    Study Notes

    Types of Anesthesia

    • Anesthesia provides loss of consciousness, analgesia (insensibility to pain), hypnosis (artificial sleep), and relaxation (reduced tension in targeted areas).
    • Pain control during surgery is achieved using anesthetic medications, allowing for better control of respiration and cardiovascular functions.

    General Anesthesia

    • Induces unconsciousness and is primarily administered through intravenous drugs and inhaled gases.
    • Common methods include inhalation of gaseous agents like nitrous oxide, halothane, enflurane, sevoflurane, and isoflurane combined with oxygen as a carrier.
    • Gaseous agents are colorless and odorless, commonly used for analgesia in surgeries.

    Intravenous Anesthesia

    • Deliver anesthetics directly into the bloodstream via a peripheral vein.
    • Common drugs include Pentothal sodium (a barbiturate), Fentanyl (opioid), Demerol (opioid), and Propofol (sedative and hypnotic).
    • These agents alter brain activities to provide sedation and pain relief.

    Techniques of Anesthesia

    • Topical Anesthesia: Applied directly to skin or mucous membranes. Common examples include Lidocaine and Benzocaine.
    • Local Anesthesia: Injected into specific tissues to block pain at nerve endings. Lidocaine is a prominent example.
    • Regional Anesthesia: Achieves loss of sensation in a specific body region, including techniques like nerve blocks and spinal anesthesia.

    Spinal Anesthesia

    • Involves injection into the subarachnoid space, providing loss of sensation below the diaphragm without loss of consciousness. Commonly done via lumbar puncture.
    • Types include:
      • Low Spinal Anesthesia: Targets the saddle region.
      • Mid Spinal Anesthesia: Below the umbilicus.
      • High Spinal Anesthesia: Reaches the nipple line, often used in cesarean sections.

    Epidural Anesthesia

    • Injection into the space surrounding the dura mater of the spinal cord.
    • Used commonly for pain control during labor and delivery, as well as anorectoral and perineal procedures.

    Stages of General Anesthesia

    • Stage 1: Induction: Begins at inhalation, characterized by loss of verbal response, drowsiness, and visual/auditory sensations.
    • Stage 2: Excitement: Marked by loss of eyelid reflexes and irregular respiration; patient may exhibit increased heart rate and dilated pupils.
    • Stage 3: Surgical Anesthesia: Optimal for surgery; patient is motionless with shallow respiration and diminished reflexes.
    • Stage 4: Medullary Depression: Considered dangerous; needs careful monitoring due to severe suppression of respiratory and cardiovascular functions.

    Categories of Anesthesia

    • General Anesthetic Agents: Chemicals like nitrous oxide or volatile liquids that induce general insensibility.
    • Local Anesthetic Agents: Block sensory nervous transmission without inducing loss of consciousness, such as lidocaine and bupivacaine.
