Class of digoxin
|
Cardiac Glycoside
|
|
Action of digoxin
|
Rapid acting, used in the treatment of CHF and rapid atrial dysrhythmias. It increases the force and velocity of myocardial contraction and cardiac output. It also decreases conduction through AV node which decreases HR
|
|
Indications for digoxin
|
Increase cardiac output in CHF, stabilize supraventricular tachydysrhythmias
|
|
Dose of digitalis
|
0.25 to 0.5mg slow IV
|
|
Contra for digitalis
|
hyper, V-Fib, or V-tach except due to CHF
|
|
Precautions for digoxin
|
Reduce if digoxin taken within 2 weeks, potentiated by an MI and with hyopkalemia, hyopcalcaemia, advanced heart disease, incomplete HB, cor pulmonale, hyperthyroidism, resp. impairment, children/elderly/debilitated patients, hypomagnesaemia
|
|
Side effects of digitalis
|
H/A, hallucinations, dysrhythmias, hyoptension, AV block, NV
|
|
Class for lidocaine
|
Antiarrythmic
|
|
Action for lidocaine
|
Antidysrhythmic that suppresses automaticity and raises stimulation threshold of ventricles. Causes sedation, anticonvulsant and analgesia.
|
|
Indications for Lido
|
Pulseless V-Tach, V-fib
Ventricular tachycardia with pulse |
|
Doses for lidocaine
|
Pulseless V-tach, V-Fib: 1-1.5 mg/kg IV rep 3-5 min to 3mg/kg, 2-4mg/min drip after resuscitation.
Vent. tachy with pulse: 1-1.5 mg/kg slow IV repeat @ half dose 5-10 min to 3 mg/kg |
|
Contra for lido
|
Hyper, supracentricular dysrhythmias, stokes-adams syndrome, 2nd or 3rd degree HB, bradycardias
|
|
Precautions for lidocaine
|
hepatic/renal impairment, CHF, hypoxia, resp. depression, hypovolemia, myasthenia gravis, shock, debilitated patients, elderly, family history of malignagt hypothermia
|
|
Side effects of Lidocaine
|
Dizziness, wild excitment, psychosis
High doses: resp. drepression, convulsion, bradycardia, HB, CV collapse, NV |
|
Action of activated charcoal
|
A specially prepared charcoal that will absorb and bind toxins from the GI tract
|
|
Indication for AC
|
Acute ingested poisining
|
|
Dose for AC
|
1g/kg PO with 6-9oz. water
|
|
Contra for AC
|
uncontrolled airway, ingestion of cyanide, mineral acids, caustic alkalis, organic solvents, iron, ethanol, methanol
|
|
Precautions for AC
|
only after emesis or in cases where emesis is contraindicated
|
|
Side Effects
|
vomiting in rapid admnin. abd cramping/bloating
|
|
Action for benadryl
|
blocks histamine release, reducing bronchoconstriction, vasodilation, and edema
|
|
Indications for benadryl

|
25-50mg IV IM PO
|
|
Contra for benadryl
|
asthma and lower resp. disease
|
|
Precautions/Sideeffects: for benadryl
|
may induce hyoptension, HA, palpitations, tachycardia, sedation, drowsiness, and or disturbed coordination
|
|
Class for lasix
|
Loop diuretic
|
|
Action for lasix
|
Rapid acting diuretic and hypersensitive that inhibits sodium reabsorbption by kidney. vasodilating reduces venous return and cardiac workload
|
|
Indications for furosemide
|
CHF and pulmonary edema
|
|
Dose for Furosemide
|
40-120 mg slow IV
|
|
Precautions for lasix
|
infants, elderly, hepatic impairment, nephritic syndrome, cardiogenic shock assoc with AMI, gout, or patients recieving digitalis or potassium depleting steroids
|
|
side effects for furosemide
