'Improving OR Safety During Laparoscopic and Open Surgery and the Role of Smoke Evacuation

Ethicon’s new report looks at how to enhance operating room safety, the impact of COVID-19 on our current environment, the smoke evacuation solutions available in the market and the latest guidance for nurses, surgeons and hospital administrators on reducing the impact of surgical smoke.

Potential dangers of surgical smoke

What is surgical smoke?

Surgical smoke is formed when energy-generating devices raise the intracellular temperature of tissue causing tissue vaporization. Smoke can be described as surgical plume, aerosol and vapor.3,5

How can we create a safer OR?

Smoke evacuation is the ability to capture the smoke generated at the surgical site and route it to an area away from the surgical team where it can be filtered. 6

“Plume/smoke evacuation systems should always be used during the procedure with heat producing instruments or devices.”

Why could surgical smoke be hazardous for health?

Approximately 150 chemical constituents have been found in surgical smoke, including carbon monoxide, hydrogen cyanide, acrylonitrile, formaldehyde and benzene.8,9 As well as viable bacteria and infectious viruses such as HIV, hepatitis B and HPV.8,9

The effects of surgical smoke

Potential Short- and Long-Term Health Risks

CDC*: “Exposure to surgical smoke can cause both acute and chronic health effects ranging from eye, nose and throat irritation to emphysema, asthma or chronic bronchitis.10≠

Operating theater nurses may have an increased prevalence of respiratory illnesses (sometimes twofold) compared to the general population.11*

Surgical smoke plumes may cause both acute (e.g., sore eyes, dermatitis) or chronic (e.g., asthma) health effects.4

We are committed to improving safety in the operating room

Smoke might be hazardous for the health of operating room personnel. Blended current electrosurgery can contain viable bacteria. Viral DNA has been discovered in surgical smoke and may lead to disease transmission.13 Every OR deserves to be smoke-free OR.
