PREDOMINANCE OF STAPHYLOCOCCAL ORGANISMS IN INFECTIONS OCCURRING IN A BURNS INTENSIVE-CARE UNIT

To assess the sites, incidence, and bacteriology of infections burn patients, a prospective survey of all admissions to a tertiary care institution burn unit was carried out over a 12-month period, One hundred and sixteen patients were admitted, 106 with a diagnosis of thermal bums. Forty patients developed 90 infections. Only two deaths occurred, one in a patient with sepsis. In order of frequency, pneumonia, burn infection, UTI and primary bacteraemia were most common. Staphylococcal species accounted for a majority of infections at all body sites except UTI (4 7 per cent of all infections, including 11 of 14 bacteraemic infections). Staph. aureus sepsis was more common in those carrying the organism on admission. Strain typing of paired admission and subsequent clinical isolates in 19 patients with Staph. aureus sepsis indicated that eight (42 per cent) became infected with a strain they carried on admission, Further reductions in septic complications of burns in our center would be best directed at staphylococcal species, particularly Staph. aureus. Both eradication of carrier state, and prevention of acquisition of Staph. aureus strains could be explored.
