Objective To investigate the effects of comprehensive pain management on pains and recovery of knee function of patients who hadundergone total knee arthroplasty(TKA).Methods A total of 50 patients who had undergone single-knee TKA surgery were selected and divided into 2 groups of 25 patients each:the study group and the control group.The control group was given patient-controlled epidural analgesia while the study group was given comprehensive pain management.The two groups were compared in terms of score on pain within 7 days after operation,knee joint activity and the incidence of adverse reaction within 10 days after operation(the 1st,3rd,7th,10th day).Results Within 7 days,the scores on pain in the study were significantly lower than those in the control group(P<0.05).The scores on the knee joint activity in the study group on the 1st,3rd,7th,10th day were significantly higher than those in the control group(P<0.05)and the incidences of adverse reaction were significantly lower as well (P<0.05).Conclusion Comprehensive pain management is effective for post-surgery pain control and the hastened TKA patients, and the improved quality of life.

Objective To explore the effectiveness of using Excel sheets combined with QR codes for precision naviga-tion and location management of sterile instrument rooms in the operating room.Methods The study focused on the location management of nearly 1,000 sterile instruments in three sterile instrument rooms of our hospital.Instruments from July to Septem-ber 2023 were used as the control group,employing traditional location management methods.Instruments from October to De-cember 2023 were used as the observation group,applying Excel sheets and QR codes for precise navigation and location manage-ment.Results The time taken by new nurses and interns to find and retrieve sterile instruments decreased from(4.61±0.32 min)to(1.41±0.15 min).The accuracy of retrieving sterile instruments increased from 83.33％to 98.33％.The compliance rate for location management of sterile instruments improved from 75％to 100％.Nurse satisfaction increased from 81.67％to 96.67％,with significant differences observed(P＜0.05).Conclusion The application of Excel sheets combined with QR codes for precision navigation and location management of sterile instrument rooms in the operating room effectively reduces re-trieval time for sterile instruments,decreases error rates,optimizes management processes,enhances work efficiency,avoids sur-gical delays,ensures patient safety,minimizes conflicts between medical staff and patients,and increases nurse satisfaction.This approach is worthy of clinical promotion and application.
