What are side effects of 1/4% saline injection to treat hypovolemia??


If done by an experienced professional, there should be no side effects at all...only that you'll feel better afterwards. :)  (+ info)

Can too much sleep cause hypovolemia?


I was researching orthostatic hypotension on wikipedia and it said one of the causes to that is hypovolemia which can be caused by blood loss and many other things. The one cause that caught my attention was bed rest. Is Wikipedia inaccurate on this? If not, can someone expain to me how it causes hypovolemia?
----------

I don't see how that makes sense either. Hypotension could certainly occur during sleep but I certainly don't think it would be caused by hypovolemia, I mean you don't lose any fluid when you sleep which is a necessary feature of it. As an aside, hypovolemic shock basically occurs when you lose enough blood so that your blood pressure decreases drastically enough so that your heart can't pump blood, and therefore oxygen to the places it needs to go and tissues die (e.g. brain) from lack of oxygen. I have no idea what Wikipedia is talking about here then. However, note that if you do go into hypovolemic shock you will eventually pass out due to that decreased blood pressure because oxygen isn't circulating to your brain in your blood.

I mean, your BP could drop orthostatically during sleep due to other factors, such as decreased heart rate and systemic vasodilation but certainly NOT from fluid loss....unless a ninja comes and chops your balls off while you're sleeping. That would be awesome and suck at the same time.  (+ info)

Can tuberculosis cause hypovolemia?


Since tuberculosis causes someone to cough up blood, I was wondering if it could lead to low blood volume.

In Hypovolemia is the blood too thick or too thin?


I know there is a depletion in total blood volume does this result in the blood becoming to thick or too thin.

Thank you for your answers ( :
----------

By your definition, the blood is too thick. Strictly speaking hypovolemia is a lack of blood plasma, but normal levels of blood cells. It can be caused by dehydration (not drinking enough, this can happen to the elderly) , internal bleeding, massive external bleeding, chronic diseases and traumatic accidents.  (+ info)

how does someone die 8 hours later of hypovolemia in the the emergency room!?


i am 18 years old and my mother passed away when i was 13. dec. 17th 2003, her and her boyfriend robbed a gas station in lufkin, Texas. during the get away chase, they crashed head on with another car in a residential neighborhood. my mom was on the passengers side and wasnt wearing her seatbelt so she was thrown from the car. then the cop that was chasing them ran her over. on her death certificate it says that the main cause of death was hypovolemia. then a pelvic fracture with hemorrhage. and the last two causes were a splenic laceration and respiratory failure. she died 8 hours after the accident and she was air lifted to the hospital. now how does someone die 8 hours later in the emergency room? couldnt they have given her blood? isnt that why we donate our blood to these blood banks? in those 8 hours couldnt someone have stopped the bleeding? checked for internal bleeding? something!? ive watched shows where people have gotten shot in the head and still lived! i just need someone to clear somethings up for me... any e.r. doctors that can help me understand this???
----------

I'm a pharmacist. I'm sorry for your loss. Hypovolemia just means a loss of blood and fluids. It sounds like you mother had traumatic internal bleeding. There are complications with such trauma, mainly stress on the heart. Although hypovolemia was listed as the cause of death, it was probably several factors that contributed to her death.  (+ info)

can donating blood lead to kidney failure?


I was reading that a person can go into kidney failure from hypovolemia due to blood loss. Can a person who has donated a pint of blood go into kidney failure if they don't drink enough following donating, and if so, how long could this take to occur?
----------

No, it's completely safe to donate blood.   (+ info)

in cases involving a patient complaining of chest pain and /or difficulty in breathing, the EMT-Basic should..


in cases involving a patient complaining of chest pain and /or difficulty in breathing, the EMT-Basic should suspect what?

a) cardiac problems
b) trauma
c) tracheal deviation
d) hypovolemia
----------

would start with cardiac, unless of course there has been trauma involved... (ex: car wreck, fights, falls, etc) the others could be possible causes too, but you would start with the most common, and then do your assessment, to rule out other causes....  (+ info)

what factors determine whether nasal cannula or facial mask is used for supplementation oxygen?


This is a case of blunt forced trauma recieved from a motorcycle accident that resulted in rib fracture and hypovolemia.
----------

The patients o2 stat would determine his oxygen needs! THeres also some blood work and a physican assessment to determine what he needs.  (+ info)

Decreased or Increased Cardiac Output in Preeclampsia?


My groupmates and I have been debating for a while now the pathophysiology of preeclampsia in of course, women.

It is quite troublesome because some of their research show that hypovolemia and decreased cardiac output accompanies preeclampsia while my own research show that hypervolemia causes edema while at the same time increases extracellular fluid increasing stroke volume thus increasing cardiac output and then leads to hypertension.

What do you guys think is right?
----------

Resarch indicates that you may both be right -

WedMD notes, "Changes in virtually all organ systems occur in preeclampsia-eclampsia. Intense vasospasm occurs probably in response to the higher sensitivity to all endogenous pressors, particularly angiotensin II. The hypervolemia seen in normal pregnancy does not occur. Decreased intravascular volume and hemoconcentration occur at least in part because of endothelial cell damage that promotes leakage of fluid and protein from the intravascular to the interstitial space. The leakage causes contraction of the intravascular space and expansion of the interstitial space (ie, edema)." (1)

However, it has been noted that hypovolemia exists in patients with preeclampsia with the exception of women with pyelonephritis. (2)

Also "... It is notable that women with occult or undiagnosed renal disease may present with apparently new-onset hypertension and proteinuria in pregnancy that may mimic preeclampsia. Obtaining a careful history, physical examination, and laboratory evaluation may clarify the diagnosis." (1)

So, while the traditional view is that hypovolemia presents in patients with preeclamsia, there may be other pre-conditions in your patients which resulted in the hypervolemia. With the human body, the diagnosis is never cut and dried.... Good luck with your debates.

Check out the research at medline, nih.org. hypertension.com, etc - there are some interesting studies regarding cardiac output and preeclampsia.
