Abstract: Objective To investigate the current status of noise annoyance,emotional labor and burnout among operating room nurses,explore the relationship between noise annoyance,emotional labor and burnout among them. Methods The nurses in the operating room of 11 tertiary hospitals in Guizhou Province were investigated through the general information questionnaire,the noise annoyance scale,the emotional labor scale and the job burnout scale from March to July 2023,and the data were analyzed by constructing a structural equation model. Results The average score[M（P₂₅,P₇₅）] of the noise annoyance measurement scale among 827 operating room nurses was 2.80（2.00,3.00）points,the score of average score of the emotional labor scale items was 3.50（3.00,4.00）points,and the total score of job burnout was 67.00（60.00,76.00）points. The Cronbach's α coefficient of each dimension of the scale was >0.789,the combined reliability value was >0.78,the average variance extraction value was >0.5,and the square root of the average variance extraction value was greater than the correlation coefficient between the variable and other latent variables,and the model fit was excellent. The noise annoyance had a direct positive impact on emotional exhaustion,depersonalization,surface behavior,and natural emotional expression（β=0.339,0.198,0.463,0.300,all P<0.01）,and a direct negative impact on deep behavior（β=-0.117,P<0.01）. The surface behavior directly and positively affected emotional exhaustion and depersonalization（β=0.437,0.466,both P<0.01）,and directly and negatively affected personal sense of achievement（β=-0.134,P<0.05）. The deep behavior had a direct negative impact on depersonalization and a direct positive impact on personal achievement（β=-0.296,0.390,both P<0.01）.The emotional labor of operating room nurses played a mediating role between noise annoyance and occupational burnout. The direct predictive effect of noise annoyance on emotional exhaustion accounted for 62.20% of the total effect,while the indirect effect accounted for 37.80% of the total effect. The direct effect on depersonalization accounted for 42.86%,while the indirect effect accounted for 57.14%. Conclusion The nursing managers can improve the occurrence of negative emotional labor strategies and burnout by reducing noise annoyance,which provides references for hospital managers from a new perspective to stabilize the nursing team in the operating room of the hospital and improve the quality of care.
