Dysnatremias and survival in adult burn patients: a retrospective analysis.

BACKGROUND/AIMS: Dysnatremias have been evaluated in many populations and have been found to be significantly associated with mortality. However, this relationship has not been well described in the burn population. METHODS: Admissions to the burn center at our institution from January 2003 to December 2008 were examined. Independent variables included gender, age, percentage total body surface area burned (%TBSA), percentage of third-degree burn, inhalation injury, injury severity score (ISS), Acute Kidney Injury Network (AKIN) stage, hypernatremia, and hyponatremia. They were examined via Cox proportional hazard regression models against death. Moderate to severe hypo- and hypernatremia were defined as serum sodium <130 and >150 mmol/l, respectively. RESULTS: In 1,969 subjects with a mean age of 36.3 ± 16.4 years, a median %TBSA of 9 (interquartile range 4-20) and a median ISS of 5 (interquartile range 1-16) hypernatremia occurred in 9.9% (n = 194), while hyponatremia occurred in 6.8% (n = 134) with mortality rates of 33.5 and 13.8%, respectively. Patients without a dysnatremia had a mortality rate of 4.3%. On Cox proportional hazard regression age, %TBSA, ISS, and AKIN stage were found to be significant predictors of mortality. Hypernatremia (HR 2.00, 95% CI 1.212-3.31; p = 0.0066), but not hyponatremia (HR 1.72, 95% CI 0.89-3.34; p = 0.1068) was associated with mortality. CONCLUSIONS: In the burn population, hypernatremia, but not hyponatremia, is an independent predictor of mortality.

Silver-coated nylon dressing plus active DC microcurrent for healing of autogenous skin donor sites.

INTRODUCTION: Burn wounds are a significant cause of morbidity and mortality, and improved outcomes are demonstrated with early closure of both primary burn wounds and skin donor sites. Thus, technology that decreases the healing time of burns and donor sites would be potentially lifesaving. We present the results of a single-center, prospective, double-blinded, randomized controlled trial to evaluate the efficacy of silver-coated dressing with active microcurrent in comparison to silver-coated dressing with sham microcurrent on wound-closure time for autogenous skin donor sites. METHODS: Four hundred five patients were screened for treatment of their donor sites using a silver-coated nylon dressing with either sham or active microcurrent stimulation. Thirty patients were enrolled in the study and then randomized. Of these, 5 patients were removed from analysis due to protocol deviations. Differences in time-to-closure were analyzed using Kaplan-Meier analysis and the proportional hazard regression model. Subjective verbal pain rating scores (0-10; 0, no pain; 10, worst pain) were also recorded. All devices were blinded and programmed at an outside facility, so that every patient had either an active or sham device. The study was unblinded only after the final patient's donor site had healed. All patients achieved donor-site healing before postoperative day 20. The 14 patients in the active microcurrent group [mean, 10.8 (2.9) days; range, 7-15 days] experienced no difference in time to wound healing as compared to the remaining patients in the sham microcurrent group [mean, 11.1 (2.0) days; range, 8-14 days; P = 0.75]. There were no differences in pain from one group compared to the other. None of the donor sites exhibited clinical signs of infection. CONCLUSIONS: In a sample size of 25 burn patients, the addition of direct microcurrent to silver-nylon dressings did not decrease time to wound closure of skin donor sites, and it did not show a difference in reported pain levels.

Prehospital burn management in a combat zone.

OBJECTIVE: The purpose of this article is to provide a descriptive study of the management of burns in the prehospital setting of a combat zone. METHODS: A retrospective chart review was performed of U.S. casualties with >20% total-body-surface-area thermal burns, transported from the site of injury to Ibn Sina Combat Support Hospital (CSH) between January 1, 2006, and August 30, 2009. RESULTS: Ibn Sina CSH received 225 burn casualties between January 2006 and August 2009. Of these, 48 met the inclusion criteria. The mean Injury Severity Score was 31.7 (range 4 to 75). Prehospital vascular access was obtained in 24 casualties (50%), and 20 of the casualties received fluid resuscitation. Out of the 48 casualties enrolled, 28 (58.3%) did not receive prehospital fluid resuscitation. Of the casualties who received fluid resuscitation, nearly all received volumes in excess of the guidelines established by the American Burn Association and those recommended by the Committee for Tactical Combat Casualty Care. With regard to pain management in the prehospital setting, 13 casualties (27.1%) received pain medication. CONCLUSIONS: With regard to the prehospital fluid resuscitation of primary thermal injury in the combat zone, two extremes were noted. The first group did not receive any fluid resuscitation; the second group was resuscitated with fluid volumes higher than those expected if established guidelines were utilized. Pain management was not uniformly provided to major burn casualties, even in several with vascular access. These observations support improved education of prehospital personnel serving in a combat zone.

Saksenaea erythrospora infection following combat trauma.

Saksenaea erythrospora is a newly described species of the order Mucorales which has not previously been reported as a cause of human infection. We report a fatal case of S. erythrospora invasive burn wound infection in a 26-year-old male injured during combat operations in Iraq.

Pythium aphanidermatum infection following combat trauma.

Pythium aphanidermatum is a fungus-like plant pathogen which has never been reported as a cause of human infection. We report a case of P. aphanidermatum invasive wound infection in a 21-year-old male injured during combat operations in Afghanistan.

Computerized decision support system improves fluid resuscitation following severe burns: an original study.

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.

Prevention of infections associated with combat-related burn injuries.

Burns are a very real component of combat-related injuries, and infections are the leading cause of mortality in burn casualties. The prevention of infection in the burn casualty transitioning from the battlefield to definitive care provided at the burn center is critical in reducing overall morbidity and mortality. This review highlights evidence-based medicine recommendations using military and civilian data to provide the most comprehensive, up-to-date management strategies for initial care of burned combat casualties. Areas of emphasis include antimicrobial prophylaxis, debridement of devitalized tissue, topical antimicrobial therapy, and optimal time to wound coverage. This evidence-based medicine review was produced to support the Guidelines for the Prevention of Infections Associated With Combat-Related Injuries: 2011 Update contained in this supplement of Journal of Trauma.

Use of ultra rapid opioid detoxification in the treatment of US military burn casualties.

BACKGROUND: The purpose of this case series was to review the management of burn patients who requested ultrarapid opioid detoxification under anesthesia after extended duration of narcotic use for chronic pain related to burn injury. METHODS: The treatment plan of six opioid-dependent burn patients was analyzed to assess the effectiveness of our detoxification practice to date. Demographic and clinical information was used to characterize the patient population served: age, burn size, injury severity, duration of narcotic use before detoxification intervention, and length of hospitalization stay. Daily narcotic consumption, in morphine equivalent units, was noted both before and after detoxification. RESULTS: Six burn patients (average age, 31 years) underwent detoxification at the Burn Center during a hospitalization lasting between 1 day and 2 days. Average burn size was 38% total body surface area (range, 17-65); average Injury Severity Score was 30 (range, 25-38). Mean duration of narcotic use was 672 days (range, 239-1,156 days); average use of narcotics at time of detoxification was >200 units daily. Mean outpatient consumption for opioids after the intervention was minimal (<25 units/d). No complications were noted during any procedures. CONCLUSIONS: The results of ultrarapid opioid detoxification under anesthesia suggests that it is safe and effective for treating opioid addiction in military burn casualties when a coordinated, multidisciplinary approach is used. Safety and effectiveness to date validate current practice and supports incorporation into clinical practice guidelines. Further clinical research is warranted to identify those patients who may benefit most from detoxification and to determine the timing of such treatment.

Executive summary: Guidelines for the prevention of infections associated with combat-related injuries: 2011 update: endorsed by the Infectious Diseases Society of America and the Surgical Infection Society.

Despite advances in resuscitation and surgical management of combat wounds, infection remains a concerning and potentially preventable complication of combat-related injuries. Interventions currently used to prevent these infections have not been either clearly defined or subjected to rigorous clinical trials. Current infection prevention measures and wound management practices are derived from retrospective review of wartime experiences, from civilian trauma data, and from in vitro and animal data. This update to the guidelines published in 2008 incorporates evidence that has become available since 2007. These guidelines focus on care provided within hours to days of injury, chiefly within the combat zone, to those combat-injured patients with open wounds or burns. New in this update are a consolidation of antimicrobial agent recommendations to a backbone of high-dose cefazolin with or without metronidazole for most postinjury indications and recommendations for redosing of antimicrobial agents, for use of negative pressure wound therapy, and for oxygen supplementation in flight.

High-frequency percussive ventilation and low tidal volume ventilation in burns: a randomized controlled trial.

OBJECTIVES: In select burn intensive care units, high-frequency percussive ventilation is preferentially used to provide mechanical ventilation in support of patients with acute lung injury, acute respiratory distress syndrome, and inhalation injury. However, we found an absence of prospective studies comparing high-frequency percussive ventilation with contemporary low-tidal volume ventilation strategies. The purpose of this study was to prospectively compare the two ventilator modalities in a burn intensive care unit setting. DESIGN: Single-center, prospective, randomized, controlled clinical trial, comparing high-frequency percussive ventilation with low-tidal volume ventilation in patients admitted to our burn intensive care unit with respiratory failure. SETTING: A 16-bed burn intensive care unit at a tertiary military teaching hospital. PATIENTS: Adult patients ≥ 18 yrs of age requiring prolonged (> 24 hrs) mechanical ventilation were admitted to the burn intensive care unit. The study was conducted over a 3-yr period between April 2006 and May 2009. This trial was registered with ClinicalTrials.gov as NCT00351741. INTERVENTIONS: Subjects were randomly assigned to receive mechanical ventilation through a high-frequency percussive ventilation-based strategy (n = 31) or a low-tidal volume ventilation-based strategy (n = 31). MEASUREMENTS AND MAIN RESULTS: At baseline, both the high-frequency percussive ventilation group and the low-tidal volume ventilation group had similar demographics to include median age (interquartile range) (28 yrs [23-45] vs. 33 yrs [24-46], p = nonsignificant), percentage of total body surface area burn (34 [20-52] vs. 34 [23-50], p = nonsignificant), and clinical diagnosis of inhalation injury (39% vs. 35%, p = nonsignificant). The primary outcome was ventilator-free days in the first 28 days after randomization. Intent-to-treat analysis revealed no significant difference between the high-frequency percussive ventilation and the low-tidal volume ventilation groups in mean (± sd) ventilator-free days (12 ± 9 vs. 11 ± 9, p = nonsignificant). No significant difference was detected between groups for any of the secondary outcome measures to include mortality except the need for "rescue" mode application (p = .02). Nine (29%) in the low-tidal volume ventilation arm did not meet predetermined oxygenation or ventilation goals and required transition to a rescue mode. By contrast, two in the high-frequency percussive ventilation arm (6%) required rescue. CONCLUSIONS: A high-frequency percussive ventilation-based strategy resulted in similar clinical outcomes when compared with a low-tidal volume ventilation-based strategy in burn patients with respiratory failure. However, the low-tidal volume ventilation strategy failed to achieve ventilation and oxygenation goals in a higher percentage necessitating rescue ventilation.

Outcomes with the use of recombinant human erythropoietin in critically ill burn patients.

Recent data demonstrate a possible mortality benefit in traumatically injured patients when given subcutaneous recombinant human erythropoietin (rhEPO). The purpose of this report is to examine the effect of rhEPO on mortality and transfusion in burn patients. We conducted a review of burn patients (greater than 30% total body surface area, intensive care unit [ICU] days greater than 15) treated with 40,000 u rhEPO over an 18-month period (January 2007 to July 2008). Matched historical controls were identified and a contemporaneous cohort of subjects not administered rhEPO was used for comparison (NrhEPO). Mortality, transfusions, ICU and hospital length of stay were assessed. A total of 105 patients were treated (25 rhEPO, 53 historical control group, 27 NrhEPO). Hospital transfusions (mean 13,704 +/- mL vs. 13,308 +/- mL; P = 0.42) and mortality (29.6 vs. 32.0%; P = 0.64) were similar. NrhEPO required more blood transfusions (13,308 +/- mL vs. 6827 +/- mL; P = 0.004). No difference in mortality for the rhEPO and NrhEPO (32.0 vs. 22.2%; P = 0.43) was found. Thromboembolic complications were similar in all three groups. No effect was seen for rhEPO treatment on mortality or blood transfusion requirements in the severely burned.

Simple derivation of the initial fluid rate for the resuscitation of severely burned adult combat casualties: in silico validation of the rule of 10.

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.

Predictors of early acute lung injury at a combat support hospital: a prospective observational study.

BACKGROUND: Acute lung injury (ALI) is a syndrome consisting of noncardiogenic acute hypoxemic respiratory failure with the presence of bilateral pulmonary infiltrates and occurs in up to 33% of critically ill trauma patients. Retrospective and observational studies have suggested that a blood component resuscitation strategy using equal ratios of packed red blood cells (PRBCs) and fresh frozen plasma (FFP) may have a survival benefit in combat casualties. The purpose of this study was to determine whether this strategy is associated with an increased incidence of ALI. METHODS: We performed a prospective observational study of all injured patients admitted to an intensive care unit (ICU) at a combat support hospital who required >5 units of blood transfusion within the first 24 hours of admission. Baseline demographic data along with Injury Severity Score (ISS), pulmonary injury, presence of long bone fracture, blood products transfused, mechanical ventilation data, and arterial blood gas analysis were collected. The primary endpoint of the study was the development of ALI at 48 hours after injury. Those who did not survive to ICU admission were excluded from analysis. Follow-up (including mortality) longer than 48 hours was unavailable secondary to rapid transfer out of our facility. A multivariate logistic regression was performed to determine the independent effects of variables on the incidence of early ALI. RESULTS: During a 12-month period (from January 2008 to December 2008), 87 subjects were studied; of these, 66 patients met inclusion criteria, and 22 patients developed ALI at 48 hours (33%). Overall, the ratio of FFP to PRBC was 1:1.1. Those who developed ALI had a higher ISS (32 +/- 15 vs. 26 +/- 11; p = 0.04) and received more units of FFP (22 +/- 15 vs. 12 +/- 7; p < 0.001), PRBCs (22 +/- 16 vs. 13 +/- 7; p = 0.008), and platelets (5 +/- 11 vs. 1 +/- 2; p = 0.004) compared with those who did not develop ALI. Multivariate logistic regression analysis revealed that presence of pulmonary injury (odds ratio, 5.4; 95% confidence interval, 1.3-21.9) and volume of FFP transfused (odds ratio, 1.2; 95% confidence interval, 1.1-1.3) had independent effects on ALI at 48 hours. CONCLUSION: On the basis of this small, prospective, descriptive study of severely injured patients admitted to the ICU, we determined that the presence of pulmonary injury had the greatest impact on the incidence of early ALI. There was also an independent relationship between the amount of FFP transfused and the incidence of early ALI. Further studies are required to determine the effects of the development of early ALI from FFP transfusion on short- and long-term survival.

Fenoldopam use in a burn intensive care unit: a retrospective study.

BACKGROUND: Fenoldopam mesylate is a highly selective dopamine-1 receptor agonist approved for the treatment of hypertensive emergencies that may have a role at low doses in preserving renal function in those at high risk for or with acute kidney injury (AKI). There is no data on low-dose fenoldopam in the burn population. The purpose of our study was to describe our use of low-dose fenoldopam (0.03-0.09 mug/kg/min) infusion in critically ill burn patients with AKI. METHODS: We performed a retrospective analysis of consecutive patients admitted to our burn intensive care unit (BICU) with severe burns from November 2005 through September 2008 who received low-dose fenoldopam. Data obtained included systolic blood pressure, serum creatinine, vasoactive medication use, urine output, and intravenous fluid. Patients on concomitant continuous renal replacement therapy were excluded. Modified inotrope score and vasopressor dependency index were calculated. One-way analysis of variance with repeated measures, Wilcoxson signed rank, and chi-square tests were used. Differences were deemed significant at p < 0.05. RESULTS: Seventy-seven patients were treated with low-dose fenoldopam out of 758 BICU admissions (10%). Twenty (26%) were AKI network (AKIN) stage 1, 14 (18%) were AKIN stage 2, 42 (55%) were AKIN stage 3, and 1 (1%) was AKIN stage 0. Serum creatinine improved over the first 24 hours and continued to improve through 48 hours (p < 0.05). There was an increase in systolic blood pressure in the first 24 hours that was sustained through 48 hours after initiation of fenoldopam (p < 0.05). Urine output increased after initiation of fenoldopam without an increase in intravenous fluid requirement (p < 0.05; p = NS). Modified inotrope score and vasopressor dependency index both decreased over 48 hours (p < 0.0001; p = 0.0012). CONCLUSIONS: These findings suggest that renal function was preserved and that urine output improved without a decrease in systolic blood pressure, increase in vasoactive medication use, or an increase in resuscitation requirement in patients treated with low-dose fenoldopam. A randomized controlled trial is required to establish the efficacy of low-dose fenoldopam in critically ill burn patients with AKI.

Infectious complications of noncombat trauma patients provided care at a military trauma center.

Infectious complications are reported frequently in combat trauma patients treated at military hospitals. Infections in 4566 noncombat related trauma patients treated at a military trauma center were retrospectively reviewed from 1/2003 to 5/2007 using registry data. Burns, penetrating, and blunt trauma accounted for 17%, 19%, and 64%, respectively; the median age was 38 and 22% were female. Pulmonary infections were present in 4.2% of patients, 2.4% had cellulitis and wound infections, 2.2% urinary infections, and 0.7% sepsis. On univariate analysis, infected patients were more likely to be admitted to the ICU, have longer ICU and hospital lengths of stay (LOS), and to die (p < 0.05). Multivariate analysis revealed associations between infection and hospital LOS, preexisting medical conditions, and lower Glasgow Coma Scale in nonburned patients. In burned patients, infection was associated with total body surface area burned and preexisting conditions (p < 0.01). Enhanced infection control in targeted trauma populations may improve outcomes.

Continuous venovenous hemofiltration in severely burned patients with acute kidney injury: a cohort study.

INTRODUCTION: Acute kidney injury (AKI) is a common and devastating complication in critically ill burn patients with mortality reported to be between 80 and 100%. We aimed to determine the effect on mortality of early application of continuous venovenous hemofiltration (CVVH) in severely burned patients with AKI admitted to our burn intensive care unit (BICU). METHODS: We performed a retrospective cohort study comparing a population of patients managed with early and aggressive CVVH compared with historical controls managed conservatively before the availability of CVVH. Patients with total body surface area (TBSA) burns of more than 40% and AKI were treated with early CVVH and their outcomes compared with a group of historical controls. RESULTS: Overall, the 28-day mortality was significantly lower in the CVVH arm (n = 29) compared with controls (n = 28) (38% vs. 71%, P = 0.011) as was the in-hospital mortality (62% vs. 86%, P = 0.04). In a subgroup of patients in shock, a dramatic reduction in the pressor requirement was seen after 24 and 48 hours of treatment. Compared with controls (n = 19), significantly fewer patients in the CVVH group (n = 21) required vasopressors at 24 hours (100% vs 43%, P < 0.0001) and at 48 hours (94% vs 24%, P < 0.0001). In those with acute lung injury (ALI)/acute respiratory distress syndrome (ARDS), there was a significant increase from baseline in the partial pressure of arterial oxygen (PaO2) to fraction of inspired oxygen (FiO2) ratio at 24 hours in the CVVH group (n = 16, 174 +/- 78 to 327 +/- 122, P = 0.003) but not the control group (n = 20, 186 +/- 64 to 207 +/- 131, P = 0.98). CONCLUSIONS: The application of CVVH in adult patients with severe burns and AKI was associated with a decrease in 28-day and hospital mortality when compared with a historical control group, which largely did not receive any form of renal replacement. Clinical improvements were realized in the subgroups of patients with shock and ALI/ARDS. A randomized controlled trial comparing early CVVH to standard care in this high-risk population is planned.

Resuscitation of severely burned military casualties: fluid begets more fluid.

BACKGROUND: In November 2005, institution of a military-wide burn resuscitation guideline requested the documentation of the initial 24-hour resuscitation of severely burned military casualties on a burn flow sheet to provide continuity of care. The guidelines instruct the providers to calculate predicted 24-hour fluid requirements and initial fluid rate based on the American Burn Association Consensus recommendation of 2 (modified Brooke) mL x kg(-1) x % total body surface area (TBSA)(-1) to 4 (Parkland) mL x kg(-1) x %TBSA(-1) burn. The objective of this study was to evaluate the relationship between the estimated fluid volumes calculated, either by the Modified Brooke or the Parkland formulas, and actual volumes received. METHODS: From November 2005 to December 2008, 105 patients were globally evacuated with >20% TBSA burns, of whom 73 had burn flow sheets initiated. Of these, 58 had completed burn flow sheets. Total fluids administered in the first 24-hour period for each patient were recorded. Chart reviews were performed to extract demographic and clinical outcomes data. RESULTS: Of the 58, the modified Brooke formula was used in 31 patients (modified Brooke group) to estimate 24-hour fluid requirements and the Parkland formula was used in 21 (Parkland group). In six, 3 mL x kg(-1) x %TBSA(-1) was used and were excluded from analysis. No significant difference was detected between the two groups for age, %TBSA burned, inhalation injury, or Injury Severity Score. Actual 24-hour resuscitation in the modified Brooke group was significantly lower than in the Parkland group (16.9 L +/- 6.0 L vs. 25.0 L +/- 11.2 L, p = 0.003). A greater percentage of patients exceeded the Ivy index (250 mL/kg) in the Parkland group compared with the modified Brooke group (57% vs. 29%, p = 0.026). On average, those who had 24-hour fluid needs estimated by the modified Brooke formula received a 3.8 mL x kg(-1) x %TBSA(-1) +/- 1.2 mL x kg(-1) x %TBSA(-1) resuscitation, whereas the Parkland group received a 5.9 mL x kg(-1) x %TBSA(-1) +/- 1.1 mL x kg(-1) x %TBSA(-1) resuscitation (p < 0.0001). No differences in measured outcomes were detected between the two groups. On multivariate logistic regression, exceeding the Ivy index was an independent predictor of death (area under the curve [AUC], 0.807; CI, 0.66-0.95). CONCLUSION: In severely burned military casualties undergoing initial burn resuscitation, the modified Brooke formula resulted in significantly less 24-hour volumes without resulting in higher morbidity or mortality.

Advances in surgical care: management of severe burn injury.

BACKGROUND: Management of combat casualties with severe burns and associated traumatic injuries requires a coordinated interaction of surgical, critical care, and evacuation assets. These patients present enormous challenges to the entire medical system as a result of the severity of injury combined with the great distance required for transport to definitive care. OBJECTIVE: The objective of this study was to review and highlight some of the advances in burn critical care experienced during recent combat operations. This review focuses on initial resuscitation, respiratory support, care of the burn wound, and long range evacuation. DATA SOURCE: The authors conducted a search of the MEDLINE database and manual review of published articles and abstracts from national and international meetings in addition to Institute of Surgical Research Burn Center registry. CONCLUSIONS: Fluid resuscitation during the first 24 to 48 hrs after injury remains a significant challenge for all who manage burn casualties. Guidelines have been developed in an effort to standardize fluid resuscitation during this time. These guidelines along with the standardization of burn wound care and continued provider education have resulted in decreased morbidity and mortality in severely burned patients returning from war zones. This system of care for severely burned patients facilitates the transfer of the burn casualty between healthcare providers and facilities and is now being integrated into the catchment area for the Institute of Surgical Research Burn Center.
