| Popis: | The control of edema in burn injured patients is a priority as it can impede the wound healing process. Bioimpedance spectroscopy (BIS) has been identified as a method of swelling assessment that has merit after burns. The aim of this study was to examine the reliability and validity of BIS in the measurement of localised burn wound edema across (1) different dressing conditions (no dressing, non silver and silver dressings) and (2) three electrode positions. BIS resistance (R) was hypothesised to be inversely proportional to fluid (edema) volume. BIS was collected in triplicate for all conditions of interest. BIS repeated measures demonstrated excellent concordance for all BIS resistance variables (R 0 , R i , R inf ) (intraclass correlation coefficient = 0.999–1.00, 95% confidence intervals 0.999–1.00) without a systematic difference. Multilevel mixed effects linear regression analysis examined the effect of electrode position and dressing condition on BIS resistance variables. R 0 , R i and R inf significantly increased with decreasing localised limb segment volume (p ≤ 0.01). Resistance was significantly (1) reduced when a silver dressing was in situ (p |
