Study Notes
Analgesia, Sedation, and Local Anaesthetics: A Comprehensive Overview by Dr. Jim Cooper
- Pain is defined as an unpleasant sensory and emotional experience associated with actual or potential tissue damage.
- The Gate Theory of pain explains how pain signals are transmitted through C fibers and inhibited by A delta fibers and descending pathways in the central nervous system.
- Pain can be modified through various methods, including the use of analgesics and anesthetics.
- The pain ladder is a classification system for pain management, ranging from mild to severe, and includes the use of NSAIDs, weak opiates, and strong opiates.
- Opioids act on opioid receptors, with different types of opioids including naturally occurring (e.g., morphine), semi-synthetic (e.g., diamorphine), and synthetic (e.g., fentanyl).
- Opioid receptors are found in various locations, including the pons and midbrain, periaqueductal grey matter, spinal cord, and peripheral tissues.
- Opioids can have side effects such as respiratory depression, nausea and vomiting, constipation, and miosis.
- Naloxone is an important antidote for opioid overdose and should be used with caution.
- Ketamine acts on NMDA receptors and kappa and delta receptors, and it can be used as an analgesic, local/general anesthetic, and sedative.
- NSAIDs work by inhibiting cyclooxygenase 1 and 2 and have analgesic, antipyretic, and anti-inflammatory effects, but they can also cause gastric irritation, bronchospasm, renal impairment, and platelet function.
- Local anesthetics, such as lignocaine and bupivacaine, work by blocking sodium channels and can be administered in various locations, including the skin, subcutaneous tissue, brachial plexus, epidural space, and caudal space.
- Local anesthetics can have side effects such as vascular and nerve toxicity, leading to dysrhythmias, cardiac depression, fitting/anxiety/loss of consciousness, and circumoral numbness. Treatment for toxicity includes ABC (airway, breathing, circulation), oxygen, and lipid 20%.
