Abstract:

Objective

To analyze the pathogenic bacteria characteristics and risk factors for nosocomial infection of patients in Neurology & Neurosurgery in Hospital of the Chinese People’s Armed Police Force, and to investigate the prevention and cure measures for nosocomial infection.

Methods

The clinical data of pathogenic bacteria characteristics and the risk factors of iatrogenic infection of neurosurgery inpatients in our hospital from 2012 to 2014 were reviewed, retrospectively.

Results

Among the 450 strains of pathogens isolated, Gram-negative bacteria were predominant pathogens, accounting for 90.89% (409/450), Gram-positive cocci accounted for 7.11% (32/450), and fungi accounted for 2.00% (9/450), the 4 species of pathogens most widely distributed were Klebsiella pneumonia (30.00%, 135/450), P. aeruginosa (27.11%, 122/450), Acinetobacter baumannii (14.22%, 64/450) and E. coli (9.11%, 41/450). Gram-positive cocci was resistant to ceftriaxone, compound sulfamethoxazole, aztreonam, etc. Underlying diseases, invasive treatments, long-term and broad-spectrum antibiotic therapy, mechanical ventilation, low albumin maybe the risk factors of the prognosis of patients with nosocomial infection.

Conclusions

Multi-drug resistant Gram-negative bacteria showed a trend of fashion in neurosurgery of our hospital. Underlying diseases, invasive treatments, long-term and broad-spectrum antibiotic therapy, mechanical ventilation and low albumin were closely related with the prognosis of patients with nosocomial infection.

Key words: Neurosurgery, Nosocomial infection, Pathogenic bacteria, Multi-drug resistance
