Autonomic Nervous System Flashcards
Adrenergic
Refers to the SNS
Cholinergic
refers to the PSNS
Parasympathetic
-Components
Release Acetylcholine from both pre and post ganglionic sites
Sympathetic components
Release Acetylcholine from pre ganglion and
NorEpinepherine from post ganglionic site
Adrenergic Receptors
-Alpha 1 & 2
- Arteriole constriction
- Pupil dilation
- GI smooth muscle relaxation
Adrenergic Receptors
-Beta 1
- Increase heart Rate
- Increase contractility
- Increase automaticity & conduction
Adrenergic Receptors
-Beta 2
- Bronchodilation
- Arteriole constriction
- Glycogenolysis
Adrenergic’s
-Therapeutic Uses
- Hemodynamic compromise
- Shock, acute CHF, arrhythmias - Bronchospasms, asthma
- Nasal and sinus congestion
Specific Adrenergic drugs
- Epinephrine / norepinephrine
- Phenylphrine
- Dopamine
- Albuterol
- Pseudoephedrine (Sudafed)
Adrenergic
-contraindications / precautions
- Narrow-angle glaucoma
- pheochromocytoma
Use caution w/:
-Heart disease, CAD, arrhythmias, CHF, peripheral vascular disease
Adrenergic’s
-Drug interactions
Any Med that would stimulate the CNS
- MAOI’s
- Alcohol
- tricyclic antidepressants
- theophylline
- Atropine
- Antihistamines
- Any alpha or beta blockers
Adrenergic’s
-Adverse Reactions
- Nervousness/ tremor/anxiety
- Dysrhythmias
- Hypertension
- Cardiac ischemia
- Elevated glucose levels
- pupil dilation
- tissue necrosis
- Headache, insomnia / GI and bladder involvement
Adrenergic
-Implications
- Monitor BP, HR, anginal pain
2. Teach pt’s w/ CAD to watch OTC meds
