Anesthesia bridges physiology, pharmacology, and procedural skill to provide safe perioperative care and pain management. Volume 1 introduces anesthetic pharmacology, airway management, monitoring technologies, and the physiologic basis of anesthesia care. It describes preoperative assessment, perioperative risk stratification, and basic regional and general anesthesia techniques with practical checklists. Emphasis on safety, simulation-based training tips, and crisis algorithms prepares learners for common intraoperative challenges. Clear illustrations and stepwise procedures make it suitable for trainees and allied health professionals.
