Study Notes
Anesthesiology Study Notes
General Anesthesia
- Induces unconsciousness and lack of sensation.
- Administered via inhalation or intravenous (IV) routes.
- Stages:
- Induction: Onset of anesthesia.
- Maintenance: Sustain anesthesia during procedures.
- Emergence: Transition to consciousness.
- Common agents: Propofol, Sevoflurane, Isoflurane.
Pain Management
- Focus on alleviating pain during and post-surgery.
- Techniques include:
- Opioids: Morphine, Fentanyl, Hydromorphone.
- Non-opioids: NSAIDs, Acetaminophen.
- Adjuncts: Antidepressants, anticonvulsants.
- Multimodal approach: Combination of medications to enhance efficacy and reduce side effects.
Anesthesia Monitoring
- Continuous assessment of patient’s vital signs.
- Key parameters:
- Heart rate and rhythm.
- Blood pressure.
- Oxygen saturation (SpO2).
- End-tidal carbon dioxide (ETCO2).
- Use of monitors: ECG, pulse oximeter, capnometer.
Sedation Techniques
- Used for procedures requiring reduced consciousness.
- Levels of sedation:
- Minimal: Patient responds to verbal commands.
- Moderate: Patient may not respond to verbal commands.
- Deep: Patient cannot be easily aroused.
- Agents: Midazolam, Propofol, Dexmedetomidine.
Regional Anesthesia
- Blocks sensation in specific body areas.
- Types:
- Nerve blocks: Targeting specific nerves (e.g., femoral nerve block).
- Spinal anesthesia: Injection into the subarachnoid space.
- Epidural anesthesia: Injection into the epidural space.
- Advantages: Reduced systemic effects and quicker recovery.
Anesthetic Pharmacology
- Study of drug mechanisms and effects on the body.
- Key concepts:
- Pharmacokinetics: Absorption, distribution, metabolism, excretion.
- Pharmacodynamics: Drug action and effect.
- Drug classes:
- Inhalational agents: Volatile anesthetics, nitrous oxide.
- IV agents: Barbiturates, benzos, opioids.
- Considerations: Dosing variations based on age, weight, and comorbidities.
General Anesthesia
- Induces unconsciousness and lack of sensation during surgical procedures.
- Administered through inhalation or intravenous (IV) methods.
- Consists of three stages:
- Induction: Rapid onset of anesthesia.
- Maintenance: Sustains anesthesia throughout the procedure.
- Emergence: Patient transitions back to consciousness.
- Commonly used agents include Propofol, Sevoflurane, and Isoflurane.
Pain Management
- Aims to alleviate pain before, during, and after surgery.
- Utilizes various techniques, including:
- Opioids like Morphine, Fentanyl, and Hydromorphone for severe pain.
- Non-opioids such as NSAIDs and Acetaminophen for mild to moderate pain.
- Adjunct medications like antidepressants and anticonvulsants for enhanced effectiveness.
- Employs a multimodal approach to combine medications, maximizing pain relief while minimizing side effects.
Anesthesia Monitoring
- Continuous monitoring of vital signs is critical for patient safety.
- Key parameters include:
- Heart rate and rhythm for cardiac assessment.
- Blood pressure to ensure stable hemodynamics.
- Oxygen saturation (SpO2) for respiratory monitoring.
- End-tidal carbon dioxide (ETCO2) levels.
- Utilizes various monitoring devices, including ECG, pulse oximeters, and capnometers.
Sedation Techniques
- Implemented for procedures that require reduced consciousness but not full anesthesia.
- Levels of sedation are categorized as:
- Minimal: Patient responds to verbal stimuli.
- Moderate: Patient may not respond to commands but can be aroused.
- Deep: Patient is difficult to arouse and may not respond to verbal commands.
- Common agents for sedation include Midazolam, Propofol, and Dexmedetomidine.
Regional Anesthesia
- Targets specific areas of the body to block sensation.
- Includes methods such as:
- Nerve blocks that focus on particular nerves (e.g., femoral nerve block).
- Spinal anesthesia involving injection into the subarachnoid space.
- Epidural anesthesia, which is administered into the epidural space.
- Advantages of regional anesthesia include fewer systemic side effects and faster recovery times.
Anesthetic Pharmacology
- Involves the study of how anesthetic drugs affect the body.
- Key concepts include:
- Pharmacokinetics: Examines drug absorption, distribution, metabolism, and excretion.
- Pharmacodynamics: Describes the drug's action and effects on the body.
- Drug classes are categorized as:
- Inhalational agents, including volatile anesthetics and nitrous oxide.
- IV agents such as barbiturates, benzodiazepines, and opioids.
- Dosing considerations vary depending on patient factors like age, weight, and pre-existing conditions.
