This month we've got three papers covering a wide variety of topics and practice in emergency care.

First up we'll be looking at whether pre-charging the defibrillator prior to rhythm analysis in cardiac arrest can decrease our hands-off time.

Next we take a look at a paper that can help inform our assessment and investigation of trauma patients; looking at the risk of concomitant injuries with regards to specific levels of spinal trauma.

Finally have a think about how different methods of extrication affect spinal movements from road traffic collisions; will it make a difference to your extrication method and speed?

Once again we'd love to hear any thoughts or feedback either on the website or via twitter @TheResusRoom.
