Dopamine
Action:
Used to Raise Blood Pressure
Dopamine
Indication:
Hemodynamically significant hypotension in the absence of hypovolemia (not perfusing vital Organs)
Hemodynamically significant hypotension
Systolic < 90 with poor perfusion,oliguria, or changes in mental status
oliguria
low urine output
Dopamine
Cardiac dose
Increases cardiac output, HR and BP
5-10 mcg/kg/min
Dopamine
Indiated for symptomatic bradycardia after max dose of _______
Atropine
Dopamine
Precautions:
-Increases heart rate, may result in myocardial ischemia
-May induce or worsen ventricular dysrhthmias
Dobutamine:
Action
Increases cardiac output
Dobutamine
Indications:
Patients with pulmonary congestion and Left Ventricular dysfunction who can't tolerate vasodilators
Dobutamine
Dosage:
2-20 mcg/kg/min
Dopamine
Action:
Used to Raise Blood Pressure
Dopamine
Indication:
Hemodynamically significant hypotension in the absence of hypovolemia (not perfusing vital Organs)
Hemodynamically significant hypotension
Systolic < 90 with poor perfusion,oliguria, or changes in mental status
oliguria
low urine output
Dopamine
Cardiac dose
Increases cardiac output, HR and BP
5-10 mcg/kg/min
Digitalis (Digoxin, Lanoxin)
Actions:
Increases contractility
Decreases Heart Rate
Digitalis
Controls these dysrhythmias
Controls ventricular response to A-fib & A flutter
Nitroprusside (Nipride)
Indications:
Hypertensive emergencies
Nitroprusside (Nipride)
Actions:
Reduces BP Rapidly
Easily titrated
Well tolerated
Can be rapidly reversed (D/C infusion)
Nitroglycerin (NTG)
Indication:
Angina, Acute MI, CHF
Nitroglycerin (NTG)
Dosage:
1 tablet Sublingual q 5 min x 3
Nitroglycerin (NTG)
Unstable Angina
IV dosage titrated
Definition
Unstable Angina
Chest pain at rest
Nitroglycerin (NTG)
with CHF
IV Dose-treatment of choice for CHF patients with ischemic heart disease
Nitroglycerin (NTG)
with MI
Used with ASA (Aspirin) & thrombolytics in acute MI
Nitroglycerin (NYG)
Precautions:
Headache
hypotension
interaction with other drugs
nausea
syncope
Nitroglycerin (NYG)
Big Precaution
Nitroglycerin (NYG) and sexual enhancement drugs do not mix DEADLY
obtain history
do not administer if within three days of use
Beta Blockers
Inderal
Tenormin
Lopressor
Beta Blockers
ACtions:
Depresses the pumping function of the heart
1)Decrease HR
2)Decrease BP
3)Decrease myocardial contractility
4)Decrease myocardial O2 consumption
Lasix
Action
Loop Diuretic
vasodilation just prior to diuresis (watch for hypotension)
Lasix
Indication:
Pulmonary congestion associated with left ventricular
Lasix
Dosage:
20-40 mg IV
Thrombolytics
Actions:
Dissolve clots
(clot Busters)
USe of thrombolytic should be initiated ASAP after onset of pain
Thrombolytics
Indications:
Pain of AMI (acute Myocardial Infarction)
< 70 years old
6-12 hrs from onset of pain
Thrombolytics
Precautions:
Bleeding
Chest Pain
Reperfusion dysrhythmias
Thrombolytics
Contraindication
Hemorrhagic stroke
Bleeding disorders
ASA
Aspirin-Now one of our most important immdeiate interventions
ASA
Apirin alone started within 24 hours of onset of AMI reduces overall mortality to almost the same degree as thrombolytics
Acute COronary Syndrome
Acute MI
AMI=Necrosis of heart muscle
Acute Coronary Syndrome
Precipitatin Events
Rest, sleep, usual activities, morning hours
Acute MI
Signs and Symptoms
1) Chest pain
2)Radiating pain to shoulders, arms,neck, jaw, or back
3)Prolonged "indigestion"
4)Absense of chest pain(Sometimes)
Acute MI
Diagnosis:
Based on patients history
signs and symptoms
serial ACG's
Blood chemistrys
Blood chemistries of MI
cardiac enzemes, Troponin
Acute MI
Early Treatment
1) O2 decreases extent of ST changes
2) cardiac monitor-VFib most common
3)IV access
4) Pain relief
5)ASA
6)Thrombolytic therapy
