What is a common complication that may occur as a result of improper venipuncture?

A common complication that arises from improper venipuncture is hematoma formation. When the needle penetrates a vein and causes damage to the surrounding tissues, blood can leak out into the subcutaneous tissue, resulting in a localized collection of blood known as a hematoma. This condition can manifest as swelling, discoloration, and tenderness around the puncture site.

Understanding hematoma formation is crucial for phlebotomists, as it highlights the importance of proper technique during venipuncture. Careful needle insertion and withdrawal, along with appropriate site selection and patient positioning, are all vital in reducing the risk of this complication.
