What Causes Low Blood Pressure in Dialysis
Dialysis is one of most important treatments for patients in the end stage of renal failure. Even though adequate dialysis can prolong patients’ life expectancy, many complications many appear in the process, among which low blood pressure is very common. Here i am going to tell you what causes low blood pressure.
Effective blood volume declines
The blood flows out of the body increases suddenly that makes blood thicken and the fluid outside the capillaries sostenuto moves into capillaries. When ultrafiltration rate beyond filling rate, low blood pressure appears. If the total volume of water filtered is more than the patient should lose, low blood pressure must occur.
Autonomic neuropathy often appears in patient with chronic renal failure. It causes the patient’s baroceptor and sympathetic nerve endings can not work well, so the blood pressure can not be regulated appropriately.
The secretion of atrial natriuretic peptide
Atrial natriuretic peptide is a kind of hormone that can promote the filtration of fluid. Edema in renal failure patient can cause the secretion of atrial natriuretic peptide, but dialysis can not clean it up, and then too much fluid secreted is more likely to cause low blood pressure.
Hyoxemia associated with dialysis is another reason for low blood pressure. Some patients present the decrease of partial pressure of oxygen in their dialysis, then they have low blood pressure.
The diseases from cardiac muscle cause heart problems, which lead to heart beat reducing and make the blood pressure lower.
The incorrect use of antihypertensive drugs in dialysis
When high blood pressure appears in dialysis, doctor usually prescribe antihypertensive drugs. However, if using these antihypertensive agents incorrectly, blood pressure will decline abnormally.
Low blood pressure is a common symptom in dialysis. If uncontrolled effectively, it may cause life-threatening complications. If you are on dialysis and suffer from low blood pressure, you should make clear the causes and accept proper treatment timely. Only in this way, you can avoid further healthy problems.
