Why do medical doctors wear blue colored uniform during the operations?
- Dec 25, 2017 -

Surgical caps face masks, and surgical wear colored blue or green is fairly standard. 

But it wasn't always this way. In the past, disposable medical clothing and apparel was colored white. Why the change?

Scrubs, the common name for disposable medical clothing, were once only worn during surgery.  Only a few decades ago, often only nurses wore bright, white uniforms in hospitals, doctors would simply wear the well-known white coat over their clothes. However, white is almost never used in the operating room today. Scrubs are worn not just in surgery, but throughout the day in hospitals and clinics by both nurses and doctors. Disposable medical clothing is worn primarily for cleanliness. Germs cause infection and disease, and the ability to discard contaminated clothing is important, as well as the ability to easily see possible contaminants.

Medical clothing was white because it allowed easy recognition of anything that wasn't supposed to be there-- dirt, blood, etc. It had to be washed or thrown away, so the white easily showed whether an item was clean or dirty. Many items were being thrown out because the white was hard to clean and doctors found the white on white coloring in the operating room caused severe eyestrain. The psychological effect of bright red blood on white clothing and sheets was also taken into account. They found light blues and light greens maintained the high contrast of a white background, but softened it slightly, causing less eyestrain for surgeons and doctors involved in complicated surgeries. The appearance of red blood on green or blue backgrounds tended to be less gory. Along with the development of disposable fabrics, the present day disposable lab coat became standard for procedures, surgeries, and sometimes even regular exams.
