[Dubious effect of surgical masks during surgery]

Area of Science:

• Infection Control
• Surgical Safety
• Evidence-Based Medicine

Context:

• The use of surgical masks is a standard practice in operating rooms worldwide.
• Concerns remain regarding the actual impact of surgical masks on preventing post-operative infections.

Purpose:

• To review and analyze existing scientific literature on the efficacy of surgical masks in reducing post-operative infections.

Summary:

• A PubMed search identified four relevant studies involving 6,006 patients comparing surgical mask use versus no mask use.
• None of the reviewed studies found a statistically significant difference in post-operative infection rates between the groups.
• The limited number of studies and patients restricts definitive conclusions about mask efficacy.

Impact:

• Current evidence does not strongly support or refute the routine use of surgical masks to prevent post-operative infections.
• Highlights the need for larger, high-quality studies to clarify the role of surgical masks in infection control.
• Informs surgical practice and policy development regarding personal protective equipment in the operating room.
