(1) The water-absorbing rate at PIH 24 of Allevyn foam dressing, Mepilex foam dressing, and Biatain foam dressing were respectively (646 ± 18)%, (616 ± 19)%, and (499 ± 11)% (F = 423.854, P < 0.01).
Data were processed with one-way analysis of variance and analysis of variance of repeated measurement, and LSD method was applied in paired comparison. Five samples of each dressing were used for each index. The simulated wound exudation was used to test the water-absorbing rate of dressings at post immersion hour (PIH) 24, water-absorbing speed of dressings at post immersion minute (PIM) 1, 5, 10, and 20, the diffusion diameter of exudation dripped on the surface of dressings for 5 min to reflect the water-locking capacity of dressings, and the water evaporation capacity of exudation after being sealed up by dressings for 24 h to reflect the air permeability of dressings. H2O respectively in the weight of 8.3 g and 0.367 g were diluted with distilled water to the volume of 1 L to simulate wound exudation.The comparison was made among Allevyn foam dressing, Mepilex foam dressing, and Biatain foam dressing that were commonly used in clinic. To compare the properties of water-absorption, water-locking, and air permeability among several foam dressings, and to provide references for clinician in choosing dressings for different types of wounds.
