Gauze, cotton, and swabs are essential sterile wound care supplies made primarily from 100% cotton or non-woven fabrics, prized for superior absorbency (up to 10x their weight in fluids), breathability, and low-linting properties that minimize infection risk. Gauze swabs/pads (4x4, 2x2; 8-12 ply) clean wounds, apply ointments/antiseptics, debride debris, pack cavities, or serve as primary/secondary dressings; sterile versions (EtO gamma-irradiated) prevent bacterial ingress during surgical site prep or post-op care. Cotton balls/rolls offer gentle padding for sensitive areas, while non-woven swabs reduce fraying for precise procedures like dental packing or minor lacerations.
