Welcome back to May's papers of the month! First up this month we'll be looking at an RCT focussed on prehospital intra-arrest management and comparing an early move in arrest towards ECMO-CPR and invasive treatment, versus remaining on scene continuing ALS until achieving a ROSC. Does E-CPR hold the promise we are hoping for? Next up we take a look at another RCT on pad placement for electrical Cardioversion-BMI of AF, are antero-posterior pads superior to the standard antero-lateral position? Finally we look at the potential for remote supervision of pre-hospital ultrasound, has technology moved the bar in what can be achieved? Once again we’d love to hear any thoughts or feedback either on the website or via twitter @TheResusRoom. Simon & Rob
