Abstract

|
|
Purpose: Pressure sore wound develops inevitably in long-term, immobilized and hospitalized patients. Sore wound infection is common problem and makes healing process difficult. We aimed to identify the pathogens of the purulent discharge in sore wound and to obtain information for appropriate antibiotics through a sensitivity test
Methods: The bacteriologic study was made on 120 cases of patients who admitted or visited our hospital from 2004 January to 2005 December for sore wound treatment. Culture material was collected in BBL transport media with cotton swab and cultured by MacConkey agar plate. The method of MIC by VITEK and Microscan was used for sensitivity test.
Results: Among 120 specimens, organisms were isolated from 77(64.2%) cases. Gram positive organisms were cultured in 73 specimens, Gram negative organisms in 46 specemens, and fungi in 2 specimens. Mixed infection by Gram (+) and Gram (-) bacteria were observed in 34 specimens. Among them, S. aureus was the most common isolate in 24(31.2%) patients and 10 (13.0%) S. Aureus isolates were MRSA. The most prevalent Gram-negative organism was Escherichia coli in 20 patients(25.9%). Vancomycin and teicoplanin showed highest sensitivity to Gram-positive organisms and imipenem and amikacin to Gram-negative organisms.
Conclusion: Pressure sore wound demands consideration of multimodal therapeutic aspects and these findings would be useful informations to physicians, nurses and clinical assistants in understanding the nature of sore wound and selecting appropriate antibiotics.
