Int J Emerg Med 2011 4 1 Joseph Y Ting Abstract The role for prehospital thrombolysis for ST-elevation acute myocardial infarction and time-critical stroke transfers in the northern Norway aeromedical retrieval system as well as the aero-evacuation impact of increased Arctic expedition tourism could benefit from further discussion by Norum and Elsbak. Close ECG surveillance for ST elevation and retrieval thrombolysis en route to the accepting hospital could be of benefit for acute coronary syndrome patients in northern Norway who require prolonged aeromedical transfer. For patients who remain within a reasonable time frame for stroke thrombolysis up to h after symptom onset expedited transfer for neuroimaging to determine eligibility is recommended. Letter to the Editors Norum and Elsbak describe the clinical and transfer characteristics of fixed and rotary wing aeromedical retrievals carried out in northern Norway for the 10 years 1999-2009 1 . Acute cardiovascular diagnoses were encountered in 76 345 22 of the transported cohort 1 2 although it is not stated which if any of these patients suffered high-risk acute coronary syndromes ACS and or ST elevation acute myocardial infarction STEMI . With one in five of the transported cohort potentially having a STEMI or high-risk ACS a lengthy 3 h 33 min one-way transfer time 1 and attendant delays to accessing primary percutaneous reperfusion Norum and Elsbak s study could have discussed the role of early recognition of ST elevation and prehospital thrombolysis.
