-XT- CLOSED CIRCUIT COLOR TELEVISION IN SURGERY A Report Prepared by- Burton Paulu University of Minnesota--Minneapolis The News-Letter editor recently spent two very.interesting days at the University of '“Kansas as guest of Ed Browne, director of Radio and Television at that NAEB member institution. High point of the visit was the half day spent in the University of Kansas medical center in Kansas City where, with Dr. Paul Shafer, Dean of the Univer¬ sity of Kansas medical school as guide, he inspected the closed circuit color tele¬ vision installation in their hospital. What follows is strictly a layman's account of what he saw. Facilities Described The heart of the installation is the one camera mounted directly above the operating table in one of the medical center's operating rooms and the small adjacent control room. For viewing there is one receiver in a classroom seating twenty students, to¬ gether with three other receivers which can be placed in either of two small audi¬ toriums for larger groups. The accompanying sound system makes it possible for the operating surgeon, the control operator and the viewing groups to communicate with each other while operations are in progress. Before long another television set and two-way sound system will be set up in the office section of the surgery department permitting easy and quick conferences between the operating surgeon and other members of the hospital staff. The television engineer can adjust the camera's position and focus from the control room, and can also select which of the two lenses is to be used. (The camera, how¬ ever, is sufficiently above the table so as to be out of the surgeon's way at all • times.) The lighting used for the operation is sufficient for good television re¬ production. CBS Color Used The viewing screen very satisfactorily reproduces the operation in progress. In fact, a comparison of the view of the operating table through the control room win¬ dow with the picture on the screen leaves no doubt of the great superiority of the television picture over .such direct-viewing as can be done from the cat-walk- orig¬ inally provided for medical students when the hospital was first built. The CBS color used is very satisfactory. Dr. Shafer reports, although the monochrome system originally tried gave inadequate definition. To this editor’s unpracticed eye the two operations observed were reproduced with excellent fidelity. On the only previous occasion he had been in a hospital operat¬ ing room when an operation was in progress, the editor himself was the patient—end very much asleep; so all this proved a new and fascinating experience. The teaching possibilities of such an arrangement are clear: in addition to seeing so clearly, one can hear the surgeon comment on the operation as it proceeds; the doctor can talk to the listening students as he works, pointing out the problem of the mdmerit and explaining how to deal with it; and the students can view the operation alohg with a staff member who can make additional Comments. The operating surgeon can also solicit advice from other members of the staff if he so desires.
