what is the reason behind the infusion of intravenous fluid on a patient having cerebral edema?

Think about the relative concentration gradients of specific solutes. You clearly wouldn't infuse something that would cause water to move out of the vasculature into the brain, you would want something that would do the opposite.

interstitial space or 3rd spacing.  Fluid shifts out of vascular space to outside the vessels.  This causes edema, ascites and I think rales.\n\nIt can be seen in fire victims, heart conditions, those who have low albumin.

It sounds suspiciously like a homework question, but here we go...\n\nAt this point, her body is producing significant amounts of catecholamines, hormones such as adrenalin, etc. These hormones cause the heart rate in increase and the blood vessels to constrict. The idea is to get more blood to the vital organs.\n\nThere is a fairly narrow window here to resuscitate the patient. Once the blood pressure starts to fall, she's on a slippery slope in the wrong direction.\n\nThings to add for extra points:\nThe FIRST things that will change in a patient in hypovolemic shock (low blood volume) is a change in her mental status and a drop in urinary output. This is from reduced circulation to the brain and kidneys.\n\nGood luck!

Besides an absolutely normal pathology, you would expect all body fluids to be more concentrated.  This is because the osmotic difference between the surrounding water, and that in the body would cause wate to LEAVE the body.  This CAN happen via the skin, even thought the skin is fairly (but not entirely) waterproof.\n\nRemember that the process of osmosis causes fluids to follow the solute concentration, so a hypertonic solution such as very salty (sea) water would attract fluid, whereas hypotonic solutions (those devoid of solute) would effectively repel water.\n\nBottom line is water would be attracted out of the body tissues and blood into the surrounding sea water.\n\nNOTE THAT SURFGIRLTOGO's ANSWER ABOVE IS NOT CORRECT.  If the salt was INSIDE the red blood cells, the osmotic pressure differential would cause them to lyse and burst.  But as the salt water is OUTSIDE THE BODY, the water would be attracted OUT of the RBC's (and all other 9 types of cells in the blood) causing them to shrivel instead.

Other than heart disease, liver disease, kidney failure, venous insufficiency, severe electrolyte abnormalities.  If the edema is limited to the lower limbs venous compression within the pelvis could be a cause as well.\n\nWhole body edema - anasarca - is seen in end-stage liver disease and in the acute scenarios of fluid overload or severe sepsis.

call the doctor and make sure he/she does not get dehydrated. push fluids.

For one, the man's body heat rising causes most of the symptoms.  Dehydration causes the lack of sweat which in turn causes the body to overheat and slip into heatstroke.\nAs far as the paramedic go I am sure he has his reasons he is obviously trained.  The elctrolyte is essentially water sugar and salt.  Salt will help hold in water.  The man became disoriented because essential his brain was frying in his head.

When I was in nursing school my instructor had a similiar story.. Her son had an accident (I don't remember what) and had 40 staples ear to ear. He had an infection start under the staples from an allergic reaction. They removed the fluid by inserting a tube in the scalp and put him on iv antiobiotics. I hope this helps. Just get to your Dr. ASAP!!   GOOD LUCK AND GET BETTER

"Oral delivery via tablets or capsules is largely inefficient due to exposure of the pharmaceutical agent to the metabolic processes of the body [2]. Therefore, a larger than necessary dose is often required and the maximum effectiveness of the drug is limited. Traditional intravenous (IV) administration is much more problematic. Specificity for IV injectable drugs is often low, necessitating large amounts of a drug be injected into a patient, creating a high concentration of the drug in the blood stream that could potentially lead to toxic side effects"

victorschool1,\n\nThe best first aid for this is pressure, (like an ace bandage) and ice packs.\n\nWhat is the cause of the fluid accumulation? Did you injure yourself, or is it an insect bite, or something else? My first concern would be whether it is something serious.

It isn't a good idea because the wall of that blood vessel is weak and you could burst it. Also, you should consider the reason for the I.V.. If you have been ill, definately wait.

This person needs to See a doctor and must seek some kind of medical care for a diagnosis and hopefully treatment, there are a number of possible causes  for severe edema (swelling)Including parasitic infection of lymph glands, poor circulation, congestive Heart failure, and many more.

be sure to let your MD know.  Could be dependent edema from the increased fluid loads given during the post op time, but could be signs of worse problems, such as a deep vein thrombosis- this could be lethal.  Also you might have CHF congestive heart failure, once again talk with your MD.  After that is done, you should be on a cardio rehab program that teaches proper eating, exercise and medication regiment.

Because that's exactly what hospice is- comfort measures only, and IV fluids aren't considered comfort measures.  They usually only write orders for pain medications to keep patients comfortable in their final days at home. They can give her meds to control her nausea, or you can ask your doctor to have her admitted to the hospital, where she will get IV fluids, but hospice won't do them in the home setting.  That's just not how they operate.

You should ask the doctor or surgeon treating the patient.  I wouldn't even guess unless you told me what part of the brain was damaged.

it constricts your veins..therefore causing you to have less bloodflow to your brain.......

OPPS SORRY, I sent incomplete. Believe it or not, it is generally described as thus: The body wants to have 2/3 of the water inside the cells \n(intracellular fluid) and 1/3 of the water between the cells (extracellular) however a Teacher is probably looking for the technical name of: interstitial fluid
