During dialysis, the incidence of hemodialysis is very high. Especially for CKD patients in EDRF, they are more likely to present hypotension. Dialysis hypotension usually presents some premonitory symptoms such as faint, anxiety, chest distress, cold sweat, nausea and vomiting heart rate increase. Few Chronic Kidney Disease (CKD) patients taking dialysis may have no premonitory symptoms, their blood pressure can decrease all of a sudden. Therefore, it is quite requisite to monitor the blood pressure during the dialysis. Once patients present above abnormality, they need to lie on their back and get proper treatment.
The main causes of dialysis hemodialysis are as below:
1. Insufficient Blood volume
During the dialysis, dehydration usually occurs which can cause blood volume decline rapidly.
2. Using dialysis liquid with low-sodium for long
The content of sodium in dialysis liquid is lower than that of plasma so that more blood sodium leave plasma and plasma osmosis pressure get decreased. Excess body fluid accessinto cells, resulting blood volume decline.
3. Put on weight all of a sudden during the dialysis
4. unstable blood vessel function:
Endotoxin, Pericarditis infection bleeding, can cause hypotension
5. Autonomic nerve obstruction
Therefore, it is quite requisite to monitor the blood pressure during the dialysis. Once patients present above abnormality, they need to lie on their back and get proper treatment.
