I would be even more concerned about fire & explosion hazard. The cell phone
is most likely not gas-tight. A couple of years ago, I talked with an
anesthesiologist, who related his worries about oxygen and anesthesia gasses
being "trapped" in folds of the patient's blankets (patient heat loss on an
operating table is a concern) or the draping of the procedure site, thereby
creating little "flame or explosion zones".
That surgeon's phone would just about in the worst place relative to the
gasses.
And another thought just arises; how did he take your call? Hard to see how
he could do that without violating the isolation of the operating site. If
this becomes a common practice, we'll soon hear a tale about somebody
"loosing" a cellphone inside a patient, like what happens when they
mis-count the sponges.
