Real-time Two-dimensional Ultrasound Guidance for Central Venous Cannulation: A Meta-analysis by Wu SY, Ling Q, Cao LH, Wang J, Xu MX, Zeng W.

Summary: Ultrasound-guided techniques have been used to facilitate central venous cannulation (CVC), which may reduce the risk of misplacement and complications. This article discusses a meta-analysis that included 26 studies involving 4,185 CVC procedures. The studies compared anatomical landmark technique use for CVC with real-time two-dimensional ultrasound guidance (RTUS). The data showed that in adult participants RTUS was associated with decreased risks of cannulation failure, arterial puncture, hematoma, and hemothorax.  

Learning Objectives:

The focus of ANESTHESIOLOGY Journal CME is to educate readers on current developments in the science and clinical practice of anesthesiology.

After completing this activity, the learner will be able to:

  • Identify elements of design important for interpretation of clinical study results
  • Identify the serious risks of central venous cannulation (CVC)
  • Select an appropriate ultrasound guidance device for CVC placement
  • Recognize the relative risk for complications of CVC in adults and children when using a real-time two-dimensional ultrasound technique
