Let the music play...en pabellón

Un trabajo publicado en JAMA hace 12 años mostró que hay efectos positivos del punto de vista de respuesta fisiológica y velocidad cuando el cirujano escucha música elegida por él o ella. La respuesta era menor cuando no era música seleccionada por el cirujano y aún menor cuando no existía música en pabellón. Trabajos posteriores han mostrado efectos beneficiosos también para pacientes con anestesia regional, y en aquellos con anestesia general al menos hay beneficio durante la inducción y fin de la anestesia.

Effects of music on cardiovascular reactivity among surgeons

OBJECTIVE--To determine the effects of surgeon-selected and experimenter-selected music on performance and autonomic responses of surgeons during a standard laboratory psychological stressor.
DESIGN--Within-subjects laboratory experiment.
SETTING--Hospital psychophysiology laboratory.
PARTICIPANTS--A total of 50 male surgeons aged 31 to 61 years, who reported that they typically listen to music during surgery, volunteered for the study.
MAIN OUTCOME MEASUREMENTS--Cardiac responses, hemodynamic measures, electrodermal autonomic responses, task speed, and accuracy.
RESULTS--Autonomic reactivity for all physiological measures was significantly less in the surgeon-selected music condition than in the experimenter-selected music condition, which in turn was significantly less than in the no-music control condition. Likewise, speed and accuracy of task performance were significantly better in the surgeon-selected music condition than in the experimenter-selected music condition, which was also significantly better than the no-music control condition.
CONCLUSION--Surgeon-selected music was associated with reduced autonomic reactivity and improved performance of a stressful nonsurgical laboratory task in study participants.
