Antithrombin use during pediatric cardiac extracorporeal membrane oxygenation admission: insights from a national database.

Recently, antithrombin usage has been decreasing-potentially due to the reported lack of clinical benefit. Together, these results reinforce that antithrombin may not be indicated for all pediatric extracorporeal membrane oxygenation patients.
