If somebody's carotid or jugular were severed and instead of waiting for the person to bleed out before the ambulance arrived what would be the effects of closing off the artery or vein shut with clamping forceps in an effort to prevent certain bleed out? Would blood be able to take a return path along other pathways, or would fatal pressure build up in the brain due to blockage in one of the jugulars? What would a surgeon do in that situation sans the presence of an operating room and just say, clamping forceps and knife?

If they are bleeding out then their brain still isn't recieving the correct flow anway so in terms of placing pressure on the wound you aren't likely to cause much if any more damange than what has been done already.  Your best bet is to place pressure on the wound while avoiding putting pressure on the airway or placing the head at an odd angle to hurt the neck.  Hopefully you would never be in such a situation, but any reduction in the blood flow out of the body will help, but the faster the ambulance arrived and they could start full treatments the better.  If you're really interested why not take a 1st aid or some emergency med classes in your area?

HEy, I had the laser surgery august 2005 which is suppose to close the main veing and shrink the others to get rid of them Mine are like really bad well i had the surgery and they came back 2 weeks later and lookin even worse now well in Jan.

Hypervenilating removes extra carbon dioxide from the blood.  Our urge to breathe is not driven by lack of oxygen, but by extra CO2 building up; this also affects blood pH, as it forms carbonic acid, so low pH stimulates breathing, too.\n\nThus, the person can hold their breath longer, after hyperventilating.  he / she will not be forced to surface to breathe, to relieve the urge to remove more CO2.\n\nHowever, they will have disturbed their blood pH, which can cause the brain to malfunction, leading to loss of muscular control, and to drowning.\n\nThey might get low on oxygen, too.  Normally, we carry plenty of oxygen in our bodies; even the air we breathe out has plenty of oxygen in it, and can be forced into the lungs of an unconscious person, in "mouth to mouth resuscitation".  IRC the proper name for this is "expired air resuscitation" but I am not sure.

While both answers are technically correct, being a closed loop, the circuit of blood flow cannot really be said to start anywhere, anymore than it can be said to stop at any point.

The flow of blood normally stops when the blood clots, which may be encouraged by direct pressure and reducing the blood pressure in the head by sitting upright with the head tilted forward for about 10 minutes.\n\nPetroleum jelly is sometimes applied to stop the blood from seeping out, but should not be used[citation needed]; as it is petroleum based, it actually further dries out the nasal cavity. Furthermore, it can seep into the lungs and cause a very serious condition known as lipoid pneumonia[citation needed].\n\nIf pressure, ice on the bridge of the nose, application of a vasoconstrictor, or other techniques do not work, a nasal tampon is usually the next step. The nasal tampon stops the bleeding by applying pressure from inside of the nose and is usually kept in for 1-3 days.\n\nChronic epistaxis resulting from a dry nasal mucosa is often treated by spraying saline in the nose up to three times per day. There are also non-petroleum based gels that can be used.\n\nPersistent epistaxis is an indication for urgent medical consultation. Nasal packing, cryosurgery, electrocautery or application of trichloroacetic acid are options that may be used in severe epistaxis.\n\nIt is uncommon to die from bleeding through nosebleeds. However, damage to the maxillary artery can lead to rapid blood loss via the nose and present difficulty in treatment, pressure, vasoconstrictor and rhinocort occasionally proving ineffective. Ligation of the artery, risking damage to the facial nerves, may be the only solution.\n\nA simple treatment for those who have nosebleed on a regular basis is to increase your daily dietary fiber intake. This would make the blood coagulation faster and help quickly stop the hemorrhage.\n\nNevertheless, severe protracted nosebleeds may cause anemia due to iron deficiency.\n\nIf a nosebleed lasts for more than 15 minutes, occurs following a serious injury, or is accompanied by severe blood loss, you should call your doctor or go to the emergency room.

sounds to me like exercise induced compartment syndrome.  the thick tissue surrounding your muscles (fascia) is too tight. as you exercise or walk the muscles engorge with blood but are then squashed by the tight fascia. Leads to a cramp like pains in your calves. due to the history it is unlikely to be a blood clot or anything.  you need to go and see a sports specialist dr. they can do a test where they put needles into the compartments to measure the pressure in there as you walk on a treadmill.  they can then do a small operation to split the fascia to relieve some of the pressure

A cross-clamp is a tool used to close off (clamp) a large artery, often the aorta, during surgery when it is necessary to prevent blood from passing through that vessel. This is what cross-clamp means. Think of it as a large hemastat, it stops blood.\n\nHow is it done? Suppose you have damage to a large artery. I could cross-clamp the artery above the damage, temporarily stopping blood from flowing through the damaged area while I make the repair.  When I'm confident the repair will hold, I release the clamp and watch for leaks.  \n\nHow does it apply to heart surgery?  If repair needs to be done to the heart, it's much, much easier to do this and see what you're doing if the heart isn't full of blood.  But you gotta work FAST.

Ask a doctor about that when you go to the hospital for losing all that blood.\n\nJust kidding I hope.\n\nReally though, it just depends on the health condition of the person and the physical makeup of the person and I don't know you so I can't tell you the effect it would have on you.

The dangers of not doing the surgery is infection, amputation, gangrene, and the infection can spread.  She can ask to try angioplasty to open up the artery first if that would ease her some,  it is much less invasive than the fem. bypass.  But the doctor would have to take into consideration, length, severity, and which arteries are blocked.  I've seen many people go through each of the procedures well.  Just make sure the doctor has done the procedure before.  Hope this helps a little.

It's not the "cutting" so much as the why.  Every self-mutilator I have met has said that hurt, anger sadness, any emotion gets so bad that cutting relieves the pain.  In history doctors used to try to cure diseases by "blood letting"  cutting the patient so the "bad, diseased blood" would be removed from the body.  How deep do you cut?  do you require sutures?  Most cutters are not suicidal, but sometimes accidentally kill themselves by cutting too deep or hitting an artery.  Counseling is not a bad thing, if you get the right person, but you have to want to go or it won't help you.

FIRST OF ALL IF YOU WERE TOLD YOU HAVE PROBLEMS WITH YOUR CAROTID ARTERIES YOU SHOULD BE WORRIED ABOUT GETTING BLOOD CLOTS. SWELLING,RED AND PAINFUL CALF'S ARE A SIGN OF BLOOD CLOTS IN THE LEGS. PLAVIX IS A BLOOD THINNER THAT HELPS TO HAVE THE BLOOD FLOW EASIER AND HELPS TO PREVENT THESE TYPE OF CLOTS. I WOULD ADVISE YOU TO GO TO THE ER, GET MEDICAL ATTENTION AND REQUEST A HOSPITAL SOCIAL WORKER THAT CAN HELP YOU GET GOVERNMENT HELP TO PAY YOUR MEDICAL BILLS.YOU DO NOT HAVE TO BE EMBARRASSED ABOUT CARING FOR YOURSELF,AND I AM SURE THOSE WHO LOVE YOU WILL THANK YOU FOR IT.

Well, the patient will have to follow some rules before going into a surgery. Doctor will tell you not to have any meal for a couple of hours prior to the surgery due to the effect of the anesthetic medicine that will make you feel nauseated. apart from this, the medical personnel will do some skin preparation on you on the part where they will cut you open. It is done to make that area aseptic (clean), so that there will be no secondary infection that will harm you later on. this skin preparation include removing the hair, and wash it using an iodine solution. after the surgery, sometimes, the surgeon will try to wake you up just to see if you're OK. well, sometimes embolism happen during surgery, which can lead to death. lastly, they will put you back to bed, and came over like from every 30 minutes to 1 hour to watch your progress, and most of the time, you are ask to rest.

No.  It isn't worth putting her through the surgery.  Although not without its risks, a carotid endarterectomy is usually successful and done without major complicaitons which will just prolong the inevitable.  If quality of life is as poor as you report there isn't much sense in going though with it.  \n\nSo sorry you are going thought this.

All of the reasons given are valid. Also, the artery walls are thicker, meant to take more pressure, so trying to get a needle into them (smaller, thicker, pulsing, higher pressurized) means more work. They are also deeper, so it is harder to locate them, usually.\n\nI had a doc try to do an arterial blood gas stick on me when I was poisoned once. They were trying to take it from the back of my hand, between the knuckles. Very painful and very very hard to keep the stick. I asked them why they were doing it. They explained that the symptoms I was exhibiting were also the same as carbon monoxide poisoning. I told them I would sign ANYTHING if they would stop trying to stick me there.\n\nI had brought in a bag of the mushrooms we had consumed (jack o'lanterns) thinking they were chanterelles. Projectile vomitting three hours afterward. No mistaking what caused it. Anyway, the liver function came back pretty well in a week.\n\nMy experience with an artery stick.

Blockage from a blood clot is called a "partially occluded retinal vein" in the eye. Sudden symptom are the appearance of a gray foggy spot in the center of your vision, that sometimes fades, but never goes away. Some can be cured with an injection of a kind of steroid. Other causes are more serious. If an artery is affected you would go suddenly blind in that eye. In this case you need to get to the hospital NOW to avoid permanent damage. If you see something that isn't there, it could have to do with a detached retina. If you have any pain or other symptoms, you should seek medical help immediately. Good Luck

Dont take the item out of the body, it will cause internal bleeding and possibly cause more damage than needed..

what happens in atheroschlerosis is that lipids like cholesterol get trapped into the arterial tissue, is attacked by your immune system which causes inflammation and the artery walls thicken, reducing blood flow. clots can also block arteries
