[23:03.98]Music to Operate by
[23:07.76]More and more doctors are operating to music
[23:13.31]They say it eases their minds
[23:17.77]One doctor in Chicago says classical music
[23:23.86]is the only kind that does not interfere while he is operating
[23:29.83]But in another Chicago operating room, the British rock group Pink Floyd can be heard
[23:38.40]And in Washington, at least one doctor operates to the sound of the Beatles.
[23:46.07]Researchers from the State University of New York at Buffalo
[23:52.15]did a study that seems to confirm that music helps reduce tension in doctors
[24:00.43]They gave fifty male doctors difficult mathematical kinds of tests.
[24:07.88]The doctors did the test while listening to music they had chosen
[24:14.83]They did a similar test while listening to music that was chosen for them
[24:21.67]They were tested a third time with no music at all
[24:27.36]Each time, a machine measured their heart rate and blood pressure.
[24:34.13]The doctors worked most quickly and calmly
[24:39.53]when listening to the music they had chosen
[24:44.35]They did the worst with no music at all.
[24:49.57]What kinds of music did the doctors choose
[24:54.32]Mostly classical
[24:57.74]But some chose instrumental jazz pieces or Irish folk music.
[25:05.34]There probably is one piece of music
[25:09.69]that should never be played during an operation:
[25:14.88]Brahms' Lullab
