About this listen
- Anesthesia is not static; it is a living discipline that evolves with every patient, study, and clinical encounter.
- The OR tempts anesthesiologists to fall back on routine—repetition feels safe.
- The real risk is not mistakes, but not knowing what you don’t know.
- Maturity in anesthesia lies in recognizing knowledge gaps and addressing them continually.
- Each case is both a challenge and a learning opportunity.
Case 1 — When Familiarity Breeds Blindness: The "Routine" Laparoscopic CholecystectomyThe Scenario
- 54-year-old woman, obese (BMI 34), hypertensive, ASA II.
- Planned laparoscopic cholecystectomy.
- Standard balanced GA with intubation.
The Knowledge Gap
- Sudden hypotension (MAP 45) and tachycardia (HR 125) after insufflation.
- Initial reflex: fluids and phenylephrine bolus → ineffective.
- True mechanism:
- Pneumoperitoneum ↑ intra-abdominal pressure → ↓ venous return → ↓ cardiac output.
- Reverse Trendelenburg further reduces preload.
- Obesity worsens baseline diaphragmatic mechanics and venous return.
The Growth Point
- Release pneumoperitoneum temporarily.
- Flatten table, reassess hemodynamics.
- Corrects issue without unnecessary vasopressors.
Lesson
- Applying pathophysiology transforms crisis management.
- "Routine" cases are not routine when physiology is forgotten.
Case 2 — The Unfamiliar Depths: Desaturation During Prone Spine SurgeryThe Scenario
- 62-year-old male with COPD and mild pulmonary hypertension.
- Lumbar decompression under GA.
- Intubation uneventful, but after prone positioning → SpO₂ drops to 88%.
The Knowledge Gap
- Common reflex: increase FiO₂.
- Missed physiology:
- Prone positioning may reduce FRC if abdomen compressed.
- COPD → low FRC forces tidal volumes into smaller units → increased shunt.
- Pulmonary hypertension limits reserve, risks RV strain during hypoxia.
The Growth Point
- Adjust positioning to free abdomen.
- Moderate PEEP and gentle recruitment.
- Restore oxygenation without excessive pressures.
Lesson
- Troubleshooting requires understanding V/Q mechanics, not just treating numbers.
- Without physiology, responses are blind guesses.
Why Facing Gaps Is Harder Than Following Routine
- Admitting ignorance is uncomfortable. It means:
- Accepting you don’t know something you should.
- Realizing you may have been getting by without knowing.
- Committing time and effort to truly learn.
- In anesthesia, quick fixes work for physiology—not for ignorance.
- Mastery comes only through deliberate, incremental learning.
From Passive to Active Learning in the ORStrategies for Growth
- Micro-reflection: After each case, ask: What did I not fully understand?
- One-concept learning: Learn one new mechanism, drug effect, or disease feature daily.
- Cross-disciplinary study: Physiology, pharmacology, immunology, genetics all enrich practice.
- Scenario rehearsal: Imagine worst-case events and...
