PURPOSE
The purpose of this study was to analyze the effectiveness of regional trauma center's management.
METHODS
Data collected between January 2013 and December 2015 from a regional trauma center registry was retrospectively reviewed. The patients who had injury severity score (ISS) greater than 15 and over the age of 18 were included. We compared annual general characteristics, the injury mechanism, the pathway of transportation, the injury severity score, the length of stay in emergency department (ED) and hospital, the in-hospital mortality.
RESULTS
The annual numbers of enrolled patients were 337, 334 and 278, respectively. No significant differences were found in the annual patient's median ages, injury mechanism, ISS and in-hospital mortality. The annual proportions of coming from other hospital and the median length of stay in hospital were increased after establishment of regional trauma center. The annual median lengths of stay in ED were decreased remarkably.
CONCLUSION
Through the establishment of regional trauma center, the length of stay in ED can be reduced but not in-hospital mortality. More multidisciplinary cooperation and well-organized study is needed to reduce mortality of major trauma patients and maximize effect of regional trauma center.

PURPOSE
Traumatic brain injury (TBI) is the most common cause of pediatric trauma patients came to the emergency department. Without guidelines, many of these children underwent repeat brain computed tomography (CT). The purpose of this study was to evaluate the value of repeat brain CT in children with TBI.
METHODS
We conducted a retrospective study of TBI in children younger than 19 years of age who visited the emergency department (ED) from January 2011 to December 2012. According to the Glasgow Coma Scale (GCS) and Pediatric Glasgow Coma Scale score of the patients, study population divided in three groups. Clinical data collected included age, mechanism of injury, type of TBI, and outcome.
RESULTS
A Total 83 children with TBI received repeat brain CT. There were no need for neurosurgical intervention in mild TBI (GCS score 13-15) group who underwent routine repeat CT. 4 patients of mild TBI group, received repeat brain CT due to neurological deterioration, and one patient underwent neurosurgical intervention. Routine repeat CT identified 12 patients with radiographic progression. One patient underwent neurosurgical intervention based on the second brain CT finding, who belonged to the moderate TBI (GCS score 9-12) group.
CONCLUSION
Our study showed that children with mild TBI can be observed without repeat brain CT when there is no evidence of neurologic deterioration. Further study is needed for establish indication for repetition of CT scan in order to avoid unnecessary radiation exposure of children.

PURPOSE
To improve outcome of severe trauma patient, the shortening of transport time is needed. Although helicopter emergency medical services (HEMS) is still a subject of debate, it must also be considered for trauma system. The aim of this study is to assess whether transport method (HEMS versus ground EMS) is associated with outcome among inter-hospital transport.
METHODS
All trauma patients transported to regional emergency center by either HEMS or ground EMS from September 2011 to September 2014. We have classified patients according to two groups by transport method. Age younger than 15 years and self-discharged patients were excluded.
RESULTS
A total of 427 patients were available for analysis during this period. 60 patients were transported by HEMS and 367 patients were transported by ground EMS. HEMS group had higher mortality than ground EMS group (23.3% vs 3.5%; p<0.001), and included more patients with excess mortality ratio adjusted injury severity score (EMR-ISS)above 25 (91.7% vs 48.8%; p<0.001). In the multivariable regression analysis, HEMS was not associated with improved outcome compared with ground EMS, but only EMR-ISS was associated with a mortality of patients (odds ratio, 1.06; 95% confidence interval, 1.04-1.09).
CONCLUSION
In this study, helicopter emergency medical services transport was not associated with a decreased of mortality among the trauma patients who inter-hospital transported to the regional emergency center.

Abstract PDF: PURPOSE
In children, mild traumatic brain injuries (TBI) account for 70~90% of head injuries. Without guidelines, many of these children may be exposed to excess radiation due to unnecessary imaging. The purpose of this study was to evaluate the impact of a mild TBI guideline in imaging of pediatric patients.
METHODS
The medical records of all children who had head computed tomography and were admitted to our hospital with a TBI with Pediatric Glasgow Coma Scale and Glasgow Coma Scale of 14 to 15 were retrospectively reviewed and compared with PECARN Rule.
RESULTS
A total of 1260 children were included and all children checked with head computed tomography. 61 pediatrics had CT positive and presented skull fracture 40, hemorrhage 8, hemorrhagic contusion 7, and diffuse axonal injury 1. Also, 4 patients diagnosed both skull fracture and brain haemorrhage and 1 patient diagnosed both haemorrhage and haemorrhagic contusion.
CONCLUSION
There are many pediatric traumatic patients who exposed to radiation due to CT. But, the most of results were negative. So, consider to follow the CT guideline for children and many do not require brain CT.; Summary

Abstract PDF: PURPOSE
Trauma is one of the most common causes of death for children, and identifying severely injured children quickly in an overcrowded emergency room (ER) is difficult. Therefore, severe injury must be prevented, and the severity of injuries in children must be determined easily from their general characteristics and pre-hospital factors.
METHODS
Injured children younger than 15 years of age who visited the ER from June 2011 to May 2013 were enrolled. According to the revised trauma score (RTS) of the patients, the study population was divided in two groups, a severe group (RTS<7) and a mild group (RTS> or =7). The general characteristics and the pre-hospital factors were compared between the two groups.
RESULTS
Six hundred seventy-three children were enrolled, their mean age was 8.03 (+/-4.45) years, and 476 (70.73%) patients were male. Of these patients, 22 patients (3.27%) were in the severe group, and 651 patients (96.73%) were in the mild group. Fewer males were in the severe group than in the mild group (50.00% vs. 71.43%, p=0.030), and children in the severe group were younger than children in the mild group (3.50 vs. 8.00 years, p=0.049). In the severe group, toddlers (54.55%, p=0.036) were the most common age group. Severe injuries occurred more often in spring (32.81%) and summer (54.56%) than in autumn (9.09%) and winter (4.55%) (p=0.026). The most common places of injury in the severe group were roads (50.00%, p=0.009), and the most common mechanisms of injury in the severe group were traffic accidents (50.00%), followed by falls (31.82%) (p=0.011). Most severely injured children were transferred by ambulance (72.73%, p=0.000).
CONCLUSION
The results of this study may be helpful for identifying severely injured children quickly in the field and the ER. To prevent severe pediatric injuries, precautions and policies based on these results should be established.; Summary

Abstract PDF: PURPOSE
Patients with traumatic brain injury (TBI) were referred from other hospitals for further management. In addition, patients routinely underwent computed tomography examinations of the head (HCT) in the referral hospitals. The purpose of this study was to evaluate retrospectively the utility of routine HCT scans according to the severity of TBI.
METHODS
Patients with TBI referred to our hospital between December 2005 and July 2008 were included in this study. We investigated HCT findings, indications for repeat HCT examinations (routine versus a neurological change), and neurosurgical interventions. The head injury severity was divided into three categories according to the Glasgow Coma Scale (GCS) score, including mild, moderate, and severe TBI. The use of neurosurgical interventions between patients who underwent routine HCT scans and patients who underwent HCT scans for a neurological change were compared according to the severity of TBI.
RESULTS
A total of 81 patients met the entry criteria for this study. Among these patients, 67%(n=54) of the patients underwent HCT scans on a routine basis, whereas 33%(n=27) of the patients underwent HCT scans for a neurological change. A total of 21 patients showed signs of a worsening condition on the HCT scans. Neurosurgical intervention was required for 23(28.4%) patients. For patients who underwent routine HCT examinations, no patient with mild TBI underwent a neurosurgical intervention. However, one patient with moderate TBI and three(13%) patients with severe TBI underwent neurosurgical interventions. The kappa index, the level of agreement for HCT indications of intervention and referral reasons for intervention, was 0.65 for high hierarchy hospitals and 0.06 for low hierarchy hospitals.
CONCLUSION
Routine serial HCT examinations in the referred hospitals would be useful for patients with severe head injury and for patients from low hierarchy hospitals where no emergency physicians or neurosurgeons are available.; Summary

Abstract PDF: Traumatic bilateral abducens nerve palsy is rare and is associated with intracranial, skull and cervical spine injuries. We report a case of bilateral abducens nerve palsy in a 40-month-old patient with a skull base fracture. The injury mechanism was associated with direct nerve injury caused by a right petrous bone fracture and indirect injury by frontal impact on the abducens nerve at the point of fixation to the petrous portion and Dorello`s canal. The emergency physician should be aware of injuries and the mechanism of abducens nerve palsy in head trauma.; Summary
