Contraindications of hemodialysis

For some patients with renal failure, it is very important to determine whether they have any contraindications to hemodialysis. In fact, the contraindications of hemodialysis depend on the patient's own adaptability. For example, the initial contraindications may be mild anorexia, nausea, vomiting, etc. If the condition is more serious, renal failure may occur, and this mainly depends on whether there is bleeding, shock, etc.

Hemodialysis, abbreviated as hemodialysis, is also commonly known as artificial kidney or dialysis. It is a type of blood purification technology. It uses the principle of semipermeable membrane to remove various harmful and redundant metabolic wastes and excess electrolytes in the fluid out of the body through diffusion, so as to purify the blood and correct the balance of water, electrolyte and acid-base.

Instruments: Because renal dialysis relies on instruments for extracorporeal blood circulation, there is a certain risk to the patient, so the grade and safety factor of the instrument are very critical. Some large hospitals mostly use imported carbonation machines (such as the Swedish brand Campbell) and are equipped with full-time maintenance engineers. Some hospitals use acetic acid machines, which are obsolete models and can easily cause headaches and hypoxia in patients.

Requirements for doctors: Doctors must develop individualized plans based on the dialysis patient's condition. It is understood that some large hospitals also have regulations for regular follow-up and will adjust the patient's dialysis plan in a timely manner according to changes in the patient's condition.

Requirements for nurses: It is reported that in the United States, nurses doing renal dialysis must have more than 5 years of surgical clinical experience. Experienced nurses can take good care of the fistula of renal dialysis patients and keep it open for a long time.

Consumables: The state stipulates that disposable consumables (such as dialyzers) should be used during dialysis. However, due to economic reasons, most hospitals allow patients to use reusable dialyzers. Some large hospitals generally stipulate that it should not exceed 6 times and are equipped with advanced reuse machines. This reuse machine can tell whether the dialyzer meets the reuse indicators.

Dialysis time: A dialysis session should generally last about 4 and a half hours. However, some hospitals perform dialysis on three patients a day. In order to schedule the shifts, they shorten the session for each patient by half an hour. This way, toxins will remain in the patient's body.
