RESUMEN
This study investigated in-hospital outcomes and related factors in patients diagnosed with postearthquake crush syndrome after the earthquakes in Kahramanmaras, Türkiye. One thousand twenty-four adult patients diagnosed with crush syndrome were analyzed. Data on demographic characteristics, clinical presentation, laboratory values, treatments, and outcomes were collected. A total of 9.8% of patients died during their hospital stay. Nonsurvivors were generally older, more likely to have preexisting chronic kidney disease, and faced more severe injuries and complications, including hypotension-shock, arrhythmias, elevated markers of renal dysfunction, and higher rates of acute kidney injury (AKI) and compartment syndrome. In addition, intensive care unit needs were higher. Multivariate analysis confirmed that age, injury severity, shock, high potassium, uric acid, and lactate levels on admission, development of AKI, compartment syndrome, and intensive care unit admission were significant predictors of mortality. Better disaster preparedness and improved health care infrastructure could be potential explanations for improved in-hospital mortality in the current era, as compared to previous earthquakes.

INTRODUCTION: On February 6, 2023, two separate destructive earthquakes with magnitudes of 7.7 and 7.5 occurred in Kahramanmaras, Türkiye. More than 50,000 people lost their lives, and over 100,000 were reported injured. In this study, patients referred to hospitals with burn diagnosis and management of burn wounds following the disaster were evaluated. MATERIAL AND METHODS: Information on burn injury admissions related to the earthquake was collected from all burn facilities in the country within 15 days after the earthquake. The patients' demographics, being under rubble, rescue times, burn causes, grafting procedures, and deaths were recorded. RESULTS: Following the earthquake, burn victims were transferred to the 13 Burn Treatment Centers located in 10 provinces. A total of 191 patients were burned. Among the burn patients, 101 (52.9%) were rescued from the rubble 2-60 h after the earthquake. Eight patients who were hospitalized at the burn centers died. Scalding and flame burns were the most common etiologies. Burned total body surface area, concomitant crush injury, hospitalization, and mortality was higher among the patients trapped under rubble (p < 0.001, p < 0.001, p < 0.001, and p < 0.001, respectively). Victims who stayed longer time under the rubble required significantly more grafting procedures (p < 0.001). CONCLUSION: In a literature review, it was observed that there are a limited number of publications reporting earthquake-related burns. In the February, 6 Türkiye earthquake, flame burns were seen due to small fires that occurred in collapsed buildings during the earthquake. And also contact burns and hot liquid burns were seen in earthquake victims trapped under rubble. Bursting hot water pipes, overturned stoves, contact with hot central heating radiators, and heated construction irons caused scalding and contact burns. It is believed that prolonged entrapment may cause delays in burn treatment or lead to deeper burns due to prolonged contact with the burning agent, increasing hospitalization rates. This earthquake once again drew attention to burn injuries that could occur during and after earthquakes, including those that may occur under rubble.

The aim of the study is to determine the usefulness of base excess (BE) and creatine kinase (CK) in predicting the extent of damage to the extremities, the need for hemodialysis, and the likelihood of mortality in crush injuries. Our study included patients who were affected by the earthquakes that occurred in Kahramanmaras/Turkey on February 6, 2023 and were diagnosed with crush injuries. The study was a retrospective observational study. We used chi-square test, independent sample t test, analysis of variance (ANOVA) to examine whether CK and BE values can be used to predict damage to the extremities, hemodialysis requirement, and mortality. A total of 299 patients were included in the study. A statistically significant relationship was found between BE and extremity damage, hemodialysis requirement, and mortality (Pâ <â .005). A statistically significant difference was also seen in terms of extremity damage and hemodialysis requirement with CK (Pâ <â .001), while there was no statistically significant difference seen in mortality (Pâ =â .204). BE may serve as a predictive biomarker for the development of extremities damage, hemodialysis requirement, and mortality. CK is not predictive of mortality.

BACKGROUND: On February 6th, 2023, two consecutive earthquakes struck southeastern Türkiye with magnitudes of 7.7 and 7.6, respectively. This study aimed to analyze the clinical and laboratory findings, as well as management of pediatric victims with Crush Syndrome (CS) and Acute Kidney Injury (AKI). METHODS: The study included pediatric earthquake victims who were presented to Mersin University Hospital. Clinical and laboratory characteristics of the patients were collected retrospectively. RESULTS: Among 649 patients, Crush injury (CI), CS and AKI was observed in 157, 59, and 17 patients, respectively. White blood cell count (12,870 [IQR: 9910-18700] vs. 10,545 [IQR: 8355-14057] /µL, P < 0.001), C-reactive protein (51.27 [IQR: 14.80-88.78] vs. 4.59 [1.04-18.25] mg/L, P < 0.001) and myoglobin levels (443.00 [IQR: 198.5-1759.35] vs. 17 [11.8-30.43] ng/ml) were higher in patients with CS, while their sodium (IQR: 134 [131-137] vs. 136 [134-138] mEq/L, P < 0.001) levels were lower compared to non-CS patients. An increase in myoglobin levels was identified as an independent risk factor for developing CS (OR = 1.017 [1.006-1.027]). Intravenous fluid replacement was administered to the patients with CS at a dose of 4000 cc/m2/day. Hypokalemia was observed in 51.9% of the CS patients on the third day. All patients with AKI showed improvement and no deaths were reported. CONCLUSIONS: Hyponatremia and increase in inflammation markers associated with CS may be observed. An increase in myoglobin levels was identified as a risk factor for CS. Hypokalemia may be seen as a complication of vigorous fluid therapy during hospitalization.

BACKGROUND: Two earthquakes on 6 February 2023 destroyed 10 cities in Türkiye. We report our experience with pediatric victims during these catastrophes, with a focus on crush syndrome related-acute kidney injury (Crush-AKI) and death. METHOD: Web-based software was prepared. Patient demographics, time under rubble (TUR), admission laboratory data, dialysis, and kidney and overall outcomes were recorded. RESULTS: A total of 903 injured children (median age 11.62 years) were evaluated. Mean TUR was 13 h (interquartile range 32.5, max 240 h). Thirty-one of 32 patients with a TUR of >120 h survived. The patient who was rescued after 10 days survived. Two-thirds of the patients were given 50 mEq/L sodium bicarbonate in 0.45% sodium chloride solution on admission day. Fifty-eight percent of patients were given intravenous fluid (IVF) at a volume of 2000-3000 mL/m2 body surface area (BSA), 40% at 3000-4000 mL/m2 BSA and only 2% at >4000 mL/m2 BSA. A total of 425 patients had surgeries, and 48 suffered from major bleeding. Amputations were recorded in 96 patients. Eighty-two and 66 patients required ventilator and inotropic support, respectively. Crush-AKI developed in 314 patients (36% of all patients). In all, 189 patients were dialyzed. Age >15 years, creatine phosphokinase (CK) ≥20 950 U/L, TUR ≥10 h and the first-day IVF volume <3000-4000 mL/m2 BSA were associated with Crush-AKI development. Twenty-two deaths were recorded, 20 of 22 occurring in patients with Crush-AKI and within the first 4 days of admission. All patients admitted after 7 days survived. CONCLUSIONS: These are the most extensive pediatric kidney disaster data obtained after an earthquake. Serum CK level was significantly associated with Crush-AKI at the levels of >20 950 U/L, but not with death. Adolescent age and initial IVF of less than 3000-4000 mL/m2 BSA were also associated with Crush-AKI. Given that mildly injured victims can survive longer periods in the disaster field, we suggest uninterrupted rescue activity for at least 10 days.

INTRODUCTION: It was aimed primarily to analyze the development of acute kidney injury (AKI) and treatment management in critically ill patients who developed rhabdomyolysis due to earthquake-related crush syndrome. METHODS: We evaluated 18 patients with crush syndrome who were admitted to the intensive care unit (ICU) after the great earthquake in February 2023 in Turkey. RESULTS: AKI occurred in 83% (n:15) of these patients after ICU admission (AKI-1; 16.6% [n:3], AKI-2; 16.6% [n:3], and AKI-3; 50% [n:9]). While the majority of patients who developed crush syndrome were treated with high volume intravenous hydration, only 33% (n:6) of all patients required renal replacement therapy. All patients who developed AKI had complete recovery in renal functions at the end of 2 months. CONCLUSION: There is no need for routine renal replacement therapy in the treatment of AKI, which is frequently seen in patients with crush syndrome. Most can be treated with high volumes of intravenous fluid.

Crush syndrome due to traumatic rhabdomyolysis is one of the most significant problems to occur following earthquakes. On February 6, 2023, millions of people in Turkey were affected by two consecutive Kahramanmaras earthquakes. The present study reports the analysis of clinical and laboratory findings of crush syndrome in pediatric earthquake victims admitted to our hospital from our region where the earthquake had a devastating effect. Clinical and laboratory findings concerning earthquake victims with crush syndrome were analyzed within the first week to determine what factors are predictive of kidney replacement therapy (KRT). The data of patients were retrospectively collected from medical records. A total of 310 children were admitted as earthquake victims to the pediatric emergency department. Ninety-seven (31%) of these patients had crush syndrome. Fifty-three (55%) of those with crush syndrome were female. The mean age was 10.9 ± 4.7 years, and the mean time under the rubble was 30.6 ± 23.8 h. Twenty-two patients (23%) required KRT. Hemodialysis was applied to 16 (73%) of them, and hemodiafiltration was applied to the other six (27%) in the pediatric intensive care unit. Regarding creatine kinase (CK) levels, the area under the receiver operating characteristic (ROC) curve (AUC) for predicting KRT was 0.905 (95% confidence interval [CI] 0.848-0.963; p < 0.001). The optimal cut-off value was 40,000 U/L with a sensitivity of 86% and a specificity of 83%. In terms of the percentage of body area crushed, the AUC for predicting KRT was 0.907 (95% CI 0.838-0.976; p < 0.001). The optimal cut-off value was 30% with a sensitivity of 86% and a specificity of 88%. Multiple logistic regression analysis showed that each 10% increase in body area crushed (OR 4.16, 95% CI 1.58-10.93, p = 0.004) and 1 mg/dl increase in the serum phosphorus level (OR 4.19, 95% CI 1.71-10.28, p = 0.002) were significant risk factors for dialysis treatment. CONCLUSIONS: Crush syndrome and kidney problems are common following disasters like earthquakes. Clinical and laboratory findings at admission can predict dialysis requirement in earthquake victims. While CK elevation, body area crushed percentage, and increased phosphorus level were predictive of dialysis treatment, time under the rubble was not. Even if the patients were under the rubble for a short time, acute kidney injury (AKI) may develop as a result of severe hypovolemia due to crush injuries, and patients may need KRT. WHAT IS KNOWN: â¢Crush syndrome after earthquakes needs to be treated carefully in victims and can cause AKI and mortality when not treated timely and appropriately. WHAT IS NEW: â¢CK level elevation, body area crushed percentage, and increased phosphorus level are predictive of dialysis treatment. â¢The time under the rubble may not be predictive of dialysis requirement.

INTRODUCTION: Earthquakes are sudden-onset natural disasters that are associated with substantial material damage, resulting in the collapse of built environment with a high rate of mortality, injury, and disability. Crush syndrome, which can be seen after devastating earthquakes, can lead to acute kidney injury (AKI) and patients may require amputation, fasciotomy, and dialysis. Supportive treatment has an important role in the prognosis of these patients. STUDY OBJECTIVE: The aim of this study was to investigate the demographic and clinical characteristics of traumatic earthquake survivors admitted to the emergency department (ED) of a hospital, which was close to the earthquake zone but not affected by the earthquake, after the February 6, 2023 Kahramanmaras (Turkey) earthquakes. MATERIALS AND METHODS: This study was conducted by retrospectively analyzing the data of 1,110 traumatized earthquake survivors admitted to the ED of a tertiary care university hospital from February 6th through February 20th, 2023. Age; gender; time of presentation; presence of comorbid diseases; ED triage category; duration of stay under debris; presence of additional trauma; laboratory tests; presence of AKI; presence of crush injury and injury sites; supportive treatment (fluid replacement and intravenous [IV] sodium bicarbonate); need for amputation, dialysis, and fasciotomy; duration of hospitalization; and outcome of ED were evaluated. RESULTS: Of the 1,110 traumatic victims in this study, 55.5% were female patients. The mean age of the patients was 45.94 (SD = 16.7) years; the youngest was 18 years old and the oldest was 95 years old. Crush injury was detected in 18.8% and AKI in 3.0% of the patients. Dialysis, amputation, and fasciotomy were required in 1.6%, 2.8%, and 1.4% of the patients, respectively. In total, 29.2% of patients were hospitalized, including 2.9% admitted to the intensive care unit (ICU) and 26.3% to the relevant ward. In total, 0.3% of the patients included in the study died at ED. CONCLUSION: Post-earthquake patients may present with crush injury, AKI may develop, and fasciotomy, amputation, and dialysis may be needed, so hospitals and EDs should be prepared for natural disasters such as earthquakes.

INTRODUCTION: Disasters and accidents have occurred with increasing frequency in recent years. Primary disasters have the potential to result in mass casualty events involving crush syndrome (CS) and other serious injuries. Prehospital providers and emergency clinicians stand on the front lines of these patients' evaluation and treatment. However, the bulk of our current knowledge, derived from historical data, has remained unchanged for over ten years. In addition, no evidence-based treatment has been established to date. OBJECTIVE: This narrative review aims to provide a focused overview of, and update on, CS for both prehospital providers and emergency clinicians. DISCUSSION: CS is a severe systemic manifestation of trauma and ischemia involving soft tissue, principally skeletal muscle, due to prolonged crushing of tissues. Among earthquake survivors, the reported incidence of CS is 2-15%, and mortality is reported to be up to 48%. Patients with CS can develop cardiac failure, kidney dysfunction, shock, systemic inflammation, and sepsis. In addition, late presentations include life-threatening systemic effects such as hypovolemic shock, hyperkalemia, metabolic acidosis, and disseminated intravascular coagulation. Immediately beginning treatment is the single most important factor in reducing the mortality of disaster-situation CS. In order to reduce complications from CS, early, aggressive resuscitation is recommended in prehospital settings, ideally even before extrication. However, in large-scale natural disasters, it is difficult to diagnose CS, and to reach and start treatments such as continuous administration of massive amounts of fluid, diuresis, and hemodialysis, on time. This may lead to delayed diagnosis of, and high on-site mortality from, CS. To overcome these challenges, new diagnostic and therapeutic modalities in the CS animal model have recently been advanced. CONCLUSIONS: Patient outcomes can be optimized by ensuring that prehospital providers and emergency clinicians maintain a comprehensive understanding of CS. The field is poised to undergo significant advances in coming years, given recent developments in what is considered possible both technologically and surgically; this only serves to further emphasize the importance of the field, and the need for ongoing research.

BACKGROUND: In such cases where sudden destruction and injury are very high, search and rescue teams and hospitals can be the most important determining factors between people's lives and deaths. METHODS: This study was conducted retrospectively, after the two catastrophic earthquakes (Türkiye-Syria Earthquakes) by taking the records of the patients who admitted to our hospital. Patients' admission times, diagnoses, demographic data, triage codes, medical interventions, hemodialysis needs, crush syndrome and mortality rates were analyzed. RESULTS: In the first 5 days after the earthquake, 247 earthquake-related patients were admitted to our hospital. The most intense period of admission to the emergency department was the first 24 h. The most intensive period of surgical procedures was 24-48 h. It was observed that Orthopedic surgical procedures were applied most frequently and the most common cause of mortality was crush syndrome. CONCLUSION: In terms of preparations for earthquakes, especially in hospitals in the earthquake zone it will be beneficial for each hospital to make hospital disaster plans. For this reason, we thought it would be useful to share our experiences during this disaster.

INTRODUCTION: Primary disasters may result in mass casualty events with serious injuries, including crush injury and crush syndrome. OBJECTIVE: This narrative review provides a focused overview of crush injury and crush syndrome for emergency clinicians. DISCUSSION: Millions of people worldwide annually face natural or human-made disasters, which may lead to mass casualty events and severe medical issues including crush injury and syndrome. Crush injury is due to direct physical trauma and compression of the human body, most commonly involving the lower extremities. It may result in asphyxia, severe orthopedic injury, compartment syndrome, hypotension, and organ injury (including acute kidney injury). Crush syndrome is the systemic manifestation of severe, traumatic muscle injury. Emergency clinicians are at the forefront of the evaluation and treatment of these patients. Care at the incident scene is essential and focuses on treating life-threatening injuries, extrication, triage, fluid resuscitation, and transport. Care at the healthcare facility includes initial stabilization and trauma evaluation as well as treatment of any complication (e.g., compartment syndrome, hyperkalemia, rhabdomyolysis, acute kidney injury). CONCLUSIONS: Crush injury and crush syndrome are common in natural and human-made disasters. Emergency clinicians must understand the pathophysiology, evaluation, and management of these conditions to optimize patient care.

BACKGROUND: During a major earthquake, escape attempts or collapsed buildings can result in injury, disability, and even death for victims. The aim of this study is to examine the demographic characteristics, clinical outcomes, and injuries of victims admitted to the emergency department within the first week after an earthquake. METHODS: This is a retrospective observational study conducted on earthquake victims who were admitted to the emergency services of a tertiary medical faculty and a training and research hospital in the city of Diyarbakir, located in the Southeastern Anatolia Region of Turkey, from February 6 through February 12, 2023. RESULTS: Of the eligible 662 earthquake victims, the mean age was 10.66 (SD = 4.78 [min 0, max 17]) in children, 36.87 (SD = 4.78 [min 18, max 63]) in adults, and 72.85 (SD = 5.83 [min 65, max 84]) in the elderly. Women constituted 52.8% of the victims, 19.7% were children, and 8.0% were elderly. Sixty-one percent (61.0%) of earthquake victims were admitted to emergency services in the first three days following the disaster; 37.7% of all victims were transferred from other affected cities to Diyarbakir. In all, 80.2% of the victims were admitted as survivors to the emergency services (36.8% were rescued under rubble, 40.1% with injuries while attempting to escape the earthquake, and 3.3% with nontraumatic reasons) and 19.8% were deceased under rubble. The majority of the 131 deceased victims were women (52.7%), 20.6% were children, and 7.6% were elderly. An estimated 38.3% of victims were hospitalized (20.9% in the ward and 17.4% in the intensive care unit [ICU]). For all age groups that survived under the rubble, the extremities were most injured (53.6% for children, 53.1% for adults, and 55.5% for the elderly). Of adult survivors, 26.6% needed only fluid therapy, renal replacement treatment (hemodialysis) was required 20.7%, and 11.8% required amputation. Of children survivors under the rubble, renal replacement treatment (hemodialysis) was required for only four, seven required amputation, and 12 needed only fluid resuscitation for crush injury. Of elderly survivors, two needed only fluid therapy, renal replacement treatment (hemodialysis) was required for two, and no amputation was required. Six patients survived under the rubble and died in the ICU. CONCLUSION: The definition of the demographic characteristics and clinical outcomes of earthquake patients is critical to the development of preparedness, response, and recovery policies for future disasters.

Earthquakes are unpredictable natural disasters accompanied by material damage and many victims. In the case of a person remaining trapped under the collapsed material, the development of crush syndrome can occur. Crush syndrome is the result of traumatic rhabdomyolysis and is present in 2%-15% of all injured persons in an earthquake. It is not easy to recognize, and proper treatment is challenging. Persons who have a clear crush injury and/or have been immobilized for more than four hours should be considered potential victims of crush syndrome. Therefore, knowledge about crush syndrome must be comprehensive and accessible to all parties involved. In this paper, the management of crush syndrome victims, which includes the principles of triage, and medical and logistic principles as well, is presented. Triage principles are presented at the level of triage priorities, places, and diagnoses. Medical principles, crucial for crush syndrome, are presented regarding the duration of compression and time before or after extraction of the patient. Logistic principles provide an overview of the priorities and modes of transport in relation to distance of health institutions, and the importance of management and education associated with crush syndrome. Each country with recognized disasters (natural or man-made) in which crush-related victims are expected, will benefit if the knowledge about triage, medical and logistic principles for crush syndrome is incorporated in their educational programs and regularly updated.

Orthopedic injuries, especially fractures of long bones as well as multiple fractures and comminuted fractures, are very common after destructive disasters (e.g., earthquakes, wars, and hurricanes). Another frequent problem is traumatic rhabdomyolysis, which may result in crush syndrome, the second most frequent cause of death after direct traumatic impact following earthquakes. To improve outcomes, interventions should be initiated even before extrication of the victims, which include maintenance of airway patency and spine stabilization, stopping traumatic bleeding by any means, and initiating fluid resuscitation. On-site amputations have been extensively debated to liberate the victims if the release of trapped limbs is impossible. Early after the rescue, a primary survey and triage are performed, a fluid resuscitation policy is planned, complications are treated, the wounds are decontaminated, and the victim is transported to specialized hospitals. A triage and primary survey are also performed at admission to the hospitals, which are followed by a secondary survey, physical, laboratory, and imaging examinations. Washing and cleaning of the soft-tissue injuries and debridement in open, necrotic wounds are vital. Applications of fasciotomies and amputations are controversial since they are associated with both benefits and serious complications; therefore, clear indications should be defined. Crush syndrome has been described as the presence of systemic manifestations following traumatic rhabdomyolysis, the most important component of which is acute kidney injury that may contribute to fatal hyperkalemia. The overall mortality rate is around 20% in crushed patients, which underlines the importance of prevention. Treatment includes maintaining of fluid electrolyte and acid-base balance, application of dialysis, and also prevention and treatment of complications. The principles and practices in disaster medicine may differ from those applied in routine practice; therefore, organizing repeated training courses may be helpful to provide the most effective healthcare and to save as many lives as possible after mass disasters.

Crush injuries present a challenging case for medical providers and require knowledge and skill to manage the subsequent damage to multiple organ systems. In an austere environment, in which resources are limited and evacuation time is extensive, a medic must be prepared to identify trends and predict outcomes based on the mechanism of injury and patient presentation. These injuries occur in a variety of environments from motor vehicle accidents (at home or abroad) to natural disasters and building collapses. Crush injury can lead to compartment syndrome, traumatic rhabdomyolysis, arrythmias, and metabolic acidosis, especially for patients with extended treatment and extrication times. While crush syndrome occurs due to the systemic effects of the injury, the onset can be as early as 1 hour postinjury. With a comprehensive understanding of the pathophysiology, diagnosis, management, and tactical considerations, a prehospital provider can optimize patient outcomes and be prepared with the tools they have on hand for the progression of crush injury into crush syndrome.

OBJECTIVES: To date, we have only limited evidence of the determinants of earthquake inpatient mortality-related factors. This study is among the first to explore related factors of inpatient deaths using data from multiple hospitals and multiple earthquakes. METHODS: We included and retrospectively analyzed data on 32,976 earthquake inpatients in the West China Earthquake Patients Database. Of these, we analyzed the records of 284 patients who died during hospitalization. We collected 12 dichotomous variables with reference to previous reports: patients' age (both ≤ 15 years and ≥ 65 years), gender, prehospital treatment, intensive care unit (ICU) admission, the presence of severe traumatic brain injury (TBI), trunk injury, severe poly-trauma, crush syndrome, multiple-system organ failure (MSOF), infection, and cardiac/respiratory disease. We performed multivariate logistic regression analysis to explore independent related factors of mortality. RESULTS: Ultimately, we identified severe TBI, MSOF, old age (≥ 65 years), ICU admission, crush syndrome, and cardiac/respiratory disease as independent mortality-related factors. Severe TBI was the greatest risk factor of inpatient death (ods ratio [OR], 31.913, 95% confidence interval [CI], 20.484-49.720), followed by MSOF (OR 30.905, 95% CI, 21.733-43.947). CONCLUSION: To reduce earthquake inpatient mortalities, the related factors analyzed in this study should be prioritized in future inpatient earthquake response strategies.

PURPOSE: To investigate the effect of ischemic postconditioning (IPostC) on skeletal muscle and its optimal protocol. METHODS: This article is about an animal study of rat model of crush syndrome. Sixty rats were randomized into nine different IPostC intervention groups and a control group. The anesthetized rats were subjected to unilateral hindlimb 3-kg compression with a compression device for 6 h, followed by nine different IPostC intervention protocols. RESULTS: Serum levels of creatine kinase (CK) at 3 h post-crush became 2.3-3.9 times among all 10 groups after crush. At 72 h post-crush, serum CK level was reduced to 0.28-0.53 time in all intervention groups. The creatinine (CREA) level in the control group was elevated to 3.11 times at 3 h post-crush and reduced to1.77 time at 72 h post-crush. The potassium (K+) level in the control group was elevated to 1.65 and 1.41 time at 3 and 72 h post-crush, respectively. CONCLUSIONS: Our IPostC intervention protocols can effectively protect rats from crush-induced elevation of serum CK, CREA, and K+ levels. The timing of IPostC intervention should be as early as possible, to ensure the protective effect.

Acute kidney injury (AKI) is frequent during wars and other man-made disasters, and contributes significantly to the overall death toll. War-related AKI may develop as a result of polytrauma, traumatic bleeding and hypovolemia, chemical and airborne toxin exposure, and crush syndrome. Thus, prerenal, intrinsic renal, or postrenal AKI may develop at the battlefield, in field hospitals, or tertiary care centers, resulting not only from traumatic, but also nontraumatic, etiologies. The prognosis usually is unfavorable because of systemic and polytrauma-related complications and suboptimal therapeutic interventions. Measures for decreasing the risk of AKI include making preparations for foreseeable disasters, and early management of polytrauma-related complications, hypovolemia, and other pathogenetic mechanisms. Transporting casualties initially to field hospitals, and afterward to higher-level health care facilities at the earliest convenience, is critical. Other man-made disasters also may cause AKI; however, the number of patients is mostly lower and treatment possibilities are broader than in war. If there is no alternative other than prolonged field care, the medical community must be prepared to offer health care and even perform dialysis in austere conditions, which in that case, is the only option to decrease the death toll resulting from AKI.
