bedside evaluation, leading to prompt IAP monitoring in case of the slightest suspicion of IAH development.

Abstract
Management of burn injury has always been the domain of burn specialists. Since ancient time, local and systemic remedies have been advised for burn wound dressing and burn scar prevention. Management of burn wound inflicted by the different physical and chemical agents require different regimes which are poles apart from the regimes used for any of the other traumatic wounds. In extensive burn, because of increased capillary permeability, there is extensive loss of plasma leading to shock while whole blood loss is the cause of shock in other acute wounds. Even though the burn wounds are sterile in the beginning in comparison to most of other wounds, yet, the death in extensive burns is mainly because of wound infection and septicemia, because of the immunocompromised status of the burn patients. Eschar and blister are specific for burn wounds requiring a specific treatment protocol. Antimicrobial creams and other dressing agents used for traumatic wounds are ineffective in deep burns with eschar. The subeschar plane harbours the micro-organisms and many of these agents are not able to penetrate the eschar. Even after complete epithelisation of burn wound, remodelling phase is prolonged. It may take years for scar maturation in burns. This article emphasizes on how the pathophysiology, healing and management of a burn wound is different from that of other wounds.

Abstract
BACKGROUND Management of the open abdomen is an increasingly common part of surgical practice. The purpose of this review is to examine the scientific background for the use of temporary abdominal closure (TAC) in the open abdomen as a way to modulate the local and systemic inflammatory response, with an emphasis on decompression after abdominal compartment syndrome (ACS). METHODS A review of the relevant English language literature was conducted. Priority was placed on articles published within the last 5 years. RESULTS/CONCLUSION Recent data from our group and others have begun to lay the foundation for the concept of TAC as a method to modulate the local and/or systemic inflammatory response in patients with an open abdomen resulting from ACS.

Abstract
Abdominal compartment syndrome (ACS) increases the risk for mortality in critically ill children. It occurs in association with a wide variety of medical and surgical diagnoses. Management of ACS involves recognizing the development of intra-abdominal hypertension (IAH) by intra-abdominal pressure (IAP) monitoring, treating the underlying cause, and preventing progression to ACS by lowering IAP. When ACS is already present, supporting dysfunctional organs and decreasing IAP to prevent new organ involvement become an additional focus of therapy. Medical management strategies to achieve these goals should be employed but when medical management fails, timely abdominal decompression is essential to reduce the risk of mortality. A literature review was performed to understand the role and outcomes of abdominal decompression among children with ACS. Abdominal decompression appears to have a positive effect on patient survival. However, prospective randomized studies are needed to fully understand the indications and impact of these therapies on survival in children.

Abstract
Care of the severely injured patient with burn requires correct diagnosis, appropriately tailored resuscitation, and definitive surgical management to reduce morbidity and mortality. Currently, mortality rates related to severe burn injuries continue to steadily decline due to the standardization of a multidisciplinary approach instituted at tertiary health care centers. Prompt and accurate diagnoses of burn wounds utilizing Lund-Browder diagrams allow for appropriate operative and nonoperative management. Coupled with diagnostic improvements, advances in resuscitation strategies involving rates, volumes, and fluid types have yielded demonstrable benefits related to all aspects of burn care. More recently, identification of comorbid conditions such as inhalation injury and malnutrition have produced appropriate protocols that aid the healing process in severely injured patients with burn. As more patients survive larger burn injuries, the early diagnosis and successful treatment of secondary and tertiary complications are becoming commonplace. While advances in this area are exciting, much work to elucidate immune pathways, diagnostic tests, and effective treatment regimens still remain. This review will provide an update on the critical care management of severe burns, touching on accurate diagnosis, resuscitation, and acute management of this difficult patient population.

Abstract
OBJECTIVES This study aimed to address whether hydroxyethyl starch (HES) is beneficial for intra-abdominal pressure (IAP) in severe acute pancreatitis (SAP) in early stages. METHODS Forty-one patients with SAP were randomized to HES group (n = 20) and the Ringer's lactate (RL) group (n = 21). The groups received 6% HES 130/0.4 for 8 days and RL solution without colloid, respectively. The primary end point was the IAP. The secondary end points were fluid balance, major organ complications, the Acute Physiology and Chronic Heath Evaluation II score, and the serum levels of C-reactive protein, interleukin-6, and interleukin-8. RESULTS The characteristics of baseline data were similar in the 2 groups. In the HES group, the IAP was significantly lower in 2 to 7 days, and fewer patients received mechanical ventilation (15.0% vs 47.6%). A negative fluid balance was observed earlier in the HES group than in the RL group (2.5 ± 2.2 vs 4.0 ± 2.5 days). CONCLUSIONS Fluid resuscitation with HES in the early stages of SAP can decrease the risk of intra-abdominal hypertension and reduce the use of mechanical ventilation.

Abstract
OBJECTIVE Several formulas have been developed to guide resuscitation in severely burned patients during the initial 48 hrs after injury. These approaches require manual titration of fluid that may result in human error during this process and lead to suboptimal outcomes. The goal of this study was to analyze the efficacy of a computerized open-loop decision support system for burn resuscitation compared to historical controls. DESIGN Fluid infusion rates and urinary output from 39 severely burned patients with >20% total body surface area burns were recorded upon admission (Model group). A fluid-response model based on these data was developed and incorporated into a computerized open-loop algorithm and computer decision support system. The computer decision support system was used to resuscitate 32 subsequent patients with severe burns (computer decision support system group) and compared with the Model group. SETTING Burn intensive care unit of a metropolitan Level 1 Trauma center. PATIENTS Acute burn patients with >20% total body surface area requiring active fluid resuscitation during the initial 24 to 48 hours after burn. MEASUREMENTS AND MAIN RESULTS We found no significant difference between the Model and computer decision support system groups in age, total body surface area, or injury mechanism. Total crystalloid volume during the first 48 hrs post burn, total crystalloid intensive care unit volume, and initial 24-hr crystalloid intensive care unit volume were all lower in the computer decision support system group. Infused volume per kilogram body weight (mL/kg) and per percentage burn (mL/kg/total body surface area) were also lower for the computer decision support system group. The number of patients who met hourly urinary output goals was higher in the computer decision support system group. CONCLUSIONS Implementation of a computer decision support system for burn resuscitation in the intensive care unit resulted in improved fluid management of severely burned patients. All measures of crystalloid fluid volume were reduced while patients were maintained within urinary output targets a higher percentage of the time. The addition of computer decision support system technology improved patient care.

Abstract
BACKGROUND Data relating to patients admitted with extensive burn injuries in the Netherlands have revealed a marked increase in patients whose initial care included mechanical ventilation (MV). The increase was abrupt, dating from 1997, and has been sustained since. The aim of this study is to quantify this observation and to discuss possible causes. METHODS The study included 258 consecutive patients with burns >30% total body surface area admitted to the Beverwijk burns center. Patients were divided into two groups based on admission date: group 1 from 1987 to 1996 (n=135) and group 2 from 1997 to 2006 (n=123). Data were analyzed using χ or analysis of variance. RESULTS There were no differences between groups in demographics, facial burns, inhalation injury, and % total body surface area. However, the number of patients subjected to MV at admission increased from 38% to 76% (group 1 vs. 2; p<0.001). In 57% of patients who were intubated based on the suspicion of inhalation injury, this condition could not be confirmed (p<0.05 vs. 9% [1987-1996]). CONCLUSIONS This study has confirmed that a higher proportion of patients were treated with MV since 1997, whereas the severity of burn injury remained unchanged throughout the study period. In the absence of a clinical explanation, we surmise that there has been a change within Dutch casualty departments in the initial management of major burn injury. The change coincides with the implementation of the Advanced Life Trauma Support training course as the accepted standard of trauma care in Dutch hospitals.

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.

BACKGROUND Fluid resuscitation after severe burns remains a challenging task particularly in the preclinical and early clinical phases. To facilitate volume substitution after burn trauma several formulae have been published and evaluated, nevertheless, the optimal formula has not yet been identified. METHODS A systematic PubMed search was performed to identify published formulae for fluid resuscitation after severe burns. The search terms "burn", "thermal", "treatment", "therapy" or "resuscitation", "fluid", "formula" and "adult", "pediatric" or "paediatric" were used in various combinations. Analysis was limited to the period from 01.01.1950 to 30.06.2010 and database entries in PubMed (http://www.pubmed.com). Additionally, references cited in the papers were analyzed and relevant publications were also included. Publications and formulae were assessed and classified by two independent investigators. RESULTS Within the specified time frame eight publications (five original contributions and three book chapters) were identified of which three formulae recommended colloid solutions, four recommended electrolyte solutions and one suggested hypertonic solutions within the first 24 h for fluid resuscitation. Only one formula specifically dealt with fluid resuscitation in infants. CONCLUSION The identified formulae led to sometimes strikingly diverse calculations of resuscitation fluid volumes. Therefore their use should be monitored closely and clinical values included. Urine output is a well established individual parameter. Use of colloid and hypertonic solutions leads to a reduced total fluid volume but is still controversially discussed.

Abstract
Thermal injury is a sad but common and obligatory component of armed conflicts. Although the frequency of noncombat burns has decreased, overall incidence of burns in current military operations has nearly doubled during the past few years. Burn injuries in the military environment do not need to be hostile in nature. Burns resulting from carelessness outnumber those resulting from hostile action. Unfortunately, civilians are becoming the major targets in modern-day conflicts; they account for more than 80% of those killed and wounded in present-day conflicts. The provision of military burn care mirrors the civilian standards; however, several aspects of treatment of war-related burn injuries are peculiar to the war situation itself and to the specific conditions of each armed conflict. Important aspects of management of burned military personnel include triage to ensure that available medical care resources are matched to the severity of burn injury and the number of burn casualties, initial management and resuscitation in the combat zone, and subsequent evacuation to higher echelons of medical care, each with increasing medical capabilities. Care of military victims is usually well structured and follows strict guidelines for first aid and evacuation to field hospitals by military personnel usually having had some form of training in first aid and resuscitation and for which necessary equipment and material for such interventions are more or less available. Options available for civilian injury intervention in wartime, however, are limited. Of all pre-hospital transport of civilian victims, 70% are done by lay public and 93% receive in the field, or during transport, some form of basic first aid administered by relatives, friends, or other first responders not trained for such interventions. Civilian casualties frequently represents 60% to 80% of all injured admitted to the level III facilities of overseas forces stationed throughout the host country. Unlike military personnel who are rapidly evacuated to higher echelons IV and V for definitive and long-term care, civilians must receive definitive burn treatment at these level III military facilities. The present review was intended to highlight peculiar aspects of war-related burn injuries of both military personnel and civilians and their management based on the most recently published material that, for the most part, is related to the recent conflicts in Iraq and Afghanistan.

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.
