What is the purpose of aluminum-coated drapes?

• A. They deflect laser energy and prevent ignition in an oxygen-rich environment, especially in head and neck surgery.
• B. They provide cosmetic appearance.
• C. They immobilize the patient.
• D. They absorb laser energy to slow the procedure.

Answer: (A)

Aluminum-coated drapes are used for laser safety in the operating room. The aluminum layer reflects and deflects laser energy away from the drape and patient, reducing heat buildup and lowering the risk of ignition in oxygen-rich environments, which is especially important in head and neck procedures. This reflective, flame-resistant barrier helps prevent drape ignition if stray laser energy contacts it. It’s not intended for cosmetic reasons, immobilization, or to absorb energy to slow the procedure.
