Study Notes

Maintenance of Surgical Anesthesia

Involves management of physiological functions and maintenance of anesthesia from induction to emergence.
Goals include maintaining physiologic homeostasis and ensuring unconsciousness, amnesia, analgesia, immobility, muscle relaxation, and control of sympathetic nervous system.
Combination of inhaled and IV drugs is utilized depending on the procedure.

Fluid Management

Maintain euvolemia for normotensive patients.
Traditional approach vs. goal-directed fluid replacement strategy.
Monitor urine output and replace fluids as needed during NPO or bowel prep.

Maintenance Monitoring

Continuous vigilance is required to monitor:
- Oxygenation and vital signs
- Anesthetic depth and muscle relaxation
- Patient positioning to prevent nerve injury

Stages of General Anesthesia

Stage I (Analgesia): Starts with induction agents, ends with loss of consciousness.
Stage II (Delirium): Characterized by excitation, involuntary movements, and unstable vital signs.
Stage III (Surgical Anesthesia): Deep sleep with four distinct planes; most surgeries occur here.
Stage IV (Overdose): Total respiratory paralysis; must be reversed to prevent circulatory collapse.

Emergence from Anesthesia

Transition from anesthesia to consciousness involves recovery of airway reflexes.
Tailor emergence plans based on patient's comorbidities and surgical needs.
Administer reversal agents and assess level of paralysis, ensuring adequate recovery before extubation.

Awake vs. Deep Extubation

Awake extubation occurs when the patient responds to commands and breathes spontaneously.
Deep extubation is used to prevent 'bucking' during emergence in suitable candidates.

Monitored Anesthesia Care (MAC)

A service facilitating varied levels of sedation and maintaining patient comfort during procedures.
The anesthesia provider must be ready to transition to general anesthesia if needed.
Key for ensuring vital functions are supported throughout the procedure.

Sedation Levels and Characteristics

Minimal Sedation (Anxiolysis): Patients respond to verbal commands; airway reflexes intact.
Moderate Sedation/Analgesia (Conscious Sedation): Patients can respond to commands; maintain a patent airway.
Deep Sedation/Analgesia: Patients not easily aroused; may require airway assistance; maintains cardiovascular stability.

Risks and Considerations

Oversedation and respiratory collapse are frequent issues leading to claims in MAC.
Certain patients (children, confused, uncooperative) may not be good candidates for MAC.
Continuous monitoring and accessible airway equipment are crucial.
