SGEM#107: Can’t Touch This – Hands on Defibrillation

Studi estratti dal podcast di Dr. Ken Milne

• 2014Electrical exposure risk associated with hands-on defibrillationEmergency & ResuscitationIn6 unembalmed cadavers,360 J defibrillationexposed a hands-on rescuer toup to 827 V and 1–8 J, above accepted exposure limits
• 2011Peri-shock pause and survival from out-of-hospital shockable cardiac arrest (ROC Epistry)Emergency & ResuscitationIn 815 out-of-hospital cardiac arrests with a shockable rhythm, a peri-shock pause ≥40 s predicted worse survival to hospital discharge than a pause <20 s.
• 2008Hands-On DefibrillationEmergency & ResuscitationIn 43 patients receiving external biphasic shocks, rescuers keeping a gloved hand on the chest felt no shock and carried only microampere leakage current
• 2012Will medical examination gloves protect rescuers during hands-on defibrillation?Emergency & ResuscitationIn 468 medical examination gloves, double gloving raised breakdown voltage but still leaked at least 0.1 mA more often than a single glove at defibrillation voltages.
• 2010Delayed versus Immediate Defibrillation for Out-of-Hospital Cardiac Arrest due to Ventricular FibrillationEmergency & ResuscitationIn658 patients with out-of-hospital ventricular fibrillation arrest,CPR before defibrillationdid not improvesurvival to hospital dischargecompared withimmediate defibrillation.
