Study Notes

Historical Context of Anesthesia

  • Lack of effective pain control hindered surgical treatment for years.
  • Early surgical success relied on quick operations and patient tolerance to pain.
  • Initial pain relief attempts with opium and alcohol were ineffective and unsafe.
  • The discovery of ether and nitrous oxide during the Renaissance went unrecognized until October 16, 1846.

Advancement in Anesthesia

  • William Morton conducted the first clinical demonstration of anesthesia at Massachusetts General Hospital.
  • Modern anesthetic agents and techniques have transformed surgical practice.
  • Anesthetics enhance surgical efficiency and enable previously unfeasible procedures.

Components of Modern Anesthesia

  • Involves pain relief, physical comfort, mental health, and physiological support.
  • Anesthesia staff includes anesthesiologists and certified registered nurse anesthetists (CRNAs), supported by surgical technicians and nurses.
  • All surgical nursing personnel should understand modern anesthesia related to perioperative care.

Types of Anesthesia

  • General Anesthesia: Characterized by amnesia, analgesia, hypnosis, and muscle relaxation; induces a state referred to as “going to sleep.”
  • Conduction/Regional Anesthesia: Involves injecting a local anesthetic near nerves for pain relief in specific body areas while maintaining consciousness.
  • Monitored Anesthesia Care (MAC): Combines sedation with local or regional anesthesia for minor procedures.

Factors Influencing Anesthetic Choice

  • Age, physical condition, uncommon medical conditions, drug allergies, personal preference, previous experiences, medical contraindications, and lab test results.
  • Anesthetists tailor the anesthetic approach to individual patient needs.

Patient Specific Considerations

  • Age: Younger and older patients may require different anesthetic techniques.
  • Physical Condition: Existing diseases (e.g., diabetes, hypertension) can influence agent selection.
  • Allergies: History of drug sensitivities affects anesthetic choices.
  • Previous Experience: Past reactions to anesthetics guide future selections.

American Society of Anesthesiologists Physical Status Classification

  • A system to classify patients:
    • ASA Class 1: Healthy
    • ASA Class 2: Mild to moderate systemic disease
    • ASA Class 3: Severe systemic disease
    • ASA Class 4: Life-threatening disease
    • ASA Class 5: Critical patients not expected to survive
    • Emergency cases add “E” to the classification.

Preoperative Medication

  • Administered for psychological (anxiety reduction) and physiological (medical stability) needs.
  • Common premedication includes sedatives, antacids, and anticholinergics.

Common Preoperative Medications

  • Sedatives/Tranquilizers: Barbiturates (e.g., secobarbital), nonbarbiturate options (e.g., lorazepam).
  • Narcotics: Used for pain relief (e.g., morphine) but require close monitoring for respiratory depression.
  • Anticholinergic Agents: Reduce secretions (e.g., atropine) and manage dry field conditions during surgery.

Additional Considerations for Premedication

  • Timing is crucial; medications are administered 45-60 minutes before surgery.
  • Exceptions for premedication occur for elderly or critically ill patients, who may receive sedatives in the surgical suite.

Conclusion

  • Comprehensive understanding of anesthesia selection and preoperative medication is essential for perioperative nursing staff.
  • Emphasis on patient safety, comfort, and effective surgical outcomes is paramount in anesthesia management.
