EDAIC - European Diploma in Anesthesiology and Intensive Care Respiratory and Thoracic Anesthesia Questions and Answers

Question 1

Which of the following anesthetic agents is known to most significantly inhibit hypoxic pulmonary vasoconstriction (HPV), potentially worsening oxygenation during one-lung ventilation?

Accepted Answer

Nitroglycerin

Answer

Desflurane

Answer

Propofol

Answer

Fentanyl

Question 2

A 68-year-old male with a history of COPD is scheduled for a right upper lobectomy for a lung mass. His preoperative FEV1 is 1.6 L (55% predicted). A quantitative V/Q scan shows the right upper lobe contributes 20% to total lung function. What is the best estimate of his predicted postoperative FEV1 (ppoFEV1)?

Accepted Answer

1.28 L

Answer

1.44 L

Answer

0.88 L

Answer

1.06 L

Question 3

Which of the following is considered the most serious, albeit infrequent, major complication associated with mediastinoscopy?

Accepted Answer

Major hemorrhage

Answer

Pneumothorax

Answer

Recurrent laryngeal nerve injury

Answer

Tracheal compression

Question 4

During a left thoracotomy with one-lung ventilation (OLV), a patient's SpO2 drops to 85% despite an FiO2 of 1.0. The double-lumen tube's position has just been confirmed as correct with a fiberoptic bronchoscope. According to standard management algorithms, what is the most appropriate next step?

Accepted Answer

Apply Positive End-Expiratory Pressure (PEEP) to the dependent (ventilated) lung.

Answer

Apply Continuous Positive Airway Pressure (CPAP) to the non-dependent lung.

Answer

Briefly re-inflate the non-dependent lung.

Answer

Increase the tidal volume to the dependent lung.

Question 5

For postoperative pain management following a posterolateral thoracotomy, which regional anesthesia technique is considered to provide analgesia of similar efficacy to a thoracic epidural but with a more favorable side-effect profile?

Accepted Answer

Paravertebral block

Answer

Intercostal nerve block

Answer

Serratus anterior plane block

Answer

Erector spinae plane block

Question 6

Which of the following is a primary anesthetic goal during induction for a patient with a large, high-flow bronchopleural fistula (BPF) requiring surgical repair?

Accepted Answer

Maintain spontaneous ventilation until the affected lung is isolated.

Answer

Administer a high-dose opioid bolus to blunt the stress response.

Answer

Maximize positive pressure ventilation to ensure oxygenation.

Answer

Place the patient in the Trendelenburg position to improve pre-oxygenation.
