what are the reasons of low blood pressure occurred in dialysis
Treatment of chronic kidney disease during hemodialysis, dialysis patients hypotension onset rate is relatively high, then the reason the treatment of chronic kidney disease dialysis hypotension what is it? Chronic kidney disease patients on dialysis hypotension presenting more conditions, the onset of dialysis hypotension often exhibit some prodromal symptoms, such as dizziness, lightheadedness, nausea, vomiting, increased heart rate, etc., dialysis patients also showed a sudden drop in blood pressure without symptoms of hypotension, so during dialysis, blood pressure should be regularly and timely treatment, or will increase the patient's condition, here we take a look at what causes dialysis hypotension is?

Unstable vascular function in hemodialysis patients with chronic kidney disease: the room Britain, pericarditis, endotoxin, infection and bleeding easily lead to hypotension. Most hypotension during dialysis and excessive dehydration make sharp decline in blood volume related, in a very short period of time excessive ultrafiltration, causing cardiac output and the output was reduced, due to the ultrafiltration error estimate; dialysis patients to more The weight of the water overstatement; poor venous vascular access, dialysis venous hypertension caused the positive pressure, excessive ultrafiltration volume, causing a lack of blood volume, but also more common in dialysis before there is a lack of blood volume, as eating less sodium diet, nausea, vomiting, blood pressure medication and therapy vasodilator agents.

Treatment of chronic kidney disease, dialysis significant weight gain: weight landed in a timely blood volume more than 5% beyond the proper weight before folding, easy to attack low blood pressure, thus increasing the period between dialysis weight should be controlled below 4%. Dialysate sodium concentration is below the long-term plasma, resulting in lower serum sodium, serum concentrations soaked landing, fluid into the cell, so that hypovolemia. Most episodes of hypotension caused by an excess of ultrafiltration in the beginning 1 hour after dialysis, ultrafiltration when a certain amount without additional liquid, due to the dialysis membrane and allergic toxins caused by hypotension, the earlier presentation, over several elements exist , the timing of the onset of hypotension increases.

The course of treatment of chronic kidney disease on dialysis, you should avoid excessive ultrafiltration: the more accurately the body eliminate excess water can not exceed 1% per hour ultrafiltration dialysis patient body weight. Adjusted periodically dialysis patient's weight, the staff person said dialysis patient's weight and accurate records. 140 with an ordinary sodium 14anm01 / L of dialysate, dialysis raised a start to the electrical conductance of sodium 143 a l45mmol / L, acute hypotension, quickly enter high sodium water and hypertonic glucose solution, but it can cause excessive dialysis weight gain or worsen heart failure patients. Improve heart function: abundant dialysis three times a week.
