The risk of major complications after vascular access is generally:

The risk of major complications after vascular access is generally considered to be less than 2%. This statistic reflects the overall safety and effectiveness of vascular access procedures, which may include tasks like catheter insertions or peripheral access for interventions.

Major complications can involve issues such as hematomas, infections, arterial punctures, or thrombosis. While the development of advanced techniques, better training, and improved technology has significantly reduced these risks, the figure of less than 2% remains a widely accepted benchmark in clinical practice.

Understanding this percentage is important for practitioners in assessing the risk versus the benefits of performing vascular access, ensuring that patients are informed and that proper protocols are followed to minimize complications effectively. The other figures provided, while reflecting an improvement in complication rates, do not accurately represent the current consensus in the medical community regarding the general risk after vascular access procedures.
