What is the cause of blood vessel spasm in hemostasis?
"Initiated by endothelial injury and caused by local and humoral mechanisms". Other helpers such as thromboxane, platelets releasing prosaglandin and neural reflexes all aid in vasoconstriction of the vessels. (Porth & Matfin, 2009)
Why mix epinephrine with a local anesthetic?
It prevents the anesthetic from being systematically absorbed. The local anesthetic will cause vasodilation, and this can push some of the drug into systemtic circulation. Epinephrine causes vasoconstricton and keeps the anesthetic drug in the area where it was administered.
If a patient has open angle glaucoma are local anesthetics with epinephrine safe to use for dental treatment?
Epinephrine should be safe in open angle glaucoma. It causes vasoconstriction, and results in a reduced amount of aqueous humor production.
Why does hypothermia cause vasoconstriction?
because your body tries to reduce heat loss to the surroundings so the blood vessels constrict so the blood stays at the core of the body rather than reach the skin where heat will easily be lost to the surroundings.
What initinates vasoconstriction and vasodilation?
Vasoconstriction is primarily initiated by the release of vasoconstrictor substances such as norepinephrine and angiotensin II, which cause smooth muscle contraction in blood vessel walls. Conversely, vasodilation is triggered by factors like nitric oxide, prostacyclin, and certain hormones, leading to the relaxation of smooth muscles and widening of blood vessels. Additionally, local metabolic signals such as increased carbon dioxide and decreased oxygen levels can also prompt vasodilation in specific tissues. Thus, these processes are regulated by a complex interplay of neural, hormonal, and local factors.
Why did the leblanc process caused a great deal of pollution to the local area?
because it release harmful gasses that causes our atmosphere to be destroyed.
What would lead to vasoconstriction of an arteriole?
Vasoconstriction of an arteriole can be caused by signals from the sympathetic nervous system, circulating hormones like epinephrine and norepinephrine, or local factors such as low oxygen levels or increased levels of certain molecules like endothelin. It results in the narrowing of the arteriole, which increases peripheral resistance and raises blood pressure.
What produces vasoconstriction?
Peripheral vasoconstriction is the tightening of the blood vessels, particularly the arteries. It is caused by smoking, drinking alcohol and coffee, as well as the intake of medicine such as antihistamine.
What is local myogenic spasm?
Muscle Spasm, this would be referring to when a blood vessel is broken, the response to fix it would be vasoconstriction. A myogenic spasm would aid in the loss of blood by briefly constricting the muscle where the broken blood vessel is located.
What Chemical that causes local blood vessels to dilate?
This substance is called histamine.
Can I donate platelets after taking Aleve?
Yes, you can donate platelets after taking Aleve (naproxen), but it's advisable to wait at least 48 hours after your last dose. Aleve is a nonsteroidal anti-inflammatory drug (NSAID) that can affect platelet function temporarily. Always check with your local blood donation center for their specific guidelines and recommendations regarding medication use prior to donation.
Where is Lacrosse gas release 2016?
The Lacrosse gas release incident in 2016 occurred in the Lacrosse area of Wisconsin, USA. It involved the accidental release of natural gas from a pipeline operated by a local utility. The incident raised concerns about pipeline safety and emergency response measures in the region. Following the release, investigations were conducted to assess the causes and implement necessary safety improvements.
