Medication using during cardiac
arrest:
Objectives of drug Treatment:
• To correct hypoxia.
• To correct metabolic acidosis.
• Increase cardiac perfusion during CPR.
• Stimulate cardiac contraction.
• Accelerate heart rate.
• Relieve pain &
• Treat pulmonary edema.
EMERGENCY MEDICATION
General Principles:
• All drugs must be given as bolus dose.
• No chance to give wrong dose.
• No time wasted.
• Always flush with 20 ml NS and raising
the arm.
EMERGENCY MEDICATION
Routes of administration:
• Intravenous: Peripheral or Central line.
• Oral route: Via ET tube: Dose is 2.5 times
the IV dose.
• Intracardiac: Cardiocenthesis technique.
• Intra osseous route: For the children
usually.

Adenosine
• Adenosine is the primary drug used in the
treatment of stable narrow-complex SVT
(Supraventricular Tachycardia).
• Dosing: The first dose of adenosine should be
6 mg administered rapidly over 1-3 seconds
followed by a 20 ml NS bolus. If the patient’s
rhythm does not convert out of SVT within 1 to
2 minutes, a second 12 mg dose may be given
in similar fashion.
• Child: 100mcg/kg 1st dose. 2nd: 200mcg/kg.
