The impact of creatine kinase and base excess on the clinical outcome of crush injuries sustained during the Kahramanmaras/Turkey earthquakes on February 6, 2023.

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 (P < .005). A statistically significant difference was also seen in terms of extremity damage and hemodialysis requirement with CK (P < .001), while there was no statistically significant difference seen in mortality (P = .204). BE may serve as a predictive biomarker for the development of extremities damage, hemodialysis requirement, and mortality. CK is not predictive of mortality.

Evaluation of pediatric trauma score and pediatric age-adjusted shock index in pediatric patients admitted to the hospital after an earthquake.

BACKGROUND: In our earthquake-prone country, it is crucial to gather data from regional hospitals following earthquakes. This information is essential for preparing for future disasters and enhancing healthcare services for those affected by earthquakes. This study aimed to evaluate the Pediatric Trauma Score (PTS) and the Shock Index, Pediatric Age-Adjusted (SIPA), in children affected by earthquakes, to provide clinicians with insights into the severity of trauma and hemodynamic stability. METHODS: The study included patients admitted to our hospital's pediatric emergency service within the three weeks following the earthquake. We evaluated their age, sex, admission vital signs, mechanical ventilation requirements, development of crush syndrome, length of hospital stay, PTS, and SIPA. RESULTS: Our study included 176 children (89 females and 87 males) with trauma. Fifty-eight (32.95%) children had crush syndrome, and 87 (49.43%) were hospitalized. The median PTS was 10 (ranging from -3 to 12), and the median SIPA was 1.00 (ranging from 0.57 to 2.10). We observed a negative correlation between the time spent under debris and PTS (r=-0.228, p=0.002) and a positive correlation with the SIPA score (r=0.268, p<0.001). The time spent under debris (p<0.001) and SIPA score (p<0.001) were significantly higher in hospitalized children. PTS was significantly lower in hospitalized children than in others. A PTS cutoff point of 7.5, and a SIPA cutoff point of 1.05, predicted hospitalization in all children. Time spent under debris and SIPA were significantly higher in children with crush syndrome than in others (p<0.001). PTS at a cutoff point of 8.5 and SIPA at a cutoff point of 1.05 predicted crush syndrome in all children. CONCLUSION: PTS and SIPA are important practical scoring systems that can be used to predict the severity of trauma, hospitalization, crush syndrome, and the clinical course in pediatric patients admitted to the hospital due to earthquake trauma.

Mortality Factors in Crush Syndrome.

BACKGROUND: Crush Syndrome is a major cause of morbidity and mortality following large-scale catastrophic earthquakes. Since there are no randomized controlled studies on Crush Syndrome, knowledge on this subject is limited to expert experience. The primary objective is to analyze the epidemiological and demographic characteristics, clinical outcomes, and mortality factors of earthquake victims after the Pazarcik and Elbistan earthquakes on February 6, 2023. METHODS: This cross-sectional and observational retrospective study evaluated 610 earthquake victims who presented to our center between February 6 and April 30, 2023. Among these patients, 128 with Crush Syndrome were included in the study. Patient information was gathered from hospital records during their stay and from national registries upon referral. The primary outcome was to identify risk factors for mortality. Demographic and laboratory data were analyzed by acute kidney injury (AKI) stages; mortality-affecting factors were identified through regression analysis. RESULTS: Of the 128 Crush Syndrome patients (100 adults, 28 children), 64 were female. The AKI rate was 32.8%. Among patients with AKI, the frequency of hemodialysis requirement was 69%, and the mortality rate was 14.2%. The overall mortality rate for patients with Crush Syndrome was 4.6%, compared to 3.9% (19/482) in earthquake victims without Crush Syndrome (p=0.705). Notably, low systolic blood pressure at admission was the only factor significantly affecting mortality in Crush Syndrome patients (Hazard Ratio [HR]: 1.088, p=0.021, 95% Confidence Interval [CI]). CONCLUSION: Our study highlights low systolic blood pressure upon admission as a significant risk factor for increased mortality in Crush Syndrome patients. This finding may contribute to the literature by emphasizing the importance of monitoring blood pressure under rubble and administering more aggressive fluid therapy to patients with low systolic blood pressure.

Clinical features and outcomes of orthopaedic injuries after the kahramanmaras earthquake: a retrospective study from a hospital located in the affected region.

BACKGROUND: The purpose of this retrospective, single-institutional study was to report the clinical features and outcomes of orthopaedic injuries after the Kahramanmaras earthquake. METHODS: An institutional database review was conducted to evaluate the results of patients who applied to our hospital's emergency department after the Kahramanmaras earthquake. Trauma patients referred to orthopaedics and traumatology were identified. Patient records were checked for injury type, fracture site, treatment type (conservative or surgical), surgical technique, and outcome. Diagnosis with crush syndrome and the need for haemodialysis were also noted. Bedside fasciotomy was undertaken based on the urgency of the patient's condition, number of patients and the availability of the operating theatre. A team consisting of a trauma surgeon, a plastic surgeon, a board-certified physician in infectious disease, a reanimation specialist, a general surgeon and a nephrologist followed up with the patients. RESULTS: Within the first 7 days following the earthquake, 265 patients were admitted to the emergency department, and 112 (42.2%) of them were referred to orthopaedics and traumatology. There were 32 (28.5%) patients diagnosed with acute compartment syndrome. Fasciotomy was performed on 43 extremities of 32 patients. Of these extremities, 5 (11.6%) were upper and 38 (88.4%) were lower extremities.The surgeries of 16 (50%) of the patients who underwent fasciotomy were performed in the emergency department. There was no significant difference in terms of complications and outcomes between performing the fasciotomy at the bedside or in the operating theatre (p = 0.456). CONCLUSIONS: Fasciotomy appears to be a crucial surgical procedure for the care of earthquake causalities. Fasciotomy can be safely performed as a bedside procedure based on the urgency of the patient's condition as well as the availability of the operating theatre.

Management of kidney injury in critically ill patients with earthquake-induced crush syndrome: A case series of 18 patients.

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.

BREAKING NEW GROUND: STANDARDIZING RAT MODELS FOR CRUSH SYNDROME INVESTIGATIONS.

ABSTRACT: Crush syndrome (CS), alternatively termed traumatic rhabdomyolysis, is a paramount posttraumatic complication. Given the infeasibility of conducting direct simulation research in humans, the role of animal models is pivotal. Regrettably, the dearth of standardized animal models persists. The objective of this study was to construct a repeatable standardized rat CS models and, based on this, simulate specific clinical scenarios. Methods: Using a self-developed multichannel intelligent small-animal crush injury platform, we applied a force of 5 kg to the hind limbs of 8-week-old rats (280-300 g), subjecting them to a continuous 12 h compression to establish the CS model. Continuous monitoring was conducted for both the lower limbs and the overall body status. After decompression, biochemical samples were collected at 3, 6, 12, and 24 h. In addition, we created a CS model after resection of the left kidney (UNx-CS), which was conceptualized to simulate a more challenging clinical scenario to investigate the physiological and pathological responses rats with renal insufficiency combined with crush injury. The results were compared with those of the normal CS model group. Results : Our experiments confirm the stability of the crush injury platform. We defined the standardized conditions for modeling and successfully established rats CS model in bulk. After 12 h of compression, only 40% of the rats in the CS group survived for 24 h. Systemically, there was clear evidence of insufficient perfusion, reflecting the progression of CS from localized to generalized. The injured limbs displayed swelling, localized perfusion deficits, and severe pathological alterations. Significant changes were observed in blood biochemical markers: aspartate transaminase, lactate dehydrogenase, K+, creatine kinase, creatinine, and blood urea nitrogen levels rose rapidly after decompression and were significantly higher than the sham group. The kidney demonstrated characteristic pathological changes consistent with established CS diagnostic criteria. Although the UNx-CS rat model did not exhibit significant biochemical differences and pathological scores when compared with the standard CS model, it did yield intriguing results with regard to kidney morphology. The UNx-CS group manifested a higher incidence of cortical and medullary protein casts compared with the NC-CS group. Conclusion: We developed and iteratively refined a novel digital platform, addressing the multiple uncontrollable variables that plagued prior models. This study validated the stability of the platform, defined the standardized conditions for modeling and successfully established the CS model with good repeatability in bulk. In addition, our innovative approach to model a clinically challenging scenario, the UNx-CS rat model. This offers an opportunity to delve deeper into understanding the combined effects of preexisting renal compromise and traumatic injury. In summary, the development of a standardized, reproducible CS model in rats represents a significant milestone in the study of Crush syndrome. This study is of paramount significance as it advances the standardization of the CS model, laying a solid foundation for subsequent studies in related domains, especially in CS-AKI.

Imaging findings of traumatic injuries in survivors of the 6 February 2023 earthquake in Turkey.

In the southeastern part of Turkey, two earthquakes measuring 7.7 and 7.8 on the Richter scale occurred within 9 h on 6 February 2023, causing 120,000 injuries and over 50,000 deaths. Evacuees were transferred to various secondary and tertiary hospitals as the health system and hospitals in the affected region were affected by the earthquake. Injuries were mostly caused by blunt trauma and/or prolonged bruising under rubble. The severity and pattern of traumatic injuries in earthquake victims differed from other trauma patients who were not affected by an earthquake. In addition to traumatic injuries that affected multiple body regions and systems, patients who were trapped under debris for long periods of time were also frequently found to have crush syndrome. Pulmonary thromboembolism and hypoxic-ischaemic brain injury were observed in some patients. In this review, we present the imaging findings of traumatic injuries in earthquake victims, emphasising the earthquake-related distinct injury types.

Traumatic Rhabdomyolysis: Crush Syndrome, Compartment Syndrome, and the 'Found Down' Patient.

Traumatic rhabdomyolysis is a systemic manifestation of muscle injury and can occur from various traumatic etiologies, including crush syndrome (CrshS) and compartment syndrome (CS). Although historically described in natural disaster survivors trapped under collapsed structures, the frequency of CrshS has increased in the setting of 'found down' patients from opioid overdoses. Signs and symptoms of the injured limb in CrshS may range from pressure-induced skin changes to neurologic deficits and paralysis. Although its pathophysiology differs from CS, severe injuries may lead to an associated CS. Identifying CS in a patient with CrshS can be difficult but is important to distinguish because it affects treatment. The degree of muscle damage, viability of the remaining muscular compartment, and presence of elevated compartment pressures dictate the need for surgical intervention in the form of fasciotomy. Surgical outcomes from CrshS and delayed CS result in similar high morbidity and surgical complications. This review defines and classifies the types of traumatic rhabdomyolysis and summarizes the outcomes to facilitate timely diagnosis and appropriate management for this population to reduce morbidity associated with these conditions.

Factors affecting the mortality of February earthquakes victims in Türkiye.

OBJECTIVE: >50,000 people died in the February 2023 earthquakes in Türkiye. The aim of this study was to identify the factors affecting mortality rates of the trauma patients who were presented to the emergency department (ED) after the earthquake and provide suggestions for better preparedness strategies for future natural disasters. METHODS: This retrospective, cross-sectional study encompassed data from 955 trauma patients out of 3072 patients aged 18 years and above who sought assistance in the ED. Patients were divided into two groups: the survivor group and the exitus group. Age, gender, the city where patients came from, type of presentation, injured organ systems and mechanisms of injury, laboratory findings, the diagnoses in the ED, time spent in the ED, surgical intervention, and hemodialysis sessions were analyzed. The characteristics of those who could not be identified at the presentation to the ED were subjected to additional analysis. RESULTS: Out of 955 patients, 75.9% had extremity injuries, with crushing injuries (23.6%) being predominant. There were no significant differences in age or gender between the survivor and exitus groups (p = 0.776, p = 0.522), nor in the province of admission (p = 0.249). Clinical factors indicated that the exitus group were more likely to lack identification documents (29.6%), have spent longer trapped under debris, and have a higher frequency of ambulance transportation. Injuries such as chest and abdominal trauma, specific injury types, and amputation or open wounds were notably more frequent in the exitus group. Diagnoses revealed that metabolic causes were more common in exitus group (p < 0.001). While no significant difference existed in the need for emergency surgical intervention (p = 0.939), a higher frequency of emergency hemodialysis was observed among exitus group (p = 0.001). Laboratory findings indicated higher levels of various markers and lower calcium, base excess, and pH levels among those in the exitus group. CONCLUSION: In the aftermath of a devastating earthquake, this study underscores the formidable challenges faced by healthcare systems during natural disasters. To prepare for future disasters, healthcare systems must enhance resilience, develop rapid identification techniques, and adopt a holistic patient care approach.

Factors predicting kidney replacement therapy in pediatric earthquake victims with crush syndrome in the first week following rescue.

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: •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: •CK level elevation, body area crushed percentage, and increased phosphorus level are predictive of dialysis treatment. •The time under the rubble may not be predictive of dialysis requirement.

Demographic and Clinical Characteristics of Earthquake Victims Presented to the Emergency Department with and without Crush Injury upon the 2023 Kahramanmaras (Turkey) Earthquake.

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.

The prevalence of double- and multiple crush syndromes in patients surgically treated for peripheral nerve compression in the upper limb.

OBJECTIVE: The double crush syndrome describes a condition characterized by multifocal entrapment of a nerve. In the upper limb, the high prevalence of carpal tunnel syndrome makes it a common diagnosis of assumption in the setting of median neuropathy. More proximal compressions may tend to be overlooked, under-diagnosed and under-treated in the population. This study aims to map the prevalence of peripheral upper limb nerve compressions among patients undergoing peripheral nerve decompression. METHODS: A prospective case series was conducted on 183 patients undergoing peripheral nerve decompression in a private hand surgery clinic. Level(s) of nerve compression in the median, ulnar and radial nerves were determined by history and physical examination. The prevalence of each nerve compression syndrome or combination of syndromes was analyzed. RESULTS: A total of 320 upper limbs in 183 patients were analyzed. A double crush of the median nerve at the levels of the lacertus fibrosus and carpal tunnel was identified in 78% of upper limbs with median neuropathy, whereas isolated lacertus syndrome and carpal tunnel syndrome were present in only 5% and 17% of affected limbs respectively. Cubital tunnel syndrome affected 12.5% of upper limbs, and 80% of these had concomitant lacertus and carpal tunnel syndromes, compared to only 7.5% with isolated cubital tunnel syndrome. CONCLUSION: A high prevalence should prompt clinicians towards more routine assessment for double crush syndrome to avoid misdiagnosis, inadequate treatment, recurrence, and revision surgeries.

Temporary hypothyroidism in severe crush syndrome: a potential novel entity.

BACKGROUND: Thyroid hormone synthesis is a complex process in the human body. Although the thyroid gland is essential for thyroid hormone synthesis, skeletal muscles also have crucial roles in thyroid hormone metabolism due to the deiodinase activities of the muscle cells. Hypothyroidism-related myopathy is a well-known entity. However, systemic effects of acute myopathies, such as rhabdomyolysis, on thyroid hormone metabolism have not to date been fully clarified. METHODS: Fifty-three earthquake victims were evaluated retrospectively. We investigated the thyroid function tests (TFTs) among patients with creatine kinase (CK) levels higher than 10.000 U/L at admission. Fifteen patients had CK levels higher than 10.000 U/L and 12 of them had data of TFTs, including thyroid stimulating hormone (TSH), free T4 (FT4), and free T3 (FT3) during hospitalization. These patients were evaluated. RESULTS: TSH levels were increased in all seven patients who required HD due to severe crush syndrome. Decreased FT4 levels were detected in 71.4% of them. None of the five non-HD patients had increased TSH levels or reduced FT4 levels. During follow-up, all patients survived. Renal and thyroid functions were normalized during follow-up without thyroxin replacement in patients with no prior history of hypothyroidism. Moreover, TFTs were normalized in two patients with history of hypothyroidism under thyroxine treatment without dose adjustments. CONCLUSIONS: In severe forms of crush syndrome, temporary hypothyroidism might be seen. The exact mechanism underlying this entity is not well-known. Further clinical and experimental trials should be conducted to illuminate the mechanism of disrupted thyroid hormonogenesis in crush syndrome victims.

Thromboprophylaxis in pediatric patients with earthquake-related crush syndrome: a single centre experience.

PURPOSE: Injuries increase the risk of venous thromboembolism (VTE). However, the literature on the management of anticoagulant therapy in pediatric patients with crush injury is limited. In this study, we aimed to share our experience about anticoagulant thromboprophylaxis in pediatric patients with earthquake-related crush syndrome. METHODS: This study included patients who were evaluated for VTE risk after the Turkey-Syria earthquake in 2023. Since there is no specific pediatric guideline for the prevention of VTE in trauma patients, risk assessment for VTE and decision for thromboprophylaxis was made by adapting the guideline for the prevention of perioperative VTE in adolescent patients. RESULTS: Forty-nine patients [25 males and 24 females] with earthquake-related crush syndrome had participated in the study. The median age of the patients was 13.5 (8.8-15.5) years. Seven patients (14.6%) who had no risk factors for thrombosis were considered to be at low risk and did not receive thromboprophylaxis. Thirteen patients (27.1%) with one risk factor for thrombosis were considered to be at moderate risk and 28 patients (58.3%) with two or more risk factors for thrombosis were considered to be at high risk. Moderate-risk patients (n = 8) and high-risk patients aged < 13 years (n = 11) received prophylactic enoxaparin if they could not be mobilized early, while all high-risk patients aged ≥ 13 years (n = 13) received prophylactic enoxaparin. CONCLUSION: With the decision-making algorithm for thyromboprophylaxis we used, we observed a VTE rate of 2.1% in pediatric patients with earthquake-related crush syndrome.

Crush syndrome: a review for prehospital providers and emergency clinicians.

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.

Hospital crisis management after a disaster: from the epicenter of 2023 Türkiye-Syria earthquake.

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.

Evaluation of the 2023 Kahramanmaras earthquake from the perspective of Plastic Surgery Department: A single-center experience.

OBJECTIVES: The aim of this study was to evaluate the treatment management and demographic data of earthquake victims admitted to Plastic Surgery Department of our center after the 2023 Kahramanmaras earthquake. PATIENTS AND METHODS: Between February 6th, 2023 and February 15th, 2023, a total of 120 patients (65 males, 55 females; mean age: 36.3±17.3 years; range, 85 to 88 years) who were consulted to the Plastic Surgery Department of our center were included. Demographic data of the patients, time to admission to the emergency room, removal time under the rubble, type of injury, emergency operation requirement, fasciotomy requirement, hyperbaric oxygen therapy administration, and length of stay in the intensive care unit were evaluated. After the first intervention, patients with compartment syndrome underwent emergency fasciotomy immediately. Perioperative laboratory values of the patients were followed closely to prevent the development of crush syndrome. RESULTS: Due to stay under the rubble, upper extremity soft tissue injury was seen in 46.2% of the patients. The pelvic and abdominal region were the least affected soft tissues in 1.7% patients. Fasciotomy was performed in 75 patients who stayed under the rubble. Hyperbaric oxygen therapy was applied to 21 of 75 patients who underwent fasciotomy. Amputation was performed in four patients, three of which were in the upper extremity and one in the lower extremity, during follow-up after fasciotomy. A total of 10.83% of the patients were treated conservatively and 11.67% of them were reconstructed with free flaps. Totally 7.5% of the patients who stayed under the rubble were hospitalized in our clinic for maxillofacial injuries. A total of 66.6% of these patients were treated surgically, while 33.3% of them were further treated conservatively. CONCLUSION: Proper triage, proper fasciotomy, and appropriate surgical interventions reduce the amputation rate, yielding clinically satisfactory results.

6 February 2023, orthopedic experience in Kahramanmaras earthquake and surgical decision in patients with crush syndrome.

BACKGROUND: The decision of fasciotomy or amputation in crush syndrome is controversial and challenging for surgeons. We aimed to share our experiences after the Kahramanmaras earthquake, to predict the severity of crush syndrome and mortality, and to guide the surgical decision. METHODS: The clinical data of patients during their first week of hospitalization were analyzed retrospectively. Totally, 233 crush syndrome patients were included. Demographic data, physical and laboratory findings, surgical treatments, and outcomes were recorded. RESULTS: The mean time under the rubble was 41.89 ± 29.75 h. Fasciotomy and amputation were performed in 41 (17.6%) and 72 (30.9%) patients. One hundred and two patients (56.7%) underwent hemodialysis. Fifteen patients (6.4%) died. Lower extremity injury, abdominal trauma, and thoracic trauma were associated with mortality. Mortality was significantly increased in patients with thigh injuries (p = 0.028). The mean peak CK concentration was 69.817.69 ± 134.812.04 U/L. Peak CK concentration increased substantially with amputation (p = 0.002), lower limb injury (p < 0.001), abdominal trauma (p = 0.011), and thoracic trauma (p = 0.048). CONCLUSIONS: Thigh injury is associated with the severity of crush syndrome and mortality. Late fasciotomy should not be preferred in crush syndrome. Amputation is life-saving, especially in desperate lower extremity injuries.

Imaging in crush injury: a spectrum of findings in survivors of the twin earthquakes on February 6, 2023.

On February 6, two major earthquakes with magnitudes of 7.8 and 7.7 on the Richter scale hit Turkey and Northern Syria causing more than 50,000 deaths. In the immediate aftermath of the earthquakes, our major tertiary medical referral center received dozens of cases of crush syndrome, presenting with a variety of imaging findings. Crush syndrome is characterized by hypovolemia, hyperkalemia, and myoglobinuria that can lead to rapid death of victims, despite their survival of staying under wreckage for days. The typical triad of crush syndrome consists of the acute tubular necrosis, paralytic ileus, and third-space edema. In this article, we focus primarily on characteristic imaging findings of earthquake-related crush syndrome and divided them into two distinct subsections: myonecrosis, rapid hypovolemia, excessive third-space edema, acute tubular necrosis, and paralytic ileus, which are directly related to crush syndrome, and typical accompanying findings of earthquake-related crush syndrome. Lower extremity compression in earthquake survivors results in the typical third-space edema. In addition to the lower extremities, other skeletal muscle regions are also affected, especially rotator muscles, trapezius, and pectoral muscles. Although it may be relatively easy to better detect myonecrosis with contrast-enhanced CT scans, changing the windowing of the images may be helpful.
