Study Set Content:
is one of the strategies to treat chronic orthostatic hypotension, and drugs activating a receptors can be used for this purpose.
Increasing peripheral resistance
is used for this indication
Midodrine
have been used in the temporary emergency management of complete heart block and cardiac arrest.
Isoproterenol and epinephrine
may be useful in cardiac arrest in part by redistributing blood flow during cardiopulmonary resuscitation to coronaries and to the brain.
Epinephrine
However,____ are both safer and more effective in heart block and should be inserted as soon as possible if there is any indication of continued high-degree block.
electronic pacemakers
injection is used as a pharmacologic cardiac stress test. Often used in patients unable to exercise during the stress test.
Dobutamine
augments myocardial contractility and promotes coronary and systernic vasodilation.
Dobstamine
These actions lead to increased heart rate and increased myocardial work and can reveal areas of in chemia in the myocardiam that are detected by
echocardiogram or nuclear medicine
applied topically in nasal packs (for epistaxis) or in a gingival string (for gingivectomy)
Epinephrine
is still sometimes used for nasopharyngeal surgery because combines a hemostatic effect with local anesthesia.
Cocaine
Occasionally, cocaine is mixed with ____ for maximum hemostasis and local anesthesia.
epinephrine
One of the most important uses of sympathominetic drugs is in the therapy of
bronchial asthma.
albuterol metaproterenol, tertutaline)
Beta 2-selective drugs
Short acting preparations can be used only transiently for acube treatment of
asthma symptoms
For chronic authma treatment in adults, long-acting @ 2 agonists should only be used as an addition to steroids because they may increase
morbidity used alone
and related imediate (type gt-mediated reactions affect both the respiratory and the cardiovascular systems
Anaphylactic shock
The syndrome of treechospasm, mucous membrane congestion angioedema, and severe hypotension usually responds rapidly to the parenteral administration of epinephrine, 0.3-0.3 me 10.3-0.5 mL of a 1:1000
epinephine solutoel
may be the preferred route of administration
Intramuscular injection
(both H1 and H2 receptor antagonists may be useful as secondary theory
Chacocorticoids and antihistamines
agrees of choice in anaphytas presumably because episeplvine activates 01 and 2 receptors, all of which be important in revering the pathophysiologic processes underlying anaphylaxis
Epinephrine
