110 A New Antimicrobial Alginate Dressing for Moderate to Heavily Exuding, Infected and Critically Colonised Wounds

Aim: An antimicrobial dressing that combines high absorbency and potent antimicrobial properties. The unique composition of the dressing manages exudates in moderate to heavily exuding, infected or critically colonised wounds, which creates a favourable environment for effective wound management. Methods: Two test methods were used to evaluate the antimicrobial properties of the dressing: 1) A zone of inhibition sensitivity test that challenges the dressing to a seeded agar plate and 2) A log reduction test that exposes a small sample of dressing against a high bacterial loaded broth, measuring the log reduction of the bacteria over a specified time period. The absorbency of the dressing was evaluated using British Pharmacopoeia test methods. Results: The antimicrobial dressing has been shown to be highly effective against a wide range of microorganisms, including Pseudomonas aeruginosa, Escherichia coli, Streptococcus pyogenes, Staphylococcus aureus, Staphylococcus epidermidis, Klebsiella pneumoniae and Candida albicans and also against resistant organisms MRSE, MRSA and VRE. The product is highly absorbent with absorbency > 16 g/g and 16 g/m2.
