Conditions

Patients in the recovery stage of general anesthesia

Interventions

Noise Reduction Group:Patients wear a 3M X5A noise-canceling headset (37 db noise-canceling signal) immediately after entering the anesthesia resuscitation unit (PACU) until they leave the PACU
Control Group:During the recovery period of anesthesia, patients received routine PACU nursing care without any noise reduction intervention

Design outcomes

Primary

MeasureTime frame
Maximal exercise-induced pain intensity (NRS) within 24 hours after surgery;

Secondary

MeasureTime frame
The 15-item quality of recovery rating scale -Qor-15R-15) was used to evaluate the quality of recovery 24 hours after surgery;The dosages of opioids and other relief analgesics were recorded during and 24 hours after the operation;Resting pain score at 24 hours after surgery;Postoperative sleep quality: Pittsburgh Sleep Quality Index (PSQI) was used to evaluate the postoperative 24h sleep quality.;Correlation between noise exposure measures and postoperative pain: mean noise intensity in the PACU; proportion of time with noise intensity =70 db;Richmond agitation-sedation scale (Rass) was used for evaluation. Pacu stay was assessed every 30 min.;Pacu length of stay and incidence of unplanned events (nausea, vomiting, itching, dizziness, etc.);
