Malignancy
NO
The aim of the current study is to conduct a randomized controlled trial which assesses types and amounts of noxious chemicals in surgical smoke between patients who use a smoke evacuator and patients who do not.
Efficacy
Comparison of the amount of acetaldehyde between patients who use a smoke evacuator and patients who do not
1.Comparison of the amount of formaldehyde between patients who use a smoke evacuator and patients who do not
2.Comparison of the amount of particles in surgical smoke between patients who use a smoke evacuator and patients who do not

Our randomized controlled trial showed that the use of smoke evacuator removed 70-95% of volatile organic compounds and particulate matters in surgical smoke.
2023 | Year | 11 | Month | 19 | Day |
Twenty years or older patients who underwent laparotomy.
Eligible patients who provided written informed consent were assigned in a 1:1 ratio to either an intervention (use of a smoke evacuator) or a control group.
None
The primary endpoint was a change in the acetaldehyde level in surgical smoke.
