Caffeine Accelerates Recovery from General Anesthesia via Multiple Pathways

Currently, there is no method to accelerate emergence from anesthesia. Patients “wake” when they clear the anesthetic from their systems. Previously, we have shown that caffeine can accelerate emergence from anesthesia. In this study, we show that caffeine is effective even at high levels of anesthetic. We also show that caffeine operates by both elevating intracellular cAMP levels and by blocking adenosine receptors. This complicated pharmacology makes caffeine especially effective in accelerating emergence from anesthesia.
