What does CVVH mean in SURGICAL
CVVH stands for Continuous Veno-Venous Haemofiltration, a blood purification technique used in critical care settings for patients with acute kidney injury (AKI) or fluid overload. It involves removing waste products, toxins, and excess fluid from the blood continuously.
CVVH meaning in Surgical in Medical
CVVH mostly used in an acronym Surgical in Category Medical that means Continuous Veno-Venous Haemofiltration
Shorthand: CVVH,
Full Form: Continuous Veno-Venous Haemofiltration
For more information of "Continuous Veno-Venous Haemofiltration", see the section below.
Principle of Operation
-
Blood Withdrawal:** Blood is withdrawn from a central vein into a filtration circuit.
-
Filtration:** The blood passes through a semipermeable membrane that separates waste products and excess fluid from the blood cells and proteins.
-
Ultrafiltration:** Excess fluid is removed from the blood through the membrane, reducing fluid overload.
-
Replacement Fluid:** A replacement fluid is infused into the patient to maintain blood volume and electrolyte balance.
-
Return of Blood:** The filtered blood is returned to the patient through another central vein.
Advantages
- Continuous: Provides continuous blood purification, ensuring constant removal of waste products and fluid.
- Efficient: Effectively removes waste products and excess fluid without significant loss of blood cells or proteins.
- Hemodynamically Stable: Maintains blood pressure and volume, making it suitable for critically ill patients.
- Biocompatible: Uses biocompatible membranes to minimize patient reactions.
Indications
- Acute kidney injury (AKI)
- Fluid overload resistant to diuretics
- Severe electrolyte imbalances
- Sepsis-induced acute kidney injury
- Drug overdose requiring continuous blood purification
Essential Questions and Answers on Continuous Veno-Venous Haemofiltration in "MEDICAL»SURGICAL"
What is Continuous Veno-Venous Haemofiltration (CVVH)?
CVVH is a blood purification technique used to remove waste products, toxins, and excess fluid from the body. It is often used when the kidneys are not functioning properly or when other methods of dialysis are not feasible.
How does CVVH work?
CVVH involves continuously filtering blood through a semi-permeable membrane. The blood is pumped from a vein into a dialyzer, where it flows past the membrane. The waste products and excess fluid pass through the membrane, while the cleaned blood is returned to the body through a vein.
When is CVVH used?
CVVH is primarily used in patients with acute kidney failure, but it can also be employed in cases of:
- Fluid overload
- Electrolyte imbalances
- Drug overdoses
- Severe sepsis
What are the benefits of CVVH?
CVVH offers several benefits, including:
- Continuous removal of waste products and excess fluid
- Hemodynamic stability
- Preservation of residual kidney function
- Improved patient comfort
What are the risks of CVVH?
As with any medical procedure, CVVH carries certain risks, such as:
- Bleeding
- Infection
- Hypothermia
- Hypotension
- Fluid overload
Final Words: CVVH is a valuable blood purification technique in critical care, providing continuous removal of waste products and excess fluid while maintaining hemodynamic stability. Its applications extend to various conditions requiring intensive renal support and fluid management.
