Adenosine

Description

A

adenosine can “chemically cardiovert” PSVT to a normal sinus rhythm. It has a half life of 10 seconds and does not cause hypotension

Q

Amiodarone

Description

A

Amiodarone is an antidysrhythmic that prolongs the duration of the action potential and refractory period and relaxes smooth muscles, reducing peripheral vascular resistance and increasing coronary artery flow

16
Q

Bretylium

Description

A

Bretylium causes a release of norepinepherine, depresses ventricular fibrilation, and reduces ectopy. Bretylium surpresses ventricular tachydysrhythmias including vfib with reentry mechanisms

17
Q

Bretylium

Indications

A

ventricular fibrilation and ventricular tachycardia refractory to lidocaine

18
Q

Bretylium

Contraindications

A

none

19
Q

Bretylium

Dosage/Route

A

5mg/kg IV, then 10mg/kg/15-30 mins, to a max of 30mg/kg

20
Q

Lidocaine

Name

A

Xylocaine

21
Q

Lidocaine

Class

A

antidysrhythmic (NA+ blocker)

22
Q

Lidocaine

Description

A

Lidocaine is an antidysrhythmic that supresses automaticity and raises stimulation threshold of the ventricles. it also causes sedation, anticonvulsant and analgesic effects

23
Q

Lidocaine

Indications

A

Pulseless ventricular tachycardia, ventricular fibrillation, ventricular tachycardia with pulses

24
Q

Lidocaine

Contraindications

A

Hypersensitivity to amide-type local anesthetics, supraventricular dysrhythmias, stokes-adam snydrome, 2nd or 3rd degree heart blocks, and bradycardias

25
Q

Lidocaine

Precautions

A

hepatic or renal impairment, CHF, hypoxia, respiratory depression, hypovolemia, myasthenia gravis, shock, elderly

26
Q

Lidocaine

Dosage/Route

cardiac arrest

A

1-1.5mg/kg IV repeated every 3-5 mins up to 3mg/kg, consider half dose for elderly. follow conversion with a drip of 2-4mg/min 1gram/250cc

pedi: 1mg/kg IV, repeat every 3-5 mins, follow conversion with a drip of 20-50 mcg/kg/min

27
Q

Lidocaine

Dosage/Route

head injury premedicate

A

1mg/kg IVP

28
Q

Procainamide

Name

A

Pronestyl

29
Q

Procainamide

Class

A

anti arrhythmic (NA+ blocker)

30
Q

Procainamide

Description

A

Procainamide prolongs ventricular repolarization, slows conduction, and decreases myocardial excitability

31
Q

Procainamide

Indications

A

Ventricular fibrillation, and pulseless ventricular tachycardia refractory to lidocaine

32
Q

Procainamide

Contraindications

A

Hypersensitivity to procainamide or procaine, myasthenia gravis, and 2nd or 3rd degree heart block

33
Q

Procainamide

Precautions

A

hypotension, cardiac enlargement, CHF, AMI, ventricular dysrhythmias from digitalis, hepatic or renal impairment, or bronchial asthma

34
Q

Procainamide

Dosage/Route

A

20-30 mg/min IV drip

Stop Points: 1) up to 17mg/kg to effect, then 1-4 mg/min 2) ectopy resolves 3) QRS widens more than 50% from original 4) hypotension ensues

Pedi: 15mg/kg IV/IO over 30-60 mins
