Abstract
BACKGROUND: Neurosurgeons are vulnerable to additional noise in their natural operating environment. Noise exposure is associated with reduced cognitive function, inability to concentrate, and nervousness. Mediation music provides an opportunity to create a calmer environment which may reduce stress during surgery. METHODS: A pilot study was performed to find a suitable task, meditation music of surgeon's choice, and operation noise and to reach a certain level of training. For the main experiment, two neurosurgeons with different microsurgical experience used real operation noise and meditation music with delta waves as mediating music. Each surgeon performed 10 training bypasses (five with noise and five with music) with 16 stitches in each bypass. The total time to complete 16 stitches, a number of unachieved movements (N.U.Ms), length of thread consumed, and distribution of the stitches were quantified from the recorded videos and compared in both groups. RESULTS: A N.U.Ms were significantly reduced from 109 ± 38 with operation room (OR) noise to 38 ± 13 (p < 0.05) with meditating music in novice surgeon. Similar results were found in the experienced surgeon performing the same task [from 29 ± 6.94 to 14 ± 3.36 (p < 0.05)]. The total time utilized for the sixteen stitches was slightly improved (not significantly) in the novice surgeon and unchanged in the experienced surgeon. However, the thread length used for 16 stitches was significantly different with OR noise in comparison to meditating music in both surgeons. The distribution stitches showed a non-significant trend toward a uniform distribution with meditation music in both surgeons. CONCLUSIONS: Meditation music of surgeon's choice is a simple method that improved quality of bypass suturing in an experimental bypass procedure.
