What Are SMS Surgical Gowns?
SMS (Spunbond-Meltblown-Spunbond) surgical gowns are three-layer nonwoven fabric garments designed to provide fluid barrier protection during surgical procedures. The unique tri-layer construction combines the strength of spunbond polypropylene with the filtration properties of meltblown material.
AAMI Protection Levels
| AAMI Level | Protection | Typical Use |
|---|---|---|
| Level 1 | Minimal risk | Basic care, standard medical unit visits |
| Level 2 | Low risk | Blood draws, suturing, pathology |
| Level 3 | Moderate risk | Arterial blood draw, IV insertion |
| Level 4 | High risk | Long surgery, high fluid exposure |
Material Specifications
Standard SMS surgical gowns typically range from 35-45 GSM (grams per square meter). The three-layer construction provides an optimal balance of breathability, comfort, and fluid resistance.
Procurement Best Practices
When sourcing SMS surgical gowns, verify AAMI level testing documentation, request sample sizes for fit evaluation, and confirm sterile packaging integrity. Negotiate annual contracts to lock in pricing and ensure supply continuity.
