Hypotension is a common complication during dialysis and refers to a decrease in systolic blood pressure >20 mmHg or a decrease in mean arterial pressure of 10 mmHg or more during dialysis with symptoms of hypotension. In mild cases, it manifests as dizziness, palpitations, blurred vision, cold sweat, or no symptoms at all. In severe cases, the symptoms are nausea, vomiting, pallor, profuse sweating, or even loss of consciousness and death, which can be relieved mainly by the following ways: 1. Dietary restriction: Avoid excessive water intake during the interdialysis period. For patients with significant water and sodium retention, enhance dehydration to achieve the ideal dry weight. If there is a rapid decrease in blood pressure, hypertonic fluids can be supplemented immediately to help maintain blood pressure; 2. Change the dialysis frequency: avoid rapid and excessive ultrafiltration by changing the number of dialysis sessions and changing the duration of dialysis; secondly, during the whole process of dialysis, the physician can immediately adjust the amount and speed of dialysis according to the condition; 3. Induced dialysis: Initial dialysis is induced by dialysis to prevent the occurrence of imbalance syndrome; 4. Pay attention to dialysis fluid concentration: the concentration of sodium ions in dialysis fluid is reasonably formulated, such as increasing the concentration values of potassium and sodium ions in dialysis fluid to improve the blood filtration or dialysis membrane, enhance the crystalline component and reduce hypotension; 5. Control blood pressure before dialysis: before dialysis, strive to control blood pressure within the normal range, because the configuration of dialysis fluid, dialysis rate Too fast, too much sodium and water in the body is filtered out, resulting in insufficient blood volume, which can also cause hypotension, for this condition, the patient may not take blood pressure lowering drugs before dialysis; 6, change the position: change the patient’s position, such as the patient is lying on his or her side, lay the patient flat and lower the head to ensure the blood supply to the head; 7, adjust the dialyzer: if hypotension must be terminated dehydration, the temperature of the dialyzer can be reduced, because The lower the fluid temperature of the dialyzer, the less likely it is to cause hypotension.
