Summary
Apneic oxygenation is a safe and simple method to maintain oxygenation during thoracic surgery when ventilation is challenging. This technique enhances anesthesiologist flexibility and patient safety in emergencies.
Area of Science:
- Anesthesiology
- Thoracic Surgery
- Respiratory Physiology
Background:
- Boerhaave's syndrome, a spontaneous esophageal rupture, presents a life-threatening condition.
- Anesthesiological management during thoracic surgery for esophageal rupture remains underexplored.
- Standard ventilation techniques can impede surgical access and create adverse situations during thoracic procedures.
Observation:
- A case report details managing a patient with a belatedly diagnosed esophageal rupture requiring surgery.
- During surgery, artificial ventilation obstructed surgeons, necessitating its cessation.
- Apneic oxygenation was employed for 20 minutes to maintain oxygen supply, preventing significant hemodynamic compromise.
Findings:
- Apneic oxygenation, using a reservoir bag with CPAP, successfully maintained oxygenation (paO2 decline from 400 to 100 mmHg) for 20 minutes.
- While oxygen levels decreased, significant changes in heart rate, blood pressure, and oxygen saturation were avoided.
- Arterial carbon dioxide levels increased (pCO2 to 90 mmHg) during the apneic period.
Implications:
- Apneic oxygenation is a viable, simple, and safe alternative respiratory technique during thoracic surgery.
- This method increases anesthesiologist flexibility and patient safety, particularly in emergency situations.
- Knowledge of apneic oxygenation should be integrated into anesthesiology education and clinical practice for thoracic procedures.
