CHICAGO — For fellows in pulmonary and critical care medicine, training with a video laryngoscope, rather than a direct scope, improves first-pass success and decreases the complications of urgent endotracheal intubation, a new study has found.
"I think everybody should be using the video laryngoscope, at least nonanesthesiologists," said Michael Silverberg, MD, from Beth Israel Medical Center, in New York City.
Although research has shown that video laryngoscopy improves glottic visualization during elective surgery in the operating room, direct laryngoscopy is routinely used to perform uncomplicated endotracheal intubation outside the operating room.
This study was designed to test the effectiveness of video laryngoscopy outside the operating room.
Dr. Silverberg presented the research here at CHEST 2013, where he is a semifinalist for the Young Investigator Award.
The researchers compared video with direct laryngoscopy in a prospective randomized controlled trial conducted at an 856-bed medical center with a closed 16-bed medical intensive care unit.
The 153 study participants "were fairly sick," Dr. Silverberg noted. Patients undergoing elective intubation, those with a known history of difficult intubation, and those who had a limited mouth opening were excluded.
The first-pass success rate for fellows in pulmonary and critical care medicine was significantly better with the video laryngoscope than with the direct laryngoscope. After 2 attempts with the direct laryngoscope, fellows were instructed to switch to the video laryngoscope.
