Objective To explore and analyze the clinical effect of enhanced recovery after surgery to tibial plateau fractures patients applied arthroscopic minimally invasive treatment. Methods A total of 60 tibial plateau fractures patients were selected in our orthopedics department from January 2016 to July 2017 and who applied arthroscopic minimally invasive treatment, according to the last two-digit number of patient ID, divided them into observation group (n=30) and control group (n=30) randomly. The control group used regular perioperative strategies. The observation group used multidisciplinary cooperation fast track surgery idea, through preoperative assessment and education, nutrition and fasting, advance pre-rehabilitation and preventive analgesia; intraoperative optimization of anesthesia, body fluid management and body temperature control; postoperative nutritional support, multimodal analgesia, early ambulation and rehabilitation exercises, implied standardized and professional perioperative overall optimization management. The differences of the condition of 6 h, 12 h, 24 h after surgery, VAS score on discharge, time of first ambulation, active knee flexion 120°days; self-care ability at discharge and AKSS score one month after surgery between 2 groups were compared. Results The VAS scores 6 h, 12 h, 24 h after surgery and at discharge were 4.48 ± 1.18, 3.81 ± 1.68, 3.05 ± 1.63, 2.65 ± 1.65 in the observation group, and were 5.45±1.15, 4.15±1.05, 3.71±1.15, 3.23±1.68 in the control group. The differences were statistically significant (t=0.796~0.902 , P<0.05). The time of first ambulation, active knee flexion 120° days, self-care ability at discharge and AKSS scores one month after surgery were (5.61±1.4) hours, (4.01± 1.1) days, 80.22±3.6, 71.89±6.56 and 64.13±6.15 in the observation group, and (35.8±8.1) hours, (6.82± 1.6) days, 64.25±3.8, 63.45±8.36 and 60.95±8.98 in the control group. The differences were statistically significant (t=2.789~10.200, P<0.05). Conclusion Enhanced recovery after surgery to tibial plateau fractures patients applied arthroscopic minimally invasive treatment is worthy of being popularized as it’s beneficial to tibial plateau fractures patients. It can also fasten recovery and improve quality of life for postoperative patients.

Objective: To investigate the pathogen spectrum distribution and drug resistance of febrile neutropenic patients with hematological diseases in Shanghai. Methods: A retrospective study was conducted on the clinical isolates from the febrile neutropenic patients hospitalized in the departments of hematology in 12 general hospitals in Shanghai from January 2012 to December 2014. The drug susceptibility test was carried out by Kirby-Bauer method. WHONET 5.6 software was used to analyze pathogenic bacteria and drug susceptibility data. Results: A total of 1 260 clinical isolates were collected from the febrile neutropenic patients. Gram-positive bacteria accounted for 33.3% and Gram-negative bacteria accounted for 66.7%. Klebsiella pneumoniae (12.5%) , Stenotrophomonas maltophilia (9.5%) , Escherichia coli (9.1%) , Pseudomonas aeruginosa (8.7%) , Acinetobacter baumannii (6.6%) , Staphylococcus aureus (5.6%) and Enterococcus faecium (5.0%) were ranked in the first 7 of all pathogens. In the respiratory tract secretions specimens, non-fermented strains accounted for 56.2%. Stenotrophomonas maltophilia accounted for 15.2%. Enterobacteriaceae and coagulase-negative Staphylococci accounted for 42.3% (104/246) and 32.6% (85/246) respectively in blood samples. Enterobacteriaceae and Enterococcus bacteria accounted for 39.4% (76/193) and 28.5% (55/193) respectively in pus specimens. The detection rates of methicillin resistant Staphylococcus aureus (MRSA) and methicillin resistant coagulase negative Staphylococci (MRCNS) were 54.3% and 82.5%, respectively. Staphylococcus bacterial strain was not found to be resistant to linezolid, vancomycin and teicoplanin. The detection rate of Enterococcus vancomycin-resistant strains was 8.9%. Enterococcus was not detected resistance to oxazolidinone strains. Enterobacteriaceae bacteria were highly sensitive to carbapenems. The resistance rate of Pseudomonas aeruginosa to imipenem and meropenem was 34.1% and 15.8%, respectively. Stenotrophomonas maltophilia was more sensitive to minocycline hydrochloride, levofloxacin and sulfamethoxazole. The resistance rate of Acinetobacter baumannii only to cefoperazone-sulbactam was less than 10.0%. The antibiotic resistance rate of Klebsiella pneumoniae, Stenotrophomonas maltophilia, Pseudomonas aeruginosa and Acinetobacter baumanii to most of common antibiotics was lower than that of the CHINET surveillance. Conclusions The pathogenic strain distribution in common infection sites of febrile neutropenic patients was characterized. Bacterial resistance surveillance was better than the CHINET nationwide large sample surveillance in China.
