Anesthesia for children with anterior mediastinal masses

Children with an anterior mediastinal mass may have cardiopulmonary compromise that can be exacerbated under general anesthesia. Signs and symptoms such as cough, shortness of breath, stridor, orthopnea, accessory muscle use, a history of respiratory arrest, and the presence of a pleural effusion and upper body edema are predictive of perioperative complications. A larger mediastinal mass on imaging is predictive of perioperative complications. Risk stratification of patients, together with an individualized plan, will best guide operative management for patients with an anterior mediastinal mass. General anesthesia (GA) should be avoided if possible, but a spontaneous breathing technique is recommended if GA is required.
