I'm a doctor. Operating rooms have something like 10,000 times the allowed particulate matter compared to a foundry clean room. Additionally in the theatre, there are two surfaces: clean and dirty. Only scrubbed people are clean, and if they touch something dirty they're out. Dirty people can't touch clean things. However the clean people are technically only clean on their arms and between waist and neck. So you will often have (in american theatres j have been in, but never at home in australia) dirty doctors touching clean doctors on the shoulder and having s chat with them. havkng phones in theatre is not going to change the outcome of the procedure or make any material difference to wound healing or infection rates.
