Nitroglycerine actions
Reduce preload and afterload
Vasodilation of cerebral and coronary arteries
Generalized smooth muscle relaxation
Onset of action 1-2min
Glucagon action
Natural polypeptide hormone secreted by the pancreas. Released to breakdown stored glycogen to glucose and inhibits the synthesis of glycogen from glucose. Acts on
receptor sites similar to those of epinephrine producing catecholamine like effects.
Ondasetron action
blocks serotonin receptors in the chemoreceptor trigger zone. It has little effect on vomiting caused by motion sickness.
Narcan dose
0.4-2mg IV/IO/IM (may repeat 2-3min prn)
2-2.5mg ETT
Pedi:
0.1mg/kg IV/IO/IM
Dextrose contraindication
None in documented hypoglycemia
Amiodarone dose
Adult
- VF/Pulseless V tach: 300mg IV/IO repeat at 150mg after 3 – 5 minutes
- Wide complex tachycardia: 150mg IV/IO over 10 minutes
Furosemide action
Lasix is a rapid acting potent diuretic and antihypertensive that inhibits sodium reabsorption by the kidney. Its vasodilating effects reduce venous return and cardiac workload.
Dextrose dose
Adult
25g D50 IV/IO/PO
Thiamine action
Thiamine is vitamin B1. It is required for the metabolism of glucose and the production
of ATP. It is not manufactured by the body and must be constantly provided from
ingested foods.
Succinylcholine action
Succinylcholine as an ultra short acting neuromuscular blocker with a high affinity for Ach receptor sites
Morphine indication
Management of moderate to severe pain
To reduce venous return in pulmonary edema/CHF/AMI
Narcan side effects
Increase BP Increase respirations Tachycardia N/V Tremors Withdrawal symptoms
Atrovent class
Parasympatholytic (anticholinergic) bronchodilator
Epinephrine dose
Adult
-Cardiac arrest
1mg IV 1:10,000
2-2.5mg ETT 1:1000
Activated charcoal contraindication
Uncontrolled airway
Ingestion of cyanide, mineral acids, caustic alkalis, organic solvents, iron, ethanol
or methanol
Sodium bicarb dose
Adult
1mEq/kg IV/IO, may repeat at half dose every 10 minutes
Pediatrics
Same as adult
Nitroglycerine contraindications
Hypotension Chest trauma Head trauma Brain bleed Increased ICP Use of ED drugs Hypersensitivity
Albuterol action
Selective beta-2 adrenergic bronchodilator causing bronchial smooth muscle relaxation with minimal beta-1 or alpha stimulation. Inhibits histamine release reducing mucus secretion and mucosal edema
Activated charcoal action
Activated charcoal is a specially prepared charcoal that when given soon after ingestion of a toxin will adsorb and bind organic toxins from the GI tract
Magnesium sulfate dose
Adult
- Torsades de pointes: 1 – 2g IVP over 1 – 2 minutes
- Eclamptic seizure: 4 – 5g IVP concurrently with up to 5g IM in each buttock then 4 – 5 g every 4 hours
- Bronchodilation: 2g IVP
Succinylcholine class
Depolarizing neuromuscular blocker
Lidocaine dose
Adult
-1 – 1.5mg/kg IV bolus; may repeat doses every 3 – 5 minutes at 0.5 – 0.75mg/kg to a total dose of 3mg/kg. May then start continuous infusion of 1 – 4 mg/min
Use 4mg/ml concentration for infusion
-For endotracheal administration use 2 – 2.5 the loading dose followed by a 10ml NS flush.
Fentanyl class
Narcotic analgesic
Sodium bicarb indication
Prolonged cardiac arrest
Known hyperkalemia
Tricyclic antidepressants/barbiturates OD
Refractory metabolic acidosis
Thiamine dose
Adult
50 – 100mg IV/IO/IM
Pediatrics:
10 – 25mg IV/IO/IM
Atropine class
Parasympatholytic/anticholinergic
Fentanyl action
A potent short acting narcotic agonist used for its analgesic properties. Fentanyl does not cause the vasodilation associated with morphine and so may be acceptable for use in hypovolemic patients.
