“… 49 A randomised controlled trial in the out-of-hospital setting found that patients displaying ROOR at 60 s had received lower first shock energies than those not displaying ROOR (1.47 [0.93–2.32] J/kg vs. 4.18 [3.12–5.08] J/kg) although this did not translate to a difference in survival to hospital. 50 No clear evidence of benefit with higher shock energies is therefore provided by the paediatric literature.…”
