Difference between amiodarone and adenosine and atropine.
Atropine is an anticholinergic….it’s going to dry things up and will increase HR….usually give with pre-op meds to dry secretions up and also during symptomatic bradycardia.
Amiodarone is a Class III antiarrhythmic which prolongs phase 3 of the cardiac action potential. It also has some beta-blocker and CCB like effects on the AV and SA node. Commonly used in afib, vfib, and vtach.
Adenosine causes a transient AV Block. Useful for pharmacological conversion of SVT.
Tx for three types of Obstructive Shock
Cardiac tamponade - IV fluids, inotropes, pericardiocentesis
Massive PE - IV fluids, inotropes, thrombolytics
Tension pneumo - needle decompression, chest tube to follow
Anaphylaxis treatment
3-5mL 1:1000 epinephrine IM (1.5 mL children)
Benadryl (H1) and Pantoprazole (H2)
Ventolin 5mg
Steroids IV
FLUIDS 1-2L IV NS Bolus
