| | | |
Alpha 2 - CORRECT ANSWER✔✔-Vasodilation and decreased BP.
| | | | | | |
Beta 1 - CORRECT ANSWER✔✔-Effects the heart
| | | | | |
Beta 2 - CORRECT ANSWER✔✔-Effects the lungs
| | | | | |
Norephinephrine (Levophed) - CORRECT ANSWER✔✔-Beta 1 and alpha
| | | | | | | |
stimulant. For hypotension, maintain end-organ perfusion. Increases
| | | | | | |
contractility, increases heart rate , increases SVR, increases BP and
| | | | | | | | | |
coronary blood flow. Side effects: tachycardia, dysthymias,
| | | | | | |
hypertension, peripheral limb ischemia. Dosage: 0.02-0.05 mcg.
| | | | | | |
Considerations: very rapid onset , half life is 2 mins , correct
| | | | | | | | | | | |
hypovolemia before initiating | |
Epinephrine - CORRECT ANSWER✔✔-Beta 1 Beta 2 Alpha stimulant.
| | | | | | | | |
Indication: hypotension, inotropic support, anaphylaxis. Effects:
| | | | | |
increases contractility, increases HR, SVR, relaxes smooth muscle of
| | | | | | | | |
, bronchial tree, produces cardiac stimulation. Side effects: tachycardia,
| | | | | | | |
hypertension, hyperglycemia, myocardial ischemia, dysthymias. Dosage:
| | | | |
0.05-1 mcg. Considerations : monitor blood glucose, 2 min half life,
| | | | | | | | | | | |
never ivp unless dead , IM inject for anaphylactic
| | | | | | | |
Vasopressin - CORRECT ANSWER✔✔-antidiuretic hormone. Indication :
| | | | | | |
hypotension, used as an adjunct when vasopressors and fluid
| | | | | | | | |
resuscitation are ineffective in maintaining goal BP/MAP. Effects: ADH
| | | | | | | | |
causes vasoconstriction, water retention and urine concentration in
| | | | | | | |
order to increase SVR. Side effects: myocardial ischemia, abdominal
| | | | | | | | |
cramps , nausea vomiting, confusion, hyponatremia. Dosage: 0.01-0.04
| | | | | | | |
units. Considerations: fixed dose, 10-20 mins half life
| | | | | | |
Phenylalanine ( neo synephrine ) - CORRECT ANSWER✔✔-Alpha
| | | | | | | |
stimulant. Indication: hypotension. Effects: produces systemic arterial
| | | | | | |
vasoconstriction ( increases SVR ). Side effects : 0.25-5mcg.
| | | | | | | | |
Considerations: Dr must be present or responding to beside for ivp ,
| | | | | | | | | | | |
admin thru central line ,5 min half life
| | | | | | |
Dopamine (Inotropin) Class - CORRECT ANSWER✔✔-Beta one and
| | | | | | | |
Alpha stimulant. Indication: hypotension associated with shock
| | | | | | |
bradycardia or heart block unresponsive to atropine cardiac pacing.
| | | | | | | | |
Effects: effects are related to dosage low-dose 2-10 µg has Beto one
| | | | | | | | | | | |
stimulant increases contractility improves renal perfusion. High dose 10-
| | | | | | | |
20 µg has alpha stimulant increases vasoconstriction and BP. Side
| | | | | | | | | |
effects: tachycardia dysrhythmias angina vasoconstriction palpitations
| | | | | |
