Therapeutic hypothermia after cardiac arrest in Lower Austria - a cross-sectional survey

This study was undertaken to evaluate the use of therapeutic hypothermia (TH) after cardiac arrest in Lower Austria. A questionnaire was sent to intensive care units (ICUs) in Lower Austria. Methods of inducing and maintaining hypothermia, the practise of rewarming, concomitant therapies and reasons not to cool were documented. Of the 23 ICUs 10 (43%) used TH. Nine (39%) cooled their patients to 32-34 degrees C and one to 34-35 degrees C. Duration of cooling was 24 h (n=8, 35%), 24-48 h (n= 1) or 48h (n= 1). For induction of hypothermia, ICUs used cold infusions (n=5, 22%), surface (n=7, 30%) or endovascular cooling (n=6, 26%). The same methods were used during the maintenance period. Reasons not to cool were insufficient staff resources (n=4, 17%), technical complexity of cooling (n=4, 17%) and too little information (n=3, 13%). In conclusion, TH has been poorly implemented in Lower Austria. The reasons for not using hypothermia could possibly be dispelled by education.
