Venesection
Venesection, also referred to as therapeutic phlebotomy or bloodletting, is an individualized medical procedure offered exclusively by Phlebo. Various medical reasons prompt individuals to seek venesection, including conditions like hemochromatosis (iron build-up), polycythaemia (elevated red blood cell concentration), or hormone therapies such as testosterone replacement therapy (TRT).
Venesection involves the insertion of a needle through the skin into a vein, extracting up to 450ml (about two cups) of blood from the body. It is crucial to note that while venesection mirrors the procedure used for blood donation, blood collected during venesection at Phlebo cannot be utilised for donation purposes; it must be appropriately disposed of. Your body will naturally replenish the plasma within 48 hours, with red cells replaced within 4-8 weeks.
Preparation for Venesection:
- Hydration: Ensure adequate hydration by drinking plenty of water in the days leading up to the procedure.
- Comfortable Clothing: Wear loose, comfortable clothing that allows easy access to the arm.
- Medication Review: Inform the phlebotomist provider about any medications or supplements you are taking, as certain medications may affect the procedure.
- Eat Well: Have a light meal before the procedure to avoid light-headedness.
Venesection Procedure:
- Introduction: The phlebotomist will explain the procedure, addressing any concerns or questions you may have.
- Positioning: You will be seated comfortably. The arm chosen for the procedure will be cleaned and prepared.
- Needle Insertion: A sterile needle will be inserted into a vein in your arm. You may feel a brief pinch or sting.
- Blood Collection: Approximately one fifth (about two cups) of blood will be collected for therapeutic purposes.
- Post-Procedure Bandage: After blood collection, a bandage will be applied to the site to prevent bleeding and bruising.
Aftercare Following Venesection:
- Rest: Take a few minutes to rest after the procedure. Sit or lie down as needed.
- Hydration: Drink plenty of fluids, especially water, to help replenish lost volume.
- Avoid Strenuous Activities: Refrain from heavy lifting or strenuous activities on the day of the procedure.
- Observation: Your phlebotomist will monitor you for any immediate adverse reactions.
Possible Side Effects:
- Bruising: Mild bruising at the needle insertion site is common and should subside within a few days
- Light-headedness: It’s normal to feel lightheaded immediately after the procedure. Rest and adequate hydration usually alleviate this sensation.
- Infection from bacteria carried into the bloodstream by the needle.
- Nerve damage, resulting in temporary or permanent numbness, tingling, burning, or pain
Emergency Contact:
If you experience severe symptoms such as persistent dizziness, chest pain, or difficulty breathing after the procedure, seek immediate medical attention or call emergency services.
The frequency of venesections depends on your specific condition, blood count, and your doctor’s recommendation. Some individuals may only require a single venesection on a short-term basis, while others may undergo frequent sessions over an extended period.
