Burn wound biopsy bacterial quantitation: a statistical analysis.
Sequential paired punch biopsy samples were taken from three separate locations on each of four burn patients and were quantitated for the number of viable bacteria per gram of tissue. The range (log10 0.02 to log10 1.51) and the standard deviation (log10 0.67) were determined for each pair. The 95 per cent confidence interval based on any single observation, x, was determined to be x +/- 1.31. It is concluded that the burn wound biopsy is a reliable procedure for quantitating organisms in a burn wound and that changes in sequential samples give an indication of the dynamics of infection in the burn patients.
