PURPOSE
We evaluated the efficacy of ultrasound-guided lower extremity nerve block in trauma patients.
METHODS
From July 2013 to April 2014, 17 patients with multiple trauma had lower extremity nerve block for immediate management of open wound in the lower extremity. We evaluated the patient satisfaction of the anesthesia and any complications related to the block.
RESULTS
During the lower extremity nerve block, incomplete nerve block occurred in one patient. This is the second case, the reason for this was the lack of technique. There was no anesthetic complications.
CONCLUSION
Ultrasound-guided lower extremity nerve block in trauma patients is an effective anesthesia technique in the immediate management of open wound in lower extremities.

PURPOSE
The purpose of this study was to analyze the characteristics and severity of wrist injuries in snowboarding.
METHODS
December 2005 to February 2008, Snowboarders who experienced wrist injures were included in this study. On the basis of the medical records and radiographic evaluation, the severity of distal radius fracture was classified according to the Arbeitsgemeinschaft fur Osteosynthesefragen/Association for the Study of Internal Fixation (AO/ASIF) classification.
RESULTS
Most of the injured snowboarders were a either of the beginner (35 cases, 46.1%) or the intermediate (27 cases, 35.5%) level. The most common cause of injury in snowboarding was a slip down (60 cases, 78.9%). Comminuted and articular fractures classified as AO types A3, B, and C, which required surgical reduction, made up 42.3% of the distal radial fractures in snowboarders. When we analyzed the differences in severity between the educated and the non-educated groups, an A2 type injury in the AO classification was the most common type of injury in the educated group (20 cases, 38.5%), it means less severe fractures ocurred in the educated group (p=0.045). The most frequent injury mechanism of fractures was slip down (48 cases, 63.2%), and a slip down backwards was the dominant type of slip down (36 cases, 75.0%) (p=0.031).
CONCLUSION
Among the snowboarders in this study who suffered self-down injury to the wrist, more fractures were associated with a backwards slip down than with a forward slip down due to over extension. For educated snowboarders the severity of fracture was lower than it was for uneducated snowboarders.

PURPOSE
Trauma is the 5th most common leading cause of death in Korea, but there has been no appropriate management system for patients until now. We analyzed the main causes of death in trauma patients by comparing the characteristics of those patients with the characteristics of patients who survived. We feel this analysis should have a positive effect on the development of an appropriate trauma management system in Korea.
METHODS
We retrospectively reviewed trauma patients who had been admitted to the Department of General Surgery from February 2002 to February 2007. We compared several expected risk factors between the mortality and the survival group. Data on the transportation, arrival time at the emergency center, amount of transfusion, initial shock index, cause of death, and initial physical condition according to RTS (Revised trauma score), ISS (Injury severity score) and TRISS (Trauma and Injury Severity Score) were collected. Patients with ISS lower than 12 were excluded.
RESULTS
Three hundred sixty-six(366) patients with multiple injuries were included. There were 40 patients in the mortality group and 326 patients in the survival group. The mean arrival time (minutes) to emergency center was longer in the mortality group (137.6 vs 93.6 p 0.04). The total amount of transfusion (ml) was larger in the mortality group (7139 vs 2470 p 0.01). The initial shock index was higher in the mortality group (1.45 vs 1.17 p<0.01). The RTS, ISS, and TRISS were not statistically different between the groups. In the multivariate analysis, mean arrival time and initial shock index were important factors for survival.
CONCLUSION
If the mortality rate of trauma patients is to be reduced , the arrival time at the emergency center should be minimized. Improvement of the emergency medical transfer service system is very important for achieving that.
