3. Procedures for Disinfection. 



Space will not permit entering into a full discussion, nor is this necessary 

 as it may be presumed that the pharmacist will know how to meet the special 

 conditions which may arise, should he be called upon to do so. 



A. Surgical Disinfection. — a. The operating room must be cle^n and free 

 from pathogenic and other objectionable organisms. The room must there- 

 fore be disinfected from time to time, after the method of procedure for any 

 room which may be assumed to be infected, as will be explained under room 

 and house disinfection. As to when, how often or how completely the operat- 

 ing room is to be disinfected that must be left to the judgment of the surgeon 

 in charge. 



b. Surgeons should be especially careful regarding personal cleanliness, 

 irrespective of the routine personal disinfection and sterilization performed 

 preparatory to an operation. They should always be smooth-shaven as the 

 beard is a carrier of germs. 



c. On preparing for an operation the surgeon removes coat, cuffs and 

 collar in an ante-room ; rolls up shirt sleeves and proceeds to wash and scrub 

 hands with tincture of green soap, then in 1-1.5 P^r cent, tinct. cres. comp. 

 U. S. P. or lysol, rinse in sterile water, dry with a clean sterile towel and dip
