#319 Four New Studies That Change Daily Anesthesia Safety Decisions

Ketamine for emergency intubation has a reputation for hemodynamic stability, but does the best evidence back that up when your patient is truly sick? Today, we walk through four fresh research summaries that sharpen day-to-day anesthesia patient safety decisions, from airway management in shock and sepsis to the way teams and technology shape outcomes in the OR.First, we break down a large randomized controlled trial comparing ketamine versus etomidate for tracheal intubation in critically ill adults across U.S. emergency departments and ICUs. Mortality is similar, but ketamine shows more peri-intubation cardiovascular collapse, including hypotension and increased vasopressor use, especially in sicker patients. Our practical focus is how to choose an induction agent based on hemodynamic risk and how to prepare for peri-intubation instability.Next, we head into the cardiac OR to explore why surgeon-anesthesiologist dyad familiarity may be a systems-level patient safety strategy. A large retrospective study links more consistent pairings with lower operative mortality and better perioperative outcomes, raising real questions about scheduling, teamwork, and communication under pressure. We also review evidence on BIS-guided closed-loop anesthesia systems that improve anesthetic depth control by reducing excessively deep anesthesia without increasing light anesthesia, and we close with perioperative brain health, highlighting why routine preoperative cognitive screening is still uncommon and what resources could finally make it standard practice.Subscribe to the Anesthesia Patient Safety Podcast, share this with a colleague, and leave a review so more clinicians can find the latest evidence-focused perioperative safety insights.For show notes & transcript, visit our episode page at apsf.org: https://www.apsf.org/podcast/319-four-new-studies-that-change-daily-anesthesia-safety-decisions/© 2026, The Anesthesia Patient Safety Foundation
