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.
