What drug class is Amiodarone
|
Antiarrhythmic
|
|
|
What are the pharmacological actions are Amiodarone
|
Amiodarone is a antyarrhythmic that prolongs the action potential and refractory period. It inhibits adrenergic stimulation. Slows the sinus rate, increases PR and QT intervals, and decreases peripheral vascular resistance.
|
|
|
What are the indications of Amiodarone.
|
VF/Pulseless Vtach
Wide complex tachycardia with a pulse |
|
|
What are the contraindications for Amiodarone
|
Hypersensitivity
Cardiogenic shock Bradycardia AV blocks Liver disease |
|
|
What are the precautions and side effects of Amiodarone
|
Hypotension
braducardia cardiogenic shock headache/diziness AV block |
|
|
What is the dose for Amiodarone.
|
-VF/Pulseless, V tach 300 MG IV/IO repeat at 150 mg after 3-5 minutes.
-Wide complex tachycardia: 150 MG IV/IO over 10 minutes - Post resuscitation maintanance: 1mg/min over 6 hours - Max Dose: 2.2g IV/IO over 24 hours |

|
Electrolyte
|
|
|
What are the pharmacology and actions magnesium sulfate
|
magnesium sulfate acts as a physiological calcium channel blocker, CNS depressant and anti convulsant. It depresses the function of smooth, skeletal and cardiac muscles
|
|

|
|
What are the classes of Pralidoxime (2PAM)
|
Cholinesterase reactivator
|
|
|
What are the pharmacological actions for Pralidoxime (2PAM)
|
Reactivates the cholinesterase inhibited by phosphate esters by displacing the enzyme from its receptor sites. This restores the normal functions of neuromuscular transmission
|
|
|
What are the indication Pralidoxime (2PAM)
|
Organophosphate poisoning
|
|
|
Contraindications of Pralidoxime (2PAM)
|
Severe cardiac disease
peptic ulcer asthma myocardial infarction hypersensitivity to procainamide/procaine |
|
|
what are the precautions and side effects of Pralidoxime (2PAM)
|
Tachycardia
hypertension dizziness |

|
1-2G in 250-500 ML NS unfused over 15-30 minutes; if no iv access is available then 1-2g IM/SC
|
|
|
What is the drug class for Sodium Bicarbonate
|
Alkalinizing Agent
|
|
|
Pharmacological actions of Sodium Bicarbonate
|
Raises the pH of blood plasma by buffering excess hydrogen ionds. Provides vascular bicarbonate to assist in the buffer system in reducing the effects of metabolic acidosis and in the treatments of some overdoses.
|
|
|
What are the indications for Sodium Bicarbonate
|
