As interest in the use of ultraviolet rays of certain wavelengths as an agent for killing micro-organisms in the air, particularly in the operating room, has become more widespread, the questions most frequently asked have concerned the results obtained by its use and the possible danger to the patient and to the operating room personnel. Since probably I have had the greatest experience with this recent addition to surgical technic as a routine in all large clean operative procedures, a further report of my experience and results may be of interest and value in this field.
The first operation on a patient in the Duke Hospital in a field of ultraviolet radiation was performed on Jan. 15, 1936. A preliminary report1 based on several years' study of viable bacteria in the air, showing how they can be reduced by air conditioning and almost eliminated by radiation, was made after
