I have a surgi-ctr practice in an office bldg, with no EP/cath lab etc nearby. My surgeons have been spoiled by us doing most of their PS3 and PS3+ patients without much drama. We cannot do PS4 in an ASC in my state(hence 3+). WHen a pt comes with an AICD and electrocautry is needed, I get a good Hx on why they have the device etc. , I apply the magnet , remove magnet once hemostasis is achieved and call the rep who has been notified, the previous day at least , that we may need them in Pacu to verify defib has been enabled again. There are 4-5 other ASC's in a 30 mi radius of mine. The Medtronic guy barked that they only come to mine. I know the Guidant switch story and am very cautious with the Guidant. The Medtr. guy insisted no interrogation is needed on theirs after magnet placemnt to suspend defib. to verify enabled again. He did admit in the hospitals there are reps floating around daily to interrrogate in the pacu. ...Do you folks do this or would you not do the AICD Pt in an ASC ? MAybe that's why the other ASC's do not call the rep. I see mostly Medtronic> Guidant> St Judes. Couldn't find position statement from ASA regarding this. ....thanks
