Abstract: Objective To investigate the effect of operating room environment on stress response during the waiting period in patients with artificial femoral head replacement．Methods Eighty-four patients admitted between January 1,2021 to July 31,2023 required artificial femoral head replacement．According to the operating room environment during treatment,the patients were divided into two groups．Forty-two patients in the control group received the surgical treatment in the original operating room environment and 42 patients received surgical treatment in upgraded environment．Comparing two groups of stress response（adrenaline,cortisol）,emotional status[HAMD score,HAMA score],blood pressure（systolic blood pressure,diastolic blood pressure,heart rate）,quality of life,patient satisfaction with the operating room environment of two groups were compared．Results At time T₁,epinephrine and cortisol levels were significantly increased in the two groups,but the control group increased[（43.48±4.59）pg/L,（268.48±13.55）ng/L] greater than the observation group[（38.15±5.28）pg/L,（240.15±12.48）ng/L],which were statistically significant（t=4.937,9.967,P<0.05）．At time T₁,the HAMD and HAMA scores were significantly higher in both groups,but the increase[（22.84±3.26）and（24.03±3.47）] was greater than the observation group[（19.75±3.73）and（20.76±3.36）],which showed statistical significance（t=4.042,4.387,P<0.05）． At time T₁,SBP,DBP and heart rate increased significantly in both groups,but the control group increased[（129.34±7.25）mmHg,（94.25±6.62）mmHg,（88.58±3.27）][（117.62±8.13）mmHg,（85.63±5.38）mmHg,（82.16±3.66）/min] grater than the observation group（t=6.973,6.549,8.477,P<0.05）．Five days after surgery,the scores of each dimension increased significantly in both groups,but the observation group increased more than the control group（P<0.05）．The observation group patients showed a higher satisfaction rate of the operating room environment than the control group（97.62% vs 85.71%,χ²=3.896,P=0.048）．Conclusion sThe transformation and upgrading of the operating room environment has a positive effect on the patients with artificial femoral head replacement,which can effectively reduce the stress response of patients during the waiting period,reduce the anxiety and depression of patients during the waiting period,and reduce the rise in blood pressure and heart rate of patients during the waiting period,which is conducive to improving the quality of life of patients after surgery and improving the satisfaction of patients with the operating room environment．
