Neuropharmacology of Anesthesia and Analgesia

This topic provides a comprehensive overview of drugs used in anesthesia and pain management, including inhalational agents (e.g., halothane, nitrous oxide), intravenous anesthetics (e.g., propofol, ketamine), and opioids (e.g., morphine). For Zambian diploma and degree students in medicine, anesthesia, and pharmacy, understanding the pharmacokinetics, mechanisms of action, and adverse effect profiles of these agents is essential for safe perioperative care. The material addresses specific considerations for the Zambian context, such as the phase-out of halothane due to hepatotoxicity and the selection of safer alternatives. It covers crucial concepts like balanced anesthesia, dissociative anesthesia, and the management of pain in conditions like myocardial infarction or pancreatitis. Mastery of this topic is vital for passing pharmacology exams, succeeding in clinical rotations in surgery and ICU, and ensuring patient safety in operating theatres across Zambian hospitals.
