How many times a month is hemofiltration good?

summary

Hemofiltration is to introduce the arterial blood of patients into a semipermeable membrane filter with good permeability and the same area as glomerular filtration membrane. Because there is a transmembrane pressure gradient between the blood area and the outside of the membrane, when the blood passes through the filter, water and most of the small and medium molecular substances in plasma are filtered out except for proteins and cells, * to achieve the aim of clearing excess moisture and solutes in blood.

How many times a month is hemofiltration good?

Hemofiltration can remove the medium and large molecular toxins in the body. In the process, the blood flow rate is slightly faster than that of hemodialysis. Hemofiltration can also dehydrate, but it cannot be as thorough as that of hemodialysis. Therefore, the amount of drinking water should be controlled as much as possible when doing hemofiltration. Do not do hemofiltration, is to pass the blood biochemical examination, observe whether the index of macromolecular toxins in the body increased. Dialysis patients in principle should do four times a month hemofiltration, which can protect the cardiovascular and cerebrovascular. However, because the blood filter is not included in the scope of medical insurance, so you need to do a blood filter, you have to bear about 500 yuan (the cost varies from place to place). At present, dialysis patients do hemofiltration 1-2 times a month, which can also protect the cardiovascular and cerebrovascular function.

The contraindications of hemofiltration are similar to hemodialysis. 1. Absolute contraindications: intracerebral hemorrhage with elevated intracranial pressure, intractable shock without response to pressor drugs. 2. Relative contraindications: severe visceral active bleeding, severe septic shock, systemic failure caused by advanced tumor, elderly high-risk patients, patients with neuropsychiatric symptoms and unable to cooperate.

During the treatment, closely monitor the operation of the machine and the changes of arterial pressure, venous pressure, transmembrane pressure and blood flow to ensure the balance of body fluid and electrolyte during the treatment. If there is any abnormality, timely handle it, so as to ensure the accurate replacement volume. Closely observe the vital signs of patients and strengthen the communication with patients. Because ultrafiltration and rehydration are very fast, imbalance of replacement volume may occur during treatment, which may lead to hypotension or increase cardiac load. The patients were observed for nausea, vomiting, sweating and other symptoms.

matters needing attention

The patient's life should be regular, his mood must be stable, he must not be too tired, he must also use medicine scientifically, his diet should be reasonable, his stool should be kept unobstructed, and he must tell the doctor about the situation and weight gain before and after hemodialysis, There were no signs of bleeding, changes of condition during dialysis and medication.
