The objective of the present study was to determine risk factors for development of the most common hospital-acquired infections in paediatric burn patients in order to give recommendations for surveillance. The prospective cohort study in a paediatric burn centre was conducted over a period of two years using uni- and multivariate analysis for risk factor identification. In a group of 41 children with an mean total burn surface area (TBSA) of 18.9% 42 hospital-acquired infections were observed. ⋯ Duration of urinary catheter use and ventilation were identified as risk factors for the corresponding hospital-acquired infection. Surveillance of hospital-acquired infections in burn intensive care units should be performed in the same way as other intensive care unit types, as recommended by the National Nosocomial Infections Surveillance system, without consideration of the percentage of TBSA. In addition, burn wound infections should be recorded using the percentage of TBSA for stratification of burn wound infection rates.

This work results from concerns that forced-air convection heaters applied to patients in the operating theatre might interfere with ultra-clean ventilation system and thus be a potential source of wound contamination. Air samples were taken in the operative field and the bacterial load calculated by estimating the number of colony forming units per cubic metre of air (cfu/m(3)). Six tests were carried out, two in empty theatres and four during standard orthopaedic operating lists. ⋯ A further small rise was seen after the convection heaters were turned on when applied to patients. This study showed that use of warm air convection heaters on patients produced a small increase in the number of colony forming units in ultra-clean air theatres but the levels were unlikely to have clinical significance. By far the greatest effect on numbers was movement and presence of the patient and theatre staff in the theatre.
