In showbiz, the sequence is lights, camera, action!
On stage, the sequence is music, lights, action!
In the operating room, the sequence is lights, action, camera!
Or more accurately, lights, action, lights, action, focus, shoot. As the scalpel cuts deeper into the layers of the abdominal wall, the lights have to be adjusted, refocused and readjusted every now and then to give the surgeons a good view of what's going on inside the patient. This task of light adjustment often falls on the anesthesiologist as he/she is the one always hovering around the patient and therefore nearest the OR lights. So that's what we actually do in addition to drinking coffee, fiddling with the radio, shooting pictures and basically just sitting around on the job!
Notice the light in the above photo. Is it well focused on the appendix?
See what a big difference a little light adjustment makes on the operative site? This here is one of our favorites: a good morning appendix that pops out of the abdomen right after the incision. :-)
