ObjectiveTo analyze the risk factors of acute wound infection in orthopedic patients. MethodsA retrospective analysis was made on the clinical data of 576 orthopedic patients in accordance with the inclusion criteria between July and October 2012. There were 345 males and 231 females, aged 18-95 years (mean, 44 years). Single factor analysis was used for related factors, and logistic regression analysis of multi-factors for risk factors of acute wound infection. ResultsWound infection occurred in 73 of 576 patients (12.7%). Single factor analysis showed that the influence factors were gender, education, smoking history, nutritional status (hemoglobin, red blood cell count, serum albumin, and total serum protein), blood glucose level, shock history, wound situation (characteristics, multiple injuries, and cleaning), type of injuries, the time of trauma handling, antibiotic use, whether to stay in ICU, wound pain score, drug analgesia, patient controlled analgesia, and dressings and cleaning solution choice. The logistic regression analysis showed that the gender, time of trauma handling, blood glucose level, wound pain score, dressing choice, and wound characteristics were the risk factors of acute wound infection (P<0.05). ConclusionTo achieve the best results in clinical prevention of infection, these risk factors (gender, the time of trauma handling, blood glucose level, wound pain score, dressing choice, and wound characteristics) should be considered well.
ObjectiveTo analyze the clinical characteristics, risk factors, and drug resistance of pathogenic bacteria in patients with blood stream infections (BSI) after orthopedic surgery, so as to provide reference and basis for clinical diagnosis and treatment.MethodsA retrospective analysis was made on the clinical data of 6 348 orthopedic patients admitted for surgery between January 2017 and December 2019. There were 3 598 males and 2 750 females. Their age ranged from 18 to 98 years, with an average of 66 years. The data of patients were collected, and the risk factors of BSI were analyzed by univariate analysis and logistic regression analysis. The distribution of BSI pathogenic bacteria, the results of drug sensitivity test, the incidence of BSI in patients after orthopedic surgery in different years, and the common sites of BSI secondary infection were summarized.ResultsBSI occurred in 106 (1.67%) of 6 348 patients after orthopedic surgery. There were 71 cases (66.98%) of secondary infection. The mortality of postoperative BSI patients was 1.89%, and the difference was significant when compared with that of non-postoperative BSI patients (0.24%) (χ2=5.313, P=0.021). The incidences of BSI in 2017, 2018, and 2019 were 1.18%, 1.53%, and 2.17%, respectively, showing an increasing trend year by year (trend χ2=6.610, P=0.037). Statistical analysis showed that the independent risk factors for BSI after orthopedic surgery (P<0.05) included the trauma, length of hospital stay≥14 days, emergency surgery, postoperative leukocyte counting<4×109/L, level of hemoglobin≤90 g/L, albumin≤30 g/L, the time of indwelling ureter>24 hours, use of deep vein catheter insertion, and merging other site infection. Blood culture showed 56 strains (52.83%) of Gram-positive bacteria, 47 strains (44.34%) of Gram-negative bacteria, and 3 strains (2.83%) of fungi. The top three pathogenic bacteria were coagulase negative Staphylococci (CNS; 36 strains, 33.96%), Escherichia coli (16 strains, 15.09%), and Staphylococcus aureus (15 strains, 14.15%). The detection rates of extended-spectum β-lactamases producing strains of Escherichia coli and Klebsiella pneumoniae were 56.25% (9/16) and 44.44% (4/9), respectively. The detection rates of methicillin-resistant strains in Staphylococcus aureus and CNS were 46.67% (7/15) and 72.22% (26/36), respectively.ConclusionPostoperative BSI in orthopedic patients is caused by multiple factors. Preventive measures should be taken according to related risk factors and perioperative risk assessment should be strengthened. Staphylococcus and Escherichia coli are the most common pathogenic bacteria in BSI after orthopedic surgery. The infection rate and drug-resistant bacteria are increasing year by year. Therefore, drug resistance monitoring should be strengthened.
ObjectiveTo summarize the research and application progress of magnesium and magnesium alloys implants in the orthopedics. MethodsThe domestic and foreign related literature about the research progress and application of magnesium and magnesium alloys implants in the orthopedics was reviewed. ResultsCurrently approved and commonly used metallic implants in orthopedics include stainless steels, titanium alloys, and chromium alloys having many disadvantages of poor biocompatibility, mismatch with the biomechanical properties of the bone tissue, and need of second surgical procedure to remove. Compared with traditional implants, magnesium and magnesium alloys have biomechanical properties closer to natural bone tissue, and in vivo degradation, which have the potential to serve as new biocompatible and degradable implants. Although magnesium and magnesium alloy materials have their own advantages, but the degradation rate is still too fast and so on. At present, the research and development of medical magnesium and magnesium alloy materials are to improve their corrosion resistance and control the rate of degradation. ConclusionMagnesium and magnesium alloys have great potential as a implant material in the orthopedics, through further systematic and in-depth study, it is expected to become a new generation of degradation biological implant materials.
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.

The disease spectrum included 12 categories. b) A total of 1 093 inpatients suffered from the top 3 systematic diseases as follows: trauma and toxicosis, musculoskeletal system and connective tissue disorders, and the factors affecting health and resulting from contact with health care institutions. Except the musculoskeletal system and connective tissue disorders, the other 2 systematic diseases were mostly seen in male rather than in female. c) According to ICD-10, the top 9 diseases of trauma and toxicosis were injuries to the wrist and hand, injuries to the hip and thigh, injuries to the knee and lower leg, injuries to the shoulder and upper arm, injuries to the lower back, lumbar spine and pelvis, injuries to the elbow and forearm, injuries to the thorax, injuries to the neck and injuries to the ankle and foot; the top 4 diseases in musculoskeletal system and connective tissue disorders were dorsopathies, soft tissue disorders, arthrosis, and osteopathies and chondropathies; among the factors affecting health and resulting from contact with health care institutions, removal of fracture fixation device. d) According to ICD-10 (list of three-digit catalogue and four-digit sub-catalogue), the top 5 single diseases in trauma and toxicosis were muscle and tendon injuries of the wrist and hand, intertrochanteric frature, fracture of the femoral neck, fracture of the tibia and fibula, and fracture of the lumbar spine; the top 5 single diseases in musculoskeletal system and connective tissue disorders were lumbar disc herniation, spondylosis, arthrosis of the knee, osteoporosis with pathological fracture, and osteonecrosis. e) The average hospital stay were 23.55 days, and the average cost per capita were 13 073.73 yuan which were constituted by material cost, drug cost including western and Chinese medicines, treatment expenses including blood transfusion fee, operation expenses including anesthetic fee, examination expenses including radiation fee and laboratory fee, bed fee and others. The inpatient costs were mainly at patient’s own expense, nearly a half of those expenses were paid by social security, and public medical care only accounted for less than 3% of the total payment. Conclusion In 2009: a) The male inpatients were mainly the young and middle-aged, and the female were the elderly. The main 3 systematic diseases were trauma and toxicosis, musculoskeletal system and connective tissue disorders, and the factors affecting health and resulting from contact with health care institutions. Except the musculoskeletal system and connective tissue disorders, the other 2 systematic diseases were mostly seen in male rather than in female. b) The top 3 single diseases were lumbar disc herniation, muscle and tendon injuries of the wrist and hand, and intertrochanteric fracture. Except lumbar disc herniation, the other 2 single diseases were mostly seen in male rather than in female. c) The average hospital stay was 23.55 days. The overall costs were mainly constituted by material and drug cost (59.25%), with rationality worthy of attention. d) Inpatient costs were mainly at patient’s own expense or paid by social security, and the proportion of public medical care was low in the payment.
Enhanced recovery after surgery (ERAS) has been carried out in many surgical fields such as orthopedics, galactophore, cardiothoracic surgery, gastrointestinal surgery, and obstetrics due to its standardized perioperative management process to reduce surgical stress and reduce surgical complications. After more than a decade of development, ERAS has achieved initial results. However, in China, the development of ERAS in orthopedic is still in its infancy. Most of the researches focus on the multidisciplinary management path of perioperative period. How to break through the existing bottlenecks is the key to accelerate the further development of rehabilitation. Therefore, this paper introduces the origin and development of ERAS, analyzes the challenges and opportunities of orthopedic ERAS in clinical advancement, proposes the important measures to promote the accelerated development of orthopedics, and provides new ideas for promoting the in-depth development of orthopedics accelerated rehabilitation.
