The consultants and ASA members strongly agree with the recommendation to select catheter size (i.e., outside diameter) and type based on the clinical situation and skill/experience of the operator. Validation of the concepts addressed by these guidelines and subsequent recommendations proposed was obtained by consensus from multiple sources, including: (1) survey opinion from consultants who were selected based on their knowledge or expertise in central venous access (2) survey opinions from a randomly selected sample of active members of the ASA; (3) testimony from attendees of publicly held open forums for the original guidelines at a national anesthesia meeting; and (4) internet commentary. Evidence was obtained from two principal sources: scientific evidence and opinion-based evidence.
