What are the complications of venipuncture?

Complications of venipuncture can include hematoma formation, where blood collects under the skin, leading to swelling and discoloration. There is also a risk of phlebitis, which is inflammation of the vein, and in rare cases, infection at the puncture site. Additionally, incorrect technique may result in nerve damage or arterial puncture, leading to more serious complications. Overall, while venipuncture is generally safe, awareness of these potential issues is important for medical professionals.
