The Microbiological Investigation of Superficial Colonization on Pressure Ulcers of Patients Managed by Home Care Service

42047

Aim: Taking tissue biopsy is recommended in diagnosis of infected pressure ulcers, however this method cannot be applied in any case. Presuming that the observation of microorganisms colonisation instead of tissue biopsy would be more useful, the microbiological investigation of superficial samples from pressure ulcers of these patients was aimed. Material and Method: The swab samples from pressure ulcers of 68 patients followed by Kocaeli Municipality -Home care service were cultured onto 5% sheep blood and EMB agar. The identification of bacteria and antimicrobial susceptibility tests were determined by VITEK 2 (bioMérieux, Fransa) automatized system. Results: The ratio of grading of pressure ulcers were determined as: 34% grade II, 45% grade III and 21% grad e IV. The swabs were taken mostly from sacrum (58%) and hip (20%) regions. The isolated bacteria were: 48% nonfermentatives, 38% enterics and 14% gram positive bacteria. The most common bacteria isolated were: Pseudomonas aeruginosa (n=23), Proteus spp. (n=20) and Acinetobacter baumannii (n=18). Conclusion: For the diagnosis of pressure ulcer infections, in cases that the gold standard method, deep tissue biopsy cannot be obtained, the evaluation of colonization in superficial samples may be useful in choosing the antibiotics in patients whom treatment is indicated.
