To the Editor Dr Kim and colleagues1 investigated the benefits of prehospital therapeutic hypothermia in patients successfully resuscitated from out-of-hospital cardiac arrest when compared with standard in-hospital cooling. Although this study confirmed2 that prehospital cooling is effective in reducing patients’ temperature and in achieving the target of 34°C earlier, Kim et al1 found no differences either in survival rates or in intact neurological outcomes between the 2 strategies. Some important issues should be further discussed to better interpret the results.
