What is Hemoperfusion?
Hemoperfusion is a treatment technique in which large volumes of the patient's blood are passed over an adsorbent substance in order to remove toxic substances from the blood. It deals with all the small and middle sized toxins, as well as a few large sized wastes in the blood.
What are the functions of Hemoperfusion?
• Remove nephrotoxic drugs or poisons from the blood in emergency situations (A nephrotoxic substance is one that is harmful to the kidneys.)
• Provide supportive treatment before and after transplantation for patients in
• Eliminate waste products from the blood in patients with kidney disease
• It is more effective, compared with other treatment, in eliminate some specific wastes in the blood, especially those bind to proteins in the body. This substance rarely is dissolved in water.
What are the side effects of Hemoperfusion?
The side effects of hemoperfusion are similar with those of hemodialysis, including:
- blood clotting
- destruction of blood platelets
- blood pressure drop
- equipment failure
What are the features of Hemoperfusion?
- Hemoperfusion plays a significant role when it comes to removing toxic drugs or poisons from the blood in emergency situations.
- It is easy handling. A hemoperfusion system can be used with or without a hemodialysis machine.
- Hemoperfusion is able to clear toxins from a larger volume of blood than hemodialysis or other filtration methods; it can process over 300 mL of blood per minute.
- It has the character of high efficiency. Outstanding adsorption capacity is achieved using 300g of hemoperfusion-grade activated charcoal.
What are the Hemoperfusion facts?
- hemoperfusion may remove as much as 80% of the drug found in the blood plasma.
Dos and don'ts of Hemoperfusion
- The hemoperfusion system is prepared by sterilizing the cartridge containing the sorbent and rinsing it with heparinized saline solution.
- Before the tubing is connected to the catheters in patient's arm, pressure tests should be performed.
- When talking about the preparation, your doctor may suggest you not cleanse your skin on the inside of the arm with and antiseptic solution.
