Our primary focus immediately following return of spontaneous circulation (ROSC) is aimed at ensuring adequate perfusion of the patient’s vital organs and decreasing cerebral damage. After we have assessed and addressed O2 saturation, ETCO2, and BP, we may consider the use of an antiarrhythmic infusion if the patient has ventricular ectopy on the ECG. Indications for use of an antiarrhythmic after ROSC. Determining which antiarrhythmic to use post cardiac arrest. Administration of Amiodarone or Lidocaine to control ventricular ectopy after ROSC. The use of Amiodarone post arrest if no antiarrhythmics were administered prior to obtaining ROSC.

I hope you'll consider contributing. Every donation makes a difference in the fight against breast cancer! http://main.acsevents.org/goto/paultaylor (Paul Taylor's ACS Fundraiser) THANK YOU!
