Ultrasound-guided vascular access in critical illness.

Area of Science:

• Medical Imaging
• Critical Care Medicine
• Vascular Surgery

Background:

• Ultrasound (US) has become integral to vascular device insertion in critically ill patients over the last 20 years.
• Its application extends beyond central venous catheters to peripheral vessels, arteries, and extracorporeal life support access.

Purpose of the Study:

• To review the current state of ultrasound-guided vascular access.
• To emphasize the importance of a systematic, protocolized approach for safety and efficacy.
• To discuss future directions in the field.

Main Methods:

• Review of current literature and clinical practices in ultrasound-guided vascular access.
• Emphasis on central venous catheter insertion, with broader discussion of other vascular access sites.
• Recommendation for a standardized, protocolized approach.

Main Results:

• Ultrasound guidance significantly improves safety and accuracy in vascular device insertion.
• A systematic approach standardizes practice, aids training, and facilitates quality improvement.
• Current practices and future trends in US-guided vascular access are addressed.

Conclusions:

• Ultrasound-guided vascular access is a well-established technique for critically ill patients.
• Implementing a systematic protocol is recommended to optimize procedural outcomes.
• Continued advancements are expected in US-guided vascular access techniques and applications.
