On July 13, 1994, Giddins chaired a meeting of the committee, which was attended by Maas, Odim, McNeill and Youngson. The case of JM (outlined in the previous chapter) was discussed that day. It involved a successful Fontan operation that was carried out on a three-and-a-half year old boy. The key issue in the operation was the anaesthetist's decision to insert a line into the right internal jugular vein. Anaesthetists regarded such lines as being of considerable importance in monitoring their patients. However, in this patient, Odim had had the line relocated because he was worried that such lines could lead to a narrowing of the vein. This was a particular problem in patients undergoing Fontan-type procedures, since the veins might be needed undamaged for future surgery. As a result, the anaesthetists agreed not to place internal jugular lines into patients undergoing Fontan-type procedures. (Exhibit 20, Document 278 E)
