Medical textiles encompass a broad range of products — from sterile surgical gowns and drapes to patient examination gowns, hospital linens, scrubs, and specialty positioning products. While often viewed as a commodity category, medical textile selection has direct implications for infection control, surgical site infection rates, staff comfort, patient dignity, and regulatory compliance. This guide provides a framework for clinical and procurement decision-making across the major medical textile categories.
AAMI PB70: The Standard That Governs Surgical and Isolation Gowns
The ANSI/AAMI PB70 standard establishes liquid barrier performance requirements for protective apparel used in healthcare. Four performance levels define increasing protection against liquids:
- Level 1: Minimal fluid barrier. Suitable for basic care, standard isolation, ICU monitoring. Water resistance ≥20 cm H₂O (AATCC 127 hydrostatic pressure test).
- Level 2: Low fluid exposure risk. Blood draws, phlebotomy labs, pathology. ≥20 cm H₂O by AATCC 127; splash/spray resistance by ASTM F1670.
- Level 3: Moderate to high fluid exposure. Arterial lines, emergency procedures, orthopedic surgery. Critical zones must pass AATCC 127 at ≥50 cm H₂O.
- Level 4: Maximum protection against pathogen-laden fluids. Aerosol-generating procedures, Ebola and hemorrhagic fever management. Must pass ASTM F1670 (synthetic blood) and ASTM F1671 (bacteriophage Phi-X174 virus penetration resistance).
Correct level selection is a Joint Commission and CMS compliance requirement. Facilities must document gown level selection criteria in their infection control and PPE policies.
Surgical Drapes: Sterile Field Maintenance
Surgical drapes create and maintain the sterile field during operative procedures. Key selection considerations:
- Fenestrated vs. universal drapes: Fenestrated drapes have pre-cut openings for specific surgical sites; universal (utility) drapes are used for field expansion and ancillary coverage.
- Impervious backing: Critical zones of surgical drapes must prevent strike-through — fluid penetration from the procedural side through to the patient's skin.
- Adhesive incise drapes: Transparent film drapes (3M Steri-Drape, Ioban) applied directly to surgical site skin. Antimicrobial-impregnated versions (3M Ioban 2) are associated with reduced SSI rates in some literature.
- Disposable vs. reusable: Reusable woven textiles have lower lifecycle environmental impact in high-volume ORs; disposable nonwoven systems offer consistent performance and eliminate laundry logistics.
Patient Gowns: Dignity and Practicality
Patient gowns have evolved significantly from the traditional open-back tie style. Modern considerations:
- Dignity-preserving designs: Rear-closing magnetic, snap, or wraparound designs that maintain coverage during ambulation
- Access for clinical procedures: IV port windows, chest access for cardiac monitoring, catheter drainage accommodation
- Material: Cotton-polyester blends for comfort and durability; antimicrobial-treated fabrics for infection prevention applications
- Pediatric gowns: Child-appropriate patterns and smaller sizing for pediatric wards
Scrubs and Staff Apparel
Clinical scrubs must balance staff comfort, durability, professional appearance, and infection control. Anti-microbial treated scrubs (Vestex, Medline CURAD) show some evidence of pathogen burden reduction, though hand hygiene remains the gold standard intervention. For areas requiring identification by role or unit (OR, ICU, ED), color-coded scrub policies are increasingly common.
Hospital Linens: The High-Volume Textile Category
Hospital linens (bed sheets, pillowcases, towels, washcloths, bath blankets) are among the highest-volume textile items by unit count. Industrial laundry services process hospital linens at temperatures (≥160°F) sufficient to deactivate most healthcare-associated pathogens. Key procurement considerations: thread count (durability vs. softness), shrinkage resistance, and chemical compatibility with commercial laundry detergents and bleach.
