Complications and Troubleshooting

When Things Don’t Go as Planned

Complications can arise during blood collection. Knowing how to react keeps patients safe and reduces stress for everyone.

Common Complications

  • Hematoma (bruising under the skin)
  • Fainting or dizziness
  • Missed veins or multiple attempts
  • Excessive bleeding

Troubleshooting Tips

  • Remove the needle immediately if a patient feels faint.
  • Apply pressure and a bandage to stop bleeding.
  • Try a different site or method if a vein is missed.
  • Always reassure the patient and explain the process.

Real-World Fixes

Quick, calm responses to complications build trust and prevent further issues. Practice and experience make troubleshooting easier over time.

Examples

  • A patient feels lightheaded during a draw, so the phlebotomist lies them down and monitors their recovery.

  • If a hematoma forms, the site is elevated and pressure is applied to reduce bruising.

In a Nutshell

Being prepared for complications and knowing how to respond is vital for patient safety.
