“…Whether early, advanced medical intervention is beneficial or whether the rapid transport is more beneficial warrants further research. Rapid transport by air for coronary intervention is warranted to meet optimum angiography time windows for patients with acute coronary syndromes requiring immediate coronary intervention [5,11]. As the incidence of re-arrest is low, helicopter transport should be considered in cases of remote geography.…”

BackgroundOut-of-hospital cardiac arrest (OHCA) is a common medical emergency with significant mortality and significant neurological morbidity. Helicopter emergency medical services (HEMS) may be tasked to OHCA. We sought to assess the impact of tasking a HEMS service to OHCA and characterise the nature of these calls.MethodRetrospective case review of all HEMS calls to Surrey and Sussex Air Ambulance, United Kingdom, over a 1-year period (1/9/2010-1/9/2011). All missions to cases of suspected OHCA, of presumed medical origin, were reviewed systematically.ResultsHEMS was activated 89 times to suspected OHCA. This represented 11% of the total HEMS missions. In 23 cases HEMS was stood-down en-route and in 2 cases the patient had not suffered an OHCA on arrival of HEMS. 25 patients achieved return-of-spontaneous circulation (ROSC), 13 (52%) prior to HEMS arrival. The HEMS team were never first on-scene. The median time from first collapse to HEMS arrival was 31 minutes (IQR 22–40). The median time from HEMS activation to arrival on scene was 17 minutes (IQR 11.5-21). 19 patients underwent pre-hospital anaesthesia, 5 patients had electrical or chemical cardioversion and 19 patients had therapeutic hypothermia initiated by HEMS. Only 1 post-OHCA patient was transported to hospital by air. The survival to discharge rate was 6.3%.ConclusionOHCA represents a significant proportion of HEMS call outs. HEMS most commonly attend post-ROSC OHCA patients and interventions, including pre-hospital anaesthesia and therapeutic hypothermia should be targeted to this phase. HEMS are rarely first on-scene and should only be tasked as a first response to OHCA in remote locations. HEMS may be most appropriately utilised in OHCA by only attending the scene if a patient achieves ROSC.

“…2,11,12 Helicopter transport is particularly useful for managing cardiovascular and neurologic patients who require early intervention or surgery that is critical for their survival. 9,[15][16][17] In addition, it is often essential for the safe delivery of babies by island residents. 10 Ulleung Island is serviced by 3 regular sea routes, each of which accommodates a single round-trip passenger ship at a fixed time once per day.…”

“…Despite extensive studies of HEMS outcomes in Western countries, information regarding the outcomes of patients transported by helicopter from single islands that are geographically isolated and medically vulnerable is currently lacking. [9][10][11][12] In this study, we examine the outcomes of patients transported by helicopter from the Ulleung-gun Health Center and County Hospital to mainland South Korea.…”
