Study Notes
Introduction to Phlebotomy
- Phlebotomy is the process of drawing blood from a vein.
- It's a crucial procedure in healthcare, used for various diagnostic and therapeutic purposes.
- Trained professionals, typically phlebotomists, perform the procedure.
- Accurate and sterile techniques are essential to prevent complications.
Purpose of Phlebotomy
- Diagnostic testing: Identifying diseases and conditions by analyzing blood samples. This includes blood counts, chemistry panels, hormone levels, and other tests.
- Monitoring treatment effectiveness: Track the effects of medication and therapies on the body by analyzing blood samples.
- Transfusions: Providing blood or blood products to patients needing them.
- Research: Contributing to scientific research on various diseases through blood sample analysis.
- Therapeutic procedures: Removing excess blood in certain medical conditions.
Pre-Procedure Considerations
- Patient identification: Verification to ensure the correct patient is receiving the blood draw. This is a critical step to avoid mistakes.
- Patient history: Collection of relevant medical information, including any allergies or conditions that might affect the procedure.
- Informed consent: Explaining the procedure, risks, and benefits to the patient, obtaining their agreement to proceed.
- Assessing patient comfort: Making sure the patient is comfortable and able to cooperate during the procedure.
- Evaluating the patient's vein accessibility: Assessing the veins before the procedure to select a suitable vein.
Procedure Equipment and Supplies
- Proper gloves: Essential for preventing contamination and protecting the healthcare provider.
- Sharps container for disposal: Safe disposal of needles and other sharp objects.
- Tourniquet: Used to temporarily constrict blood flow in the vein, making it easier to locate.
- Alcohol swabs: Use for proper antiseptic cleaning of the venipuncture site.
- Sterile gauze on hand for after draw.
- Needles and syringes (different sizes depending on the sample needs).
- Tubes for blood collection (labelled with appropriate anticoagulants or additives).
- Labels and tubes for adequate sample identification.
Steps of the Phlebotomy Procedure
- Preparing the patient and site: Explain the procedure to the patient and appropriately prepare the skin.
- Applying the tourniquet: Apply loosely and not too tightly.
- Selecting and prepping the vein: Identify a suitable vein by palpation, avoiding any bony prominences or fractured veins.
- Inserting the needle: Precise insertion with proper angle is needed.
- Collecting the blood: Correctly filling the tubes with the required volume of blood.
- Removing the needle: Careful removal to prevent bruising or bleeding at the site.
- Applying pressure and bandage: Gentle pressure and a sterile bandage application to control bleeding and promote healing.
- Disposing of materials: Proper disposal of used needles and sharps.
- Documenting procedures, results, and any patient observations. Thorough documentation is a vital practice.
Post-Procedure Considerations
- Monitoring the patient: Checking for any signs of complications like bleeding, bruising, or fainting.
- Applying pressure and bandage to the venipuncture site.
- Sending samples to the correct laboratory for testing.
- Labeling tubes correctly with patient identifiers, test requirements, and date/time.
- Advise patient care instructions and guidelines on what to watch for.
- Following up on the patient's condition if necessary to ensure proper recovery.
Potential Complications and Cautions
- Hematoma formation: Bruising at the puncture site due to improper technique.
- Infection.
- Vein damage or inflammation.
- Syncope (fainting): Ensuring patient safety and managing potential emergencies.
- Improper sample handling: Correctly labeling samples to avoid errors.
- Patient reaction: Monitoring patient reaction during and after the draw.
- Improper blood collection technique or inappropriate use of equipment.
Ethical Considerations in Phlebotomy
- Patient confidentiality: Maintaining the privacy of patient information related to their medical records.
- Patient safety: Maintaining a safe and comfortable environment for patients throughout the procedure.
- Adherence to standard guidelines and protocols by phlebotomists.
- Legal regulations and guidelines related to the procedure and patient care.
Specific Considerations
- Children or infants require extra care and considerations. Specialized techniques and equipment are needed for smaller patients, including special needles.
- Patients with a history of blood clotting disorders or higher clotting risk need additional precautions.
- Patients with a history of fainting or discomfort require extra care to ensure their safety.
