BACKGROUND Neurologic complications are common, and amongst the most devastating complications in pediatric patients undergoing extracorporeal life support (ECLS). Carotid artery cannulation (CAN) has been associated with an increase in these complications, thereby shaping practices to avoid this approach in most pediatric patients in which other cannulation approaches are viable. METHODS A retrospective review of children (0-18years) in the ELSO database was undertaken from 1989 through 2013. Multivariate logistic regression analysis of rates of stroke and other neurologic complications based on cannulation technique was undertaken, adjusting for patient factors including age, underlying disease process, and severity of illness. RESULTS A total of 30,282 ECLS runs were found in the database. CAN was associated with higher rates of stroke (5.15% vs 3.74%) and overall neurologic complications. However, when correcting for patient factors, including age, underlying disease process, and support type, CAN was not associated with an increased rate of neurologic complications or stroke (p>0.05 for both). CONCLUSION When correcting for patient related factors CAN is not associated with an increase in stroke or neurologic compilcations. CAN should be re-examined as a cannulation technique for older pediatric patients. LEVEL OF EVIDENCE III.
