What are common complications associated with arterial punctures?

Hematoma formation and vessel spasm are indeed common complications associated with arterial punctures.

When an artery is punctured, there is a risk of bleeding underneath the skin resulting in a hematoma, which is a localized collection of blood outside of blood vessels. This can occur if the puncture site does not seal properly, which is a typical concern with arterial punctures due to the high pressure within arterial blood.

Vessel spasm can also happen at the site of the arterial puncture. When a needle is introduced into an artery, the vessel can respond by spasming, which may result in temporary changes in blood flow or pressure. This can lead to discomfort for the patient and may complicate the procedure further, potentially necessitating additional interventions.

Understanding these complications is vital for those who perform arterial punctures to manage risk and ensure the safety and comfort of the patient effectively.
