How to lay down sterile treatment drapes

Methods for laying sterile treatment drapes include the single-layer flat method, double-layer flat method, folded drape method, fan-folding method, and fenestrated drape method. Strict adherence to aseptic techniques is required to maintain a sterile environment during diagnosis and treatment. If contamination, damage, or improper handling occurs during draping, it is recommended to promptly replace the drape and seek medical evaluation for potential infection risk.

1. Single-layer flat method: Remove the sterile treatment drape and grasp its two corners with both hands, then lay it smoothly over the treatment area. Ensure the surface is wrinkle-free and fully covers the required area. Once placed, the drape should not be moved arbitrarily.

2. Double-layer flat method: Use two sterile treatment drapes, placing them in overlapping layers. The top drape may be repositioned as needed. The double-layer design enhances sterile protection and is suitable for procedures with higher contamination risks.

3. Folded drape method: Fold the sterile treatment drape twice to create a four-ply fold. Hold the drape by the folded edges and unfold it so that the folded side faces the sterile field. After laying it flat, align the edges precisely with the treatment site—this allows quick placement and reduces the risk of contamination.

4. Fan-folding method: After folding the treatment drape once, continuously fold it from one end to the other into a fan shape. During deployment, hold the non-sterile edges and open the fan toward the operative site. This method is suitable for localized, small-area procedures.

5. Fenestrated drape method: Select a fenestrated drape appropriate for the specific anatomical site. Hold the edges of the drape with both hands and position the opening precisely over the target area, ensuring the surrounding drape adheres tightly to the skin to prevent exposure of the sterile field during the procedure.

After use, promptly dispose of contaminated treatment drapes according to medical waste regulations. Unused sterile treatment drapes must be stored sealed in a cool, dry place to prevent moisture, contamination, or expired use. Regularly inspect packaging integrity and expiration dates.
