RESUMO
OBJECTIVE:To investigate the current situation of anticoagulant therapy for patients with non-valvular atrial fibril-lation,and to provide reference for standardized anticoagulant therapy. METHODS:A total of 1056 patients with non-valvular atri-al fibrillation were collected from our hospital during Jul. 2015-Jun. 2016. According to 2012 European Society of Cardiology Guide-lines for the Management of Atrial Fibrillation,the risks of thrombosis and hemorrhage were evaluated,and the standardized anti-coagulant therapy was also evaluated. RESULTS:Among 1056 patients with non-valvular atrial fibrillation,the number of patients with thrombosis risk score ≥1 was 1028,accounting for 97.3%. 763 patients received antithrombosis therapy,and only 139 pa-tients were given warfarin anticoagulant therapy. The international normalized ratio(INR)of prothrombin time in just 30.9% of pa-tients receiving warfarin was in line with the standard before discharge. CONCLUSIONS:The anticoagulant therapy for patients with non-valvular atrial fibrillation is still not optimistic,and effective measure should be adopted to improve the standardization of anticoagulant therapy in the patients with atrial fibrillation.
RESUMO
Objective To investigate the risk factors for nosocomial infections and analyze pathogens drug resistance in patients with craniocerebral injury so as to provide scientific basis for clinical precaution and treatment.Methods A retrospective survey was conducted to collect the clinical data of 480 patients with craniocerebral injury including the gender,age and therapeutic process of patients by medical history,for analyzing the related factors causing nosocomial infections via SPSS 18.0 software.Then,the results of bacterial culture and drug sensitivity test were recognized to analyze drug resistance of pathogenic bacteria.Results The nosocomial infections occurred in 100 of 480 patients with craniocerebral injury,with an infection rate of 20.83%.The univariate analysis indicated that the risk of nosocomial infections was associated with age,tracheal tube,deep vein catheterization,the length of tracheotomy,the length of hospital stay,diabetic mellitus and hemoglobin ≤110 g·L-1 (P<0.05).Totally 191 strains of pathogens have been isolated,including 118 (61.8%) strains of gram-negative bacteria,46 (24.1%) strains of gram-positive bacteria and 27 (14.1%) strains of fungi.The Acinetobacter baumannii,Pseudomonas aeruginosa,Klebsiella pneumoniae,Escherichia coli were dominant among the gram-negative bacteria,and the drug resistance rates of them to cefazolin and cefotaxime were high;The Staphylococcus aureus,Enterococcus faecalis and Staphylococcus were the major species of the gram-positive bacteria,which were insensitive to penicillin and clindamycin;the Candida albicans was the major species of the fungi.Conclusion The incidence of nosocomial infections is high in the patients with craniocerebral injury,which is accociated with many risk factors.Therefore,it is necessary to strengthen the control of the risk factors so as to effectively reduce the incidence of nosocomial infections.
