Emergence From Anesthesia 1 - Tissue Blood Partition Co-Efficients

This tutorial explains why emergence from volatile anesthesia depends on more than simply turning off the vaporizer. It reviews how blood gas partition coefficients influence onset, how oil gas partition coefficients relate to potency and MAC, and then focuses on tissue blood partition coefficients as a key determinant of recovery. The tutorial describes anesthetic uptake into blood, muscle, and fat during short, intermediate, and long cases, showing how tissue storage increases with time and with agent solubility. It also explains tissue back diffusion, where anesthetic stored in tissues continues to return to the blood and brain after the vaporizer is turned off, delaying wake-up. Finally, it compares volatile agents such as nitrous oxide, desflurane, sevoflurane, isoflurane, halothane, and methoxyflurane, emphasizing how lower tissue solubility produces faster, more predictable emergence. ‪@ccmtutorials‬
