Effects of Noise and Music on Situation Awareness and Mental Workload of Nurse during Operation
Noise exposure is a common operating room (OR) phenomenon.Music has influences feelings, therefore surgical teams usually listen to music when operating.However these noises may impact surgical outcome and patient safety.Nurse staffs are the key factor in patient care in the OR—they bear a significant mental workload and are required to have situation awareness.This study aims to determine the association of sound volume, mood, mental workload and the situation awareness of nurses during operation.We collected 40 surgeries engaged with 40 circulating nurses and 40 anesthesia nurses for sample.The experiment designed 4 between subjects (without music, Chinese songs, FM broadcasting and Mozarts music) and 2 within subjects (55~60dB and 75~80dB), using subjective rating technique to indicate mood, mental workload and situation awareness of participates during operation.SPSS 18.0 for two-way repeated-measure ANOVA, one-way ANOVA and Pearson correlation analysis were used.The result showed that situation awareness of subjects were excellent and stable.The mental workload revealed a statistically significant difference among the specific tasks to be performed especially on time out, and affected by sound volume which caused greater state anxiety of circulating nurses.Mozart music could decrease the mental workload and situation awareness related to achieving positive reaction and to release stress.Mental workload and state anxiety of circulating nurses were positively correlated.As a result of sound volume affecting mental workload and situation anxiety, the music volume should be controlled.The noise produced from equipment and instruments need to be decreased but still maintain the adequate alarm functions.To control the sound volume less than 60 dB is recommended, especially after time out.Mozart effect is notably applied to reduce mental workload and state anxiety.Developing a low volume music environment during an operation will be beneficial to occupational health and patient care outcome.
