LIDOCAINE
Used in the treatment of VT and VFib as an alternative to amiodarone
MECHANISM OFACTION
■ Class Ib antidysrhythmic
■ Blocks fast sodium channels →stabilization of membranes
DOSE
■ Adult: 1–1.5 mg/kg IV/IO, may be repeated at 0.5–0.75 mg/kg every
5–10 minutes if needed to max of 3 mg/kg
■ Pediatric: 1 mg/kg IV/IO to maximum dose of 100 mg
COMPLICATIONS
■ Hypotension, bradycardia with block, seizures
MAGNESIUM
Used in the treatment of VT or VFib associated with torsades de pointes and
prolonged QT
MECHANISM OFACTION
■ Improves serum magnesium levels →improved QT intervals
DOSE
■ Adult: 1–2 g diluted in 10 mL D 5 W IV/IO
■ Pediatric: 25–50 mg/kg IV/IO (maximum: 2 g)
COMPLICATIONS
■ Hypermagnesemia can cause decreased reflexes and at high levels decreased
respiratory drive, heart block, and asystole.
FIBRINOLYSIS
Administration of tissue plasminogen activator (tPA) may be considered in
patients with PEA due to suspected acute PE or MI. It is not indicated in
undifferentiated PEA.
DOSE
■ Adults: 100 mg IV over 15 minutes
MECHANISM OFACTION
■ Converts plasminogen →plasmin thereby activating fibrinolysis
GLUCOSE
May be a critical intervention in the pediatric population
RESUSCITATION
Excessive administration of
lidocaine may produce
neurological symptoms and
seizures.
Magnesium treats:
Torsades de pointes
Preeclampsia
Severe asthma
