VF or pulseless VT refractory to electrical countershocks and
epinephrine.
Stable VT or stable wide-complex tachycardia of uncertain origin:
repeat doses of half the original dose
If lidocaine successfully converts the VF/VT; begin a continuous
infusion @ 2-4mg/min (1mg=15cc on pump)
* Use 2-2.5 times the IV dose when given via ET tube; followed by
10 ml saline flush
* If toxic symptoms develop (slurred speech, altered LOC, muscle
twitching and seizures), stop the drug or reduce the dose
* Do NOT give this drug if PVCs occur with bradycardia or escape
rhythm.
* No longer recommended for VF/VT prophylaxis in acute MI
* Suppresses ventricular arrhythmias and elevates the
fibrillation threshold (less likely to occur)
