Objectives To explore the application effect of orthopedic psychological sleep management mode based on enhanced recovery after surgery (ERAS) in orthopedic patients. Methods A non-synchronous clinical controlled study was conducted. The intervention group enrolled 118 orthopedic patients who admitted to our hospital between April and June 2017, and the control group enrolled 111 orthopedic patients who admitted to our hospital between January and March 2017. The control group used routine nursing measures during hospitalization, while the intervention group implemented an ERAS-based orthopedic psychological sleep management mode based on routine nursing measures, which included carrying out a new mode of multidisciplinary collaborative management, implementing the normative path of orthopedic psychological sleep management, and implementing the comprehensive psychological sleep management. The mood, sleep quality and satisfaction of the two groups within 24 hours after admission and before discharge were compared. Results Before the intervention, there was no statistically significant difference in general data, mood or sleep quality between the two groups (P>0.05). After the intervention, the median score (the lower and upper quartiles) of the Huaxi Emotional Index of the intervention group was 1 (0, 5), while the score of the control group was 2 (0, 6); the median score (the lower and upper quartiles) of the Pittsburgh Sleep Quality Index was 4 (3, 7) in the intervention group and 6 (4, 9) in the control group; the satisfaction score in the intervention group was better than that in the control group (96.47±2.72vs. 95.52±2.79); the differences between the two groups were statistically significant (P<0.05). Conclusions The ERAS-based orthopedic psychological sleep management mode is beneficial to improve the patients’ emotional disorder, sleep quality and satisfaction. It facilitates the patients’ accelerated recovery.
ObjectiveTo investigate the current situation of orthopedic quality control and management in county-level regional general hospitals in Guangdong, and to provide a scientific basis for further standardizing the procedures of orthopedic quality control and management in county-level regional general hospitals and continuously improving the work of provincial orthopedic quality control center.MethodsFrom June 2019 to July 2020, online and offline questionnaire survey and field survey were used to investigate the quality control and management of orthopedic departments in 22 county-level regional general hospitals in Guangdong.ResultsAmong the overall scores of the surveyed hospitals, the highest score was 96.5, the lowest score was 72.0. There were 6 hospitals with a total score of “excellent” (accounting for 27.3%). The “facilities and equipment” and “medical quality” of the surveyed hospitals were relatively valued. Taking Guangzhou, the capital of Guangdong as the center, the districts and counties were divided into the east, the south, the west and the north regions, and the difference in overall scores of orthopedics among the four regions was statistically significant (F=6.299, P=0.004). The unqualified rates of department setting, key technology development, average hospitalization days of representative diseases, equipment allocation, personnel allocation, department management and building layout were relatively high, which were 77.3%, 63.6%, 45.5%, 40.9%, 40.9%, 36.4% and 36.4%, respectively. Most hospitals had set up special debridement rooms in orthopedic department (95.5%), and the management and monitoring of the use of antibacterial drugs was mostly reasonable (90.9%). In terms of the level of orthopedic medical treatment, only 3 hospitals with sufficient key technologies reached the standard, accounting for 13.6%, and only 7 hospitals reached the standard of scientific research capacity, accounting for 31.8%. In terms of quality control, the numbers of hospitals with qualified medical record sampling (72.7%), perfect management and supervision mechanism (86.4%) and quality management team in departments (77.3%) were the least. In addition, among the investigated hospitals, beds were in short supply in orthopedic departments, with 12 hospitals accounting for 54.5% being deducted; 16 hospitals (72.7%) were deducted for unqualified doctor-patient ratio and 11 hospitals (50.0%) were deducted for unqualified nurse-patient ratio.ConclusionsThe overall level of orthopedics construction and management in the surveyed hospitals is uneven. The medical professional and technical level is insufficient. It is difficult to meet the practical needs, and there is an imbalance in the ratio of medical personnel. In the future, it is necessary to strengthen the quality control of orthopedic medical care, strengthen the medical technology training of county-level regional general hospitals and increase the medical and health resources and capital investment, so as to improve the quality control of county-level regional general hospitals.

Objective To explore the application of robot-assisted pedicle screw fixation combined with total endoscopic decompression and interbody fusion in single segment lumbar decompression and fusion. Methods A total of 27 cases undergoing single segment lumbar decompression and fusion between August 2020 and May 2021 in the People’s Hospital of Deyang City were retrospectively collected. They were divided into group A and B according to their surgery method. The patients in group A underwent robot-assisted pedicle screw fixation combined with total endoscopic decompression and interbody fusion surgery, while the ones in group B underwent traditional posterior decompression and fusion. The operation time, amount of bleeding, Visual Analogue Scale (VAS) score and Oswestry Disability Index (ODI) score before operation and one month and three months after operation, and success rate of screw placement were compared. Results There were 12 patients in group A, 5 males and 7 females, aged (59.83±6.79) years, and 15 patients in group B, 6 males and 9 females, aged (53.73±14.87) years. The amount of intraoperative bleeding [(195.00±45.23) vs. (240.00±47.06) mL] and postoperative hospital stay [(5.92±1.56) vs. (8.33±3.62) d] in group A were less than those in group B (P<0.05), while the operation time [(185.80±52.13) vs. (160.70±21.37) min] and the success rate of screw placement [100.0% (48/48) vs. 96.7% (58/60)] had no statistical difference between the two groups (P>0.05). The VAS score and ODI score of the two groups decreased significantly over time (P<0.05), but there was no significant difference in VAS score between the two groups at the same time point before operation, one month after operation, or three months after operation (P>0.05). The ODI score of group A was better than that of group B one month after operation (P=0.010), but there was no significant difference between the two groups before operation or three months after operation (P>0.05). Conclusion Compared with traditional open surgery, the application of robot-assisted total endoscopic lumbar decompression and fusion technology in single segment lumbar fusion has good early clinical outcome, high success rate of screw placement, and small trauma, which is beneficial to early functional recovery and has the significance of further exploring its application prospect.
Objective To investigate the research progress of drug-loaded antibacterial coating of orthopedic metal implants in recent years. Methods The recent literature on the drug-loaded antibacterial coating of orthopedic metal implants were reviewed. The research status, classification, and development trend of drug-loaded antibacterial coating were summarized.
