NEUROSCIENCE OF PAIN AND ANESTHESIA: Molecular Mechanisms, Clinical Pharmacology, Perioperative Analgesia, and Translational Therapies

A comprehensive clinical and scientific guide to pain neuroscience, anesthesia, analgesic pharmacology, and emerging therapies

Neuroscience of Pain and Anesthesia connects the molecular biology of nociception with the practical management of acute, chronic, perioperative, neuropathic, cancer-related, and complex pain conditions. Written for clinicians, trainees, researchers, and healthcare professionals, this first edition explains how pain signals are generated, transmitted, modified, perceived, and treated.

The book begins with the neural anatomy of pain, including peripheral nociceptors, spinal processing, ascending pathways, cortical networks, and descending inhibitory systems. It then examines ion channels, neurotransmitters, inflammatory mediators, neuroimmune interactions, peripheral sensitization, central sensitization, glial activation, and the neuroplastic mechanisms that contribute to persistent pain.

Clinical chapters provide detailed coverage of pain classification, bedside assessment, quantitative sensory testing, opioid and non-opioid analgesics, general anesthesia, regional anesthesia, local anesthetics, neuromuscular blockade, postoperative pain management, and enhanced recovery protocols.

Major topics include:

Molecular and cellular mechanisms of nociception Peripheral and central pain sensitization Acute, chronic, neuropathic, inflammatory, and nociplastic pain Opioid pharmacology, tolerance, dependence, and hyperalgesia NSAIDs, acetaminophen, antidepressants, anticonvulsants, and topical therapies General anesthetics and mechanisms of unconsciousness Spinal, epidural, and ultrasound-guided regional anesthesia Local anesthetic systemic toxicity and emergency management Neuromuscular blocking drugs and reversal agents Multimodal perioperative analgesia and patient-controlled analgesia Neuropathic pain, cancer pain, and palliative analgesia Pediatric, obstetric, geriatric, and cognitively impaired patients Visceral pain, musculoskeletal pain, low back pain, and fibromyalgia Spinal cord stimulation, radiofrequency ablation, and intrathecal therapy Psychological approaches to chronic pain Opioid addiction, harm reduction, and responsible prescribing Gene therapy, monoclonal antibodies, artificial intelligence, and precision medicine Ethical, legal, regulatory, and global perspectives on pain treatment The text integrates basic neuroscience, clinical pharmacology, anesthetic practice, interventional pain medicine, psychology, ethics, and translational research. It is suitable for anesthesiologists, pain physicians, neurologists, surgeons, pharmacists, nurses, residents, fellows, medical students, and researchers seeking a structured reference on modern pain and anesthesia science.

A practical resource for understanding pain mechanisms, selecting appropriate therapies, improving perioperative analgesia, and evaluating the future of pain medicine.
