This course gives anesthesia providers a clear, clinically focused framework for recognizing and treating perioperative acid–base disturbances. You’ll learn when (and when not) to use sodium bicarbonate, how and where alternative buffers like THAM fit in, and how to integrate H₂-receptor antagonists into the management of alkalosis from gastric losses—so you can stabilize vulnerable patients, avoid iatrogenic harm, and confidently navigate complex metabolic derangements in the OR and ICU.
