Influence of prehospital volume replacement on outcome in polytraumatized children

IntroductionSevere bleeding after trauma frequently results in poor outcomes in children. Prehospital fluid replacement therapy is regarded as an important primary treatment option. Our study aimed, through a retrospective analysis of matched pairs, to assess the influence of prehospital fluid replacement therapy on the post-traumatic course of severely injured children.MethodsThe data for 67,782 patients from the TraumaRegister DGU® of the German Trauma Society were analyzed. The following inclusion criteria were applied: injury severity score ≥16 points, primary admission, age 1 to 15 years old, systolic blood pressure ≥20 mmHg at the accident site and transfusion of at least one unit of packed red blood cells (pRBC) in the emergency trauma room prior to intensive care admission. As volume replacement therapy depends on age and body weight, especially in children, three subgroups were formed according to the mean value of the administered prehospital volume. The children were matched and enrolled into two groups according to the following criteria: intubation at the accident site (yes/no), Abbreviated Injury Scale (four body regions), accident year, systolic blood pressure and age group.ResultsA total of 31 patients in each group met the inclusion criteria. An increase in volume replacement was associated with an elevated need for a transfusion (≥10 pRBC: low volume, 9.7%; high volume, 25.8%; P = 0.18) and a reduction in the ability to coagulate (prothrombin time ratio: low volume, 58.7%; high volume, 55.6%; P = 0.23; prothrombin time: low volume, 42.2 seconds; high volume, 50.1 seconds; P = 0.38). With increasing volume, the mortality (low volume, 19.4%; high volume, 25.8%; P = 0.75) and multiple organ failure rates (group 1, 36.7%; group 2, 41.4%; P = 0.79) increased. With increased volume, the rescue time also increased (low volume, 62 minutes; high volume, 71.5 minutes; P = 0.21).ConclusionFor the first time, a tendency was shown that excessive prehospital fluid replacement in children leads to a worse clinical course with higher mortality and that excessive fluid replacement has a negative influence on the ability to coagulate.

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.

Review article: Prehospital fluid management in traumatic brain injury

The early management of patients who have sustained traumatic brain injury is aimed at preventing secondary brain injury through avoidance of cerebral hypoxia and hypoperfusion. Especially in hypotensive patients, it has been postulated that hypertonic crystalloids and colloids might support mean arterial pressure more effectively by expanding intravascular volume without causing problematic cerebral oedema. We conducted a systematic review to investigate if hypertonic saline or colloids result in better outcomes than isotonic crystalloid solutions, as well as to determine the safety of minimal volume resuscitation, or delayed versus immediate fluid resuscitation during prehospital care for patients with traumatic brain injury. We identified nine randomized controlled trials and one cohort study examined the effects of hypertonic solutions (with or without colloid added) for prehospital fluid resuscitation. None has reported better survival and functional outcomes over the use of isotonic crystalloids. The only trial of restrictive resuscitation strategies was underpowered to demonstrate its safety compared with aggressive early fluid resuscitation in head injured patients, and maintenance of cerebral perfusion remains the top priority.

Current Use of Damage-Control Laparotomy, Closure Rates, and Predictors of Early Fascial Closure at the First Take-Back

Damage-control laparotomy (DCL) is a lifesaving technique but carries significant morbidity. If DCL is over used and the factors that predict early fascial closure have not been fully evaluated. The purpose of the current study was to determine (1) the current rate of DCL, (2) the percentage of DCLs that are closed at first take-back, and (3) possible physiologic and resuscitative parameters predicting early fascial closure. A retrospective review of all trauma laparotomies from a Level I trauma center between January 2004 and December 2008 was performed. Patients were excluded if they died before first take-back. Univariate and multivariate analyses were performed. Nine hundred thirty patients were eligible, 278 (30%) underwent DCL, 36 excluded for death before first take-back. Of the remaining 242 DCL patients, 83 (34%) were closed at first take-back and 159 (66%) were not closed at first take-back. These two groups were similar in injury severity, demographics, and prehospital and emergency department fluids and vitals. Median emergency department international normalized ratio (INR; 1.13 vs. 1.29, p = 0.010), post-op INR (1.4 vs. 1.5, p = 0.028), 24-hour fluids (11.9 L vs. 15.5 L, p = 0.006), peak post-op intra-abdominal pressure (IAP; 15 vs. 18, p < 0.001), and mortality (1.2% vs. 8.2%, p = 0.027) were different between groups. Multivariate analysis noted vacuum-assisted closure at initial laparotomy (Odds ratio, 3.1; 95% confidence interval [CI], 1.42-6.63; p = 0.004) was an independent predictor of closure at first take-back. However, post-op INR (Odds ratio, 0.18; 95% CI, 0.03-0.97; p = 0.04) and post-op peak IAP (Odds ratio, 0.85; 95% CI, 0.76-0.95; p = 0.005) predicted failure to close fascia at first take-back. In similarly injured DCL patients, increased post-op INR and IAP predicted inability to achieve primary fascial closure on first take-back, while use of the vacuum-assisted closure was associated with increased likelihood of early fascial closure. At a busy academic Level I trauma center, the current rate of DCL among those undergoing emergent laparotomy is 30%. Whether this represents optimal use or overutilization of this technique still needs to be determined.

The Alfred pre-hospital fluid formula for major burns

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

State of the Art of Fluid Resuscitation 2010: Prehospital and Immediate Transition to the Hospital

Abstract : The Prehospital Fluid Conference was sponsored by the US Army Institute of Surgical Research and Combat Casualty Care Research, US Army Medical Research and Materiel Command. Some 65 conferees were invited in January 2010 to review the contemporary guidelines on the use of fluid resuscitation in treating combat casualties, discuss the state of the art of fluid resuscitation for combat casualties, and answer the following questions: - Are current Tactical Combat Casualty Care (TCCC) intravenous (IV) fluid resuscitation guidelines optimal for today? - Which IV fluid should be the top priority for future research? - What are the current indications for fluid resuscitation in the combat trauma patient? - What is the current practice in tactical fluid resuscitation? The objective of this conference was to identify the fluid to be used by the prehospital provider and not to address the needs once definitive hemorrhage control has been achieved. The fluids to be used are those that will be carried into the field on the back of the combat medic or in the vehicle used to transport the medic or the patient (echelon 1 care). There are several definitions of these echelons of care (North Atlantic Treaty Organization [NATO], European forces, etc.). The definitions used in this document are those of the Joint Theater Trauma System. The use of role and echelon can be interchangeable depending on the country of origin, but the terms can vary significantly. Echelon, as used in many/most of Joint Theater Trauma System presentations will be used throughout this document to indicate a level of care facility (see Table 1). Although discussions focused on military needs, it was understood and accepted by the consensus group that many, if not all, of the recommendations could and would be used for civilian prehospital providers with appropriate situational modifications.

Foreword—Combat Prehospital Resuscitation

Abstract : Considering the spectrum of combat casualty care, from point of wounding to rehabilitation, prehospital treatment technology has not kept pace with advances in other areas. When responding to the most common cause of potentially survivable but often fatal injury (penetrating truncal trauma),1,2 the medic on today s battlefield has treatment options that are defined by currently available technology. Penetrating truncal injury is often associated with noncompressible torso hemorrhage, the initial management of which is limited to the replacement of intravascular volume in an attempt to avoid ischemia and exsanguination before surgical hemostasis. The importance of injury-induced hypovolemia and the current technological limitations of prehospital resuscitation necessitate the reappraisal of resuscitative fluid strategies that was conducted during this conference. Almost a decade has passed since the last civilian-military fluid conference, and our goal with this symposium is to review data on any new potential fluids, which may offer an advantage over those currently in use. An additional objective of this conference is to aid in the refinement and focus of ongoing research efforts in this field. As the consensus conclusions of this symposium will reveal, freeze-dried plasma (FDP) may be the next generation of improved resuscitation fluids. Although the US Military infused FDP in World War II on the beaches of Normandy, the military does not have this option available today. In the context of this paradox, prehospital fluid replacement with FDP may represent a trip back to the future in the cause of improving the care of the combat casualty.

Prehospital Intravenous Fluid Administration Is Associated With Higher Mortality in Trauma Patients

Prehospital intravenous (IV) fluid administration is common in trauma patients, although little evidence supports this practice. We hypothesized that trauma patients who received prehospital IV fluids have higher mortality than trauma patients who did not receive IV fluids in the prehospital setting. We performed a retrospective cohort study of patients from the National Trauma Data Bank. Multiple logistic regression was used with mortality as the primary outcome measure. We compared patients with versus without prehospital IV fluid administration, using patient demographics, mechanism, physiologic and anatomic injury severity, and other prehospital procedures as covariates. Subset analysis was performed based on mechanism (blunt/penetrating), hypotension, immediate surgery, severe head injury, and injury severity score. A total of 776,734 patients were studied. Approximately half (49.3%) received prehospital IV. Overall mortality was 4.6%. Unadjusted mortality was significantly higher in patients receiving prehospital IV fluids (4.8% vs. 4.5%, P < 0.001). Multivariable analysis demonstrated that patients receiving IV fluids were significantly more likely to die (odds ratio [OR] 1.11, 95% confidence interval [CI] 1.05–1.17). The association was identified in nearly all subsets of trauma patients. It is especially marked in patients with penetrating mechanism (OR 1.25, 95% CI 1.08–1.45), hypotension (OR 1.44, 95% CI1.29–1.59), severe head injury (OR 1.34, 95% CI 1.17–1.54), and patients undergoing immediate surgery (OR 1.35, 95% CI 1.22–1.50). The harm associated with prehospital IV fluid administration is significant for victims of trauma. The routine use of prehospital IV fluid administration for all trauma patients should be discouraged.

Influence of prehospital fluid resuscitation on patients with multiple injuries in hemorrhagic shock in patients from the DGU trauma registry

Background:Severe bleeding as a result of trauma frequently leads to poor outcome by means of direct or delayed mechanisms. Prehospital fluid therapy is still regarded as the main option of primary treatment in many rescue situations. Our study aimed to assess the influence of prehospital fluid replacement on the posttraumatic course of severely injured patients in a retrospective analysis of matched pairs.Materials and Methods:We reviewed data from 35,664 patients recorded in the Trauma Registry of the German Society for Trauma Surgery (DGU). The following patients were selected: patients having an Injury Severity Score >16 points, who were ≥16 years of age, with trauma, excluding those with craniocerebral injuries, who were admitted directly to the participating hospitals from the accident site. All patients had recorded values for replaced volume and blood pressure, hemoglobin concentration, and units of packed red blood cells given. The patients were matched based on similar blood pressure characteristics, age groups, and type of accident to create pairs. Pairs were subdivided into two groups based on the volumes infused prior to hospitalization: group 1: 0-1500 (low), group 2: ≥2000 mL (high) volume.Results:We identified 1351 pairs consistent with the inclusion criteria. Patients in group 2 received significantly more packed red blood cells (group 1: 6.9 units, group 2: 9.2 units; P=0.001), they had a significantly reduced capacity of blood coagulation (prothrombin ratio: group 1: 72%, group 2: 61.4%; P≤0.001), and a lower hemoglobin value on arrival at hospital (group 1: 10.6 mg/dL, group 2: 9.1 mg/dL; P≤0.001). The number of ICU-free days concerning the first 30 days after trauma was significantly higher in group 1 (group 1: 11.5 d, group 2: 10.1 d; P≤0.001). By comparison, the rate of sepsis was significantly lower in the first group (group 1: 13.8%, group 2: 18.6%; P=0.002); the same applies to organ failure (group 1: 36.0%, group 2: 39.2%; P≤0.001).Conclusion:The high amounts of intravenous fluid replacement was related to early traumatic coagulopathy, organ failure, and sepsis rate.

Noncolligative properties of intravenous fluids

Currently available crystalloids were designed over a century ago for dehydration and not for the treatment of hemorrhagic shock. Information regarding fluids used for resuscitation has grown and thus resuscitation has changed radically in the last two decades. Artificial fluids such as crystalloids and other solutions typically used for resuscitation are now recognized to be inflammatory when infused at high volumes to replace blood. Recent studies have shown that the crystalloids and artificial colloids cause inflammation. Prehospital fluid use has not shown to be of benefit and permissive hypotension may be useful. Careful titration of fluids with minimizing crystalloids and early use of blood products have improved outcome after traumatic hemorrhagic shock. Seemingly innocuous fluids have a dose effect and can be detrimental. Crystalloids can create inflammation when used at high volumes and may be the reason for the sequelae seen after massive resuscitation. This has led to the recognition that whole blood is extremely complex and does much more than carry oxygen. Resuscitation has changed recently with the adoption of damage control resuscitation which is the practice of allowing permissive hypotension, minimizing crystalloids and early aggressive use of blood products. This has led to a decrease in multiple organ dysfunction syndrome and acute respiratory distress syndrome.

Hemoglobin-based Oxygen Carrier (HBOC-201) and Escalating Doses of Recombinant Factor VIIa (rFVIIa) as a Novel Pre-hospital Resuscitation Fluid in a Swine Model of Severe Uncontrolled Hemorrhage

Exsanguinating hemorrhage and unavailability of blood are major problems in pre-hospital trauma care. We investigated if combining rFVIIa with HBOC-201 reduces blood loss and improves physiologic parameters compared to HBOC alone. Swine underwent liver injury and were resuscitated with HBOC-201 alone or HBOC+90, 180 or 360 μg/kg rFVIIa before hospital arrival at 240 min; animals survived to 72 hours. Blood loss was reduced; MAP, CI, transcutaneous oxygen saturation, and 72-hour survival improved in the 90 and 180 μg/kg rFVIIa groups. Lactate was cleared faster in the HBOC+rFVIIa 90 μg/kg group. Verification in a large, well-powered study is indicated.

Resuscitation of traumatic brain injury and hemorrhagic shock with polynitroxylated albumin, hextend, hypertonic saline, and lactated Ringer's: Effects on acute hemodynamics, survival, and neuronal death in mice.

Outcome after traumatic brain injury (TBI) is worsened by hemorrhagic shock (HS), but the optimal resuscitation approach is unclear. In particular, treatment of TBI patients with colloids remains controversial. We hypothesized that resuscitation with the colloids polynitroxylated albumin (PNA) or Hextend (HEX) is equal or superior to resuscitation with the crystalloids hypertonic (3%) saline (HTS) or lactated Ringer's solution (LR) after TBI plus HS in mice. C57/BL6 mice (n = 30) underwent controlled cortical impact (CCI) and 90 min of volume-controlled HS (2 mL/100 g). The mice were randomized to resuscitation with LR, HEX, HTS, or PNA, followed by 30 min of test fluid administration targeting a mean arterial pressure (MAP) of >50 mm Hg. Shed blood was re-infused to target a MAP >70 mm Hg. At 7 days post-insult, hippocampal neuron counts were assessed in hematoxylin and eosin-stained sections to quantify neuronal damage. Prehospital MAP was higher, and prehospital and total fluid requirements were lower in the PNA and HEX groups (p < 0.05 versus HTS or LR). Also, 7-day survival was highest in the PNA group, but was not significantly different than the other groups. Ipsilateral hippocampal CA1 and CA3 neuron loss did not differ between groups. We conclude that the colloids PNA and HEX exhibited more favorable effects on acute resuscitation parameters than HTS or LR, and did not increase hippocampal neuronal death in this model.

Guidelines for Prehospital Fluid Resuscitation in the Injured Patient

Although the need and benefit of prehospital interventions has been controversial for quite some time, an increasing amount of evidence has stirred both sides into more frequent debate. Proponents of the traditional "scoop-and-run" technique argue that this approach allows a more timely transfer to definitive care facilities and limits unnecessary (and potentially harmful) procedures. However, advocates of the "stay-and-play" method point to improvement in survival to reach the hospital and better neurologic outcomes after brain injury. Given the lack of consensus, the Eastern Association for the Surgery of Trauma convened a Practice Management Guideline committee to answer the following questions regarding prehospital resuscitation: (1) should injured patients have vascular access attempted in the prehospital setting? (2) if so, what location is preferred for access? (3) if access is achieved, should intravenous fluids be administered? (4) if fluids are to be administered, which solution is preferred? and (5) if fluids are to be administered, what volume and rate should be infused?

Hematologic effects of recombinant factor VIIa combined with hemoglobin-based oxygen carrier-201 for prehospital resuscitation of swine with severe uncontrolled hemorrhage due to liver injury

The combination of traumatic injury, hemorrhage, and fluid resuscitation results in consumption and dilution of coagulation factors, adversely impacting hematology outcome in trauma patients. The hemostatic effects of escalating doses of recombinant factor VIIa added to hemoglobin-based oxygen carrier-201 were assessed as prehospital fluid resuscitation in swine with severe uncontrolled hemorrhage. Swine underwent liver injury causing severe uncontrolled hemorrhage and shock. During a 4-h prehospital phase, either hypotensive or tachycardic, or both, animals were resuscitated with hemoglobin-based oxygen carrier-201 without (0x) or with escalating doses of recombinant factor VIIa [90 microg/kg (1x), 180 microg/kg (2x), or 360 microg/kg (4x)]. The animals received one initial full dose of 10 ml/kg at 15 min and up to four doses of 5 ml/kg thereafter. From 4 to 72 h (hospital phase), animals received either transfusions or isotonic saline or both as needed. Hematology profile (complete blood count), thromboelastography, in-vitro bleeding (platelet function analyzer), and coagulation (prothrombin time) were measured and the results were compared using mixed statistical models. In all groups, dilutional coagulopathy was evidenced by reduced hematocrit, platelets, and thromboelastography-maximum amplitude, and increased platelet function analyzer closure time and thromboelastography-reaction time. During the prehospital phase, hemoglobin-based oxygen carrier-201 restored hemoglobin in all groups. Recombinant factor VIIa decreased prothrombin time in recombinant factor VIIa groups compared with the hemoglobin-based oxygen carrier-201 group (P < 0.01). Unexpectedly, increasing recombinant factor VIIa dosage tended to increase fluid requirement (P > 0.05). Compared with hemoglobin-based oxygen carrier, 1x recombinant factor VIIa tended to decrease blood loss, lactate and thromboelastography-reaction time at 24 h but the 4x group increased these parameters. Platelets and thromboelastography-maximum amplitude decreased (P < 0.01) with the 4x group. In swine with severe uncontrolled hemorrhage, prehospital resuscitation with escalating doses of recombinant factor VIIa in combination with hemoglobin-based oxygen carrier-201 did not change survival or hemostasis. However, there were trends toward possible benefits of low recombinant factor VIIa doses, whereas high recombinant factor VIIa doses adversely affected hemostasis.

Reanalysis of Prehospital Intravenous Fluid Administration in Patients with Penetrating Truncal Injury and Field Hypotension

In 1994, Bickell et al. published a prospective study recommending restricting prehospital intravenous fluids (IVF) to less than 100 cc in patients with penetrating truncal injuries and field hypotension, reporting a 30 per cent mortality with IVF restriction and a 38 per cent mortality with liberal IVF use. However, since this study, few papers have investigated whether emergency medical systems (EMS) adhere to these IVF guidelines. The purpose of this study was to determine whether a policy of IVF restriction is being followed and whether the volume of prehospital and emergency department (ED) IVF affects outcome in patients with penetrating truncal injury and field hypotension at a Level I trauma center in Los Angeles County. A retrospective analysis of a trauma database from 1998 to 2005 of all patients with penetrating truncal injury and field hypotension (systolic blood pressure less than 90 mm Hg) was performed. Multiple variables, including originating EMS agency, mechanism of injury, transport time, Injury Severity Score, field and ED vital signs, and IVF volume infused, complications, and mortality were compared. One hundred ninety-four patients with a median age of 26 years with penetrating truncal injury and field hypotension were analyzed. The most common mechanisms of injury were gunshot (73%) and stab (22%) wounds. The median field systolic blood pressure was 80 mm Hg. The median transport time was 11 minutes. The median prehospital IVF was 500 cc with only 25 per cent receiving less than 100 cc of IVF. There were no differences in the amount of IVF administered by the degree of field hypotension or by originating EMS agency. Median ED IVF was 1000 cc. The overall mortality rate was 25 per cent. When a comparison was made of those receiving less than 100 cc prehospital IVF in comparison to those receiving greater than 100 cc, there were no differences detected with respect to median age, systolic blood pressure, Injury Severity Score, transport time, or morbidity rate. The mortality rate was 21 per cent in the group that received greater than 100 cc of IVF in comparison to a 37 per cent mortality rate in the group that received less than 100 cc IVF (P = 0.04). On multivariate analysis, after adjusting for Trauma Injury Severity Score, there were no differences in survival by the amount of prehospital or ED IVF administered. It appears that the recommendations of IVF restriction for patients with penetrating truncal injuries and field hypotension are not being followed by Los Angeles County EMS. There were no differences in survival with respect to the amount of prehospital or ED IVF. Given the retrospective nature of this study, further investigation is needed to define the role of prehospital IVF resuscitation in these patients.

Assessment of Adverse Events in the Demise of Pediatric Burn Patients

Given the contention that survival is to be expected from even the most severely burned child, then, intuitively, at least some pediatric burn victims die because of suboptimal care. The purpose of this study is to assess the impact of any adverse events that may have contributed to the death of burned children. Four surgeons with specialty training in pediatric burn care reviewed the clinical course and autopsy findings of 71 burned children who died after admission to a burn center during a 10-year interval. Reviewers were asked to determine the predominant factor or factors contributing to each child's demise and to assess the significance of any deviations from optimal care. For the 10 years under review, overall mortality for all pediatric burns was 2.4%. Of these deaths, 25% had burns encompassing less than 50% body surface area. The reviewers identified lung damage as the most frequent cause of death, which was deemed largely unpreventable. Conversely, hypovolemia related to inadequate prehospital fluid resuscitation and failure to obtain and maintain a patent airway were considered the second and third most common factors in a child's death and deemed preventable under ideal circumstances. This review implies that deficiencies in health care contribute to the demise of many burned children. The most notable areas for improvement are in fluid resuscitation and airway control. This suggests that quality assurance and educational initiatives to improve these aspects of care may have the greatest impact on further improving survival of burned children.
