Surgical smoke: A hidden killer in the operating room

Area of Science:

• Surgical safety and occupational health.
• Biomedical engineering and aerosol science.

Background:

• Surgical smoke is an aerosol generated by energy-based surgical devices.
• Its composition varies based on tissue type and energy source (e.g., electrocautery, ultrasonic knife).
• Surgical smoke may contain viable cells and pathogens, posing health risks.

Purpose of the Study:

• To review the characteristics of surgical smoke.
• To discuss the current research on protective measures against surgical smoke.
• To highlight the importance of implementing safety protocols in operating rooms.

Main Methods:

• Literature review of studies on surgical smoke composition.
• Analysis of research on the effectiveness of protective measures.
• Synthesis of findings on risks and mitigation strategies.

Main Results:

• Surgical smoke particle size and pathogen content differ by energy device.
• Electrocautery produces smaller particles; ultrasonic knives may carry more viable cells/pathogens.
• Existing protective measures (masks, suction) reduce risk but are underutilized.

Conclusions:

• Surgical smoke presents a significant occupational and patient safety hazard.
• Effective protective measures exist but require consistent implementation by staff.
• Further emphasis on protective strategies is crucial for operating room safety.
