During Hemodialysis Treatment, Why Can’t The Liquid Level in The Venous Bottle Of The Extracorporeal Circulation Circuit Be Too High?

During hemodialysis, the height of the venous pot in the extracorporeal circulation circuit is a key point that needs to be strictly controlled. As the last link before blood flows back into the patient's body, the height of the venous pot directly affects the safety and effectiveness of dialysis treatment.

The venous pot can collect air in the extracorporeal circulation and provide a buffer time for the operator to remove the air, to avoid interruption of treatment due to the entry of a large amount of air into the extracorporeal circulation.

Reason 1: Prevent blood contamination:

When the liquid level of the venous pot is too high, blood may flow back into the dialysis machine through the connecting tube of the venous pressure test port of the dialysis machine, causing blood contamination. This may cause cross-infection and dialysis machine failure, affecting the safety of subsequent patient treatment.

Reason 2: Easy to observe and operate:

Controlling the liquid level of the venous pot at an appropriate height (such as 2/3 height) helps medical staff to clearly observe the changes in the liquid level and promptly discover and deal with problems such as coagulation and bubbles. Too high or too low a liquid level may affect the observation effect and increase the difficulty of operation.

Reason 3: Comply with clinical operation specifications:

According to clinical operation specifications such as hemodialysis technical operation procedures, the height of the venous pot liquid level needs to be adjusted according to the specific situation, but it is generally not recommended to be too high. A liquid level that is too high may violate the operation specifications and increase the risk of treatment.

The probability of coagulation in the venous pot varies with the height of the liquid level. From the perspective of hemodynamics, when the blood input end pipeline is above the blood liquid level, the blood is prone to form turbulence and coagulation is prone to occur at the wall of the venous pot; when the blood input end pipeline is below the blood liquid level but does not fill the entire venous pot, the upper blood is relatively static, and it is easy to form a fibrin ring at the upper end of the venous pot, causing coagulation in the upper-end venous pot; when the venous pot is full, the blood at the upper end and the blood input end pipeline is relatively static, which is easy to coagulate in the blood delivery end pipeline and is not conducive to observation. Adjusting the liquid level of the venous pot so that the blood input end pipeline is below the blood liquid level can avoid the formation of a gas-liquid contact plane. Maintaining a proper blood level in the venous pot has a certain effect on preventing coagulation in extracorporeal circulation. Dirkes et al. recommend that the blood level in the venous pot be kept at 2/3 level.

However, it is necessary to pay attention to the formation of a "gas-blood" contact surface, which promotes thrombosis;

Handling: Use a sterile syringe to extract saline and connect the venous pressure monitoring tube to push the blood into the venous pot, then use an empty syringe to push the saline into the venous pot, stand up the pipeline, rinse slowly from top to bottom, replace the protective cover and connect the equipment. If the equipment has a liquid level adjustment function, it is more convenient and safe, but if there is blood in the protective cover, replace it immediately.

During hemodialysis treatment, the liquid level of the venous pot in the extracorporeal circulation pipeline cannot be too high to prevent blood contamination, facilitate observation and operation, and comply with clinical operation specifications. Medical staff need to adjust the liquid level according to the specific situation to ensure the safety and effectiveness of dialysis treatment.

How Does Cistanche Treat Kidney Disease?

Cistanche is a traditional Chinese herbal medicine used for centuries to treat various health conditions, including kidney disease. It is derived from the dried stems of Cistanche deserticola, a plant native to the deserts of China and Mongolia. The main active components of cistanche are phenylethanoid glycosides, echinacoside, and acteoside, which have been found to have beneficial effects on kidney health.

Kidney disease, also known as renal disease, refers to a condition in which the kidneys are not functioning properly. This can result in a buildup of waste products and toxins in the body, leading to various symptoms and complications. Cistanche may help treat kidney disease ase through several mechanisms.

Firstly, cistanche has been found to have diuretic properties, meaning it can increase urine production and help eliminate waste products from the body. This can help relieve the burden on the kidneys and prevent the buildup of toxins. By promoting diuresis, cistanche may also help Reduce high blood pressure, a common complication of kidney disease.

Moreover, cistanche has been shown to have antioxidant effects. Oxidative stress, caused by an imbalance between the production of free radicals and the body's antioxidant defenses, plays a key role in the progression of kidney disease. ies help neutralize free radicals and reduce Oxidative stress, thereby protecting the kidneys from damage. The phenylethanoid glycosides found in cistanche have been particularly effective in scavenging free radicals and inhibiting lipid peroxidation.

Additionally, cistanche has been found to have anti-inflammatory effects. Inflammation is another key factor in the development and progression of kidney disease. Cistanche's anti-inflammatory properties help reduce the production of pro-inflammatory cytokines and inhibit the activation of inflammation mandatory pathways, thus alleviating inflammation in the kidneys.

Furthermore, cistanche has been shown to have immunomodulatory effects. In kidney disease, the immune system can be dysregulated, leading to excessive inflammation and tissue damage. Cistanche helps regulate the immune response by modulating the production and activity of immune cells, such as T cells and macrophages. This immune regulation helps reduce inflammation and prevent further damage to the kidneys.

Moreover, cistanche has been found to improve renal function by promoting the regeneration of renal tubes with cells. Renal tubular epithelial cells play a crucial role in the filtration and reabsorption of waste products and electrolytes. In kidney disease, these cells can be damaged, leading to damaged renal function. Cistanche's ability to promote the regeneration of these cells helps restore proper renal function and improve overall kidney health.

In addition to these direct effects on the kidneys, cistanche has been found to have beneficial effects on other organs and systems in the body. This holistic approach to health is particularly important in kidney disease, as the condition often affects multiple organs and systems. che has been shown to have protective effects on the liver, heart, and blood vessels, which are commonly affected by kidney disease. By promoting the health of these organs, cistanche helps improve overall kidney function and prevent further complications.

In conclusion, cistanche is a traditional Chinese herbal medicine used for centuries to treat kidney disease. Its active components have diuretic, antioxidant, anti-inflammatory, immunomodulatory, and regenerative effects, which help improve renal function and protect the kidneys from further damage. , cistanche has beneficial effects on other organs and systems, making it a holistic approach to treating kidney disease.
