Many cases have been reported of hemodynamic and airway collapse induced by general anesthesia in patients with an anterior mediastinal mass. We examined the literature for predictors of perioperative risk, guidelines for preoperative investigations, and strategies for management of the patient with a mediastinal mass. ⋯ It appears prudent to avoid general anesthesia when possible for patients at the highest risk. When general anesthesia is required, a comprehensive plan must be formulated preoperatively with the surgical team. Cardiopulmonary bypass requires time for implementation, so it should be considered early and appropriate preparations should be made prior to the initiation of anesthesia.

Randomized Controlled Trial Comparative Study
The McIvor blade improves insertion of the LMA ProSeal™ in children.
The McIvor blade, a tongue retractor with a thin curved blade, is used to improve the operating field during a tonsillectomy. We compared the success rate and incidence of complications between digital insertion and McIvor blade-guided insertion of the laryngeal mask airway (LMA™) ProSeal™ when performed by anesthesia residents in children. ⋯ When inserting the LMA ProSeal in children, anesthesia residents were more successful using the McIvor blade-guided insertion technique than using the digital insertion technique.
