RESUMO
OBJECTIVE To approach pathogens and precaution strategy of nosocomial pneumonia in patients with myasthenia gravis.METHODS Forty cases of myasthenia gravis from Jan 2003 to Dec 2006 in a certain hospital were involved in the retrospective review.Patients with myasthenia gravis and nosocomial pneumonia were selected out in accordance with diagnostic criteria of nosocomial pneumonia.Risk factors and pathogens of infection were analyzed.Precaution strategy was formulated.RESULTS There were 26 patients with nosocomial pneumonia among 40 cases of myasthenia gravis.Pathogens isolated from sputum culture were all drug resistant strains.Gram-negative bacteria such as Klebsiella pneumoniae,Pseudomonas aeruginosa,Escherichia coli,etc were the most,accounted for 51.85%(84 strains).The next was Gram-positive bacteria,accounted for 33.33%(54 strains).Fungi ranked the third,accounted for 14.81%(24 strains).CONCLUSIONS Precaution and cure measurement should be adopted to prevent and control the occurrence of nosocomial pneumonia in patients with myasthenia gravis.
