Ethicon has announced its continued support of guidelines from the Society for American Gastrointestinal and Endoscopic Surgeons (SAGES), which recommends the use of personal protective equipment (PPE) and smoke evacuation in the operating room during laparoscopic and open surgery.
Currently, there is no data on the transmission of SARS-COV-2 in surgical smoke during surgery, however, there is no indication or proof that SARS-COV-2 is not transmissible through surgical smoke1. In fact, there is no conclusive evidence to indicate that use of electrosurgical or ultrasonic devices during surgery increases the risk of infectious disease transmission via surgical smoke2. SAGES and AORN are providing recommendations to ensure the perioperative team takes measures to protect themselves from any potential unknown risk1,3. Ethicon recommends the use of smoke evacuation to minimise the potential risk to surgical teams from potentially hazardous substances including cellular material, blood fragments, bacteria, viruses, toxic gases, vapours and chemical compounds4.
“We stand with the surgical and healthcare community during this unprecedented and challenging time,” said Dr Raymond Fryrear, VP & Integrated Leader, PreClinical, Clinical and Medical Affairs, Johnson & Johnson. “The safety and protection of hospital personnel and patients has always been our top priority. Our goal is that every hospital has access to smoke evacuation and energy products in an effort to make procedures safer for surgeons, nurses and the entire OR team.”
In early April, Ethicon released a letter to customers explaining its support of the SAGES surgical guidelines and describing the theoretical risk of COVID-19 transmission through surgical smoke. The company noted that COVID-19 particles range from 60-140 nanometers (nm) in diameter and generally disperse in the form of much larger water droplets. Smoke evacuators that use an ULPA filter (such as Ethicon’s Megadyne Smoke Evacuators), capture and filter at least 99.999954% of particulates and microorganisms sized 120nm. ULPA filter efficiency improves with particles both smaller and larger than the listed size rating (rating range of 100-200nm)5.
