Comparing Doppler Ultrasonography and Computerized Tomography Angiography in Emergency Department Evaluation of Earthquake-Related Crush Injuries: A Case Series Analysis.

OBJECTIVE: This case series aims to provide a comprehensive description of the utilization of doppler ultrasonography (USG) and computerized tomography angiography (CTA) in evaluating patients with earthquake-induced crush injuries in the emergency department (ED). METHODS: This retrospective case series was conducted on 11 patients who presented with crush injuries following a seismic event. These patients underwent initial assessment using doppler USG, with CTA performed when deemed necessary. Clinical outcomes and diagnostic findings were systematically reviewed. RESULTS: A cohort of 11 earthquake-related crush injury patients (six females, five males; age 3-59 years), predominantly with lower extremity injuries, with entrapped durations that ranged from 12 to 128 hours. Transport centers received patients from both affected regions and nearby provinces. Initial X-rays identified fractures in two cases. Doppler USG and subsequent CTA were employed for vascular evaluation, with CTA confirming doppler USG findings. Of the 11 patients, five exhibited abnormal doppler USG findings. Four patients required dialysis and four underwent amputation surgery. Fasciotomy and debridement procedures were performed in five and seven patients, respectively. Three patients received hyperbaric oxygen therapy (HBOT). CONCLUSION: Doppler USG emerged as a dependable tool for assessing vascular injuries in earthquake-related crush injuries, offering an effective alternative to CTA without the associated contrast agent risks. These findings underscore the need for further research to establish definitive imaging guidelines in these challenging clinical scenarios.

Earthquake-related isolated blunt thoracic trauma patients: A special population study in the emergency department.

OBJECTIVE: The objective of this study is to compare patients with severe and mild blunt thoracic trauma, who survived an earthquake and presented to the emergency department (ED), in order to identify factors influencing the severity of trauma in earthquake-related thoracic injuries. METHODS: This retrospective, cross-sectional, observational comparative study included patients with isolated thoracic injuries due to the February 6th Kahramanmaras earthquake. The patients were categorized into severe and mild groups based on chest trauma scoring (CTS), and their characteristics were compared. RESULTS: The study included 53 patients, with 43 (88.1%) classified as having mild thoracic trauma and 10 (18.9%) classified as having severe thoracic trauma. There was no significant difference in the duration of entrapment between the groups (p = 0.824). The incidence of hemothorax, pneumothorax, rib fractures, and pneumomediastinum did not differ significantly between the two groups (p > 0.05). However, severe thoracic trauma was associated with a higher rate of lung contusion compared to the mild group (p = 0.045). The severe group exhibited significantly higher median scores for lung contusion, rib fractures, and total CTS compared to the mild group (p < 0.001). The mortality rate was significantly higher in the severe group (40%, n = 4) compared to the mild group (2.3%, n = 1) (p = 0.003). CONCLUSION: The duration of entrapment did not significantly affect the severity of thoracic injuries in earthquake-related blunt thoracic trauma. However, lung contusion was found to be a more prominent feature in these injuries compared to other clinical conditions such as hemothorax and pneumothorax. These findings highlight the distinct clinical implications of earthquake-related thoracic trauma and may have implications for management strategies in these cases.

Enhancing Triage and Management in Earthquake-Related Injuries: The SAFE-QUAKE Scoring System for Predicting Dialysis Requirements.

OBJECTIVES: Identifying early predictors of dialysis requirements in earthquake-related injuries is crucial for optimal resource allocation and timely intervention. This study aimed to develop a predictive scoring system, named SAFE-QUAKE (Seismic Assessment of Kidney Function to Rule Out Dialysis Requirement), to identify patients at high risk of developing acute kidney injury (AKI) and requiring dialysis. METHODS: A retrospective analysis was conducted on a cohort of 205 patients presenting with earthquake-related injuries. Patients were divided into two groups based on their need for dialysis: the no dialysis group (n = 170) and the dialysis group (n = 35). Demographic, clinical, and laboratory data were collected and compared between the two groups to identify significant predictors of dialysis requirements. The parameters that would form the score were determined by conducting an importance analysis using artificial neural networks (ANNs) to identify parameters that exhibited statistically significant differences in univariate analysis. RESULTS: The dialysis group had a significantly longer median duration of being trapped under debris (48 hours) compared to the no dialysis group (eight hours). Blood gas and laboratory analyses revealed significant differences in pH levels, lactate values, creatinine levels, lactate dehydrogenase (LDH) levels, and aspartate transaminase (AST)-to-alanine transaminase (ALT) ratio between the two groups. Based on these findings, the SAFE-QUAKE rule-out scoring system was developed, incorporating entrapment duration (<45 hours), pH levels (>7.31), creatinine levels (<2mg/dL), LDH levels (<1600mg/dL), and the AST-to-ALT ratio (<2.4) as key predictors of dialysis requirements. This score included 139 patients, and among them, only one patient required dialysis, resulting in a negative predictive value of 99.29%. CONCLUSIONS: The SAFE-QUAKE scoring system demonstrated a high negative predictive value of 99.29% in ruling out the need for dialysis among earthquake-related injury cases. This scoring system offers a practical approach for health care providers to identify patients at high risk of developing AKI and requiring dialysis in earthquake-affected regions.
