Low blood pressure after hemodialysis has to be differentiated into different situations. The most common reason is that the dry weight is set low, resulting in the post-dialysis weight being lower than the actual dry weight, which puts the body in a relatively ischemic state, with insufficient effective circulating blood volume, thus resulting in low blood pressure, and then it is necessary to appropriately adjust the dry weight upward. Low blood pressure also occurs after dialysis when the ultrafiltration set during dialysis is too large and exceeds the body’s tolerance, leading to ultrafiltration too fast during dialysis and low blood pressure at the end of dialysis. In both cases, oral sugar saline is needed to replenish fluids, and if the blood pressure cannot be effectively restored by oral intake, it is necessary to set up intravenous channels, perform rehydration, volume expansion and other treatments, and if the blood pressure still cannot be restored, it is necessary to be hospitalized and adjusted. There is another reason, is caused by cardiovascular factors, such as the body is in a state of ischemia, induced ischemic heart disease, such as acute infarction, this time will generally be accompanied by chest tightness, chest pain, shortness of breath and other manifestations, you need to go to the emergency room immediately, improve the relevant examination to clarify, and hospitalized cardiovascular specialist line rescue treatment.
