[Abstract]:Objective to analyze the etiology of postoperative craniocerebral infection in Department of Neurosurgery, and to analyze the clinical resistance and related factors of pathogenic bacteria, and to provide scientific guidance for the prevention and control of craniocerebral infection after operation in Department of neurosurgery. Methods the clinical data of the patients with craniocerebral infection after the operation were collected and the samples were separated from the specimens of the cerebrospinal fluid. The pathogenic bacteria were identified by the automatic microbial identification instrument and the K-B method was used to analyze the drug resistance of the pathogenic bacteria. Results in 266 Department of neurosurgery patients, 80 cases were infected with intracranial infection, and the infection rate of 30.08%. was isolated from 80 cases of the cerebrospinal fluid samples from the infected patients. Among them, 53 strains of Gram-positive bacteria, 29 Gram-negative bacteria and 2 fungi. Among Gram-positive bacteria, 27 strains of coagulase negative staphylococcus, 12 strains of Staphylococcus aureus, 12 strains of Enterococcus faecalis, 4 other strains, 16 strains of Acinetobacter Bauman, 6 Klebsiella pneumoniae, 3 Escherichia coli, 2 Pseudomonas aeruginosa, 2 strains, coagulase negative Staphylococcus and Staphylococcus aureus to ciprofloxacin, the head of ciprofloxacin, and the head of ciprofloxacin. The resistance rates of sporotazidime, ceftriaxone, chloramphenicol, and vancomycin were 33.33%, 44.44%, 40.74%, 55.56%, 0 and 33.33%, 66.67%, 58.33%, 66.67%, 0; the resistance rates of Enterococcus faecalis to ciprofloxacin, ceftazidime, ceftriaxone, chloramphenicol, moxifloxacin, and gatifloxacin were respectively 30%, 50%, 40%, 60%, and 10.00%. Bauman. The resistance rates of bacteria and Klebsiella pneumoniae to ciprofloxacin, ceftazidime, meropenem, ceftriaxone, chloramphenicol were 37.50%, 50%, 18.75%, 43.75%, 50% and 33.33%, 50%, 0,50.00%, and 60 years old were 17.80%, and 60 years old were 39.86%, and the infection rate of external ventricular drainage was 47.78% and no external ventricular drainage. The infection rate was 21.20%, the infection rate of the cerebrospinal fluid leakage was 45.63%, the non cerebrospinal fluid leakage was 20.25%, the infection rate was 53.27% before operation and 14.47% before the operation, and the difference of infection rate was statistically significant (x 2=15.2040,20.2696,19.3411,45.7982, P 0.05). In the analysis of the original characteristics, the types of pathogenic bacteria are mostly Gram-positive bacteria, and the isolation rate of coagulase negative staphylococcus is the highest, and the spread of this pathogen should be paid great attention to. In view of the degree of drug resistance of the clinical isolates, the antibiotics should be rationally selected in clinical, and the head infection of the patients in the Department of neurosurgery is highly effective. Surgical patients' age, external ventricular drainage, cerebrospinal fluid leakage, and preoperative use of antibiotics are related factors for the occurrence of craniocerebral infection. These factors should be paid attention to, and the analysis of drug resistance to pathogenic bacteria is of great significance for the treatment of patients.
