Under pressure: Keep MAP > 65 mm Hg or within 20% of baseline?-Under pressure: Keep MAP

Video Summary

In a recent lecture titled "Under Pressure, Keeping Your MAP Greater Than 65," Dr. Amy Yernden and Dr. Desiree Chappell explored intraoperative hypotension (IOH) and its effects on patient outcomes. Both experts emphasized the significance of keeping the mean arterial pressure (MAP) above 65 mmHg to prevent negative outcomes, such as acute kidney injury (AKI), myocardial injury, and mortality. They discussed the variability in defining hypotension across studies, often focusing on thresholds of MAP less than 65 for varying durations.<br /><br />Yernden and Chappell highlighted the importance of understanding the underlying causes of hypotension and differentiating between absolute and relative thresholds. They presented recent studies indicating that continuous blood pressure monitoring can effectively reduce hypotension's occurrence and severity, arguing for a shift from intermittent cuff measurements. The speakers also discussed advanced hemodynamic monitoring that offers predictive analytics, identifying impending hypotension and offering a guide to treatment.<br /><br />They concluded by stressing the need for education on IOH, advocating for continuous monitoring technologies, and following recommendations set forth by organizations like APSF and POQI for better management of intraoperative blood pressure. They urged for increased awareness and understanding among anesthesia professionals to enhance patient safety and outcomes.
