In this episode of the Society of Critical Care Medicine (SCCM) Podcast, host Kyle B. Enfield, MD, FCCM, speaks with Garrett McDougall, MS, MSc, and Ben Forestell, MD, of McMaster University about their recent study, “Direct Laryngoscopy Versus Video Laryngoscopy for Intubation in Critically Ill Patients: A Systematic Review, Meta-Analysis, and Trial Sequential Analysis of Randomized Trials,” published in the November 2024 issue of Critical Care Medicine. The study included 20 randomized controlled trials encompassing 4569 patients to investigate whether video laryngoscopy (VL) offers advantages over direct laryngoscopy (DL) for intubation in critically ill patients.
A key finding of the study was that VL probably improves first-pass success rates and reduces the risk of esophageal intubation and dental injury. These benefits extend across the spectrum of operator experience, especially among novice operators but also among seasoned operators.
Drs. McDougall and Forestell discuss findings that surprised them, such as seeing equal benefit for standard VL and hyperangulated VL devices. Additionally, no clear benefits were found for patients who were intubated emergently with VL as compared to those who underwent elective intubation.
The discussion covers what could be next for resuscitation and airway research in critically ill patients. There may be more to learn about scenarios involving difficult airways, soiled airways, and emergent versus elective intubation. More research on device characteristics could also provide important insights.
To wrap up, the guests underscore the importance of maintaining both VL and DL proficiency since DL can be a more appropriate choice for some patients.

Ruthie's Table 4
For more than 30 years The River Cafe in London, has been the home-from-home of artists, architects, designers, actors, collectors, writers, activists, and politicians. Michael Caine, Glenn Close, JJ Abrams, Steve McQueen, Victoria and David Beckham, and Lily Allen, are just some of the people who love to call The River Cafe home. On River Cafe Table 4, Rogers sits down with her customers—who have become friends—to talk about food memories. Table 4 explores how food impacts every aspect of our lives. “Foods is politics, food is cultural, food is how you express love, food is about your heritage, it defines who you and who you want to be,” says Rogers. Each week, Rogers invites her guest to reminisce about family suppers and first dates, what they cook, how they eat when performing, the restaurants they choose, and what food they seek when they need comfort. And to punctuate each episode of Table 4, guests such as Ralph Fiennes, Emily Blunt, and Alfonso Cuarón, read their favourite recipe from one of the best-selling River Cafe cookbooks. Table 4 itself, is situated near The River Cafe’s open kitchen, close to the bright pink wood-fired oven and next to the glossy yellow pass, where Ruthie oversees the restaurant. You are invited to take a seat at this intimate table and join the conversation.
