This South Asian Edition is an extension to the long time “go to” book Stoelting's Pharmacology & Physiology in Anesthetic Practice. It strives to be the backbone of modern-day evidence-based anesthesia practice, the “dharma” (principle foundation) of which is to maintain normal patient physiology during the peri-operative period, regardless of numerous drugs (pharmacology) needed to ensure complete and safe anesthesia. The aim of this book is to lay a strong foundation for an anesthetist with regard to basic sciences involved in anesthesia and enable him/her to be an efficient “perioperative physician.
