Can you tell me how anaphylaxis cause circulatory shock?

Can you tell me how anaphylaxis cause circulatory shock?

Yes: Due to the release of histamine and other molecules, the blood vessels become overly leaky allowing blood to exit the blood vessels and distribute in tissue. This does not leave enough blood left inside the vessels to adequately bring oxygen to the brain, heart and lungs. ...Read more

Anaphylactic Shock (Definition)

Anaphylaxis is a severe, whole-body allergic reaction to a chemical that has become an allergen. After being exposed to a substance such as bee sting venom, the person's immune system becomes sensitized to it. When the person is exposed to that allergen again, an allergic reaction may occur. Anaphylaxis happens quickly after the exposure, is severe, and ...Read more

Could you explain physiologically what is happening in the body during anaphylactic shock?

Could you explain physiologically what is happening in the body during anaphylactic shock?

Complex: The pathophysiology of anaphylaxis is complex. It involves the release of many biologically potent mediators from cells like mast cells and eosinophils. These in turn act on tissues like blood vessels causing dilation with a resultant drop in blood pressure and smooth muscles throughout the body such as in the bronchioles causing them to constrict. Multiple organs are affected. ...Read more

What happens when you use an epi pen without having anaphylactic shock?

What happens when you use an epi pen without having anaphylactic shock?

Waste 100 bucks: An amazingly safe medication. In the seventies we used Epinephrine to treat acute asthma attacks giving kids 3 doses in 40 minutes. Sometimes they had nausea & vomiting. Sometimes they'd get a little hyper. The nausea & vomiting could also have been due to asthma itself. Anyway, expect slight but brief rise in pulse, mild muscle jitteriness, heightened alertness. All resolve in 30 minutes. ...Read more

Has anyone ever gone into anaphylactic shock and died in a couple of minutes?

Has anyone ever gone into anaphylactic shock and died in a couple of minutes?

Yes...: This can happen if the airway is quickly and severely compromised. This is why it is important to have an epi pen available for anyone who has had this reaction. See your doctor so this can be prescribed. It can be life-saving! ...Read more

For how long after anaphylactic shock we expect after effects & what after effects?

1-2 days: Developing anaphylactic reactions involves many organs, depending how severe the reaction was. If it was treated as out patient and did not need intubation, usually a few hours to a day the person feels tired. If the person was ill enough to be intubated and admitted to the hospital, the time to resuscitation is key for brain preservation. So it is variable. ...Read more

How to know if I had a anaphylactic shock or not, how to know if I should use epi-pen?

How to know if I had a anaphylactic shock or not, how to know if I should use epi-pen?

Hard to know: The best way to prove anaphylaxis is to demonstrate elevated tryptase levels (blood test) at the time of the reaction. Often, this test is not done as symptoms and timing with suspected trigger is enough to diagnose and treat. If one suspects they have had an anaphylactic reaction (now resolved), then they should urgently discuss with a physician to see if epi prescription is needed. ...Read more

Can you got into anaphylactic shock from perfume and if so how long does it take for the symptoms to show up?

Probably not: Anaphylaxis due to allergen trigger usually requires an antibody to have been made in the past and present in sufficient quantity at the time of exposure (peanut allergy for example). Antibodies to perfumes generally do not exist. An irritant reaction, however, can occur and can cause a reactive lung problem or vocal cord spasm producing somewhat similar symptoms. Go to ER if ever in doubt. ...Read more

Anaphylactic shock from spring allergies? Is that possible?

Anaphylactic shock from spring allergies? Is that possible?

Unlikely: Anaphylaxis is usually caused by stinging insects, foods, or medications. Spring allergens in the U.S. Are usually tree pollens. A systemic reaction to airborne pollens would be exceedingly unusual. ...Read more

Can flowers cause anaphylactic shock?

Can flowers cause anaphylactic shock?

Yes; pollen allergen: It may not be the flowers, but the pollen within them, that caused the allergy. Anaphylactic shock is a severe allergic reaction where the body reacts to a harmless substance (like pollen) by over-producing histamine & starting an exaggerated immune response. In some cases, this causes an unsafe drop in blood pressure (shock). Emergency treatment with epinephrine & steroids (immunosupressant). ...Read more

How to know if I had an anaphylactic shock?

Some tips: When you have trouble breathing due to obstruction in the tongue or throat swelling or airway obstruction (asthma), when you are fainting due to low blood pressure, or when you are having abdominal cramps, vomiting, and/or diarrhea, for no known reason, then anaphylaxis is a possibility. Over 90% of anaphylaxis is associated with itching, flushing, and/or hives and this is important to remember ...Read more

What happens when you get anaphylactic shock?

What happens when you get anaphylactic shock?

Bad stuff: Anaphylaxis causes dilatation & leaking of blood vessels. That causes swelling of membranes, particularly in the respiratory tracy. This compromises organs depending on their blood &oxygen supply. Soon blood pressure drops, then organ failure follows if anaphylaxis is left untreated. Finally death ensues. ...Read more

How to know if I have an anaphylactic shock attack?

You'd know: Anaphylaxis is caused by exposure to an antigen which elaborates an exaggerated response from the body. This results swelling of the airway tissues, blocking them, wheezing in the lungs and generalized body swelling. If it happened to you, you'd not forget it. It can be treated with Epinephrine and steroids which reduce the swelling. ...Read more

What to do if someone goes into anaphylactic shock?

EPIPEN (epinephrine) and 911: Anaphylactic shock is a medical emergency. If an Epipen is available inject immediately. Then call 911. The patients swells up, their airways close (from edema or swelling), they may start getting red (from hives and histamine release) etc. Stay with the patient. If recognized early may be able to have patient take some Benadryl (diphenhydramine) and/or Prednisone to ward off some of the disastrous reactions. ...Read more
