Accidental Intraarterial Placement of a Venous Cannula: When in Doubt Take it Out!-A Case Report

Pdf Summary

The article discusses a case of accidental intra-arterial placement of a venous cannula in a 3-month-old infant during anesthesia. The importance of careful observation to prevent unintended intra-arterial drug injections is highlighted. It emphasizes the need for vigilance in confirming cannula placement before medication administration, particularly in children with aberrant arterial anatomy. Early identification of arterial puncture indicators is crucial, such as bright red blood backflow and blood gas analysis. The case report details the swift removal of the misplaced cannula, ensuring adequate perfusion and preventing complications. Complications of intra-arterial drug injections, including pain, paresthesia, and limb loss, are discussed, emphasizing the significance of prevention. The article recommends using modalities like blood gas analysis and pressure transduction to avoid inadvertent intra-arterial drug injections. Overall, the study underscores the importance of anatomical knowledge, vigilance, and early intervention to prevent the risks associated with accidental intra-arterial cannulation and injections.
