Purpose: This study was aimed to describe Helicopter Emergency Medical Services (HEMS) and analyze the flight nurses' activities in HEMS. Methods: Data were collected retrospectively from the air transportation reports that contained data of 168 patients transported by aircraft to G University medical center in Incheon since June, 2012 to March, 2013. Data were analyzed using descriptive statistics, and Mann-Whitney U test. Results: Average distance of flights was 44.0 km, duration of field treatment took 13.6 minutes, and duration of a flight from scene to hospital was 14.5 minutes. Nursing activities were categorized into 12 direct nursing activities and 5 nursing management activities, and a total number of 7806 nursing activities were occurred in HEMS. The most frequently performed nursing activity was measurement and monitoring (27.9%) followed by medication (11.5%) and respiratory management (8.7%). The most frequent nursing management were information management (11.0%). Nursing activities performed were significantly different depending on the patient's level of consciousness, cause of illness, crew configuration, and type of transportation. Conclusion: This study described HEMS nursing activities performed by flight nurses. Difference in nursing activities according to patient characteristics, crew configuration and type of transportation requires flight nurses to be prepared through educational programs to improve nursing activities and nursing management during air transportation.

Purpose: Helicopter transport with medical teams has been proven to be effective, with improvements in patient survival rates. This study compared and analyzed the clinical characteristics and treatment outcomes of trauma patients transported by doctor helicopters according to whether patients were transferred after a clinical evaluation or without a clinical evaluation. Methods: This study retrospectively reviewed data from the Korean Trauma Data Bank of trauma patients who arrived at a regional trauma center through doctor helicopters from January 1, 2014, to December 31, 2022. The patients were divided into two groups: doctor helicopter transport before evaluation (DHTBE) and doctor helicopter transport after evaluation (DHTAE). These groups were compared. Results: The study population included 351 cases. At the time of arrival at the trauma center, the systolic blood pressure was significantly lower in the DHTAE group than in the DHTBE group (P=0.018). The Injury Severity Score was significantly higher in the DHTAE group (P<0.001), and the accident to trauma center arrival time was significantly shorter in the DHTBE group (P<0.001). Mortality did not show a statistically significant between-group difference (P=0.094). Surgical cases in the DHTAE group had a longer time from the accident scene to trauma center arrival (P=0.002). The time from the accident to the operation room or from the accident to angioembolization showed no statistically significant differences. Conclusions: DHTAE was associated with significantly longer transport times to the trauma center, as well as nonstatistically significant trends for delays in receiving surgery and procedures, as well as higher mortality. If severe trauma is suspected, air transport to a trauma center should be requested immediately after a simple screening test (e.g., mechanism of injury, Glasgow Coma Scale, or Focused Assessment with Sonography in Trauma), which may help reduce the time to definitive treatment.

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.

2015년 바레인에서 귀국한 한국인이 처음으로 메르스 확진 판정을 받으면서 대한민국 메르스 유입이 확인되었다. 최초 메르스 확진 판정 후 감염자가 병원으로 후송 된 후 2차 감염자가 늘어났고 그 이후 대한민국은 메르스 공포에 떨어야 했다. 이 때 격리구급차 도입이 이루어지고 있었으나 들것 이송 중 오염에 대해서는 뾰족한 방법이 없었고 격리구급차 도입이 제한적으로만 이루어지고 있었기에 서울대학교 병원과 서울시립대학교에서는 이송용 격리 이송 장치 및 공기정화장치(양·음압기)를 개발하였다. 하지만 메르스 사태가 발생한지 4년이 지난 현재까지도 격리이송장치 및 공기정화장치에 대한 성능평가 시험법이 미흡한바 본 연구에서는 시뮬레이션 및 시험을 통하여 도출된 차압, 공기의 흐름에 따른 결과를 통하여 소형격리장비 내부와 외부의 차압을 측정하여 바이러스의 외부유출 및 내부밀폐가 가능한 최소 수치를 제안 하였으며, 이를 통하여 소형격리이송장비의 성능평가 및 시험법에 대하여 제안하였다. 해당 소형격리이송장비의 중요 기능을 정의하고 이를 평가항목으로 선정하여 현실과 유사한 상황을 모사하여 성능평가를 수행하였다. 그 결과 격리이송장치 내부의 양압과 음압의 적절한 압력 구성과 헤파필터의 명확한 기준이 명시되어 격리이송장치 및 공기정화장치의 성능기준을 명확하게 규정해야 함을 도출하였다.

운송은 우리 사회에서 사람들과 화물, 정보의 이동을 제공함으로서 중요한 역할을 해왔다. 하지만 교통사고와 교통 체증, 대기 오염 등을 유발하는 부정적인 면도 가지고 있다. 이러한 문제의 주원인은 차량 수의 급격한 증가에 있다. 이러한 문제들을 완화시키는 가장 쉬운 방법은 새로운 도로 기반 시설을 건설하는 것이지만, 시간과 비용, 공간 등과 같은 자원의 제약이 있다. 따라서 기존 도로 기반 시설을 효율적이고 안전하게 관리할 필요가 있다. 본 논문에서는 유비쿼터스 센서 네트워크를 사용한 도로에서 긴급 차량 출동을 위한 빠르고 안전한 도로 예약 방식을 제안한다. 또한 앰블런스나 소방차, 경찰차와 같은 긴급차량들이 목적지에 빠르고 안전하게 도착할 수 있도록 세가지 예약 방법에 대한 비교분석을 하고 다양한 도로 상태에서 예약되지 않은 경우에 비해 예약을 한 경우 약 1.09 ~ 1.2 배 빠른 속도를 낼 수 있음을 시뮬레이션을 통해 보여준다. 도로 예약을 사용하는 경우 긴급차량의 속도를 줄이지 않으면서 안전하게 운행할 수 있으며, 교통 체증을 완화시키는 데도 도움을 줄 수 있음을 보인다.
