Robot-assisted thoracoscopic thymectomy: perianaesthetic concerns

Area of Science:

• Anesthesiology
• Thoracic Surgery
• Robotic Surgery

Background:

• Robot-assisted thoracoscopic thymectomy introduces novel challenges for anesthesiologists.
• This study examines anesthetic management in 17 patients undergoing robotic thymectomy.

Purpose of the Study:

• To evaluate the anesthetic management and potential complications of robot-assisted thoracoscopic thymectomy.
• To identify areas for technique refinement in robotic thymectomy anesthesia.

Main Methods:

• Prospective study of 17 myasthenia gravis patients undergoing robotic thymectomy.
• Anesthesia induced with fentanyl, propofol, sevoflurane; neuromuscular blockade with atracurium.
• Utilized double lumen tube, capnography, entropy, and neuromuscular monitoring; initiated one-lung ventilation and capnomediastinum.

Main Results:

• All patients experienced transient arrhythmias and hypotension.
• Capnomediastinum creation increased airway pressure and central venous pressure.
• Complications included pleural rent (2), ventilatory difficulty (2), brachial plexus injury (1), and hoarseness (2).

Conclusions:

• Surgical technique refinement is needed to prevent robotic arm compression, especially on upper extremities.
• Optimize double lumen tube placement to avoid robotic arm interference.
• Continuous monitoring of airway pressure and capnography is essential for detecting capnothorax; vigilance for nerve injury is recommended.
