Abstract Objective To explore the application effects of dexmedetomidine nasal administration combined with music therapy in patients before total knee arthroplasty ( TKA) surgery. Methods 50 patients who were received routine intervention before TKA surgery were selected as the routine intervention group, 50 patients who were received music therapy intervention were selected as the music therapy group, and 50 patients who were received nasal administration of dexmedetomidine combined with music therapy were selected as the combined intervention group. The vital signs, anxiety levels, and intervention satisfaction before entering the surgical preparation room ( T0) and before entering the surgical room ( T1 ) were compared among three groups. Results There was no statistically significant difference in T0 heart rate, diastolic blood pressure, systolic blood pressure, and preoperative anxiety scale ( SAQ) scores among the three groups( P>0.05) . The T1 vital sign indicators and SAQ scores were increased to varying degrees, but the T1 vital sign indicators and SAQ scores in the combined intervention group were lower than those in the music therapy group and the conventional intervention group, and the difference was statistically significant ( P<0.05) . The intervention satisfaction rate of 96.00% (48/50) in the combined intervention group was higher than 84. 00% ( 42/50) in the music therapy group and 68. 00% ( 34/50) in the conventional intervention group ( P<0.05) . Conclusion Before TKA surgery, nasal administration of dexmedetomidine combined with music therapy can effectively alleviate anxiety during the waiting period, stabilize vital signs, and improve patient satisfaction with intervention.
