Study Notes
Anesthesia Overview
- Types of anesthesia include obstetric, pediatric, cardiothoracic, neuro, outpatient surgery, and pain management.
- Ketamine clinics offer specialized anesthetic care.
- Alice Magaw is recognized as the first nurse anesthetist.
Historical Milestones
- 1864 marks the delivery of the first ether anesthetic by Morton.
- WWII saw the establishment of modern anesthetic practices.
Considerations for Anesthetic Technique
- Factors influencing anesthetic choices: patient safety, comfort, provider preference, coexisting diseases, surgical site, positioning, airway management, surgery duration, age, and recovery time.
- Facilities have specific PACU discharge criteria.
Ideal Anesthetic Technique Goals
- Ensure optimal patient safety, satisfaction, and excellent surgeon operating conditions.
- Aim for rapid recovery and minimize postoperative side effects while reducing costs.
Types of Anesthesia
- General Anesthesia: Drug-induced CNS depression resulting in unresponsiveness to external stimuli.
- ASA continuum of sedation ranges from minimal to deep sedation levels.
General Anesthetic Methods
- Methods include inhalation only (often for pediatric cases), intravenous (TIVA used in neuro-monitored scenarios), and a combination of inhalation and IV, which is the most common.
Inhalation Induction
- Most common method for pediatric patients in elective cases, resulting in less trauma (known as mask induction).
- Process includes administering oxygen and volatile agents to achieve loss of consciousness.
Monitoring During Anesthesia
- Monitors such as pulse oximetry are critical throughout the induction and maintenance phases.
- Post-induction assessment includes loss of lid reflex and ease of ventilation.
Maintenance of Anesthesia
- Involves managing physiological functions until emergence from anesthesia.
- Goals include maintaining unconsciousness, amnesia, analgesia, and muscle relaxation.
- Vigilance is essential to respond to any physiological changes.
Neuroaxial Anesthesia
- Local anesthetic placement near the spinal cord, blocking nerve signals to and from the brain.
- Can be administered as a single injection (spinal) or via a catheter for continuous infusion (epidural).
Advantages of Regional Anesthesia
- Compared to general anesthesia, regional methods can reduce blood loss, venous thromboembolism, cardiac complications, and postoperative ileus.
- Regional anesthesia is often preferred for procedures below the umbilicus.
Anatomy of the Vertebral Column
- Comprised of 33 vertebral bones and 24 intervertebral disks, providing structural support and protection for the spinal cord.
- Consists of cervical, thoracic, lumbar, sacral, and coccygeal regions with characteristic curvatures.
Meninges and Spinal Cord Structure
- The spinal cord is encased in three protective membranes: dura mater, arachnoid mater, and pia mater.
- Cerebrospinal fluid (CSF) is located in the subarachnoid space, providing cushioning.
Anesthesia Candidates
- Not ideal for children, uncooperative or confused patients, or those unable to maintain a stable position.
ASA Sedation Levels
- Minimal Sedation: Patients respond to verbal commands; cognitive function may be impaired.
- Moderate Sedation: Purposeful response to verbal commands or light touch; airway and spontaneous ventilation remain sufficient.
- Deep Sedation: Patients are difficult to arouse but respond to pain; airway maintenance may be needed.
Epidural and Subarachnoid Spaces
- Epidural space is outside the dura mater and contains vessels, fat, and nerve roots; it is a potential space subject to variability in size.
- Subarachnoid space contains CSF and connects to the brain's ventricles.
AANA Standards for Nurse Anesthesia Practice
- Thorough preanesthesia assessment and evaluation must be performed and documented.
- Informed consent is required from the patient or legal guardian, or verification of consent obtained by a qualified professional.
- Develop a patient-specific plan for anesthesia care.
- Anesthesia care plan implementation must adapt based on the patient's physiologic status.
- Continuous assessment of the patient's response to anesthetic and surgical interventions is essential, with timely interventions to maintain optimal condition.
Monitoring Standards
- Continuous monitoring of patient's physiologic condition tailored to the anesthesia type and patient needs.
- Oxygenation should be monitored using clinical methods and pulse oximetry; arterial blood gas analysis is used if needed.
- Ventilation monitoring involves auscultation and confirming trachea intubation via expired carbon dioxide levels.
- Cardiovascular status monitored through ECG; blood pressure and heart rate must be documented every five minutes.
- Body temperature is monitored to maintain normothermia when changes are suspected.
- Neuromuscular response should be monitored when neuromuscular blocking agents are used.
- Patient positioning and protective measures must be assessed and monitored, ensuring proper safety.
Documentation and Transfer of Care
- Accurate, complete, legible, and timely documentation of anesthesia-related information in the medical record is crucial.
- Evaluate the patient's status for safe transfer of care, ensuring essential information is reported to the next qualified health care provider.
Safety Precautions
- Adherence to safety protocols to mitigate risks of fire, explosion, or equipment malfunction is vital.
- Automatic mechanical ventilation integrity must be monitored with audible alarms for disconnections.
Anesthesia Techniques
- Anesthesia drugs (inhaled and IV) are administered based on pharmacologic effects and specific goals.
- Vigilance is required to prevent intraoperative awareness, especially during stimulating procedures.
- Homeostasis is maintained through euvolemia and proper fluid management, including blood loss monitoring using the 4-2-1 rule.
Monitored Anesthesia Care (MAC)
- MAC is a specific anesthesia service for diagnostic or therapeutic procedures, requiring preparedness to convert to general anesthesia if needed.
- The aim is to maintain patient comfort, cardiorespiratory stability, and prevent recall of unpleasant events.
- Continuous monitoring is essential during MAC, which includes diagnosis and treatment of clinical issues, vital function support, and administration of necessary medications.
Local Anesthetic Guidelines
- Knowledge of local anesthetic characteristics, recommended doses, and maximum doses is vital.
- Candidates who are confused, uncooperative, or unable to follow commands are generally unsuitable for local anesthesia.
- Oversedation and respiratory collapse are primary concerns in MAC, underscoring the importance of vigilant monitoring and preparedness for airway intervention.
Sedation Levels
- Minimal sedation (anxiolysis) allows normal response to verbal commands while maintaining airway reflexes and cardiovascular function.
- Moderate sedation (conscious sedation) results in purposeful responses to verbal commands, with adequate spontaneous ventilation and maintained cardiovascular stability.
