Purpose: The Glasgow Coma Scale (GCS), though it is widely used for triage, has been criticized as being unnecessarily complex. Recently, a 3-point Simplified Motor Score (SMS, defined as obeys commands=2; localizes pain=1; withdrawals to pain or worse=0) was developed from the motor component of the GCS and was found to have a similar test performance for triage after traumatic brain injury when compared with the GCS as the criterion standard. The purpose of this study was to validate the SMS. Methods: We analyzed the patients who visited Kyungpook National University Hospital emergency center after traumatic brain injury from 2006 January to 2006 June. The test performance of the GCS, its motor component, and SMS relative to three clinically relevant traumatic brain injury outcomes (abnormal brain CT scans, Abbreviated Injury Scale (AIS)≥4, and mortality) were evaluated with areas under the receiver operating characteristic curves (AUCs). Results: Of 504 patients included in the analysis, 25.6% had an abnormal brain CT scans, 13.1% had AIS≥4, and 5.0% died. The AUCs for the GCS, its motor component, and SMS with respect to the abnormal CT scans were 0.776, 0.715, and 0.716, and respectively, those for AIS≥4 and mortality, were 0.969, 0.973, and 0.968, and 0.931, 0.909, and 0.909, respectively. Conclusion: The 3-point SMS demonstrated similar test performance when compared with the 15-point GCS score and its motor component for triage after traumatic brain injury in our populations.

Purpose: This study was conducted to evaluate the length of the catheter used in a needle thoracostomy for emergency decompression of a tension pneumothorax by measuring the chest wall thickness (CWT) in patients with chest trauma. Methods: A retrospective review of 201 patients with chest trauma who had been transported the emergency department in a tertiary university hospital in a metropolitan area between 1 January and 31 February 2007 was performed. The average CWT at the second intercostal space (ICS) in the midclavicular line (MCL) was measured by using a chest computed tomography scan. Results: As the left and the right mean CWTs were 3.4±1.0 cm and 3.4±1.0 cm, respectively, there was no significant statistical difference between them. The mean CWT of female patients was significantly higher than that of male patients (p=0.001). The mean CWT of patients under the age of 65 years was significantly thicker than that of the patients over the age of 65 years (p<0.001). Of the studied patients, 12 (6.0%) a CWT >5 cm. Conclusion: A 5 cm-length catheter in a needle thoracostomy may be insufficient for emergency decompression of a tension pneumothorax, so a catheter longer than 5 cm in length is needed.

Purpose: The aim of this study was to evaluate the clinical characteristics of classic heat stroke in Korea and to identify factors of prognosis for heat stroke by comparing a survival group with a non-survival group. Methods: We retrospectively analyzed 27 patients with heat stroke who visited the Emergency Department of Kyungpook National University Hospital from March 2001 to February 2005. First, we divided the patients into two groups, the classic heat stroke group and the exertional heat stroke group, and compared them. Second, we compared the survival group with the non-survival group. Age, sex, cause, place where patients were found, underlying diseases, cooling time, performance of endotracheal intubation, initial Glasgow Coma Scale, initial vital sign, and laboratory findings were reviewed. Results: Five of 27 patients in heat stroke died. The classic heat stroke group had 20 patients. They were old and had more patients in the bathroom than the exertional heat stroke group had. The non-survival group showed lower blood pressure, lower initial GCS score, and higher respiratory rate than the survival group. In laboratory findings, the non-survival group also showed lower HCO3- level, lower albumin level, lower glucose level, more prolonged PT, and higher CK-MB level than the survival group. Delay in recognition of heat stroke and cooling were poor prognostic factors in heat stroke. Conclusion: The classic heat stroke group had patients who were old and found in the bathroom. Early recognition and treatment of heat stroke is important to reduce mortality. Cooling time, initial GCS score, mean arterial pressure, resipratory rate, HCO3-, PT, CK-MB, and albumin seem to be meaningful when forming a prognosis for heat stroke patients.

Purpose: This research was conducted to study whether the specific location of pelvic-bone fractures could increase the risk for injury to the urinary bladder, urethra, or lower gastrointestinal tract. Methods: We retrospectively reviewed the data of 234 patients with pelvic-bone fractures who visited the emergency department of Kyungpook National University Hospital from January 2004 to December 2006. The location of the pelvic-bone fracture was divided into 8 parts. The association of fracture location with injury to the urinary bladder, urethra, or lower gastrointestinal tract was analyzed with Fisher`s-exact test and multiple logistic regression. Results: Nineteen(19) patients had urinary bladder injury, 8 had urethral injury, and 9 had lower gastrointestinal tract injury. The following fracture locations were found to be significant; urinary bladder: sacroiliac (SI) joint (p<0.001), symphysis pubis (p=0.011), and sacrum (p=0.005); urethra: SI joint (p=0.020); lower gastrointestinal tract: symphysis pubis (p=0.028). After the multiple logistic regression analysis, the primary and the independent predictors for each of the injuries were as follows; urinary bladder: sacroiliac joint (p=0.000, odds ratio [OR]=10.469); lower gastrointestinal tract: symphysis pubis (p=0.037, OR=7.009). Conclusion: Consideration of further workup for injuries to the lower gastrointestinal and urinary tract is needed for some locations of pelvic-bone fractures because certain pelvic-bone fracture locations, especially the sacroiliac joint and the symphysis pubis, are associated with increased risk for injury to the lower gastrointestinal and urinary tracts.

Purpose: Early diagnosis and management of therapeutic interventions are very important in chest trauma. Conventional chest X-rays (CXR) and computed tomography (CT) are the diagnostic tools that can be quickly implemented for chest trauma patients in the emergency department. In this study, the usefulness of the CT as a diagnostic measurement was examined by analyzing the ability to detect thoracic injuries in trauma patients who had visited the emergency department and undergone CXR and CT. Methods: This study involved 84 patients who had visited the emergency department due to chest trauma and who had undergone both CXR and CT during their diagnostic process. The patients` characteristics and early vital signs were examined through a retrospective analysis of their medical records, and the CXR and the CT saved in the Picture Archiving Communication System (PACS) were examined by a radiologist and an emergency physician to verify whether or not a lesion was present. Results: Pneumothoraxes, hemothoraxes, pneumomediastina, pulmonary lacerations, rib fractures, vertebral fractures, chest wall contusions, and subcutaneous emphysema were prevalently found in a statistically meaningful way (p<0.05) on the CT. Even though their statistical significance couldn`t be verified, other disorders, including aortic injury, were more prevalently found by CT than by CXR. Conclusion: CT implemented for chest trauma patients visiting the emergency department allowed disorders that couldn`t be found on CXR to be verified, which helped us to could accurately evaluate patients.

Purpose: Clinical observation and research findings show that acute traumatic coagulopathy (ATC) is a major factor that must be addressed in the early care of severe trauma patients. ATC is associated with increased transfusion requirements and poor clinical outcomes. This study aimed to correlate the early predictable factors of ATC with the outcomes in severe trauma patients. Methods: Retrospective data from the trauma registry on severe trauma patients (Injury Severity Score (ISS) ≥16) were used to identify variables independently associated with coagulopathy. Univariate associations were calculated, and a multivariable logistic regression analysis was used to determine variables independently associated with ATC. Results: Patients were mostly male, aged 51.9±17.8 years, with an injury severity score of 24.1±12.4. ATC, as diagnosed in the emergency department (ED), occurred in 17% of the severe trauma patients. Using a multivariable logistic regression analysis, early predictable variables independently associated with ATC were base deficit (odds ratio (OR): 13.03; 95% confidence interval (CI): 3.47-48.93), acute liver injury (OR: 4.24; 95% CI: 1.06-17.00), and transfer from another hospital (OR: 21.00; 95% CI: 3.23-136.60). Conclusion: ATC is associated with mortality in severe trauma patients, and some variables associated with trauma and shock are an independent predictors of ATC. These variables contribute to the early recognition and management of coagulopathy, which may improve the outcome from trauma resuscitation. (J Korean Soc Traumatol 2012;25:72-78)

Purpose: The purpose of this study is to investigate the factors that predict using mechanical ventilation for patients with organophosphate intoxication. Methods: We retrospectively reviewed the medical records of 111 patients with acute organophosphate intoxication and who were treated in our emergency center from January 2000 to December 2008. We compared the toxicologic characteristics, the laboratory findings and the APACHE II scores between the Mechanical Ventilation group (MV group) and the non-Mechanical Ventilation group (the non MV group). Results: Sixty three patients were in the MV group and 48 patients were in the non MV group. In the MV group, the patients had an older age (p<0.001), a larger amount of ingestion (p<0.001), a lower initial serum cholinesterase level (p=0.003), a higher APACHE II score (p<0.001) and they ingested a more toxic agent (p=0.001). There were no significant differences in gender, the type of visit and the arrival time between the MV group and the non MV group. Conclusion: We suggest that the patient’s age, the amount of organophosphate ingestion, the toxicity of the agent, the initial serum cholinesterase level and the APACHE II score are important factors to determine if mechanical ventilation will be applied for patients with organophosphate intoxication.
