Standard Operating Procedure: Anesthesia Administration and Monitoring

This Standard Operating Procedure (SOP) defines the systematic approach to the preparation, administration, and continuous monitoring of anesthesia in a clinical setting. The objective of this document is to ensure the highest standards of patient safety, minimize the risk of adverse physiological events, and provide a standardized workflow for all clinical personnel. Compliance with this SOP is mandatory for all licensed anesthesia providers and support staff to ensure consistency in care and adherence to institutional safety protocols.

Phase 1: Pre-Anesthetic Evaluation and Equipment Setup

• Verify patient identity using two patient identifiers (Name and Date of Birth).
• Review the patient’s medical history, including allergies, current medications, NPO status, and previous anesthetic complications.
• Conduct the "SOAP ME" equipment check:
  • Suction: Ensure the suction device is functional and set to the appropriate pressure.
  • Oxygen: Verify backup oxygen supply and primary pipeline source.
  • Airway: Confirm availability of laryngoscopes (checked for light), endotracheal tubes, and backup airway devices (e.g., LMA, bougie).
  • Pharmaceuticals: Audit all emergency drugs (e.g., epinephrine, succinylcholine, phenylephrine) and induction agents for expiration dates.
  • Monitoring: Confirm functionality of ECG, SpO2, capnography, and non-invasive blood pressure (NIBP).
  • Equipment: Check anesthesia machine circuit integrity and perform a leak test.

Phase 2: Induction and Airway Management

• Position the patient correctly for induction to optimize airway access.
• Apply non-invasive monitoring and establish baseline vitals before the administration of sedative/induction agents.
• Perform a formal pre-oxygenation sequence (denitrogenation) to maximize the patient’s safe apnea window.
• Administer induction agents per the weight-based protocol or physician order.
• Secure the airway, verify placement via capnography (ETCO2), and auscultate bilateral breath sounds.
• Secure the airway device and verify cuff inflation pressure.

Phase 3: Intraoperative Maintenance and Monitoring

• Maintain anesthetic depth using appropriate inhalational agents or TIVA (Total Intravenous Anesthesia) titration.
• Perform continuous monitoring of hemodynamic stability, including heart rate, blood pressure, and rhythm.
• Document vitals at minimum 5-minute intervals in the electronic medical record.
• Manage fluid balance and thermoregulation throughout the procedure.
• Maintain depth of anesthesia to prevent awareness while avoiding excessive hypotension.

Phase 4: Emergence and Transfer of Care

• Taper anesthetic agents as the surgical procedure nears completion.
• Assess patient for readiness to extubate (e.g., spontaneous respiratory effort, hemodynamic stability, protective airway reflexes).
• Perform extubation in a controlled manner, ensuring adequate suctioning of the oropharynx.
• Transition the patient to supplemental oxygen and monitor for respiratory distress.
• Complete a thorough handoff to the Post-Anesthesia Care Unit (PACU) nurse using the SBAR (Situation, Background, Assessment, Recommendation) framework.

Pro Tips & Pitfalls

• Pro Tip: Always have a "Plan B" airway strategy visible and ready. Never wait for an emergency to realize your glidescope or difficult airway cart is missing a component.
• Pro Tip: Use capnography as your primary tool for monitoring respiratory adequacy; it provides earlier warning than pulse oximetry for airway compromise.
• Pitfall: Over-reliance on automation. Technology (monitors/pumps) can fail or provide false readings. Always validate machine data with clinical observation (e.g., palpating a pulse if the blood pressure reading seems anomalous).
• Pitfall: "Distraction creep." Avoid non-clinical conversations during critical stages like induction and emergence, as this is when the majority of patient safety events occur.

Frequently Asked Questions (FAQ)

1. What should be done if the capnography waveform is lost suddenly? Immediately verify the airway. Check for dislodgement, obstruction, or equipment disconnection. Ensure the patient is oxygenating; if the cause is not immediately identifiable, be prepared to mask ventilate and re-intubate if necessary.

2. How often should anesthesia drugs be verified? All medications must be double-checked by the provider before injection. If the medication is a high-alert drug (e.g., concentrated potassium, potent opioids), a second qualified clinician should verify the dosage and identity.

3. What is the most critical step during the handoff process? The most critical step is the communication of the "active issues." This includes recent hemodynamic instability, the status of the airway, recent drug administration, and any specific concerns regarding the surgical site or potential postoperative pain management.
