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.
