Why would someone blood clog a dialysis machine?

Why would someone blood clog a dialysis machine?

Flow rate?: Blood may clot in the dialysis circuit if it isn't flowing fast enough. Blood has a tendency to clot if it 'stands still' or slows down enough. The quality of the 'access' (i.e., usually a fistula) may be a factor here. Additionally, the position of the needles within the fistula may also impact the flow rate. And needless to say, a crimped line will result in clotting if not corrected. Lgromkomd. ...Read more

Dialysis (Definition)

Simple answer is that it is a medical technology used primarily to provide an artificial replacement for lost kidney function in people with renal failure. Hemodialysis remove wastes and excess water from the blood by circulating blood outside the body through an external filter, called a dialyzer. Blood and dialysate flow through in opposite directions and the ...Read more

Why does dialysis cause blood to gel?

Huh?: For very obvious reasons, blood is designed to begin clotting once it leaves the blood vessel as it does in dialysis. This is very well understood and patients undergoing dialysis are given medications to prevent clotting. ...Read more

What is a dialysis machine actually filter out of the blood?

What is a dialysis machine actually filter out of the blood?

Excess "toxins": These include excess water, potassium, phosphate, and a host of other toxins called "uremic" toxins that your body normally gets rid of via the kidneys. However, the machines are not nearly as good as your own kidneys and some toxins do not get removed efficiently. Retention of these toxins causes the typical symptoms of kidney failure. ...Read more

When on dialysis, does blood still go through kidneys at all?

When on dialysis, does blood still go through kidneys at all?

Kidneys on dialysis: Many people on dialysis maintain some level of residual kidney function. This is especially true for peritoneal dialysis. This residual function can make a huge difference in blood pressure management, and also in general health and mortality, so it is important to try to maintain it by avoiding kidney toxins (including medicines) and controlling blood sugar, and salt and phosphorus in the diet. ...Read more

Possibly: If patient is on dialysis, we assume there is little functional kidney left, but kidneys, ureters, and bladder may still develop cancer, especially if patient is a smoker. It should be investigated. ...Read more

What would be the appropriate blood draw for kidney patient on dialysis?

Multiple tests: Every patient on dialysis in us receives monthly blood tests-mandated by cms. They will get complete blood count and iron studies to check for anemia, few tests to measure dialysis adequacy, calcium phosphorus levels, albumin, parathyroid hormone level, hepatitis b tests. In addition, tests may be ordered depending on the patient condition. All these lab results are reviewed by nephrologist monthly. ...Read more

My daughter underwent short term dialysis and now has developed blood clots. Is this normal?

My daughter underwent short term dialysis and now has developed blood clots. Is this normal?

Depends: If the blood clots were in the vein where her dialysis catheter was, this can be a catheter-related thrombosis, estimated to occur with as many as 8% of central lines. If she was on dialysis because of a serious illness where she was bedridden for some period of time, she could have developed DVT in the legs because of inactivity. This is also fairly common (2-15% of pts with critical illness). ...Read more

Is it ethical/legal for blood banks to cite fictional patient cases in an attempt to get donations? Ie, "A dialysis patient needs your blood type..."

Probably not, but...: How do you know they are fictional? I don't think any false advertisement is ethical, but there is definitely a need for blood donors for everyone from cancer patients to dialysis patients to trauma patients. So thanks for donating! ...Read more

It cannot be cure in blood tranfusion only if I don't want a dialysis what other option that I can do? To creatinine 8.5 and hemoglobin 8.5 male 32 yrs

Hi creatinine low Hb: Your kidney impaitment is advanced. Uremic toxins are abundant in your blood and tissues. Your body cannot resist. Anemia is profound. EPO injections can build hemoglobin, but not reverse uremia. Please proceed and plan for dialysis, then kidney transplant. You can be greatly helped. ...Read more

Which prevents water loss from the blood in kidney dialysis for urea?

Dialysis water loss: Patients who are being dialyzed (d) lose water during their d session. The amount of fluid loss can be controlled and they need to have this fluid removed on dialysis so they do not get fluid overloaded and wind up with fluid in their lungs. To answer your question, there is water loss on d which leads to the better health of the patient. ...Read more

Is it normal to have blood in semen with a low sperm count and no motility, when on dialysis?

Uremia and fertility: Many gu diseases cause reduced semen quality & infertility (infec'n, varicocele, renal failure) a recent study compared semen of uremic pts w/nonuremic fertile & infertile males. The sperm motility, survival rate, sperm density, and normal sperm morphology rate were found to be signi´Čücantly lower in uremic patients. Some failed to produce semen and some no sperm at all. May reverse w/transplant! ...Read more

During dialysis why does the subclavian catheter have darker blood than in patients with a fistula?

During dialysis why does the subclavian catheter have darker blood than in patients with a fistula?

Venous blood: A subclavian catheter has only venous, deoxygenated blood returning from the body. A fistula contains oxygenated arterial blood coming from the heart. This is the reason for the bright red blood seen in fistulas. ...Read more

For a dialysis, why is the subclavian catheter has darker blood rather than in patient with fistula?

For a dialysis, why is the subclavian catheter has darker blood rather than in patient with fistula?

Catheter vs fistula: An a-v fistula (avf) is a connection between an artery and a vein, that's why its called an a, for artery, v, for vein, fistula. Arterial blood has more oxygen, making it redder, than venous blood. A subclavian catheter has both blood tubes in the vein, where there is less oxygenated blood, as it does not have any arterial inflow. That's why it has darker blood than an avf. ...Read more

My stepfather is an alcoholic. He is having blood urea and some complications in the kidney. Can it be cured without dialysis?

Impossible to say: With the information you are giving. Dialysis is only needed when kidney failure is occurring and has become severe. Alcohol actually has relatively few complications in the kidney, but if severe liver damage is present, the kidneys can become compromised from toxins not taken out by the liver. Without knowing what kind of kidney problem he has, what creatinine and BUN are, cannot say much. ...Read more

Brother taking 6 different blood pressure meds. Feet swell sometimes. Drs want him to undergo dialysis for bp. Does this sound right?

Brother taking 6 different blood pressure meds. Feet swell sometimes. Drs want him to undergo dialysis for bp. Does this sound right?

Dialysis and BP: Your brother sounds acutely ill. He is on 6 medications, is his BP controlled? I would assume not. The fact that he is edema is his legs is the reason that his physicians want to have him start dialysis. Did they mention his renal function. Perhaps he has renal failure, due to poorly controlled bp, and he needs to start dialysis for that. Ask his doctors why his BP is not controlled on 6 meds. ...Read more

Is it normal for a dialysis patient to have blood in urine?

No: It is never normal to have blood in urine. Although mostly from simple causes it is essential to rule out cancer in the non functioning kidneys as it is much more common than the general population. Treatment is surgical removal of the kidney and is generally curative as these are slow growing tumors. ...Read more

At what serum creatinine and blood urea level dialysis should start?

Onset of dialysis: There are no set levels for BUN and creatinine (c) to start dialysis. The onset of dialysis is determined by a 24 hour urine collection for c clearance. If the patient is a diabetic, dialysis usually starts at a c clearance of 15 ml/min or less. If the patient is a non-diabetic, dialysis starts at a c clearance of. ...Read more
