Summary
High spinal anesthesia can reveal undiagnosed obstructive sleep apnea by reducing arousal. This case highlights the importance of monitoring airway obstruction during neuraxial anesthesia.
Area of Science:
- Anesthesiology
- Sleep Medicine
- Neurology
Background:
- Spinal anesthesia with high sensory blockade can affect arousal levels.
- Undiagnosed obstructive sleep apnea (OSA) poses risks during anesthesia.
Observation:
- A patient undergoing femur surgery experienced apneic events during spinal anesthesia.
- These events ceased when the patient was easily aroused.
Findings:
- Postoperative sleep study diagnosed severe obstructive sleep apnea.
- High spinal blockade likely reduced sensory input, decreasing consciousness and unmasking OSA.
Implications:
- Consider OSA in patients with unexplained apneic events under neuraxial anesthesia.
- Continuous monitoring, including capnography, is crucial for patients receiving neuraxial techniques.
- Early diagnosis and treatment of OSA can improve patient outcomes.
