Albuterol, CaCl, Na Bicarb Flashcards
random deck
Albuterol dose
2 puffs
Albuterol peak
30 - 60 minutes
Albuterol duration
2 - 4 hours
Albuterol MOA
selective beta-2 receptor agonist
Albuterol side effects
- tremor
- increased HR
- decrease in arterial oxygenation with acute, severe asthma
- hypokalemia
Calcium chloride ACLS dose, calcium replacement dose, and post-CABG dose
ACLS dose: 2 - 4 mg/kg
calcium replacement dose: 3 - 6 mg/kg (over 5 - 15 minutes)
post-CABG dose: 5 - 10 mg/kg
Calcium chloride duration
10 - 20 minutes
Calcium chloride is recognized as what type of drug?
a positive inotrope
Sodium Bicarbonate dosing in cardiac arrest, in less urgent forms of metabolic acidosis, and in infants?
cardiac arrest - rapid infusion of one to two 50mL (8.4%) vials every 5 - 10 minutes as needed (not recommended in the ACLS guidelines)
less urgent - 2 - 5 mEq/kg over a four to eight hour period, and may be added to IV fluids
in infants - the 4.2% solution is recommended, at a dose that does not exceed 8 mEq/kg/day.
Sodium bicarbonate is contraindicated in which patients?
hypochloremic patients
(either from patients vomiting, continuous GI suctioning, or patients receiving diuretics known to produce a hypochloremic alkalosis)
Sodium bicarbonate should be used cautiously in which patients?
patients at risk for fluid retention, d/t the sodium in sodium bicarb
(patients with congestive heart failure, severe renal insufficiency, clinical states in which there exists edema with sodium retention)
Why has sodium bicarbonate been removed from the ACLS algorithm?
can cause intracellular acidosis
(elevates plasma pH by combining with hydrogen ions to form carbonic acid, which readily dissociates into carbon dioxide and water. Because carbon dioxide, but not bicarbonate, readily crosses cell membranes and the blood-brain barrier, the resulting arterial hypercapnia will cause intracellular tissue acidosis)
