Autonomic Nervous System
This system is known as the "fight or flight" system
What is the sympathetic nervous system?
Drugs that cause relaxation of blood vessels and decrease blood pressure
What are vasodilators?
This drug is considered the first-line vasopressor in septic shock
What is Norepinephrine (Levophed)?
This benzodiazepine is commonly used for ICU sedation and amnesia
What is Midazolam (Versed)?
This electrolyte primarily affects cardiac electrical activity
What is Potassium (K+)?
This drug is commonly used to treat ventricular tachycardia and ventricular fibrillation
What is Amiodarone?
This system is for "rest and repair"
This system is for "rest and repair" What is the parasympathetic nervous system?
These medications block the conversion of angiotensin I to II
What are ACE inhibitors?
This medication has a dose-dependent dopaminergic, beta, and alpha effects
What is Dopamine?
This sedative is a lipid-based anesthetic commonly used for ventilated ICU patients
What is Propofol (Diprivan)?
Tall peaked T waves are associated with this condition
What is hyperkalemia?
This antiarrhythmic works by blocking sodium channels
What is Lidocaine?
These receptors increase HR, contractility, and conduction.
These receptors increase HR, contractility, and conduction. What are Beta-1 receptors?
This class blocks calcium entry into smooth muscle and reduces HR and BP
What are calcium channel blockers?
This vasopressor is a pure alpha agonist causing peripheral vasoconstriction
What is Phenylephrine (Neosynephrine)?
This sedative is an alpha-2 agonist that causes sedation without respiratory depression
What is Dexmedetomidine (Precedex)?
This electrolyte is used to treat torsades de pointes
What is magnesium?
This medication treats life-threatening ventricular arrythmias
What is Procainamide?
These receptors cause bronchodilation.
These receptors cause bronchodilation. What are Beta-2 receptors?
This drug is a short-acting calcium channel blocker used for rapid BP control
What is Clevidipine (Cleviprex)?
This hormone-based vasopressor works on V1 and v2 receptors
What is Vasopressin (ADH)?
This opioid analgesic is 100x more potent than morphine
What is Fentanyl?
This electrolyte acts as an antidote for calcium channel blocker toxicity
What is calcium?
This drug prolongs the myocardial action potential and refractory period
What is amiodarone?
These drugs stimulate receptors to produce a response
What are agonists?
This calcium channel blocker is commonly used for rate control in atrial fibrillation
What is Diltiazem (Cardizem)?
This vasopressor stimulates alpha and beta receptors and is used in cardiac arrest and anaphylaxis
What is Epinephrine (Adrenaline)?
This dissociative anesthetic increases BP and HR due to sympathetic stimulation
Antiarrhythmic drugs can effect heart rate, conduction, and contractility these effects
What is chronotropic, dromotropic, and inotropic effects?
