What You'll Learn
Capillary puncture is a critical skill for phlebotomists to master, as it is often used to collect blood samples from infants, young children, or patients with difficult venous access. This method involves using a small, disposable lancet to puncture the skin on the fingertip or heel to obtain a drop of blood for testing. Understanding the proper techniques and safety protocols for capillary puncture is essential for passing the Phlebotomy Certification exam and providing high-quality patient care.
Key Concepts
Capillary Puncture
The process of using a small lancet to puncture the skin on the fingertip or heel to obtain a drop of blood for testing or analysis.
Puncture Site Selection
Identifying the appropriate location on the finger or heel to perform the capillary puncture, taking into account factors like tissue thickness, blood flow, and patient comfort.
Skin Preparation
The steps taken to clean and disinfect the puncture site prior to the procedure, including using an alcohol swab to remove any oils or debris.
Milking Technique
The gentle squeezing or stroking of the finger or heel to facilitate the flow of blood from the puncture site.
Mixing the Sample
Gently inverting or rolling the collection device to ensure the blood is properly mixed with any necessary anticoagulants or reagents.
Common Mistakes to Avoid
- Failing to properly clean and disinfect the puncture site, leading to an increased risk of infection.
- Applying too much pressure when puncturing the skin, causing unnecessary pain and potential tissue damage.
- Improper positioning of the patient's hand or foot, which can make it difficult to obtain a sufficient blood sample.
- Not using the correct milking technique to facilitate blood flow from the puncture site.
- Neglecting to gently mix the blood sample after collection, which can affect the accuracy of test results.
